California's New SaaS Tax: What It Means for Your POS Software Bill

Will California start taxing my POS software subscription?

Yes. Starting January 1, 2027, California will apply sales tax to prewritten software delivered electronically or accessed remotely, which includes cloud-based point-of-sale software, payment add-ons, and most SaaS subscriptions a merchant pays for monthly.

Governor Newsom signed SB 122 on June 29, 2026. Until now, California has mostly stuck to an older rule: software delivered on a disk or downloaded was taxable tangible personal property, but software accessed remotely or delivered purely electronically usually wasn’t. SB 122 closes that gap. It rewrites the definition of taxable “tangible personal property” to reach prewritten software regardless of how it’s delivered, whether on physical media, downloaded, or accessed through the cloud. SaaS falls under that umbrella.

What’s actually taxable, and what isn’t

The law targets prewritten (off-the-shelf) software. Custom software built specifically for a business stays exempt, as it has been. Other digital products, like ebooks, streaming music, and video, are also staying exempt under this bill; the legislature drew the line specifically around software.

For a merchant, that means the monthly fee for your POS platform, a reporting add-on, an online ordering module, or a scheduling tool are the kinds of charges likely to pick up sales tax starting in 2027, if that software counts as prewritten and is used in California. If you’re paying for software that was built just for your business from scratch, that part should stay untaxed, but very few small merchants are in that situation; almost everyone is on an off-the-shelf SaaS product.

The standard California state rate is 7.25%, and local district taxes stack on top of that depending on your city and county, the same way they do on a restaurant check or a retail sale. So the tax on a software bill won’t be a flat number statewide; it depends on where you’re billed from.

When does the tax actually kick in on my contract?

This is the part worth paying attention to if you lock in annual software contracts. The California Department of Tax and Fee Administration (CDTFA) has said that taxability generally depends on when the right to access the software transfers, not simply when you’re invoiced. Practically, that raises a real question for anyone who signs or renews a fixed-term software contract late in 2026: a contract that grants a fixed right of access before January 1, 2027 may be treated differently than one renewed or newly granted after that date.

If you’re due for a POS software renewal around the end of this year, that timing question is worth a direct call to your software provider’s billing team, not a guess. The CDTFA was still working through implementation details as of fall 2026: it held a second interested-parties meeting on September 10, 2026, and set a public comment deadline of September 24, 2026, on its proposed emergency regulations. Some administrative specifics, like how sourcing works for a business billed across multiple locations, hadn’t been finalized as of this writing.

What this doesn’t change

This tax doesn’t touch your card processing rates, interchange, or the hardware itself if you bought your terminal outright rather than renting it. It’s specifically about the software layer: cloud POS platforms, software-as-a-service tools, and similar subscriptions. If your Clover plan includes software modules billed monthly, those are the charges to watch; the physical terminal you already own isn’t newly taxed by this law.

What to do before January 1, 2027

A short list, not a full compliance project:

• Ask your POS or software provider directly whether your subscription will be taxed starting in 2027, and whether they’ll be the one collecting and remitting it (most SaaS vendors with a presence in California will be expected to).
• If you’re renewing or signing a multi-year software contract before year-end, ask specifically how the contract’s start date affects tax treatment under SB 122.
• Build a few extra dollars a month into your 2027 software budget. On a $100/month POS software bill, state tax alone adds about $7.25, before any local add-on.
• Don’t assume this affects your card processing statement. It’s a separate tax on the software subscription, not a change to interchange or your effective rate.

None of this needs to be solved today. But software renewal season tends to sneak up on small businesses, and a quiet year-end auto-renewal is exactly the kind of contract that could lock in one tax treatment or another depending on its date. A five-minute question to your provider now beats a surprised look at a January invoice.

This is general information, not tax or legal advice. Confirm your specific situation with your tax professional or the CDTFA.
