Why use the CRA 2026 payroll calculator

The CRA Payroll Deductions Online Calculator, or PDOC, helps you figure out federal and provincial payroll deductions like income tax, CPP, and EI premiums. It's updated by the Canada Revenue Agency with current year rules and thresholds. You can use it for quick calculations on a single paycheck or to double-check what your payroll software gives you.

Prerequisites

Before running the PDOC or setting up regular payroll, make sure you have a few things ready.

  • Business Number (BN) with a payroll program account — register at Business Registration Online (BRO) on canada.ca; registration is free.
  • Employees' legal names, Social Insurance Numbers (SINs), and addresses.
  • Pay period schedule (weekly, biweekly, semi-monthly, monthly) and pay dates.
  • Gross pay amounts, taxable benefits, and pensionable earnings for each employee.
  • Access to CRA online services (My Business Account or Represent a Client) for remittances and filing — sign-in options are at https://www.canada.ca/en/revenue-agency/services/e-services.html.

Step-by-step: use the CRA 2026 payroll calculator

  1. Open the PDOC page. Go to the CRA payroll page and click "Payroll Deductions Online Calculator" or use this link: https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/withholding-tax/payroll-deductions-online-calculator.html. The PDOC runs in your browser — no install needed.

  2. Select province or territory. The PDOC asks for the employee's province or territory of employment because provincial tax rates and credits differ.

  3. Here's the thing — choose the pay period type and pay frequency. Pick the exact pay date. The calculator adjusts income tax calculations for the pay period frequency you select (weekly, biweekly, semi-monthly, monthly).

  4. Enter gross pay and taxable benefits. Put the employee's gross wages for that pay period into the gross pay field. If the employee received taxable benefits (e.g., personal use of a company car, taxable allowances), include those as well.

  5. Enter pensionable and insurable earnings. The PDOC will ask whether the pay is pensionable for CPP and insurable for EI. Answer according to your workplace plan and employment contract.

  6. Provide pension and other deduction details. If the employee participates in a registered pension plan or other payroll deductions (union dues, RRSP contributions withheld), enter those amounts so the net pay is accurate.

  7. Enter the employee's TD1 information. The PDOC uses federal and provincial TD1 personal tax credit amounts to calculate income tax. If the employee has completed TD1 forms with amounts beyond the basic personal amount, enter those figures.

  8. Run the calculation. The PDOC shows you how much federal and provincial tax is withheld, CPP and EI contributions from both employee and employer, plus the net pay. Print or save the results as a PDF for your records.

  9. Save payroll data or enter into payroll software. The PDOC is great for spot checks, new-hire setup or one-off adjustments. For repeated payroll runs, record the results in your payroll software or spreadsheet and compare totals against the PDOC periodically.

Remittance and filing steps (key dates and amounts)

After deductions are withheld you must remit them to the CRA and file information returns:

  • Remittances: for most employers the source deductions and employer contributions are remitted by the 15th of the month following the month in which the deductions were made. If you are an "accelerated remitter" the remittance schedule is shorter — check CRA online to confirm your remitter type.
  • T4 slips and summary: T4 slips and the T4 Summary for a calendar year are due on the last day of February following that calendar year. For 2026 payroll year reporting, T4s are due the last day of February 2027.
  • CPP and EI employer share: employer contributions for CPP are equal to the employee's CPP contribution; for EI the employer pays 1.4 times the employee premium in most provinces (Quebec has a different contribution for QPP/QPIP where applicable).
  • Registration: registering for a payroll account under your BN is free; there are no CRA fees to open a payroll program account.

Alternatives and comparisons

Comparing PDOC with payroll software:

  • PDOC: free, authoritative, great for single or occasional calculations, or to validate software output. No record-keeping automation.
  • Third-party payroll services (cloud payroll, full-service providers): automate calculations, remittances, T4 generation, and year-end filings. Prices vary — many providers offer plans starting around CAD 20–40 per month plus a per-employee fee; exact fees depend on the vendor and service level.

When choosing: smaller employers often start with PDOC and a spreadsheet, then move to a subscription payroll provider as employee count or compliance complexity increases.

Tips for accurate 2026 payroll calculations

  • Use the PDOC for spot checks: run a sample pay through PDOC monthly to catch rounding or configuration errors in your payroll software.
  • Keep TD1 forms current: if an employee's personal tax credits change mid-year, update the TD1 and recalculate net pay going forward.
  • Record the PDOC output: save PDFs or screenshots of each PDOC run. CRA audits expect supporting records that show how deductions were calculated.
  • Watch special cases: taxable benefits, commission pay, retroactive pay and severance often require special handling—use PDOC fields for taxable benefits or consult CRA publications on benefits and allowances.
  • Check remitter type early: remittance frequency can change with your payroll totals — confirm whether you're a regular or accelerated remitter to avoid late remittance penalties.

Common mistakes to avoid

Here are frequent payroll errors and how to prevent them:

  • Misreading TD1 entries — don’t assume basic personal amount applies if an employee claims additional credits; keep signed TD1 forms on file.
  • Missing CPP/QPP or EI reporting for benefits — report taxable benefits on the employee’s T4 and include them in payroll calculations when required.
  • Late remittances — set calendar reminders for the 15th of each month (or your accelerated remitter due dates). Penalties and interest apply when remittances are late.
  • Not matching CPP and EI records — reconcile payroll totals to monthly CRA statements (My Business Account) to catch errors quickly.
  • Assuming provincial rules are identical — payroll tax credits and surtaxes vary by province. Always select the employee’s province of employment in PDOC.

The CRA 2026 payroll calculator (PDOC) is the fastest way to get authoritative payroll deduction numbers for income tax, CPP/QPP and EI. Use PDOC for spot checks, new hires and complex pay situations, and combine it with a registered payroll account and consistent record-keeping to meet remittance and filing deadlines — generally remittances by the 15th of the following month and T4s by the last day of February. For recurring payroll, consider a payroll service that automates remittances and T4 generation, but keep PDOC handy to verify results.
