How much can I sell my CPA business for in Illinois?
Client retention and who does the work set CPA-firm prices. A tax-season sprint that is only you is a wind-down with a phone number.

A licensed-broker view of value — not a listing-site guess
Accounting firms in Illinois are often discussed as a multiple of revenue — our planning range is 1x–1.5x annual revenue — with a 6–15 month process. That language exists because a recurring 1040 and write-up book can transfer when clients will take the successor’s call. It is still a recast: unpaid family payroll, the owner’s personal tax work, and one-time consulting projects need to come out.
A platform that buys advisory-heavy firms and a local CPA who wants your 1040 list are not the same process. Marketing both with one teaser wastes a tax season. Pick the buyer mix before you pick a list price.
BizBuySell’s 0.7× revenue multiple is a cross-industry figure and will usually understate a clean Illinois book. Do not use it as your asking price. Do use it as a reminder that revenue multiples without retention are slides, not closings.
Industry planning notes on this site: 1x–1.5x Annual Revenue, typical process 6–15 months. Those are planning ranges from our Accounting Firms hub, not a quote.
Enter your annual Seller's Discretionary Earnings (SDE) — your net profit plus owner's salary and any personal expenses run through the business — to estimate a range.
This is an estimate for planning purposes only. Actual value depends on lease terms, asset quality, customer concentration, and current market conditions. Request a professional valuation for a precise number.
Who buys Illinois CPA firms
SBA and owner-operator lenders
SBA can finance firm acquisitions when cash flow is real and the buyer is a licensed CPA (or has one in the deal). Lenders will ask about client concentration, realization rates, and whether the book is 80% individual 1040s that can walk to TurboTax. They will not treat ‘we’ve always gotten the referrals’ as a contract.
Private equity and platforms
Accounting platforms and regional aggregators buy when there is a team, some advisory or CAS revenue, and a managing partner who is not the entire production. Their LOI will include a retention holdback. That holdback is the price. Read it.
Owner-operators next door
Another Illinois CPA or a small partnership still closes many books. They want the clients, the staff, and a transition through one tax season. They will walk if the seller refuses a reasonable handoff or if the AMS is a shoebox.
Audit-heavy, tax-heavy, and CAS/advisory firms are different products. Peer-review status and independence rules change who can buy. Say which firm you actually run.
CPA-firm value is clients who will stay
Retention history, realization, and owner production versus staff production set the multiple. Software is supporting. A new conference table is not a multiple.
- Client retention over several seasons and concentration in the top ten clients
- Tax versus write-up versus advisory or CAS mix
- Owner production hours versus staff who can keep the book
- Billing rates, realization, and work-in-process that is actually collectible
- Office lease assignment and whether clients will follow a new address
Hypothetical: $800,000 revenue at 1.25x is $1.0 million. A 20% retention holdback means $200,000 is not cash at close. Model the holdback and the Illinois tax on the allocation before you spend the headline.
Illinois CPA sales: license, peer review, entity
The buyer needs a licensed CPA path and, if you do attest work, a peer-review and independence story. Client files and confidentiality are not a Mailchimp announcement. Notice timing belongs with counsel and the engagement letters you already signed.
Asset versus stock sale changes how the firm name, the PLLC or PC, and the Secretary of State filings move. Office leases still need landlord consent. Bulk Sales is less often the headline than in a parts business, but WIP, prepaid retainers, and equipment still need a clean schedule. We coordinate; your counsel and CPA (yes, you still need one who is not you) should review tax.
Realization rates tell the truth about billing. A firm that bills $400 and collects $260 is not a $400 firm. Bring realization and WIP aging. Platforms will. Local CPA buyers will too if they have bought before.
Attest work and peer review change who can legally buy you. Disclose early. Hiding a small audit shop inside a tax teaser is how a spring exclusive becomes a summer apology. Independence rules are not a listing-site FAQ.
Client notice is a planned season, not a Friday email. The book is the asset. A letter that starts shopping in February is how you fund someone else’s growth. We write the notice plan with counsel after a successor exists — not as a marketing stunt.
A 1040-heavy book and a CAS/advisory book are different firms at the same revenue. Platforms pay for the second. Local CPAs buy the first. Marketing both with one paragraph wastes a tax season. Split the teaser or split the process.
Office leases in professional buildings still need landlord consent. Clients will follow a new address more easily than a surprise letter. Sequence notice after a successor exists. The holdback is how the buyer says they do not believe you will.
Educational only — not legal or tax advice. Confirm Bulk Sales, Secretary of State filings, license transfers, and lease assignment with counsel and a CPA. We work on a success fee with no upfront listing fee.
