Sales tax lookup
Pick a state and (optionally) enter an amount to estimate the base state tax.
The rate above is the state base rate. What a customer actually pays — and what you must collect — usually depends on more than the state alone.
State base rate vs combined rate
Most states let counties, cities, and special districts add their own sales tax on top of the state base. The result is a combined rate that varies by exact address.
- For planning and nexus decisions, the state base rate is usually enough.
- For collecting and remitting, you need rooftop-accurate combined rates.
- Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have no statewide sales tax (Alaska allows local taxes).
Origin vs destination sourcing
States are either origin-based (charge the rate where your business sits) or destination-based (charge the rate where the customer is). Most are destination-based.
For online sellers shipping across a state, this means the correct rate usually depends on the buyer's address, not yours — a common source of under- or over-collection.
When you actually have to collect
You generally must collect once you have nexus in a state:
- Physical nexus — an office, employees, or inventory (including FBA stock) in the state.
- Economic nexus — enough sales, often $100,000 or 200 transactions, though thresholds vary.
- Marketplace facilitator laws may make platforms like Amazon collect for you in some states.

Frequently asked questions
Is this the total sales tax rate?
No — it's the state base rate. Local city, county, and district taxes usually add on top, so your combined rate is often higher and depends on the exact address.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire, and Oregon have no statewide sales tax, though Alaska allows local jurisdictions to impose their own.
When do I have to collect sales tax in a state?
Generally once you have nexus — a physical presence or enough economic activity (often $100,000 in sales or 200 transactions, though thresholds vary by state).
Does Amazon collect sales tax for me?
Marketplace facilitator laws make Amazon collect and remit in many states, but not all situations are covered, so you should still confirm where you owe.
