Complete Guide to Colorado 1099 Filing Requirements for 2026

Introduction: Understanding Colorado 1099 Filing Obligations

If you operate a business in Colorado or pay contractors who reside in the Centennial State, understanding Colorado 1099 filing requirements is essential for maintaining tax compliance. Colorado has specific state tax reporting requirements that work alongside federal obligations, and failing to meet these requirements can result in penalties, back taxes, and potential audits from the Colorado Department of Revenue (DOR).

Colorado's 1099 filing requirements are designed to ensure that all income paid to Colorado residents or for Colorado-source work is properly reported to state tax authorities. While the IRS requires businesses to report payments to contractors and other non-employees through various 1099 forms, Colorado adds its own layer of requirements through the DOR. The state participates in the IRS Combined Federal/State Filing (CF/SF) program, which simplifies compliance for many businesses by automatically sharing federal 1099 data with the state.

The stakes for proper compliance in Colorado are significant. As one of the fastest-growing states in the nation with a thriving economy centered around technology, aerospace, outdoor recreation, and energy industries, Colorado has a large and diverse workforce that includes many independent contractors. The Colorado Department of Revenue actively monitors 1099 filings to ensure income tax compliance, and businesses that fail to file required information returns may face penalties and additional scrutiny.

Colorado's growing gig economy and the prevalence of remote work have made 1099 filing even more important. Many businesses based outside Colorado now have contractors working from within the state, creating filing obligations that business owners may not immediately recognize. Whether you're a Colorado-based business paying local contractors or an out-of-state company with Colorado workers, understanding your filing requirements is crucial.

This comprehensive guide covers everything you need to know about Colorado 1099 filing requirements, including:

  • Which 1099 forms Colorado requires and when they must be filed
  • Colorado-specific thresholds and reporting rules
  • How the Combined Federal/State Filing Program works for Colorado
  • Colorado withholding requirements and rates
  • DOR penalties for non-compliance with 1099 filing
  • Step-by-step instructions for filing 1099s with Colorado
  • Special considerations for nonresident contractors
  • How to correct errors on Colorado 1099 filings

Colorado 1099 Filing Requirements: The Basics

Who Must File 1099s in Colorado?

Colorado requires businesses and individuals to file 1099 information returns with the Department of Revenue when they make certain payments to Colorado residents or for Colorado-source income. The fundamental rule aligns with federal requirements: if you're required to file a 1099 with the IRS for a payee in Colorado, you must also ensure that information reaches the Colorado DOR.

Specifically, you must file 1099s with Colorado if you:

  • Pay Colorado residents amounts that meet IRS reporting thresholds
  • Make payments for services performed in Colorado, regardless of where the payee resides
  • Withheld Colorado state income tax from any payments
  • Have Colorado-source income to report, such as rent from Colorado property or royalties from Colorado resources
  • Operate a business in Colorado that makes reportable payments to contractors or vendors

This applies to all types of business entities including sole proprietors, partnerships, limited liability companies (LLCs), S corporations, and C corporations. Even out-of-state businesses must file Colorado 1099s if they pay Colorado residents or for Colorado-source income. The growing trend of remote work has expanded these obligations significantly, as many workers now perform services from Colorado for companies located elsewhere.

Colorado's income tax structure is unique in that it uses a flat tax rate (currently 4.4% for 2024, reduced from previous years due to TABOR refunds). This means that every dollar of taxable income reported on 1099s directly impacts state revenue, making accurate reporting particularly important to the DOR.

Types of 1099 Forms Required by Colorado

Colorado requires reporting for virtually all IRS 1099 form types. The state follows federal reporting requirements, meaning any form filed with the IRS should also be reported to Colorado if it involves Colorado payees or Colorado-source income. The most common forms filed with the DOR include:

Form Type What It Reports Colorado Threshold
1099-NEC Nonemployee compensation to contractors $600 or more
1099-MISC Rent, royalties, prizes, and other income $600+ (most categories); $10+ for royalties
1099-INT Interest income $10 or more
1099-DIV Dividend payments $10 or more
1099-R Retirement distributions $10 or more
1099-K Payment card and third-party transactions Federal threshold applies
1099-G Government payments, unemployment $10 or more
1099-B Broker transactions All reportable transactions
1099-S Real estate transactions Gross proceeds from sales

Important: Colorado generally follows federal thresholds, but any form showing Colorado state tax withheld must be filed with the DOR regardless of the payment amount. This ensures payees can claim credit for withholding on their Colorado tax returns. Additionally, Colorado may require reporting for certain payments that don't have federal withholding but do have Colorado withholding.

