MAINSTREET TAX CREDITS

Credit where credit is due — literally.

97% of U.S. startup tax credits go unclaimed, leaving billions of allocated government funds on the table every year.

We demystify these complex systems so that you can claim
thousands of dollars for the work you're already doing.

The average venture-backed startup saves $50,000+ in its first year. 💰

R&D Tax Credits:
A brief history

The Federal R&D Credit is designed to incentivize companies who bring new products to market. Think of this program as the IRS’s way of rewarding businesses that prioritize innovation.

Startups and Fortune 500 companies alike claim billions of dollars a year in R&D tax credits — but the process to access this money is complex and time-consuming.

That's where MainStreet comes in. We take the guesswork (and the legwork) out of tax credits and pass the savings onto you. 

HOW IT WORKS

Let us help you get what you're owed

1

Qualify

Plug your payroll system into our dashboard and complete a quick survey to get started.

We'll scan through hundreds of federal, state, and local credits and match you with the ones most beneficial to your business.

2

Claim

Come tax season, we'll do all the paperwork — and let your CPA take all the credit.

We'll prepare the necessary forms, including a detailed R&D Qualified Research Expenses (QRE) Summary and Form 6765.

3

Collect

When it comes time to file, have your CPA submit the prepared forms alongside your yearly tax return.

The IRS will process your claim and send you the money you're owed. Easy as that.
