You Live in Canada. Your Paycheque Comes From the US.

A US employer can hire directly and arrange compliant Canadian payroll, use a Canadian entity or employer of record (EOR), or engage a genuinely independent business. An EOR is a company that becomes the legal employer and supplies your services to the client.

A US payroll slip does not by itself prove that withholding is correct or incorrect. Give payroll your work location and relevant tax-status information before accepting a proposed arrangement.

Canadian tax residents generally report worldwide income in Canadian dollars. Residency depends on the facts, including residential ties and any applicable treaty rules. Living in Canada does not automatically eliminate US reporting obligations.

For a person who is neither a US citizen nor a US tax resident, compensation for services performed entirely in Canada is generally foreign-source for US income-tax purposes. The payer being American does not by itself make that compensation US-source.

Report income using the Canadian-dollar conversion rules that apply to the payment. Keep records of exchange rates, dates and amounts. Employment and self-employment use different reporting lines and deductions.

A Canadian foreign tax credit is not an automatic reimbursement of every foreign withholding amount. Tax paid above what a treaty requires may be treated as voluntary and may not qualify. Review whether an incorrect amount should be recovered from the US instead.

• Give payroll your actual work locations, dates, Canadian residency information and relevant US tax status.
• Ask the employer or its adviser to determine Canadian payroll and reporting obligations. Personal instalments do not replace employer withholding duties.
• Review US income-tax withholding separately from Social Security and Medicare deductions.
• Determine which social-security system covers the work and obtain the appropriate certificate of coverage when needed.
• If withholding was incorrect, confirm the correction or refund procedure and filing deadline. Do not assume everyone should file Form 1040-NR.
• Check whether you need Canadian instalments based on the applicable tax-owing tests.

The Canada-US social-security arrangements coordinate coverage. Working in Canada does not always mean CPP: temporary assignments can remain under US coverage, and Quebec has a separate arrangement. A certificate records the applicable coverage; it is not an election to choose either system.

An employee in Canada may also create corporate-tax or employment-law obligations for the employer. A permanent establishment, meaning a taxable business presence, depends on the facts and treaty provisions rather than the employee's address alone.

If the relationship is genuinely self-employment, compare net business income with the full value of an employment offer. Include unpaid time, equipment, insurance, retirement contributions, administration and payment risk. There is no universal percentage markup that makes the offers equivalent.

• Budget for income tax and applicable self-employed CPP or Quebec contributions. Employment income in the same year can affect the calculation.
• Check eligibility for EI special benefits and Quebec parental-insurance rules separately. Self-employment does not provide ordinary employee unemployment coverage.
• Set aside cash for tax payments and check instalment requirements. Filing and payment deadlines are different questions.
• Use your CRA RRSP deduction-limit statement; earned income, annual limits and adjustments affect new room.

Some services supplied to non-resident clients qualify as zero-rated exports for GST/HST, but not every invoice to a US address qualifies. The service type, recipient and statutory exclusions matter. Advisory and professional services have specific provisions.

For an ordinary business, the $30,000 small-supplier test includes worldwide taxable supplies, including zero-rated supplies, and associated persons where applicable. Check both a single calendar quarter and consecutive-quarter totals. The registration effective date depends on how the threshold is exceeded.

Voluntary GST/HST registration can allow eligible input tax credits, but also creates filing and recordkeeping obligations. It does not make every personal or business purchase fully recoverable. Check Quebec sales-tax obligations separately where relevant.

Services physically performed in the US can create US-source employment income and filing obligations. Track workdays and travel dates. Treaty relief depends on conditions such as remuneration, presence and who bears the employment cost; a short trip is not automatically exempt.

Federal treaty relief does not settle every state-tax question. Stock compensation, bonuses and other payments may also need allocation across work locations and periods.

• Confirm provincial health-plan eligibility and coverage for time outside Canada.
• Read the employer plan's actual geographic coverage, eligibility and exclusions for health, dental, disability and life insurance.
• Compare any paid leave, pension or savings match with what a business contract provides.
• Keep a cash buffer for unpaid time and income interruptions.
• Check exchange-rate and conversion costs if the pay is in US dollars.

Do not assume that a US retirement plan is always unavailable or always tax-efficient for a Canadian resident. Plan eligibility and treaty relief depend on the circumstances. CRA has separate rules and forms for eligible cross-border commuters and temporary assignments; get advice before contributing or withdrawing.

Incorporation does not turn an employee-like relationship into an independent business. Personal services business (PSB) rules can apply where a worker would reasonably be an employee of the client without the corporation and the other statutory conditions are met.

The CRA also considers specified-shareholder status, the corporation's full-time employee count and whether the payer is an associated corporation. One client does not automatically establish a PSB, and several clients do not automatically prevent one.

A PSB loses access to certain corporate tax reductions and has restricted deductions. A corporation outside the PSB rules is not automatically entitled to the small business deduction either. Residency, control, income type and other limits matter.

• Tax residency: the status that determines how each country taxes you, subject to applicable treaty rules.
• Certificate of coverage: evidence of the social-security system covering the work under an agreement.
• Zero-rated supply: a taxable supply charged at a zero GST/HST rate; it is different from an exempt supply.
• Employer of record: the entity that legally employs the worker under the arrangement.
• Keep contracts, payroll slips, invoices, travel records, exchange-rate records and coverage certificates.
