Understanding Sales Tax
Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. As a business owner, you're typically required to collect sales tax from customers and remit it to the government.
How Sales Tax Works
When you make a sale, you add the sales tax to the purchase price. The customer pays the total, and you later remit the collected tax to the state. You don't keep the sales tax - it passes through your business to the government.
Sales Tax Nexus
"Nexus" determines where you must collect sales tax. You have nexus in a state if you:
- Have a physical presence (office, warehouse, employees)
- Exceed economic thresholds (typically $100,000 in sales or 200 transactions)
- Have inventory stored in the state (including FBA warehouses)
- Attend trade shows or events in the state
State Sales Tax Rates (Base Rates)
Note: Local jurisdictions often add their own sales tax on top of state rates. Total rates can exceed 10% in some areas.
Tax-Inclusive vs Tax-Exclusive Pricing
Common Tax-Exempt Scenarios
Some transactions are exempt from sales tax:
- Sales to tax-exempt organizations (non-profits with valid exemption certificates)
- Wholesale purchases for resale
- Many professional services (accounting, legal, consulting)
- Prescription medications and medical devices (in most states)
- Groceries (in many states)
Filing and Remitting Sales Tax
After collecting sales tax, you must file returns and remit the tax to each state. Filing frequency depends on your sales volume:
- Monthly: High-volume sellers
- Quarterly: Medium-volume sellers (most common)
- Annually: Low-volume sellers
⚠️ Important: Sales tax laws are complex and vary by state. This calculator provides estimates only. Consult with a tax professional or accountant for your specific situation, especially if you sell in multiple states.
Frequently Asked Questions
Do I need to charge sales tax?
It depends on your location, your client's location, and what you're selling. Generally, you must charge sales tax if you have 'nexus' (physical or economic presence) in the state where your customer is located. Consult a tax professional for your specific situation.
What's the difference between sales tax and VAT?
Sales tax is used in the US and applied at the final point of sale. VAT (Value Added Tax) is used in most other countries and is applied at each stage of production. VAT rates are typically higher (15-25%) than US sales tax rates (4-10%).
Can I deduct sales tax I pay on business expenses?
Yes, in most cases. Sales tax paid on business purchases is typically tax-deductible as a business expense. Keep receipts showing the tax amount paid.
What if I sell to customers in multiple states?
You may need to register for sales tax in each state where you have nexus. Many states have 'economic nexus' laws requiring registration after reaching certain sales thresholds ($100,000 or 200 transactions annually).
Are digital products subject to sales tax?
It varies by state. Some states tax digital products like software and e-books, while others don't. Check your state's specific rules for digital goods and services.
