R&D Tax Credit for Startups

Some qualified small businesses may elect to apply a portion of the research credit against payroll taxes rather than income taxes. Eligibility, the elected amount, and the timing rules are specific to the taxpayer.

Under the PATH Act of 2015 (updated by the Inflation Reduction Act of 2022), qualifying small businesses can elect to apply up to $500,000 of R&D credits per year against their portion of Social Security payroll taxes (the employer's 6.2% FICA obligation).

To use the payroll tax offset, your business must meet both criteria:

1. Gross receipts under $5 million in the current tax year
2. No gross receipts in any year before the 5-year period ending with the current tax year (i.e., the business is less than 5 years old with revenue)

These tests include aggregation and other rules. A business that does not qualify for the payroll-tax election may still need tax-professional advice about other research-credit treatment.

The maximum payroll tax offset is $500,000 per year (increased from $250,000 by the Inflation Reduction Act of 2022).

The maximum election is not a guaranteed benefit. The available credit can be limited by the current-year research credit, the election, carryforward rules, payroll-tax mechanics, and the taxpayer's facts. A qualified professional should calculate the result and timing.

1. Calculate the research credit on the current Form 6765.
2. Make the payroll-tax election only if the taxpayer qualifies and within the timing rules for the originally filed return, including extensions.
3. Complete Form 8974 with the employment tax return when applicable.
4. Confirm timing and deposit treatment with the tax professional or payroll provider.

The current Form 6765 instructions describe the election, employer Social Security liability, aggregation, and carryforward rules.

• Not claiming because "we're not profitable." — The payroll tax offset exists specifically for this situation.
• Assuming a payroll-tax election can be made after the original-return deadline. — The election has specific timing rules.
• Treating a reconstructed record as a substitute for review. — Later evidence may help, but its value depends on the facts and support.
• Assuming a software product qualifies because it has technical uncertainty. — All elements and exclusions still require review.
