What Is CA Tax? A Complete Guide to California Taxation

CA tax generally refers to the taxes levied by the State of California on individuals, businesses, and transactions within its jurisdiction. The primary components are personal income tax, corporate income tax, sales and use tax, and property tax. Any person or entity that earns income, makes purchases, or owns property in California is subject to these taxes.

Personal income tax is administered by the Franchise Tax Board (FTB) and applies to residents and non-residents who earn income from California sources. The tax rates are progressive, ranging from 1% to 13.3% as of 2024. Residents are taxed on their worldwide income, while non-residents are taxed only on income derived from California. Businesses, including corporations and LLCs, are subject to an 8.84% corporate income tax rate, with a minimum franchise tax of $800 per year.

Sales and use tax is collected by the California Department of Tax and Fee Administration (CDTFA). The statewide base rate is 7.25%, but local jurisdictions can add additional rates, bringing the total to as high as 10.25% in some cities. Property tax is governed by Proposition 13, which caps the rate at 1% of the assessed value plus local voter-approved bonds.

For California residents, CA income tax is calculated on their total income from all sources, regardless of where the income is earned. The tax is computed using a progressive rate schedule. For the 2024 tax year, the rates are: 1% on the first $10,099 of taxable income, 2% on income between $10,099 and $23,942, and so on up to 13.3% on income over $698,271 for single filers. The standard deduction for a single filer is $5,540 in 2024.

Non-residents are taxed only on income that is derived from California sources. This includes wages earned while working in California, rental income from California property, and business income from operations within the state. Non-residents must file Form 540NR. They are not entitled to the same deductions as residents; for example, they cannot claim the standard deduction if their California-source income is less than their total income.

To calculate the tax, non-residents first compute the tax as if they were a resident on their total income, then apply the ratio of California-source income to total income. This ensures that the progressive rates are applied fairly. For example, if a non-resident has $100,000 total income but only $50,000 from California, they would pay half the tax that a resident with $100,000 income would pay.

The base CA sales tax rate is 7.25%, which consists of 6% state sales tax, 1.25% local tax, and 0.25% for the Bradley-Burns program. However, cities and counties can impose additional district taxes, known as transactions and use taxes, which can increase the total rate. As of 2024, the highest combined rate is 10.25% in cities like Alameda and Los Angeles.

The rate you pay depends on where the seller delivers the goods or where the buyer takes possession. For online purchases, the rate is based on the shipping address. The CDTFA maintains a database of all current rates by location. Businesses that sell taxable goods must collect the correct rate for each transaction.

Certain items are exempt from sales tax, including most groceries, prescription medicines, and some medical devices. Services are generally not taxed unless they involve the sale of tangible personal property. For example, a plumber's labor is not taxed, but the parts they install are. Businesses must register with the CDTFA to collect and remit sales tax.

California property tax is governed by Proposition 13, passed in 1978. It limits the property tax rate to 1% of the assessed value, plus any voter-approved bonds. The assessed value is the purchase price at the time of acquisition, and it can increase by no more than 2% per year. This means long-time homeowners often pay significantly less than newer buyers.

When a property is sold, it is reassessed to its current market value. This is known as a "change in ownership." Exemptions exist for transfers between spouses, parent-child transfers (up to $1 million), and certain other family transfers. Property owners can also appeal their assessment if they believe it exceeds market value.

The tax is collected by the county tax collector. Payments are due in two installments: November 1 and February 1. Late payments incur a 10% penalty. For commercial properties, Proposition 13 applies similarly, but there are additional rules for reassessment upon transfer of ownership interests in entities that own real property.

Non-compliance with CA tax laws can result in significant penalties and interest. For income tax, failure to file a return by the due date results in a penalty of 5% of the unpaid tax per month, up to 25%. Failure to pay the tax due results in a penalty of 0.5% per month, up to 25%. Interest accrues at a rate set by the FTB, currently 5% per year.

For sales tax, failure to file returns or remit tax can lead to penalties of 10% of the unpaid tax, plus interest. The CDTFA can also revoke a seller's permit, effectively shutting down the business. In severe cases, criminal charges can be filed for tax evasion, which carries fines and potential imprisonment.

Property tax non-compliance results in a 10% penalty on late payments. If taxes remain unpaid for five years, the property can be sold at a tax auction. Additionally, the county can place a lien on the property, which prevents sale or refinancing until the taxes are paid.

If you are a resident or business operating in California, you should review your tax obligations with a qualified tax professional. They can help you determine your filing requirements, calculate your tax liability, and ensure compliance with all state and local tax laws. For specific advice on your situation, consult a certified public accountant (CPA) or tax attorney.
