marginal tax notes 3541

Introduction to Marginal Tax Rate

  • The marginal tax rate influences investment decisions for clients.

  • Clients often wonder where to invest money: stocks, bonds, or mutual funds.

  • A significant factor in these decisions is the amount of tax payable, which relies heavily on the marginal tax rate.

Understanding Marginal Tax Rate

  • The marginal tax rate reflects the tax rate applied to the next dollar of income earned.

  • Investment type affects the marginal tax rate, potentially leading to different tax liabilities:

    • Interest income

    • Dividend income

    • Capital gains

Key Terminology

  • TC: Total marginal tax rate for federal and provincial levels.

  • TF: Marginal tax rate for federal income.

  • TP: Marginal tax rate for provincial income.

  • TSP: Provincial marginal surtax rates (only applicable in Ontario and PEI).

  • G: Gross-up dividend rate.

  • DTC: Dividend tax credit rate.

Tax Implications of Different Income Types

Ordinary Income (Interest Income)

  • The marginal tax rate on ordinary income is calculated as:

    • $TC = TF + TP$

  • If a surtax applies, it is calculated as:

    • $TC = TF + (1 + TSP) \times TP$

  • This tax implication means that the tax from dividends, as a type of interest income, is commonly assessed in this manner.

Capital Gains

  • Capital gains are taxed differently from ordinary income:

    • Only 50% of the capital gain is considered taxable income.

    • The general formula remains:

    • $TC = (0.5 \times TF) + (0.5 \times TP)$

    • If a surtax applies, it is included in the calculations as previously mentioned, multiplied by 50% of the respective rates.

Dividend Income Taxation

  • Tax treatment of dividends is more complicated due to the gross-up and credit factors:

    • Companies pay tax on profits before distributing dividends to shareholders.

    • The government allows a gross-up to reduce the tax burden on dividends, given that tax has already been paid at the corporate level:

    • Gross-up amount = dividend received × 1.38 (for example).

    • The applicable dividend tax credit is then applied:

    • This credit is based on the grossed-up amount of the dividend and varies between federal and provincial systems.

Surtaxes and Their Variances

  • Surtaxes in Ontario and PEI differ significantly:

    • In Ontario:

    1. Gross up dividend

    2. Calculate tax

    3. Apply tax credit

    4. Apply surtax afterwards.

    • In PEI:

    1. Gross up dividend

    2. Calculate tax

    3. Apply surtax

    4. Apply tax credit afterwards.

Practical Examples

Interest Income Example

  • Example scenario: Client Georgia with a federal tax rate of 20.5% and provincial rate of 9.15% with no surtax:

    • For $500 in interest income:

    • Tax calculation:

      • Combined Marginal Tax Rate = 20.5% + 9.15% = 29.65%.

      • Total Tax on Interest Income = $500 × 29.65% = $148.25.

      • After tax income = $500 - $148.25 = $351.75.

Capital Gains Example

  • Definition: Capital gain arises from the sale of investments (stocks, bonds, or property) at a profit.

  • Example: Selling a stock with:

    • Adjusted cost base = $4,500

    • Market value = $5,000 (gain $500)

    • Tax application:

    • Capital gain tax calculation for federal (20.5%) and provincial (9.15%) rates with no surtax:

      • Marginal Tax Rate = 0.5 × (20.5%) + 0.5 × (9.15%) = approximately 14.18%.

      • Tax on $500 capital gain = 14.18% × $500 = 74.125.

Considering Capital Losses

  • When reporting capital gains:

    • Capital losses can offset capital gains:

    • If a capital gain of $500 is achieved but a capital loss of $100 is reported:

      • Net gain = $500 - $100 = $400.

      • Tax calculation on net gain.

  • Furthermore, capital losses can be carried forward indefinitely for future offsets or back to previous tax years, up to three years.
