“Optimizing Tax Efficiency: Incorporation vs. Sole Proprietorship for Robinson Inc. in 2022”

QUESTION

John Robinson is the sole owner of Robinson Inc in 2022. Robinson Inc. operates in a province with a provincial corporate tax rate of 6% for income eligible for the small business deduction, and 11% for all other income.

Robinson Inc. earned taxable income of $200,000 during 2022, all of which is active business income. John Robinson’s marginal tax rate (federal and provincial combined) is 45%. He withdraws all of his corporation’s after-tax income as a dividend each year.

John Robinson is considering whether it would be more beneficial if he were to operate his business as a sole proprietorship as opposed to a corporation.

Assume that the dividend tax credit is always equal to the dividend gross-up amount. Other than the dividend tax credit, you may ignore all other personal tax credits for this question.

REQUIRED

1. Assuming that Robinson Inc’s taxable income is NOT eligible for the Small Business Deduction, calculate the total tax cost or total tax savings from incorporating.
2. Repeat question a), but assume that Robinson Inc’s taxable income is eligible for the Small Business Deduction.
3. Assuming that Robinson Inc. is eligible for the Small Business Deduction, what would the dividend Gross-up Rate % need to be in order to achieve full integration in that province (i.e. no tax cost or tax savings)? Assume the dividend tax credit would be equal to the gross-up.

ANSWER

In the realm of tax planning, choosing the most advantageous structure for a business can significantly impact an individual’s overall tax liability. John Robinson, the sole owner of Robinson Inc., is contemplating whether operating his business as a sole proprietorship or a corporation would be more beneficial from a tax perspective. To make this decision, it’s crucial to analyze the tax implications under different scenarios.

Taxation of Robinson Inc.’s Income (Not Eligible for Small Business Deduction)

Robinson Inc. earned $200,000 in taxable income in 2022, and the provincial corporate tax rate for income not eligible for the small business deduction is 11%. Additionally, John Robinson’s marginal tax rate for personal income, which includes dividends from his corporation, is 45%.

If Robinson Inc. remains a corporation, it will be subject to a corporate tax of 11% on its $200,000 income, resulting in a tax liability of $22,000. When John receives dividends from the corporation, he will face a personal tax liability at his marginal rate of 45%. Therefore, his after-tax income from the corporation would be:

$200,000 (pre-tax income) – $22,000 (corporate tax) = $178,000

Then, John would pay personal taxes on this amount:

$178,000 * 45% = $80,100

So, the total tax cost of operating as a corporation, in this case, would be:

$22,000 (corporate tax) + $80,100 (personal tax on dividends) = $102,100

Taxation of Robinson Inc.’s Income (Eligible for Small Business Deduction)

If Robinson Inc.’s income is eligible for the Small Business Deduction, the provincial corporate tax rate is reduced to 6%. Consequently, the corporate tax liability would be:

$200,000 (pre-tax income) * 6% = $12,000

John’s personal tax on dividends would remain the same at $80,100, as calculated in the previous scenario.

Therefore, the total tax cost of operating as a corporation, assuming eligibility for the Small Business Deduction, would be:

$12,000 (corporate tax) + $80,100 (personal tax on dividends) = $92,100

Achieving Full Integration with the Small Business Deduction

Full integration occurs when the combined corporate and personal taxes equal the tax that would be paid if the income were earned directly by John. To achieve this, we need to determine the dividend Gross-up Rate % that would result in no tax cost or savings.

Let G represent the Gross-up Rate %. The corporate tax on the grossed-up dividend income (1 + G) would be 6%, and the personal tax on this income would be 45%. Setting them equal to John’s personal tax rate:

6% * (1 + G) = 45%

Solving for G:

(1 + G) = 45% / 6% (1 + G) = 7.5

G = 7.5 – 1 G = 6.5%

So, to achieve full integration in this province with the Small Business Deduction, the dividend Gross-up Rate % would need to be 6.5%.

In conclusion, the decision to operate as a sole proprietorship or a corporation depends on Robinson Inc.’s eligibility for the Small Business Deduction and the desired level of tax integration. Without the deduction, incorporating results in a higher total tax cost. With the deduction, incorporating is more tax-efficient. To achieve full integration with the deduction, a dividend Gross-up Rate % of 6.5% is required. Tax planning should consider these factors to optimize John Robinson’s tax strategy.
