The best deals rarely look tidy on paper. They take shape across lawyer boardrooms on Dundas Street, in back offices near the 401, and over coffee with owners who built something real and now want to see it carry on. If you plan to buy a business in London Ontario, the tax angle can turn a fair price into a regrettable one, or a stretch purchase into a company you’re proud to grow for the next decade. The work sits in the details: choosing the right structure, understanding what exactly you’re buying, and sequencing the transaction so the Canada Revenue Agency remains a spectator rather than the loudest voice in the room.
I have yet to see two identical deals. But the patterns repeat often enough that it’s possible to map the terrain. What follows is a practical guide to tax considerations that consistently move the needle for buyers in and around London, shaped by the way deals actually get done here.
The fork in the road: share purchase or asset purchase
Every serious negotiation in London reaches the same early choice, share purchase or asset purchase. The difference sounds technical. It dictates tax outcomes long after the champagne goes flat.
In a share purchase, you acquire the owner’s shares of the company. The legal entity continues as if nothing changed. Contracts and employees stay put, licenses remain valid, vendor relationships carry on, and the business keeps its tax pools. From a seller’s perspective, this is often attractive because individuals can frequently access the lifetime capital gains exemption on qualified small business corporation shares, cutting or eliminating personal tax on the sale. That preference shapes your deal dynamics. If you want the seller to stick with a share sale, you may earn some leverage for other terms like vendor take-back financing, transition consulting, or a price break.
For you as a buyer, a share deal has trade-offs. You inherit the corporation, good and bad. That includes historical tax exposures, sales tax assessments that are still within audit windows, and any employment claims waiting to surface. You also give up immediate writeups on many assets, because you are buying shares, not the assets inside. Depreciation continues from where the company left off, which lowers your near-term tax shield compared with buying assets directly.
In an asset purchase, you buy specific assets and assume specific liabilities, often through a new corporation you set up. You get a fresh tax basis in the assets at the prices allocated in the purchase agreement. That can be a significant win. Allocate correctly, and you can claim capital cost allowance on depreciable assets and amortization on eligible intangibles such as customer lists, contracts, or non-compete agreements. You also avoid most legacy liabilities since the seller keeps the historical entity. Contracts must be assigned, permits reissued as needed, and employees rehired or novated. All of that adds friction, but it can be worth it for the clean start and stronger tax shield.
I have seen buyers overpay for shares because the headline figure looked lower, only to spend the next four years wishing they had insisted on assets after the first CRA audit question about a pre-closing HST issue. In other cases, share purchases made perfect sense, for example a regulated health clinic where transferring patient records and professional corporation structure made asset flow-through impractical. The right path responds to the business model, regulatory overlays, and the personality of the counterparty sitting across the table.
The role of business brokers, and when to bring tax into the conversation
Local intermediaries shape expectations from day one. Many business brokers London Ontario market businesses as “share sales preferred” because sellers want the gains exemption. That’s not a mistake; it is a starting point. If you plan to buy a business London Ontario and you see “share sale,” do not read it as non-negotiable. Read it as: the seller will need compensation if you push for assets.
Brokers contribute useful market intel. They know whether comparable deals in the London corridor skew toward shares or assets in your industry, and what concessions made those deals work. They are not tax advisors, though. The tax structure should migrate from the term sheet into the purchase agreement with care. If you are buying a business in London, get your accountant in the mix as soon as you have enough details for a preliminary model. Waiting until the purchase agreement is 90 percent done is how tax leakage sneaks in.
Pricing the purchase, then allocating the price
Assume the purchase price for a mid-market HVAC company in London is 3.5 times normalized EBITDA, or roughly 1.75 to 2.5 million given the size of many local operators. If you go the asset route, how you allocate that number across inventory, equipment, vehicles, goodwill, and other intangibles will decide the speed of your tax deductions and, for the seller, the mix between business income and capital gains. Canada’s tax rules require both sides to use reasonable, consistent allocations. Reasonable does not mean random.
Inventory is expensed as sold, so placing too much value there offers little early-stage benefit. Equipment in Class 8 can be depreciated, with half-year rules in year one. Vehicles have their own limitations, especially passenger vehicles with prescribed caps. Goodwill and customer relationships can sit as Class 14.1 with a fixed rate of amortization. A well-structured allocation leans toward intangibles you can amortize steadily without triggering large recapture for the seller.
With a share deal, you sidestep allocation, but you should still analyze the company’s tax attributes. Look for undepreciated capital cost balances on major classes, non-capital losses, and scientific research and experimental development credits, if any. Give them a haircut for usability. A dollar of loss carryforward is not a dollar of value if you cannot practically use it inside the continuity restrictions and with future profit levels. I have discounted losses by 50 to 75 percent in models to stay conservative.
