California FTB Tax Updates 2026: New Laws, PTE Changes & Filing Tips
California’s tax landscape is constantly evolving, and 2026 brings a fresh set of updates that every taxpayer, CPA, and business owner in the Golden State needs to understand. The California FTB 2026 tax updates, as published in the Franchise Tax Board’s March 2026 Tax News, cover legislative changes, new online services, and compliance reminders for the ongoing tax season. From a pivotal change in California’s conformity to the Internal Revenue Code to expanded fraud prevention tools that have saved the state over $6 billion in the last eight years, these updates affect both individual filers and businesses operating in California.
What Is SB 711 and How Does It Change California Tax Conformity for 2026? 📜
SB 711, enacted on October 1, 2025, updates California’s specified conformity date to the Internal Revenue Code — a change that determines which federal tax provisions California automatically adopts and which it does not.
California does not automatically conform to all federal tax law changes. Instead, the state uses a “specified conformity date” — a reference point in the IRC that California’s tax code is linked to. By updating this date through SB 711, California has incorporated a range of federal tax changes that were previously not reflected in state law. For tax professionals, this means carefully reviewing which new federal provisions now also apply for California purposes.
Key practical implications of the SB 711 conformity update include:
- Some federal deductions or credits that were temporarily unavailable at the California level may now be accessible for California tax purposes.
- Preparers must check whether their software and forms have been updated to reflect the new conformity date before filing 2025 California returns.
- Businesses with significant federal-state differences should conduct a fresh analysis of their California addbacks and modifications.
In our practice serving Los Angeles-area businesses, the IRC conformity date update is always a two-step process. First, we identify what changed at the federal level since the previous California conformity date. Then, we assess whether those changes are beneficial or detrimental for our California clients. SB 711’s October 2025 effective date means the 2025 California returns (filed in spring 2026) are the first returns where these conformity changes apply. We strongly recommend a proactive review before filing.
What Are the California PTE Elective Tax Add-Back Rules? 🏢
California requires an add-back of any federal deduction for Pass-Through Entity (PTE) elective tax — meaning the federal deduction taken for CA PTE tax is not allowed to reduce California income, preventing a double benefit.
California’s PTE elective tax has been a popular workaround for the federal $10,000 SALT deduction cap since its inception. Business owners of S corporations, partnerships, and LLCs taxed as partnerships have paid the California PTE tax at the entity level and received a corresponding California credit against their individual income tax.
However, under the current rules, when the PTE tax is deducted at the federal level (as an ordinary business expense), this creates a federal deduction that reduces the business’s ordinary income reported to California. The FTB’s add-back requirement means:
- The amount of federal PTE elective tax deduction must be added back to California taxable income on the California return.
- This prevents the double benefit of both deducting the tax federally and receiving a California credit for the same payment.
- Business owners receiving a K-1 from a pass-through entity should confirm their preparer is correctly handling this add-back on Schedule CA.
A frequent error is failing to add back the PTE elective tax on the California individual return when the deduction was taken at the federal partnership or S-corporation level. This can result in an understatement of California income and trigger an FTB notice or assessment. Review both the federal K-1 and the California K-1 carefully.
What Is the California Competes Tax Credit and Who Qualifies in 2026? 🌟
The California Competes Tax Credit (CCTC) is a negotiated income tax credit for businesses that want to come to California or stay and grow in California, with awards based on jobs created, wages paid, and capital investment.
The CCTC is administered by the Governor’s Office of Business and Economic Development (GO-Biz) and is available to businesses of all sizes and industries. For 2026, the CCTC application window remains an important planning opportunity for California employers. Key eligibility factors include:
- Number of full-time jobs created or retained in California
- Average wage levels relative to county average wages
- Capital investment in California operations
- Strategic importance to California’s economy
The CCTC is refundable — meaning if it exceeds your California tax liability, the excess is paid out as a refund. For growing businesses, this can represent a substantial cash benefit. We advise clients in manufacturing, technology, and healthcare industries to review CCTC eligibility annually.
What New Online Tools Is the FTB Offering for the 2026 Tax Season? 💻
The FTB launched a new “Verify Submitted Tax Return” online service in 2026, allowing taxpayers to confirm that their return has been received and is being processed — an important tool in California’s fight against identity theft and tax fraud.
California has stopped more than $6 billion in tax fraud over the last eight years — a remarkable achievement that reflects the FTB’s investment in identity verification and fraud detection technology. For taxpayers, this means occasional additional identity verification steps when filing, but also greater protection against fraudulent returns filed in their names.
Other 2026 FTB online service updates include:
- MyFTB Account Access: Enhanced 24/7 self-service options, including online Tax Information Authorization (TIA) renewals. TIA relationships last 13 months; renewals can be processed up to 90 days before expiration.
- Power of Attorney (POA) Management: POA relationships last six years. A new playlist of how-to videos on the FTB’s YouTube channel guides both taxpayers and professionals through the submission process.
- Nonresident Withholding for Property Managers: A new YouTube educational video explains California’s nonresident withholding requirements for property managers — critical for anyone managing rental properties with nonresident owners.
If you use a tax professional, make sure your Power of Attorney (POA) or Tax Information Authorization (TIA) with the FTB is current before tax season deadlines. The FTB’s faster processing through MyFTB means that submitted POA/TIA forms via the online portal are handled significantly more quickly than paper submissions. Do not wait until after a notice is issued to set up authorization.
