IRS Failure to File vs Failure to Pay Penalties: What the Data Shows (2026)

By Angeline Balsitis, EA · Reviewed by Melissa Ly, Chief Tax Officer · Updated July 3, 2026 · Editorial Standards

You may be sitting on a return you never filed because you couldn't pay the balance — and telling yourself that filing late is the smaller sin. The IRS data says the opposite. When you compare IRS failure to file vs failure to pay penalties side by side, the penalty for not filing is ten times harsher per month, and in raw dollars it out-totaled the failure-to-pay penalty in FY2023 despite hitting a fifth as many taxpayers.

This study pulls the exact figures from the IRS Data Book so you — or a reporter citing this page — can see the gap in one place. The math is simple and the takeaway is blunt: if you can only do one thing by the deadline, file.

Key findings: IRS failure to file vs failure to pay penalties

The failure-to-file penalty is the single most expensive individual civil penalty in the IRS system on a per-assessment basis. These are the FY2023 figures, straight from IRS Data Book Table 28:

• The IRS assessed $20.68 billion in failure-to-file (delinquency) penalties against individuals, estates, and trusts in FY2023, across 3,292,863 penalties.
• It assessed $14.87 billion in failure-to-pay penalties over the same period, across 18,599,109 penalties.
• The failure-to-file penalty averaged roughly $6,281 per assessment — about eight times the roughly $800 average failure-to-pay penalty.
• Failure-to-file penalties out-totaled failure-to-pay penalties by nearly $6 billion despite being assessed only about one-fifth as often — the direct result of the 5%-per-month rate versus 0.5% per month.
• The IRS abated about $1.14 billion in failure-to-pay penalties against individuals, estates, and trusts in FY2023, across roughly 2.42 million abatements — proof these penalties are frequently removed when taxpayers ask and qualify.
• By FY2025, individual failure-to-pay penalties had climbed to 24,251,980 assessments worth $12.09 billion, while individual delinquency (failure-to-file) penalties totaled $6.48 billion.

Read that table twice. The failure-to-pay column has more than five times as many penalties, yet the failure-to-file column carries the bigger dollar total. That is the whole story of this study in two rows.

Why failing to file costs 10x more than failing to pay

The gap comes entirely from the penalty rates written into the tax code. The failure-to-file penalty runs at 5% of the unpaid tax per month (or part of a month), while the failure-to-pay penalty runs at just 0.5% per month. Both cap at 25% of the unpaid tax, but the file penalty reaches that ceiling in five months while the pay penalty needs roughly 50 months to get there.

When both penalties apply in the same month, the IRS reduces the failure-to-file penalty to 4.5% so the combined rate is 5% — but that combined rate is still nine times the pay-only penalty. The lesson holds: the expensive mistake is not filing, not the inability to pay.

This is also why the totals diverge so sharply. Far fewer people fail to file than fail to pay, but each failure-to-file penalty is so much larger that the smaller group generates the bigger bill. For the full breakdown of how these penalties stack up against every other type, see our study on IRS penalties by type for individual taxpayers.

How the numbers shifted by FY2025

The failure-to-pay penalty count grew while the delinquency total fell sharply between FY2023 and FY2025. Failure-to-pay assessments rose to more than 24 million even as the dollar total dipped, and the failure-to-file total dropped from $20.68 billion to $6.48 billion — a reminder that year-to-year penalty totals swing with filing behavior, pandemic-era relief unwinding, and enforcement timing.

Note the two-year comparison mixes source tables (Table 28 for FY2023, Table 4-2 for FY2025), so the FY2023 figures cover individuals, estates, and trusts while the FY2025 figures are the individual series. The directional story — file penalties are the costlier ones per event — holds across both years.

What this means for you, in plain English

If you can't afford your tax bill, filing on time is the cheapest move you can make. Filing shuts off the 5%-per-month failure-to-file penalty and leaves only the 0.5%-per-month failure-to-pay penalty plus interest — a fraction of the cost. The $20.68 billion in FY2023 delinquency penalties represents money that, in large part, taxpayers would not have owed if they had simply filed and dealt with the balance separately.

The second takeaway: penalties are negotiable more often than people think. The IRS removed over a billion dollars in failure-to-pay penalties in a single year. If you have a clean recent compliance record, First-Time Abate can wipe the penalty out — and the new Automatic Exemption from Penalty, rolling out in summer 2026, applies this relief automatically without a request. Reasonable-cause relief covers illness, disaster, and other events outside your control. Our broader look at how often the IRS removes or abates penalties puts the odds in context.

If you have unfiled years stacking up, the delinquency penalty is the reason to move now, not later — every additional month of non-filing adds 5% until it caps. Our guide to unfiled tax returns walks through the order to file them in.

A worked example: what the rate gap costs

Here is a clearly hypothetical case to show the arithmetic. Say you owe $10,000 and you're five months late, having filed nothing and paid nothing:

• Failure-to-file penalty: 5% per month for five months = 25% (the cap) = $2,500. Because the failure-to-pay penalty also applies each of those months, the file penalty is reduced to 4.5%/month, so it lands around 22.5% = $2,250.
• Failure-to-pay penalty: 0.5% per month × 5 months = 2.5% = $250.
• Combined penalties: roughly $2,500 — before interest.

Now run the same five months if you had filed on time but still couldn't pay: only the failure-to-pay penalty applies — 0.5% × 5 = 2.5% = $250. Filing that one return on time saves about $2,250 on a $10,000 balance. You can estimate your own exposure with our IRS penalty and interest calculator (it estimates; it never promises a figure).

Methodology & source

All FY2023 figures in this study come directly from the IRS Data Book, Table 28 — Civil Penalties Assessed and Abated, by Type of Tax and Type of Penalty, for the individual, estate, and trust category. Dollar amounts are reported by the IRS in thousands and are restated here in billions ($14,874,227 thousand = $14.87 billion; $20,678,979 thousand = $20.68 billion). Average-per-penalty figures were calculated by dividing the amount assessed by the number of penalties assessed; no other values were derived or estimated. FY2025 comparison figures come from the IRS Data Book FY2025, Table 4-2, and reflect the individual series (individuals only), which is why they are not directly line-for-line with the FY2023 individual/estate/trust figures. "Amount assessed" reflects penalties charged during the fiscal year, not amounts ultimately collected or net of later abatements. You can review the primary source here: IRS Data Book, Table 28 — Civil Penalties Assessed and Abated.
