Tools
Check which information returns must be filed with Connecticut, what triggers state filing, key deadlines in 2027, IRS eFiling rules, and when Combined Federal/State Filing satisfies state requirements.
Miscellaneous Information
File when reportable payments are made to Connecticut residents, even if there wasn’t any state income tax withholding. For nonresidents, file if you paid for services that were performed wholly or partly in Connecticut. Under the federal rules for 2026 TY, the general 1099-MISC reporting threshold is $2,000 for some payment types. But royalties stay at $10, while gross proceeds paid to attorneys and cash payments for fish purchased for resale remain $600.
Nonemployee Compensation
If you paid reportable nonemployee compensation to Connecticut residents, and to nonresidents whose services were performed wholly or partly within the state. No Connecticut withholding is needed to trigger it. Federally, 2026 payments have a $2,000 threshold, but backup withholding rules may apply for any small amount.
Broker and Barter Exchange Transactions
Connecticut does not generally require routine state filing of all Forms 1099-B. Form 1099-B becomes subject to Connecticut reporting only in limited situations, such as when Connecticut withholding or other Connecticut-specific reporting requirements apply.
Distributions From Pensions and Retirement Plans
Distributions paid to Connecticut residents need this filing. No withholding is required for residents. Nonresidents only trigger the requirement if state income tax was withheld. Federally, Form 1099-R generally covers designated distributions of $10 or more.
Wage and Tax Statement
State copy of Form W-2 is needed when employees were paid Connecticut wages, regardless of whether Connecticut tax was withheld. Form CT-W3 must be filed with the submission.
Payment Card and Third-Party Network Transactions
Connecticut requires direct filing of 1099-K with DRS when reportable payment card or third-party network transactions are associated with a Connecticut payee; CFSF does not satisfy the state requirement. While federal payment card transactions are reportable at any amount, the TPSO threshold is over $20,000 and 200+ transactions.
Certain Gambling Winnings
File Connecticut Lottery winnings paid to residents and nonresidents, regardless of Connecticut income tax withholding. The same goes for reportable gambling winnings paid to Connecticut residents, regardless of withholding. For 2026 payments, the federal reporting threshold is generally $2,000, subject to the rules for each gambling type and, where applicable, the 300-times-the-wager test.
Keep the federal threshold separate from Connecticut’s statutory $600 information-return rule until DRS publishes updated guidance for tax year 2026.
The recipient statements for most 1099 forms for 2026 TY should be sent out by February 1, 2027. Forms 1099-B and 1099-MISC which have amounts in boxes 8 or 10 are due by February 16, 2027, since February 15 is a federal holiday.
If you file 25 or more 1099 or W-2G forms or 25 or more W-2s in Connecticut, then you must use eFiling. Paper filing is allowed below if you have 24 forms or less, even without a waiver. But keep in mind that the federal threshold for eFiling is 10 or more information returns in total.
If you require more time, then you should send Form CT-8809 by the applicable deadline. Connecticut does not accept Form CT-8809 electronically.
Collect taxpayer information, validate, and eFile applicable federal and Connecticut information returns through one secure workflow.
Connecticut takes part in the IRS CFSF Program. But CFSF only covers Forms 1099-MISC, 1099-NEC, and 1099-R, and only if there's no Connecticut withholding. If you want to meet Connecticut’s earlier deadline through CFSF, send the eligible form by February 1, 2027.
When Connecticut tax has been withheld from a 1099-MISC, 1099-NEC, or 1099-R, you should file directly with DRS via myconneCT. The same goes for every Connecticut-required Form 1099-K and W-2G. But note that W-2 has a separate W-2/CT-W3 filing process.
To file directly, you must submit Form CT-1096 together with your 1099 and W-2G forms. Tax1099 charges $0.99 per form for direct state filing and $4.99 for Form CT-1096.
