Understanding the Fundamental Difference
This is critical:
Sales Tax vs. Income Tax
Sales tax:
- Collected from customers
- Remitted to states
- Based on sales (what you sell)
- Not your money (you're just collecting it)
Income tax:
- Paid by you
- Paid to federal and state governments
- Based on profit (income minus expenses)
- Your money (tax on your earnings)
The Key Point
They're completely separate:
- Sales tax doesn't affect your income tax (usually)
- Income tax doesn't affect sales tax
- You handle them separately
Exception: If you don't remit sales tax you collected, it becomes taxable income
What Is Sales Tax?
Understanding sales tax:
Definition
Sales tax = Tax on the sale of goods or services, collected from customers and remitted to states
How it works:
- You charge customers sales tax (added to price)
- You collect it from them
- You remit it to state(s)
- It's not your money - you're just the collector
Who Pays Sales Tax?
Customers pay sales tax (you collect it from them)
You remit sales tax to states (you're the collector, not the payer)
What's Subject to Sales Tax?
Varies by state, but typically:
- Tangible goods: Usually taxable
- Services: Varies by state (some tax services, some don't)
- Digital products: Varies by state
Most states: Tax goods, some tax services
Service providers: May or may not need to collect sales tax (depends on state)
What Is Income Tax?
Understanding income tax:
Definition
Income tax = Tax on your profit (income minus expenses)
How it works:
- You report all income
- You deduct business expenses
- You pay tax on profit
- It's your money - you're the payer
Who Pays Income Tax?
You pay income tax (on your profit)
You also pay self-employment tax (15.3% on net income)
What's Subject to Income Tax?
All income is subject to income tax:
- Income from sales
- Income from services
- Investment income
- All income (unless excluded by specific provisions)
When Do Freelancers Collect Sales Tax?
Understanding when you need to collect:
General Rule
You must collect sales tax if:
- You have "nexus" in a state
- You sell taxable goods or services in that state
- State requires collection
Most freelancers: May not need to collect sales tax (depends on what you sell and where)
Service Providers
Most service providers (consultants, designers, writers, etc.):
- Don't need to collect sales tax in most states
- Services are often exempt from sales tax
- But: Check your state's rules (some states do tax services)
Examples of states that tax services:
- Hawaii: Taxes many services
- New Mexico: Taxes most services
- South Dakota: Taxes many services
- Most states: Don't tax professional services
Product Sellers
If you sell products (physical goods):
- Usually need to collect sales tax (if you have nexus)
- Products are usually taxable
- Must register with state, collect, and remit
Example: Etsy seller, Amazon seller, etc.
- Usually need to collect sales tax (if have nexus)
Digital Products
If you sell digital products (courses, software, etc.):
- Varies by state
- Some states tax digital products
- Some states don't
- Complex rules - check each state
Sales Tax Nexus Rules
Understanding nexus:
What Is Nexus?
Nexus = Connection to a state that requires you to collect sales tax
Two types:
- Physical nexus: Physical presence in state (office, warehouse, employees, etc.)
- Economic nexus: Exceed sales threshold (usually $100,000+ or 200+ transactions)
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 (home office) Economic nexus: $50,000 < $100,000 threshold in any state
Result: No sales tax collection required (no nexus in other states, services may not be taxable anyway)

How Sales Tax Affects Income Tax
Understanding the interaction:
Sales Tax Collected Is Not Income
Key point: Sales tax you collect from customers is not your income
How it works:
- You charge customer $1,000 + $80 sales tax = $1,080 total
- Your income: $1,000 (not $1,080)
- Sales tax: $80 (you collect and remit, not your money)
On tax return:
- Report income: $1,000
- Don't report sales tax collected as income
- Remit sales tax separately to state
If You Don't Remit Sales Tax
If you collect sales tax but don't remit it:
- It becomes taxable income
- You must report it as income
- Pay income tax on it
- Plus: Penalties for not remitting
Example: Collected $5,000 in sales tax, didn't remit
- Must report $5,000 as income
- Pay income tax on $5,000
- Plus: Penalties for not remitting
Don't do this: Always remit sales tax you collect
Sales Tax Paid on Purchases
If you pay sales tax on business purchases:
- It's part of the purchase price
- Deductible as business expense (included in cost of goods/services)
Example: Buy $1,000 computer, pay $80 sales tax
- Total cost: $1,080
- Deduct: $1,080 (includes sales tax)
State-Specific Sales Tax Rules
Understanding state variations:
States That Don't Tax Services
Most states: Don't tax professional services
Examples:
- California: Services generally not taxable
- New York: Services generally not taxable
- Texas: Services generally not taxable
- Most states: Services exempt
Most freelancers: Don't need to collect sales tax (if providing services)
States That Tax Services
Some states: Do tax services
Examples:
- Hawaii: Taxes many services
- New Mexico: Taxes most services
- South Dakota: Taxes many services
- Washington: Taxes some services
If you're in these states: May need to collect sales tax on services
Product Sales
If you sell products:
- Usually taxable in all states (if you have nexus)
- Must register, collect, and remit
Example: Online seller
- Usually need to collect sales tax (if have nexus)
Real Examples and Scenarios
Let's work through scenarios:
Example 1: Service Provider, No Sales Tax
Scenario: Freelance consultant, California
Services: Consulting (not taxable in California) Sales: $80,000/year Nexus: Only in California
Sales tax: Don't need to collect (services not taxable, no nexus elsewhere)
Income tax: Pay income tax on $80,000 profit (after expenses)
Example 2: Product Seller, Needs Sales Tax
Scenario: Online seller, California
Products: Physical goods (taxable) Sales: $150,000/year Nexus: California + economic nexus in 5 other states
Sales tax: Must collect in California + 5 other states (register, collect, remit)
Income tax: Pay income tax on $150,000 profit (sales tax collected is not income)
Example 3: Mixed Services and Products
Scenario: Freelancer sells both services and products
Services: $60,000 (not taxable) Products: $40,000 (taxable, if have nexus) Total: $100,000
Sales tax: Collect on $40,000 in products (if have nexus) Income tax: Pay income tax on $100,000 profit (both services and products are income)

Final Thought
Sales tax and income tax are completely different, but many freelancers confuse them. The key is understanding that sales tax is collected from customers and remitted to states (not your income), while income tax is what you pay on your profit. Most service-based freelancers don't need to collect sales tax, but product sellers usually do. Understand your obligations, collect and remit sales tax if required, and pay income tax on your profit. Do this, and you'll stay compliant with both types of taxes.
