H&R Block Return Policy
MAXIMUM REFUND GUARANTEE
If you discover an error in the H&R Block tax preparation software that entitles you to a larger refund (or smaller liability), we will refund the software fees you paid to prepare that return and you may use our software to amend your return at no additional charge. To qualify for the H&R Block Maximum Refund Guarantee, the refund claim must be made during the calendar year in which the return was prepared and the larger refund or smaller tax liability must not be due to differences in data supplied or positions taken by you, your choice not to claim a deduction or credit, positions taken on your return that are contrary to law, or changes in federal or state tax laws after January 1, 2020, per H&R Block policy.