Colorado Filing Deadlines for 1099 Forms

Colorado aligns its 1099 filing deadlines with federal deadlines. Understanding these deadlines is crucial for avoiding penalties:

Form Type Recipient Copy Deadline DOR/IRS Filing Deadline
1099-NEC January 31 January 31
1099-MISC January 31 March 31 (e-file) / February 28 (paper)
1099-INT January 31 March 31 (e-file) / February 28 (paper)
1099-DIV January 31 March 31 (e-file) / February 28 (paper)
1099-R January 31 March 31 (e-file) / February 28 (paper)

The 1099-NEC deadline of January 31 is particularly strict because it applies to both filing with the IRS/DOR and furnishing copies to recipients. This accelerated deadline exists because 1099-NEC reports contractor income that tax authorities want to verify early in the tax season to detect and prevent fraud. Missing this deadline triggers immediate penalty exposure.

Colorado businesses should note that when deadlines fall on weekends or holidays, the deadline shifts to the next business day. It's always best to file early to avoid last-minute technical issues or processing delays that could result in late filing penalties.

The Combined Federal/State Filing Program for Colorado

How CF/SF Works with Colorado

Colorado participates in the IRS Combined Federal/State Filing (CF/SF) program, which significantly simplifies state 1099 filing for businesses. When you e-file your 1099 forms with the IRS and participate in the CF/SF program, the IRS automatically forwards your filing data to the Colorado Department of Revenue.

The benefits of CF/SF for Colorado filers include:

  • Single filing satisfies both federal and Colorado requirements - no need to file separately with the DOR
  • No separate submission to the DOR needed for most 1099 forms
  • Consistent data between IRS and DOR records reduces discrepancies
  • Reduced administrative burden and compliance costs for businesses
  • Automatic processing without additional manual steps
  • Faster data transmission to state authorities

Important: The CF/SF program only applies to electronic filings. If you paper-file your 1099s with the IRS, you must submit separate copies to the Colorado DOR. This is one of many reasons why electronic filing is strongly recommended for all businesses, especially those with Colorado filing obligations.

Participating in CF/SF for Colorado Filing

To ensure your Colorado 1099 filing is handled through the CF/SF program, follow these steps:

  1. Prepare your 1099 forms with complete and accurate information for all payees
  2. Include Colorado state information in the appropriate boxes:
    • Box 14/15: Your Colorado employer identification number or Colorado account number
    • Box 16: Colorado state tax withheld (if any)
    • Box 17: State abbreviation (CO) and payer's state number
    • Box 18: State income amount
  3. Enter the Colorado state code (CO) on all forms for Colorado payees
  4. E-file your 1099 forms with the IRS through an authorized e-file provider
  5. Select CF/SF participation during the e-file submission process
  6. Retain confirmation of your submission for your records

When using BoomTax, Colorado CF/SF participation is handled automatically. Simply enter the state information on your forms, and BoomTax ensures proper formatting and transmission to both the IRS and Colorado through the CF/SF program. This eliminates the complexity of managing separate state filings.

When Direct Colorado Filing May Be Required

While the CF/SF program covers most situations, there are cases where you may need to file directly with the Colorado DOR:

  • Paper filings: If you paper-file with the IRS, CF/SF doesn't apply and you need separate DOR submission
  • Certain corrections: Some corrected forms may require direct DOR submission depending on timing
  • Late filings: If you miss the CF/SF window, direct filing may be necessary
  • Colorado-only withholding: If you have Colorado withholding without federal withholding, direct reporting may be required
  • Specific form types: Certain specialized forms may not be covered by CF/SF

For direct Colorado filings, the DOR accepts electronic submissions through their online Revenue Online portal or through approved software providers. The DOR's online system allows businesses to upload wage and information return data directly when CF/SF is not an option.

Colorado Withholding Requirements for 1099 Payments

What is Colorado Withholding for Non-Employees?

Colorado requires payers to withhold state income tax from certain payments made to non-employees, including independent contractors. This withholding requirement operates alongside federal backup withholding requirements but is specific to Colorado state income tax.

