Professional review, without surrendering control

A clearer handoff for you and your CPA.

Koinon Tax can prepare a local review workspace around one tax year. The engagement defines scope; questions stay tied to a snapshot; and proposed changes remain proposals until the owner accepts them.

  • Focused engagement for the tax year under review
  • Review packages connected to the source material
  • Questions attached to the exact reviewed snapshot
  • Proposed changes that stay under the owner’s control

The working set

Tax preparation, planning, and practice finance in one place.

Koinon Tax is built for clinicians whose tax picture rarely fits into a single W-2—and for the professionals helping them make sense of it.

Prepare

Guided federal review

A full 1040 simulation, seven-control reconciliation, required-form list, blocker checks, and exact DIY transfer steps.

Organize

Smart document inbox

Bring tax documents into a watched folder, identify the year and document type, and keep the evidence encrypted and connected.

Plan

Decision scenarios

Compare S-corp, PLLC, sole-proprietor, and C-corp structures alongside salary, retirement, Roth, and estimated-tax choices.

Operate

Books and practice finance

General ledger, financial statements, invoicing, payables, 1099 tracking, budgets, cash flow, net worth, and practice KPIs.

Navigate

Federal and state guidance

A sourced 50-state reference guide, plus detailed preparation support for an initial ten-state matrix that includes Washington.

Review

Traceable professional handoff

Hash-bound packages, questions tied to the reviewed snapshot, and proposals the taxpayer can inspect, accept, or decline.

Built around healthcare income

For employed, independent, and practice-owning clinicians.

The same core workflow handles W-2, 1099, and mixed income. Specialty-aware categories and practice context make the review more relevant without changing the underlying tax logic.
