Accounting Services M&A Trends 2026

If I had to sum up 2026 in one line: more firms are selling or merging, buyers are pickier, and price now depends more on firm quality than market heat.

I see four clear points in this market:

• Deal activity stayed high, with 12,856 deals in 2025, up about 17% from 2024
• Competition for deals is up, with 8.5 buyers per deal in 2026 YTD versus 3.0 in 2022
• Multiples came down, as middle-market pricing moved from 9.8x EBITDA in 2025 to 7.4x in early 2026
• The best prices go to firms with steady revenue, low client concentration, solid margins, and less owner reliance

Put simply: if you’re buying, I’d focus less on headline price and more on structure, client retention, and staff staying in place. If you’re selling, I’d work on recurring revenue, management depth, and cleaner handoff before going to market. And if you’re investing, I’d pay close attention to firm size, because buyer type, financing, and valuation all change by revenue and EBITDA band.

Here’s the market at a glance:

The core takeaway is simple: predictable firms win. In 2026, buyers still pay up for firms that look steady, easy to hand over, and easier to keep after closing.

Deal volume in 2025 and 2026

Annual and year-to-date transaction trends

2025 was a record year for professional services deal flow, and accounting and tax advisory firms moved with that wave. Deal volume hit 12,856, up from an estimated 10,988 in 2024. That works out to roughly 17% year over year.

Early 2026 stayed busy, even with lenders tightening underwriting and interest rates holding high. One number shows the pressure clearly: in early 2026, 8.5 buyers were chasing each deal, up from 3.0 in 2022. That's a big jump, and it helps explain why well-run firms still drew heavy interest.

That leads to the next piece of the story: who exactly is buying these firms?

Why deal volume stayed high despite tighter buyer selectivity

Deal volume stayed high for a simple reason. Firms kept using M&A to grow, defend margins, and put more money into technology.

There was also a clear pricing signal in the market. Accounting firms with more than 60% recurring revenue command meaningful valuation premiums. Buyers may have become pickier, but they were still willing to lean in when the revenue base looked steady and predictable.

At the same time, pricing came down from the prior peak. Median middle-market EBITDA multiples fell to 7.4x in early 2026 from 9.8x in 2025. That shift helped keep deals moving even as financing got tougher. In plain English: buyers were more selective, but lower multiples gave them more room to act.

High volume, then, didn't mean every target had a line out the door. It meant the market was still active, even as buyers became far more selective. The next section breaks down who those buyers are.

The State of CPA Firm M&A: Private Equity, Timing & the Headline Offer Trap | Podcast Crossover

Buyer mix: Who is buying accounting firms in 2026

In 2026, who's buying matters just as much as how many deals get done. Private equity, strategic firms, searchers, and independent sponsors are all in the market. But they’re not chasing the same firms, and they’re not using the same deal playbook.

Private equity and sponsor-backed platforms

Private equity and sponsor-backed platforms are still active buyers. The reason is pretty simple: accounting firms tend to have sticky client relationships and recurring revenue. That’s exactly the kind of profile financial buyers like when they’re building a platform through add-on deals.

Most PE-backed groups start with a regional anchor firm. From there, they add smaller practices to expand into new geographies, bring in service lines like advisory or specialized tax, and improve margins by sharing back-office systems. In 2026, these buyers are leaning harder toward larger firms, where scale makes integration easier and gives them more room to improve margins.

Strategic buyers, searchers, and independent sponsors

Strategic buyers, including independent CPA firms and regional consolidators, are active across a broad range of deal sizes. In 2026, one shift stands out: defensive consolidation is showing up more often as smaller firms merge to split overhead and invest in AI tools so they can stay competitive. At the lower end of the market, these mergers of equals are playing a bigger role in shaping deal activity.

Searchers and independent sponsors are usually focused on smaller firms where succession is the main issue. They often use SBA 7(a) loans, seller notes, and earnouts to close valuation gaps. In 2026, cash-only deals are rare for firms under $20 million in revenue. Most deals in that range use 40% to 70% cash at close, with the rest paid through earnouts over two to four years.

That split in buyer strategy lines up closely with firm size, which is also a big driver of pricing in the next section.

Buyer mix by category: 2025 vs. 2026

The clearest change in 2026 is that defensive consolidation is more visible among strategic buyers. At the same time, searchers and micro-PE buyers still matter at the smaller end of the market. Buyer type, financing, and valuation now vary most by firm size, which the next section breaks down.

Firm size, specialization, and valuation in 2026

In 2026, firm size does most of the heavy lifting when it comes to who buys, how the deal gets structured, and what price range is even on the table. After that, specialization and day-to-day execution push a firm higher or lower inside that range.

Deal activity by revenue band

Buyer groups line up closely with firm size, and that size now shapes both structure and price. The market breaks into four clear bands.

Firms under $500,000 in revenue usually draw interest from individual CPAs or local competitors that want to fold in a client base. These deals live or die on client retention and a smooth owner handoff.

