How do I amend my taxes to change filing status from separate to joint?
Changing from separate to a joint return. If you and your spouse are changing from separate returns to a joint return, follow these steps. Enter in column A the amounts from your return as originally filed or as previously adjusted (either by you or the IRS). Combine the amounts from your spouse’s return as originally filed or as previously adjusted with any other changes you or your spouse are making to determine the amounts to enter in column B. If your spouse did not file an original return, include your spouse’s income, deductions, credits, other taxes, etc., to determine the amounts to enter in column B. Read the instructions for column C on this page to figure the amounts to enter in that column. Both of you must sign Form 1040X.
