The Party's Over: What California’s New 2027 "SaaS Tax" Means for Your Business Bottom Line
If your California business relies on Slack, QuickBooks Online, Salesforce, Zoom, or any other cloud-based software, your operating costs are about to take a mandatory jump.
On June 29, 2026, Governor Gavin Newsom signed Senate Bill 122 (SB 122) into law. This major budget trailer bill does a complete 180-degree turn on California’s decades-old tax policy: starting January 1, 2027, Software-as-a-Service (SaaS) and digital downloads will be subject to the state's full sales and use tax.
For a business with 5 to 20 employees, this isn't just a minor line item—it’s a direct hit to your cash flow and SDE (Seller's Discretionary Earnings). Here is what you need to know and how to prepare.
What Exactly is Now Taxable?
Historically, California only taxed software if it was delivered on a physical medium like a thumb drive or CD-ROM. If you downloaded it or accessed it in the cloud, it was tax-free.
Under SB 122, the delivery format no longer matters. Tangible personal property has been redefined to include "digital products". Starting in 2027, you will pay your local combined sales tax rate (which ranges from 7.25% up to 10.25% depending on your county) on:
SaaS & Cloud Subscriptions: Any remotely accessed software hosted by a vendor.
Prewritten Software Downloads: Standard off-the-shelf software downloaded electronically.
AI Tools: Subscription-based artificial intelligence platforms.
What Stays Exempt? Custom software programmed from scratch for your business remains exempt. "Digital Infrastructure" (like AWS or Microsoft Azure where you host your own code) and purely human-driven services that happen to utilize software are also excluded.
The Real Impact on Your Business Valuation
As business brokers, we look at your financials through the lens of Seller’s Discretionary Earnings (SDE). Every dollar of unnecessary overhead directly reduces your company's ultimate sale price.
If your business spends $40,000 a year on various SaaS platforms, a 9% average tax rate adds $3,600 in pure, unrecoverable annual expense.
In Main Street business acquisitions, companies are often valued at a multiple of SDE (e.g., $3.5\times$ or $4\times$).
A $3,600 reduction in SDE translates directly to a $12,600 to $14,400 drop in your business's enterprise value.
Your 3-Step Action Plan Before January 1, 2027
Map Your Tech Stack: Audit every software tool, subscription, and platform license your team currently uses.
Separate Custom Work on Invoices: If you pay developers to modify prewritten software, ensure their labor/modification fees are separately stated on invoices. Under SB 122, modifications are only exempt if billed separately; otherwise, the entire bundle could be taxed.
Adjust Your 2027 Budgets Now: Factor in an immediate 8% to 10% increase on all software procurement starting January.
