Goodwill on Incorporation: The Tax Angle When You Turn Your Sole Trader Business Into a Limited Company

What Is Goodwill?

Goodwill is the value of your business over and above its physical, identifiable assets. It's the intangible worth that makes an established business more valuable than the sum of its vans, tools and stock. In a trade business, goodwill is built from things like your reputation, your established customer base and repeat clients, your trade name, your reviews and referral network, and the simple fact that the business is a going concern rather than a standing start.

If you've run a plumbing, electrical, roofing or building business for ten years and have a steady stream of work and a recognised local name, that business is worth more than a brand-new one with the same equipment. That extra value is goodwill — and when you incorporate, it doesn't simply disappear. It moves from you, the individual, into the new company, and that movement is a tax event.

How Goodwill Is Treated When You Incorporate

Incorporation is not a tax-neutral "upgrade" of the same business. In law, you (the sole trader or partners) are selling the business — including its goodwill — to a separate legal person: your new limited company. The company is buying the goodwill from you. That sale crystallises a capital gain on the goodwill in your hands, because you're disposing of an asset.

Because you and the company are connected, the transfer is treated as taking place at market value for tax purposes even if no cash actually changes hands. That's the core of why goodwill matters on incorporation: it's a disposal of a chargeable asset, and there are two common routes for dealing with the gain.

Route 1 — Sell the Goodwill and Create a Director's Loan Account

The first route is to formally sell the goodwill to your company at market value. The company owes you that amount, but rather than paying it out immediately (it usually has no cash to do so), the debt is credited to your director's loan account (DLA). You then draw that balance down over time as and when the company has the funds.

The key advantage is in extraction. Repaying a genuine director's loan is not income — it's the company settling a debt it owes you. So as you draw the balance down, there's no income tax and no National Insurance on those withdrawals. For an owner-manager who would otherwise take dividends or salary (both taxed), having a sizeable tax-free DLA to draw against is genuinely valuable.

The cost side is that selling the goodwill is a disposal for Capital Gains Tax. You pay CGT on the gain on the goodwill — and where the conditions are met, potentially at the Business Asset Disposal Relief (BADR) rate rather than the standard rate. But there's a major catch on BADR for goodwill, covered below, that catches most owner-managers out.

Route 2 — Use s162 Incorporation Relief

The second route is to claim incorporation relief under s162 TCGA 1992. Where you transfer the whole business as a going concern (with all its assets, other than cash, which you can keep) wholly or partly in exchange for shares in the company, the gain on the goodwill — and other chargeable assets — is rolled into the base cost of the shares you receive. You don't pay CGT now; instead the gain is deferred until you eventually sell the shares.

s162 relief is automatic if the conditions are met (you can elect out of it). It's clean and avoids an immediate tax bill, but it has a significant downside compared with Route 1: because the consideration is shares rather than a debt owed to you, you don't create a director's loan account to draw down tax-free. So you trade off the immediate tax deferral against losing that future tax-free extraction route. Which is better depends entirely on your numbers and how you plan to take money out.

The Big Restriction — No Corporation Tax Relief for the Company

Here is the trap that surprises most people. You might assume that, having bought goodwill from you, the company can write that goodwill down (amortise it) against its profits and get corporation tax relief — effectively a tax deduction spread over years. For goodwill purchased from a related party on incorporation, that is generally not the case.

Since 3 December 2014, a company gets no corporation tax relief for amortising goodwill (and certain other customer-related intangibles) that it acquires from a related individual or partnership on incorporation. The rules were tightened precisely because owner-managers were extracting cash via a DLA while the company also claimed amortisation relief — a double benefit the government closed down.

A limited, partial relief was reintroduced from April 2019, but only in narrow circumstances — broadly where the relevant goodwill is acquired together with qualifying intellectual property (such as registered trade marks or patents), and subject to a cap. For most everyday trade businesses, where the goodwill is pure customer-base and reputation goodwill with no qualifying IP attached, the company will get no amortisation relief. Do not build your incorporation plan on the assumption that the company can write the goodwill off — it usually can't.

