The case for one team, two jobs
Most small businesses end up with bookkeeping in one place and payroll in another — a payroll app the owner runs, plus a bookkeeper who reconciles the bank afterward. It works, until it does not. The wages in the payroll app and the wages in the books drift apart, the source-deduction remittances do not match the liability on the balance sheet, and at year-end someone has to reconcile two systems that were never designed to agree.
Combining bookkeeping and payroll under one team fixes this at the root. The same people who run pay also keep the books, so every paycheque, every remittance, and every year-end slip flows straight into your financial statements with nothing to reconcile after the fact. Here is what actually gets better.
Source deductions are where it goes wrong
Payroll is not just paying people. Every pay run, you withhold and remit to the CRA:
- CPP contributions — for 2026, 5.95% from the employee and a matching 5.95% from the employer, on pensionable earnings between the $3,500 basic exemption and the $74,600 maximum — a maximum base contribution of $4,230.45 each — plus CPP2 at 4% on earnings between $74,600 and $85,000, a maximum CPP2 contribution of $416.00 each.
- EI premiums — for 2026, $1.63 per $100 of insurable earnings from the employee, and the employer pays 1.4 times that ($2.28 per $100), up to the $68,900 maximum insurable earnings.
- Income tax — withheld per the employee's TD1 and the federal and provincial tax tables.
(All 2026 figures above are from the CRA's published rates and maximums.)
That withheld money is not yours. From the moment you deduct it, it is a liability you owe the CRA, and it has to land on your balance sheet as one. When payroll and bookkeeping are separate, this liability is the thing that most often goes uncounted — the cash is in the bank, it looks like yours, and it gets spent. When the same team runs both, the deduction posts to the books as a liability the instant it is withheld, so you always know exactly what you owe and when.
Remittance timing is a bookkeeping problem too
The CRA assigns every employer a remitter type based on average monthly withholding, and the type sets your deadline:
- Quarterly remitter — small employers with under $3,000 average monthly withholding and a clean compliance record; remit quarterly.
- Regular (monthly) remitter — average monthly withholding under $25,000; remit by the 15th of the month after you pay employees.
- Accelerated, threshold 1 — average monthly withholding of $25,000 to $99,999.99; remit twice a month.
- Accelerated, threshold 2 — $100,000 or more; remit within three working days of each pay period.
(Verified against the CRA's remitter-type and due-date guidance.)
Miss a remittance deadline and the CRA charges a penalty plus interest. Knowing your remitter type, tracking the deadline, and having the cash set aside is as much a bookkeeping job as a payroll job — which is exactly why splitting the two creates gaps. One team running both watches the deadline and the liability together.
What gets cleaner when they are combined
When bookkeeping and payroll live together, several things stop being problems:
- Wages always match the books. No reconciling two systems — payroll posts directly to the ledger.
- Source-deduction liabilities are always current. The balance sheet shows exactly what is owed to the CRA at any moment.
- WorkSafeBC and the BC Employer Health Tax are tracked in the same place as the payroll that drives them, so nothing is forgotten.
- Year-end is calm. T4s and T4As are produced from the same data that fed the books all year, so the slips and the statements already agree.
- Your statements are accurate. Labour is your biggest cost in most businesses — when it is recorded properly through integrated payroll, your P&L finally tells the truth.
The first-employee moment
The cleanest time to combine them is when you hire your first person, because that is when payroll obligations switch on all at once — a CRA payroll account, WorkSafeBC, source deductions, the works. Setting it up integrated from day one avoids the messy untangling later. We walk through the whole setup in our guide to setting up payroll for your first employee in BC.
If you already have payroll running separately, combining it is still worth doing — the reconciliation savings and the accuracy gains show up the first month.
How Fluent Books bundles them
At Fluent Books, payroll is built into the Growth tier from $997 CAD a month, sitting alongside your bookkeeping rather than as a separate service to coordinate. The same team that reconciles your accounts runs your pay, remits your source deductions, handles WorkSafeBC and BC Employer Health Tax reporting, and produces your T4s — from one employee to a full team. Wages, remittances, and reports always match your financial statements because they come from the same place.
Frequently asked questions
Should bookkeeping and payroll be done by the same provider?
For most small businesses, yes. When the same team runs both, wages post directly to the books, source-deduction liabilities stay current on the balance sheet, and year-end T4s already agree with your statements. Splitting them across two providers or two systems is the main source of the reconciliation headaches owners complain about.
What payroll deductions do I have to remit to the CRA?
CPP contributions, EI premiums, and income tax withheld from each employee. For 2026, CPP is 5.95% each from employee and employer on earnings up to $74,600 (plus CPP2 to $85,000), and EI is $1.63 per $100 from the employee with the employer paying 1.4 times that. The combined amount is remitted on the schedule set by your CRA remitter type.
How often do I have to remit payroll source deductions?
It depends on your remitter type, which the CRA sets from your average monthly withholding. Regular remitters pay monthly by the 15th; quarterly remitters (small, compliant employers) pay quarterly; accelerated remitters pay twice a month or within three working days of payday for the largest payrolls.
