TL;DR:
Filing taxes is broken. The system is complicated, expensive and anxiety-inducing. The whole thing feels like a racket.
You wind up paying someone, a preparer or a piece of software, simply to get through the process. And if anything goes wrong, the IRS or your state will be quick to let you know. Or worse, they'll be slow to let you know. Then you're left digging up docs from three years ago to find answers.

We’re building Prime Meridian to do your taxes, for free.

Free? What’s the catch?
There’s a dime-a-dozen “free” tax solutions. And none of them are truly free. That’s why most people end up paying.

They’re either:
Too complicated: you’re expected to know the tax code like the back of your hand
Too restrictive: great if you’re a simple W-2, not great if you’re not
Too incomplete: they’ll cover federal, but you’re left to solve state and local by yourself
Prime Meridian doesn’t play by those rules.

Sounds too good to be true.
How’s this working?
We’ve built a state-of-the-art tax AI, getting 100% on TaxCalcBench. You can read our paper here.
Humans can’t read or reason over the entire tax code. But modern AI systems can: consistently and at scale.
And the beauty of AI: once a system can do something, it won’t unlearn. We’ve already shown what they can do. Personal tax prep capabilities are headed in one direction. You can see the cost curves of AI below.

Now that AIs can do this, the cost of tax prep is going to follow the cost of tokens and end up at zero.
We’re entering a world where premium tax services are going to be free and ubiquitous. Everyone uses Google independent of net worth, premium and free are synonymous with search and we’re going to make tax prep the same.
Anything I can try? 100%. We know we're claiming a lot. So try us out with your taxes for 2025 here.
And who are you?
We’re two second-time founders.
Saket previously founded a financial services company that raised $15M and managed tens of millions of dollars for businesses. Prior to that he worked in venture capital and investment banking.
Rishabh most recently worked on the technical staff at xAI, working on Grok 4. Prior to that he was in Google working on ML research and engineering in the Ads team.
