Online CPA Services in All 50 States
OICPA is an online CPA firm serving clients in all 50 states. Here is how working with us works, wherever you are.
How OICPA works online
All 50 states, fully online
Estimates, onboarding, document upload, meetings, and signatures all happen online - wherever you live or run your business.
Price it yourself first
Free calculators and an instant pricing tool show what a service costs and what it could save before you ever book a call.
State-by-state rules handled
Multi-state income tax, sales tax nexus, payroll registrations, and state PTET elections are part of the work, not an add-on.
A dedicated CPA, online
Every engagement has a CPA who knows your file, reached by video and secure messaging instead of an office visit.
