Tax preparation services in Washington, DC
278 firms in Washington employ someone the IRS credentials to prepare returns, and 211 of them are one-person practices. Grouped below by size, smallest first — because that is the shelf most people actually need.
Why the two counts differ. The firm list on this page covers the city of Washington and comes from the IRS, which records every credentialed accountant, including sole practitioners working from home. The Census figures cover the whole Washington-Arlington-Alexandria, DC-VA-MD-WV Metro Area and count only businesses with paid employees. Different areas, different definitions: the two numbers are not meant to match.

Only firms with a phone number on file are listed — without one the entry cannot be acted on. Sorted by postal area, alphabetically inside each: the IRS records a credential, not the quality of the work, and we have no basis to rank. Street addresses are deliberately not published; the ZIP is there so you can find someone on your side of town.
Which size fits you
The large national firms listed on this page audit public 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 two to five costs more and covers that, which is what you are paying the difference for.
The Washington market in numbers
| Establishments | 454 | 26,819 nationwide |
|---|---|---|
| Employees | 1,654 | 124,830 nationwide |
| Average annual pay | $39,871 | $25,031 nationwide |
| Employees per firm | 3.6 | 4.7 nationwide |
At 3.6 employees per establishment against 4.7 nationally, Washington is below the national average. In absolute terms that is a market of very small practices. That tells you who you will be dealing with rather than what you will pay: where practices are one- and two-person shops you talk to the person doing the work, and where they are bigger you are likelier to get an account manager and cover through filing season.
Storefront and seasonal preparers. Average pay in this code is low nationwide because much of the work is part-time and seasonal.

Questions
- How many tax preparers are there in Washington?
- 278 firms in Washington employ someone the IRS credentials to prepare returns — that includes CPAs, enrolled agents, attorneys and holders of the Annual Filing Season Program record.
- What is the difference between a CPA, an enrolled agent and an AFSP preparer?
- All three may prepare your return. A CPA, an enrolled agent and an attorney can also represent you before the IRS in an audit or appeal. An AFSP holder can only represent you on a return they prepared themselves. If representation matters to you, ask about the credential before you ask about the price.
- What do accountants earn in Washington, DC?
- Average annual pay in this category is $39,871 across Washington-Arlington-Alexandria, DC-VA-MD-WV Metro Area, against $25,031 nationally. Pay is a rough proxy for what a market charges: firms in expensive cities bill more because they pay more.
- How do I check that an accountant is actually licensed?
- The IRS publishes a directory of credentialed preparers, and every state board of accountancy runs a license lookup. The listings on this page come from the IRS record, which shows a credential — it does not say anything about the quality of the work, and this site does not rank firms.