HST, PST, and the deceptively simple Ontario factor
Ontario harmonized sales tax simplifies life compared with split GST and PST provinces, but it still trips up buyers. In an asset deal, check whether the acquisition qualifies as a supply of a business or part of a business that can be purchased without HST under the section 167 election. If both parties are registrants and the sale meets the conditions, completing the election avoids cash flow crunch and later input tax credit claims. I have seen buyers wire 200,000 in extra HST on a rushed closing without the election, only to file for credits and wait months for the refund. When you are financing payroll and fuel, that delay stings.
In a share sale, HST usually does not apply to the shares themselves, yet HST exposures within the company carry forward. That means reviewing recent HST filings, reconciliations, and any outstanding correspondence with CRA is part of diligence, not a courtesy. Businesses with retail or construction components in London often have more complex HST footprints due to rebates, mixed-use assets, or place-of-supply rules. Sloppy HST histories do not kill deal value, but they should change your price or insistence on indemnities.
Payroll, WSIB, and the drag of inherited systems
Owners sell because they want relief from complexity. Buyers inherit systems, and those systems influence tax. I once bought into a service business where payroll remittances were timely but classifications were off. Contractors were treated as independent when they met CRA tests for employees. In a share purchase, that classification risk is your risk, including CPP/EI assessments and penalties. In an asset deal, you have a chance to rebuild clean structures. That means issuing new employment contracts, standardizing vacation accruals, and aligning WSIB ratings. These do not show up in the broker’s teaser, but they shape your effective tax rate and cash outflows.
Ontario’s WSIB is not an income tax, but it feels like one when premiums spike due to classification errors. Audit histories matter. Ask for the last three years of WSIB correspondence, rating changes, and any outstanding claims. Build an accrual for clawbacks if you are taking shares and the claims tail looks heavy.
Vendor take-back notes, earnouts, and their tax ripples
Financing terms hide tax consequences. A vendor take-back (VTB) note can bridge the gap between what you can afford and what the seller expects. It also smooths tax for the seller through a capital gains reserve on share sales or a reserve on certain asset dispositions, letting them recognize proceeds over multiple years. That concession can let you bargain for a lower interest rate on the VTB, or more favorable security.
Earnouts require special attention. If you link part of the price to future performance, both sides should understand how those amounts will be taxed when paid. For share sales, earnouts can, under the right structure, be treated as additional capital gains. Design them poorly and you can create income that loses favorable rates. In asset deals, earnouts tied to revenue or margin can be matched to income inclusions for the seller, raising their effective rate and making them fight for a higher headline price. Skilled drafting is worth more than bravado here.
On your side, the VTB’s interest is deductible if the borrowed funds clearly relate to acquiring income-producing property. Keep a clean chain of documentation. I have seen smarter-than-average buyers mix operating line advances with VTB payments in a single account, then spend hours with their accountants proving use-of-funds to CRA. Segregate accounts: operating cash here, acquisition financing there.
Working capital targets and tax traps in the closing balance sheet
The letter of intent often includes a normalized working capital target. Plenty of deals stumble over what “normalized” means, and tax is part of the tension. Include HST receivable or exclude it? Count corporate tax installments as a current asset or remove them as seller property? There is no single rule, but consistency matters. I prefer to set a specific list of included accounts. HST net positions should be excluded from the target and settled separately, since you do not want to pay the seller for their input tax credits or inherit their net HST payable.
Inventory valuation affects both tax and price. Ensure the method at closing matches the method used historically: FIFO, weighted average, or specific identification where appropriate. A sudden switch is an easy way to funnel value from one side to the other under the cover of “policy change,” and it will have tax implications when you expense that inventory post-close.
Choosing your acquisition vehicle
Most buyers form a new Ontario corporation to complete the purchase. That gives liability protection and tax flexibility. The new company can elect a functional year-end that meshes with the seasonality of the business, for example a late fall year-end for a landscaping company to reconcile revenue and costs cleanly. If you have other businesses, a holding company above the purchasing company allows tax-efficient extraction of surplus through intercorporate dividends and prepares you for future reorganizations.
Family trusts and individual ownership sometimes enter the conversation. Trusts help with income splitting and future multiplication of the lifetime capital gains exemption when you eventually sell, subject to changing rules and attribution constraints. The cost of extra complexity should be justified by realistic exit plans. I meet many owners who paid for intricate structures during the purchase, then never used them because they never sold shares of a qualified small business corporation. Build for what you are likely to do, not what looks clever on a whiteboard.
