Canada Payroll Deduction Changes Before the July 2026 Pay Run

• Payroll
• Tax
• Small Business

Canadian employers should check payroll deductions before the first July 2026 pay run. The Canada Revenue Agency (CRA) published the 123rd edition of T4127, effective July 1, 2026, and says employers should use the updated payroll deduction formulas, PDOC, T4032 tables or T4008 supplementary tables for withholding starting with the first payroll in July 2026.

For small businesses, the practical job is not to memorise formulas. It is to confirm the payroll tool is current, check employee TD1 details, review CPP, EI and income tax deductions, and keep the remittance and bookkeeping records clear.

The first July pay run is the control point. Check the CRA source, employee details, deductions, net pay and remittance records before payroll becomes a bank reconciliation clean-up job.

Quick answer

The CRA’s Payroll Deductions Formulas - 123rd Edition is effective July 1, 2026 and was modified on 2026-06-03. It covers federal, provincial except Quebec, and territorial income tax formulas, Canada Pension Plan (CPP) contributions and employment insurance (EI) premium deductions.

The July 2026 update is most visible for employers with employees in British Columbia, Newfoundland and Labrador, and Prince Edward Island. Employers outside those provinces should still check the first July pay run because payroll software, TD1 details, CPP, EI, remittance timing and accounting records all need to agree.

Key points

• Use the July 2026 CRA formulas, PDOC, T4032 tables, T4008 supplementary tables or a current payroll provider before the first July pay run.
• Check whether any employee works in British Columbia, Newfoundland and Labrador, Prince Edward Island, Quebec, or outside Canada.
• Review TD1 details and claim codes before relying on old payroll settings.
• Keep gross pay, deductions, net pay, employer contributions and remittance records traceable.
• Do not treat payroll deductions as business income or ordinary expenses in the books.

What changed for July 2026

The CRA says the July T4127 guide reflects income tax changes that, if enacted as proposed, would be effective July 1, 2026. It also says updates are highlighted in grey boxes in the official guide.

This article is a bookkeeping and payroll-control guide, not a substitute for CRA guidance, payroll software support or professional advice.

Who should check the first July pay run

Check the first July 2026 payroll if your business:

• pays employees in Canada
• has employees who report for work in more than one province or territory
• has employees in British Columbia, Newfoundland and Labrador or Prince Edward Island
• has a Quebec employee or uses a Quebec payroll workflow
• runs payroll in-house rather than through a payroll provider
• has employees with updated TD1 forms, extra tax deductions, bonuses, commissions or irregular pay
• has changed pay frequencies, employee locations or payroll software settings since January

If you use a payroll provider, ask what has been updated and when the July formulas are live. If you run payroll manually or through spreadsheets, this is the point to stop and move the calculation into an official calculator, current table or qualified payroll workflow.

Payroll deductions are not just one number

Canadian source deductions can include employee deductions and employer costs. A small-business owner should know which amount is paid to the employee, which amount is withheld, and which amount the employer must remit.

The CRA’s Payroll Deductions Online Calculator can calculate federal, provincial except Quebec, and territorial payroll deductions for common pay periods based on exact salary figures. The CRA also warns that the result depends on the accuracy of the information entered.

Simple example

Imagine a British Columbia cafe pays an employee every two weeks. The employee’s gross pay stays the same in July, so the owner is tempted to copy the June pay run.

That is the wrong control point. Before approving the first July pay run, the owner or payroll clerk should:

1. Confirm the payroll tool uses the July 2026 CRA formulas.
2. Check the employee’s province of employment and TD1 details.
3. Review CPP, EI and income tax deductions before paying net wages.
4. Record the wage expense, employer payroll costs and payroll liabilities clearly.
5. Match the employee bank payment and later CRA remittance during reconciliation.

The numbers may be calculated by payroll software or an official calculator, but the accounting file still needs the same trail: gross pay, deductions, net pay, employer costs and remittance.

TD1 details to review

TD1 forms tell payroll how much personal tax credit an employee claims. The CRA’s TD1 page links to 2026 federal and provincial or territorial TD1 forms for pay received on January 1, 2026 or later.

Before relying on old settings, check:

• the employee’s federal TD1 and provincial or territorial TD1
• whether the employee has more than one employer or payer
• whether the employee requested extra tax deductions
• whether the employee moved provinces or changed work location
• whether any disability, tuition, age, caregiver or other claim changed
• whether a new employee has provided complete information

For Newfoundland and Labrador specifically, the July 2026 CRA T4127 guide says employers do not need a new TD1NL just to change an earlier lower basic personal amount to the prorated amount. That does not remove the need to keep the employee’s actual TD1 record up to date.

