How Canadian Account Types Affect Compound Growth

TFSA (Tax-Free Savings Account): Contributions are made with after-tax dollars, but all investment growth — interest, dividends, and capital gains — is completely tax-free. Withdrawals are tax-free and don't count as income, so they don't trigger OAS clawback or affect other benefits.

RRSP (Registered Retirement Savings Plan): Contributions are tax-deductible, reducing your taxable income in the year you contribute. Investments grow tax-deferred. However, all withdrawals are taxed as ordinary income, and they count toward the OAS clawback threshold.

Non-Registered Account: No contribution limits or tax sheltering. Investment income is taxed annually — interest at your full marginal rate, eligible dividends with a gross-up and credit, and capital gains at a 50% inclusion rate. This annual tax drag reduces the amount that compounds.
