If you receive a corrected W-2 form (W-2C) after you already filed your tax return, first check what was corrected.
If the W-2C changes information that affects your tax calculations, such as your income, credits, or deductions, you should upload the W-2C in Sprintax and file an amended return.
If the correction is only for your name, address, taxpayer ID, or Social Security and Medicare wages and taxes (box 3, 4, 5 or 6), you do not need to upload the W-2C or amend your return.
Info: In general, you should file an amended return if the corrected form changes information that affects your tax calculations, including your residency or filing status, the number of dependents you can claim, or income, credits, or deductions reported on your original return.
