You are required to e-file your New York State general business and corporation returns and extensions if you meet all of the following conditions:

• You do not use a tax return preparer to prepare corporation tax returns and/or extensions; and

• You have broadband internet access.

Visit the Tax Department website at www.tax.ny.gov for more information on New York State's e-file mandates.

Electronic Filing is available for the CT-33, CT-33-NL, CT-400, CT5, and CT5.1. Please note that when e-filing the CT-33 / CT-33-NL, all applicable supporting forms (i.e., CT-33-M, CT-33-R, and CT-33.1) will automatically be included with the e-filing. All returns are routed through the IRS Modernized E-filing system. Independent software companies develop proprietary products which calculate and prepare the return, then transmit it to the IRS; from there it is passed on to the state .

To complete the electronic filing process for New York, please follow the steps outlined in the Efiling help topic. Fill out the return completely, with all company, premium, and other required information, just as you would a paper return.

Once you have chosen to submit the return, you may need to allow a few moments for the encrypted data file to transfer. You should see a message stating that the file transfer has been completed. You will then be provided with a submission ID. Soon afterwards, you should receive an email confirming the transmission of the file to the IRS at the email address you provided on the form. This email will contain your submission ID as well. Please retain this for your records.

New York will generate an acknowledgement for all returns received. The acknowledgements are available within 3 business days after a successful transmission to the IRS. If the form is accepted, you will receive an acceptance acknowledgement and the filing will be reviewed and processed. If a timely filed New York State submission is rejected by NYS due to an error, there is a 7-day transmission perfection period to allow the filer to correct and resubmit the document. The document MUST be resubmitted within 7 calendar days from the date the document was rejected. Also, the corrected re-submission MUST contain the original submission ID of the rejected return/extension in the appropriately designated field on the return.

Payment for the CT-33, CT-33-NL, and the Extensions may be paid in any of the following ways: via direct debit from a bank account, using the CT-200-V voucher & check, or via ACH credit initiated by taxpayer.  

Payment for the CT-400 (Estimated returns) can be via direct debit from a bank account or ACH credit initiated by taxpayer.

New York does not support International ACH Transactions (IAT).