Colorado withholding for non-employees applies when:

  • Payments exceed certain thresholds to Colorado residents
  • Nonresident contractors perform services in Colorado
  • Colorado-source income is paid to any payee
  • Backup withholding situations exist at the federal level

Colorado Withholding Rates

Colorado's current income tax rate is 4.4% (for tax year 2024). This flat rate applies to all taxable income, including amounts that may be subject to withholding from non-employee compensation. When Colorado withholding is required, you must:

  • Withhold at the Colorado rate (currently 4.4%) from applicable payments
  • Deposit withholdings with the Colorado DOR according to your deposit schedule
  • Report withholdings on Form 1099 in Box 16
  • File required withholding returns with the DOR

Example: You pay a Colorado contractor $10,000 for services, and Colorado withholding applies. You must withhold:

  • Colorado state withholding: $440 (4.4% of $10,000)
  • Payment to contractor: $9,560

If federal backup withholding (currently 24%) also applies, the total withholding would be $2,840 ($2,400 federal + $440 Colorado), with a net payment of $7,160 to the contractor.

Nonresident Contractor Withholding

Colorado has specific rules for payments to nonresident contractors who perform services in Colorado. When you pay a nonresident for work performed within Colorado, you may be required to withhold Colorado income tax even though the payee is not a Colorado resident.

Key considerations for nonresident withholding:

  • Colorado-source income from services performed in Colorado is subject to Colorado tax
  • Withholding may be required based on the amount and nature of payments
  • The nonresident must file a Colorado return to claim credit for withholding or get a refund
  • Proper documentation of where services were performed is essential

When withholding from nonresidents, report the withheld amounts in Box 16 of the 1099 and ensure the Colorado state information is complete in Boxes 17 and 18.

Reporting Colorado Withholding on 1099 Forms

When you withhold Colorado state tax, you must report it properly on the 1099 form:

  • Box 16: Enter the total Colorado state tax withheld
  • Box 17: Enter "CO" as the state abbreviation along with your Colorado account number
  • Box 18: Enter the state income amount (usually the same as the federal amount unless only part of the income is Colorado-source)

You must also deposit the withheld taxes with the Colorado DOR according to your assigned deposit schedule and file any required quarterly or annual withholding returns. Proper documentation and timely deposits are essential to avoid penalties and interest charges.

Colorado Penalties for 1099 Non-Compliance

DOR Penalty Structure

Colorado imposes its own penalties for failing to file 1099s or filing late, separate from federal penalties. Understanding these penalties helps emphasize the importance of timely and accurate filing:

Violation Penalty Notes
Failure to file timely $50 per form (state) + federal penalties Applies to each information return filed late
Failure to file correct information $50 per form Incorrect TIN, name, amounts, etc.
Failure to furnish payee statement $50 per statement Not providing copy to recipient by deadline
Intentional disregard Greater of $100 per form or 10% of amount Willful failure to comply
Withholding violations Amount not withheld plus interest and penalties Failure to withhold when required

Combined Federal and Colorado Penalties

Remember that federal and Colorado penalties are separate and cumulative. If you fail to file a 1099-NEC for a Colorado contractor, you could face:

  • Federal penalty: Up to $310 per form (for 2025) for late filing, scaling up to $630 for intentional disregard
  • Colorado penalty: Additional state penalties as outlined above
  • Total potential penalty: $360+ per form for a single late filing violation

For businesses with many contractors, these penalties can quickly reach thousands of dollars. A company with 50 Colorado contractors who fails to file 1099-NEC forms on time could face over $18,000 in combined federal and state penalties. To avoid 1099 penalties, file accurately and on time with both the IRS and Colorado.

Penalty Abatement and Waivers

In some cases, the Colorado DOR may waive or reduce penalties:

  • Reasonable cause: Penalties may be waived if you can demonstrate reasonable cause for the failure
  • First-time abatement: Colorado may offer first-time penalty relief for eligible taxpayers with clean compliance history
  • Timely correction: Penalties may be reduced if you correct errors within certain timeframes
  • De minimis errors: Minor errors that don't affect the payee's tax liability may not trigger penalties
  • Good faith effort: Evidence of good-faith compliance efforts may support penalty relief

Documentation is key for penalty abatement requests. Keep records of your compliance efforts, any circumstances that led to late or incorrect filings, and communications with the DOR. The better documented your case, the more likely you are to receive penalty relief.

