Carta vs Forge Inside A PE-Backed Tax Platform

A multi-state tax practice typically operates through entities registered in every state where it has a physical or economic presence, and each of those registrations needs to be current before shares tied to that entity can transfer cleanly. Pitfall: assuming the parent holding company's good standing covers every subsidiary automatically, when state-by-state registration is usually a separate, easy-to-miss requirement. Assign one person ownership of the state-by-state checklist rather than leaving it to whoever happens to notice a gap.

Like accounting roll-ups, a PE-backed tax platform often separates a management services entity from any state-licensed practice entities, and equity held by staff or acquired-practice owners typically sits in the MSO rather than the licensed side. Pitfall: running a tender that does not clearly distinguish which entity's equity is actually being offered. Put the entity distinction in the disclosure packet's opening paragraph, not buried in an appendix, so no one mistakenly assumes they are being offered a stake in the wrong entity.

Once entity and eligibility questions are resolved, Carta's tooling handles a sponsor-funded or treasury-funded buyout cleanly across the platform's various acquired-practice entities. Pitfall: configuring the tender before the sponsor's deal team has confirmed eligibility across every acquired practice, which invites disputes once the disclosure packet goes out.

If the platform wants to bring in additional institutional capital to fund a larger buyout than its own reserves support, Forge's buyer network operates at the holding company level, similar to how it would at any other PE-backed services roll-up. Pitfall: assuming a new co-investor's governance rights will mirror the original sponsor's without a separate negotiation.

Tax practices have an even narrower window than accounting firms generally, since the core January-through-April filing season leaves almost no bandwidth for anything else. Pitfall: scheduling any part of the disclosure or election process inside that window, which risks both rushed decisions from staff and genuine operational strain during the practice's busiest months.

A platform assembled from several small tax practices often inherits different accounting and payroll systems from each acquisition, which can make it surprisingly hard to produce a single, reliable picture of who holds what equity and what the platform can actually afford to pay out. Pitfall: assuming the corporate finance team's consolidated view is accurate without spot-checking it against at least a sample of the underlying acquired-practice records. Budget real time for this reconciliation step in the project plan rather than treating it as a quick data pull, since it is often the single slowest part of preparing for a multi-entity liquidity program.

Some states require individual tax preparer registration or specific credentials for anyone holding certain roles at a tax practice, separate from any broader ownership rule, and a change in equity structure can sometimes intersect with those requirements in ways worth checking early. Pitfall: treating this purely as a corporate ownership question without confirming whether any individual-level registration rules apply to the specific roles involved in the transaction. Cross-check this against every state the platform operates in, not just the state where the acquired practice being transacted is headquartered.

Sponsors running a tax roll-up typically expect to run this process more than once as the platform grows through further acquisitions, so treat the first program's documentation, the entity map, the eligibility criteria, the filing-season calendar, as infrastructure to reuse rather than a one-off project. Platforms that build this discipline early report meaningfully faster execution on their second and third liquidity events, mostly because nobody is rediscovering the same entity-mapping problem from scratch each time. As the platform matures, expect Carta to handle the steady stream of smaller, practice-level buyouts tied to individual owner retirements, while Forge gets reserved for the occasional larger event where the sponsor wants a new institutional co-investor to fund the next wave of acquisitions.

A wider marketplace comparison sits here too.

Reusable program infrastructure should include:

• An entity map showing which entity holds each block of equity, separating the management services entity from state-registered practices.
• A state-by-state registration checklist with one named owner rather than whoever happens to notice a gap.
• Written eligibility criteria that the sponsor's deal team has confirmed across every acquired practice.
• A calendar that keeps disclosure and election windows clear of the January through April filing season.
• A reconciled view of the legacy accounting and payroll systems inherited from each acquired practice.
