Answer up to three questions and see the itemized estimate — surcharge, interest, and the usual compromise amount, each with the regulation it comes from.

Based on Sec. 248 and Sec. 249 of the Tax Code and the RMO 7-2015 compromise schedule, with the reduced EOPT (RA 11976) rates for micro taxpayers where they apply.

How this estimate works

We show every line of the computation and where it comes from. Fixers hide the math; we print it. The estimate assumes a calendar-year annual ITR and counts interest to today, Manila time.
