1. Click the ‘Get Form’ button to access the W3 form and open it in an online editor.
2. Enter the total Maine income tax withheld as reported on payee statements in line 1. The amount should match what is documented in box 17 of federal Form W-2.
3. Fill in the total Maine income tax reported on quarterly reports for the year in line 2. Make sure to include only the corrected amounts if you amended any quarterly returns.
4. If you are a third-party payer of sick pay, enter any applicable withheld amounts in line 3. This should reflect the amount reported in your quarterly returns that is included in Annual Wage Statements (Forms W-2).
5. Complete line 4 if you are an employer who issues Forms W-2 that report withholding remitted by a third-party payer of sick pay. Enter the withheld amount, and provide the third-party payer's name and ID number in the corresponding fields.
