Introduction

A startup exit — whether a trade sale, an acqui-hire, or a secondary share transaction — produces a liquidity event that most founders have been working toward for years. The months immediately following the exit are when the financial decisions made will shape the next decade. This article covers the tax and wealth management priorities that should be on the founder's radar from day one post-close.

The Tax Picture in the Exit Year

As discussed in Articles 103 and 127, the tax treatment of exit proceeds depends on the structure:

Share sale capital gain: The primary proceeds from a qualifying share sale are a capital gain — eligible for the LCGE on the first ~$1.25 million and taxed at the capital gains inclusion rate (subject to the inclusion rate changes discussed in Article 170) on the remainder.

Retention bonuses and employment income: Any portion of the consideration structured as a retention bonus or consulting fee is employment or business income — taxed at full personal marginal rates.

Earnout payments: Taxed in the year received or determinable, at the applicable rate for the character of the income (capital or employment, depending on the arrangement).

Priority 1: RRSP Contribution in the Exit Year

The exit year is almost certainly the year of peak personal income — the capital gain plus the year's normal income (salary, dividends) produces the highest marginal rate the founder will face. Any RRSP room accumulated from prior years of salary income should be exhausted in the exit year — the deduction is most valuable at the highest marginal rate.

A founder with $60,000 of accumulated RRSP room who contributes in the exit year at a ~53% marginal rate saves approximately $31,800 in personal tax. The same contribution in a lower-income year saves less.

Priority 2: Holdco as a Post-Exit Investment Vehicle

Where exit proceeds arrived personally (and were not held through a holdco pre-exit), the founder has a large personal investment portfolio. Going forward, whether to invest personally or to re-incorporate through a new holdco depends on the amount and the planned investment horizon.

For a founder with $3 million of after-tax proceeds who intends to invest passively for fifteen or more years, a new holding company may warrant consideration — even though the after-tax amount has already been received personally — for the estate planning and OAS clawback management benefits discussed in earlier articles.

Priority 3: Diversification Under Tax Awareness

Startup founders often hold highly concentrated positions at exit — particularly where some consideration is paid in the acquirer's shares. Diversifying away from the acquirer's stock creates capital gains events. A financial advisor and CPA working together can sequence the diversification over time — realising gains in years where other income is lower — rather than triggering a large gain immediately in the already-high exit year.

Priority 4: The CPP Gap

Many startup founders paid themselves minimal salary for years — bootstrapping compensation in favour of equity. As discussed in Article 169 (in the contractor context), low salary means low CPP contributions and a lower CPP retirement benefit.

Post-exit, if the founder is not yet of CPP receipt age, they cannot retroactively fill the CPP gap. The retirement income plan must account for the reduced CPP floor.

Priority 5: The Next Chapter's Tax Structure

Many successful founders launch another company, take on advisory roles, or join boards — generating income that requires a new corporate structure or an update to an existing one. The holdco may serve as the vehicle through which advisory fees or board compensation flows. Setting up the structure before the income begins is more efficient than restructuring after the fact.

When to Speak With a CPA

The first CPA conversation post-exit should happen within 30 days of closing — not after the calendar year ends. The exit-year decisions (RRSP, instalment adjustments, holdco planning) are time-sensitive.
