So don’t send a check by the 18th? Won’t that mean I incur late fees/penalties? My assumption on handling it was to pay online on the 18th and mail the returns so they already had the money and I wouldn’t get late fees but the return wouldn’t be processed until they get to it.
If you pay the federal taxes owed on or before April 18 on the IRS website then your 2021 taxes were paid on time so there is no penalty.
If you mail the tax return on or before April 18, 2022 then the tax return was timely filed and there is no penalty. The postmark stamp on the envelope is used by the IRS for determining when the tax return was filed.
