I sent an ammended return almost a month ago and still haven't received my refund. Does it usually take this long to get money back from an ammended return?

It can take up to 16 weeks for your Amended return to process and be approved. It is natural for it to take this long. You can track your amended taxes with the IRS tracking tool. It takes the IRS around 16 weeks to process your amended taxes. The processing time for amended state return differs from state to state. Contact your state to find out how long it takes them to process your amended taxes.
