How to choose an accountant in Rancho Cucamonga

  • Verify credentials — a CPA holds a state Board of Accountancy license; a tax preparer should have a valid IRS PTIN and, ideally, an EA (Enrolled Agent) designation.
  • Match the specialty to your needs — small-business tax, S-corp/LLC filings, bookkeeping, or personal returns are different skill sets.
  • Confirm they e-file and use current software, and ask how they handle IRS notices or audits.
  • Get the fee structure in writing — hourly, flat per-return, or monthly retainer — before engaging.
  • Ask for an engagement letter defining scope, responsibilities, and deadlines.
