How to Set Up Payroll for a New Business With the CRA
Payroll tax requirements for Canadian startups begin with a single registration step, and getting it wrong is the most expensive mistake a new company makes.
Registering for a Business Number and Payroll Account
The Canada Revenue Agency issues a business number, and your payroll account is a program account attached to it. Register before your first pay run, not after. Have your legal name, business address, ownership details, and expected monthly payroll figure ready. Registration is free, and the CRA confirms your account number in writing. That number goes on every remittance and slip you file.
Running a pay run before your payroll account exists forces you to remit late, and late remittance attracts penalties and interest calculated from the original due date. Register first, pay second.
Employee vs. Contractor Classification
Employee classification determines whether you withhold at source at all. A worker is generally an employee when you control their hours, tools, and method of work; an independent contractor controls those themselves. The distinction is not a label you choose in a contract. Misclassifying a contractor who is functionally an employee leaves you owing unremitted source deductions, employer contributions, and penalties at once.
Federal and Provincial Income Tax Withholding for Startups
Income tax withholding is the portion of each employee’s pay you hold back and send to the government on their behalf, calculated using federal and provincial tax brackets, the employee’s completed TD1 forms, and the CRA’s payroll deduction tables. It is a pass-through, not your money or your cost, treating it as working capital is how startups end up in a CRA collections file.
How Tax Brackets and TD1 Forms Shape Deductions
Federal tax brackets set the rate for each slice of taxable income, and provincial brackets layer on top. The TD1 federal and provincial forms tell you which personal credits the employee claims, changing the tax withheld even at an identical salary. An employee who files a new TD1 mid-year expects you to adjust, so build a check into your onboarding.

CPP and EI Contribution Rates Employers Must Budget For
Canada Pension Plan contributions and Employment Insurance premiums are statutory deductions with an employer share on top. You withhold the employee portion, add your own contribution, and remit the combined amount.
Budget the employer portion as a fixed percentage of pensionable and insurable earnings, and remember both have annual ceilings. Once earnings pass the yearly maximum, contributions stop for the year, making December cheaper than January for high earners.
| Deduction | Employee portion | Employer portion | Annual ceiling applies |
|---|---|---|---|
| CPP contributions | Withheld from pay | Matched by employer | Yes, on pensionable earnings |
| EI premiums | Withheld from pay | Employer pays a multiple of the employee rate | Yes, on insurable earnings |
| Federal and provincial tax | Withheld from pay | None | No, brackets apply per slice |
| Employer health tax | None | Employer pays | Varies by provincial program |
The employer share of CPP and EI is a real payroll cost that never shows up in an employee’s pay stub. Model it separately in your hiring plan or every new hire will cost more than your spreadsheet says.
CRA Payroll Remittance Deadlines and Penalties
CRA payroll remittance deadlines depend on your remitter type, and missing them triggers penalties and interest that compound. Most new employers remit quarterly until withholding exceeds the threshold that pushes them to monthly. The CRA assigns your remitter type in writing, do not guess it.
Choosing Your Remittance Frequency
Your remittance frequency is set by the CRA based on average monthly withholding, not preference. A quarterly remitter sends four remittances a year; a regular remitter sends monthly by the 15th of the following month. Once withholding passes the threshold, the CRA moves you to a higher frequency, and continuing quarterly after that counts as late. Check your remittance notice after every filing season, because your average changes as you hire.

Employer Health Tax and Provincial Payroll Requirements
Employer health tax is a provincial payroll cost, and it follows your permanent establishment, not your head office address. That is where most startup payroll budgets break, because a permanent establishment can be created by an employee working from a home office in another province. The province can then require you to register, calculate, and remit its payroll levies even if every other employee sits in your home province.
How Provincial Payroll Levies Actually Work
Several provinces run an employer health tax or payroll levy with its own exemption threshold, rate structure, and filing calendar; others run none. The mechanics differ in ways that matter to a founder modeling cost:
- Some programs exempt the first slice of annual payroll, so a small team pays nothing until total remuneration crosses the threshold.
