my guess is the 25% id 25% of the total due.
taxpayer. the $1600 was due 7/15/2020. if you filed an extension you are incurring penalties of .5 % month + interest from 7/15/2020 until paid off if you did not file an extension the penalties are 5% a month from 7/15/2020 for up to 5 months (after 5 months the penalty falls to .5%) + interest until paid off
