I received another 1098 mortgage interest tax form. Do I need to amend my taxes?

Yes, you should amend your return to include the additional 1098 that you received. You should not try to amend your return until the original return it has been fully processed and you have received your refund or your payment has cleared.

Amended returns do not “catch up” to your original return and replace them; they are processed as two separate returns.  
Amended returns have to be printed and filed by mail.  It can take the IRS up to 12 weeks or longer to process them.   If you are due a larger refund than on your original return, your amended return should only show the difference and you will receive a separate check for it.  If you owe money on your amended return, it will show only the new amount owed, you will have to mail a check with the return.

Do you need to send the previously unreported Form 1098 with the amended tax return to the IRS?
