If you have reported incorrect federal and/or state amounts in the original W-2s, you can file W-2c forms to correct them. Please note that you should only file a W-2 correction AFTER the SSA has accepted the original form. Since the original W-2 was filed through TaxFileApp, all the original federal and state information is available, you will need to provide the updated information.
Follow the instructions to correct the Federal and State amount:
- Sign in to your TaxFileApp account.
- In the Dashboard, Click Start New >> Form >> Form W-2c.
- Select the required tax year to correct the W-2 form.
- Click Continue under Correct W-2 Employee Details.
- Select the tax year and Business, then find the employees in the list. Click the Make Correction button to the right of the recipient.
- Under the Federal and State details, you can find the previously reported amount and a box to enter the correct information. Provide the correct information in the respective boxes and continue the flow. Review the flow and transmit the return.

Note: TaxFileApp currently does not support the direct state filing of W-2c. Please take care of fling W-2c with your state.
