Solo practices — one credentialed accountant

Where most small businesses end up. You deal with the person doing the work — and with their holiday schedule. Columbus has 190 of them.

Showing 24 of 190, alphabetically.

Small firms — 2–5 CPAs

Cover for each other through filing season, still small enough that a partner knows your file. Columbus has 42 of them.

Showing 16 of 42, alphabetically.

Mid-sized firms — 6–20 CPAs

Specialists on staff for anything unusual: multi-state, audits, valuations. Columbus has 9 of them.

Large and national firms — 21 or more CPAs

Listed for completeness. Minimum engagements here run into five figures and most do not take small-business clients at all. Columbus has 3 of them.

Firms with a phone number on file only — without one the listing cannot be acted on. Order inside each group is alphabetical: the IRS records a credential, not the quality of the work, and we have no basis to rank.

Which size fits you

The four big names at the bottom of this page audit listed companies. They will not file a return for a plumbing business, and their minimum engagement is larger than most small firms bill in a year. Listing them is completeness, not a suggestion.

For a business under a few million in revenue the real choice is between a solo practice and a small firm. A solo is cheaper and knows your business personally; the risk is that one person is also one point of failure in March. A firm of three to five costs more and covers that, which is what you are paying the difference for.

The Columbus market in numbers

Why the two counts differ. The list above covers the city of Columbus and comes from the IRS, which records every credentialed accountant including sole practitioners working from home. The table covers the whole Columbus, OH Metro Area and comes from the Census, which counts only businesses with paid employees. Different areas, different definitions — they are not meant to match.

At 12.5 employees per establishment, Columbus is a market of mid-sized practices. Nationally the same code averages 10.5 (mid-sized practices), so firms here are larger than typical — which is the clearest signal of what you will be quoted.

Licensed CPA practices — audit, assurance, tax planning and advisory.

How do I check that an accountant is actually licensed?
