The National Taxpayer Advocate (NTA) has a caution for taxpayers who file a claim for refund after April 15 for tax years 2019 or 2020. They may have a timely filed claim, but the amount of the refund may be unexpectedly limited to $0 (effectively denied) in 2023 or 2024 because the IRS postponed the filing deadlines in 2020 and 2021 rather than extended them. The NTA recommends that for any future year for which there’s a filing deadline postponement, file for an extension, even if the return is ultimately filed by the postponed deadline. (However, it’s too late to apply this recommendation with respect to 2019 and 2020 returns.) For further explanation from the NTA:  Call or visit our website for more information!