Amortizing intangibles that actually exist
Too many asset deals toss a giant number into “goodwill,” then call it a day. That approach leaves tax value on the table. You might be buying customer contracts with defined terms, proprietary processes, non-compete agreements from the seller, a tradename with longevity, or a domain with measurable traffic. Each of these can sit in Class 14.1, but separating them with reasonable allocations can help you justify amortization patterns and support valuations if CRA asks. Document the basis: churn rates on the customer list, market evidence for the tradename, and any analytics that show domain value.
On the flip side, do not fabricate assets to force amortization. If a key supplier relationship hinges on the founder’s personal charisma and cannot be assigned, it is not an asset you can claim. Put it in the narrative risk analysis and price accordingly, not in the tax pools.
The quiet importance of pre-closing reorganizations
Sometimes the seller’s company holds assets you do not want, such as a building on Veterans Memorial Parkway or a pile of investments parked in a corporate brokerage account. Pre-closing rollouts can strip those away so you buy the operating business cleanly. These reorganizations take time and require tax elections and valuations. If you compress the timeline, you will find yourself accepting risk or losing tax benefits.
One London-based seller I worked with held both the business and the building in the same corporation. We needed the operating business and preferred a share deal to keep contracts and employees intact. The answer was a section 85 rollover to carve out the real estate into a new entity before closing, followed by a share sale of the cleansed operating company. That let the seller preserve their gains exemption, and we took the company we actually wanted without real estate risk. It took three months to execute properly. Rushing that process would have cost more than any interest saved by closing early.
Employment transitions that affect tax
If you buy assets and hire employees into a new corporation, you reset vacation accruals, termination liabilities, and in some cases benefits seniority. That clean break can be favorable in the long run, yet it triggers real costs in year one. From a tax vantage, accrued vacation pay on the seller’s balance sheet typically does not transfer if you structure correctly, which prevents you from inheriting a deduction you cannot use immediately. Plan for cash, forecast payroll taxes, and consider a small working capital reserve to absorb the first quarter’s bumps.
In a share purchase, inherited accrued liabilities carry forward, and deductions follow their own timing rules. Measure them. Push for a closing adjustment to reflect accurate accruals, not estimates that flatter earnings.
Environmental, equipment, and recapture
Manufacturing, auto, and certain trades around London carry environmental footprints. An asset purchase can reduce historical liability, but it does not eliminate environmental laws that tie obligations to land or equipment history. When you dispose of equipment later, remember that for tax purposes proceeds up to the original cost can trigger recapture if you have depreciated aggressively, which means income in that year. This is fine if you planned for it and need income to absorb losses or credits. It is not fine if it surprises you in a weak year. The purchase allocation you negotiate today sets up that future profile.
Pricing indemnities like real risk
Indemnities are not free. When the seller promises to cover pre-closing tax liabilities, ask yourself how collectible that promise is. If the seller plans to emigrate, wind up their holding company, or retire to a cottage and keep minimal liquidity, the indemnity has less bite. In those cases, you should either keep a holdback in trust or reduce price. I have seen buyers accept broad indemnities with no security and then eat a payroll tax assessment a year later because the indemnifier had nothing left for you to collect.
When buying the building makes sense
Many London businesses operate from owned real estate. If you have the balance sheet, acquiring the building along with the business can increase control and stabilize rent risk. From a tax perspective, putting real estate in a separate company or holding vehicle often makes sense. The operating business pays market rent, which is deductible to the opco and taxable in the real estate company. Capital cost allowance on the building can shelter some of that rent. Mortgage interest is deductible where used to earn income. Keep the structures clean, with a written lease. The rent number should withstand scrutiny, not match a round figure dreamed up at midnight before closing.
If you do not buy the building, negotiate a proper lease with renewal options, and make sure the leaseholds you fund are recognized in the purchase agreement. Leasehold improvements are depreciable. Get the landlord’s consent early. London landlords range from responsive families to slow-moving institutional owners. Beautiful tax planning collapses when a consent letter arrives the afternoon of closing with conditions you cannot meet.
Putting numbers to it, even if rough
A quick sketch for context helps avoid surprises. Suppose you are buying a local specialty food manufacturer for 2.2 million. In a share deal, the seller uses the lifetime capital gains exemption and pays low personal tax. You inherit the company with UCC balances of 400,000, minimal losses, and a clean HST record. Your tax shield in year one might be modest, say 35,000 to 50,000 in depreciation and amortization.
In an asset deal at the same 2.2 million, you allocate 200,000 to inventory, 300,000 to equipment, 100,000 to vehicles, 1.5 million to intangible assets including goodwill and a non-compete. Your first-year deductions could be higher, depending on class rates and the half-year rule, perhaps 80,000 to 120,000. The seller pays more tax if a chunk lands in business income, so they push price up or ask for a VTB to manage their reserve. You weigh the stronger deductions and lower legacy risk against the operational friction of reassigning contracts and rehiring staff.
