Key takeaways
  • A working capital adjustment is a contract term that moves the headline price up or down after closing, depending on how the business's day-to-day position compares with an agreed target.
  • How the price is split among assets, inventory and goodwill changes the tax result for both sides, so the adjustment and the allocation should be read together.
  • The details are set by the agreement you sign, so the definitions and the accounting method matter as much as the target number.

The price on the first page of a letter of intent is rarely the amount that changes hands. Many Ontario business sales include a working capital adjustment, which lets the price move up or down once the real numbers at closing are known. If you are buying, it protects you from paying full price for a business that has been drained. If you are selling, it can reduce your proceeds if the business is short on the closing date.

This article explains in plain words how a target and a closing adjustment work, what tends to be argued about, and how the adjustment connects to tax rules on price allocation and sales tax. The exact mechanics always come from the agreement, so use this as a guide to the questions to ask.

What a working capital adjustment is

Working capital is, roughly, the money a business needs to run from day to day. It usually means the short-term items the business is owed or holds, such as receivables and inventory, less the short-term items it owes, such as supplier bills. The buyer expects to receive a business with a normal level of these items, so the parties agree on a target figure.

At closing, the actual working capital is measured against that target. If it is higher than the target, the price goes up. If it is lower, the price goes down. The adjustment is a contract term; it is not a tax rule or a legal requirement, so it only exists if your agreement includes it.

How the target and the closing adjustment work

Most agreements follow the same steps. The details, including timing and who prepares what, vary from deal to deal.

The target matters most. A target set too high means the seller pays through a price reduction even when the business is running normally. A target set too low lets the buyer take over a business that needs more cash than expected. Seasonal businesses need particular care, because working capital on one closing date can look very different from another.

What goes into the calculation

Disputes usually come from definitions rather than arithmetic. The agreement should say exactly which accounts are in and which are out, and which accounting policies apply.

ItemWhy it is argued about
Accounts receivableWhether old or doubtful accounts count, and at what value
InventoryHow it is counted and valued, and whether slow-moving stock is included
Accounts payable and accrualsWhether unpaid bills and year-end accruals are fully captured
Cash and debtOften handled separately, so check whether they sit inside or outside the working capital figure

For tax purposes, the price for goods and property is looked at in parts, and the part reasonably attributable to a property is that property's proceeds for the seller and its cost for the buyer. So a price adjustment tied to inventory or receivables is not just a number. It can feed into how each side reports the sale.

How it connects to tax and price allocation

The tax effect depends on whether the deal is a share sale or an asset sale. In a share purchase, the buyer buys the corporation itself, and the change in share ownership does not change the tax values of the corporation's assets. In an asset purchase, the buyer records each asset at its allocated cost.

If the sale agreement sets reasonable prices for individual assets, those prices are used. If not, the price is allocated to each asset at fair market value, then to inventory, and the remaining balance to goodwill. The buyer's allocation should match what the seller reported. A later working capital adjustment can change those numbers, so the agreement should say how an adjustment is allocated.

Allocation changes real results. In an asset purchase, fixed assets go into their capital cost allowance classes, goodwill goes into Class 14.1, and inventory is treated as goods for resale in cost of goods sold. On the seller's side, allocating more of the price to depreciable equipment can raise the seller's tax, because recaptured depreciation is included in income in full.

What to do next

Before you sign, work through the adjustment clause as carefully as the headline price. A small difference in definitions can move the final amount by more than a modest change to the price itself.

Frequently asked questions

Is a working capital adjustment required when buying a business in Ontario?

No. It is a term the parties negotiate into their agreement. If the agreement does not include one, the price generally stays as written, subject to whatever other price terms the parties agreed.

Does the adjustment apply to both share and asset sales?

It can be used in either. The tax treatment differs, though. In a share purchase the tax values of the corporation's assets do not change, while in an asset purchase the buyer records each asset at its allocated cost.

Can the adjustment change how the price is allocated?

It can. If the agreement does not set reasonable prices for individual assets, the price is allocated to assets at fair market value, then to inventory, with the balance to goodwill. The agreement should say how any later adjustment is spread across those categories.

What if the buyer and seller disagree on the closing figures?

Most agreements set a review period and a process, often involving an independent accountant. What yours says controls, so it is worth reading that process carefully and having a lawyer confirm it before you sign.
