Focus CPA flags 2026 California tax risks for LLCs and S-corps

Focus CPA Group says California LLC and S-corporation owners face growing state and local tax compliance risks in 2026, especially around PTE taxes, Franchise Tax Board filings and reasonable salary rules. The firm says early planning can help business owners avoid penalties, back taxes and missed deductions.

Why it matters: - California LLCs and S-corporations can face state tax obligations that do not match federal tax treatment. - Missed filings, bad elections or salary mistakes can lead to penalties, interest and back taxes. - The 2026 filing window leaves less room to fix problems late in the year.

What happened: - Focus CPA Group, led by Amit Chandel, CPA and LLM (Tax), warned California LLC and S-corporation owners about state and local tax compliance risks heading into the final months of 2026. - The firm said many business owners do not fully understand filing requirements, pass-through entity tax obligations and California-specific deadlines. - Focus CPA said the SALT cap remains at $40,000 through 2029, making proactive planning more important.

The details: - California LLCs and S-corporations face state income tax rules, franchise tax filings and entity-level taxes that operate separately from federal tax treatment. - California's pass-through entity tax can apply to certain entities and can change overall tax liability. - Business owners need to know whether their structure qualifies for PTE tax elections and compliance rules. - The federal SALT cap limits deductions for state and local taxes, while California has reciprocal rules that affect deduction planning. - Franchise Tax Board filings are required separately from federal returns, and missed deadlines can trigger audits and penalties over multiple years. - S-corporations must pay owners a reasonable salary subject to employment taxes. - The IRS and California Department of Tax and Fee Administration scrutinize S-corporations that understate owner pay. - Improper salary treatment can lead to reclassification of distributions and back taxes at both the federal and state level. - Businesses with multiple LLCs or property held through separate entities face additional coordination demands under California's stacking rules. - Focus CPA said national firms often treat California compliance as a lower priority and miss state-specific risks and opportunities. - Amit Chandel said business structures optimized for federal taxes can create California compliance problems if they are not managed correctly. - Chandel also said California pass-through entity taxes can cause business owners to pay twice if the structure is not set up properly. - Chandel said some owners only hire a California State Tax CPA after they have already created a problem.

Between the lines: - California tax planning is becoming more specialized as state and federal rules diverge. - The warning reflects a broader shift toward entity-level planning, not just individual tax filing. - Business owners that wait until filing season may have fewer options to correct structure or compensation issues.

What's next: - Focus CPA says early-year corrections and adjustments can reduce year-end surprises. - The firm is offering SALT compliance strategies for California LLCs and S-corporations. - Focus CPA is also advising on entity structure reviews and SALT deduction strategies aimed at staying compliant while reducing taxes legally. - More information is available through the firm's social media pages, including LinkedIn, Facebook and X.

The bottom line: - For California LLCs and S-corporations, 2026 tax planning is less about routine filing and more about avoiding state-specific compliance traps before they become expensive.
