RSUs in Canada 2025: How They're Taxed

Updated for 2025 · Vesting tax treatment · T4 reporting · Sell-to-cover

Restricted Stock Units (RSUs) are a form of equity compensation where your employer promises to deliver shares (or the cash equivalent) to you at a future date, typically upon meeting a vesting schedule. RSUs have become the dominant form of equity compensation at Canadian public and large private companies. Unlike stock options, RSUs always have value when they vest — but they're taxed as employment income at full marginal rates with no 50% deduction.

How RSUs Work

An RSU grant is a promise to deliver shares over time. Vesting typically occurs on a schedule such as:

• Annual cliff vesting: 25% per year over 4 years
• Monthly/quarterly vesting: proportional vesting each period over 3-4 years
• Performance-based vesting: vesting tied to company or individual performance metrics

Until vesting, RSUs are just a promise — you own nothing. On the vest date, shares are actually delivered to you, and that is the tax event.

Tax Treatment at Vesting: Full Employment Income

When RSUs vest, the full fair market value (FMV) of the shares on the vesting date is employment income. There is no 50% deduction available for RSUs (unlike qualifying stock options). You are taxed at your full marginal rate on the entire vested value.

No 50% Deduction Available

This is the most important difference between RSUs and stock options. Stock options that meet the qualifying conditions can use the 50% deduction to effectively halve the tax. RSUs provide no such deduction — the full vested value is 100% employment income.

Tax Withholding: Sell-to-Cover

Because RSU vesting creates an immediate tax liability, employers must withhold income tax. Most employers use a "sell-to-cover" method:

1. RSUs vest; say 500 shares at $40 each = $20,000 employment income
2. Employer calculates tax due (e.g., 43% = $8,600)
3. Employer sells 215 shares ($8,600 / $40) on your behalf
4. You receive the remaining 285 shares in your brokerage account
5. The $8,600 is remitted as withholding to CRA and credited to your tax account

Some employers allow cash payment of the tax withholding in lieu of selling shares (pay-to-retain). This is beneficial if you believe in the stock's future appreciation.

T4 Reporting

Your employer reports RSU income on your T4:

• Box 14 — Total employment income including the RSU vesting amount
• Box 38 — Security options benefit (includes RSU income)

Box 38 is informational — the income is already included in Box 14. There is no offsetting deduction in Box 39 for RSUs.

After Vesting: Capital Gains Treatment

After vesting, your cost base for the shares is the FMV on the vesting date (the amount reported as employment income). Any gain or loss after vesting is a capital gain or loss when you sell:

• Shares appreciate after vesting: capital gain = (sale price - vesting FMV) x shares; only 50% included in income
• Shares decline after vesting: capital loss = (vesting FMV - sale price) x shares; offsets capital gains

If you immediately sell on the vest date (same-day sale), there is typically no capital gain or loss (the sale price equals the cost base).

Cross-Border RSU Taxation Complexity

If you worked in multiple countries during your RSU vesting period, the employment income must be allocated between jurisdictions. For example, if RSUs were granted when you worked in the U.S. and vest after you've moved to Canada, only the portion earned in Canada is taxable in Canada. The portion earned while a U.S. resident may be taxable in the U.S. This is a complex area requiring professional tax advice.

RSU Planning Strategies

• RRSP contributions — If you have available RRSP room, contributing in the same year RSUs vest can offset some employment income
• Timing of additional income — If possible, defer other discretionary income to years where RSU vesting is lower
• Hold or sell decision — From a tax perspective, selling on vest and buying back in a TFSA or RRSP is often more efficient than holding concentrated stock
• Income splitting — If your spouse has lower income and you give them shares (prescribed rate loan strategy), future capital gains may be taxed in their hands; complex rules apply

RSUs vs Stock Options: Key Differences

Frequently Asked Questions

Are RSU dividends taxable?

Before vesting, RSUs typically don't pay dividends (you don't own shares yet). However, some RSU plans include dividend equivalents that are paid on vest alongside the shares. These dividend equivalents are treated as employment income, not eligible dividends.

What happens to unvested RSUs if I leave my employer?

Unvested RSUs are typically forfeited upon voluntary resignation. Some RSU plans accelerate vesting or provide a prorated amount upon layoff, retirement, or death. Check your RSU grant agreement and equity compensation plan document.

My employer is a foreign company — are RSU rules different?

Canadian employees of foreign-incorporated companies follow the same Canadian tax rules for RSUs — the vested value is employment income. However, the foreign employer may also withhold tax in their jurisdiction. A tax professional familiar with cross-border employment situations can help you avoid double taxation through treaty relief.