Worker Classification in Colorado

Colorado's Approach to Worker Classification

Proper worker classification is crucial before filing 1099s in Colorado. Misclassifying employees as independent contractors can result in significant penalties, back taxes, and legal liability. Colorado uses criteria similar to the IRS for determining whether a worker is an employee or an independent contractor.

The key factors Colorado considers include:

  • Behavioral control: Does the company control or have the right to control what the worker does and how they do their job?
  • Financial control: Does the business control the financial aspects of the worker's job, including how they are paid, whether expenses are reimbursed, and who provides tools and supplies?
  • Type of relationship: Are there written contracts or employee-type benefits? Is the relationship permanent? Are the services performed a key aspect of the business?

1099 Filing Implications of Misclassification

If you issue a 1099 to someone who should have been classified as an employee, you may face:

  • Reclassification by the DOR: Colorado can reclassify workers and assess back employment taxes
  • Unpaid employment taxes: Including Social Security, Medicare, unemployment, and workers' compensation
  • Back wages and benefits: Workers may be entitled to minimum wage, overtime, and benefits they would have received as employees
  • Legal liability: Private lawsuits and class actions for misclassification
  • Incorrect 1099 penalties: Filing a 1099 when a W-2 was required triggers additional compliance issues

Before filing 1099s for Colorado workers, carefully evaluate each relationship against the classification criteria. When in doubt, consult with a qualified employment attorney or tax professional familiar with Colorado law.

Colorado-Specific Classification Considerations

Colorado has become increasingly active in worker classification enforcement. The Colorado Division of Labor Standards and Statistics monitors classification practices, and the state has taken action against businesses that systematically misclassify workers. Industries with high rates of contractor use, such as construction, gig economy, and professional services, receive particular scrutiny.

Best practices for Colorado businesses include:

  • Document the relationship with written contracts that accurately reflect the working arrangement
  • Maintain consistency between how you treat and pay workers and how you classify them
  • Conduct periodic reviews of contractor relationships to ensure ongoing compliance
  • Consult professionals when classification is unclear

Step-by-Step Guide to Colorado 1099 Filing

Step 1: Gather Payee Information

Start by collecting complete and accurate information for each Colorado payee:

  1. Obtain Form W-9 from each contractor before making payments
  2. Verify the information provided:
    • Legal name (must match IRS records)
    • Business name (if different from legal name)
    • Current address (Colorado address for Colorado residents)
    • Tax Identification Number (SSN or EIN)
    • Tax classification (individual, LLC, corporation, etc.)
  3. Use TIN matching to verify the TIN/name combination with the IRS
  4. Request updated W-9s if information changes during the year

Proper W-9 collection is the foundation of accurate 1099 filing. Without correct payee information, you risk filing errors, rejected returns, and potential penalties.

Step 2: Calculate Payment Totals

Total all reportable payments made to each payee during the calendar year:

  • Review all payment records for accuracy and completeness
  • Include all payment methods: checks, ACH, wire transfers, cash (note: credit card payments reported on 1099-K are generally excluded from 1099-NEC/MISC)
  • Separate payments by category: nonemployee compensation, rent, royalties, etc.
  • Calculate Colorado income: For Colorado payees, state income usually equals the total payment unless only part is Colorado-source
  • Track any withholding collected during the year, including both federal and Colorado amounts

Step 3: Prepare 1099 Forms with Colorado Information

For each Colorado payee meeting filing thresholds:

  1. Select the correct form type (1099-NEC, 1099-MISC, etc.) based on the type of payment
  2. Enter federal information in Boxes 1-13 as required for the specific form
  3. Complete Colorado state boxes:
    • Box 14/15: Your Colorado account number
    • Box 16: Colorado state tax withheld (if any)
    • Box 17: CO and state payer number
    • Box 18: State income amount
  4. Verify all entries before finalizing to catch errors early

Step 4: E-File with CF/SF Participation

Submit your Colorado 1099s through electronic filing:

  1. Use an IRS-authorized e-file provider like BoomTax
  2. Upload or enter your 1099 data following the provider's instructions
  3. Ensure Colorado state information is complete on all forms for Colorado payees
  4. Select CF/SF program participation to automatically share data with Colorado
  5. Submit your e-filing before the deadline
  6. Retain confirmation of successful submission for your records

BoomTax automatically handles CF/SF formatting and submission, ensuring your Colorado forms reach the DOR through the IRS data sharing program. This eliminates the complexity of managing separate state filings and reduces the risk of errors.

