Nationwide service from one connected team.
Bookkeeping, tax, advisory, and IRS representation for clients anywhere in the country, delivered through a secure online workflow.
TreeStar Solutions serves clients across the United States from our California offices. Enrolled Agents are federally authorized to represent taxpayers before the IRS no matter where those taxpayers live, and our secure client portal, e-signatures, and video meetings make distance a small detail. We work with professional gamblers who play in several states, regulated businesses operating across state lines, real estate investors with property in more than one state, and California businesses expanding elsewhere. Your bookkeeping, tax, and advisory stay connected wherever you are, and we review the filing requirements in each state where you do business.

Common questions
Can you represent me before the IRS if I live outside California?
Yes. Enrolled Agents are federally authorized to represent taxpayers before the IRS regardless of where they live, so your location does not limit our IRS representation.
Do you prepare state returns for other states?
Yes, in many situations, including nonresident returns and businesses that operate in more than one state. We review your filing requirements in each state as part of the engagement.
How do we work together if we never meet in person?
Everything runs through our secure TaxDome client portal: document exchange, e-signatures, and messages, with phone and video meetings on a schedule that fits yours.
