vetted CPAs for Startups (2026) Most CPAs file taxes. Startup CPAs file taxes and help you not leave $50,000 on the table in R&D credits, set up your equity compensation structure before it becomes an expensive problem, and make sure your books are clean enough that a Series A investor doesn't slow-walk the deal because of a revenue recognition question. The difference matters most in the first three years. The entity structure you choose, the accounting method you set up, the R&D credit documentation you start or don't start—these decisions are expensive to fix later and cheap to get right early. We reviewed 50+ CPA firms serving early-stage and growth-stage startups. The five below specialize in exactly this client profile. They've seen your specific problems before and know how to solve them. R&D Tax Credits: The $50K Question Most Startups Miss Before you look at any CPA firm, understand this: the federal R&D tax credit under Section 41 provides a credit of up to 20% of qualified research expenses.

Frequently asked questions

What is Sam's List?

Sam's List is a curated directory of vetted financial professionals including accountants, CPAs, financial advisors, bookkeepers, and fractional CFOs. We help business owners and high net worth individuals find the right professional through verified reviews, detailed profiles, and a matching quiz that connects you with professionals based on your needs, industry, and financial profile.

How does Sam's List vet the professionals on the platform?

Every professional on Sam's List goes through a review process before being listed. We review their credentials, confirm they are actively practicing, and monitor their client reviews over time. Unlike directories that let anyone pay to be listed, we maintain quality standards so the professionals you see are legitimate and reputable.

Are the reviews on Sam's List real?

Yes. Every review on Sam's List is submitted by someone who has interacted with that firm. We do not allow firms to remove negative reviews or manipulate their ratings. Every reviewer must authenticate through LinkedIn, Google, or Twitter before submitting a review. No anonymous reviews are allowed.

How is Sam's List different from other financial professional directories?

Most other platforms take 5-10% of your annual contract when you hire a firm through them, sometimes in perpetuity. Sam's List takes zero referral fees and zero commissions. Our reviews are verified through social authentication and cannot be removed by the firm, and our matching quiz recommends professionals based on your specific situation rather than who paid the most for visibility.

Does it cost anything to use Sam's List?

No. Sam's List is completely free for anyone searching for a financial professional. You can browse profiles, read reviews, take the matching quiz, and contact professionals at no cost.
