How many taxpayers owe the IRS each year?

Each year, millions of taxpayers owe money to the IRS due to underpayment of taxes, penalties, or other liabilities. While the exact number varies annually, reports indicate that in recent years, around 10-15% of taxpayers may carry a balance due at some point during the tax season. This translates to tens of millions of individuals and businesses owing the IRS at any given time. The IRS also frequently provides updates on tax delinquencies and compliance statistics.
