By what date must a taxpayer claim a refund for an overpaid tax originally filed by April 15, 2021?

A taxpayer has a specific time frame in which to claim a refund for an overpayment of taxes. Generally, for an individual tax return that is timely filed, the rule is that a taxpayer must file a claim for a refund within three years from the original due date of the return.

In this case, if the original tax return was filed by April 15, 2021, the three-year period for claiming a refund would commence on that due date. Adding three years to April 15, 2021, brings the deadline to April 15, 2024. This means that to be eligible for a refund related to the tax return for that year, the taxpayer must claim it by this date.

Options that extend beyond this date are not valid, as they do not fall within the legal timeframe set for such claims. Therefore, the correct timeframe for claiming a refund on a tax return filed by April 15, 2021, is indeed until April 15, 2024.
