If you paper file, it will take three to four weeks for the IRS to process the return and acknowledge your refund. If you e-file, you will get a notice of arrival within 24 hours and confirmation of refund within 72 hours.

For those who file an amended return, however, the period to receive a refund check will take 8-12 weeks.
