CPA firm website design is the work of answering a client's seven questions, securely and fast, within the AICPA Code: who you serve, who you are and what you are licensed to do, how the engagement works, what it costs, what clients say, how to reach you and send documents safely, and why to trust you. The credential and security pages carry more weight here than in most industries.
This guide is part of our professional services series. The wider plan is in marketing for accounting firms; the legal counterpart in law firm website design; the running costs in website maintenance cost.
The seven things a client checks
In roughly the order they ask:
- Do you serve people like me? Services by client type: small businesses in named sectors, individuals with complex returns, nonprofits, startups; not a list of every service the firm could offer.
- Who are you, and are you licensed? Partner and staff pages with real photographs, the CPA license and state, other credentials, and what each person does.
- How does it work? What happens after the first call: the engagement letter, the document request, the portal, the timeline through the year.
- What does it cost? Fixed fees, hourly rates or how a quote is given, stated plainly even where the number cannot be, and never a fee the firm knows will rise.
- What do clients say? Testimonials within the Code and the FTC's disclosure rules, from clients who agreed.
- How do I reach you and send documents safely? A tappable number, a short form for first contact, a secure portal for everything sensitive, hours and the real address.
- Can I trust you with this? Licenses, memberships, a privacy and data-handling page, a current site that looks after itself.
The AICPA Code's rules for the copy
The AICPA Code of Professional Conduct's advertising rule (1.600.001) says a member in public practice shall not seek to obtain clients by advertising or other forms of solicitation in a manner that is false, misleading or deceptive, and that solicitation by coercion, over-reaching or harassing conduct is prohibited. Its interpretation (1.600.010, effective 15 December 2014) gives the tests: promotional efforts are false, misleading or deceptive if they create false or unjustified expectations of favorable results, imply the ability to influence any court, tribunal, regulatory agency or official, represent that services will be performed for a stated fee when it was likely the fee would be substantially increased without telling the prospective client, or contain any other representation likely to cause a reasonable person to misunderstand or be deceived. The Code also tells members to refer to state accountancy laws and board rules on use of the CPA credential.
For the website that means: no "we get you the biggest refund" or "we make IRS problems disappear"; no implication of influence with the IRS or a court; fee statements the firm can honour; testimonials that do not promise outcomes; and the CPA title used only by and for people who hold it. We are a web design and marketing company and never call ourselves CPAs; the partners review every page before it goes live. This is a summary, not professional or legal advice.
Why credentials carry the page
The IRS's guidance on choosing a tax professional (reviewed 21 August 2026) says anyone can be a paid tax return preparer as long as they have a PTIN, that preparers' skills, education and expertise vary, and that the IRS publishes a directory of preparers who hold recognized credentials. Circular 230 (reviewed 28 May 2026) sets mandatory rules of conduct for attorneys, CPAs and enrolled agents who practise before the IRS. A client who has read that guidance is looking for the license; a CPA firm's site should make the credential, the state of licensure and the firm's standing easy to find on every person's page and on the about page, in the words the state board allows.
The pages
A home page that says whom the firm serves and what to do next; a services page per client type rather than per technical service; a people page per partner and senior staff member with credentials; a how-we-work page; a fees page; a testimonials page; a secure portal link in the header and on every page; a contact page with the real address and hours; an about page with licenses and memberships; a privacy and data-handling page; and, where the firm publishes, a resources section on deadlines and rule changes, each piece carrying a not-advice line. The table below sets each page against the client question and the Code's test.
Security as design
Accounting clients send the most sensitive documents a business has. The site's design should route every sensitive exchange to a secure portal and keep the ordinary contact form for first contact only, with a visible note saying so; state plainly how client data is stored, who sees it and how long it is kept; and keep the site itself patched and backed up, as our guide to website maintenance cost guide describes. A firm whose site invites tax documents by email has told the client something about its care.
Phone first, fast and accessible
Pew Research puts US smartphone ownership at 91% of adults (19 October 2026), and a business owner checks a firm between meetings. The site must meet web.dev's Core Web Vitals targets, a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint within 200 milliseconds and a Cumulative Layout Shift within 0.1 at the 75th percentile of visits (updated 31 October 2024), with a tappable number and a portal link that works with a thumb. Plain language, readable type and labeled forms serve clients who are stressed about a deadline or reading in a second language.
The local search connection
Most accounting firms are found locally. Google's local ranking help says results rank on relevance, distance and prominence, that complete information and replies to reviews help, and that no position can be bought. An office page per location with the real address and hours, consistent name, address and phone, and service pages that match what clients search ("small business accountant [city]", "CPA for dentists") connect the site to the profile. Our local SEO service does the joining.
What a CPA firm website costs
The cost follows the pages and the review work. A small firm on a template with four service pages, three people and a portal link is a small-business site; a multi-office firm with many partners, sector pages, a resources section and integrations is a larger marketing site. The public bands are in our guides to how long it takes to build a website and WordPress website development cost. We publish no rate card; a firm's site is quoted against a written page plan.
Common CPA firm website mistakes
The faults we see most:
- A list of every service. Clients look for their kind of business, not for "attestation".
- Credentials hidden. The license and the state should be on every person's page.
- Promises. "Maximum refund" and "we resolve IRS problems" create the unjustified expectations the Code forbids.
- Sensitive documents by contact form or email. The portal link belongs in the header.
- No fees page. Even "fixed fees quoted after a first meeting" is an answer.
- A site nobody maintains. Out-of-date deadlines and an unpatched platform both say the firm is careless.
Conclusion
CPA firm website design earns trust by answering the client's seven questions plainly, within the AICPA Code's rule against false, misleading or deceptive advertising: services by client type, people with their licenses visible, how the engagement works, how fees are set, honest testimonials, a secure way to send documents and the signs of a careful firm. Make it fast on a phone, connect it to local search, and have the partners review every page.
