Management consultant payroll: paying associates, staff, and yourself correctly

Associate or employee — the test does not care what the contract says

A consulting firm that scales usually does it with subcontracted associates before it does it with staff, and the appeal is obvious: no source deductions, no vacation pay, no WSIB premium on that person's earnings. The risk is that CRA decides the relationship regardless of what the contract calls it — control over how and when the work is done, whose tools are used, and whether the associate carries their own business risk and other clients all weigh more than the label on the agreement. An associate who works exclusively for you, at your direction, using your templates and your project management tools, looks like an employee even if every invoice says "consulting fees."

We review the working pattern, not just the paperwork, before an associate relationship becomes a habit rather than a one-off. Where the facts support it, associates are paid on invoice and tracked to a T4A; where they do not, the fix is a proper offer, not a workaround.

Travel per-diems: the line between reimbursement and taxable benefit

Client-site work means flights, hotels, and meals, and how you reimburse them determines whether the amount is tax-free to the employee or a taxable benefit that belongs on their T4. An accountable advance or reimbursement — actual receipts, or a reasonable flat per-meal rate tied to real travel days — stays out of income. A flat travel allowance paid regardless of whether the trip happened, or one set well above what the trip actually cost, tends to draw scrutiny and can be added to pay. For staff who travel into the US regularly, benchmarking your per-diem policy against published US government per-diem rates for the city in question is a reasonable way to defend the amount as reasonable if it is ever questioned.

• Mileage reimbursed at a reasonable per-kilometre rate for client-site visits stays non-taxable when logged properly.
• Hotel and flights booked or reimbursed against receipts are straightforward expense recoveries, not pay.
• Flat daily allowances need a defensible basis — tie them to an actual travel schedule, not a round number.

Payroll for the firm itself, once you hire staff

Once a consulting practice adds researchers, project coordinators, or junior consultants as employees, ordinary payroll obligations apply: CPP, EI, and income tax source deductions remitted on the CRA schedule your remittance frequency requires, T4 slips at year-end, and vacation pay under the Employment Standards Act. Many office-based advisory firms fall outside WSIB's list of compulsory industries, but classification depends on your specific activities, so confirm your firm's status directly with WSIB rather than assuming either way.

One quirk worth knowing if you also draw a T4 salary from your own corporation: an owner-manager who controls more than 40% of the corporation's voting shares is generally excluded from EI as a non-arm's-length employee and can choose not to pay EI premiums on that salary. It is a small saving on its own, but it changes the payroll setup for the owner compared to every other employee on the T4 run.

We run this on Wagepoint or a comparable Canadian payroll platform, synced to the bookkeeping so payroll costs land against the right engagement for margin reporting. Associates stay in a separate T4A workflow entirely, so the two never blur together on the books or in a CRA reviewer's mind.

Bonuses to a working owner or senior consultant are common after a strong project year, and there is a legitimate planning tool worth using deliberately: a corporation can accrue and deduct a bonus in the fiscal year it is declared, provided it is actually paid within 180 days of that year-end. That lets a firm reward a good year without locking the amount into ongoing base salary, as long as the timing is tracked and the payment actually happens on schedule.

Where cross-border work changes the payroll picture

A consultant who spends weeks on-site with a US client is not on that client's payroll, but the travel itself creates questions worth planning for — state-level withholding some US states apply to non-resident service providers, and how per-diems for US travel are tracked in your own books. Our cross-border tax guide for consultants covers the US side; this page is about paying the people who do the work.
