Form 8300 penalty calculator

Enter the Forms 8300 you did not file or filed incomplete, the ones you filed late, the cash on the unfiled transactions and the customer statements you did not send, and get the IRC 6721 and 6722 estimate on the per-return figures the Form 8300 manual prints, with the intentional-disregard computation the manual describes.

Forms 8300 not filed, or filed incomplete or incorrect and not corrected

Each transaction (or each time related payments crossed $10,000) is one return. A missing TIN, surname or amount is never inconsequential.

Total cash received on those transactions

Used only for the intentional-disregard computation; the manual measures it per transaction.

Forms 8300 filed late but complete

How late

There is no "by August 1" middle tier for Form 8300.

Annual customer statements not furnished by January 31

When the statements were or will be furnished

Aggregate cash on those statements

For the 6722 intentional-disregard 10 percent computation.

Gross receipts of $5 million or less (small business)

Intentional disregard proposed (Letter 4596)

Which figures this calculator uses, and why they are dated

The Form 8300 manual does not print current penalty amounts. For IRC 6721 it lists $50 per return with a $500,000 annual cap if the failure is corrected within 30 days, otherwise $260 per return, "$270 after 1/1/2019," with a $3,000,000 cap, and "lower caps" for a business with gross receipts of $5 million or less, then sends examiners to a "BSA Policy SharePoint for penalty rates and maximum amounts with inflationary adjustments" (IRM 4.26.10.10.1(5)-(6), Mar. 23, 2020). For IRC 6722 it lists $50 within 30 days ($500,000 cap), $100 by August 1 ($1,500,000 cap), $260 or $270 after ($3,000,000 cap), and for intentional disregard the greater of $500 per statement or 10 percent of the aggregate amount, with no cap (IRM 4.26.10.10.2, Mar. 23, 2020). A separate background section says the 2015 legislation set "$250 per return, with an annual cap of $3 million" and "$500 per form, with no cap" if intentional (IRM 4.26.11.1.1, Feb. 6, 2026); those figures conflict with 4.26.10 and the manual does not reconcile them.

This calculator uses the IRM 4.26.10 figures: $50 and $270 per return for 6721; $50, $100 and $270 per statement for 6722; $25,000 or the cash received up to $100,000 per return for 6721 intentional disregard; $500 or 10 percent for 6722 intentional disregard. The current inflation-adjusted amounts the IRS actually assesses for the year in question are higher and are published in the annual revenue procedure, not in this manual; treat the result as the manual's floor, not the bill. The small-business caps are not printed anywhere in the Form 8300 manual, so the toggle only flags that a lower cap applies; it does not reduce the figure.

How the count works

One return per crossing. Every transaction over $10,000, and every time related or installment payments from the same customer cross $10,000 again, is a separate Form 8300 (IRM 4.26.12.12.1(3)-(5), 4.26.12.10.1(6), Aug. 21, 2019). Even where the examiner accepts one summary return for a customer's whole year, "penalties... should be assessed on the total number of delinquent Forms 8300" (IRM 4.26.11.10.8.1, Aug. 4, 2021).
No August 1 tier and no de minimis exception. "Because Form 8300 is not due February 28/March 15," the middle tier and the small-number exception in the 1099 regulations do not apply to the 6721 penalty (IRM 4.26.10.10.1(8)). The manual does list an August 1 tier for the 6722 statement penalty, and the calculator follows the manual.
Incomplete counts as unfiled. "Failure to complete the form in its entirety is considered an incomplete form and is subject to a penalty" (IRM 4.26.10.7.1(3), Mar. 23, 2020); the TIN, surname and any monetary amount are never inconsequential (IRM 4.26.10.10.1(7)).
Intentional disregard. The greater of $25,000 per return or the cash received in that transaction up to $100,000, with no annual cap (IRM 4.26.10.10.1(9)). The calculator spreads the total cash you enter evenly across the unfiled returns to estimate the per-return amount; if one transaction was much larger than the others, compute it per transaction.
Missing TIN, two solicitations. An initial request at the transaction and one annual request by December 31 (January 31 for December) with the IRC 6723 $50 warning, both documented, and "the penalty is waived" for that return (IRM 4.26.10.10.3.1(6)-(10), July 13, 2012). Take those returns out of the unfiled count.
Statutes. Three years on a filed return; "Penalties may be assessed at any time" on an unfiled one; no statute on the 6722 statement penalty (IRM 4.26.10.11.1, Mar. 23, 2020).

What happens next

The penalty is proposed at the close of an exam by Letter 4595 (no intentional disregard) or Letter 4596 (intentional disregard), each a 30-day letter with a Form 14141 agreement. "Except for the intentional disregard penalties... the business does not have pre-assessment appeal rights"; under a 4595 the business may write and ask for a manager meeting, then is assessed and appeals afterward, while a 4596 carries pre-assessment Appeals, with a small case request at $25,000 or less (IRM 4.26.11.11.3.2(11)-(12), Feb. 6, 2026; 4.26.11.11.3.3, Aug. 4, 2021). Written manager approval is required before any penalty communication (IRM 4.26.11.11.3.1(7), May 29, 2019). Reasonable cause is the business's burden: "The business is required to prove reasonable cause, not the examiner" (IRM 4.26.11.10.8(2)).
