Complete Guide to the Combined Federal State Filing Program for 1099s in 2026

Introduction: Understanding the Combined Federal State 1099 Filing Program

If you file 1099 information returns with the IRS, you've probably wondered: What is the Combined Federal State Filing Program for 1099s? This program, officially known as the Combined Federal/State Filing Program (CF/SF), is one of the most valuable tools available to businesses, accountants, and payroll providers who need to comply with both federal and state tax reporting requirements. Understanding how the combined federal state 1099 program works can save you significant time, reduce compliance complexity, and help you avoid costly penalties.

Every year, businesses across the United States must report payments made to contractors, vendors, and other payees using various 1099 forms. While the IRS requires these filings at the federal level, most states also want copies of 1099 information to verify that residents and businesses operating within their borders are properly reporting income. Without the CF/SF program, this would mean filing the same information twice for every state that has income tax requirements, a nightmare for businesses with payees spread across multiple jurisdictions.

The Combined Federal State Filing Program eliminates this duplication by allowing the IRS to share your 1099 filing data directly with participating states. When you e-file your 1099s with the IRS and participate in the CF/SF program, you're essentially completing your state filing requirements at the same time, with no additional paperwork, separate submissions, or extra fees. It's a win-win for compliance efficiency.

This comprehensive guide will explain everything you need to know about the Combined Federal State Filing Program, including:

  • How the CF/SF program works and the mechanics of data sharing between federal and state agencies
  • Which states participate in the program and which require separate filings
  • Which 1099 form types are covered by the CF/SF program
  • Requirements for participation and how to ensure your filings qualify
  • Step-by-step instructions for using the CF/SF program effectively
  • Common mistakes that prevent successful CF/SF participation
  • Best practices for maximizing the program's benefits
  • How corrections and amendments work within the CF/SF framework

By the end of this guide, you'll have a complete understanding of how to leverage the Combined Federal State Filing Program to simplify your 1099 compliance obligations and reduce your administrative burden.

What is the Combined Federal State Filing Program?

The Purpose and History of the CF/SF Program

The Combined Federal State Filing Program is an IRS initiative designed to simplify information return compliance by eliminating the need for separate federal and state filings. Under this program, when you electronically file certain information returns with the IRS, the agency automatically forwards the relevant data to participating state tax agencies. This means that one electronic submission satisfies both your federal reporting obligation and your state reporting requirements for participating states.

The CF/SF program was created in recognition of the significant compliance burden that dual federal-state filing imposes on businesses. Before the program existed, a company paying contractors in multiple states would need to file with the IRS and then separately file with each state tax agency, often using different formats, filing methods, and submission portals. For a business with payees in 15 or 20 states, this could mean managing dozens of separate filing processes, each with its own deadlines and requirements.

The IRS established the CF/SF program to reduce this burden while still ensuring that states receive the tax information they need. The program operates on a voluntary basis for states, meaning each state must agree to participate and accept data from the IRS rather than requiring direct submission from filers. Over time, the vast majority of states with income taxes have joined the program, making it an invaluable resource for multi-state filers.

How the CF/SF Program Works: The Data Flow

Understanding how the combined federal state 1099 program works requires following the flow of data from your business to both federal and state agencies. Here's how the process unfolds:

Step 1: You Prepare Your 1099 Forms

You gather all the necessary information for your 1099 filings, including payee names, addresses, TINs (Social Security Numbers or EINs), and payment amounts. Critically, you must include state-level information on each form, specifically the state code (the two-letter abbreviation for the payee's state) and any state tax that was withheld from payments.

Step 2: You E-File with the IRS

You submit your 1099 filings electronically through an authorized method. This could be through a third-party e-file provider like BoomTax, the IRS IRIS system (Information Returns Intake System), or the legacy FIRE system (Filing Information Returns Electronically). When you e-file, the state information you included on each form is captured as part of the submission.

Step 3: The IRS Processes Your Filing

Once the IRS receives your electronic filing, their systems process the data and validate it against their records. After acceptance, the IRS extracts the state-specific information from your filing. Each 1099 form is matched to the appropriate state based on the state code you provided.

Step 4: The IRS Forwards Data to Participating States

For any forms where the payee is located in a state that participates in the CF/SF program, the IRS automatically transmits that data to the state's tax agency. The state receives the same information you filed federally, including payee details, payment amounts, and any withholding information. This transmission happens automatically without any additional action required from you.