- Some apply a flat rate above the exemption; others use graduated rates that step up as payroll grows.
- Some are administered by the province’s finance ministry; others are administered alongside the provincial tax return.
Because thresholds and rates are set provincially and change with each budget, confirm current numbers for every province where you have a permanent establishment before finalizing a hiring plan. A payroll platform that only knows federal tax tables will not catch a provincial levy you never registered for.
Multi-Province Payroll Nexus for Remote Teams
This is the gap most compliance guides skip. When you hire someone who works from another province, that province generally gains the right to tax their employment income and apply its own employment standards. In practice:
- Provincial income tax withholding is calculated using the employee’s province of employment, not your office location. Your payroll system needs a separate provincial tax calculation per employee.
- Provincial payroll levies may apply to that employee’s remuneration if the work location creates a permanent establishment.
- Employment standards, minimum wage, overtime rules, vacation pay, statutory holiday pay, and termination entitlements, follow the province where the employee actually works.
- Workers’ compensation registration is typically required in the province of the employee’s work location, separate from payroll tax.
A common pattern: a founder registers only in their home province, hires three remote employees across two other provinces, and discovers the gap at year-end. The fix is to map every employee’s province of work before the first pay run, then register in each province that nexus triggers.
Provincial payroll obligations are triggered by where the employee works, not where your company is incorporated or where your bank account sits. Registering late does not remove the obligation, it adds penalties and interest calculated from the original due date.
Employment Standards Feed Directly Into Each Pay Run
Payroll tax and employment standards are separate legal regimes, but they meet in your payroll register. Minimum wage, overtime, vacation pay accrual, statutory holiday pay, and termination pay are all provincial, and they all change what an employee is owed in a period. A system that withholds the correct tax but applies the wrong province’s vacation accrual rule still produces non-compliant pay, and a wage statement that will not survive an employment standards complaint.
Provincial and territorial payroll information for employers
Before your first out-of-province hire, build a one-page nexus map: employee name, province of work, provincial tax registration required, payroll levy registration required, workers’ compensation registration required. Update it every time someone relocates. It is far cheaper to set up the deduction correctly in month one than to amend a year of remittances.
Payroll Tax Credits and Equity Compensation for Startups
Two areas separate a founder-first payroll guide from a generic compliance checklist: credits that reduce payroll cost, and equity that changes taxable income. They are exactly where early-stage companies either leave money on the table or create a withholding liability they never modeled.
SR&ED and Other Payroll-Linked Credits
The Scientific Research and Experimental Development program is a federal tax incentive, and eligible salaries and wages are frequently the largest qualifying expenditure for a software or hardware startup.
To support an SR&ED claim on payroll, you generally need:
- Per-employee wage records tied to specific qualifying projects, not a single blended salary figure.
- Time records that allocate each employee’s hours between qualifying and non-qualifying work.
- A payroll register that reconciles to the T4 slips issued for the same employees.
Reconstructing that allocation after the fact is painful and often reduces the claimable amount. Build project-level time tracking into payroll from the first hire, not the first claim.
Other payroll-linked programs worth reviewing with your accountant include provincial research and development credits, which some provinces calculate on the same eligible wage base, and hiring incentives that reduce the employer’s share of contributions for certain new employees.

Tax Treatment of Stock Options and RSUs
Equity-based compensation creates a taxable benefit, and a taxable benefit is a payroll event. Founders routinely treat option grants as a legal and cap-table matter and discover at exercise time that payroll had a role all along.
The general mechanics a founder needs to understand:
- Grant. Issuing options is typically not a taxable event by itself, but the grant terms and the fair market value at grant set up the tax treatment at exercise.
- Vesting. Vesting is usually not a taxable event, but it is the point at which the employee’s economic interest becomes real and the clock on withholding starts.
- Exercise. When an employee exercises options, the difference between the exercise price and the fair market value of the shares is generally a taxable employment benefit. That benefit appears on the employee’s T4 slip and can trigger a withholding obligation on the employer.
- Disposition. When the employee later sells the shares, a separate capital gains calculation applies, which is outside payroll but depends on records payroll should have kept.
