The research credit is not refundable, so a loss-making start-up would ordinarily carry it forward for years before seeing any benefit. The payroll tax offset changes that. Qualified small businesses can elect to apply up to US$500,000 a year against payroll tax, using Form 8974, which turns the credit into a reduction of the employer's quarterly payroll tax deposits within months of filing the return.
What it is
An election, made on Form 6765 with a timely filed original income tax return including extensions, to treat a specified amount of the year's research credit as a credit against the employer's share of payroll taxes instead of against income tax. The elected amount is then claimed quarter by quarter on the employment tax return using Form 8974.
| Feature | Rule |
|---|---|
| Annual limit | Up to US$500,000 a year |
| Payroll taxes offset | The employer's share of social security tax, and the employer's share of Medicare tax, each up to US$250,000 |
| Where elected | Form 6765, Section D, on a timely filed original return including extensions |
| Where claimed | Form 8974, attached to Form 941 (or 943 or 944), starting with the first quarter beginning after the income tax return is filed |
| Years available | No more than five tax years |
| Carryforward | Elected credit exceeding the quarter's payroll tax carries to the next quarter |
Who it applies to
A qualified small business is a corporation, partnership or individual with gross receipts of less than US$5,000,000 for the tax year and no gross receipts for any tax year before the five-tax-year period ending with the current year. In plain terms: under US$5,000,000 of gross receipts this year, and no gross receipts at all more than five years ago. Tax-exempt organisations are excluded. Gross receipts are measured on the same basis as for the credit computation and are aggregated across a controlled group.
The second test trips up more companies than the first. A company founded in 2019 with its first revenue in 2020 is in its sixth year of gross receipts by 2025 and no longer qualifies, whatever its size. A company that had a small amount of interest income in an early year may have "gross receipts" earlier than it thinks.
How it works
- Compute the credit on Form 6765 in the ordinary way.
- Elect in Section D the amount, up to the year's credit and up to US$500,000, to apply against payroll tax. The election is on the original return; an amended return cannot make it.
- File the return. The quarter in which the return is filed determines when the offset starts: a return filed in March starts in the quarter beginning 1 April; a return filed in April starts in the quarter beginning 1 July.
- Claim each quarter on Form 8974 with Form 941, up to the employer's share of social security and Medicare tax for the quarter, carrying any excess forward.
- Reduce deposits accordingly; the credit reduces the amount the employer must deposit, which is where the cash benefit arrives.
The elected amount is removed from the income tax credit, so it is not carried forward against income tax as well. Partnerships and S corporations make the election at the entity level and the entity claims the payroll offset, because the entity is the employer.
Worked example
Illustrative example. Alder Diagnostics, a hypothetical start-up founded in 2023 with first revenue in 2024, has 2026 gross receipts of US$1,200,000, a loss for the year, QREs of US$900,000 and no QREs in 2023, so its alternative simplified credit is 6% of US$900,000 = US$54,000. It files its 2026 return in March 2027 and elects to apply the whole US$54,000 against payroll tax. Its employer share of social security and Medicare tax is US$30,000 a quarter.
| Quarter | Employer payroll tax | Credit applied | Carried forward |
|---|---|---|---|
| Q2 2027 (first quarter after filing) | US$30,000 | US$30,000 | US$24,000 |
| Q3 2027 | US$30,000 | US$24,000 | 0 |
Alder receives the whole benefit within two quarters of filing, against payroll taxes it would otherwise have deposited, without waiting to become profitable. It can repeat the election for up to five tax years while it remains a qualified small business.
Common questions
We missed the election. Can we amend? No. The election must be on a timely filed original return.
Can we elect less than the full credit? Yes. Any amount up to the credit and the annual limit; the rest stays as an income tax credit and carries forward.
What if we exceed US$5,000,000 of gross receipts next year? You cannot make a new election for that year, but the offset already elected for an earlier year continues to be applied in the quarters that follow.
Does the limit apply per entity in a group? No. Controlled group members are treated as one for the gross receipts tests and the annual limit.
