How Illinois Accounting Firms Sell
Owner playbook for Illinois accounting firms: licenses, how buyers recast the books, and a confidential planning range. No upfront listing fee.
Confidential • No upfront fees • Illinois statewide
Buyers price an Illinois accounting firm on adjusted seller’s discretionary earnings after they normalize the books — not on a rumor multiple. IDFPR CPA licenses are personal and do not transfer. Planning range: 1x–1.5x Annual Revenue.
How accounting firms actually sell in this state
IDFPR accountancy rules decide who can own and sign. Downstate 1040 shops have thinner buyer pools than Loop or North Shore advisory firms. Tax-season labor and software conversion are the operational risk. A stock sale that leaves the named CPA is a different file than an asset sale to a non-CPA consolidator.
Illustration: a two-partner CPA shop in Peoria with a heavy 1040 season, a growing monthly CAS book, and a selling partner who still reviews every business return. Not a closed sale.
Planning range on this site: 1x–1.5x Annual Revenue. Typical process when books, the lease, and licenses are ready: 6–15 months. Those are ranges from our industry notes, not a quote for your shop. Typical first calls: cpa firms, regional accounting groups, pe-backed platforms. SBA 7(a) is commonly available for qualified buyers, which expands the owner-operator pool. The current statutory maximum is $5 million. See the SBA 7(a) program page. Marketplace-wide, BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across all reported closed deals — context, not a accounting firm appraisal.
Recast a accounting firm the way a lender will
Buyers often talk 1x–1.5x revenue on small CPA books; this business uses 2.5x–4x SDE as the planning band next to other Main Street shops. Recast after a market-rate CPA if the seller still signs every return. Pull one-time catch-up books and any litigation-support year. Realization and write-offs tell the truth. A book that is 90 percent personal 1040s in March is not a 4x advisory firm.
Levers that move the multiple on this vertical: Recurring CAS or business-tax retainers; A staying CPA who can sign; Realization that survives a rate conversation; Low 1040-only concentration; Clean IDFPR and peer-review status. Flip those and you have the diligence fight.
IDFPR licenses people. Appointments and attest sit on the firm.
Insurance producer and CPA licenses are personal. Carrier appointments and “CPA” / attest use are firm-level and must be re-papered. A buyer without appointments or a signing CPA cannot legally do the work they just bought.
Advisory books add SEC or state IARD registrations. Households follow people. Retention is the diligence.
File Illinois Form CBS-1 at least ten business days before an asset transfer that meets the statute. Chicago and Cook County add 45-day local bulk-sale clocks when they apply.
Who writes a check for an Illinois accounting firm
CPA firms, regional accounting groups, PE-backed platforms show up first. City pages on this site (Chicago, Naperville, Joliet, and the rest) explain how that mix changes by county. A platform and an owner-operator do not underwrite the same file.
Buyers pay for transferable cash flow and a business that is not only the seller. They will argue client retention history, revenue per client, tax vs advisory mix, billing rates, client concentration. A public asking price on a recognizable storefront is a choice, not a default.
What a serious accounting firm buyer will open
Have these ready before anyone hears the name of the accounting firm:
- Fee mix: 1040, business tax, monthly CAS, attest
- Realization, write-offs, and aged WIP
- Who signs, who is staying, and IDFPR firm status
- Client concentration and whether the seller is the relationship
- Software (QBO, UltraTax, CCH) ownership and data export
- Peer-review status if they do attest
Where accounting firms lose a letter of intent
The usual walk items are owner dependency, a license that leaves, books that do not match the tax return, or a lease the landlord will not assign. On this vertical the specific fights are: recurring cas or business-tax retainers; a staying cpa who can sign; realization that survives a rate conversation; low 1040-only concentration; clean idfpr and peer-review status.
Start carrier appointments or peer-review / firm registrations at letter of intent. Illinois Form CBS-1 is due at least ten business days before an asset transfer that meets the statute.
What to gather before anyone hears the name
Three years of signed business tax returns and matching P&Ls. Year-to-date numbers and three months of bank statements that reconcile. The current lease, amendments, and remaining term. A license and permit list that names who holds each card. Top-customer concentration with names redacted until an NDA.
Then recast. Buyers often talk 1x–1.5x revenue on small CPA books; this business uses 2.5x–4x SDE as the planning band next to other Main Street shops. Recast after a market-rate CPA if the seller still signs every return. Pull one-time catch-up books and any litigation-support year. Realization and write-offs tell the truth. A book that is 90 percent personal 1040s in March is not a 4x advisory firm.
How buyers read the books on a accounting firm
Buyers often talk 1x–1.5x revenue on small CPA books; this business uses 2.5x–4x SDE as the planning band next to other Main Street shops. Recast after a market-rate CPA if the seller still signs every return. Pull one-time catch-up books and any litigation-support year. Realization and write-offs tell the truth.