Step 5: States Accept the Filing

Participating states accept the data forwarded by the IRS as fulfilling your state filing requirement. You don't need to file separately with these states, register with their systems, or submit anything additional. The state has what it needs to match income reported on individual tax returns.

Key Benefits of the Combined Federal State Filing Program

The CF/SF program offers substantial benefits for businesses and tax professionals:

Simplified Compliance: Instead of managing separate filings for federal and each state, you complete one electronic filing that satisfies multiple obligations. This is especially valuable for businesses with payees in many states.

Time Savings: Preparing and submitting separate state filings takes significant time. The CF/SF program eliminates this work entirely for participating states, freeing up resources for other business activities.

Cost Reduction: Many states charge fees for electronic filing or require registration that involves costs. By satisfying state requirements through the CF/SF program, you avoid these additional expenses.

Reduced Error Risk: Every time you prepare and submit a filing, there's potential for errors. With CF/SF, you only need to get the filing right once for the federal submission, and that correct data flows to all participating states.

No State Registration Required: For CF/SF states, you don't need to register with the state tax agency, obtain filing credentials, or learn each state's specific filing format. The IRS handles the data translation and transmission.

Automatic Deadline Compliance: When you meet the federal e-filing deadline, you automatically meet the state deadlines for CF/SF participating states. There's no risk of missing a state deadline because you forgot about a particular state.

States Participating in the Combined Federal State 1099 Program

Complete List of CF/SF Participating States

The vast majority of states with income taxes participate in the Combined Federal State Filing Program. When you e-file 1099s with the IRS and include the appropriate state information, the following states will automatically receive your filing data:

Region Participating States
Northeast Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, Pennsylvania, Rhode Island, Vermont
Southeast Alabama, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Virginia, West Virginia
Midwest Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, Wisconsin
Mountain/Southwest Arizona, Colorado, Idaho, Montana, New Mexico, Oklahoma, Utah
West Coast & Pacific California, Hawaii, Oregon
Other Arkansas, District of Columbia

This list includes over 40 states and jurisdictions, covering the vast majority of the U.S. population. If your payees are located in these states, participating in the CF/SF program through your federal e-filing satisfies your state filing requirements without additional work.

States NOT Participating in the CF/SF Program

While most states participate in the CF/SF program, there are important exceptions that require separate attention:

New York: The most significant non-participating state is New York. If you have payees located in New York, you must file directly with the New York State Department of Taxation and Finance in addition to your federal filing. This requires a separate electronic submission using New York's specific format and filing requirements. For detailed guidance on filing 1099s with multiple states including New York, see our comprehensive guide.

States Without Income Tax: Seven states have no state income tax and therefore have no 1099 filing requirements:

  • Alaska
  • Florida
  • Nevada
  • South Dakota
  • Texas
  • Washington (has capital gains tax since 2022, but no general income tax)
  • Wyoming

For payees in these no-tax states, you only need to file with the IRS. There's no state copy requirement because the state doesn't tax the income being reported.

New Hampshire and Tennessee: New Hampshire only taxes interest and dividend income, so 1099 requirements are limited. Tennessee fully repealed its income tax (the Hall Tax) as of January 1, 2021, so it now has no 1099 filing requirements.

Verifying Current Participation Status

State participation in the CF/SF program can change from year to year as states join or adjust their requirements. While the list above reflects current participation, it's a good practice to verify participation status annually. You can confirm the current list of participating states by:

  • Checking IRS Publication 1220, which includes the official list of CF/SF participating states
  • Reviewing information from your 1099 filing software provider, which should maintain current participation data
  • Consulting with a tax professional who stays current on state filing requirements

Which 1099 Forms Are Covered by the CF/SF Program

Eligible Form Types

The Combined Federal State Filing Program covers the most common types of information returns that businesses need to file. The following 1099 form types are included in the CF/SF program:

  • Form 1099-NEC - Nonemployee Compensation (payments to independent contractors)
  • Form 1099-MISC - Miscellaneous Income (rent, royalties, prizes, awards, etc.)
  • Form 1099-INT - Interest Income
  • Form 1099-DIV - Dividends and Distributions
  • Form 1099-R - Distributions from Pensions, Annuities, Retirement Plans, IRAs, etc.
  • Form 1099-K - Payment Card and Third Party Network Transactions
  • Form 1099-G - Certain Government Payments
  • Form 1099-B - Proceeds from Broker and Barter Exchange Transactions
  • Form 1099-PATR - Taxable Distributions Received from Cooperatives
  • Form 1099-OID - Original Issue Discount
  • Form W-2G - Certain Gambling Winnings

For businesses, the most commonly used forms covered by CF/SF are 1099-NEC (for contractor payments), 1099-MISC (for rents, royalties, and other miscellaneous payments), and 1099-INT (for interest payments). Financial institutions frequently use 1099-DIV, 1099-INT, 1099-B, and 1099-OID.

