Last-Minute Tax Filing: What You Must Do Before Submitting
Filing taxes close to the deadline is very common for many Canadians. Whether due to busy schedules, missing paperwork, or simple procrastination, thousands of individuals and business owners complete their tax returns in the final days before submission.
However, last minute tax filing can lead to costly mistakes if the return is not carefully reviewed. Errors such as incorrect income reporting, missed deductions, or self-employment miscalculations can trigger penalties or even CRA audits.
Before you submit your tax return, there are several important checks you should complete to ensure everything is accurate and optimized.
Income Verification Errors
One of the most common issues during last minute tax filing is incorrect income reporting. Many taxpayers forget to verify that all income slips have been included.
Common slips to review include:
T4 employment income
T5 investment income
T4A contract income
T4A(OAS) or pension income
Rental or business income
If any income slips are missing or incorrect, it may result in a reassessment by the Canada Revenue Agency.
You should compare your return with the slips available in your CRA My Account to ensure that every source of income has been reported accurately.
Missed Deductions
When filing taxes quickly, taxpayers often forget valuable deductions that can significantly reduce the tax bill.
Some commonly missed deductions include:
Home office expenses for remote workers
Medical expenses
Childcare expenses
RRSP contributions
Student loan interest
For business owners or self-employed professionals, the list of deductions can be even longer.
Properly reviewing deductions can potentially save hundreds or even thousands of dollars. A professional review ensures these deductions are properly claimed and documented.
Self Employed Tax Pitfalls
Self-employed individuals face additional challenges during tax filing.
Common mistakes include:
Underreporting income
Incorrect expense classification
Forgetting GST/HST reporting
Claiming non eligible business expenses
The CRA pays close attention to self-employed tax returns, especially those showing unusually high deductions or inconsistent income patterns.
If you are self-employed, a careful review of revenue and expenses is essential before submitting your tax return.
When to File a Tax Extension
Sometimes the best option is not to rush your tax return.
If you are missing documents or unsure about deductions, filing an extension may be a better strategy.
In Canada, individuals must typically file their returns by April 30. However, self-employed individuals have until June 15 to file, though any taxes owed must still be paid by April 30.