Numbers like these do not decide the deal. They frame it.
A simple due diligence cadence that works
Use this as a compact sequence when you prepare to buy a business in London Ontario:
- Decide early whether you are leaning to shares or assets, then model after-tax cash flows both ways using realistic allocations and a sensitivity for HST treatment. Pull three years of corporate tax returns, HST filings, and payroll summaries, and tie them to financial statements month by month. Look for mismatches, late filings, or CRA letters that hint at risk. Test working capital definitions with real trial balances and agree on inclusions, explicitly handling HST net positions and tax installments. Audit employment status, WSIB history, and contractor agreements, then decide whether you will reset structures at closing or inherit them with indemnities and price protection. Draft the tax sections early: section 167 HST election if assets, VTB terms that enable a reserve for the seller, and clear treatment of earnouts with examples in the agreement.
Keep this list visible. It does not replace professional advice, but it prevents expensive omissions.
Where local context matters
London has a mix of family-run service businesses, healthcare clinics, manufacturing, logistics, and agri-food. Regulated clinics often favor share transactions due to licensing and college requirements. Manufacturing and trades skew toward assets because equipment, vehicles, and inventory form the core value, and buyers prefer fresh basis with lower legacy risk. If you plan to buy a business in London, talk to bankers who fund deals in this market. They know which structures speed credit approvals. A transaction that looks tax-efficient but confuses the credit committee will not get you to a closing table.
Strong business brokers London Ontario can also help you navigate personalities. Many sellers prioritize certainty and continuity as much as price. If your tax structure adds complexity, offering a generous transition period or keeping the founder as a paid advisor for six to twelve months can offset the discomfort.
The first 180 days after closing
Tax planning does not end at closing. The first two quarters determine how much of your plan becomes reality. Set up clean accounting from day one, with HST codes that match your industry specifics. File your first HST return early, even if minimal, to establish a pattern. Register or confirm payroll accounts under the new corporation if you bought assets, and reconcile source deductions weekly until you trust the system.
If you completed a section 167 HST election, store it with closing documents and ensure invoices from the seller around the closing date do not misapply tax. Lawyers hand you great closing binders. Great buyers revisit them before the first filing deadlines.
Review purchase price allocations before your first year-end and tie them to your capital asset continuity schedules. What looked tidy in a term sheet can drift during bookkeeping. Catching allocation errors in month two is easy. Fixing them after year-end is clumsy and, sometimes, costly.
The long arc: planning for your own exit
Many buyers forget they will become sellers. If your goal is to hold for five to seven years, build toward eligibility for the lifetime capital gains exemption. Keep the business as a qualified small business corporation by managing passive assets and ensuring active business tests are met. If you used a holding company, consider purification strategies well before a future sale. Do not carry large investment portfolios inside the operating company. Keep books clean enough that a future buyer’s accountant smiles on the first pass. Every hour you invest in clean systems returns to you as purchase price or as reduced friction when you decide to sell.
Common mistakes I still see, and how to avoid them
A handful of missteps repeat across deals:
- Rushing past HST and payroll diligence in a share purchase, then discovering assessments later with weak indemnities. Letting the seller dictate “share sale or no deal” without modeling your after-tax cash flows for both structures and pricing the difference. Neglecting purchase price allocations in asset deals, leaving too much in goodwill and missing amortization opportunities tied to identifiable intangibles. Mixing acquisition financing and operating cash in one account, creating use-of-funds headaches that complicate interest deductibility. Treating working capital targets as round numbers rather than negotiated definitions tied to specific accounts, including explicit treatment of HST positions.
None of these require brilliance to fix. They require attention and the willingness to slow down where it matters.

Final thoughts before you sign
Buying a business in London is personal. You are not buying an abstraction. You are buying early mornings at the shop, supplier calls, equipment that sometimes breaks, and a team you will come to know by first names. Tax is a frame, not the painting, but frames determine how the painting hangs, how long it lasts, and who admires it when you sell it on.
Use the flexibility Canadian tax rules give you. If a share deal fits, structure indemnities and diligence so https://liquidsunset.ca/business-valuation/ you sleep well and price for the tax shield you are giving up. If an asset deal fits, allocate carefully and take advantage of the fresh basis that rewards reinvestment. Keep your advisors close. The best accountants and lawyers in London will not drown you in jargon; they will translate risk into clear choices.
Above all, treat the seller as a partner through closing. Most are not trying to outsmart you on tax. They want a fair outcome and recognition for what they built. When the numbers line up and the structure reflects the reality of the business, both sides set themselves up for the kind of sunset that feels earned, not lucky.