In the $500,000 to $2 million band, search funds and independent sponsors are the most active buyers. They tend to look hard at recurring advisory revenue and whether the staff is likely to stay put.

Mid-sized firms in the $2 million to $5 million range draw lower-mid-market PE groups and regional platforms. Here, buyers want less founder reliance. In plain English, they want a firm that can run for 90+ days without the founder, plus niche tax or audit know-how.

At the top end, firms between $5 million and $20 million are the main targets for mid-market PE and strategic consolidators. These buyers look for scalable processes, tech-enabled operations, EBITDA margins above 20%, and low client concentration.

What drives valuation in 2026

Inside each size band, specialization and operating discipline shape where a firm lands. In 2026, buyers are pricing firms on EBITDA, and multiples change a lot by size:

• Under $1 million EBITDA: 2x–4x (SDE basis)
• $1 million–$3 million EBITDA: 4x–6.5x
• $3 million–$5 million EBITDA: 5.5x–8x
• $5 million–$10 million EBITDA: 6.5x–10x
• $10 million–$25 million EBITDA: 7.5x–12x

Three things tend to move a firm toward the top or bottom of its range.

First is recurring advisory revenue. If a firm shifts even 20% of one-time transactional work into retainer-based advisory, its multiple can go up by more than half a turn.

Second is client concentration. When one client makes up more than 10%–15% of total revenue, most buyers will mark the deal down, and plenty will walk away.

Third is founder dependence. If the founder still owns most of the client ties personally, the firm is tougher to finance and tougher to sell at a better price. Sellers who step back 12 to 24 months before going to market, put processes in writing, and name operating leaders usually get stronger terms.

Firm profile comparison by revenue band

These valuation spreads shape what buyers can pay, what sellers can push for, and where investors may still see upside. They also set up the next set of practical decisions each group has to make.

What the 2026 data means for buyers, sellers, and investors

Those valuation bands now shape three big calls: what buyers can afford, when owners should sell, and where investors should put money.

What buyers and searchers should know

After a deal closes, the biggest risk is often simple: people and relationships. Culture can drift. Clients can leave. And that’s where deals can go sideways.

Successful acquisitions usually keep 75% to 95% of clients in the first 12 months. That’s why integration planning can’t wait until closing day. It should start during due diligence, with financial systems and project management tools lined up in the first 90 days.

For deals under $20 million, the structure often matters just as much as the headline price. These transactions usually mix:

• cash
• seller notes
• earnouts

A $10 million offer doesn’t mean much if the terms are rough. Smart buyers look past the sticker price and focus on how the deal is built.

Those same filters also shape which owners can ask for top-of-market pricing.

What sellers and family-office investors should know

Sellers with strong recurring revenue, diversified client bases, and EBITDA margins above 20% are in a better spot to earn premium valuations. Buyers pay more for firms that look steady, not shaky.

Smaller firms are also merging to protect margins and fund AI adoption. That wave of consolidation is shrinking the time owners have to sell into a competitive market on favorable terms.

For family offices and deal-by-deal investors, EBITDA size changes the field of buyers. Under $1 million, individual buyers and search funds are the most active. At $1 million to $3 million, lower middle-market PE and search funds show up more often. At $3 million to $5 million, PE funds, family offices, and strategics are active.

Core takeaways from accounting services M&A in 2026

In 2026, the highest prices go to firms that feel predictable: recurring revenue, diversified clients, low founder dependence, and clean integration planning.

FAQs

Why are buyers more selective in 2026?

Buyers are more selective in 2026. Accounting and tax advisory deals are being shaped by disciplined strategy, tighter credit, and changing tech expectations.

Valuations still vary a lot based on firm size and niche. But buyer attention is shifting toward firms with strong digital systems and AI capabilities. And with DSCR requirements sitting around 1.30x to 1.60x, deals often need more flexible structures, including earn-outs, seller notes, and equity rollovers.

What makes an accounting firm worth more?

In 2026, accounting and tax advisory firm values are being shaped by a more disciplined M&A market, steadier interest rates, and a growing number of founder-led firms coming up for sale as Baby Boomer owners head toward retirement.

On the buyer side, the focus is clear. Firms are putting more weight on operational fit, digital capabilities, and flexible deal terms like earnouts, seller notes, and equity rollovers. Those structures help close valuation gaps and give buyers a way to manage risk without walking away from the deal.

How does firm size affect deal structure?

Firm size has a big effect on both valuation and deal terms.

Smaller firms with $1 million–$3 million in EBITDA usually trade at 4x–6.5x. Once a firm gets above $10 million in EBITDA, valuations often move up to 7.5x–12x or more.

That gap matters. Bigger firms tend to draw stronger buyer demand, which can push multiples higher and give sellers more room in negotiations.

Deal structure shifts, too. Larger transactions can handle more layered setups, while buyers across the market are using earn-outs, seller notes, and equity rollovers more often to cut risk and close valuation gaps.
