After a Merger: Your Old Firm Name, Domain and Profile

When a local accounting firm is acquired, its old name, old domain and old Google Business Profile keep describing it as an independent firm until each one is deliberately changed. AI answers draw on those same public sources, so a merger can leave an answer naming a firm that no longer exists, at a phone number that now rings somewhere else. Each of the three has a documented path, and the order matters.

The three places the old firm lives on

Picture a hypothetical two partner practice, Delgado Tax & Accounting in Fresno, acquired by a regional group that will operate it as the group's Fresno office. The day the deal closes, the web still holds:

The name, on the old sign, the old letterhead, directory listings and years of local news mentions.
The domain, delgadotax.example, with its service pages, staff bios and the reviews clients linked to.
The Business Profile, with hours, phone, category and every review the firm earned.

None of these update themselves, and the parent brand's site does not overwrite them.

Is the new name allowed at all?

Start with the professional rules, because they decide what the other steps may say. The AICPA Code, at 1.800.001, says a member "shall not practice public accounting under a firm name that is misleading," and that past owners' names "may be included in the firm name of a successor organization." Interpretation 1.820.030 adds that state rules on firm names may be more restrictive. Section 14(i) of the Uniform Accountancy Act allows former partners' names and a common brand for network firms. If the Fresno office will call itself a CPA firm, the state permit has to match the name used.

The Business Profile: rebrand or close and replace

Google's Business Profile guidelines draw a firm line. A rebrand on the existing profile is possible for "a minor name change, in which the proper nouns and services described in the business name remain unchanged and the business category remains unchanged," and for multi-location businesses whose name changes. Otherwise the change "is considered a new business. You must mark the existing Business Profile as closed and then create a new Business Profile." The guidelines also say the name "should reflect your business's real-world name, as used consistently on your storefront, website, stationery."

So "Delgado Tax & Accounting" becoming "Delgado Tax & Accounting, a Sierra Group firm" may qualify as a rebrand; becoming "Sierra Group Fresno" likely does not. Change the sign and the website first, then the profile, so the real-world name the guidelines ask for already exists. Microsoft points owners to Bing Places for Business to claim or update the listing that appears in Bing Maps, and that listing needs the same change.

The domain: redirect, page to page

Google's site move guidance recommends permanent server side redirects "such as 301 and 308" from old URLs to new ones, "avoiding chained redirects," and says to keep them "for as long as possible, generally at least 1 year." Send each old page to its closest equivalent: the tax page to the Fresno office's tax page, each bio to the same person's new bio. Sending everything to the parent's homepage throws away the specific context an old page carried.

A merger sequence for the acquired office

Before close: confirm the new name with the state board and the AICPA naming rules; list every URL on the old site.
Close week: publish the office page on the new site with the full name, address, phone, people and a sentence about the history: "Formerly Delgado Tax & Accounting, founded in 2004."
Same week: switch on the redirects; update the Business Profile by rebrand or close and replace.
First month: update Bing Places, Yelp, QuickBooks or Xero advisor listings, and association directories.
First year: keep the old domain registered and redirecting.

That "formerly" sentence is worth keeping for good: it is the one line that lets a reader, or a model, connect years of references to the old name with the office that exists now. Our guide to details that disagree explains why stale listings hurt. For the private equity version of this problem, see which entity is the CPA firm after a deal, and the overview lives at AI visibility for accounting firms.

Not legal or tax advice. This describes how AI systems read an accounting practice in public; your state board of accountancy, Circular 230 and your own counsel govern what you may publish.

Questions

Should an acquired accounting firm rename its Google Business Profile or create a new one?

It depends on how big the name change is. Google's Business Profile guidelines allow a rebrand on the existing profile when the proper nouns and services in the name stay the same and the category is unchanged. If the acquired accounting firm takes a different name, Google treats it as a new business: the old profile is marked closed and a new profile is created.

How long should an acquired firm's old website redirect to the new one?

Google's site move guidance recommends permanent server side redirects, 301 or 308, from each old URL to its closest new URL, kept for as long as possible and generally at least one year. For an acquired accounting firm, that means the old domain stays registered and redirecting, page by page, well after the merger announcement.
