Connecticut requires state copies of certain 1099 forms and W-2G forms when Connecticut reporting rules apply. 1099Online helps you prepare federal and Connecticut state filings, including Form CT-1096 details, in one secure workflow.
Connecticut is a rolling conformity state, meaning it generally follows federal Internal Revenue Code changes, unless Connecticut law provides a modification or decoupling rule.
The One Big Beautiful Bill Act (OBBBA), signed on July 4, 2025, updated Forms 1099-MISC, 1099-NEC, and 1099-K with new reporting fields for cash tips and overtime compensation.
The Connecticut Department of Revenue Services has not issued any separate bulletin to decouple from OBBBA. Connecticut's residency sourcing rules, withholding requirements, and CT-1096 reconciliation requirements carry forward unchanged for TY 2026.
Connecticut requires payers to submit state copies of certain federal information returns to the Department of Revenue Services (DRS) when Connecticut reporting rules apply. Based on current DRS guidance, these are the forms Connecticut requires for state 1099 filing.

Connecticut gives payers 2 options for submitting state 1099 copies to DRS: direct filing through the myconneCT portal, or the IRS Combined Federal/State Filing (CF/SF) program. CF/SF does not satisfy all Connecticut filing obligations. The right method depends on the form type and whether Connecticut income tax was withheld.
| Form | CF/SF Participation | Direct State Filing | Electronic Threshold |
|---|---|---|---|
| 1099-NEC, 1099-MISC, 1099-R | Yes, only when no CT withholding | Required when CT income tax was withheld | 25 or more forms |
| 1099-K | No | Required only when Connecticut reporting requirements apply | 25 or more forms |
| W-2G | No | Required only when Connecticut reporting requirements apply | 25 or more forms |
Payers filing 25 or more Connecticut information returns must file electronically through myconneCT unless a hardship waiver applies.
The deadlines for Connecticut state 1099 filings depend on the form type. When a due date falls on a Saturday, Sunday, or legal holiday, the due date moves to the next business day.
