Back Taxes Don’t Wait. Neither Should You.
If you owe back taxes, you’re not alone and you’re not without options. This guide explains what back taxes are, why they grow so fast, what the IRS can do to collect, and the programs available to resolve your debt.
What Are Back Taxes?
Back taxes are taxes from a prior year that weren’t paid in full by the due date. Once that balance exists, it doesn’t sit still. The IRS charges two separate penalties and daily compounding interest, and they all start running immediately.
After five years, nearly half the total balance is penalties and interest, not tax. Filing your return on time, even if you can’t pay, is almost always the right first move. The failure to file penalty is ten times the failure to pay penalty. Filing stops the larger charge and can save thousands.
How a $25,000 Tax Balance Grows
This table shows how a $25,000 balance grows when the return was filed late and no payments were made. The failure to file penalty is reduced by the failure to pay amount when both apply in the same month (combined cap of 5%/month). Interest is calculated at 7% compounded daily.
| Time | Original Tax Debt | Penalties Added | Interest Added | Total Balance |
|---|---|---|---|---|
| Day 1 | $25,000 | $0 | $0 | $25,000 |
| 6 Months | $25,000 | $6,375 | $945 | $32,320 |
| 1 Year | $25,000 | $7,125 | $1,940 | $34,065 |
| 2 Years | $25,000 | $8,625 | $4,085 | $37,710 |
| 3 Years | $25,000 | $10,125 | $6,450 | $41,575 |
| 5 Years | $25,000 | $11,875 | $11,775 | $48,650 |
Estimates based on combined 5%/month penalty (4.5% FTF + 0.5% FTP) for months 1 through 5, then 0.5% FTP ongoing, plus 7% annual interest compounded daily. Actual figures vary based on filing dates and quarterly rate changes.
How Back Taxes Happen
Most back tax problems start with normal life events, not fraud. The IRS doesn’t care why it happened. They care that there’s a balance and that you resolve it.
IRS Resolution Options
The IRS offers several programs to resolve back taxes. The right one depends on what you owe, what you can afford, and whether the assessed amount is correct.
Installment Agreement
A monthly payment plan to pay your full balance over time. Guaranteed approval if you owe under $10,000 and can pay within 3 years. Streamlined setup online if you owe under $50,000 and can pay within 72 months. Larger balances require financial disclosure and negotiation.
Penalty rate drops from 0.5% to 0.25%/month once in place. Interest continues accruing until the balance is paid.
Partial Payment Installment Agreement
Monthly payments based on what you can actually afford, even if the balance won’t be paid in full before the 10 year collection statute expires. The remaining balance is written off when the statute expires.
The IRS reviews your finances every two years and can adjust payments upward if your situation improves. Not a settlement. You’re paying what you can for as long as the IRS can collect.
Offer in Compromise
Settle your tax debt for less than the full balance, if you qualify. The IRS calculates your “reasonable collection potential” based on assets plus projected future income. They’ll generally only accept what they believe they could collect from you anyway.
$205 application fee plus 20% down payment required. Must stay compliant for 5 years after acceptance or the deal is revoked.
Currently Not Collectible
If paying your tax debt would prevent you from meeting basic living expenses, the IRS can temporarily pause all collection activity. No levies, no garnishments. The 10 year collection statute continues running.
Your debt remains. Interest and penalties continue accruing. The IRS keeps your refunds. They review your situation periodically and can restart collection if your finances improve.
Penalty Abatement
First Time Abatement: Clean compliance history for the prior 3 years? The IRS will typically remove failure to file and failure to pay penalties, often with a single phone call.
Reasonable Cause: Serious illness, natural disaster, death in the family, or IRS error can justify penalty removal with documentation.
Amended Returns and Audit Reconsideration
If the IRS filed a Substitute for Return, assessed tax based on incorrect information, or disallowed deductions you’re entitled to, you can fight the liability itself.
Filing an amended return or requesting audit reconsideration can significantly reduce what you owe, and should be done before negotiating any payment arrangement.
How Taxpayers Actually Resolve IRS Debt
Payment plans are by far the most common resolution. Over 4 million Americans are currently on an installment agreement with the IRS. Meanwhile, Offer in Compromise acceptances have been declining sharply, even as more taxpayers apply.
| Fiscal Year | New Installment Agreements | OICs Submitted | OICs Accepted | OIC Acceptance Rate |

