When people talk about buying or selling a business in London, they often mean one of two places with very different tax systems. We work with owners and investors in both the UK capital and in London, Ontario. The fundamentals of valuation, diligence, and deal structure are universal, but the tax playbook is not. Smart structuring can shift net proceeds by tens or even hundreds of thousands, and in some cases it is the difference between a deal that closes and a deal that stalls.
What follows is the framework our team at Liquid Sunset Business Brokers leans on when guiding clients through a sale or acquisition in London. The aim is practical clarity. If you are scanning the market for an off market business for sale, weighing when to exit your own company, or trying to compare businesses for sale London Ontario against options in the UK, use these notes as a compass for early decisions, then bring in a specialist tax adviser to run the numbers on your specific facts.
First decision that drives tax: asset sale or share sale
Almost every discussion starts here. Whether you are eyeing a small business for sale London, a larger set of companies for sale London, or a family enterprise in south west Ontario, the choice between an asset deal and a share deal shapes the tax profile for both buyer and seller.
In an asset sale, the buyer acquires selected assets and assumes selected liabilities. In a share sale, the buyer acquires the equity of the target company and inherits everything in it, good and bad. Buyers tend to prefer asset deals because they can pick what they want and reset tax bases on depreciable assets. Sellers tend to prefer share deals because they can achieve capital gains treatment, simplify the handover, and sometimes avoid sales tax frictions.
How this plays out in London UK and London Ontario differs, so we split the analysis.
Buying or selling in London, UK
VAT and the transfer of a going concern
A surprising number of owner managers still think a business sale automatically triggers 20 percent VAT. Often it does not. If the sale is structured as a transfer of a going concern - TOGC - and conditions are met, the transfer is outside the scope of VAT. In plain terms, no VAT is charged on the sale. The key tests include that the business is transferred as a going concern and the buyer is a taxable person who will use the assets to carry on the same kind of business. Property transfers within a TOGC can be trickier, especially when the seller has opted to tax the property. Plan early, because one missing registration or an incorrect option to tax can push an unnecessary VAT cost into the deal that lenders will not finance.
For pure share sales, VAT does not apply to the purchase of shares. Instead, watch the indirect effects, such as irrecoverable input VAT on deal fees, unless certain structuring steps allow VAT recovery.
Stamp duty and SDLT
In the UK, a share purchase attracts stamp duty at 0.5 percent of the consideration, rounded up to the nearest 5 pounds. On a 3 million pound deal, that is 15,000 pounds, which is rarely a deal breaker but should be in the funds flow. For asset deals that involve land or buildings, Stamp Duty Land Tax - SDLT - applies at non residential rates. The current bands and rates change occasionally, but the top rate on higher value non residential property is 5 percent. We once saw a buyer negotiate a lower property allocation within an asset deal, not to reduce the overall purchase price, but to reduce SDLT, only to discover that the seller’s capital gains tax exposure increased by more than the SDLT saved. Change one variable in the tax mix and Liquid Sunset – Companies for Sale in London something else often moves.
Capital gains and Business Asset Disposal Relief for sellers
From a seller’s perspective, the headline question is the rate that applies to their gain on a share sale. Where conditions are met, Business Asset Disposal Relief - formerly Entrepreneurs’ Relief - can reduce the capital gains tax rate on qualifying gains to 10 percent, subject to a lifetime limit. Sellers need to have held at least 5 percent of the ordinary share capital and voting rights for a qualifying period, among other conditions. The relief looks simple on paper, yet it is common to find that a past reorganization, growth share arrangement, or loan note structure quietly knocked the shareholding below 5 percent. Audit the cap table months before going to market, not while the buyer’s lawyers are drafting completion documents.
For corporate sellers with substantial shareholdings in trading subsidiaries, the Substantial Shareholdings Exemption can eliminate corporation tax on gains when selling shares in certain circumstances. This exemption does not apply to asset sales. If a group is contemplating a pre sale hive down of a trade into a new company to try to capture the exemption, be careful with timelines and trading tests. HMRC will expect the structure to have commercial substance, not just an overnight attempt to engineer an exemption.
Buyer side tax reliefs and pitfalls
For share deals, buyers inherit the target company’s tax history. That includes carried forward losses, but UK loss rules now restrict the use of carried forward losses after certain changes in ownership or major changes in the nature or conduct of the trade. Buying a distressed company for its tax losses is rarely as valuable as rumor suggests. On the other hand, embedded capital allowances on plant and machinery can be attractive in asset deals. The buyer and seller usually agree a section 198 election to set the disposal value of fixtures, which prevents double relief and gives certainty. Miss the election window, and it turns into a post completion headache.
