CRA January Checklist: What Canadians Should Prepare Before 2026 Tax Season

TL;DR Summary

• Many Canadians wait until January or February to prepare CRA tax documents.
• Organising key slips before January reduces errors, delays and missed income.
• Side income and benefit statements are the most commonly overlooked items.

As December comes to a close, searches for “CRA January checklist” rise sharply across Canada.

That’s because many taxpayers only think about tax preparation once slips start arriving—often discovering too late that important information is missing or disorganised.

Preparing before January doesn’t mean filing early. It means avoiding stress when the 2026 tax season begins.

Why Preparing Before January Matters

January is one of the busiest periods for the CRA and financial institutions.

• Tax slips are released on different schedules
• CRA online accounts see heavy traffic
• Missing documents delay filing and refunds

Doing a short checklist in late December makes the rest of tax season smoother.

CRA January Checklist: What to Gather Now

1. Employment Income Slips (T4, T4A)

If you worked in 2025, you will likely receive a T4 from your employer.

Contract, freelance or other non-salary income may appear on a T4A—or not be reported at source at all.

Confirm who should issue slips and where they will be delivered.

2. Investment and Interest Slips (T5, T3)

Interest and dividend income from banks, credit unions and investment accounts is usually reported on T5 or T3 slips.

Small amounts are easy to forget but still taxable.

3. RRSP Contribution Records

RRSP contributions made during 2025—and in the first 60 days of 2026—can affect your return.

Gather contribution receipts now to avoid confusion later.

4. Government Benefit Statements

Some government payments may generate tax slips, including:

• Employment Insurance (EI)
• Canada Pension Plan (CPP)
• Old Age Security (OAS)

Checking your CRA or Service Canada account early helps ensure nothing is missed.

5. Side Income and Gig Work Records

Side income is one of the most common sources of CRA reassessments.

Income from freelancing, online selling or platform work often has no tax withheld.

Organising income and expense records now makes reporting easier later.

6. Deductible Expenses and Receipts

Work-related or business expenses require documentation.

Waiting until filing time often leads to forgotten or lost receipts.

7. CRA Online Account Access

Account access issues cause major delays every January.

Before the year ends, confirm you can:

• Log in successfully
• View tax slips and notices
• Receive CRA messages

Who Benefits Most From This Checklist

• Self-employed and side-income earners
• Canadians with multiple income sources
• Anyone who struggled last tax season
• People expecting refunds

Example: Preparing documents early reduces filing delays and the risk of CRA follow-up.

Common January Tax Prep Mistakes

• Assuming CRA already has all income details
• Forgetting small investment or side income
• Waiting for every slip before organising anything
• Ignoring CRA account access problems

How This Helps Your 2026 Tax Season

Early preparation doesn’t mean extra work—it means fewer surprises.

For many Canadians, a simple December checklist saves weeks of stress later.
