# CPAs in Mercer Island, Washington — 142 in practice

> Every certified public accountant licensed by Washington State and on the record in Mercer Island: 142 in practice, with licence numbers and renewal years. Board of Accountancy data, collected 2026-08-21.

## CPAs in Mercer Island

**142** certified public accountants are licensed to practise and on the Board’s record in Mercer Island — 0.5% of everyone Washington currently licenses.

### What the address on the record means, and what it does not

The Board records one place per licence holder. It is where the Board
writes to them — not necessarily where they practise, and not a list of
firms in Mercer Island. Someone with a Mercer Island address may serve clients across
the state, and a firm in Mercer Island may be staffed by CPAs recorded elsewhere.

Read against that limit, the number is still worth something: it says how
many people Washington currently licenses with a Mercer Island address, which is
the closest a public register gets to the size of the local profession.

### When they renew

Washington renews CPA licences **every three years**, between
1 January and 30 April. That splits Mercer Island into cohorts:

| Renews by 30 April | CPAs in practice | Share |
|---|---|---|
| [2027](/city/mercer-island/renewal-2027.md) | 52 | 36.6% |
| [2028](/city/mercer-island/renewal-2028.md) | 52 | 36.6% |
| [2029](/city/mercer-island/renewal-2029.md) | 38 | 26.8% |

The deadline that actually bites is earlier: the 120 hours of continuing education must be complete by **31 December of the preceding year**. [How the three-year cycle works](/renewal.md).

### How long they have been licensed

32 of the 142 CPAs on the record in Mercer Island were first licensed before 2000 — 22.5%. By decade of first licence:

| First licensed | CPAs in practice | Share |
|---|---|---|
| 2020s | 33 | 23.2% |
| 2010s | 39 | 27.5% |
| 2000s | 38 | 26.8% |
| 1990s | 16 | 11.3% |
| 1980s | 11 | 7.7% |
| 1970s | 3 | 2.1% |
| 1960s | 2 | 1.4% |

### Board orders

None of the 142 licences held in Mercer Island has a Board order published against it. Note what that does and does not mean: the Board has published orders as documents only since 1 January 2020, so an older matter would not show here at all.

### Looking for a CPA in Mercer Island?

A licence is the legal minimum to practise, not a recommendation, and this site makes none. Tell us what you need and we pass the enquiry to people holding a current Washington licence — 142 of them are on the record in Mercer Island.

We vouch for nobody, and we have no arrangement with any firm today — we are collecting these requests in order to go and find them. How we are paid is on the [privacy page](/privacy.md).

### Registered CPA firms in Mercer Island

Alongside the 142 individually licensed CPAs, the Board lists **13** registered CPA firms with a Mercer Island address. The two registers are separate: a firm registration is not a licence held by any person, and the file does not say who works where.

6 of them — 46.2% — are **sole proprietorships**: one person practising under a trading name, with no separate entity behind it. Worth knowing before picturing an office. [What each legal form means](/firm.md).

| Legal form | Firms here | Share |
|---|---|---|
| [Sole Proprietorship](/firm/sole-proprietorship.md) | 6 | 46.2% |
| [P.S. Corporation](/firm/p-s-corporation.md) | 4 | 30.8% |
| [Limited Liability Company](/firm/limited-liability-company.md) | 3 | 23.1% |