Intangibles and goodwill demand special attention. The UK has altered the tax treatment of goodwill amortization multiple times in the last decade. Relief is restricted and, for many trades, unavailable on general goodwill. Relief may be available for qualifying intellectual property at a fixed rate. The conclusion is not that goodwill is never tax efficient in the UK, but that the book value you record is not the deduction you should expect. Model cash taxes carefully.
Earn outs, loan notes, and deferred consideration
Earn outs are common in smaller UK deals. The tax timing depends on whether the earn out is represented by a right to receive unascertainable consideration, by loan notes, or by cash subject to targets. Many sellers prefer qualifying corporate bond loan notes where a share for loan note exchange can fix the tax point and rate. Small wording changes decide whether those notes qualify. Buyers should also consider whether interest on deferred consideration is deductible and how much of the earn out is at risk of being treated as employment related if the seller is staying on. HMRC looks closely at retention arrangements that smell like disguised remuneration.
Cross border buyers and non resident sellers
Non resident sellers pay UK tax on UK land and certain property rich shares, but the UK does not generally withhold tax on a standard share sale by a non resident absent specific assets. Cross border buyers should check permanent establishment risks and VAT registration thresholds from day one. The tidy SPA clause that says the buyer will form a VAT group post completion will not backdate recoverability of input VAT on fees. Agree who bears irrecoverable VAT on transaction costs up front.
Buying or selling in London, Ontario
Several of our clients search for businesses for sale London Ontario while comparing opportunities in the UK. The Canadian system has different pressure points. If you plan to buy a business in London Ontario or to sell a business London Ontario, start with the same asset versus share decision, then layer on Canadian and Ontario specifics.
HST on asset deals, not on share sales
In Ontario, asset purchases of taxable supplies are generally subject to 13 percent HST unless an exemption applies. The most common relief is the election to treat the sale as the supply of all or substantially all of the property necessary to carry on a business, sometimes referred to as the closely related 167 election under the Excise Tax Act. If the buyer is a GST HST registrant and both parties jointly elect, HST does not apply to most assets in the sale of a going concern. The election paperwork must be filed, and certain assets such as real property and inventory might still have specific wrinkles. Share sales are typically exempt from HST. The difference can swing cash needs on closing by hundreds of thousands.
Land transfer tax on property assets
Ontario levies land transfer tax on real property purchases. The City of London does not impose an additional municipal land transfer tax - that is a Toronto feature - but the provincial tax still applies. In an asset deal where a building is part of the sale, factor in LTT. In a share deal, LTT usually does not apply unless a partnership or certain land rich entities are involved. We have seen buyers push for a share deal purely to avoid LTT on a property heavy business. The seller then requested a price bump to reflect perceived risk and reduced basis in assets. The right answer sits in the spreadsheet, not in preference alone.
Capital gains, the Lifetime Capital Gains Exemption, and the new inclusion rules
For individual sellers of qualifying small business corporation shares, Canada offers the Lifetime Capital Gains Exemption - LCGE. If the shares meet the active business and asset tests, an individual may shelter a large amount of gains from tax up to their remaining LCGE room. This can transform outcomes for owners of a small business for sale London Ontario. It requires planning. Purify the corporation of passive assets, confirm that 90 percent of assets are used in an active business at the time of sale, and meet the 24 month holding and usage tests.
Canada’s capital gains inclusion rate changed for dispositions taking place after June 2024 in many cases. For individuals, gains above a specified threshold in a year may be included at two thirds rather than half. For corporations and many trusts, the inclusion rate moves to two thirds. The net effect for sellers is that the tax on capital gains can be materially higher than before for some sellers. This makes the LCGE more valuable and can rekindle interest in earn out deferrals and vendor take back structures that spread gains across years. Always check current rules with a Canadian tax adviser because rates and thresholds can shift.
Asset deals and CCA on depreciable property
In asset purchases, buyers set new tax cost for depreciable assets and can claim Capital Cost Allowance - CCA - over time. Goodwill and many intangibles fall into Class 14.1, generally depreciated at 5 percent declining balance with a half year rule in the year of acquisition. Some buyers overestimate the immediate deduction for goodwill, only to learn that the deduction is gradual and sensitive to purchase price allocation. Craft the allocation with care. It should reflect commercial value and withstand CRA review. A reasonable allocation also bridges valuation gaps between buyer and seller since different asset classes carry different tax attributes.
