Kanata Tech Compensation: How RSUs, Options and ESPP Are Actually Taxed

In most of Ottawa a pay stub is the whole story. In Kanata it frequently is not. The technology employers along the March Road corridor and through Kanata North pay a base salary and then layer equity on top, and for a senior engineer or a manager the equity can be the larger number. The trouble is that the three common forms of equity are taxed in three different ways, and the moment of tax is set by the plan, not by when you decide to sell. People who have never had to think past a T4 arrive at a return with a five-figure surprise built into it.

Restricted stock units are salary that happens to arrive as shares

An RSU is the simplest of the three and the one most often misunderstood. When the units vest, the fair market value of the shares that day is employment income. It goes on your T4 like any other pay, and the employer usually sells a slice of the vesting shares to cover the withholding, which is why a vest of a hundred shares often lands as roughly sixty in the account.

The part that trips people is what happens next. The value taxed at vesting becomes the cost base of the shares you keep. If you hold them and they rise, the further increase is a capital gain when you sell, and only that further increase. If they fall, you have a capital loss on the difference, but the income already taxed at vesting does not come back. A share held from a vest two years ago carries a cost base most people cannot state without digging out the vesting statement, and that number is the whole difference between calculating the gain correctly and guessing.

Stock options depend on whether the employer is a CCPC

Options are where the Kanata packet gets genuinely two-track, because the treatment turns on what kind of company granted them.

At a large public employer, a private-company subsidiary of a foreign parent, or any corporation that is not a Canadian-controlled private corporation, the taxable benefit on a non-qualified option arises when you exercise: the spread between the exercise price and the market value that day is employment income. Where the statutory conditions are met a one-half deduction can apply, which brings the effective rate on that spread closer to capital-gains treatment, but the income itself still lands at exercise whether or not you sell.

At a CCPC the timing moves. The benefit on the shares is generally deferred until you actually sell them rather than triggered at exercise, and a separate set of holding conditions can open the one-half deduction. Kanata has both kinds of employer within a few kilometres of each other, a global name and a venture-funded startup, so two neighbours on the same street can hold options that are taxed years apart. Knowing which regime your grant falls under is not a detail. It decides whether you owe tax in a year you received no cash.

An employee share purchase plan is a discount, and the discount is income

An ESPP lets you buy company shares through payroll, usually at a discount to market. That discount is the taxable event. On acquisition, the difference between what the shares were worth and what you paid is employment income, and because the entire point of the plan is a purchase price below market, the half-deduction that can soften an option grant is usually not available on the discount. Employer matching, where it exists, is a benefit in the same way.

Every purchase period creates its own tranche with its own cost base, and someone who has contributed to an ESPP for eight years is holding a stack of tranches each bought at a different price on a different day. When they finally sell, the gain has to be computed against those specific costs, not against a single average nobody wrote down. This is the single most common reconstruction job on a Kanata return, and it is entirely avoidable with a spreadsheet kept from the first purchase.

What to keep, starting now

The tax on all three forms is decided by records you either kept or did not. Keep the vesting statements for every RSU vest, with the share count and the fair market value used. Keep the exercise confirmations for options, with the exercise price and the market value that day, and know whether the grant is from a CCPC. Keep the purchase summaries for every ESPP period. None of this is exotic, and all of it is impossible to recreate accurately three years later when the brokerage has archived the account.

If your Kanata package is mostly equity, the return is not the moment to understand it. The moment is now, before another vest lands and adds a tranche to a pile nobody is tracking.
