Accountant email signature software for CPA firms and bookkeepers
In an accounting firm the signature is regulated text. "CPA" after a name is a licensed title, and the staff accountant who passed the exam in July is not allowed to use it yet. AutoSignature fills the designation from your directory so only licensed people carry it, and puts one approved confidentiality notice and a secure portal line on every email, in Outlook and Gmail.
Flat price per firm from $49 a month billed yearly, not per preparer. Try the signature console on this page without an account.

The short answer
Accountant email signature software sets one approved signature for everyone at a CPA or bookkeeping firm, instead of letting each partner, senior and preparer keep their own. It fills names and titles from your directory, adds "CPA" only for people you mark as licensed, locks the firm name, a secure portal line and one confidentiality notice, and writes the result into each mailbox. State law reserves the CPA title for licensees in every state we checked, and California requires the word "inactive" on correspondence for inactive licensees. AutoSignature covers Microsoft 365 and Google Workspace on every plan, from $49 a month per firm billed yearly.

Can you put CPA in your email signature before you are licensed
No. Passing the exam is not the license, and the title belongs to the license. New York's Education Law 7402 says only a licensed person may "use the title 'certified public accountant' or the designation CPA." Texas Occupations Code 901.451 and Florida Statutes 473.322 say the same, and the model Uniform Accountancy Act bars any title "tending to indicate" CPA status without a valid certificate.
No rule we read names the exam passer waiting on a license, but those general bans cover the case. So the safe signature for a candidate is name and job title, for example "Senior Staff Accountant", until the license is issued.
Watch the near misses too. California's board lists "accountant" and "auditor" among titles likely to be confused with CPA, and New York makes "tax accountant" a misdemeanor for unlicensed people. Have whoever owns licensing confirm the wording before you lock a template. This page is general information, not legal advice.