Does BADR Apply to Goodwill on Incorporation?

Business Asset Disposal Relief (the relief formerly known as Entrepreneurs' Relief) reduces the CGT rate on qualifying disposals. You might hope to apply it to the gain on goodwill under Route 1. In most owner-manager cases, you can't — and this needs flagging clearly.

Since 3 December 2014, BADR is specifically denied on goodwill transferred to a close company that you control. Because a typical incorporation involves you selling your business goodwill to a company you own and control, the relief is blocked on that goodwill. The narrow exception is where you dispose of all (or substantially all) of your shares in the company — for example, a genuine sale or retirement scenario — rather than continuing as the controlling owner-manager.

So for the standard owner-manager who incorporates and carries on running the business, the gain on the goodwill is taxed at the standard CGT rates, not the BADR rate. Plan on this basis. If a calculation assumes the lower BADR rate on incorporation goodwill, double-check it carefully — it's a very common error.

Valuation — Get It Right and Be Able to Defend It

Whichever route you take, the goodwill must be transferred at a justifiable arm's-length market value. This is not a number you can pluck out of the air. HMRC actively scrutinise goodwill valuations on incorporation, and inflated figures — designed to maximise a tax-free director's loan — are a known target for enquiry.

For a trade business, goodwill is often valued by reference to maintainable profits with an adjustment for the proprietor's own labour (the so-called "super-profits" — the return above what an owner could earn working elsewhere), or by reference to a multiple based on the sector. A business whose value depends almost entirely on the owner personally turning up to do the work may have little transferable goodwill at all — and HMRC know this.

• Get a professional valuation from an accountant or valuer who can document the basis and assumptions.
• Keep the evidence — accounts, profit history, the valuation methodology — so you can defend the figure if asked.
• Consider applying for non-statutory clearance from HMRC on the valuation before you complete, so you have certainty rather than a nasty surprise years later.
• Be realistic: an over-egged valuation that's later reduced by HMRC can leave you with an overdrawn director's loan account and unexpected tax consequences.

The Director's Loan Interaction — Why It Improves Extraction

The reason Route 1 is attractive comes down to how money leaves a company. Normally, to get cash out of your Ltd you take salary (income tax plus NI) or dividends (dividend tax). Both reduce what reaches your pocket. A director's loan repayment is different: the company is paying back money it genuinely owes you, so there's no income tax and no NI on the repayment.

By selling goodwill into the company and crediting your DLA, you create a pot of value you can draw against tax-free as the company generates cash, in addition to your normal salary and dividends. You pay the CGT on the goodwill once, up front (at standard rates for most owner-managers), but then the extraction itself is clean. Over several years this can materially improve the total tax efficiency of how you take money out — which is exactly why the rules around amortisation relief and BADR were tightened.

Worked Example

Priya runs an established electrical contracting business as a sole trader. Her accountant values the transferable goodwill at £60,000, supported by a documented valuation based on maintainable super-profits. She incorporates and sells the business, including its goodwill, to her new company, Priya Electrical Ltd, which she wholly owns.

She chooses Route 1. The £60,000 is credited to her director's loan account. The base cost of the goodwill is treated as nil (she built it up rather than buying it), so the gain is £60,000. After deducting her annual CGT exempt amount, she pays CGT on the balance at the standard rate — not the BADR rate, because the goodwill is transferred to a close company she controls and she's keeping her shares.

The company gets no corporation tax relief for amortising the goodwill, because it's pure customer/reputation goodwill bought from a related party with no qualifying IP attached. But Priya now has a £60,000 director's loan she can draw down over the coming years with no further income tax or NI as the company builds up cash — on top of her salary and dividends. She paid CGT once; the extraction is tax-free.

Had she instead claimed s162 incorporation relief, she'd have paid no CGT now (the gain rolling into her shares), but she'd have no DLA to draw against — so all future extraction would be via taxed salary and dividends. Which route wins depends on her cash needs, her marginal rates and how long she plans to keep the company. This is exactly the kind of decision worth modelling with an accountant before you complete the incorporation.
