SaaS taxation varies wildly by state. Some tax it, some don't, and the rules change constantly. Here's how to stay compliant without losing your mind.

Sales tax compliance is one of the most overlooked areas for SaaS startups. The rules are complex, vary by state, and the penalties for non-compliance can be severe.

## The Basics: Nexus

"Nexus" is the legal term for having a sufficient connection to a state that requires you to collect and remit sales tax. There are two types:

### Physical Nexus
Having a physical presence in a state:
- Office or warehouse
- Employees working in the state
- Inventory stored in the state

### Economic Nexus
Exceeding revenue or transaction thresholds in a state (post-Wayfair):
- Most states: $100,000 in revenue OR 200 transactions
- Some states have different thresholds
- Many states count gross revenue, not just taxable sales

## SaaS Taxability by State

SaaS is taxed differently across states:

### States That Tax SaaS
New York, Texas, Pennsylvania, Washington, Ohio, Connecticut, and many others

### States That Don't Tax SaaS
California, Colorado, Florida (as of recent changes), Virginia, and others

### It's Complicated
Several states have partial or conditional taxability based on:
- How the software is delivered
- Whether it's customized
- The type of customer (B2B vs. B2C)
- Whether it includes tangible personal property

## Compliance Steps

1. **Determine where you have nexus**: Map your physical and economic connections
2. **Identify taxability**: For each nexus state, determine if SaaS is taxable
3. **Register for permits**: Apply for sales tax permits in applicable states
4. **Configure your billing**: Set up tax calculation in Stripe or your billing system
5. **File returns**: File returns in each state (monthly, quarterly, or annually)
6. **Maintain records**: Keep detailed records for audit purposes

## Common Mistakes

1. Ignoring sales tax entirely until you get a notice

3. Collecting tax in your home state only
4. Not registering before you start collecting
5. Filing late and incurring penalties
