Accumulating Interest and Additional Penalties
Interest compounds daily on both unpaid taxes and penalties. The failure-to-pay penalty continues to accrue at 0.5% per month (up to 25% total). What started as a manageable debt can quickly balloon. For example, $10,000 in unpaid taxes can grow to over $15,000 within 3 years when penalties and interest are included.
Consequences of Ignoring Tax Penalties
Ignoring IRS penalties or delaying response can lead to severe financial and legal consequences. Understanding what’s at stake helps motivate timely action and resolution.
