Short answer: File every missing return first, even the ones you can’t pay. The IRS won’t negotiate any payment arrangement until you’re compliant, and the penalty for not filing is ten times the penalty for not paying. Once the returns are in and the balances are assessed, you combine every year into a single payment plan and choose from six collection options.
Why filing comes before paying
This is the part most people get backwards. The two penalties are not the same size, and they are not close.
| Penalty | Rate | Cap |
|---|---|---|
| Failure to file | 5% of unpaid tax per month or part month | 25% |
| Failure to pay | 0.5% of unpaid tax per month or part month | 25% |
Filing late costs ten times what paying late costs. If a return is more than 60 days late, a minimum penalty also applies — the lesser of an inflation-indexed dollar amount or 100% of the tax due. Interest runs on top of both, compounded daily. (IRS: Penalties)
The IRS underpayment interest rate held at 7% for the fourth quarter of 2026. That’s the rate accruing on your balance while you decide what to do. See our breakdown of what Q4 2026 interest actually costs.
What “compliant” means to the IRS
You cannot set up a payment plan, request Currently Not Collectible status, or submit an Offer in Compromise while returns are missing. The IRS calls this filing compliance, and its long-standing internal policy is that filing the last six years of returns generally satisfies it. (IRS Policy Statement 5-133)
So the sequence is fixed:
- File every unfiled return — even if you owe and can’t pay a dollar of it.
- Let the IRS assess the balances so you know the real number.
- Fix the withholding or estimated-payment problem that created the balance.
- Choose a collection option for the combined balance across all years.
Step 3 is the one people skip
A payment plan that you default on is worse than no plan. The most common way to default is not missing a payment — it’s owing again the following year. The IRS terminates installment agreements when you fall out of compliance on a new balance.
If you’re a W-2 employee, that means raising your withholding on Form W-4. If you’re self-employed or run a business, it means calculating and actually making quarterly estimated payments. You cannot estimate those correctly without current books. That is the bookkeeping problem hiding inside the tax problem.
The six options for the balance
Once returns are filed and balances assessed, these are the paths. You may qualify for more than one. You may qualify for none.
| Option | What it does | Typical threshold |
|---|---|---|
| Penalty abatement | Removes penalties (not tax or interest on tax) for reasonable cause, or First-Time Abate if you have a clean three-year history | No balance limit |
| Short-term payment plan | Up to 180 days to pay in full | Under $100,000 in combined tax, penalties and interest |
| Long-term installment agreement | Monthly payments, generally up to 72 months | Under $50,000 in combined tax, penalties and interest |
| Partial Pay Installment Agreement | Monthly payments that won’t retire the full balance before the collection period expires | Requires Form 433 financial disclosure |
| Currently Not Collectible | Collection paused; no levies or garnishment while it lasts | Requires Form 433 financial disclosure |
| Offer in Compromise | Settles the debt for less than the full amount | Requires Form 433-A (OIC) or 433-B (OIC) |
All years combine into one arrangement. You do not negotiate 2023, 2024 and 2025 separately. (IRS: Online Payment Agreement)
What Form 433 actually does
Form 433 is the Collection Information Statement — a financial statement in three main flavors: 433-A for individuals, 433-B for businesses, and the shorter 433-F used in many phone cases. Its single purpose is to calculate your monthly disposable income using allowable expenses.
Allowable is a term of art. The IRS publishes Collection Financial Standards — national and local caps for food, clothing, housing, utilities, transportation and out-of-pocket health care. Your kid’s travel sports, private tuition, and streaming subscriptions are not allowable expenses. You can keep paying them. The IRS simply won’t subtract them when it calculates what you can afford.
This is why accurate records matter more than persuasion. The number that comes out of Form 433 is arithmetic, not argument.
When the IRS will settle for less
An Offer in Compromise is not a negotiation about fairness. The IRS accepts less than the full tax only when it concludes it cannot collect the full amount within the remaining collection period, based on your income, your assets and your allowable expenses.
Most offers are rejected. Across recent years the IRS has accepted roughly one-third of the offers submitted, per the annual IRS Data Book. The application fee is $205 unless you qualify for the low-income waiver, and the IRS keeps any payments submitted with a rejected offer.
Acceptance is not the end of it, either. Form 656 requires you to file and pay on time for five years after the offer is accepted — miss one deadline and the IRS can default the agreement and reinstate the balance. See what happens when an accepted Offer in Compromise defaults.
Before you pay anyone to file one, run the IRS’s own free Offer in Compromise Pre-Qualifier. It uses the same arithmetic the IRS will.
What Currently Not Collectible does and doesn’t do
If the Form 433 math shows you can’t pay anything, you can request Currently Not Collectible status. Expect a financial interview by phone that follows the form line by line — typically 30 to 45 minutes. Have the completed form in front of you.
What CNC does: stops bank levies and wage garnishment.
What CNC does not do: erase the debt. You still owe it. Interest and penalties keep running. Any future refund is seized and applied to the balance. The IRS reviews your situation periodically and resumes collection when your income recovers.
