Choosing a Business Structure for a Tax or Accounting Practice

Professionals who advise on entity choice still have to make it for themselves. For a tax or accounting practice, the analysis has a few wrinkles worth spelling out.

The Realistic Options

• Sole proprietorship — simplest start, no liability shield, full self-employment tax. Fine for a side practice; outgrown quickly.
• LLC — the flexible default: liability protection with any tax treatment you choose, including an S election later. Note that some states restrict how licensed professionals may organize — check your state’s professional-entity rules via its business portal.
• S corporation — at steady profits above a reasonable salary for your role, the self-employment tax savings become significant; below that, the payroll overhead isn’t worth it.
• Partnership — for multi-owner practices, with partner agreements doing the heavy lifting on compensation and exits.

Practice-Specific Considerations

Professional liability doesn’t disappear behind any entity — malpractice insurance still matters. Seasonality argues for the LLC’s flexibility early on. And your own estimated taxes deserve the same discipline you’d prescribe a client.

Frequently Asked Questions

Is there one ‘best’ structure for a tax practice?

No single answer — it depends on profit level, owners, and state professional rules. The honest version of ‘best’ is ‘best for your numbers this year, with room to change.’

When does the S election start making sense?

When profits consistently exceed a reasonable salary for the work you do — that’s when distributions begin escaping self-employment tax.

Can I switch structures later?

Yes — LLCs in particular can change tax treatment as you grow, which is why they’re the common starting point.

Does an entity protect me from malpractice claims?

Not from your own professional errors — that’s what insurance is for. Entities shield other business liabilities.

Should a solo practice bother with an entity at all?

Usually yes, for the liability shield and the optionality. Our start-up guide walks the sequence; contact us to run your numbers.