Step 5: Furnish Copies to Recipients

By January 31, provide Copy B of each 1099 to the recipient:

  • Mail recipient copies to their last known address, or
  • Deliver electronically if the recipient has consented to e-delivery
  • Include any applicable state copies showing Colorado information
  • Retain proof of mailing or delivery in case of disputes

For bulk filings, BoomTax offers print and mail services to handle recipient copy distribution for you, ensuring timely delivery and reducing administrative burden.

Step 6: Maintain Records

Keep complete records of your Colorado 1099 filings for at least four years:

  • Copies of all filed 1099 forms
  • W-9 forms from all payees
  • Payment records and documentation
  • E-file confirmations and acknowledgments
  • Proof of recipient copy delivery
  • Correspondence related to withholding
  • Any corrections filed

Correcting Errors on Colorado 1099 Filings

When Corrections Are Needed

If you discover errors on previously filed Colorado 1099s, you must file corrections. Common situations requiring corrections include:

  • Incorrect payment amount
  • Wrong payee name or TIN
  • Missing or incorrect state information
  • Filing for the wrong payee
  • Duplicate filings
  • Incorrect withholding amounts

Correction Process for Colorado

Corrections filed through the CF/SF program are automatically shared with Colorado. To file a correction:

  1. Determine the correction type:
    • Type 1: Dollar amount only (one-step correction)
    • Type 2: Name, TIN, or other identifying information change (two-step correction)
  2. Prepare the corrected form with the CORRECTED box checked
  3. E-file the correction through your e-file provider
  4. Furnish corrected copy to the recipient
  5. Document the correction in your records

BoomTax includes unlimited corrections at no additional charge, making it easy to fix errors without incurring extra costs. The correction flows through CF/SF to Colorado automatically.

Special Situations for Colorado 1099 Filing

Out-of-State Businesses with Colorado Payees

If your business is located outside Colorado but you pay Colorado residents or make payments for Colorado-source income, you still have Colorado 1099 filing obligations:

  • File 1099s for Colorado resident payees when payment thresholds are met
  • Use the CF/SF program through your federal e-filing
  • Include Colorado state boxes on forms for Colorado payees
  • Report Colorado-source income (like rent from Colorado property or services performed in Colorado) even for non-resident payees

The growth of remote work has made this situation increasingly common. Many Colorado residents now work for out-of-state companies, and those companies have reporting obligations to Colorado.

Colorado Businesses with Out-of-State Payees

Colorado-based businesses paying contractors in other states must file with the appropriate states:

  • File with Colorado for any Colorado resident payees
  • File with other states based on their requirements (see state filing requirements)
  • Use CF/SF program for states that participate
  • No state filing needed for states without income tax (Alaska, Florida, Nevada, South Dakota, Texas, Washington, Wyoming)

For guidance on filing 1099s with multiple states, see our comprehensive multi-state filing guide.

Marijuana Industry Considerations

Colorado's legal marijuana industry presents unique 1099 filing considerations. While marijuana remains illegal at the federal level, Colorado-licensed cannabis businesses must comply with state tax reporting requirements:

  • File 1099s for contractors providing services to cannabis businesses
  • Maintain proper documentation of all payments and services
  • Consult with tax professionals familiar with the unique compliance requirements of the cannabis industry
  • Be aware of federal limitations on deductions and credits that may affect overall tax planning

Oil and Gas Industry Considerations

Colorado's significant oil and gas industry has specific 1099 reporting considerations:

  • Royalty payments to mineral rights holders must be reported on 1099-MISC
  • Contractor payments for drilling, extraction, and related services require 1099-NEC
  • Special sourcing rules may apply for payments related to Colorado resources
  • Proper identification of Colorado-source income is essential

Frequently Asked Questions About Colorado 1099 Filing

Does Colorado require me to file 1099s with the state?