| FY 2016 | 2.6 million | 63,000 | 27,000 | ~43% |

The challenge with many payment plans is that the IRS calculates your monthly payment based on its own allowable expense standards, not your actual budget. If you earn $6,000 per month and the IRS calculates your allowable expenses at $4,800, they’ll expect $1,200 per month regardless of what your real expenses look like. Meanwhile, interest at 7% continues accruing on the unpaid balance. It’s common for taxpayers to make years of payments and still owe more than when they started.
What Can Make Back Taxes More Complex
Not all back tax situations are straightforward. These factors increase both the stakes and the difficulty of resolution.
If you haven’t filed, the IRS may file a Substitute for Return (SFR) on your behalf, without your deductions, credits, or exemptions. The result is often an inflated balance. You must be filing compliant before the IRS will consider any resolution program.
Unpaid payroll taxes are treated differently. The IRS can assess the Trust Fund Recovery Penalty (TFRP), making business owners personally liable for the employee withholding portion. Business cases get faster enforcement and more scrutiny.
Balances above $50,000 don’t qualify for streamlined payment plans. You’ll need to provide detailed financial information and negotiate terms. Above $250,000, expect a Revenue Officer assigned to your case.
If the amount the IRS says you owe is wrong, due to a substitute return, an audit error, or a missing credit, you may need to pursue audit reconsideration or an appeal before negotiating a resolution.
Coordinating a resolution strategy across multiple tax years and different tax types (income, payroll, penalties) requires careful planning. Each year has its own collection statute, and the IRS treats each module separately.
If the IRS has already filed a lien or issued a levy, you’re in active enforcement. Timing matters. You may need to request a collection hold while implementing a resolution, and that requires prompt action.
What Happens If You Don’t Resolve It
The IRS follows a predictable escalation pattern. After a series of notices over 4 to 6 months, they move to enforcement. That can include federal tax liens against your property, bank account levies, continuous wage garnishment, refund seizure, passport restrictions (if you owe over $62,000), and in serious cases, physical asset seizure.
For larger debts, the IRS assigns a Revenue Officer to personally work your case. Business owners with payroll tax issues face shorter timelines and more aggressive collection.

How We Approach Back Tax Problems
Every case is different, but the process follows the same disciplined framework. We don’t start by picking a program. We start by understanding the full picture.
Understand Your Options
We pull your IRS transcripts, review every notice, and map out exactly what you owe, which years are involved, and where you are in the collection process. If the IRS filed substitute returns or the assessed amount looks wrong, we identify that immediately. We determine whether the right move is to attack the liability itself, negotiate a payment arrangement, or both.
Get a Plan
Based on your financial situation, we build a strategy tailored to your case. That might mean filing amended returns to reduce an inflated balance, pursuing penalty abatement to lower the total, or identifying the right resolution program. If the liability is wrong, we address that first. There’s no point negotiating how to pay a balance that’s incorrect.
Negotiate an Agreement With the IRS
We handle all communication with the IRS directly. We prepare and submit the necessary forms, respond to IRS requests, and negotiate the terms of your resolution. If enforcement is active, we work to get collection holds in place while the resolution is being processed. The goal is the best possible outcome for your specific situation.
Manage Your Taxes Going Forward
Resolution isn’t the finish line. Most IRS programs require ongoing compliance: filing on time, paying estimated taxes, staying current. We help you set up systems to avoid falling back into the same situation. If the IRS reviews your case down the road (which they do for PPIAs and CNC status), we handle that too.
