This blog outlines all the major tax deadlines in 2025 to help Canadians stay prepared and avoid last-minute stress.

Filing taxes is not just about following the law. It is also about protecting your finances. Filing late can result in costly penalties and missed opportunities to claim benefits. Whether you are employed, self-employed, or own a business, planning ahead helps you manage your money better. This blog offers a complete guide to the key dates and requirements for 2025.

Key Tax Deadlines for Individuals in 2025

February 24, 2025: NETFILE Opens

The Canada Revenue Agency (CRA) will open its NETFILE service for the 2024 tax year on February 24, 2025. This means you can begin submitting your income tax return online. Filing early gives you more time to plan and usually leads to faster refunds. If you are expecting a refund, the earlier you file, the sooner you can receive your money, which could help with early-year expenses or investments.

April 30, 2025: Filing and Payment Deadline

April 30, 2025, is the deadline to both file your personal income tax return and pay any taxes owed. This deadline applies to most Canadians, including employees and retirees. If you do not file or pay by this date, the CRA may charge late-filing penalties and daily interest on the balance owed. Filing on time also ensures that any benefits you receive, like the Canada Child Benefit or GST/HST credit, continue without interruption.

Deadlines for Self-Employed Individuals

Self-employed individuals have slightly different rules.

June 15, 2025: Filing Deadline for Self-Employed

If you or your spouse or common-law partner is self-employed, you have until June 15, 2025, to file your tax return. However, since June 15 falls on a Sunday in 2025, the CRA will likely accept returns filed by Monday, June 16. It is important to plan accordingly, as filing late could affect your access to benefits or even lead to audits if taxes are not paid accurately.

April 30, 2025: Payment Deadline Still Applies

Even though you can file later, the deadline to pay any taxes you owe is still April 30, 2025. If you pay after this date, the CRA will start charging interest on the unpaid balance. Keeping track of your income and expenses throughout the year can make it easier to calculate what you owe and avoid surprises.

RRSP Contribution Deadline

March 1, 2025: Final Day for RRSP Contributions

To reduce your taxable income for the 2024 tax year, you must make contributions to your Registered Retirement Savings Plan (RRSP) by March 1, 2025. Contributions made after this date will apply to the 2025 tax year. RRSPs are a valuable tool for retirement planning and can significantly lower your taxable income, especially for those in higher tax brackets.

Instalment Deadlines for Individuals

If you owed more than $3,000 in taxes in any of the past two years ($1,800 for residents of Quebec), you may be required to pay your taxes in instalments.

Instalment Due Dates in 2025:

• March 15, 2025
• June 15, 2025
• September 15, 2025
• December 15, 2025

Make sure you pay these amounts on time. If not, the CRA may charge interest on the missed payments. Setting up reminders or automatic payments can help avoid missed deadlines.

T4 and T5 Slips: Employer and Payer Deadlines

If you are an employer or pay dividends or interest, you must file information slips.

February 28, 2025: Deadline for T4 and T5 Slips

All T4 (employment income) and T5 (investment income) slips must be submitted to the CRA and provided to employees or recipients by February 28, 2025. These slips are necessary for individuals to file their personal income tax returns and must be accurate to prevent filing errors or audits.

Corporate Tax Deadlines

Corporate tax deadlines depend on the company’s fiscal year-end.

Filing Corporate Tax Returns (T2)

A T2 return must be filed no later than six months after the end of your corporation’s fiscal year. For example, if your fiscal year ends on December 31, 2024, the filing deadline is June 30, 2025.

Payment Deadlines for Corporations

Taxes owed are due either two or three months after the fiscal year-end, depending on whether the corporation qualifies as a Canadian-Controlled Private Corporation (CCPC). Generally, CCPCs with small business deductions have three months to pay.

It is wise to work with an accountant or tax professional to avoid underestimating your tax obligations. Many businesses face audits or penalties due to misfiled returns or missing documents.

Penalties for Missing Deadlines

Failing to file or pay your taxes on time can result in serious financial consequences.

Late-Filing Penalty

The CRA charges a penalty of 5% of the unpaid taxes if your return is late, plus 1% of the balance for each full month the return is late, up to 12 months.

Interest Charges

Interest starts the day after your due date. This applies to unpaid taxes, late instalments, and other balances owed.

Impact on Benefits

Failing to file on time can delay the processing of government benefits such as the GST/HST credit, Canada Child Benefit, and other income-tested programs.

How to File Your Taxes

You have several options when it comes to filing your return:

1. NETFILE

NETFILE is a CRA-approved online filing system. You can use certified software to file your return directly. This method is the fastest and most convenient for most individuals.

2. EFILE

This method allows authorized tax preparers to file taxes on behalf of individuals. It is a good option if you are working with an accountant or a tax service.

3. Paper Filing

You can still file a paper return by mailing it to the CRA. This method takes longer to process and increases the chances of delays, especially close to the filing deadline.

Preparing for Tax Season

Start early to make filing your return easier.

Collect Your Documents

Gather your T4s, T5s, RRSP contribution slips, receipts, and other supporting documents. Keeping them organized will reduce the time it takes to file.

Set Reminders

Mark important deadlines in your calendar so you do not miss them. Using digital calendars or reminder apps can keep you on track.

Use CRA My Account

This online tool gives you access to your previous tax returns, RRSP limits, instalment reminders, and more. It also allows you to track refunds and submit documents electronically.

Hire a Tax Professional

If your tax situation is complex, a CPA or tax expert can help ensure you file correctly and claim all your deductions.

Business Owners: What You Need to Know

If you own a business, staying compliant involves more than just filing a T2 return.

GST/HST Filing Deadlines

Your filing frequency (monthly, quarterly, or annually) depends on your sales volume and CRA requirements. Be sure to know your due dates. Missing a GST/HST payment can lead to serious fines and penalties.

Payroll Remittances

If you have employees, you must remit payroll deductions (income tax, EI, and CPP) on time. The due date is usually the 15th of the following month. Employers who fail to remit on time can face penalties and interest charges.

Year-End Preparation

Close your books, prepare your financial statements, and file the necessary slips and returns promptly to avoid fines. Business owners should also review potential deductions and credits that may lower their tax burden.

Avoiding Tax Scams

Tax season often comes with a rise in scams. Protect yourself by knowing what CRA will and will not do.

CRA Will Never:

• Ask for payment by gift cards or cryptocurrency.
• Send threats by phone or email.
• Ask for personal details via text messages.

If you receive a suspicious message, contact CRA directly using the number listed on their official website.
