If you miss a payment, the IRS imposes a penalty for not paying quarterly taxes on time. This estimated tax payment's late penalty is calculated based on the amount owed and the length of the delay.
For 2024, quarterly tax payments are due on April 15, June 17, September 16, and January 15, 2025. If you miss any of these deadlines, the penalty starts accruing from the day after the due date. The IRS charges interest on the unpaid amount, so the longer you wait, the more you’ll owe.
To avoid these penalties, it’s crucial to pay estimated taxes on time. If you realize you’re late, pay as soon as possible to minimize additional charges. You can easily pay estimated taxes online using the IRS Direct Pay system or the Electronic Federal Tax Payment System (EFTPS).
If you’re also late filing your return, you could face additional penalties. The IRS can charge a failure-to-file penalty, which is typically 5% of the unpaid taxes for each month your return is late, up to 25%.