Restricted share units follow a different path: the value is generally taxed when the units vest or are settled, and that value is a payroll event.
A taxable stock option benefit can create a withholding obligation larger than the employee’s regular pay for that period. If your payroll system cannot handle a withholding amount that exceeds net pay, you will either under-withhold and expose the employee to a tax bill, or over-withhold and breach employment standards. Model the exercise scenario before you grant, not after.
Coordinating Legal, Accounting, and Payroll Before You Grant
The practical rule for startups: loop payroll into the equity conversation before the grant, not at exercise. Legal drafts the plan, your accountant models the tax, and payroll needs the grant date, exercise price, vesting schedule, and settlement mechanism so the taxable benefit lands on the right T4 in the right year. When those three functions share data, equity is a retention tool.
Payroll-linked credits and equity compensation are the two places where a startup’s payroll decisions have the largest financial consequences. Both reward getting the record-keeping right from day one, and both punish reconstruction after the fact.
Record Keeping, Payroll Software, and Year-End Reconciliation
Year-end reconciliation is where the whole year gets checked, and it is unforgiving. You issue a T4 slip for each employee, file a summary, and reconcile every dollar remitted against what you actually owed.
Good bookkeeping makes this a routine task instead of a scramble. Keep these records, and keep them for the period the CRA requires:
- Payroll register showing gross pay, each deduction, and net pay per employee per period
- TD1 federal and provincial forms, signed and dated
- PD7A remittance forms and confirmation of each payment
Payroll software handles the arithmetic, tax tables, and slips.
Payroll tax requirements for Canadian startups are not complicated one at a time; they are complicated in combination, especially once you add provinces, contractors, and equity.
Frequently Asked Questions
What are the mandatory payroll deductions for employees in Canada?
Employers must withhold three statutory deductions from each paycheque: federal and provincial income tax, Canada Pension Plan (CPP) contributions, and Employment Insurance (EI) premiums. Employers also pay their own share of CPP and EI on top of the employee’s portion. These amounts must be remitted to the CRA by your assigned deadline, which is typically the 15th of the following month for regular remitters. Missing the deadline triggers penalties and interest.
When are payroll remittances due to the CRA?
CRA payroll remittance deadlines depend on your remitter type. Regular remitters pay by the 15th of the month following the pay period. Quarterly remitters (withholding $3,000 or less per month) pay by the 15th of the month after each quarter ends. Threshold 1 and Threshold 2 remitters, who withhold larger amounts, must remit more frequently, sometimes within three business days of payday. New employers start as regular remitters until the CRA reviews their account.
How do I register for a payroll program account with the CRA?
You need a nine-digit business number before you can open a payroll account. Register through the CRA’s Business Registration Online service, by phone, or by mail. Once you have your business number, add a payroll program account (RP) using the same channels. You will need your legal business name, address, owner information, and the estimated monthly withholding amount. Registration is free and usually processed within a few business days.
What happens if a startup fails to remit payroll taxes on time?
Late remittances trigger a penalty of 3% on the amount owed if you are one to three days late, 5% for four to five days, 7% for six to seven days, and 10% if you are more than seven days late. Interest also accrues daily on the unpaid balance. Repeated failures can lead to a demand for direct payment or a requirement to post security. Directors can be held personally liable for unremitted source deductions.
Are there specific payroll tax requirements for startups with remote employees?
Yes. Remote employees working in a different province than your head office are subject to that province’s income tax rates and, in some cases, its employer health tax. You must also confirm whether the employee is covered by the employment standards of their province of residence. If you have no physical presence in a province but employ someone there, you may still need to register a provincial payroll account or remit tax to that jurisdiction.
What is the difference between CPP, EI, and income tax deductions?
CPP contributions fund the Canada Pension Plan and are based on pensionable earnings up to the yearly maximum. EI premiums fund Employment Insurance and are calculated on insurable earnings up to a set ceiling. Income tax is withheld based on federal and provincial brackets and the TD1 forms your employee submits. CPP and EI have fixed rates for 2026, while income tax varies by province and personal credits claimed.