Form-Specific Considerations

While all the forms above are eligible for CF/SF, there are practical considerations. 1099-NEC has a January 31 deadline for filing, while most other 1099 forms have a March 31 e-file deadline. Banks and financial institutions filing 1099-INT and 1099-DIV in high volume particularly benefit from CF/SF, as they may have account holders in all 50 states. While CF/SF handles the basic filing requirement, always verify state-specific rules for your particular form types.

Requirements for CF/SF Program Participation

Requirement 1: Electronic Filing

The most critical requirement for CF/SF participation is that you must e-file your 1099 forms. The CF/SF program only works with electronic filings submitted through authorized channels. If you paper-file your 1099s by mailing them to the IRS, your filing data will not be forwarded to participating states, and you'll need to file separately with each state.

This requirement is rarely a barrier because the IRS now mandates electronic filing for anyone submitting 10 or more information returns in a calendar year. The threshold was lowered from 250 forms starting in 2024, meaning that almost all businesses with multi-state payees are already required to e-file. The e-file mandate and CF/SF participation work hand-in-hand: if you're required to e-file, you can automatically benefit from CF/SF.

Electronic filing can be done through several authorized methods:

  • Third-party e-file providers like BoomTax, which handle the technical aspects of IRS submission
  • IRS IRIS (Information Returns Intake System), the IRS's free online filing portal for information returns
  • IRS FIRE system (Filing Information Returns Electronically), the legacy bulk filing system

Requirement 2: Include Complete State Information

For the IRS to forward your 1099 data to participating states, each form must include complete and accurate state information. The critical fields are:

State Code (Boxes 14/15): You must include the two-letter state abbreviation for the payee's state. This is typically the state where the payee resides (their mailing address state). Without this information, the IRS cannot determine which state should receive the data.

State Tax Withheld (Box 16): If you withheld any state income tax from payments to this payee, you must report the amount in this field. This is especially important because the payee needs this information to claim credit on their state tax return.

State ID Number (Box 17): Your state tax identification number for the payee's state. This helps the state match the filing to your business records.

State Income (Box 18): The income amount attributable to that state. This is usually the same as the federal amount unless specific sourcing rules apply.

If you leave the state code blank or enter invalid state information, the IRS cannot forward the data even if the payee is in a participating state. Double-check that every form includes the correct state code based on the payee's address.

Requirement 3: File by the Federal Deadline

To ensure that states receive your CF/SF data in time for their processing needs, you must file by the applicable federal deadline. The deadlines vary by form type:

  • Form 1099-NEC: January 31 (no extension available for paper or e-file)
  • Form 1099-MISC, 1099-DIV, 1099-INT, and most other 1099s: March 31 for electronic filing (February 28 for paper)

Filing late may mean states don't receive your data when they need it, potentially resulting in state-level compliance issues even if you filed federally. If you need additional time, you can file Form 8809 for an extension of up to 30 days, but extensions are not available for 1099-NEC. Forms filed under extension are still forwarded to states through CF/SF.

Requirement 4: Use an Authorized Filing Method

Your electronic filing must be submitted through an IRS-authorized method that supports CF/SF participation. The authorized methods include:

IRS-Authorized E-File Providers: Companies like BoomTax are authorized by the IRS to transmit information returns on your behalf. These providers automatically include CF/SF participation when you e-file 1099s, so there's nothing extra you need to do. The provider handles the technical formatting requirements.

IRS IRIS System: The IRS's free online filing portal (IRIS) supports CF/SF. When you file through IRIS, the state information you enter is included in the CF/SF data sharing.

FIRE System: The legacy Filing Information Returns Electronically system also supports CF/SF. However, FIRE requires specific technical knowledge to format files correctly and is being phased out in favor of IRIS.

The key is that whatever method you use must be capable of submitting state information to the IRS in the required format. All major authorized e-file providers support this automatically.

Step-by-Step Guide to Using the CF/SF Program

Step 1: Gather and Organize Your Payee Data

Before filing, compile all the information you need for each payee who will receive a 1099 form. Key information includes:

  • Payee name and address (exactly as it appears on their W-9)
  • Taxpayer Identification Number (TIN) - Social Security Number or EIN
  • Total payments for the year by category (nonemployee compensation, rent, interest, etc.)
  • State of residence based on their mailing address
  • Any state tax withheld and the state to which it applies

Having accurate, complete information from the start prevents errors that could affect both federal and state compliance. Use IRS TIN matching to verify that payee names and TINs are correct before filing.

