When to File

Forms 1099-R, 1099-MISC, 1099-NEC, W-2G and Form CT-1096, Connecticut Annual Summary and Transmittal of Information Returns, are due January 31.

Form 1099-K is due no later than 30 days after such forms are filed with the IRS. Form CT-1096 will be completed as part of the electronic filing process when you upload the state copy of federal Forms 1099-R, 1099-MISC, 1099-K, 1099-NEC, and W-2G.

If the due date falls on a Saturday, Sunday, or legal holiday, the return will be considered timely if filed by the next business day.

Electronic Filing Requirements

If you file 25 or more Forms 1099-MISC, 1099-R, 1099-K, 1099-NEC, or W-2G you are required to file electronically unless you have been granted a waiver from this requirement. See Waiver From Filing Electronically.

If you file 24 or fewer Forms 1099-MISC, 1099-R, 1099-K, 1099-NEC, or W-2G you are encouraged to file electronically but may file paper forms without requesting a waiver. See Electronic Filing Through myconneCT.

DRS requires one filing for each CT Tax Registration Number. Therefore, if your company has multiple locations or payroll systems using the same CT Tax Registration Number, you must combine the files to complete your electronic filing within myconneCT.

DRS has no application or authorization procedure and does not assign submitter control codes for Forms 1099 or W-2G electronic filing.

Extension of Time to File

To request an extension of time to file you must complete Form CT-8809, Request for Extension of Time to File Information Returns and mail it on or before January 31. Form CT-8809 cannot be filed electronically.     

Waiver From Filing Electronically

DRS may waive the electronic reporting requirement only if the payer is unable to file electronically due to a documented hardship. To request a waiver complete Form CT-8508, Request for Waiver From Filing Information Returns Electronically and mail to DRS on or before January 1, Form CT-8508 cannot be filed electronically.

If a waiver is granted, your information returns must be submitted to DRS on CD. See Form CT-4804, Transmittal of Information Returns Reported on Compact Disk (CD).

Penalties

The penalty for late filing is $50.

A penalty of $5 per form (up to a total of $2,000 per calendar year) is imposed on payers who fail to file federal Forms 1099-MISC, 1099-R, 1099-K, 1099-NEC, or W-2G with DRS.

Failure to file the state copy of federal Form 1099-K with Connecticut will result in a civil penalty of $50 for the first month for each 1099-K that you are required and fail to file, plus $50 for each month, or fraction thereof, for which such failure continues. The total amount of penalty imposed will not exceed $250,000 per year.

The above penalties may also be imposed on payers who are required to file electronically if they file using any other media without first obtaining a waiver.

Record Keeping

Records pertaining to Connecticut information returns must be retained for at least four years after the due date of the return.

Amended Returns

An amended return is a return submitted by the transmitter to correct returns that were previously submitted and successfully processed by DRS but contained erroneous information.

For information returns filed through myconneCT, amended filings can only be done using the   Business Employer or Third-Party Bulk Filer login.

DO NOT SEND THE ENTIRE ORIGINAL FILE AGAIN. Send only the corrected Forms 1099 and W-2G that were erroneous.

All correction file entries must be transmitted in a new file. Make sure that the corrected file has the re-sub indicator (Field Position 6 of the Payee B record).

Forms 1099 and W-2G omitted from the original file must not be coded as corrections. Submit these returns under a separate Payee “B” Record as original returns. See Supplemental Returns.

After successful upload of the corrected information returns, you will be taken to Form CT-1096, Connecticut Annual Summary and Transmittal of Information Returns as it was originally submitted. Make necessary corrections to the Form CT-1096. Review, verify and submit, then receive a new confirmation number.

Supplemental Returns

Supplemental returns are processed the same as the original filing, but the transmitter must indicate that these information returns were not remitted in a prior file. After successful upload of any additional Forms 1099 or W-2G, you will be brought to Form CT-1096 where myconneCT has populated many of the fields based on the information you submitted. You will then verify the Form CT-1096 information, complete the quarterly breakout, and submit the return; then receive a new confirmation number.

  • Supplemental returns are information returns omitted from the original file, and must not be coded as corrections.
  • Supplemental filings through myconneCT can only be done using the Business Employer Login or Bulk Filer login.
  • After indicating that these are supplemental returns not previously submitted, you will be able to repeat the file process.

Use of Agent

Payers using a service to electronically file or transmit information are responsible for the accuracy and timeliness of their information returns. If a transmitter fails to meet the electronic filing requirements, the payer is liable for any penalties imposed by DRS.