Also, the IRS is transitioning from the legacy FIRE system to the more modern IRIS for filing information returns. For federal tax year 2026 returns (filed in 2027), IRIS will be the only way to eFile. However, direct filings to Connecticut will continue to work via myconneCT.
Connecticut usually follows updates to the Internal Revenue Code, but the state can decide not to follow every federal change. When it comes to information returns though, Connecticut has its own statutes and DRS instructions, so changes at the federal level don’t automatically affect state thresholds.
OBBBA increased the federal reporting threshold for certain 2026 payments from $600 to $2,000, including nonemployee service payments on Form 1099-NEC and some Form 1099-MISC categories. However, Connecticut hasn't adopted this $2,000 threshold. The state continues to apply the $600 threshold to applicable information returns, and $10 for interest or dividends.
For Form 1099-K, OBBBA restored the TPSO threshold to gross payments over $20,000 and more than 200 transactions, though payment card transactions remain reportable at any amount. Connecticut's payee-location rule and its direct-filing requirement for every 1099-K still apply on top of that.
Form W-2G 2026 payments generally have a $2,000 federal threshold. Gambling-type rules and the 300-times-the-wager test still apply where required. Connecticut keeps its resident, lottery-winnings, and direct-filing rules unchanged.
Forms 1099-NEC and 1099-MISC for TY 2026 also have new federal fields for cash tips, Treasury tipped-occupation codes, and qualified overtime compensation. These don't change Connecticut's own conditions, such as the resident and source rules for 1099-MISC and 1099-NEC, the residency and withholding rules for 1099-R, and CFSF's limited coverage across the board.
As of now, Connecticut DRS includes Forms 1099-MISC, 1099-NEC, 1099-R, 1099-K, and W-2G in its direct filing program. If you’re handling Form W-2, that’s a separate W-2/CT-W3 process. As for Forms 1099-B, 1099-INT, and 1099-G, those aren’t listed as direct filing requirements on the latest DRS page.
Even if you didn't withhold any Connecticut income tax, file the state copy of Form 1099-NEC or 1099-MISC when you make reportable payments to residents. For nonresidents, file if the payment was for services performed wholly or partly in Connecticut, and there wasn't any withholding.
Form 1099-R is for any distribution paid to a Connecticut resident, regardless of whether state income tax was withheld. For all other recipients, though, withholding is what triggers filing.
File Form 1099-K for payees located in Connecticut or with locations in Connecticut. Every 1099-K required by the state must be filed directly with DRS because CFSF doesn't handle it. And don’t forget, the state return is due within 30 days after filing with the IRS.
Only in some situations. Forms 1099-MISC, 1099-NEC, and 1099-R are covered under CFSF. But only when no Connecticut tax was withheld. If you withheld tax on any of those, file directly. Always file every 1099-K and W-2G directly with DRS.
These are the forms that are due by February 1, 2027 (January 31 falls on Sunday): 1099-R, 1099-MISC, 1099-NEC, W-2G, CT-1096, W-2, and CT-W3. Form 1099-K must be filed within 30 days after IRS filing. And the electronic filing threshold is 25 or more returns.
Get extensions by mailing Form CT-8809 by the deadline, as there's no electronic option for this one. If you want relief from mandatory eFiling, you can mail Form CT-8508. Send it at least 30 days before the due date and include proof of hardship. Any corrections or supplemental filings can be sent via myconneCT under the Business Employer or Third-Party Bulk Filer login. And don’t send the entire original file, only the corrected records.
OBBBA has increased the federal reporting threshold for Form 1099-NEC nonemployee compensation, certain 1099-MISC payments, the TPSO threshold for Form 1099-K, and Form W-2G for TY 2026 payments. But Connecticut continues to apply the earlier $600 threshold for general information returns and $10 for interest or dividends. Connecticut's own rules on recipients, source, withholding, CFSF, and direct filing still apply as they are.
With Tax1099, you get one secure workflow to prepare, validate, and eFile confidently.
