New York E-Filing Overview

Eric Updated by Eric

NY state significantly changed the NYS-45 and NYS-1 forms and upload options in March 2025.
E-filing is required in most cases after April 30, 2015.

The New York tax department offers three methods for electronically filing withholding tax returns.

  • Method 1: Tax Department Web File. This method is the most popular among our users.
  • Method 2: Tax Department Web Upload. This method is very restrictive.
  • Method 3: FSET. CFS does not support FSET. FSET (Federal/State Employment Taxes) is a method available to third-party transmitters to file withholding returns, wage reports, and UI information. CFS is not a third-party transmitter or payroll processor. We cannot accept our customer’s returns and file for them.
All users must establish an Online Services Account as soon as possible.
NY state discontinued the copy and paste method in March 2025.
