Connecticut State 1099 Tax Filing

Does Connecticut require state 1099 tax filing?

Yes, Connecticut requires forms 1099-NEC, 1099-MISC, & 1099-R to be filed with the Connecticut Department of Revenue Services.

Does Connecticut participate in Combined Federal/State Filing?

Yes, Connecticut participates in Combined Federal/State Filing. If you utilize CF/SF when filing your 1099s, the IRS will forward the information to the Connecticut Department of Revenue Services and you will not have to do so yourself.

However, if state withholding is reported on Forms 1099-NEC, 1099-MISC and/or 1099-R, you must file these forms along with the associated form CT-1096 directly with the Connecticut Department of Revenue Services through the My ConneCT, even if you used CF/SF.

Please note that BoomTax does not currently support filing for Form 1099-R.
