Selling a Multi-State Tax Advisory Practice

Say, purely as an illustration, a firm does $2.1M a year, split between compliance filings for corporate clients across a dozen states and a smaller advisory practice on nexus and multi-state apportionment questions; in this example, roughly 60% of collections land between January and April, and the two founding partners want to sell within two years as they approach retirement.

The firm employs four full-time staff year-round and brings on six seasonal preparers each January. Client relationships average over eight years of tenure, a real strength the partners haven't thought to document formally anywhere a buyer could easily see it.

A buyer evaluating the firm on Acquire.com initially assumes revenue is flat month to month, the way SaaS ARR usually behaves, and has to be walked through the tax-season concentration explicitly. Once that's clear, the conversation shifts to a more realistic question: what does cash flow look like in the off-season, and does the firm need a line of credit to cover payroll between busy seasons. Presenting a monthly cash flow chart alongside the annual revenue number heads this off before it becomes a point of confusion.

The partners hadn't built this chart before their first buyer call, and pulling it together after the fact from twelve months of bank statements costs them a week they hadn't planned for. Every seller in this category should have it ready before the first serious conversation, not assembled reactively once someone asks.

A second buyer, found through Flippa's marketplace, has bought a seasonal business before and asks fewer clarifying questions about the revenue pattern itself, moving faster to client retention and staff continuity instead. That buyer's own experience with seasonal cash flow turns out to matter more to how quickly the conversation progresses than either platform's fee structure.

Both buyers ask the same thing: how many of the firm's preparers and reviewers are core season-only contractors versus full-time staff, and would the current team return next season under new ownership. The partners realize they don't have signed agreements with several key seasonal preparers, just an informal understanding built over years, and spend several weeks formalizing those relationships before serious diligence continues.

One of the six seasonal preparers has worked every January for over a decade and effectively runs the review process for junior staff. Losing that person would be a bigger operational risk than either buyer initially assumes, and it takes a direct conversation for the partners to realize how much informal training and quality control runs through her specifically.

The deciding factor is client authorization continuity: every client relationship requires fresh engagement letters and e-file authorization on file each season, and a buyer wants confidence that clients will re-sign with a new firm name on the letterhead. The partners who close successfully are the ones who introduce the buyer to their top twenty clients personally in the off-season, well before the next filing deadline, rather than leaving that introduction for the new owner to handle cold.

Those introductions, done calmly months ahead of the next busy season, turn out to matter more to the final price than either platform's fee schedule. A buyer who has already met your top clients face to face closes with real confidence instead of a hope that the relationships hold.

In hindsight, formalizing seasonal staff agreements and building a real off-season cash flow model a full year before listing, rather than during the sale process itself, would have shortened diligence meaningfully. Both of those fixes cost little and mostly take calendar time, which is exactly the resource a rushed seller doesn't have once a buyer is already asking.

The partners also wish they'd documented client tenure and referral sources earlier, since that eight-year average retention number turned out to be one of the strongest points in their favor once a buyer actually saw it laid out clearly.

Takeaways from this example:

• Show a monthly cash flow chart, not only an annual total, so buyers understand the tax-season concentration right away.
• Formalize agreements with seasonal preparers and reviewers well before you list.
• Build an off-season cash flow model a full year ahead of the sale rather than during it.
• Plan for fresh engagement letters and e-file authorization so clients re-sign under the new firm name.
