Alberta Second Job Calculator

About This Calculator

This Alberta Second Job Calculator estimates the tax implications of income from a second job. When you have multiple employers in Canada, each may withhold tax independently. Your second employer may use a different provincial tax rate or assume you have no personal exemption (since it is used by your main job). The calculator helps you estimate take-home pay from the second job and plan for possible tax owing or refunds at year-end in Alberta.

How Is Second Job Income Taxed in Alberta?

Second jobs are taxed as employment income. Your main employer typically uses your basic personal amount and deducts tax based on your primary income. Your second employer may be instructed by the CRA to withhold tax at a higher rate, often with reduced or no personal amount.

Federal and provincial tax (Alberta) apply to combined income. CPP and EI are calculated per employer—you may pay CPP and EI on both jobs until you hit the annual maximums. This can lead to over-withholding early in the year, reconciled when limits are reached.

At year-end, you file one return with total income from all sources. The CRA calculates your true tax liability and issues a refund if you overpaid. This calculator provides an estimate for budgeting; for exact withholding, check with the CRA or your payroll provider.
