California Just Killed a 30-Year Tax Break — Your Software Bill Rises January 1

If your business runs on QuickBooks, Salesforce, a scheduling app, or basically any software you access through a browser instead of installing from a disc, California just changed the math on what you pay for it. Governor Gavin Newsom signed SB 122 on June 29, 2026, ending a policy quirk that let most electronically delivered software and cloud subscriptions dodge sales tax in the state for more than three decades. Starting January 1, 2027, that exemption is gone.

For a small business paying for a stack of SaaS tools — accounting software, point-of-sale systems, payroll platforms, project management apps — this isn't a rounding error. It's a new line item that shows up every month, on every renewal, for as long as you're in business in California.

Why California Software Was Untaxed in the First Place

Since the early 1990s, California's tax code drew a strange line: software you bought on a physical disc or downloaded as a one-time purchase could be taxed, but software delivered electronically or accessed remotely through the cloud generally was not. That distinction made sense when most software still shipped in a box. It made much less sense by 2026, when almost no small business buys software that way anymore.

SB 122 closes that gap. The law expands California's sales and use tax to cover "digital products," which includes prewritten computer software delivered electronically and Software-as-a-Service accessed remotely — regardless of how it reaches the buyer. Custom-built software developed specifically for one client remains exempt, but off-the-shelf SaaS tools do not.

What This Actually Costs You

Once the law takes effect, California's statewide base sales tax rate of 7.25% will apply to covered software purchases, plus whatever local district tax applies where the buyer is located. In cities with higher district add-ons, the combined rate can run close to 10.75%. On a $500-a-month software stack, that's an extra $35 to $54 a month — not dramatic on its own, but it adds up fast once you count every subscription a modern small business runs: point-of-sale, payroll, accounting, scheduling, email marketing, e-commerce, and more.

The state's own estimates put the scale of this in perspective: California projects the change will bring in roughly $900 million a year to the general fund and another $1.1 billion annually in local sales tax revenue, for a combined haul of around $2 billion a year. That revenue has to come from somewhere, and for most affected businesses, it's coming out of the software budget.

Who Actually Has to Deal With This

Two different groups of business owners need to pay attention, for two different reasons.

If you buy software

Any California-based business that subscribes to SaaS tools should expect vendors to start adding sales tax to invoices beginning with the first billing cycle in 2027. If you're budgeting for next year, this is the moment to build that extra percentage into your numbers rather than getting surprised by it on a January invoice. It's worth revisiting your profit and loss statement now so the new expense doesn't quietly eat into margins you were counting on.

If you sell software

If you run a SaaS company or sell any prewritten software to California customers, the obligation shifts to you. You'll likely need to register with the California Department of Tax and Fee Administration (CDTFA), determine where your customers are located for tax purposes, and start collecting and remitting sales tax on covered transactions. CDTFA has been holding public workshops throughout the summer to clarify how the rules apply to bundled products, free trials, and multi-state customers — worth monitoring if your business model doesn't fit neatly into "one software product, one price."

A Small Consolation: Lower Franchise Tax for New Entities

SB 122 wasn't purely a revenue grab aimed at software. Tucked into the same legislation is a temporary break for new businesses: the annual minimum franchise tax for newly formed pass-through entities drops from $800 to $400 for tax years 2027 through 2029. If you've been putting off registering your company or are weighing your options between an LLC formation and other structures, that's a modest but real reduction in your first few years of fixed costs. It's also a good moment to revisit the LLC vs. S corp decision if your business has grown since you first set up your entity, since the tax treatment differences compound over time.

Key Dates to Put on Your Calendar

• June 29, 2026 — SB 122 signed into law by Governor Newsom.
• Through late 2026 — CDTFA workshops and guidance continue to clarify implementation details.
• January 1, 2027 — Sales and use tax on covered digital products and SaaS takes effect statewide.
• 2027–2029 — Reduced $400 minimum franchise tax available to newly formed pass-through entities.

What to Do Before January 1

A few practical steps make sense regardless of which side of this you're on:

• Audit your software stack. List every SaaS subscription your business pays for and estimate the added tax cost at your local combined rate.
• Ask your vendors directly. Larger software companies will likely update their invoicing automatically, but smaller or niche vendors may not have systems in place yet — ask now rather than finding out in January.
• If you sell software, talk to a tax professional. Registration and collection requirements vary based on where your customers are and how your product is bundled or priced.
• Rebuild your 2027 budget with the new rate baked in. Even a few percentage points across a dozen subscriptions adds up over twelve months.

California hasn't taxed cloud software for over 30 years. Come January, that era ends, and for small businesses running on a growing stack of digital tools, it's one more cost to plan for rather than discover after the fact.
