The R&D Payroll Tax Credit: How Startups Get Up to $500,000 a Year

What the payroll tax election is

A qualified small business can elect to apply part of its federal R&D credit against the employer's share of payroll taxes, rather than income tax. Since 2023 the annual limit is $500,000: up to $250,000 against the employer's Social Security tax and, since the Inflation Reduction Act, up to a further $250,000 against the employer's Medicare tax.

Who qualifies

For the tax year you make the election, your business must:

• Have gross receipts of less than $5 million for the year, and
• Have had no gross receipts for any tax year before the five-year period ending with that year (in plain terms, you're within roughly your first five years of revenue).

The election can be made for up to five tax years. Corporations, partnerships and LLCs can all qualify, and so can pre-revenue companies.

What counts as qualifying research

The work must meet the same four-part test as the regular credit: a permitted purpose, technological in nature, eliminating technical uncertainty, through a process of experimentation. For startups this commonly includes:

• Building a new software platform, app or algorithm
• Developing hardware, devices or prototypes
• Machine learning and data engineering
• Formulating new food, beverage, cosmetic or chemical products
• Engineering new manufacturing methods

How to claim it

1. Calculate the credit for the year on Form 6765, supported by a documented study of qualifying wages, supplies and contractor costs.
2. Make the election on your timely filed income tax return, including extensions.
3. Apply it to payroll using Form 8974 with your quarterly Form 941, starting with the first calendar quarter after you file the income tax return. Any unused amount rolls forward to later quarters.

Illustrative example

Common mistakes

• Missing the election. It must be made on a timely filed original return, including extensions.
• Waiting too long. Once you pass the five-year window or $5 million of receipts, the payroll option ends.
• Thin documentation. Keep sprint notes, tickets, commit history, design documents and time records that tie work to projects.
• Forgetting states. Several states offer their own R&D credits, some refundable.
