What is a shareholder loan and how is it taxed in Canada?

Two directions, two very different outcomes

A shareholder loan account tracks money flowing between an owner and the corporation. It runs in two directions:

• You lend to the company — you can withdraw that money later tax-free, because it is repayment of your own capital, not income.
• The company lends to you — this is where the tax traps live, because the CRA does not want owners drawing money as loans to sidestep the tax on salary and dividends.

Which direction the balance sits in at any moment determines whether there is a problem.

The one-year repayment rule

If you borrow from your corporation, you generally must repay it by the end of the corporation's next tax year. Repay within that window and there is no income inclusion. Miss it, and the full loan amount is added to your personal income in the year you received it, taxed at your marginal rate.

A critical trap: the repayment cannot be part of a series of loans and repayments. Repaying on day 364 and borrowing the same amount back on day 366 does not work; the CRA looks through the round trip. The repayment has to be genuine.

The prescribed-rate interest benefit

Even a loan repaid on time can create a smaller issue. If the corporation charges you no interest, or less than the CRA's prescribed rate, the difference is a taxable benefit added to your income for each year the loan is outstanding.

You avoid this by paying the corporation interest at least at the prescribed rate, by January 30 of the following year. The corporation then reports that interest as income. For modest, short-term balances the benefit is small, but for large or long-standing loans it adds up.

How owners get into trouble unintentionally

Most shareholder loan problems are not schemes, they are bookkeeping drift. An owner pays a personal expense from the business account, takes an advance against future dividends, or lets draws accumulate without declaring salary or dividends to clear them. The balance quietly grows into a debit shareholder loan.

At year-end the accountant either has to declare enough salary or dividends to clear it, creating a personal tax bill, or the balance stays and risks the income inclusion. Catching this before year-end is far cheaper than fixing it after.

Using the loan account deliberately

Used properly, the shareholder loan account is a useful tool. Money you have genuinely lent the company, including funds you invested at startup, can be repaid to you tax-free ahead of salary or dividends, which is often the most tax-efficient way to draw cash in a given year.

Tracking this accurately matters: many owners have a real credit balance they could draw tax-free but do not, because the account was never properly maintained. Clean books turn the loan account from a liability into a planning asset.