Illinois CPA buyers underwrite clients who will file with someone else
A CPA-firm buyer in Illinois is buying a client list that will still sign engagement letters after the managing CPA’s name leaves the signature block. Tax-season intensity underwrites differently than year-round advisory. A book that is three October-extension families and one construction client is concentration, not a firm. SBA lenders will ask about realization rates, write-offs, and who actually does the work. Other firms buy books they can absorb onto their own license and peer review.
Platforms and regional firms appear when staff, not just the owner, already touch the files. Solo practitioners sell, but they sell a transition plan. Clients who will only talk to the seller support an earnout. Recurring write-up and advisory support a cleaner conversation. A teaser that treats every 1040 as permanent will be sampled. Let buyers sample the part you are proud of.
We recast SDE, run a revenue view, and will not invent a house accounting multiple on this page. BizBuySell’s Q2 2026 2.7× cash-flow and 0.7× revenue averages are market-wide context. If a roll-up letter arrived, read /private-equity-offer/accounting before you go exclusive. Recast at /contact.
IDFPR firm license, client notice, lease, Bulk Sales, and SOS
The IDFPR public-accounting page is the public door to licensed CPAs, registered CPAs, and firm licenses, including the designated managing CPA. The buyer needs a firm license and a managing CPA the Department will accept. Peer review and professional-liability continuity are diligence, not stationery. Client files move under engagement and confidentiality rules — counsel and your ethics file, not a listing site.
Office furniture and a going-concern transfer can trigger CBS-1 at least ten business days before closing. The office lease needs assignment if clients and staff know that address. A January move in the middle of tax season is a retention event, not a logistics footnote.
If the buyer wants the exact firm entity, the Secretary of State path and a membership or stock sale may preserve the name on engagement letters — or preserve problems. Structure is a counsel decision. Educational only. We work on a success fee with no upfront listing fee and we keep the sale out of the February waiting room.
Recast firm earnings as fees that survive a new signer
Build a client schedule by fee, service line, tenure, and concentration. Tax versus write-up versus advisory should not share one blended story. Owner hours that a hired manager or partner must replace are a wage. One-time 1031 or estate projects are not core SDE. Realization and write-off history tell you whether the billing rate is real. Buyers will test workpapers, not just the P&L.
Busy-season staffing that is the owner plus two tired preparers is a transition risk. Software lock-in is a cost. Do not add “the value of the book” on top of a cash-flow multiple as if it were a second asset. The book is the earnings. Personal returns of the seller’s family that will leave should be tagged before diligence does it with a smile.
We will not invent a house multiple. A planning conversation uses both BizBuySell views and then talks retention. Your own CPA — or a conflict-free colleague — owns tax on the sale and Form 8594. Irony is not a filing strategy. The IRS selling-a-business page is still the federal starting point.
What an accounting-firm model should not invent
A model should not invent a revenue multiple, a house quote, or a claim that every 1040 stays. It should not treat the $349,250 median sale as a firm price. It should not assume peer review and the managing-CPA designation move with the logo. Read /how-long-to-sell/accounting for the sequence — tax-season timing is a real clock.
Use /industries/accounting-firms for industry notes on this site. Use /net-proceeds-illinois before you spend a rule-of-thumb. If retirement is the motive, start before you are tired of extensions. See /should-i-sell-my-business-and-retire. The Exit Planning Institute found only 5 percent of Boomer respondents had a dedicated exit team. Do not be the firm that preaches planning and skips it.
Bring engagement summaries, realization reports, the firm license, and three years of returns to the consult. No upload portal. No upfront listing fee. Educational, not legal, ethics, or tax advice. The CTA is /contact.

CPA sale questions
Firms are often talked about as a revenue multiple (planning range 1x–1.5x). We still recast SDE so you can compare. Do not mix the two in one asking price.
Unlikely as a platform deal. Solo books usually sell to another CPA. Platforms want a team and some advisory mix.
On a written plan, usually after an LOI and a successor is identified. Premature letters start shopping.
Plan 6–15 months. A transition through a tax season is normal. A 30-day close is a story.
It narrows the buyer pool and adds diligence. Disclose it early. Hiding it is how LOIs die.
No upfront listing fee. Success fee at close. Schedule /contact.
No. We recast SDE, run a revenue view, and will not invent a house accounting multiple. BizBuySell’s 2.7× and 0.7× figures are market-wide. Client concentration and who signs the returns move risk more than a rule of thumb. Start at /contact.
IDFPR firm licenses and the designated managing CPA sit on people and registered firms. The buyer needs an acceptable license path before clients see a new signature block. We map the sale. Counsel and IDFPR handle the credential. Do not announce in the lobby first.
Usually not in the middle of it. Use /how-long-to-sell/accounting for the sequence. Client notice and lease timing matter more than a portal average, and February is a terrible surprise. We work on a success fee — /business-broker-fees — with no upfront listing fee.
