Understanding Quarterly Tax Payments for Self-Employed Individuals

1. Know if Quarterly Payments Apply to You

If you're self-employed in Canada and your net tax owing for the year is more than $3,000, the CRA expects you to make quarterly installments the following year.

This includes:

• Sole proprietors

• Freelancers and gig workers

• Independent contractors

• Anyone earning business or professional income not taxed at source

  
  

If your tax owed last year was under that threshold, you’re off the hook for now—but keep an eye on your income. You may cross the line.

2. Calculate Your Net Income

Start with gross self-employment income: all money earned from clients or projects.

Then subtract allowable business expenses:

• Office supplies

• Software subscriptions

• Travel and vehicle costs

• Home office portion of rent, internet, etc.

  
  

Your total earnings minus these deductions = net business income.

Tip: Keep monthly bookkeeping up to date so you're not guessing each quarter.

3. Estimate Your Annual Tax Owed

Once you have an annualized estimate of your net income, you can roughly calculate how much tax you’ll owe using:

• Federal tax brackets

• Provincial/territorial tax rates

• CPP contributions (yes, self-employed folks pay both employer and employee portions)

  
  

Use a self-employment tax calculator or online estimator for a shortcut. Alternatively, base it on last year’s return—if your income hasn’t changed drastically.

Note: In Canada, self-employed individuals must contribute ~11.9% of net income up to a max CPP threshold (adjusted yearly).

4. Divide by Four for Quarterly Payments

Once you have a rough estimate of your annual tax (including CPP), divide it by four. That’s your quarterly payment.

Due dates for CRA installments:

• March 15

• June 15

• September 15

• December 15

  
  

Set reminders. Late or insufficient payments may trigger installment interest.

5. Adjust Throughout the Year

Income fluctuating? That’s normal. Just recalculate each quarter if needed.

For example:

• Q1 earnings were low → pay less

• Q2 and Q3 boomed → recalculate to avoid underpaying

  
  

You’re allowed to adjust as long as you cover 90% of the tax you actually owe for the year, or 100% of the previous year’s tax. Whichever is lower.

6. How to Pay Quarterly Taxes

Make payments online through:

• CRA My Account

• Online banking (as “CRA Tax Instalment”)

• Pre-authorized debit

• Mail (cheque, with remittance voucher)

  
  

If you’re consistently under- or overpaying, talk to a tax professional. One mistake repeated four times adds up fast.

7. Keep These Documents Handy

You’ll want to hold on to:

• Invoices

• Receipts for deductions

• Bank statements

• Past returns

  
  

They’ll help you back up your estimates—and prepare your final return.

Accurate tax payments are crucial for maintaining financial health. Paying the right amount ensures you avoid penalties and interest charges. It also helps you manage your cash flow effectively.

When you pay your taxes on time, you can focus on growing your business instead of worrying about unexpected tax bills.
