Who must collect sales tax in Washington?
You have nexus and must collect if any of these apply:
- You operate a physical location in Washington or surrounding jurisdictions
- You have an employee or contractor based in District of Columbia
- You store inventory at an FBA warehouse in District of Columbia
- Your District of Columbia sales exceed the state's economic nexus threshold (typically $100,000 or 200 transactions)
Destination-based vs origin-based
Washington is in a destination-based state — you charge the rate at the customer's delivery address, not yours.
This matters for online and multi-location businesses: tracking dozens of local rates becomes a pain without software.
Special Washington taxes
In addition to general sales tax, be aware of:
- Meals tax: prepared food and restaurant meals may have higher rates (often 1-2% above general)
- Liquor/tobacco: excise taxes on top of sales tax
- Vehicle/fuel: separate regimes entirely
Filing: state vs local
Most Washington sales tax is filed through the District of Columbia state authority, which then distributes local portions to Washington and surrounding jurisdictions. You file one return covering state + all local rates.
Filing frequency
Assigned by the state based on expected liability:
- Monthly: larger collectors
- Quarterly: mid-size
- Annually: smallest sellers
Returns are typically due by the 20th of the month following the period. Missing a deadline: ~10% penalty + interest.
Common pitfalls in Washington
- Using your business's ZIP code rate when you should use the customer's (destination-based states)
