What Box 14 means
Box 14 shows your total employment income for the calendar year: gross salary plus bonuses, commissions, vacation pay, taxable benefits (company car, premiums, etc.), retroactive pay adjustments, and most taxable employer payments. It is gross — before CPP, EI, income tax or any other deductions are withheld.
The CRA uses Box 14 as the starting point for your taxable employment income on the T1. Box 14 typically equals Box 24 (EI insurable earnings, subject to the annual EI maximum) and is closely related to Box 26 (CPP/QPP pensionable earnings) when both caps are not exceeded.
If you had multiple employers, each employer issues its own T4 and each Box 14 is reported separately on Line 10100 (they add up).
Tax return implications
- Flows to Line 10100 (employment income) of the T1 general return.
- Forms the base for computing federal and provincial income tax.
- Determines RRSP deduction room for the following year (18% × prior-year earned income).
Common pitfalls & things to check
- Taxable benefits already included in Box 14 are broken out separately in Box 40 (and sometimes in the "Other Information" area as codes 30-42). Don't double-count.
- If Box 14 includes a retiring allowance, check whether Box 66 / 67 also apply — those have different tax treatment.
FAQ
Why is my Box 14 higher than my base salary?
Box 14 includes bonuses, commissions, overtime, vacation pay and any taxable employer benefits (company car, premiums, gift cards over $500, etc.). All of those are added to gross salary.
Does Box 14 include my RPP pension contributions?
Yes — Box 14 is gross, before RPP is withheld. Your RPP contributions appear separately in Box 20 and are deducted on your return at Line 20700.