Step 2: Categorize Payees by State Filing Method

Review your payee list and categorize each payee based on how their state filing will be handled:

  • CF/SF Participating States: These payees' filings will automatically be forwarded to their states through the CF/SF program. No additional action needed after federal filing.
  • New York: These payees require direct filing with New York State in addition to federal filing.
  • No-Tax States: Payees in Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming only need federal filing since their states don't have income tax requirements.

This categorization helps you plan your filing workflow and ensures you don't miss any required direct state filings.

Step 3: Prepare Your 1099 Forms with State Information

When entering data for each 1099 form, ensure you complete all state-related fields:

  • Enter the correct two-letter state code for the payee's state
  • Include your state tax ID number if required for that state
  • Enter any state tax withheld in the appropriate field
  • Specify the state income amount (usually same as federal unless sourcing rules apply)

Most 1099 filing software provides fields for up to two states per form. If a payee has income sourced to more than two states, you may need multiple forms.

Step 4: E-File Your 1099s with the IRS

Submit your federal 1099 filings electronically through your chosen authorized method. If you're using BoomTax:

  1. Upload your payee data via spreadsheet import or enter manually
  2. Review and verify all information, including state codes
  3. Run pre-filing validation to catch any errors
  4. Submit your e-filing
  5. Receive confirmation of IRS acceptance

When you e-file through an authorized provider like BoomTax, CF/SF participation is automatic. There's no separate checkbox or additional step required. The state information you included on your forms is automatically captured and will be forwarded to participating states.

Step 5: Complete Any Required Direct State Filings

After your federal e-filing is complete, address any states that require direct filing:

New York: Prepare and submit a separate filing with the New York State Department of Taxation and Finance. This typically requires:

  • Registering with New York's filing system if you haven't already
  • Formatting your data according to New York's specifications
  • Submitting electronically through New York's approved portal

For guidance on handling New York and other multi-state scenarios, see our complete guide on how to file 1099s with multiple states.

Step 6: Distribute Recipient Copies

Remember that you must provide 1099 copies to your payees by the applicable deadline (January 31 for 1099-NEC, March 31 for most other forms e-filed). This is a separate requirement from filing with the IRS and states. Options include:

  • Print and mail using a fulfillment service for convenience
  • Electronic delivery with proper recipient consent
  • Self-print and mail from downloaded PDFs

Step 7: Maintain Complete Records

Keep comprehensive records of all your filings for at least four years (the standard IRS retention requirement). Your records should include:

  • Copies of all 1099 forms filed
  • Federal e-file confirmation and acceptance acknowledgment
  • Documentation showing CF/SF participation
  • Any direct state filing confirmations (New York, etc.)
  • W-9 forms from all payees
  • Proof of recipient copy delivery

Common Mistakes That Prevent Successful CF/SF Participation

Mistake 1: Missing or Incorrect State Codes

The most common reason CF/SF participation fails is missing or incorrect state information on 1099 forms. If you leave the state code blank, or enter an invalid code, the IRS cannot determine which state should receive the data. Even if the payee is in a CF/SF participating state, they won't receive your filing if you didn't include their state code.

How to Avoid: Always verify that every 1099 form includes the correct two-letter state code based on the payee's mailing address. Use data validation in your filing software to catch missing state fields before submission.

Mistake 2: Paper Filing Instead of E-Filing

The CF/SF program only works with electronic filings. If you submit paper 1099 forms to the IRS, your data will not be forwarded to states. You would then need to file separately with each state that requires 1099 information.

How to Avoid: Always e-file your 1099 forms. This is now required by the IRS if you file 10 or more information returns, and it's the only way to participate in CF/SF. Even if you're under the 10-form threshold, e-filing for CF/SF benefits is worthwhile.

Mistake 3: Assuming All States Are Covered

While CF/SF covers most states, it doesn't cover all. The most significant gap is New York, which requires direct filing. Businesses that assume their federal e-filing covers all states may miss the New York requirement entirely.

How to Avoid: Review your payee list specifically for New York addresses and plan for direct New York filing. Also be aware of states without income tax where no state filing is needed at all.

Mistake 4: Not Reporting State Withholding Properly

If you withheld state income tax from payments, that withholding must be reported on the 1099 form. Failing to report withholding means the payee won't have documentation to claim credit for taxes already paid when they file their state return.

