If you’re a startup founder or finance leader, you may have heard that R&D tax credits can help offset payroll taxes. But can these credits be used for both federal and state payroll taxes, or only federal? Here’s what you need to know:

Federal Payroll Tax Offset

The federal R&D tax credit is especially valuable for early-stage companies that aren’t yet profitable. Thanks to recent legislation, qualified small businesses can use the federal credit to offset up to $500,000 of their federal payroll tax liability per year.

Key facts:

  • Only the employer’s share of Social Security and Medicare taxes (FICA) can be offset.
  • The credit is available to companies with less than $5 million in gross receipts and within five years of their first gross receipts.
  • The offset applies only to federal payroll taxes, not to any state payroll tax obligations.

What About State Payroll Taxes?

Here’s where things get tricky:

  • The federal R&D tax credit cannot be used to reduce state payroll tax liabilities.
  • Each state has its own payroll tax system, and federal credits do not transfer over.

State R&D Credits

Many states offer separate R&D tax credits, but these programs are distinct from the federal version.

Consider:

  • State R&D credits typically offset state income or franchise taxes.
  • A few states offer refundable credits or allow credits to offset other state-level business taxes.
  • The rules, eligibility, and application processes vary widely by state.

Best Practices

  • Track and claim federal and state credits separately.
  • Consult a tax advisor to maximize your benefit and avoid compliance pitfalls.
  • Stay updated on both federal and state legislation, as rules can change.

So remember, you can use R&D tax credits to offset federal payroll taxes, but not state payroll taxes. State R&D credits exist, but they generally do not apply to payroll taxes.
