Owning a business means two jobs at once: paying tax on the profit and sending the CRA whatever you held back from employees. Slip up on either and interest and penalties follow, so an early estimate saves you trouble. It’s cheaper than a late fee.
The payroll remittance calculator shows what you owe the CRA on each pay run, both the employee and employer shares.
Which tool should an owner open first?
- Payroll Remittance Calculator
Estimate what an employer sends the CRA each pay period: source deductions plus the employer share.
- Corporate Tax Calculator
Estimate federal and provincial corporate income tax for a small business or a general corporation.
The corporate tax calculator applies the small business rate to eligible income and the general rate to the rest, using the province where your company is based.
Which other pages help?
Paying yourself a salary? You’ll want to check the payroll deductions calculator too. Taking dividends instead? You can compare with the dividend tax calculator for that. Sole proprietors will find the self-employed tax calculator a better fit.
We’re adding more business tools over time. Results are estimates, and your accountant should confirm the amounts you file.
When is the money due?
Remittances fall due on set dates that depend on your remitter type, and late payments carry a penalty that grows with the delay. Keep a record of every pay run so the amounts you send match your year-end slips.
Corporate tax is due within two months after the year end for most companies, or three months for some small ones, while the return itself is filed within six months. Setting money aside each month makes that bill easier to carry, and you won’t be scrambling when it lands.
Hiring for the first time? Price the new hire with the take-home pay calculator, the vacation pay calculator and the overtime pay calculator.
Frequently asked questions
How often do I have to remit payroll deductions?
It depends on the size of your average monthly withholding. Most small employers remit monthly, and larger ones remit more often.
What's the small business rate?
A lower federal and provincial rate on the first part of active business income earned by a Canadian-controlled private corporation.
Do I pay tax twice, as the company and personally?
Yes. The company pays tax on its profit, and you pay personal tax on any salary or dividends you take out.
Can I file with these results?
No. They help with planning and cash flow. Filing takes your full books.