How to Avoid: Maintain careful records of all state withholding throughout the year. When preparing 1099s, ensure Box 16 (State tax withheld) accurately reflects any amounts withheld for the state indicated in Boxes 14/15.

Mistake 5: Filing After the Deadline

While CF/SF still works for late filings, filing after the federal deadline can result in penalties at both the federal and state level. States may also have processing windows where late-forwarded data creates issues.

How to Avoid: Mark deadlines on your calendar and begin preparation well in advance. For 1099-NEC, the deadline is January 31 with no extensions. For other forms, file by March 31 (e-file) to avoid penalties.

Mistake 6: Forgetting to Update Payee Information

If a payee moved to a different state during the year, using outdated address information means the 1099 may be forwarded to the wrong state. The payee's new state may not receive the filing, creating compliance issues.

How to Avoid: Collect updated W-9 forms from payees at least annually, especially at year-end before preparing 1099s. Verify addresses are current before filing.

How Corrections Work with the CF/SF Program

Filing Corrected 1099s Through CF/SF

If you discover an error on a 1099 form after filing, you can file a corrected return. The good news is that corrections filed electronically with the IRS are also forwarded to CF/SF participating states just like original filings. The same data sharing mechanism applies.

When you file a correction:

  • The corrected 1099 is submitted to the IRS with a correction indicator
  • The IRS processes the correction and updates their records
  • For CF/SF participating states, the corrected data is forwarded to replace the original
  • The state receives the updated information automatically

Corrections for Non-CF/SF States

For states that don't participate in CF/SF (primarily New York), you must file corrections directly with the state in addition to filing with the IRS. The correction must be submitted through the state's filing system using their specific correction procedures.

Types of Corrections and Voids

There are two types of 1099 corrections: Type 1 corrections fix errors in payee name, TIN, or address; Type 2 corrections fix dollar amount errors. Both types flow through CF/SF when e-filed. If you filed a 1099 in error (wrong payee, duplicate), you can file a void, which is also transmitted through CF/SF to notify states.

Real-World Examples of CF/SF in Action

Example 1: Small Business with Contractors in Multiple States

Scenario: A marketing consultancy in Colorado pays 25 contractors located across 12 different states, including California, Texas, Illinois, and Georgia.

CF/SF Application:

  • The business prepares 1099-NEC forms for all 25 contractors with complete state information
  • E-files with the IRS through BoomTax
  • California, Illinois, Georgia, and 8 other states receive data automatically through CF/SF
  • Texas contractors require federal-only filing (no state income tax)
  • Result: One federal e-filing satisfies obligations for 11 states plus federal

Example 2: Financial Institution with Account Holders Nationwide

Scenario: A regional credit union has members in all 50 states and needs to file 1099-INT forms for interest paid on savings accounts exceeding $10.

CF/SF Application:

  • The credit union uses bulk upload to prepare thousands of 1099-INT forms
  • E-files all forms with the IRS, including state codes for each account holder
  • 40+ participating states receive data automatically
  • New York members require direct state filing (1,200 forms)
  • Members in no-tax states (FL, TX, etc.) need only federal filing
  • Result: One bulk federal filing plus one New York direct filing covers nationwide compliance

Example 3: Accounting Firm Filing for Multiple Clients

Scenario: A CPA firm handles 1099 filings for 40 business clients, representing over 500 total payees in various states.

CF/SF Application:

  • Uses a multi-company platform like BoomTax to manage all clients under one account
  • Prepares 1099s for each client with proper state information
  • E-files all forms, with CF/SF automatically handling most state requirements
  • Compiles New York payees across all clients for single direct NY filing
  • Result: Centralized compliance for 40 clients with minimal state-specific overhead

Frequently Asked Questions About the Combined Federal State 1099 Program

What is the Combined Federal State Filing Program for 1099s?

The Combined Federal State Filing Program (CF/SF) is an IRS initiative that simplifies 1099 compliance by automatically sharing your federal e-filing data with participating state tax agencies. When you e-file 1099 forms with the IRS and include state information, the IRS forwards the data to over 40 participating states. This eliminates the need to file separately with most states, saving time and reducing compliance complexity. The program covers common 1099 form types including 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, and others.

Is there a fee for participating in the CF/SF program?

No, there is no additional fee from the IRS for CF/SF participation. The data forwarding to states is included as part of your federal e-filing at no extra charge. If you use an authorized e-file provider like BoomTax, CF/SF participation is built into the standard filing service. You pay for your federal e-filing, and state compliance for participating states is automatically included.