Liens
A federal tax lien protects the government’s claim against your property. It is not a punishment and it is not permanent. A lien can be withdrawn before the debt is paid in full, but you have to meet specific criteria and be actively paying — most commonly by entering a direct debit installment agreement and requesting withdrawal on Form 12277. (IRS: Understanding a Federal Tax Lien)
About the firms advertising on TV and radio
Every option above is one you can pursue yourself, free, directly with the IRS. Nothing on this list requires a paid intermediary.
The Federal Trade Commission has brought enforcement actions against tax relief operations for charging large upfront fees and failing to deliver the settlements they advertised, and maintains standing consumer guidance on tax relief companies. The pattern it describes is consistent: promise a settlement before reviewing your finances, collect a large fee upfront, then bill monthly.
Treat any unsolicited pitch with suspicion — including forum posts and comments that read like a fellow taxpayer sharing a success story. Astroturfing is cheap.
If you do want representation, use someone credentialed who can represent you before the IRS — a CPA, an Enrolled Agent, or a tax attorney:
- IRS Directory of Federal Tax Return Preparers with Credentials
- National Association of Enrolled Agents directory
- Low Income Taxpayer Clinics — free or low-cost representation if you qualify
- Your state board of accountancy or state bar association
Call several. Ask what the fee covers and what it doesn’t. A penalty abatement plus an installment agreement is routine work. An Offer in Compromise is not, and is priced accordingly — often several thousand dollars, frequently billed upfront.
Where bookkeeping fits — and where it doesn’t
CentsIQ does not file tax returns, and we are not a tax relief firm. We don’t represent anyone before the IRS, we don’t submit Offers in Compromise, and we won’t promise you a settlement.
What we do is the part that has to be right before any of the above works. Every option on this page runs on numbers from your books:
- Unfiled returns need clean books first. Your CPA or EA cannot file 2023, 2024 and 2025 without categorized transactions and reconciled accounts for each year. Catch-up bookkeeping is usually the actual bottleneck.
- Form 433 needs real numbers. Business income, business expenses, owner draws. Guessing on a Collection Information Statement is how people end up with a payment they can’t sustain.
- Estimated payments need current financials. This is step 3 — the one that stops you from owing again next year and blowing up the plan you just set up.
- Staying compliant needs monthly books. An installment agreement terminates when you fall behind again.
If your returns are unfiled because the books aren’t done, that’s the problem we solve. We do catch-up bookkeeping, monthly bookkeeping and year-end preparation for your tax professional — we get the records into shape and hand them to the CPA or EA who files.
CentsIQ is based in Seattle and works with clients nationwide, remotely.

Frequently asked questions
Should I file a tax return if I can’t pay what I owe?
Yes. File it. The failure-to-file penalty is 5% of the unpaid tax per month, capped at 25%. The failure-to-pay penalty is 0.5% per month, also capped at 25%. Not filing costs ten times as much as not paying, and the IRS won’t discuss any payment arrangement until your returns are in.
How many years of back tax returns do I have to file?
Generally the last six years. IRS Policy Statement 5-133 treats six years of filed returns as sufficient for compliance in most collection cases, though a revenue officer can require more. You must be compliant before the IRS will approve a payment plan, Currently Not Collectible status, or an Offer in Compromise.
Can I combine multiple tax years into one IRS payment plan?
Yes. Once all returns are filed and balances assessed, every year is combined into a single installment agreement. You don’t negotiate each year separately. Apply through the IRS Online Payment Agreement tool or by phone.
What is Form 433 used for?
Form 433 is the Collection Information Statement. The IRS uses it to calculate your monthly disposable income from your income, assets and allowable expenses — expenses capped by published Collection Financial Standards. Discretionary spending like children’s activities or private tuition is not allowable and won’t reduce the amount the IRS expects.
Will the IRS settle my tax debt for less than I owe?
Only if it concludes it cannot collect the full amount within the remaining collection period, based on your income, assets and allowable expenses. Roughly one-third of Offers in Compromise submitted are accepted. Run the free IRS Offer in Compromise Pre-Qualifier before paying anyone to prepare one.
Does Currently Not Collectible status erase my tax debt?
No. CNC pauses collection — no bank levies, no wage garnishment — but you still owe the money. Interest and penalties continue to accrue, future refunds are applied to the balance, and the IRS resumes collection if your financial situation improves.
Can a federal tax lien be removed before I pay the debt in full?
Yes, in specific circumstances. The most common route is entering a direct debit installment agreement, making payments, and requesting withdrawal of the Notice of Federal Tax Lien on Form 12277. You must meet the IRS criteria; withdrawal is not automatic.
Do I need a tax relief company to set up an IRS payment plan?
No. Every option — penalty abatement, installment agreements, Currently Not Collectible, Offer in Compromise — can be requested directly with the IRS at no cost beyond IRS fees. If you want representation, use a credentialed professional: a CPA, an Enrolled Agent, or a tax attorney. The FTC publishes consumer guidance on tax relief companies.
