When you owe back taxes, IRS letters, agreements, and collection actions all use specific legal and financial terminology. Knowing the difference between a lien and a levy, or between an installment agreement and an offer in compromise, can change how you respond and which resolution options you pursue. The definitions below cover the terms taxpayers encounter most often when they owe the IRS.
Common IRS Tax Terms

Explore Your Resolution OptionsCollection ActionsPenalties & DeadlinesFederal Tax Lien
A legal claim the government places against your property when you neglect or fail to pay taxes you owe. A lien can affect your assets, credit, and ability to sell property.
Tax Levy
The actual seizure of property to collect unpaid taxes. Unlike a lien, which is a claim, a levy allows the IRS to take assets such as bank funds, wages, or other property.
Wage Garnishment
A type of levy in which the IRS requires your employer to withhold a portion of your paycheck and send it directly to the IRS until what you owe is resolved.
Installment Agreement
A payment plan that allows you to pay what you owe in monthly installments over time rather than in a single lump sum. Interest and penalties may continue to accrue.
Offer in Compromise
An IRS program for qualifying taxpayers who can't pay their full tax balance, based on ability to pay, income, expenses, and asset equity.
Currently Not Collectible
A status the IRS may grant when paying what you owe would create financial hardship. Collection activity is temporarily paused, though the balance remains and interest continues.
Penalty Abatement
The removal or reduction of penalties for taxpayers who qualify, often through first-time abatement or by demonstrating reasonable cause, such as illness or disaster.
Innocent Spouse Resolution
Resolution options that may release you from responsibility for tax, interest, and penalties caused by a spouse or former spouse who improperly reported items on a joint return.
Collection Statute Expiration Date
The deadline for the IRS to collect unpaid tax, generally 10 years from the date the tax was assessed. Certain events, like bankruptcy or an OIC, can extend this period.
Trust Fund Recovery Penalty
A penalty assessed against individuals responsible for collecting and paying employment taxes who willfully fail to do so. It can apply personally to business owners and officers.
Substitute for Return
A return the IRS files on your behalf when you fail to file. An SFR typically excludes deductions and credits you may be entitled to, often resulting in a higher tax bill.
Collection Due Process Hearing
A hearing you can request after certain IRS notices, giving you the opportunity to dispute a lien or proposed levy and present collection alternatives before an independent office.
