2026 Personal Tax Filing Deadlines & What's New

Tax season is well underway, and 2026 brings several updates that every Canadian taxpayer should understand before filing. From the new digital services tax to expanded TFSA & FHSA contribution room, here's our quick rundown of what changes — and what doesn't.

If you take only one thing from this article: file by April 30, even if you can't pay the full balance. The 5% late-filing penalty plus 1%/month is far steeper than the interest on unpaid tax.

Key 2026 Filing Deadlines

• April 30, 2026 — Deadline for personal T1 returns and any balance owing.
• June 16, 2026 — Filing deadline if you or your spouse are self-employed (balance still due April 30).
• March 1, 2026 — Last day for 2025 RRSP contributions.
• December 31, 2026 — Deadline for charitable donations and TFSA contributions for the 2026 tax year.

What's New for 2026

1. TFSA Contribution Limit

The 2026 TFSA contribution limit has been confirmed at $7,000, indexed in line with inflation. If you've never contributed and were 18+ in 2009, your cumulative room is now $102,000.

2. RRSP Limit

The 2026 RRSP deduction limit is the lesser of 18% of your 2025 earned income or $32,490. Don't forget unused contribution room carries forward.

3. FHSA — Now in Year Three

The First Home Savings Account is hitting its stride. Eligible Canadians can contribute $8,000/year up to $40,000 lifetime. Unused room (up to $8K) carries forward — but only if you've opened the account.

4. Capital Gains Inclusion Rate

The proposed two-thirds inclusion rate above $250,000 has been deferred. For 2026, the 50% inclusion rate applies to all capital gains. We're watching for further announcements.

5. CPP Enhancement Phase 2

The second additional CPP contribution applies to income between $73,200 and the new YAMPE ceiling. Self-employed individuals pay both the employee and employer portions.

Common Errors We See

1. Forgetting to claim moving expenses (40km+ closer to a new job/school).
2. Missing medical expenses paid in the optimal 12-month window.
3. Not splitting eligible pension income between spouses.
4. Failing to report cryptocurrency dispositions (every trade is a taxable event).
5. Skipping T1135 disclosure when foreign assets exceed $100K cost.

What Happens If You File Late?

If you have a balance owing and miss April 30, expect:

• 5% penalty on the unpaid balance immediately.
• 1% per month for up to 12 months on the unpaid balance.
• If you've been late before, the penalties may double.
• Compound daily interest on top, currently around 10% annualized.
