I owe the IRS money. What actually happens now?
An unpaid balance accrues interest and a failure-to-pay penalty, moves through a sequence of notices, and eventually reaches a final notice that permits the IRS to levy wages and bank accounts. Underneath that, a ten-year collection statute runs from each assessment date. What determines your options is not how much you owe — it is how much of that statute remains on each period, whether every required return is filed, and what your finances look like measured against the IRS's own allowable expense standards. Two people owing the same amount routinely have entirely different correct answers.
What happens to an unpaid balance
It grows, at a compounding rate. The failure-to-pay penalty under § 6651(a)(2) runs at 0.5% of unpaid tax per month to a 25% cap. Interest under § 6601 runs on the tax and on the penalties, compounds daily, and is reset quarterly. Where a return was also filed late, the failure-to-file penalty under § 6651(a)(1) runs at 5% per month — ten times the rate — which is why an unfiled year is a much more expensive problem than an unpaid one. For the months both penalties run, § 6651(c)(1) reduces the failure-to-file addition by the failure-to-pay addition, so it caps out after five months at 22.5% rather than 25%, with the two together reaching 25%.
It moves through a notice sequence. From the first bill through reminders to a final notice before levy. Only the final notice, and a lien filing, carry deadlines you can lose. What each notice means.
It runs against a clock. Section 6502 gives the IRS ten years from each assessment to collect. That clock is the most important fact about most tax debts and the one least often known by the person who owes it.
Why the amount owed tells you so little
It is the number everyone reasons from, and it is close to useless on its own.
Consider two taxpayers who each owe $47,000.
The first has filed every return. The balance was assessed six years ago, so roughly four years of collection statute remain. They earn $95,000, own a home with $140,000 of equity, and have just received a wage levy.
The second has three unfiled years. The IRS prepared substitute returns for them, assessing roughly double the real liability, and the assessments are eighteen months old — nine years of statute remain. They earn $38,000, rent, and own nothing realizable. No final notice has issued.
Same balance. Almost nothing else in common.
The first has significant realizable equity, so an Offer in Compromise will very likely fail the arithmetic — but they can probably pay, and an installment agreement with a levy release is the immediate need. The second’s real liability is probably far lower than $47,000 once the returns are filed, and after that hardship status or a partial pay agreement may resolve most of what remains by simply outlasting it.
No page can tell either of them which is which without knowing those facts.
What determines your options
- Collection statute expiration dates per period, computed with suspensions rather than estimated.
- Filing compliance across all years — which gates the arrangements and frequently changes the balance.
- How each liability was assessed — your return, an adjustment, or a substitute return.
- Income and allowable living expenses under the IRS’s Collection Financial Standards.
- Assets and realizable equity, valued as the IRS values them.
- Penalty composition, and whether abatement is available.
- Current collection status, and whether any deadline is running.
- Prior arrangements, defaults and rejected offers.
- For a business, whether current federal tax deposits are being made.
Possible resolution paths
Every path in federal tax law, and what each turns on: see the full comparison.
- Payment in full — where funds or borrowing exist.
- Installment agreement — payable within the collection period.
- Partial pay installment agreement — some payment possible, full payment not.
- Currently Not Collectible — paying anything prevents basic living expenses.
- Offer in Compromise — collection potential genuinely below the balance.
- Penalty abatement — reduces the balance on independent grounds.
- Correcting the assessment — where the balance is simply wrong.
What should be investigated
- Account transcripts for every period with a balance.
- Collection statute expiration dates per period.
- Filing compliance across all years, including periods assessed by substitute return.
- Penalty composition per period.
- Notice history and current collection status.
- Whether a lien has been filed or a final notice issued.
- Income, allowable expenses, assets and realizable equity.
What to do now
- Find out what the IRS actually has on record, through your online account or an account transcript, rather than working from the most recent letter.
- Deal with unfiled years first. They carry the heaviest penalties and they gate everything else.
- Get collection statute dates computed. They frequently decide the path by themselves.
- Do not choose a resolution from the balance.
- Act before a final notice issues, while the options are widest.

Common questions
Does owing more than a certain amount change what happens?
- Thresholds do exist, but they affect process rather than outcome. Balances below certain levels qualify for installment agreements granted without a financial statement; above them a documented financial position is required. Very large balances are more likely to be assigned to a revenue officer and to attract a lien filing. None of these thresholds determine whether an option is available to you — that is decided by the collection statute, your finances, and filing compliance.
Can the IRS take my house?
- Seizure of a principal residence is possible but rare and heavily constrained: it requires written approval of a federal district court judge or magistrate under Internal Revenue Code section 6334(e). Far more common is a filed Notice of Federal Tax Lien, which does not take the house but attaches to it and must generally be dealt with before a sale or refinance completes.
What happens if I just do nothing?
- Interest and penalties accrue, the notice sequence continues, and a final notice eventually permits levy of wages and bank accounts. Meanwhile the collection statute keeps running, which is the one element working in your favor. Whether doing nothing is catastrophic or nearly optimal depends almost entirely on how much statute remains and on whether you have income or assets the IRS can reach — which is exactly why the answer cannot be given generically.
