What this means for taxpayers
During the pandemic, the IRS paused much of its automated collection activity. Notices slowed, and lien filings dropped well below their historical levels. These numbers show that period coming to an end.
A Notice of Federal Tax Lien is a public claim against your property — your home, your vehicles, your business assets. It can show up when you try to sell property or apply for credit. A near-10% jump in filings in a single year is not a small swing; it means more taxpayers with unpaid balances are crossing the threshold where the IRS attaches a legal claim.
The revenue figures tell the same story from the other direction. Collecting about $77.6 billion — up roughly 13.6% — while handling more than 5.3 million delinquent accounts shows a system that is working through its backlog and pressing harder on balances that have sat untouched.
Here's the part that matters if you owe: more than $16 billion of that came in through installment agreements, not seizures. Most resolved balances are handled through payment plans and other arrangements, not forced collection. The taxpayers who get the worst outcomes are usually the ones who never respond. If a lien has already been filed against you, federal tax lien help can walk you through the options to release, withdraw, or work around it.

Methodology & source
All figures in this study come directly from the official IRS Data Book, Table 27 — Delinquent Collection Activities, published by the Internal Revenue Service. The IRS Data Book reports activity by federal fiscal year, which runs from October 1 to September 30.
We compared the most recent two fiscal years reported (FY2023 and FY2024) for Notices of Federal Tax Lien filed. The year-over-year percentage changes are calculated from the IRS's own reported totals and rounded for readability. Dollar amounts for collected revenue, delinquent accounts, and installment agreements reflect the FY2024 figures as published. We did not adjust for inflation, and we report only the figures the IRS publishes — no estimates or projections were added.

What is a Notice of Federal Tax Lien?
A Notice of Federal Tax Lien is a public document the IRS files to claim a legal interest in your property when you have an unpaid tax debt. It can attach to real estate, vehicles, and other assets, and it often affects your ability to sell property or get credit. A lien is different from a levy, which is the actual seizure of assets.
