Every year, the federal government provides billions of dollars in R&D Tax Credits to reward companies that innovate, improve products, develop software, streamline processes, or solve technical challenges.
Yet most eligible businesses never claim the credit — often because they assume they don’t qualify.
If your company designs, builds, develops, tests, or improves products, software, manufacturing processes, or internal operations, you may be eligible for a significant dollar-for-dollar reduction in federal taxes.
Don’t leave money on the table. Find out if your business qualifies in just a few minutes.

I was encouraged to apply through other founders and they were absolutely right. It took me no more than 3 minutes to sign up, integrate with my payroll system, and receive notice that we were to receive the R&D tax credit. The team was incredibly responsive with follow-up questions, addressing my concerns re: audit and financials, and giving us cash now vs. a year later. Looked at other companies and no other ones provided such a level of responsiveness and immediate payment.
Mainstreet saved our company. In the middle of the pandemic they were able to give us back 6 months of runway that we otherwise would have never had, and saved 18 jobs. They are the best service I’ve ever used.
We are having an amazing experience with Mainstreet. They are exceptional domain experts, provide awesome support and really know what they are doing. We looked at several options but Mainstreet was the obvious choice. They found free money for our start-up and then even advance it at no extra cost. On top of that, you get complete audit protection — it is really a complete no brainer.