CPA title and signature rules by state
The rules that decide what belongs in an accountant's signature, read from the statute, regulation or model act text. Each row can become a group template in AutoSignature, so an inactive licensee in California or a retired partner in Florida carries the right wording without anyone typing it.
| State | Rule | Who may use CPA | Inactive or retired wording | What it means for the signature |
|---|---|---|---|---|
| California | B&P 5055, 5058, 5058.2, 5058.3; 16 CCR 2 | Certificate holders and registered firms only; "accountant" and "auditor" listed as confusable titles | "Inactive" or "retired" immediately after CPA on correspondence, websites and business cards | The one rule that names correspondence directly. An inactive licensee's email signature must say so. |
| California | 16 CCR 50 | Licensees serving clients | Not applicable | Clients must be told the licensee is licensed by the California Board of Accountancy; a letterhead statement or an electronically transmitted notice are allowed methods |
| Texas | Occ. Code 901.451, 901.453, 901.455; 22 TAC 501.81 | Certificate holders only; "accountant" or "auditor" holding out requires a license | None found in the CPA title rules | "And Company" or "and Associates" in a firm name needs at least two licensees in the practice |
| New York | Educ. Law 7402, 7408 | Licensees only; "tax accountant" and "certified tax accountant" are misdemeanors for others | None found | "Enrolled agent" or "E.A." is reserved for people the IRS has enrolled |
| Florida | F.S. 473.322, 473.313 | Active licensees only; an inactive or delinquent license may not be used | "Retired CPA" allowed on any printed or electronic document | Retired partners who still email clients can keep a correct "retired CPA" line |
| North Carolina | 21 NCAC 08N .0306 | Registered firms on letterhead | Not addressed | CPAs offering services via the internet show the firm name, a phone number and their NC certificate number |
| Model act | UAA Section 14(c), 6(d) | Valid certificate holders only | "Inactive" adjacent to the CPA title on business cards, letterhead and other documents; "retired" from age 55 | Most states build their rules from this text, so treat it as the default |
Read in October 2026 from the Texas Legislature's statute files, the New York State Education Department, the Florida Statutes, the North Carolina Administrative Code, NASBA's Uniform Accountancy Act, and the California and Texas rules as carried by public.law and Cornell's Legal Information Institute. None of the CPA title rules uses the word email, but California's inactive rule names correspondence. Texas has proposed changes to its board rules in 2026, so check the current text if you practice there.
Do accountants still need a Circular 230 disclaimer in email
No. The disclaimer existed because of the covered opinion rules in the old section 10.35 of Circular 230, and Treasury removed them in T.D. 9668, effective June 12, 2014. Its preamble says Treasury and the IRS expect the change "will eliminate the use of a Circular 230 disclaimer in email and other writings." A short statement of the real limits of your advice is still allowed.
Drop
The Circular 230 paragraph
The long "any tax advice contained in this communication is not intended or written to be used" block. It answers a rule that no longer exists and makes every reply four lines longer.
Keep
A secure portal line
The FTC Safeguards Rule treats tax preparers as financial institutions and requires customer information to be encrypted in transit. IRS Publication 4557 says to send only encrypted or password protected files by email. A signature line pointing clients to the portal backs that up on every message.
Optional
A short confidentiality notice
No rule we found requires one. Firms keep a single sentence because it tells a misdirected recipient what to do. What matters is that it is one approved wording, not a paragraph each person wrote.
Enrolled agents have their own wording rule. Circular 230 section 10.30 says they "may not utilize the term 'certified'" when describing the designation, and offers "enrolled to represent taxpayers before the Internal Revenue Service" as an approved description. A separate template for the EA group keeps that line exact. Firms that collect client bank statements through the portal often pair it with a tool to convert PDF bank statements to Excel, so the numbers are never retyped.
Where accounting firm email signatures go wrong
Nobody at a firm puts a wrong title in a signature on purpose. It happens because forty people, plus nine seasonal preparers, each keep their own.
CPA added too early
A senior passes the last section in August and adds "CPA" the same week. The license is issued in November. For three months every email to a client uses a title the state board reserves for licensees.
The copied partner signature
A new associate copies a manager's signature to save time, credentials and all. Now an unlicensed person's email ends with "CPA" and someone else's license state.
A disclaimer from 2013
Half the firm still carries the old IRS Circular 230 paragraph, the other half dropped it, and two people wrote their own. Clients see three versions of the firm's legal voice.
Seasonal preparers
Preparers start in January with whatever signature their laptop came with. By the time anyone notices, it is March 20 and nobody has time to fix nine mailboxes.
What should an accountant's email signature include
An accountant's email signature should include the full name with "CPA" only if the person holds an active license, the job title, the firm name, a direct phone number, the office address and website, a line telling clients to send tax documents through the secure portal, and one short confidentiality notice approved by the firm. Here is where each line comes from in AutoSignature.
| Line | Example | Where it comes from |
|---|---|---|
| Name and designation | Rachel Hollis, CPA | Directory name plus a managed credential field that only licensed staff have filled |
| Title | Managing Partner, or Senior Staff Accountant | Directory job title, kept current by HR |
| License state | Licensed in Illinois | Optional field, useful for multi-state practices and remote staff |
| Firm name and phone | Hollis & Park CPAs, +1 312 555 0147 | Locked in the template, identical on every mailbox |
| Office and website | Chicago office, hollispark.example | Office field, so a move or a second office updates every signature at once |
| Secure portal line | Never email Social Security numbers or bank details. Use our client portal. | Locked block, on for every client facing group |
| Confidentiality notice | This message is confidential and intended for the addressee only. | One approved wording, locked, set on the email signature disclaimer software page |
| Season banner | Book your year end tax planning meeting | Scheduled for partners only, November 1 to December 15, on the email signature banners feature |

