Without a postmark or a copy of a receipt from certified mail, you cannot prove when you mailed your tax return. When you mailed the return did you pay your tax due? How did you pay? Did you enclose a check or money order? Pay on the IRS site? Is the IRS billing you for late filing penalties and/or interest on the amount of tax you had to pay?
