How is unbilled work in progress treated when selling a professional practice?

The firm's books, and its tax returns, still assumed an election the Income Tax Act stopped offering designated professionals years earlier.

Short answer

Since 2017 there is no election to defer it. Income Tax Act s.34, the old billed-basis election that let six designated professions leave their work in progress out of income until billed, was repealed, and s.10(4)(a) now requires WIP to be valued at the amount reasonably expected to become receivable — so a firm still filing on a billed basis is simply following a rule that no longer exists.

The rule

Section 34 now reads, in full: “[Repealed, 2017, c. 33, s. 7]” — the old billed-basis election is gone from the consolidated statute. In its place, s.10(4)(a) fixes the value: the fair market value of property that is “work in progress at the end of a taxation year of a business that is a profession means the amount that can reasonably be expected to become receivable in respect thereof after the end of the year.”

When this changes

This only ever reached the six designated professions the old election covered — accountants, dentists, lawyers, physicians, chiropractors and veterinarians. A trades or ordinary service business carrying unbilled revenue was never inside s.34 to begin with, so its WIP question is a different one entirely. Where a firm’s post-repeal returns have understated income because they never adjusted, the fix on a sale is refiling before closing, with the vendors carrying responsibility for the correction rather than leaving it inside the buyer’s newly acquired history.

The Canadian benchmark

What do businesses like this one actually sell for?

Canadian small-business transaction data is not published anywhere, so most valuations in this country quote an American benchmark. The Deavo–Treadstone Acquisition Index is a daily record of Canadian listings built to replace that: asking-price distributions by province and city are published now, and days on market, departure rates and asking-to-sale spreads follow as the series lengthens.
