Overview
A U.S. sales tax audit for Canadian companies involves ensuring compliance with the sales tax requirements of each U.S. state where the business operates. Below are key considerations to understand:
1. Nexus Determination
Nexus refers to having sufficient physical or economic presence in a U.S. state, which obligates the company to collect sales tax from customers in that state.
Types of Nexus
- Physical Nexus: Established if the Canadian company maintains a warehouse, office, employees, or agents within the U.S. state.
- Economic Nexus: Following the South Dakota v. Wayfair ruling, nexus can be established without physical presence if sales exceed a state’s threshold (commonly $100,000 or 200 transactions annually).
2. Sales Tax Registration
If a Canadian company establishes nexus in a state, it must:
- Register with the state’s tax authority to collect sales tax.
- Obtain a sales tax permit before selling goods or services in that state.
3. Collecting and Remitting Sales Tax
Once registered, the company is responsible for:
- Collecting sales tax on taxable sales to customers in that state.
Important Considerations
- Tax Rates and Exemptions: Vary by state. Understand each state’s specific rules.
- Remittance Frequency: Sales tax must be remitted monthly, quarterly, or annually as required.
4. Recordkeeping
Maintaining accurate records is critical:
- Records of sales transactions, taxes collected, and exemptions claimed must be kept.
- States may request these records during audits to verify compliance.
- Good recordkeeping practices reduce audit liability risks.
5. Audit Triggers
An audit may be triggered by:
- Discrepancies in tax filings.
- Customer complaints.
- Significantly lower reported sales than expected.
- Random audits conducted by states to ensure compliance.
6. Audit Process
During a sales tax audit:
- The state tax authority reviews sales records, taxes collected, and filed returns.
- Audits can span multiple years.
- Discrepancies may result in penalties, interest, and back taxes owed.
7. Voluntary Disclosure Programs
If a company recognizes past non-compliance:
- Many states offer Voluntary Disclosure Agreements (VDAs) to encourage compliance.
- VDAs may reduce penalties and limit the lookback period for owed taxes.
8. State-Specific Rules
Each state has its own laws regarding:
- Nexus thresholds
- Tax rates
- Filing requirements
- Deadlines
Canadian companies must understand the rules in every state where they do business.

Summary
Canadian companies selling in the U.S. must determine whether they have nexus in any state and comply with corresponding sales tax obligations. A U.S. sales tax audit can be complex, requiring detailed records and understanding of multi-state tax laws. Proactive management, accurate recordkeeping, and state-specific compliance are key to minimizing risks during audits.
Frequently Asked Questions
What is nexus and why does it matter for Canadian businesses in the U.S.?
Nexus refers to the level of presence a business has in a U.S. state that obligates it to collect and remit sales tax. Canadian companies with physical operations (like a warehouse or employees) or significant economic activity (like $100,000 in sales) in a state may trigger nexus, requiring compliance with that state’s tax laws.
Do Canadian companies need a sales tax permit in every U.S. state?
No, only in states where the company has established nexus. If nexus exists, the business must register with the state’s tax authority and obtain a sales tax permit before making taxable sales there.
How often must sales tax be remitted?
The remittance frequency varies by state and business activity. It can be monthly, quarterly, or annually. States determine the schedule based on factors such as sales volume and filing history.
What triggers a U.S. sales tax audit?
Audits can be triggered by tax filing inconsistencies, customer complaints, underreported sales, or random selection by state tax authorities. Maintaining accurate and organized records can help reduce audit risk.
Can Canadian companies reduce penalties if they haven’t complied with tax rules?
Yes, many states offer Voluntary Disclosure Agreements (VDAs), allowing businesses to disclose past non-compliance. VDAs typically reduce penalties and limit how far back the state can audit.
