Profit on paper and cash in the bank are not the same thing. You can show a healthy year and still struggle to make payroll, GST, or supplier payments because the money has not arrived yet, or because it already went out the door.
This guide is a practical cash-flow primer for BC sole proprietors and incorporated owners. It covers what cash flow is, where it gets tight, and the habits that keep you from being surprised. For bookkeeping, payroll, and contractor rules, see our Small Business & Self-Employed hub.
Profit is not cash
Profit is revenue minus expenses for a period, using accounting rules. Cash flow is money in minus money out of your bank account.
Gaps show up when:
- You invoice in March and collect in May
- You buy inventory or equipment before you sell it
- You remitted GST/HST or PST on sales you have not collected
- You took a draw or dividend that the bank account could not support
- A large CRA instalment, payroll remittance, or insurance bill hits in the same week
If you only look at the income statement, you will miss those timing problems. A simple cash-flow view (opening bank, plus receipts, minus payments, equals closing bank) answers the question owners actually care about: can we pay what is due this month?
Map the money in and money out
Write down a typical month. You do not need software for the first pass.
Money in: customer receipts (not invoices), GST collected when it actually hits the account, loan advances, owner injections, sale of assets.
Money out: suppliers, wages and source deductions, rent, insurance, loan payments, GST/PST remittances, income tax instalments, owner draws or dividends, purchase of equipment.
Separate operating cash (day-to-day) from tax cash (amounts you will owe the CRA or the Province) and owner cash (what you take home). Mixing those three is how a “good month” still ends overdrawn.
Keep the records behind those numbers. If you cannot explain a deposit or a payment, you cannot manage cash or defend a return to the CRA.
The tax calendar is a cash-flow calendar
In Canada, tax dates are cash dates.
- GST/HST: You generally remit based on your filing period (monthly, quarterly, or annually), not on when every customer pays you. If you use the invoice basis, you can owe GST on receivables. That is a cash crunch, not an accounting trick.
- Payroll: Source deductions are due on the CRA’s remittance schedule. Late remittances attract penalties and interest quickly.
- Personal tax: If you are self-employed, the T1 can be due June 15, but any balance is still due April 30. Instalments, if you are required to pay them, are separate cash events.
- Corporate tax: The T2 is due six months after year-end, but the balance is usually due two months after year-end (three months for some CCPCs). See Corporate Tax Filing Deadlines in Canada.
- BC PST: If you sell taxable goods or services in BC, PST remittances have their own cycle. Professional services PST expands on October 1, 2026 for many firms. If that applies to you, build the extra outflow into the forecast. Details: BC PST on Professional Services.
- BC Employer Health Tax: If your BC payroll is high enough to be in the EHT net, instalments and the annual return are more cash you must plan for.
Put these dates on the same calendar as rent and payroll. Tax surprises are usually calendar surprises.
Receivables, payables, and payroll
Three operating levers move cash faster than a new loan:
Receivables. Invoice promptly. State payment terms. Follow up. Deposits or progress billing help project-based work. If one customer is a large share of sales, your cash flow is their payment habit.
Payables. Stretching every supplier to the last day can damage relationships and credit. Pay tax and payroll first. Negotiate terms before you need them, not after a missed payment.
Payroll. Hiring changes cash before it changes profit. Employees mean regular remittances. Contractors mean invoices and possible T4A or T5018 reporting. Get the classification right before you promise a start date. See Employee or Contractor? CRA Rules for Canadian Small Businesses.
A simple 13-week habit
Once a quarter is not enough when cash is tight. Many owners do well with a rolling 13-week cash forecast:
- Start with today’s bank balance (and the line of credit available).
- List expected receipts by week (be conservative).
- List payroll, rent, tax, and supplier payments by week (be complete).
- Flag any week that goes negative.
- Decide in advance: collect faster, delay a non-essential purchase, use the operating line, or inject funds.
Update it weekly. The first version will be wrong. The point is to see the dip before it happens.
If the forecast is always a scramble, that is often the signal to get bookkeeping on a schedule and bring in outside help before a bad month becomes a bad quarter.
Owner draws, dividends, and the operating line
Taking money out of the company feels like “your” cash. The bank and the CRA still see a business account with obligations.
- A draw (sole prop) or dividend/salary (corporation) should come after you know tax and payroll are covered.
- An operating line is for timing gaps, not for losses that never reverse. If you are rolling the line up every year, the issue is profitability or a structural working-capital gap, not a bad week.
- Mixing personal and business spending hides the real cash position and creates bookkeeping and GST problems.
If you pay yourself from a corporation, salary and dividends have different cash and tax timing. Salary vs. Dividends in Canada covers the tax side; this post is the reminder to check the bank first.
FAQ
What is the difference between profit and cash flow?
Profit is an accounting result for a period. Cash flow is actual money moving through the bank. You can be profitable and short of cash, or unprofitable in a month and still liquid if receivables catch up or you take on debt.
How much cash should a small business keep on hand?
There is no single CRA number. Many owners aim for enough to cover a few weeks of payroll, rent, and tax remittances if sales pause. Your buffer depends on how lumpy receipts are and whether you have a line of credit.
Does GST I collect belong to me until I remit?
No. Treat it as money you are holding for the government. Spending it as if it were profit is a common way to create a remittance crisis.
When is corporate tax actually due?
The T2 return is due six months after year-end. The balance is generally due two months after year-end (three months for some CCPCs). Plan the payment date, not only the filing date.
Does BC PST on professional services affect my cash flow?
Yes, if your services are affected. Starting October 1, 2026, you will collect extra cash from customers and remit it on your PST schedule, which is a timing and systems issue as much as a tax issue. See our PST for professional services post.
