How to Buy a CPA Practice: A Buyer's Guide for 2026

The Opportunity

Every day, 10,000 baby boomers retire. A significant chunk of them are CPAs and EAs who spent 30+ years building tax practices they can't take with them.

For a buyer, that's a once-in-a-generation opportunity.

The math is simple: a well-run tax practice generates predictable, recurring revenue. Clients come back every year. There's no "churn problem" like in SaaS. A practice with 200 clients at $2,500 average fee is worth something real.

But buying a practice is also where dreams go to die if you get it wrong. Overpay. Miss the red flags. Inherit a mess you can't unwind.

Here's how to do it right.

Step 1: Know What You're Looking For

Not all practices are created equal. The first question isn't "how much?" — it's "does this fit?"

Good fit indicators:

• The client base matches your strengths. If you're a small business specialist, buying a real estate-heavy book doesn't make sense. You'll struggle to retain clients who expect expertise you don't have.
• The location works. Even in a remote-friendly world, most tax clients prefer local. If the practice is in California and you're in Florida, expect retention to drop 20-30% in year one.
• The mix is sustainable. A practice that's 90% tax prep with zero advisory is a treadmill. You'll work 70-hour seasons and never build equity beyond the client list. Look for practices with at least some bookkeeping or advisory revenue.
• The seller is willing to stay for a transition. Six months minimum. Twelve is better. The seller's relationship with their clients is the asset you're buying. If they walk out the door on closing day, those relationships walk with them.

Step 2: Valuation — What's It Worth?

The standard rule of thumb in 2026: 1x to 1.5x annual gross revenue.

A practice generating $400K in annual revenue typically sells for $400K–$600K.

But the multiple depends on quality:

Factor	Premium (1.3x+)	Discount (sub 1x)
Client retention rate	90%+ year over year	High churn, seasonal only
Revenue mix	Tax + bookkeeping + advisory	100% tax prep
Staff	Trained team stays	Sole practitioner, no staff
Systems	Documented processes, modern stack	Shoebox and a calculator
Location	Growing metro area	Declining rural area
Seller transition	12-month phase-out	Walk away at close

The trap: Don't pay for past revenue that won't follow you. A practice collecting $500K in fees is worth $500K only if 80%+ of those clients renew. Ask for the last three years of client lists and check the renewal rate.

Step 3: Due Diligence — The Questions That Matter

You're not buying a spreadsheet. You're buying relationships. Here's what to investigate:

Client concentration:

Ask for a ranked client list by revenue. If the top 5 clients represent more than 30% of revenue, you're buying risk — not a practice. One of those clients leaves, and your economics shift dramatically.

Fee structure:

Are clients on annual retainers, per-return pricing, or hourly? Retainers are gold. Per-return is fine. Hourly is a red flag — it means inconsistent revenue and unhappy clients who feel nickel-and-dimed.

Staff situation:

Will the staff stay? If the practice has a senior preparer who's been there 15 years, that person is the practice. Make sure they're part of the deal. Offer retention bonuses tied to staying 12 months post-acquisition.

Technology stack:

Are they still using a DOS-based tax program from 1999? You're going to spend six months and $20K migrating. Factor that into the price.

Pending issues:

Any IRS clients under audit? Any unhappy clients who might sue? Any ethical skeletons? Ask directly.

Step 4: Structuring the Deal

Most practice sales use an earn-out structure — you pay part upfront and part over 2-3 years based on client retention.

A typical deal:

• 30% upfront (cash or SBA loan)
• 40% over 12 months (monthly payments tied to collections from the acquired book)
• 30% over 24 months (bonus if retention hits targets)

This protects both sides. The seller gets a fair price. You don't overpay for revenue that doesn't stick.

SBA loans are available for practice acquisitions through most banks. You'll need 10-20% down, good credit, and a solid business plan. The SBA 7(a) program is the most common route.

The Bottom Line

A practice acquisition is the fastest way to go from zero to a thriving firm — but only if you buy the right practice at the right price with the right transition plan.

The window for buying is wide open. Retiring boomers are listing every week. But the deals that work aren't the ones with the highest revenue or the lowest price. They're the ones where the buyer did the homework.