Share purchases and loss restrictions
If you buy shares of a Canadian company, an acquisition of control can restrict the use of non capital losses and certain tax attributes. Post acquisition, using pre existing losses is limited to income from the same or similar business the company carried on before the change of control. Asset protection reorganizations ahead of closing can trigger unintended control changes if done hastily. We once paused a deal for a buyer who thought they were stepping into usable losses. A quick review of prior ownership changes revealed those losses were already restricted. The purchase price was adjusted before the letter of intent turned into a binding agreement.
Withholding and clearance certificates for non resident sellers
If a non resident sells taxable Canadian property - which can include shares of a private corporation that derives significant value from Canadian real property - the buyer may be required to withhold a portion of the purchase price unless the seller provides a clearance certificate from the Canada Revenue Agency. The withheld amount can be large in relation to the expected tax. Non resident sellers planning to list a business for sale in London Ontario should start the clearance process early. Buyers should include a holdback mechanism if the certificate cannot be produced by closing.
Earn outs, vendor take back notes, and price adjustments
In Canada, earn outs and vendor take back loans are common in the sale of owner operated businesses. The tax handling depends on whether the earn out is eligible for the cost recovery method. If structured correctly, tax can be paid on earn out payments as they are received rather than on an estimate at closing. This reduces the risk of paying tax on revenue that never materializes. The cost recovery method is not automatic. The wording in the purchase agreement matters, as do the nature of the metrics and the seller’s accounting method.
Comparing London UK and London Ontario for buyers
People often ask whether the UK or Ontario offers the more tax efficient route to buy a business. The answer depends less on headlines and more on your plan.
If you intend to roll up a cluster of shops or clinics and you need step ups in asset basis to drive cash tax relief, Ontario asset deals with CCA can be attractive. HST is a manageable cash flow item if the 167 election applies. In the UK, asset deals give capital allowances on fixtures but a more limited route for goodwill relief, and SDLT on property can be punchy. If you are building a platform and want clean share purchases to preserve goodwill and relationships, UK share deals can be efficient, but the details of loss restrictions, stamp duty, and intangible rules matter.
Financing also interacts with tax. Interest deductibility regimes in both countries have tightened. The UK’s Corporate Interest Restriction can cap relief even in mid sized deals. Canada’s interest deductibility changes and thin capitalization rules can limit relief for heavily levered buyers. If your model leans on debt, build tax capacity tests into diligence.
Preparing a sale with tax in mind
We use the same playbook whether the mandate is an off market business for sale in the UK or a bakery chain in London Ontario. Preparation beats negotiation. Owners who get tax ready six to twelve months before going to market tend to close faster and keep more of the price they win.
- Clean the cap table and confirm eligibility for reliefs. In the UK, check Business Asset Disposal Relief conditions. In Canada, test LCGE eligibility and clean out passive assets. Map and document sales tax positions. UK TOGC conditions and options to tax should be squared away. In Ontario, confirm GST HST registration and prepare the 167 election details for an asset deal. Decide early between share and asset framing. Align this with buyer appetite, valuation, and tax outcomes. Do not leave it to the last week. Allocate price intelligently. Draft a purchase price allocation that is logically defensible and mutually efficient. Tidy employee arrangements. Bonuses tied to completion, option exercises, and post sale consulting fees can shift amounts from capital to income if drafted carelessly.
Buyer diligence with tax eyes open
Investors considering buying a business in London or buying a business in London Ontario should fold tax into their first pass. It is not just the accountant’s annex in the data room. A few focused checks up front can save weeks later.
- Identify exposure to indirect taxes. For UK targets, confirm whether the business is registered for VAT and how input VAT has been treated on large items. For Ontario, check HST compliance and any QST or PST footprints from cross border sales. Test payroll and worker status. UK IR35 issues and Canadian contractor misclassification can result in arrears, penalties, and reputational risk. Review tax attributes as if they were cash. Validate loss carryforwards, capital dividend account balances in Canada, and capital allowances pools in the UK. Inspect property taxes and transfer taxes. Embedded property tax appeals, options to tax, and historic SDLT or LTT positions can move value. Confirm withholding and residency. Cross border investors must check treaty relief, permanent establishment risks, and any required clearance certificates.
