What happens if you don't pay the IRS? The balance can grow through penalties and interest, and the agency can eventually seize income or property. People who cannot pay in full may qualify for collection relief or a payment plan.
What happens if you don't pay the IRS
Ignoring a tax bill does not make the obligation disappear. The IRS can use income information reported on W 2 and 1099 forms to estimate what a person earned, even when that person has not filed a return. The agency may then prepare a Substitute for Return, or SFR, using the information available to it.
An SFR can leave out deductions for business expenses, tax credits and dependents. It may also use a filing status that does not reflect the taxpayer's circumstances. For example, the IRS may treat a married person as filing separately, or an unmarried person as single rather than potentially eligible to file as head of household. Those omissions can make the calculated bill higher than it would have been with a complete return.
Not filing can also add a failure to file penalty on top of a failure to pay penalty. Once the IRS assesses a balance, an additional penalty of 0.5% of the unpaid amount is charged each month. Interest accrues on the tax and penalties, and compounds daily. The bill can therefore increase even if the taxpayer makes no new purchases or incurs no new tax debt.
Filing an accurate return is an important first step for someone who has not filed. It gives the IRS a fuller picture than an SFR and can include relevant deductions, credits, dependents and filing status. A return does not erase a balance, but it can establish the amount actually owed and help clarify which payment options fit.
How collection notices can lead to a levy
A tax lien and a levy are different stages of collection. A lien is the legal claim attached to property because of unpaid tax. A levy is the step in which the IRS takes property or funds to satisfy the debt. If the debt remains unresolved and the required collection steps proceed, the agency can pursue wages and other income, Social Security and retirement benefits, bank accounts, and tangible property such as a car or home.
There are limits and procedures, but the consequences can reach beyond a checking account. The IRS cannot pursue someone's residence through a levy when the levy amount does not exceed $5,000. That protection does not mean every other asset is protected, or that a taxpayer should wait to act until a levy is threatened.
When the IRS prepares an SFR, it sends a notice of deficiency. The taxpayer then has 90 days to file a return or challenge the matter in tax court. If no action is taken, collection can move forward based on the SFR. A taxpayer who receives this notice should read the deadline carefully and address the underlying return and balance promptly.
For a person who files a return but does not pay the full amount, the IRS should send a notice stating the amount due within 60 days of the filing. The assessment date, rather than simply the arrival of a notice, starts the collection time limit. Keep notices and return records together so the assessed amount and dates are clear.
IRS payment options and who may qualify
People who cannot pay without undue hardship have several ways to ask the IRS for relief. The options differ: some pause collection temporarily, one seeks an agreement to settle for less, and installment agreements spread payments over time. A request is not the same as approval, and the IRS reviews financial circumstances for relief that reduces or delays collection.
| Option | What it does | Eligibility or terms | Trade off |
|---|---|---|---|
| Currently not collectible status | Pauses collection while financial hardship continues. | For a taxpayer facing temporary financial hardship. | Collection is delayed, not described as cancelled, and can resume when circumstances change. |
| Offer in compromise | Allows a taxpayer to seek a settlement for less than the full tax debt. | The taxpayer must show it is unlikely the full amount can ever be paid. | The IRS closely reviews the person's financial situation. A rejected offer can be appealed to IRS Appeals. |
| Short term installment agreement | Lets the taxpayer pay the balance in monthly amounts. | Provides 120 days to pay when tax, penalties and interest total less than $100,000. | Payments are due during the agreed period, and a setup fee may apply. |
| Long term installment agreement | Spreads the balance across monthly payments. | The tax bill must be less than $50,000. No prescribed time limit is stated. | A setup fee applies, though low income taxpayers may qualify for a reduced fee. |
The first two options generally involve discussing the case with the IRS, often with help from a tax representative. An offer in compromise receives particular scrutiny: the Centralized Offer in Compromise Unit reviews the taxpayer's finances before deciding whether to accept a lower settlement. A rejection is not necessarily the last step, because the taxpayer may appeal it through IRS Appeals.
Installment agreements have a simpler application route. A taxpayer can apply through the IRS website or mail IRS Form 9465. Before choosing a plan, compare the total balance, including penalties and interest, with the relevant thresholds, and consider whether the monthly payment is manageable. The short term option has a defined 120 day period; the long term option has no stated fixed period, but its balance limit is lower.
Deadlines, records and practical next steps
The IRS generally has 10 years from the date a tax obligation is assessed to take collection steps, or until the balance is paid, whichever comes first. That period is not a reason to put off responding. Penalties and daily compounded interest can continue to add to what is owed, while missed response deadlines can let collection proceed on information that may be incomplete.
Start by opening every IRS notice and identifying the tax year, amount, assessment information and response deadline. If no return was filed, gather income records and prepare the return rather than assuming the SFR includes every available tax break. If a return was filed, compare the notice with your records and confirm that the stated balance is correct.
Next, assess what you can pay without creating undue hardship. A temporary shortfall may point toward currently not collectible status; someone who can make regular payments may examine an installment agreement. An offer in compromise is intended for cases where full payment is unlikely, not simply as a way to request a discount without documenting finances.
Professional assistance can help with a complex return or a negotiation, but free support is also available to some taxpayers. IRS Taxpayer Assistance Centers provide help. As of 2025, the Volunteer Income Tax Assistance program serves people who earn $67,000 annually or less. The Tax Counseling for the Elderly program is available to people age 60 or older.
