How to Handle RSUs in Canada
Canadian software engineers are being advised on how to manage their Restricted Stock Units (RSUs) to avoid tax pitfalls. Key strategies include understanding that RSUs are taxed as employment income upon vesting, not at grant. Experts suggest selling a portion of vested shares immediately to cover the tax bill and to diversify away from a heavy concentration in employer stock.
The fair market value of RSUs is added to your T4 slip as employment income in the year they vest, subject to both federal and provincial taxes, plus CPP and EI contributions. Any subsequent growth in share value is treated as a capital gain when you sell, with 50% of that gain being taxable. While employers often automatically sell a portion of vested shares to remit taxes—a "sell to cover" approach—this withholding may not align with your actual marginal tax rate. This can result in additional taxes owed when you file your return, especially for high-income earners whose marginal rate exceeds the basic withholding rate. A common Canadian strategy involves selling vested shares and immediately contributing the proceeds to a Registered Retirement Savings Plan (RRSP). This contribution generates a tax deduction that can offset the large income inclusion from the vested RSUs, effectively reducing your overall tax bill for that year. Most RSU plans at major tech companies are structured to avoid being classified as a Salary Deferral Arrangement (SDA) by the Canada Revenue Agency. If a plan were to trigger SDA rules, the RSUs could become taxable when granted rather than when vested, creating a significant and early tax headache. The market value of the shares on the day they vest establishes your Adjusted Cost Base (ACB) for those shares. This ACB is the figure you use to calculate capital gains or losses when you eventually sell the stock. Unlike in the U.S., there is no tax advantage in Canada for holding onto vested RSU shares for a longer period before selling. The capital gains inclusion rate remains the same, making the argument for immediate selling and diversification more compelling to mitigate single-stock risk.
