Why an Enrolled Agent?

An Enrolled Agent is a federally credentialed tax professional authorized to represent taxpayers before the IRS.

Elizabeth holds that credential. It is the practical reason GTS can prepare a return, then stay with the same matter if the IRS or a California agency asks questions about it.

  • Individual and business tax knowledge applied across return types
  • Tax planning during the year, not only at filing
  • Representation before the IRS on examinations, appeals, and collection matters
  • Continuing-education requirements to maintain the credential
  • Professional-conduct standards established by the IRS (Circular 230)
  • Year-round federal tax assistance rather than seasonal-only availability

What the credential is not

Elizabeth is an Enrolled Agent — not a CPA and not an attorney. GTS does not provide legal services, investment management, or comprehensive financial planning. When a matter needs those professionals, we say so and work alongside them.

You can verify the standing of any federally authorized tax practitioner through the IRS directory of federal tax return preparers.

Communication is part of the service

You should never have to wonder whether your return—or your question—fell through the cracks.

Clients tell us the hardest part of tax work is not knowing where things stand. These are the checkpoints we build into every engagement.

  • Immediate confirmation when your inquiry arrives
  • A named primary contact for your engagement
  • Confirmation when your documents are received
  • A clear list of anything still missing
  • An explanation of the expected preparation or response stage
  • Status updates while the work is in progress
  • Notification when the work is ready for you
  • Clear next actions on your side
  • Defined expectations for how questions are answered
  • Secure message history retained inside ClientHub

About timing

Preparation and response timing depends on the return type, the completeness of your records, and any agency deadline involved. We tell you the expected stage for your specific engagement rather than publishing a blanket turnaround promise.
