# What happens if I owe back taxes?

Updated October 8, 20263 sourcesTaxTruce team[Fact checked](/editorial-standards)

The short answer

Back taxes keep growing with interest and penalties until you pay. The IRS follows a set path of notices, then can file a lien and levy your property. Interest is 7% a year for individuals in late 2026, compounded daily. The late payment penalty is 0.5% a month, up to 25%.

Each unpaid year has its own 10 year collection clock that starts when the tax is assessed.
