under what circumstance will the irs charge you a late-payment penalty for taxes?
user
years ago i mailed my personal tax return one day after the due date, and my check was deposited as normal, and i never heard anything about it. as an employer, i once sent in my employee's withheld federal taxes one day after the due date, and i later received a letter stating my penalty for being late worked out to be around $600. the letter stated that since this was my first time being late they would waive the fee. in both cases, they could have charged me a late fee if they wanted to.
