Two Ways a Tax Advisory Firm Can Structure Equity

Some tax firms spin out a separate C-corp for a specific line of business, a proprietary tax research tool, a multi-state nexus tracking platform, a broader advisory arm distinct from compliance work, and grant real stock options through that entity. This gives the specialist genuine ownership and dilution exposure, which tends to feel more valuable to a candidate weighing offers from firms that do offer real equity.

The tradeoff is setup cost: a separate entity needs its own governance, its own 409A valuation, and its own ASC 718 accounting if it reports under GAAP, distinct from the core partnership's books. That's real administrative weight for a firm that may only be granting equity to one or two people initially, so weigh it against how likely that entity is to grow into something that needed this infrastructure anyway.

A separate entity adds these requirements to the setup:

• Its own governance, distinct from the core partnership.
• Its own 409A valuation before any option is granted.
• Its own ASC 718 accounting if it reports under GAAP, kept apart from the core partnership's books.
• A realistic view of whether the entity will grow into something that needed this infrastructure anyway.

Other firms skip the separate entity and instead offer a phantom bonus or synthetic equity formula tied to the core practice's revenue or profit growth, without transferring real ownership or diluting the existing partners. This is faster to set up and avoids the governance overhead of a second entity entirely.

The tradeoff here is that a phantom formula doesn't carry the same psychological weight as real equity for some candidates, and it requires its own periodic revaluation and clear payout terms to stay credible, or it risks becoming just as opaque as an unmanaged option pool would be. A specialist who's turned down a phantom offer elsewhere for exactly this reason is worth taking seriously as a signal about how your own offer will land.

If the firm is building a genuinely separate, scalable technology or advisory product that could stand alone or attract outside investment eventually, real options through a spun-out entity make more sense, since that entity will need institutional-grade equity administration regardless of when the first grant happens. If the goal is purely retention within the existing practice, a phantom formula usually gets you there with far less overhead.

Be honest with yourself about which goal you're actually solving for, since building a separate entity's full governance structure just to retain one senior specialist is often more machinery than the situation calls for. Firms that skip this honest assessment often end up over-building for a retention problem or under-building for a real product opportunity.

G&A spend runs around 24% of revenue at many growth-stage professional services firms¹, and a controller earning the national median wage of $83,680² is a meaningful resource to protect from manual equity or phantom-formula tracking, particularly during the firm's own busy tax season when that same controller's time is under the most pressure.

Whichever approach you choose, avoid launching it right before your firm's own compliance deadlines, since the administrative setup competes directly with the busiest stretch of the year for tax practitioners specifically. A firm that tries to stand up a new equity process in February alongside a full compliance workload usually ends up doing both poorly, and the controller ends up absorbing the cost of that timing decision personally.

For a separate entity granting its first small option pool, compare each vendor's 409A turnaround, pricing and support against a finance function that's thin outside of tax season. Carta's deeper modeling and larger valuation bench matter more if the spun-out entity has raised outside capital and needs reporting that looks familiar to institutional investors reviewing the deal.

Ask each vendor directly how their team's availability shifts during the January through April stretch, since a support response that's fine in June may slow down exactly when your firm has the least bandwidth to chase it. A vendor that can't answer that question specifically hasn't worked with enough tax-season-sensitive clients to know it matters.
