Amended Tax Return processing times?

Question

I filed my taxes in March and got my refund about 10 days later. Then I realized I'd made a mistake (to do with rental mortgage interest and taxes, and active participation in rental) and so filed an amended tax return which will increase my federal and state refund. I mailed this on April 12th.

How long does it typically take to process an amended tax return and send a check?

Answer 1

8 to 12 weeks from the time the IRS receives the Amended Return

Answer 2

Amended returns typically run 8 - 12 weeks to process.
