Embed the tax debt calculator
One line of code. When the IRS publishes a new quarterly rate or changes a penalty minimum, the embedded calculator follows.
Terms: keep the credit line under the calculator visible, do not alter the frame, and do not present it as tax advice or as a tool of the IRS or any government agency. The frame sets no cookie and sends us nothing about your readers. Questions: contact page.
Late filing and late payment penalties, daily interest, balance on the payoff day

This is not tax advice, and the IRS decides: your transcript, notices and the financial statement it reviews are what count. We receive nothing from any tax resolution firm, lender or preparer.
