Quick Answer

> One line summary: California's tax system includes state income tax, sales tax, property tax, and various business taxes, each with distinct rules and rates that differ from other states.

What is the California tax system and how does it work?

California's tax system is a combination of state-level taxes administered by the California Department of Tax and Fee Administration (CDTFA) and the Franchise Tax Board (FTB). The system includes personal income tax, corporate income tax, sales and use tax, property tax, and various excise taxes. Unlike some states, California has a progressive income tax structure, meaning higher earners pay a larger percentage of their income in taxes.

The state income tax rates range from 1% to 13.3% for individuals, with the highest rate applying to income over $1 million. Sales tax rates vary by location, with a base rate of 7.25% plus local add-ons that can bring the total to over 10% in some cities. Property tax is governed by Proposition 13, which limits annual increases to 2% and caps the rate at 1% of the assessed value.

How does California state income tax work for residents and non-residents?

California taxes residents on all income, regardless of where it is earned. Non-residents are taxed only on income derived from California sources. The state uses a progressive tax system with nine brackets for 2024: 1%, 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3%, and 12.3% for income over certain thresholds. An additional 1% surcharge applies to income over $1 million, making the top rate 13.3%.

Residents must file a California tax return if their gross income exceeds certain thresholds, which are lower than federal filing requirements. The standard deduction for 2024 is $5,540 for single filers and $11,080 for married couples filing jointly. California does not conform to all federal tax rules, particularly regarding deductions for state and local taxes (SALT) and certain business expenses.

How does California sales tax work and what are the rates?

California's sales tax is a transaction tax imposed on the sale of tangible personal property. The base state rate is 7.25%, which includes 6% state sales tax, 0.25% local tax, and 1% Bradley-Burns tax. Local jurisdictions can add additional taxes, resulting in combined rates ranging from 7.25% to 10.75% in some areas.

The tax applies to most retail sales of goods, including furniture, electronics, clothing, and vehicles. Some items are exempt, such as most food for home consumption, prescription medicines, and certain medical devices. Services are generally not subject to sales tax, though some services like repair and installation may be taxable if they involve tangible property.

How does California property tax work under Proposition 13?

California property tax is governed by Proposition 13, passed in 1978, which limits property taxes to 1% of the assessed value at the time of purchase. Annual increases in assessed value are capped at 2%, regardless of market appreciation. When a property is sold, it is reassessed at the current market value, which can result in a significant tax increase for the new owner.

The tax applies to real property, including land and buildings. Personal property used in business, such as equipment and machinery, is also subject to property tax. Exemptions include the homeowner's exemption (up to $7,000 of assessed value) and exemptions for certain types of property like churches and charitable organizations.

How does California business tax work for different business structures?

California imposes several taxes on businesses, including the corporate income tax, the minimum franchise tax, and the LLC fee. The corporate income tax rate is 8.84% for most corporations, with a minimum franchise tax of $800 per year. S corporations pay a 1.5% tax on net income, with a minimum of $800.

Limited liability companies (LLCs) are subject to an annual tax of $800 plus a gross receipts fee that ranges from $0 to $11,790, depending on total income. Sole proprietorships and partnerships are not subject to the $800 minimum tax but must pay state income tax on their profits. All businesses must register with the Secretary of State and obtain necessary permits and licenses.
