The moment a services-led startup brings on its first person who is not a client-facing founder, a developer, a coordinator, someone doing ongoing work for the business itself rather than a single project engagement, three decisions land at once: whether that person is an employee or a subcontractor, whether payroll needs to be set up, and whether they get a T4 or a T4A at year-end. Getting any one of these wrong at the start creates a correction problem later, at exactly the point the business has the least spare capacity to deal with it.
Classification Comes First, Before Payroll or Reporting
The employee-versus-subcontractor question determines everything downstream, and it has to be answered based on the actual working relationship, not on which label is administratively easier. The full CRA classification factors, control, tools and equipment, chance of profit and risk of loss, and integration into the business, are covered in employees vs. subcontractors in an IT consulting firm.
For a startup making its first hiring decision, the practical version of this question is usually straightforward: someone working set hours, using the firm’s own systems and equipment, taking direction on day-to-day work, and having no other clients of their own is functioning as an employee, whatever the engagement letter calls them. A firm’s first instinct is often to keep the relationship as a subcontractor arrangement because it avoids payroll setup entirely, but that avoids the administrative cost, not the underlying classification question, and misclassifying an actual employee as a subcontractor is a risk that compounds the longer it continues, since it typically means several months or years of missed source deductions to correct if CRA reassesses.
Setting Up Payroll
Once the first genuine employee is confirmed, a payroll program account needs to be registered with CRA before the first pay period, distinct from the corporation’s existing business number. This is the account source deductions, CPP, EI, and income tax withheld from the employee’s pay, are remitted through.
Setting this up involves a handful of practical decisions a first-time employer has not had to make before:
- Remittance frequency. Most new small employers remit monthly, though the frequency is generally assigned by CRA based on the employer’s average monthly withholding amount and can change over time as payroll grows.
- Provincial or territorial registration. Workers’ compensation coverage (WSIB in Ontario, CNESST in Quebec, and the equivalent body elsewhere) is generally mandatory once an employee is on payroll and is a separate registration from the federal payroll account.
- Payroll software or service. QuickBooks Online payroll, a dedicated payroll provider, or a manual process, chosen with an eye to how the calculation, remittance, and year-end T4 filing will actually get done reliably each pay period, not just for the first one.
This is genuinely new administrative infrastructure for a firm that has run on contractor invoices and founder draws up to this point, and it should be set up before the first pay period, not reconstructed afterward once the first payment has already gone out without withholding.
T4 Versus T4A: Getting the Right Slip to the Right Person
At year-end, the classification decision made when the person was hired determines which slip they receive, and the two are not interchangeable:
T4, Statement of Remuneration Paid is issued to an employee, reporting salary or wages along with the CPP, EI, and income tax withheld at source throughout the year. Filing a T4 confirms the source deductions were remitted correctly through the year, not just calculated at year-end.
T4A, Statement of Pension, Retirement, Annuity, and Other Income is issued in a narrower set of circumstances, most commonly for fees paid to certain unincorporated subcontractors for services. It reports gross amounts paid, with no source deductions withheld, since the recipient is responsible for their own tax remittances as a self-employed individual.
Issuing a T4A to someone who was actually functioning as an employee through the year does not retroactively make the relationship a subcontractor arrangement. If CRA reviews the file and determines the person was an employee, the firm is generally on the hook for the source deductions that should have been withheld throughout the year, on top of correcting the reporting itself. The slip issued at year-end should reflect the classification decision made honestly at the start of the engagement, not a default chosen because it required less paperwork in the moment.
The Transition Point in Practice
A startup moving from all-contractor delivery to its first employee typically hits this transition while still managing tight cash flow and an evolving business, which is exactly when payroll setup gets deferred or handled informally. The practical sequence that avoids the most common mistakes:
- Confirm the classification honestly, based on the actual working relationship, before an offer or agreement is finalized.
- Register the payroll account and workers’ compensation coverage before the first pay period, not after.
- Set the remittance schedule and calendar it alongside existing GST/HST and instalment deadlines, so the new obligation is visible in the same compliance tracking the corporation already runs.
- Issue the correct slip, T4 for the employee, T4A only for the subcontractors whose classification genuinely supports it, at year-end.
This transition point is a natural moment to also revisit founder compensation, since a founder who was drawing informally or taking dividends may choose to move onto the same payroll infrastructure being set up for the first employee, resolving both compensation questions through one registration rather than two.
