Your Balance Is Growing Right Now: The Exact Rates

If taxes are not paid by the due date, the IRS adds three types of charges: a failure-to-pay penalty, a failure-to-file penalty if the return was not filed, and interest that compounds daily. Filing an extension gives you more time to file but not more time to pay.

Failure to File vs. Failure to Pay

Many taxpayers delay filing because they cannot pay. That decision compounds the damage. The failure-to-file penalty is ten times more expensive than failure to pay alone. Both penalties continue accruing until you are in an approved resolution. The sooner you act, the less your balance grows.

Failure to File Penalty

The failure-to-file penalty applies when a return is not submitted by the deadline or extension date. The IRS charges 5% of the unpaid tax for each month or part of a month the return is late, capped at 25%. If a return is more than 60 days late, the minimum penalty is the lesser of $510 or 100% of the tax owed.

Failure to Pay Penalty

The failure-to-pay penalty applies when a return is filed but the balance is not paid in full. The rate is 0.5% per month, capped at 25%. The rate increases to 1% per month after a final notice of intent to levy. It drops to 0.25% per month once an IRS Installment Agreement is in place. Getting into a formal agreement cuts the penalty rate in half.

When Both Penalties Apply

When a return is filed late and the balance remains unpaid, both penalties apply simultaneously. The combined rate is capped at 5% per month during overlapping months.

How IRS Interest Builds Over Time

Interest is charged separately from penalties and continues until the balance is fully paid. The IRS updates interest rates quarterly. The rate is the federal short-term rate plus 3%. In recent years that has ranged from 7% to 8% annually, compounding daily. Interest begins the day after the tax payment was due. Extensions do not delay interest. A $10,000 balance at a 7% rate adds roughly $700 in interest over a year, before penalties.

These charges are compounding against your balance right now. Getting into a resolution stops that clock. Get a free consultation or call (800) 707-8065 — we tell you exactly where you stand and which path resolves it fastest.

The Cost of Waiting: Every Month Without a Resolution Costs More

Getting into a payment plan within the first two months reduces the failure-to-pay penalty rate from 0.5% to 0.25% per month, cutting it in half. It also lowers the interest base as payments come in. Every month without a resolution is a month the balance grows. Getting into a formal agreement stops that clock and puts collections on hold.

If your balance has already grown significantly, an Offer in Compromise or Penalty Abatement may reduce what you owe before you set up payments. Our team evaluates both paths at no cost.

Real Examples: What These Charges Look Like

Filed on time, paid 6 months late, $5,000 balance: Failure-to-pay penalty ~$150. Interest ~$175. Total added cost ~$325.

Filed 6 months late, unpaid, $10,000 balance: Failure-to-file penalty ~$2,250. Failure-to-pay penalty ~$300. Interest ~$350. Total added cost ~$2,900.

What the IRS Does Next: The Escalation Sequence

The IRS does not usually move straight to enforcement. It follows a defined notice sequence, but each step escalates. Ignoring notices does not pause them. By the time a final notice arrives, the window to stop a levy or garnishment without professional help narrows significantly. If you have received any notice below, contact us before the next one arrives.

• CP14 - Initial bill
• CP501 - Reminder notice
• CP503 - Urgent notice
• CP504 - Notice of intent to levy certain assets
• LT11 / Letter 1058 - Final Notice of Intent to Levy

Federal Tax Liens

A lien is a legal claim against property and a matter of public record. Lenders, title companies, and real estate attorneys find them in public record searches. They can block financing, prevent property sales, and affect your ability to close real estate deals. Liens often attach once balances grow beyond roughly $10,000, though thresholds vary.

Levies and Garnishments

A levy allows the IRS to seize assets. This includes bank account freezes and wage garnishments. Once issued, they move fast. A bank levy freezes funds for 21 days before the IRS takes them. A wage garnishment begins the very next pay period. If you have received a final notice or are already under a levy, contact us immediately. There is still a window to act, but it is narrow.

Passport Restrictions

Tax debt exceeding $66,000 (adjusted annually for inflation) can lead to passport denial or revocation under the IRS Seriously Delinquent Tax Debt program. Additional conditions must also be met.

Your Options Right Now — and How Omni Finds the Right One

Several paths exist for resolving IRS tax debt, and the right one depends on your specific balance, income, asset situation, and compliance history. Our team reviews all of these factors in a free consultation and tells you honestly which options you qualify for and which ones would be denied.

IRS Installment Agreements

IRS Installment Agreements allow monthly payments over time. While active, the failure-to-pay penalty drops to 0.25% per month instead of 0.5%, cutting the rate in half. Getting into a formal agreement also stops active collection action and gives you a structured path to resolution.

