California lawmakers pass UK and Canada-like software tax that US 'fought' to remove

California Gov. Gavin Newsom

California Democrats have officially passed a series of tax-related proposals, sending a package to Governor Gavin Newsom that introduces a brand-new sales tax on digital software downloads.

According to a report by The New York Post, the governor is expected to sign the measures into law as part of negotiations over a broader $356 billion state budget.The report said that starting next year, the new measure will slap a sales tax on widely used digital software platforms like Slack, Google Workspace and Microsoft Suites. According to legislative analysis, the software tax is projected to bring in $900 million annually for California’s general fund.

Software tax: Rising costs and revenue impact

The report said that tech lobbying groups have fought the proposal, warning that it will stifle digital innovation and significantly increase costs for everyday businesses that rely on cloud software. Newsom acknowledged that the tax will primarily impact corporations rather than everyday consumers.“By the way, 75% of those transactions we estimate are business-to-business. 75%,” Newsom stated previously.

The tax comes at a time for cloud and SaaS giants like Microsoft and Salesforce, whose stocks have already faced market pressure over fears that generative AI tools could eventually replace traditional software services.

How California’s tax compares to the UK and Canada

The move has drawn comparisons to international “digital services taxes” that the US government has been fighting overseas. Last year, the Donald Trump administration threatened trade negotiations and retaliatory tariffs against Canada and the United Kingdom, calling such policies a “blatant attack” on American tech companies.

Canada eventually backed down and rescinded its digital tax to salvage trade talks.While Canada and the UK designed their frameworks to levy a direct percentage tax on the overall revenues earned by major US tech giants like Google, Apple, and Meta, California’s approach is structured differently.Instead of taxing a company’s total corporate revenue, California is expanding its existing retail sales tax to digital purchases to create parity between physical and online software sales.

In May, Newsom argued that the current system treats consumers unfairly based on how they shop.“As someone who lives near a Best Buy, I'm at Best Buy often. And I'm paying sales tax on a lot of this prewritten software. And then I find out that all my friends that aren't near a Best Buy, they're downloading and they are not paying sales tax. How is that fair?,” Newsom told reporters during a news conference.
