When BC replaced MSP premiums with the Employer Health Tax, most small businesses looked at the threshold, saw they were under it, and stopped reading. Reasonable — but the tax has two features that catch growing Fraser Valley companies later: a steep notch just above the exemption, and an association rule that quietly combines related companies' payrolls. Here is the whole system in plain terms.
Quick answer: BC employers with $1,000,000 or less of BC payroll in a calendar year pay no Employer Health Tax. Between $1,000,000 and $1,500,000, EHT is 5.85% of payroll above the $1M line. Above $1,500,000, it is 1.95% of the entire payroll. Associated employers share one exemption. Registration is due December 31 of your first taxable year, the return and payment by March 31 following, with instalments (June 15 / September 15 / December 15) for larger payers.
How the math works
EHT is calculated on BC remuneration — broadly, the payroll amounts you report for employees at or reporting to a BC establishment: salary, wages, bonuses, most taxable benefits.
- $1,000,000 or less: exempt. No tax, and no return required if you are under the threshold.
- $1,000,000 to $1,500,000: tax is 5.85% × (payroll − $1,000,000). At $1.2M payroll that is 5.85% of $200,000 = $11,700.
- Above $1,500,000: tax is 1.95% × total payroll, from the first dollar. At $1.6M that is $31,200.
The 5.85% notch exists so the two formulas meet at $1.5M (5.85% of $500,000 = 1.95% of $1.5M = $29,250). The practical effect: in the notch, every additional payroll dollar costs an extra 5.85 cents of EHT — triple the headline rate. A raise, a new hire or a year-end bonus that nudges a $1.4M payroll upward is more expensive than it looks, and worth timing deliberately alongside the bonus-vs-dividend decision.
The association trap
Related employers — corporations under common control, and similar structures — must share a single $1,000,000 exemption, split however they agree. The parallel with the associated-corporation rules for the small business deduction is deliberate: you cannot multiply thresholds by multiplying companies. Two related companies with $700,000 of payroll each are $400,000 over the combined line; and if the combined payroll exceeds $1.5M, no exemption is available to any of them. Owners with an operating company and a second business — common in construction and farming families — should check this before assuming they are exempt twice.
Where EHT fits in your payroll stack
EHT sits alongside, not inside, your existing payroll obligations. A BC employer with staff typically carries: CRA source deductions (income tax, CPP, EI — remitted through your RP account), WorkSafeBC premiums (registration is generally required when you hire), T4 filing by the end of February, and — only above the threshold — EHT. It is employer-paid entirely: nothing is withheld from employees for it. For most small businesses hiring their first employees, the correct amount of EHT attention is simply confirming you are under $1M and moving on; the mistake is failing to re-check as payroll grows or a second company appears.
Deadlines that matter
- Registration: by December 31 of the first calendar year you owe EHT.
- Annual return and final payment: March 31 of the following year.
- Instalments: June 15, September 15 and December 15 for employers above the instalment threshold — missing them accrues interest just like CRA instalments.
Planning around the threshold honestly
There is legitimate planning here — timing a discretionary bonus across calendar years, weighing salary against dividends for owner pay (dividends are not remuneration for EHT), structuring genuinely separate businesses properly — and there is wishful thinking, like recharacterizing employees as contractors, which creates a worker-classification problem far more expensive than the tax it dodges. The right time to look at EHT is when payroll passes about $800,000 and is climbing: that is when the notch, the association rules and compensation design start interacting, and when a year of advance planning has real value.