Do I need to register with each state to use CF/SF?

No, you do not need to register separately with each participating state. The IRS handles the data transmission to states, and your federal e-filing submission serves as your interaction point. However, you should have state tax ID numbers where applicable, as some states require this information on the 1099 form. For non-participating states like New York that require direct filing, you may need to register with that state's tax department.

Which states don't participate in the CF/SF program?

The primary non-participating state is New York, which requires direct filing with the New York State Department of Taxation and Finance. Additionally, seven states have no income tax and therefore have no 1099 filing requirements: Alaska, Florida, Nevada, South Dakota, Texas, Washington (has capital gains tax but no general income tax), and Wyoming. For payees in these no-tax states, only federal filing is required.

What happens if I paper-file instead of e-file?

If you paper-file your 1099 forms with the IRS, your data will not be forwarded to states through the CF/SF program. You would need to file separately with each state that requires 1099 information. Since the IRS requires electronic filing for anyone submitting 10 or more information returns, most businesses with multi-state payees will be e-filing anyway. E-filing is strongly recommended to take advantage of CF/SF benefits.

How do I know if my CF/SF filing was successful?

When you e-file through an authorized provider like BoomTax, you receive confirmation that the IRS accepted your filing. CF/SF data transmission happens automatically after IRS acceptance. While you won't receive separate confirmation from each state, successful federal acceptance with proper state codes means participating states will receive your data. If you have concerns about a specific state, you can contact that state's tax agency to verify receipt.

Can I use CF/SF for corrected 1099 forms?

Yes. When you e-file corrected 1099 forms with the IRS, the corrections are forwarded to CF/SF participating states just like original filings. The same data sharing mechanism applies. For states requiring direct filing (like New York), you must also file corrections directly with that state.

What if my payee moved to a different state during the year?

Use the payee's current address (at the time of filing) on the 1099 form. The state code should reflect where they currently reside. If they moved from a CF/SF state to another CF/SF state, the filing will be forwarded to their new state. If they moved to or from New York, adjust your filing approach accordingly. If they moved to a no-tax state, only federal filing is needed.

Does CF/SF cover state tax withholding reporting?

Yes. When you include state tax withheld amounts in Box 16 of the 1099, this information is forwarded to the appropriate state through CF/SF. This is important because it allows payees to claim credit for state taxes you already withheld when they file their state income tax returns. Accurate withholding reporting is essential for your payees' tax compliance.

How does CF/SF work with multi-state income?

If a payee earned income in multiple states, you may need to report this appropriately. The 1099 form accommodates up to two states. For more complex multi-state situations, you may need multiple forms. Each state's portion of income will be forwarded through CF/SF to that state. For detailed guidance, see our article on filing 1099s with multiple states.

Are there deadlines specific to CF/SF participation?

CF/SF follows the standard federal e-filing deadlines. For 1099-NEC, the deadline is January 31. For other 1099 forms filed electronically, the deadline is March 31. Meeting the federal deadline ensures timely forwarding to states. There are no separate CF/SF deadlines to track.

What if I accidentally omitted state information on some forms?

If you e-filed without state codes on some forms, those forms won't be forwarded to states through CF/SF even if the payee is in a participating state. You may need to file corrected forms with the state information added, or file directly with the affected states. To avoid this, always verify that state codes are complete before submitting your federal e-filing.

Conclusion: Maximizing the Benefits of the CF/SF Program

The Combined Federal State Filing Program for 1099s is one of the most valuable compliance tools available to businesses filing information returns. By allowing your federal e-filing to simultaneously satisfy state requirements for over 40 participating states, CF/SF dramatically reduces the complexity, time, and cost of multi-state 1099 compliance.

To successfully leverage the combined federal state 1099 program, remember these key points:

  • Always e-file your 1099 forms to participate in CF/SF (paper filing doesn't qualify)
  • Include complete state information on every form, especially the two-letter state code
  • Verify your payee list for New York addresses that require separate direct filing
  • Meet federal deadlines to ensure timely forwarding to states
  • Use authorized e-file providers like BoomTax that automatically include CF/SF participation
  • Maintain good records of your filings for future reference
  • File corrections electronically to ensure states receive updated information

The CF/SF program transforms what could be dozens of separate filing obligations into a single, streamlined process. Whether you're a small business with contractors in a few states or an enterprise with payees nationwide, CF/SF makes compliance manageable.
