Tax and IRS terms, explained plainly.
No jargon, no fine print. Just what these terms actually mean, grouped by where you're likely to run into them.
Records and documents
- Account transcript
- An IRS record showing the full transaction history for a tax year, including assessments, payments, penalties, and interest.
- Return transcript
- An IRS record showing most line items from your originally filed return, as the IRS processed it.
- Wage and income transcript
- An IRS record showing income reported to the IRS by employers and other payers, such as W-2s and 1099s.
- Record of account
- A combined document that includes both the account transcript and the return transcript for a single tax year.
- Transcript
- A general term for any summary of tax return or account information the IRS makes available to taxpayers.
Balances, penalties, and interest
- Assessment
- The formal recording of a tax liability by the IRS after a return is processed or a substitute return is prepared.
- Failure-to-file penalty
- A penalty charged when a required tax return is filed after its due date.
- Failure-to-pay penalty
- A penalty charged when tax owed is not paid in full by its due date, regardless of when the return was filed.
- Substitute for Return (SFR)
- A return the IRS prepares on a taxpayer’s behalf when a required return goes unfiled, generally without deductions or credits the taxpayer might otherwise claim.
Notices and collection
- CP14
- The IRS notice sent when a processed return shows a balance due — typically the first notice in a collection sequence.
- CP2000
- A notice sent when income reported to the IRS by a third party does not match what was reported on a filed return.
- CP504
- A more urgent notice warning that the IRS may levy a state tax refund or other assets if a balance remains unpaid.
- Lien
- A legal claim the IRS places against property when a tax debt goes unpaid, which can affect the ability to sell or refinance that property.
- Levy
- The actual seizure of property or funds — such as wages or a bank account balance — to satisfy an unpaid tax debt.
- CSED
- Collection Statute Expiration Date — the date after which the IRS generally can no longer legally collect a specific tax debt.
Resolution options
- Offer in Compromise
- An agreement that lets a taxpayer settle a tax debt for less than the full amount owed, based on demonstrated inability to pay in full.
- Installment agreement
- A payment plan that lets a taxpayer pay an outstanding balance over time instead of in one lump sum.
- Currently not collectible
- A status the IRS can assign to an account when a taxpayer demonstrates they cannot currently pay, which pauses active collection.
