Does an IRS Installment Agreement Stop Penalties and Interest?

What does an installment agreement actually change?

Many taxpayers wonder whether setting up an IRS payment plan halts all extra charges. The answer is no. While an installment agreement can reduce one specific penalty, both penalties and interest generally continue in some form until the debt is paid off.

According to the IRS, the failure-to-pay penalty normally equals 0.5% of the unpaid taxes for each month or part of a month the balance remains outstanding. This penalty is capped at 25% of the unpaid taxes.

How much does the failure-to-pay penalty drop with a payment plan?

If you filed your tax return on time as an individual and receive approval for an installment agreement, the IRS reduces the failure-to-pay penalty rate to 0.25% per month or partial month while the plan remains in good standing.

This reduction applies to both tax shown on your original return and additional tax the IRS later determines you owe, as long as the return was timely filed. The lower rate helps slow the growth of the penalty but does not erase penalties already assessed.

Republic Tax Relief notes that readers facing existing tax debt often have questions about how payment plans interact with ongoing charges. The firm offers a free, no-obligation initial consultation to discuss suitability of private tax-resolution services for communicating with the IRS about your specific situation, including fees and scope of help.

Does interest stop accruing under an installment agreement?

Interest continues to accrue daily on any unpaid tax, penalties, and prior interest even after you enter an installment agreement. The IRS charges underpayment interest from the original due date of the tax until the balance reaches zero.

Interest rates can change quarterly, but once applied to a period they remain fixed for that time. Paying only part of what you owe each month means interest keeps adding up on the remaining balance. Full payment of the entire amount is required to stop further interest from accumulating.

When do penalties and interest finally stop?

Both penalties and interest stop growing only when you pay your tax balance in full. The IRS applies full monthly penalty charges even if you pay the account before the end of a given month.

If you fail to pay within 10 days after receiving a notice of intent to levy, the failure-to-pay penalty rate increases to 1% per month. Timely compliance with an installment agreement helps avoid this higher rate.

Can penalties or interest ever be reduced or removed?

The IRS may remove or reduce certain penalties if you can show reasonable cause and that you acted in good faith. However, interest generally cannot be removed unless the associated penalty is also abated.

Interest can only be reduced in cases of an unreasonable error or delay caused by an IRS employee. Taxpayers can request this using Form 843 or by writing to the IRS with supporting details.
