For software and SaaS companies

Your software is taxable in some states, not others

Whether SaaS is even subject to sales tax depends entirely on the state, and the map is a patchwork. You only collect where your software is taxable and you have nexus, both at once. We map that intersection for you, form the entity investors expect, and lock down your IP from day one.

The tax question with no single answer

Is SaaS taxable? It depends on the state

There is no national rule for software. One state taxes your subscription in full, the next exempts it, and a third only taxes it if a customer downloads something or uses it for business rather than personal use. Sell into fifty states and you are quietly making fifty different decisions, most of them without realizing it.

We turn that patchwork into a clear map. Your product's taxability is checked against each state's current rules, and layered against where you actually have nexus, so you collect in exactly the states where both are true, and nowhere that you should not.

Taxability guessed
  • Charging tax where SaaS is exempt
  • Not charging where it is taxable
  • Economic nexus crossed unnoticed
  • IP never assigned by a contractor
  • A state audit years into growth

  • Taxability checked per state
  • Collecting only where both apply
  • Economic nexus tracked as you grow
  • IP assigned from the first commit
  • Audit-ready records the whole way
When do you actually collect?

Two conditions, one answer

You collect sales tax on SaaS only when your software is taxable in a state and you have nexus there. Set both and see where a state lands.

Your SaaS is taxable here and you have nexus, so you register and collect sales tax in this state. We set up the collection and file the returns.
Taxability rules and thresholds change, and vary by product and customer type. We keep the current rules mapped to each state for you. See sales tax registration.
How your SaaS company gets set up

From first commit to collecting correctly

Five steps, in the right order. Select one to see the detail.

Step 1

Form the entity investors expect

If you plan to raise venture capital, that means a Delaware C-corp, which the standard financing documents assume. If you are bootstrapping, an LLC is simpler and can convert later. We form the right one, with state fees passed through at cost.

Entity: DE C-CORP
Financing-ready structure
EIN in progress
Step 2

Get your EIN and lock down your IP

The EIN is your federal tax ID, and IP assignment is what makes the company, rather than an individual founder or contractor, the owner of the code. We make sure every contributor assigns their work, and help register copyright, which is exactly what diligence checks.

Step 3

Map where your software is taxable

We check your specific product against each state's SaaS rules, since some tax it, some exempt it, and some only tax it for business use or when downloaded. Then we layer that against where you have nexus, so you know exactly which states require collection.

Step 4

Register and collect where both are true

In each state where your SaaS is taxable and you have nexus, we register for a sales tax permit and set up collection so the right tax is charged on your invoices and subscriptions. Nowhere your product is exempt, and nowhere you lack nexus.

Permits and collection only where you actually owe. Registration.

Step 5

File the returns, and track the changes

We file your sales tax returns and watch what moves: new economic nexus as you grow, states that change how they tax SaaS, and your equity milestones like a 409A when you raise. The map stays current instead of going stale the moment you set it.

Returns filed, rule and nexus changes caught in the calendar.

How this compares for a SaaS company

Entity, IP, and tax, not just one

Most tools handle the sales tax engine and leave the entity and IP to you. Here is the difference.

The honest version. At real scale a dedicated tax engine and an accountant are worth having, and nothing here is tax advice. What File.Business does is connect the entity, the IP, and the taxability-plus-nexus map in one place, so a software company is not stitching formation, equity, and sales tax across three vendors that never talk. Compare on the comparison hub.

Do I charge sales tax on my SaaS subscriptions?

In some states, not others. Roughly 25 jurisdictions tax SaaS, and a handful more tax it only when software is downloaded, while others exempt it. You collect only where your product is taxable and you have nexus. Right now that overlap is nine states, and I have you registered in each.

I just signed customers in Texas and California. Same treatment?

No. In Texas SaaS is taxable, so if you have nexus there you collect. California generally does not tax SaaS, so you would not, even with nexus, unless it is bundled with something tangible. I have Texas set to collect and California set to exempt on your invoices.

We are raising a seed round. Anything I am missing?

Two things diligence will check. Your IP assignments, so the company owns all its code, which you have, and a 409A before you grant options, which I can start now. Your Delaware C-corp and cap table are already in order. See funded startups.
From a SaaS founder

We were collecting tax in the wrong states

We had been charging sales tax everywhere, to be safe, and it turned out we were charging it in states where our software was exempt and missing a few where it was taxable. File.Business mapped our actual taxability against our nexus, fixed the collection state by state, and cleaned up the entity and IP before our round. Diligence did not find a thing.

For the questions software teams actually ask

Straight answers on SaaS tax, entity, and IP

Is my SaaS subject to sales tax?
It depends on the state. Roughly 25 US jurisdictions tax some form of SaaS, and about seven more tax it only when software is downloaded, while others exempt it entirely. Some even treat it differently for business versus personal use. There is no single national rule, which is why we check your product against each state's current position.
So where do I actually collect?
Only in states where two things are both true: your software is taxable there, and you have nexus there. If a state exempts SaaS, you do not collect even with nexus. If a state taxes SaaS but you have no nexus yet, you do not collect until you cross the threshold. We map the overlap and register you only where you owe.
Does economic nexus apply to SaaS?
Yes. Since the Wayfair decision, selling enough into a state creates economic nexus even with no physical presence, commonly around 100,000 in annual sales. For SaaS, nexus is only half the test: once you have it, the state's taxability rule decides whether you actually collect. We track both. See sales tax registration.
What entity should a SaaS startup use?
If you plan to raise venture capital, a Delaware C-corp, which investors expect and the standard financing documents assume. If you are bootstrapping, an LLC is simpler and can convert later. We help you match the entity to your funding path and form it cleanly. See founders.
How do I protect my IP?
Every founder, employee, and contractor should assign their work to the company, or the company may not actually own its own code, which investors scrutinize in diligence. You can also register copyright for the software and a trademark for the product name. We put the assignments in place from the first contributor. See copyright registration.
Customers in Texas versus California, same rules?
No. Texas taxes SaaS, so with nexus there you collect. California generally does not tax SaaS, so you would not, unless it is bundled with something tangible like hardware. This is exactly the kind of state-by-state difference we map, so your invoices charge the right amount in each place.
What about 409A valuations and options?
Once you raise or start granting stock options, you need a 409A valuation to set a defensible strike price, and a priced round is a material event that resets it. We keep your cap table and 409A ready alongside the tax work, so equity and compliance move together. See funded startups.
Does this replace my tax engine or accountant?
No, and this is not tax advice. At high volume a dedicated tax engine and an accountant are worth having. File.Business handles the entity, the IP, the registrations, and the returns, and maps taxability to nexus, so the foundation is right and your other tools plug into a clean setup. Talk to us.
