Independent buyout valuations when a partner joins or leaves — one number both sides can accept.

A partnership buyout valuation establishes the market value of a partner's fractional interest when a partner is admitted to or retires from a partnership — including professional practices in medicine, accounting, law and the trades. Prismi prepares independent, evidence-led buyout valuations that price the specific interest, address goodwill directly, and give both sides a single supportable number their accountants can paper the CGT consequences around.

When a partnership buyout valuation is required

A buyout valuation is required whenever a partner's fractional interest changes hands and there is no arm's-length market to price it — admitting a new partner, retiring a founding partner, a death or permanent incapacity that triggers the deed, or an internal transfer between existing partners. These transactions sit in a gap that nobody owns. Business brokers offer rules of thumb — cents in the dollar of recurring fees for accounting practices, multiples of billings for medical practices — that were never built to price a fractional interest in a specific firm under a specific deed. The partnership's own accountant usually acts for the firm and for several of the individual partners, and cannot be independent as between an incoming and an outgoing partner. What both sides need is a market valuation of the specific interest, at the specific date, prepared by someone with no stake in which way the number falls.

When the deed and market value disagree

Many partnership deeds contain a price mechanism — a multiple of average distributions, net assets at book value, the capital account balance, or 'fair value' as determined by the firm's accountant. As between the partners, the deed generally governs contractually: partners are bound by the mechanism they signed. But the ATO is not a party to the deed. For tax purposes the transaction is tested against market value, and where the parties are not dealing at arm's length, the market value substitution rules can replace the deed price with market value — so a formula price below market can still produce a capital gain calculated at market value for the outgoing partner. Stale formulas compound the problem: a mechanism drafted twenty years ago may bear no relationship to what the firm is worth today. Where the deed and market value diverge, our report states both — the value under the deed's basis and market value proper — and quantifies the gap so the lawyers and accountants can deal with it deliberately rather than discover it later.

Goodwill in professional practices — and what walks out the door

The hardest question in a professional-practice buy-in is whether goodwill exists at the practice level or attaches to the individuals. A medical practice with strong systems, premises, recall processes, employed support staff and a brand patients return to has transferable goodwill; a practice that is essentially one practitioner's personal exertion has very little. In accounting and legal firms, recurring compliance work and institutional client relationships behave differently from advisory relationships that follow an individual partner. In the trades, contracts, prequalifications and licences held by the entity are transferable; those held personally are not. An incoming partner should pay only for goodwill they actually acquire — goodwill that survives the departure of any one individual. Our reports separate practice goodwill from personal goodwill, test the split against the evidence (client and patient concentration, referral sources, who holds the key relationships), and factor in whether the deed's restraint-of-trade terms actually protect the goodwill being purchased.

Discounts on a partner's share — when they apply and when the deed excludes them

A 20% partnership interest is not automatically worth 20% of the firm. On open-market principles, a fractional interest with no control and no ready market would attract discounts for lack of control and lack of marketability. But buy-ins and buyouts are usually not open-market transactions — they are internal transfers within a functioning firm where the deed itself provides the market: a purchase obligation on continuing partners, an entitlement to a pro-rata profit share, a seat in management. Many deeds exclude discounts outright and require a pro-rata share of whole-firm value. Where the deed is silent, context governs. An incoming partner acquiring full partner rights and a proportionate profit share is in a different position from a hypothetical buyer of a passive fractional interest on the open market. Our reports address the question explicitly — whether discounts apply in this transaction, at what quantum, and why — rather than defaulting to standard discounts the context does not support.

One number both sides can accept

The alternative to an independent valuation is two advocacy valuations — the outgoing partner's high number and the incoming partner's low one — followed by months of negotiation and, often, a damaged relationship inside the firm. Duelling valuations cost roughly twice as much and resolve nothing on their own. A single independent valuation, engaged jointly by the partnership with both sides receiving the same report, gives the negotiation a defensible anchor. Our fees are fixed at engagement and never contingent on the outcome, and the conclusion is determined by methodology and evidence, not by which party signed the engagement letter. Where either side asks for a target value, we will say so and decline the engagement on those terms. That independence is what makes the number usable by both sides — and defensible if the ATO later reviews the transaction.

The tax consequences your accountant will need to paper

For CGT purposes each partner is treated as owning a fractional interest in each partnership asset, so a retiring partner's exit is a disposal of those fractional interests — a CGT event on each, including any interest in goodwill. Where the parties are related or not dealing at arm's length — common in family partnerships and deed-priced transfers — market value substitution can apply, which is why the value must be supportable rather than convenient. The retiring partner may look to the small business CGT concessions under Division 152, where eligibility can turn on substantiated market values through the maximum net asset value test and the active asset test. The incoming partner's payment sets their cost base in the fractional interests acquired, including any amount attributed to goodwill and to work in progress. Our report gives the accountant the market value evidence for each of these positions. The tax application itself is theirs — Prismi prepares independent valuations only and is not a registered tax agent; we do not provide tax or legal advice.

Documents we need, and the right tier

Most partnership buyout valuations sit at the Comprehensive tier (from $3,995 + GST, 15–25 business days). Straightforward interests in smaller trades partnerships may fit the Essential tier (from $1,495 + GST, 10–14 business days). Where the transaction is between related parties, the deed and market value diverge materially, or small business CGT concessions will be claimed on the exit, the Defensible Valuation File (from $8,995 + GST, 25–35 business days) is the right level. Where the partners want to see how the number moves under different goodwill and discount treatments before committing, the Valuation Range & Scenario Review premium engagement is designed for exactly that. If the buyout price must be established at an earlier date, a retrospective surcharge of $495 per historical date applies.