Remittance records to keep

Payroll deductions become a trust and timing issue once the employer withholds them. The CRA’s Employers’ Guide - Payroll Deductions and Remittances explains that payroll deduction tables help calculate CPP contributions, EI premiums and federal, provincial except Quebec, and territorial income tax to deduct each pay period.

The same guide also explains remitter types and due dates. For regular remitters, deductions are generally due by the 15th day of the month after the month employees were paid. Quarterly and accelerated remitters have different timing, so check your CRA remitter type rather than guessing.

Keep these records together:

• payroll register or pay-run report
• employee statement of earnings or payslip equivalent
• bank payment to employees
• payroll liability account detail
• CRA remittance confirmation or payment record
• employer CPP and EI cost support
• notes for corrections, shortages, over-remittances or adjusted remittances

If your accountant asks why payroll liabilities do not match the bank payments, those records should answer the question without reconstructing the pay run from scratch.

What not to do

Avoid these July payroll mistakes:

• copying a June pay run without checking July formulas
• treating employee deductions as ordinary business expenses
• coding net pay only and losing the gross-pay and deduction trail
• forgetting employer CPP or EI costs in management reports
• using CRA federal/provincial tools for Quebec provincial deductions
• ignoring an employee’s province of employment
• missing the CRA remittance due date because payroll was reconciled late
• letting manual spreadsheet formulas drift from current CRA guidance

Payroll errors usually create both employee trust issues and bookkeeping clean-up. It is cheaper to check the first July pay run before the bank payment leaves.

How Gimbla fits the bookkeeping workflow

Gimbla does not replace CRA payroll formulas, PDOC, a payroll provider or professional payroll advice. For Canadian employers, the useful Gimbla role is the accounting record around payroll:

1. Keep bank payments visible during bank reconciliation.
2. Separate gross wages, employer payroll costs and payroll liabilities in the accounts.
3. Keep payroll deductions out of ordinary sales or GST/HST records.
4. Review cash flow before CRA remittance dates.
5. Keep supporting records close to reports for the accountant.

The Canada accounting software page is the right starting point for Canadian bookkeeping, invoices, GST/HST-aware records and reports. For local tax concepts outside payroll, the Canada Carbon Rebate bookkeeping guide shows the same principle: keep the source notice, bank movement and accounting treatment connected.

July payroll review steps

Before the first July 2026 pay run:

1. Open the current CRA T4127, PDOC, payroll tables or payroll provider update note.
2. Confirm each employee’s province or territory of employment.
3. Check TD1 details and any extra tax deduction requests.
4. Review gross pay, CPP, EI, income tax, employer costs and net pay before approval.
5. Save the payroll report and statement of earnings record.
6. Pay employees and reconcile the bank payments.
7. Remit CRA deductions by the date that matches your remitter type.
8. Reconcile the payroll liability account after the remittance clears.

For businesses with employees in more than one jurisdiction, write down which source was used for each employee. That habit helps when the accountant reviews payroll records at year end.

Frequently asked questions

What changed for Canadian payroll deductions in July 2026?

The CRA published the 123rd edition of T4127, effective July 1, 2026. The July update includes provincial changes for British Columbia, Newfoundland and Labrador, and Prince Edward Island, plus updated tables and claim-code information for the second half of 2026.

Does every Canadian employer need new TD1 forms for July 2026?

Not automatically. Employees should keep their TD1 details accurate, but a new TD1 is not required for every July formula update. The CRA specifically says Newfoundland and Labrador employers do not need a new TD1NL just to change an earlier lower basic personal amount to the prorated July amount.

Can small employers use the CRA Payroll Deductions Online Calculator?

Yes. The CRA says PDOC can calculate federal, provincial except Quebec, and territorial deductions for common pay periods using exact salary figures. The input still needs to be accurate, and Quebec provincial payroll deductions need Revenu Quebec guidance.

Does Gimbla calculate Canadian payroll deductions?

No. Use CRA tools, current payroll software, a payroll provider or professional advice for Canadian payroll calculations. Gimbla can help keep the bookkeeping around payroll payments, liabilities, bank reconciliation and reports organised.

In short

The July 2026 CRA payroll formulas are a prompt to check the first July pay run before it becomes a bank transaction. Use current CRA guidance or a current payroll provider, check TD1 details, review deductions, pay employees, remit on time and keep the accounting trail clear.

That gives the employer, bookkeeper and accountant one clean path from gross pay to net pay to CRA remittance.