Illustration only — not a quote for any Illinois shop. A accounting firm whose tax return shows $187,000 of net profit is not worth $187,000 × a rumor multiple.
Add back the owner’s $77,000 W-2 and payroll tax, $23,000 of discretionary benefits, $6,000 of accepted one-time cost, and $5,000 of personal expenses that a buyer will not run. Then subtract $73,000 of replacement labor if the owner still diagnoses, sells, or closes the books.
Adjusted seller’s discretionary earnings are $225,000. At the planning range 2.5x–4.0x, enterprise value is $562,500 to $900,000. Mid-range 3.25x is $731,250 before debt, working capital, holdback, and tax. A Illinois buyer will argue the multiple after they ride with the staff and read the lease.
Which licenses stay with the owner
IDFPR CPA licenses are personal and do not transfer. Firm names and “CPA” use are regulated. Peer review, if they do attest work, sits on the firm and the named partners. A non-CPA buyer cannot simply own attest work under Illinois accountancy rules. Client businesses transfer only with engagement-letter and confidentiality discipline.

How to prepare an Illinois accounting firm for sale
- Recast the tax return. Start with signed returns. Add owner pay and one-time costs. Subtract replacement labor if the seller still does the work a buyer must hire for on this accounting firm.
- Name the license holder. List every credential that lets the company operate and whether that person stays. Personal licenses do not transfer with the assets.
- Open the lease and the labor file. Remaining term, assignment rules, and whether the crew can run Monday without the seller.
- Calendar Illinois notices. File CBS-1 at least ten business days before a qualifying asset transfer. Add Chicago or Cook 45-day clocks when they apply.
- Talk before you list the name. Confidential outreach first. Employees and landlords recognize storefronts. A success-fee consult is how we start — no upfront listing retainer.

Questions owners ask about accounting firms in Illinois
Our planning range is 1x–1.5x Annual Revenue. BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across reported closed deals in all industries — useful context, not a accounting firm appraisal. The multiple moves on client retention history, revenue per client, tax vs advisory mix, billing rates, client concentration.
Plan on 6–15 months when books, the lease, and licenses are ready. License transfers and landlord consent are what push files past that range.
IDFPR CPA licenses are personal and do not transfer. Firm names and “CPA” use are regulated. Peer review, if they do attest work, sits on the firm and the named partners. A non-CPA buyer cannot simply own attest work under Illinois accountancy rules. Client businesses transfer only with engagement-letter and confidentiality discipline.
CPA firms, regional accounting groups, PE-backed platforms. City pages on this site explain how that mix changes by county.
Illinois accounting firms typically sell for 1x–1.5x annual revenue. Firms with high client retention, strong revenue per client, and a healthy mix of tax, bookkeeping, and advisory services command the higher end.
Client retention is the top priority in every accounting firm sale. We structure transitions with appropriate introductions, joint client meetings, and earnout provisions that incentivize the seller to support client retention during the handover.
All buyers sign an NDA before receiving any identifying information. Your clients will not know you are considering a sale until you choose to disclose it, typically after a deal is signed.
Yes. Sole proprietor accounting practices sell regularly. The key is demonstrating that clients are loyal to the firm and the work can be transitioned to a qualified buyer.
Buyers purchasing accounting firms in Illinois typically need to be CPAs. Some transactions involve non-CPA buyers who partner with licensed CPAs to manage the practice. We vet buyer credentials as part of our qualification process.