How Liquid Sunset handles London versus London Ontario
We see a wide spectrum of owner motivations. Some clients want to sell a business London Ontario and retire to the lake within a year. Others want to buy a business in London, grow it for three years, then bolt it to a strategic. The role of Liquid Sunset Business Brokers is to match the commercial endgame with a tax path that does not leave money on the table.
On a recent small business for sale London file, a buyer wanted an asset deal to rebase equipment and limit liabilities. The seller qualified for Business Asset Disposal Relief on a share sale and faced a notably higher tax bill in an asset exit. Rather than fight, we priced two structures. The buyer agreed to a modest price premium for a share purchase plus a targeted indemnity for pre completion VAT and payroll risks. Tax saved by the seller funded the indemnity escrow. The deal closed with less friction and fewer advisors in the room.
In Ontario, we helped a family selling two locations of a services company. The corporation had built up investments that jeopardized LCGE eligibility. Twelve months before going to market, we moved passive assets out, tuned working capital, and documented active business use. At closing, each shareholder sheltered a large slice of their gain under the LCGE. The buyer opted for a share purchase to avoid HST and to keep customer contracts intact. Because both parties planned ahead, there was no scramble for CRA clearance or rushed elections. That is the difference preparation makes.
Clients often ask whether Liquid Sunset Business Brokers can source an off market business for sale that avoids an auction premium and leaves more room to solve for tax. Off market work does not magically remove taxes, but it gives breathing room to structure a deal without the pressure of a competitive timetable. That extra time is when the 167 election gets filed properly, when the section 198 election is agreed sensibly, and when earn out clauses are drafted to achieve the intended tax results.
A word on valuation, price, and post tax proceeds
Price, terms, and tax form a triangle. You rarely optimize all three. If you, as a seller, insist on the highest top line with no earn out, be prepared to accept a structure that might cost more in tax. If you, as a buyer, must have an asset deal for risk reasons, expect to reflect the seller’s tax delta in your offer or compensate elsewhere, perhaps with a vendor take back note at a fair rate.
Run scenarios. In a 5 million pound UK share sale, a qualifying owner might pay 10 percent on most of the gain with BADR. If the same economics were forced into an asset sale inside a company, followed by a dividend to the owner, the combined corporation tax and dividend tax could produce a materially higher leak. In Ontario, a 4 million dollar share sale where each owner can claim LCGE may produce an after tax outcome that beats an asset sale by a wide margin. That gap can justify a concession on working capital targets or a longer transition period.
Practical edges that catch people out
Every market has its quirks. Here are a few edges we see repeatedly in London and London Ontario:
- UK property with an option to tax inside a TOGC. The buyer must notify and opt correctly or VAT becomes due unexpectedly. Canada’s half year rule for CCA. Buyers model a full year of CCA and then discover they only get half the normal claim in year one. Employee share options near closing. Exercises can taint shareholding tests for BADR or LCGE if not timed and documented carefully. Deal costs and VAT or HST. Who can recover, who cannot, and who bears irrecoverable tax should be agreed in writing. Working capital true ups that adjust the price post closing. The tax character of that adjustment can differ for buyer and seller. Do not assume symmetry.
Bringing the threads together
Whether you are scanning listings for a small business for sale London or shortlisting businesses for sale London Ontario, treat tax as a design constraint, not an afterthought. The earlier you decide on asset versus shares, map sales taxes, and confirm eligibility for reliefs, the smoother the rest of the transaction will feel. Buyers who think about VAT TOGC or HST elections before issuing a letter of intent tend to make cleaner offers. Sellers who tidy their corporate structure and cap table twelve months out tend to command better prices and keep more of what they earn.
Liquid Sunset Business Brokers spends as much time on this kind of pre work as on the visible negotiation. It is not glamorous, but it is what gets deals over the line with both sides feeling they won. If you are getting ready to buy a business in London or to buy a business in London Ontario, or if you are preparing to sell a business London Ontario and want to understand how your net proceeds could vary by structure, bring us your facts. We will show you the forks in the road and help you pick the one that fits your goals.
And if your ideal target is not on the market, we know how to find it. Off market does not mean off the grid. It means conversations where tax planning gets the time it deserves, and your deal closes on terms that make sense after tax, not just before.
