Learn moreHow it works
Simple, personal and direct
- Say hello. Text or call. You speak with your CPA, not a call center.
- Tell us what you need. A return, a letter you received, books that need catching up, or a decision you want to get right.
- Send your documents. We give you a checklist so nothing is missed. Start with our tax document checklist.
- We prepare and review. You get a clear explanation of the result and anything to watch for next year.
- File and plan ahead. We file, then stay available year-round for questions, estimates and planning.

How much does it cost?
At Merit One CPA, we take a personalized approach to ensure you receive the right level of service for your needs. Our fees depend on the complexity of your tax situation and the services you need. We’re happy to learn about your situation and provide a customized quote before we get started.
Can you help with both my personal and business taxes?
Yes. Many clients have us prepare their individual return alongside their business return and books, so everything fits together.
Do you work with clients year-round or only at tax time?
Year-round. Planning in the fall, estimates through the year, bookkeeping every month and help when a letter arrives.