Combined Federal/State Filing Program

Connecticut participates in the Combined Federal/State Filing Program (CF/SF). However, you must also file Forms 1099-MISC, 1099-NEC, and 1099-R that have Connecticut withholding, and all Forms 1099-K, directly with DRS through myconneCT even if you participate in the CF/SF. See Section II. Electronic Filing Through myconneCT.

The only forms filed through CF/SF that will satisfy the DRS filing requirement are Forms 1099-MISC, 1099-NEC, and 1099-R with no Connecticut withholding. The due date is January 31.

Records T, C, and F are identical to the filing requirements in this publication. Differences in the record requirements are as follows:

Record A

  • Field position 6 (Combined Federal/State Filer) must contain a 1.

Record B

  • Field positions 747-748 (Combined Federal/State Code) the code for Connecticut is 08.

File Corrections

Any corrections to 1099-MISC, 1099-NEC, 1099-K, or 1099-R files using the Federal/State Combined Filing Program should be replaced by uploading the correct forms.

Data Record Descriptions Record Types

Use the information below as well as the list of technical requirements and specifications in the other sections of this publication to prepare Forms 1099-R, 1099-MISC, 1099-K and W-2G filings. See Examples of Proper Record Sequence for Filing Forms 1099-R, 1099-MISC, 1099-K, 1099-NEC, and W-2G Information Returns.

These record formats are identical to those published by the IRS in Publication 1220, Specifications for Electronic Filing of Forms 1097, 1098, 1099, 3921, 3922, 5498, and W-2G.

The Form 1099-R, 1099-MISC, 1099-K, 1099-NEC, and W-2G Record Specifications includes formats for the following record types required by DRS. See the Form 1099-R, 1099-MISC, 1099-K, 1099-NEC, and W-2G Record Specifications, for proper record sequence.

  • T Record – Transmitter Record
  • A Record – Payer Record
  • B Record – Payee Record
  • C Record – End of Payer Record
  • F Record – End of Transmission Record

Transmitter T Record identifies the entity transmitting the file. It must be the first record of each file.

Payer A Record identifies the institution or person making the payments. The number of Payer A Records depends on the number of payers.

Payee B Record contains the payment information from the information returns. The record layout for field positions 1 through 543 is the same for all types of returns.

Field positions 544 through 750 vary for each type of return to accommodate special fields for individual forms.

End of Payer C Record has the total number of payees (B Records) and the totals of the payment amount fields filed by a payer or return type.

End of Transmission F Record is the summary of payers (A Records) in the entire file. It must be the last record in the file.

There is no K Record (State Totals) requirement for Connecticut. If included, it will be ignored.

Punctuation may be used when appropriate. Do not include titles in the payer name field. Titles make it difficult for DRS to determine an individual payer’s name and may prevent DRS from properly crediting return data.

If it is impossible to remove a title, then you must report the surname first.

Money Amounts

All money amounts are strictly numeric. They must include both dollars and cents with the decimal point assumed. Do not round to the nearest dollar.

Example: $5,500.99 = 000000550099

Do not use punctuations in any money field. Negative money amounts are not allowed.

Right justify and zero fill all money fields. Enter zeros in a money field that is not applicable.

Programmer’s Review
General Information
  • You must follow the Connecticut specifications for record layouts.
  • If a return contains errors, DRS will provide a list of the failed records with explanations. Simply correct the file and resubmit the entire file.

    Technical Requirements

  • Data must be saved using the ASCII character set.
  • Each record in the file must be 750 characters in length followed by a carriage return/line feed (CR/LF).
  • Data must be entered in each record in the exact

    positions shown in the Form 1099-R, 1099-MISC, 1099-K, 1099-NEC, and W-2G Record Specifications

  • Do not place a record delimiter before the first record of the file.
  • Do not place more than one record delimiter, for example, more than one carriage-return or line feed combination, following a record.
  • Do not place record delimiters after a field within a record.
  • DRS recommends that the File Name be CTTAX followed by the 4-digit calendar year of the data you are uploading (for example, CTTAX2099).
  • File name should end with a file extension name of .txt or .dat.file. It must be the first record of each file.

  • The payment year must be in a YYYY format.
Proper Order of Records for Files With More Than One Payer

If a file contains information returns for more than one payer, do not use Transmitter T Record(s) or End of Transmission F Record(s) between payers. Each file can only have one ‘T’ record and one ‘F’ record.

See Examples of Proper Record Sequence for Filing Forms 1099 R, 1099 MISC, 1099 K, 1099 NEC, and W-2G Information Returns.

Money Amounts