Currently Not Collectible

When income does not cover basic living expenses, the IRS may place an account in Currently Not Collectible status. This pauses active collection action while your financial hardship is documented. Penalties and interest continue to accrue, but enforcement stops. Our team prepares the financial documentation the IRS requires and submits it correctly the first time.

Offer in Compromise

Some taxpayers qualify to settle for less than the full balance through an Offer in Compromise. Approval depends on your income, allowable expenses, and asset equity. The IRS accepted roughly 21% of OIC applications in 2024. The application fee is $205 (waived for qualifying low-income taxpayers). Our team evaluates whether your numbers qualify before filing, and builds the strongest financial case possible if they do. If you have been told you do not qualify, a second opinion from our team costs nothing.

Penalty Abatement

Certain penalties may be removed through IRS Penalty Abatement, either first-time abatement for taxpayers with a clean prior compliance history, or reasonable cause relief. Note that interest can only be removed when it is tied to a penalty that is being abated.

Additional Issues for Business Owners

Business tax debt escalates faster than personal debt. Unpaid payroll taxes can trigger the Trust Fund Recovery Penalty, which allows the IRS to assess the debt personally against individuals deemed responsible, turning a business liability into a personal one. If your business has unpaid payroll taxes or multiple years of unfiled returns, the exposure compounds quickly. This is not a situation to navigate alone.

What to Do Right Now

These are the steps that reduce penalties and stop the balance from growing:

• Confirm which years are unfiled or unpaid
• File missing returns as soon as possible, which stops the failure-to-file penalty from continuing
• Make a good-faith payment if feasible, which reduces the interest base
• Get into an approved resolution: Installment Agreement, Currently Not Collectible, or Offer in Compromise

If you are unsure which step applies to your situation, that is exactly what our free consultation is for.

When to Stop Handling This Alone

At some point, the complexity of the situation outpaces what you can manage alone. That point is usually one of these:

• A levy or garnishment is imminent or already in progress
• Multiple years are unfiled
• A Revenue Officer has been assigned to your case
• You have received a CP504, LT11, or CP90 notice
• You are unsure which resolution option applies to your situation

The Bottom Line: What Happens If You Wait Longer

Unpaid taxes trigger penalties and interest, and that balance grows every month you are not in a resolution. The IRS follows a defined escalation process from notices to liens to levies. The further it goes, the harder and more expensive it is to resolve.

The options exist: Installment Agreements, Penalty Abatement, Offer in Compromise, Currently Not Collectible. Which one applies to you depends on your numbers. We have been figuring that out for clients for 20+ years.

The first step is a free consultation. There is no obligation and no pressure. We tell you where you stand and what your options are.

Frequently Asked Questions

How much does the IRS charge in penalties for not paying?

The failure-to-pay penalty is 0.5% of the unpaid balance per month, capped at 25%. If you also did not file on time, the failure-to-file penalty adds 5% per month, also capped at 25%. The combined rate can reach 5% per month. Getting into an Installment Agreement cuts the failure-to-pay rate to 0.25% per month.

How much interest does the IRS charge on unpaid taxes?

The IRS charges interest at the federal short-term rate plus 3%, updated quarterly. In recent years that rate has been 7% to 8% annually, compounding daily. Interest starts the day after the payment deadline and continues until the full balance is paid. Extensions to file do not delay interest.

Can IRS penalties be removed?

Yes, through first-time penalty abatement if you have a clean prior compliance history, or through reasonable cause relief if the failure to file or pay was due to circumstances beyond your control. Interest can only be removed when it is directly tied to a penalty being abated. Our team evaluates which type of abatement applies before filing anything.

What happens if I ignore IRS notices?

The IRS escalates through a defined notice sequence from initial bill to final notice of intent to levy. Ignoring notices does not pause them, it accelerates enforcement. Once a final notice is issued, the IRS can seize bank accounts, garnish wages, and file tax liens. Responding early is always better.

Does IRS tax debt affect my ability to sell property or get financing?

Yes. When an IRS tax lien is filed, it becomes a matter of public record. Lenders, title companies, and real estate attorneys find liens in public record searches. They can block financing, prevent property sales, and affect your ability to close real estate transactions. Since 2018, federal tax liens no longer appear on credit reports from the major bureaus, but they are fully visible in public records searches used in real estate and lending.

Should I try to resolve IRS debt on my own?

For a single year of unpaid taxes with a manageable balance, calling the IRS directly to set up a payment plan is reasonable. For larger balances, multiple years of debt, missing returns, business payroll tax issues, or any situation where enforcement has already started, professional representation matters.