Rolling it out across an accounting firm
Most firms are live in an afternoon, outside tax season or in it. Nothing is installed on a laptop or a phone, and nobody has to open a settings screen.
01
Connect the mail domain
Sign in to Microsoft 365 or Google Workspace as an administrator. Names, titles, offices and phone numbers come from the directory you already keep.
02
Mark who is licensed
Fill the credential field for licensed CPAs and enrolled agents, once, from your license tracking sheet. Everyone else's field stays empty, so their signature shows no designation.
03
One template per group
Partners, tax, audit and assurance, advisory, administration, seasonal preparers. Same logo and layout, different lines and banners underneath.
04
Apply and keep it applied
Signatures are written into each mailbox. A newly licensed CPA gets the designation the day you fill the field, preparers are cleared on April 16, and every change has one step rollback.
Step by step on centralized email signature management. Firms on Outlook should read Office 365 email signature management, and those on Gmail Google Workspace email signature management.
Who buys this
10 to 150 staff
Regional CPA firms
Big enough that the managing partner cannot read every senior's email, small enough that IT is an outside provider and the firm administrator owns the signature.
January to April
Tax practices with seasonal preparers
A preparer group that is signed on day one and cleared on April 16, on a flat bill that does not climb for four months.
Licensed and not
Firms with CPA candidates on staff
Exam passers, staff accountants and enrolled agents side by side, each with the designation they are entitled to and nothing more.
Client accounting
Bookkeeping and outsourced accounting firms
Bookkeepers write to clients every day about bank feeds and missing receipts. One signature with the portal line stops statements arriving as email attachments.
After a merger
Firms that combine or rebrand
A new firm name on a set date across two mail systems. Switching every mailbox in one rollout is the easiest part of the merger to get right.
A note on fit
Solo practitioners
A one person practice can set its own signature by hand. This page is written for firms where more than a handful of people email clients.

CodeTwo is cheaper than us at 25 and 100 if every mailbox is on Microsoft 365, and Exclaimer is cheaper at 25 and 100. We come out ahead at 150, when the firm runs both Outlook and Gmail, or when the preparer headcount swings each spring.

Accountant email signature questions
Should I put CPA in my email signature?
Yes, if you hold an active CPA license. Licensed CPAs normally put the designation right after their name, and many add the state that licensed them. If your license is inactive, California requires the word inactive immediately after CPA on correspondence, and the model Uniform Accountancy Act asks for the same on any document. Staff without a license leave it off.
Can I put CPA in my email signature before I am licensed?
No. Passing the CPA exam does not license you, and state law reserves the CPA title for license holders. New York, Texas and Florida all say so in their statutes, and the model act bans any title tending to indicate CPA status. Use your job title, such as Senior Staff Accountant, until the license is issued.
What should an accountant's email signature include?
An accountant's email signature should include the full name, CPA or EA only if the person holds that credential, the job title, the firm name, a direct phone number, the office and website, a line asking clients to send tax documents through the secure portal, and one short confidentiality notice approved by the firm.
Is the Circular 230 disclaimer still required in emails?
No. The Circular 230 email disclaimer came from the covered opinion rules in former section 10.35, which Treasury removed in T.D. 9668, effective June 12, 2014. The IRS said it expected the change to end the use of the disclaimer in email. Firms may still state the real limits of a piece of advice.
How do you write CPA inactive in an email signature?
Put the word inactive immediately after the designation, for example Jane Doe, CPA (inactive). California Business and Professions Code 5058.2 requires this on correspondence, websites and business cards, and the model Uniform Accountancy Act asks for inactive adjacent to the CPA title. Retired licensees in Florida may use retired CPA instead.
Can an enrolled agent use certified in an email signature?
No. Circular 230 section 10.30 says enrolled agents may not use the term certified or imply an employment relationship with the IRS when describing their designation. Approved wording includes enrolled to represent taxpayers before the Internal Revenue Service. New York also reserves enrolled agent and E.A. for people the IRS has enrolled.
Can an accounting firm manage every employee's email signature from one place?
Yes, when the firm owns its mail domain on Microsoft 365 or Google Workspace. AutoSignature writes the approved signature into every mailbox, fills the CPA designation only for staff you mark as licensed, and changes every signature at once when someone is licensed, a partner retires or the firm merges.
The right designation on every client email
Team is $99 a month for up to 25 mailboxes, Business is $299 a month for up to 150, and yearly billing takes 50 percent off. Every plan covers Microsoft 365 and Google Workspace, and the bill does not move when preparers join in January.
