Do You Need to Charge Sales Tax?
Understanding when you need to:
General Rule
You must charge sales tax if:
- You have "nexus" in a state
- You sell taxable goods or services in that state
- State requires collection
Most service providers: Don't need to charge sales tax (services often exempt)
Product sellers: Usually need to charge sales tax (if have nexus)
Service Providers
Most professional services (consulting, design, writing, etc.):
- Usually exempt from sales tax in most states
- Don't need to charge sales tax
Examples of exempt services:
- Consulting
- Design services
- Writing, editing
- Programming, development
- Most professional services
But: Check your state (some states do tax services)
Product Sellers
If you sell physical products:
- Usually taxable in all states (if you have nexus)
- Must charge sales tax
Examples:
- Etsy sellers
- Amazon sellers
- Physical product sales
Understanding Sales Tax Nexus
This determines if you must collect:
What Is Nexus?
Nexus = Connection to a state that requires you to collect sales tax
Two types:
- Physical nexus
- Economic nexus
Physical Nexus
You have physical nexus if:
- You have office/warehouse in state
- You have employees in state
- You store inventory in state
- You have other physical presence
Most freelancers: Don't have physical nexus (work from home, no physical presence in other states)
Economic Nexus
You have economic nexus if:
- You exceed sales threshold in state
- Usually $100,000+ in sales OR 200+ transactions
- Varies by state
Most freelancers: Don't have economic nexus (sales below thresholds)
Real Nexus Example
Scenario: Freelance designer, works from home in California
Sales: $50,000/year to clients in various states Physical presence: Only in California Economic nexus: $50,000 < $100,000 threshold
Result: No sales tax collection required (no nexus, services exempt)
Services vs. Products
Understanding the difference:
Services (Usually Exempt)
Most professional services:
- Consulting
- Design
- Writing
- Programming
- Usually exempt from sales tax
Most freelancers: Provide services, so don't need to charge sales tax
Products (Usually Taxable)
Physical products:
- Goods you sell
- Usually taxable (if you have nexus)
If you sell products: Usually need to charge sales tax
Digital Products (Varies)
Digital products (courses, software, etc.):
- Varies by state
- Some states tax, some don't
- Complex rules
Check your state's rules for digital products
How to Add Sales Tax to Invoices
If you need to charge it:
Method 1: Add Tax to Price
How it works:
- Service: $1,000
- Sales tax (8%): +$80
- Total: $1,080
Customer pays: $1,080 Your income: $1,000 (not $1,080) Sales tax: $80 (you collect and remit)
Method 2: Include Tax in Price
How it works:
- Price: $1,080 (includes tax)
- Sales tax portion: $80
- Your income: $1,000
Less common: Usually add tax separately
Best Practice
Add tax separately (Method 1):
- Shows customer what they're paying for tax
- Clearer
- Easier accounting
Example invoice:
Services: $1,000.00
Sales tax (8%): $ 80.00
Total: $1,080.00
State Registration Requirements
If you must collect sales tax:
Register with State
Before collecting, you must:
- Register for sales tax permit with state
- Get sales tax ID number
- File returns (usually quarterly or monthly)
How to register: State's revenue/tax department website
Ongoing Requirements
After registering:
- Collect sales tax on taxable sales
- File returns (quarterly or monthly, varies by state)
- Remit sales tax collected
- Keep records

Remitting Sales Tax
How to handle it:
When to Remit
Usually:
- Quarterly (most common)
- Monthly (if sales are high)
- Annually (if sales are very low)
Varies by state: Check your state's requirements
How to Remit
Options:
- Online (state's website)
- By mail (with check)
- Through tax software
Keep records: Of all sales tax collected and remitted
What Happens If You Don't Remit
Penalties: States assess penalties for not remitting
Taxable income: If you collect but don't remit, it becomes taxable income
Don't do this: Always remit sales tax you collect
Real Examples and Scenarios
Let's work through scenarios:
Example 1: Service Provider, No Sales Tax

Your income: $500 (not $536.25) Sales tax: $36.25 (collect and remit)
Example 3: Mixed Services and Products
Scenario: Freelancer sells both
