Iowa 1099-MISC Filing Requirements, Tax Year 2026
What Iowa requires from businesses filing 1099-MISC (Miscellaneous information) for tax year 2026: deadline, accepted format, CF/SF treatment, registration, and penalties, backed by primary-source citations.
Filing requirements
Iowa does not require a separate state filing of 1099-MISC for tax year 2026. Federal filing satisfies the reporting obligation; no state submission is required.
Iowa requires 1099-MISC to be filed with the Department only when Iowa income tax was withheld on the payment. Without Iowa withholding there is no Iowa filing obligation (Iowa does not participate in CF/SF). When Iowa tax was withheld, the form must be filed directly through GovConnectIowa by February 15.
Deadlines and extensions
Extensions
Not applicable. Because 1099-MISC is not required to be filed with Iowa, there is no state extension process.
Accepted format
No state filing is required for 1099-MISC in Iowa, so no state-specific format applies.
Registration
Registration required: Yes
Late-filing penalties
Iowa penalty overview
HF 2552 civil penalty: $500 per occurrence for willful failure to file or furnish a W-2 / 1099, willfully filing a false or fraudulent statement, or willfully filing late. Calculated per payee for furnishing failures (e.g., 10 missing payee copies = $5,000). Filing failures with the Department aggregate to a single $500 penalty per filing event. Codified at Iowa Code section 422.16(10). A 30-day extension may be granted on application before the February 15 deadline.

Source citations
“If businesses did not withhold any Iowa taxes in 2025, filing is not required.”
“If I have 60 employees, but only 10 of them have Iowa withholding tax, am I required to file for all my employees? No. You're only required to electronically file the 10 W-2 / 1099 forms that contain Iowa withholding tax.”
“For tax year 2019 and all subsequent tax years, all payers are required to electronically file all W-2 forms, W-2G forms, and 1099 forms for payees from whom Iowa income tax was withheld with the department of revenue on or before February 15 following the tax year.”
Additional notes
Iowa requires direct electronic filing of W-2 and 1099 information returns through GovConnectIowa. Iowa is not a participant in the IRS Combined Federal/State Filing Program (CF/SF), so federal-only filing never satisfies Iowa's requirement. The filing obligation is withholding-triggered: only forms that contain Iowa income tax withholding must be electronically filed with the Department. If a payer did not withhold any Iowa tax during the year, no W-2/1099 filing with Iowa is required. The deadline is February 15 following the tax year. Iowa does not accept paper W-2s or 1099s. The 1099 file format follows IRS Publication 1220 with Iowa-specific record adjustments documented by the Department.
Scope: Original 1099 filings with no Iowa state income tax withheld. State agencies revise rules without notice; verify with the Iowa state agency directly before you file.
