Tax Services connected to your books.
For business owners and families who want tax work that starts from clean numbers and continues all year, not just in April.
TreeStar's tax services are led by Enrolled Agents and built on the same information that runs your bookkeeping and payroll. That connection matters. When the books are current, planning conversations happen before decisions are made, returns reflect what actually happened, and questions from a taxing agency have a clear paper trail behind them. We prepare business and individual returns, plan ahead with you through the year, review prior filings for missed items, and represent you before the IRS when a notice arrives. Clients across California and nationwide work with us through the TaxDome portal for secure document exchange and e-signatures.

Common questions
Do I need TreeStar to keep my books to use your tax services?
No. Many clients start with tax only. When we also keep the books, planning and preparation tend to move faster because the numbers are already reconciled.
Who prepares my return?
Tax work at TreeStar is EA-led. Enrolled Agents are federally authorized tax practitioners with unlimited rights to represent taxpayers before the IRS.
Do you work with clients outside California?
Yes. TreeStar has offices in Chico, Garberville, Sacramento, and San Francisco and serves clients nationwide through a secure online portal.
