Don't let unsupported income, credits, and deductions delay your refund!

Before you file your return, make sure your records are in order and that you have acceptable proof of your eligibility for any income, credits, and deductions you're claiming; we may need you to provide us with additional information after you file to support your claim.

Review our checklists of acceptable proof to make sure you're only claiming what you're entitled to.
