How to use the Equipment Purchase Tax Savings Calculator
This calculator estimates the Year-1 income tax savings from equipment purchases using Capital Cost Allowance (CCA). It compares first-year deduction approaches and shows the estimated tax saved based on an approximate provincial marginal rate.
Step 1 — Enter client and income
- Business income before CCA is the income available for deductions.
- Province sets the estimated marginal tax rate used for “Tax Saved”.
- Fiscal year-end is for reporting context.
Step 2 — Choose the Year-1 method
- Normal (Half-year rule): Year-1 CCA is typically ½ × rate × cost.
- AII (Accelerated Investment Incentive): Enhanced first-year CCA is commonly 1.5 × rate × cost (simplified).
- DIEP / Immediate expensing (if eligible): May allow up to 100% write-off in Year-1, subject to a limit.
Step 3 — Add equipment lines
- Enter up to 3 items (ID, Cost, GST/HST, CCA class, purchase date).
- Cost drives the CCA calculation. GST/HST is shown separately.
- Select the correct CCA class so the rate is applied properly.
Optional — Cap at income
- If enabled, the calculator limits Year-1 deductions so they don’t exceed the income entered.
- This helps avoid negative income in the estimate.
How to read the results
- DIEP = immediate expensing applied to the item (if selected and limit available).
- Year-1 CCA on remainder = either AII (if selected) or Half-Year (normal rule).
- Total CCA = DIEP + Year-1 CCA on remainder.
- Tax Saved = Total CCA × estimated marginal rate (province).
Important: This is an estimate and uses simplified assumptions. Actual eligibility and rates can vary by year,
taxpayer type, and property details. Confirm treatment before filing.