Yes, Colorado requires 1099 filing with the Department of Revenue (DOR) for payments made to Colorado residents or for Colorado-source income. However, Colorado participates in the IRS Combined Federal/State Filing (CF/SF) program, so when you e-file your 1099s with the IRS and participate in CF/SF, your data is automatically forwarded to the DOR. You don't need to file separately with Colorado if you e-file federally with CF/SF participation.

What is the Colorado 1099 filing deadline?

Colorado follows federal deadlines. For 1099-NEC, both the IRS/DOR filing deadline and the recipient copy deadline is January 31. For most other 1099 forms (1099-MISC, 1099-INT, 1099-DIV, etc.), the e-file deadline is March 31, and the recipient copy deadline is January 31. Paper filing deadlines are earlier (February 28), but electronic filing is strongly recommended.

What is Colorado's income tax rate for withholding purposes?

Colorado's current income tax rate is 4.4% (for tax year 2024). This flat rate applies to all taxable income and is used when Colorado withholding from non-employee compensation is required. The rate has been reduced in recent years due to TABOR (Taxpayer's Bill of Rights) refund requirements.

What are Colorado's penalties for not filing 1099s?

Colorado imposes penalties for failure to file timely or failure to file correct information. These state penalties are separate from and in addition to federal penalties. The combined federal and state penalties can quickly accumulate, especially for businesses with many contractors. Filing accurately and on time is essential to avoid these costs.

Do I need to file 1099s with Colorado if I'm an out-of-state business?

Yes, if you pay Colorado residents or make payments for Colorado-source income (such as rent for Colorado property or services performed in Colorado), you must report those payments to Colorado. Use the CF/SF program through your federal e-filing to automatically share data with Colorado. Include Colorado state information in the state boxes on forms for Colorado payees.

How does Colorado handle worker classification?

Colorado uses criteria similar to the IRS for determining whether a worker is an employee or independent contractor, examining behavioral control, financial control, and the type of relationship. Misclassifying employees as contractors can result in penalties, back taxes, and legal liability. Always evaluate worker relationships carefully before issuing 1099s.

What forms does Colorado require?

Colorado requires the same 1099 forms as the IRS, including 1099-NEC (nonemployee compensation), 1099-MISC (rents, royalties, other income), 1099-INT (interest), 1099-DIV (dividends), 1099-R (retirement distributions), 1099-K (payment card transactions), 1099-S (real estate), and 1099-B (broker transactions). Any form with Colorado state tax withheld must be filed regardless of payment amount.

How do I correct a Colorado 1099 that was filed incorrectly?

File a corrected 1099 with the IRS using the same e-file process. Check the CORRECTED box on the form and submit through your e-file provider. If you're using the CF/SF program, the correction will automatically be shared with Colorado. Furnish a corrected copy to the recipient as well. BoomTax includes unlimited corrections at no additional charge.

What Colorado account number do I use on 1099 forms?

Use your Colorado Department of Revenue account number or your federal EIN registered with Colorado. This goes in Box 14/15 of the 1099 form along with "CO" as the state abbreviation in Box 17. If you haven't registered with Colorado but have Colorado filing obligations, you may need to register with the DOR to obtain appropriate credentials.

Does Colorado accept paper 1099 filings?

While Colorado technically accepts paper filings, the CF/SF program that automates Colorado filing only works with electronic submissions. If you paper-file with the IRS, you must also submit separate paper copies to the DOR. Given the efficiency of e-filing and the automatic Colorado compliance through CF/SF, electronic filing is strongly recommended for all businesses.

What if I miss the Colorado 1099 filing deadline?

File as soon as possible to minimize penalties. Colorado imposes penalties for late filing, and federal penalties also apply. The sooner you file after the deadline, the better your position. If you had reasonable cause for the delay, you may be able to request penalty abatement from the DOR. Document any circumstances that caused the delay and be prepared to explain them.

Do I need to file 1099s for payments made by credit card?

Generally no. Payments made by credit card, debit card, or through third-party payment networks like PayPal are reported by the payment processor on Form 1099-K, not by you. However, you must still file 1099-NEC or 1099-MISC for payments made by check, ACH, wire transfer, cash, or other non-card methods. Keep good records of payment methods to ensure accurate reporting.

Conclusion: Mastering Colorado 1099 Filing Compliance

Understanding and meeting Colorado 1099 filing requirements is essential for any business that pays contractors, freelancers, or makes other reportable payments to Colorado residents or for Colorado-source income.
