Department of Taxation and Finance

Approved software developers for corporation tax e-file

To participate in the New York State e-file program, you must use tax preparation software that has been tested by the Tax Department.  Our testing process ensures tax returns are properly formatted and can be processed when we receive them.  Tax Department testing does not imply that we endorse the quality of the software (see also Important Information Regarding Electronic Filing).

The software developers and products in the chart below are approved for corporation tax e-file.

The Main forms approved for tax year 2017 column lists all forms that the software developers tested and approved for tax year 2017 only.
