Filing requirements

Federal filing through the IRS Combined Federal/State Filing (CF/SF) Program satisfies California's 1099-MISC reporting requirement for tax year 2026. No separate state submission is required when the IRS forwards the record to California under CF/SF.

California participates in the IRS Combined Federal/State Filing Program for 1099-MISC. E-filing 1099-MISC with the IRS via FIRE/IRIS under Publication 1220 satisfies California's filing requirement when federal and California amounts match. Direct filing via SWIFT is required for state-only differences.

Conditional rules

Specific scenarios that change the baseline requirement above:

ConditionExplanation
Direct filing required when federal and California amounts differ

If you have an exception that requires you to report something different for federal and state purposes (for example, a different dollar amount), file separate returns with the IRS and FTB via SWIFT.

Deadlines and extensions

Federal e-file deadline
Holiday/weekend rollover. If the deadline falls on a weekend or a federal holiday, the next business day generally applies. Check with California for the exact observed calendar before filing.

Accepted format

Federal filing through the IRS Combined Federal/State Filing Program satisfies California's 1099-MISC requirement. No separate state submission is required, so there is no state-specific file format to conform to. The IRS transmits 1099-MISC records to California automatically after accepting the CF/SF submission.

Registration

Registration required: Yes

Direct filers must request a SWIFT account by emailing [email protected] with business name, address, FEIN, and primary/technical contact info. FTB responds within 24-48 hours. One SWIFT account may transmit on behalf of multiple entities.

Additional notes

California participates in the IRS Combined Federal/State Filing (CF/SF) Program. If you e-file 1099s with the IRS following IRS Publication 1220 and the amounts you report federally and to California are identical, you do not need to file separately with the Franchise Tax Board (FTB) - the IRS forwards the data via FIRE or IRIS. Direct filers (and any payer with a state-only difference) submit fixed-length .txt files via FTB's SWIFT system. The general 1099 due date with FTB is March 31 for electronic filings (February 28 on paper); FTB allows a 30-day extension via Form FTB 6274A.
