The monthly figure is the same monthly amount that would carry a mortgage of about $510,000 at 5% over 25 years.

A snapshot of one year, using your figures and published Ontario tax rates. It is not a forecast; no future years are projected.

1. The Structure Leak

Not leaking

Your income is being kept in a corporation rather than earned personally. This one is closed.

Small-business rate in Ontario11.20%
Top personal rate if earned personally53.53%

Incorporating defers tax rather than erasing it. The second level arrives when money comes out to you, which is the next leak.

2. The Access Leak

$27,405/year

Money you moved out of the company and then did not spend was taxed on the way.

Drawn out and left unspent$30,000 after tax
Taken asdividends, taxed at 47.74%
Company had to release$57,405 to deliver it
Tax paid to move it, this year$27,405

Tax on money you actually needed to live on is not counted here. That is simply the cost of living. This is only what it cost to move out money that then sat unspent.

3. The Growth Leak

$1,219/year

Money the company invests is taxed at a much higher rate than money it earns.

Your company earned from investments$10,000
Corporate tax at 50.17%$4,573
Comes back when dividends are paid−$3,354
Tax that does not come back$1,219
Cost this year$1,219

Some of that tax is refunded, but only once taxable dividends are actually paid out. Until then it sits with CRA rather than working for you.

4. The Inflation Leak

$7,350/year

Money sitting in cash keeps its balance but loses what it can buy.

Held in cash or near-cash$350,000
Inflation applied2.10%
Purchasing power lost this year$7,350

No money leaves the account. The number on the statement stays the same; what it buys does not.

Where figures weren't available

Replacing these with your real numbers will change the result. That can be done on the call.

What this is. Arithmetic applied to the figures you provided, using published federal and Ontario tax rates currently in effect.

What this is not. It is not tax, legal, accounting or financial advice, and it is not a recommendation to do, or stop doing, anything. It does not project future years or model any product. Personal tax is applied at a single marginal rate rather than through full graduated brackets, so it approximates the top slice of income only. A corporation whose fiscal year spans a rate change will have a blended rate that differs from the figures shown.

Before acting on anything here, speak with your own accountant, tax specialist and lawyer, who can see your complete situation.
