If you’ve been following the news lately, you’ve likely seen the headlines about a "tax blitz" coming to California in 2026. While some of these measures are aimed at the ultra-wealthy, the underlying shift in California’s tax policy has implications for almost every resident and business owner in the state.
At JMDL Tax Solutions, we are closely monitoring these legislative shifts to ensure our clients are not caught off guard. Here is the breakdown of the three major "pillars" of the 2026 tax landscape.
1. The 2026 Billionaire Tax Act: More Than Just a Headline
The most talked-about proposal is a ballot initiative for November 2026 that seeks to impose a one-time 5% wealth tax on residents with a net worth exceeding $1 billion.
The Structure: The tax would be based on worldwide net worth as of December 31, 2026.
The Controversy: Beyond the high rate, the act includes "exit tax" style provisions. If a resident was in California on January 1, 2026, they could still be subject to the tax even if they move before the end of the year.
Why it matters to you: Even if you aren't a billionaire, this measure signifies a move toward taxing assets rather than just income. Many tax experts worry that if this passes, the threshold could be lowered in future years to target the broader "millionaire" class or home equity.
2. The "Mileage Tax" and the End of Cheap Commutes
With gas tax revenues declining due to the rise of Electric Vehicles (EVs), California is moving forward with a Road User Charge (RUC).
The Pilot Phase: Following a successful pilot program that ended in early 2025, the state is considering a fee of roughly 2.8 to 5 cents per mile driven.
The Business Impact: For companies with a mobile workforce (sales, delivery, field services), this is effectively a new payroll or operational expense. Under California Labor Code 2802, employers will likely be required to reimburse employees for this tax, adding a significant layer of administrative and financial burden.
3. Healthcare Costs and the MCO Tax Extension
California is facing a massive budget shortfall for Medi-Cal. To plug this hole, the state has extended the Managed Care Organization (MCO) Tax through the end of 2026.
The Result: While this is a tax on insurers, history shows these costs are almost always passed down. Combined with the expiration of federal health insurance subsidies, many Californians are looking at double-digit premium increases starting in 2026.
