California Income Tax
California does not use the federal standard deductions. Instead, it uses its own standard deduction of $4,803 for a single.
The income is taxed in the following brackets
|lower bracket||upper bracket||tax rate||amount on 100K|
As a resident of California, you have to pay $5,841 in state taxes per year. This is calculated for filing “single” and with tax rates for 2021.
State Disability Insurance (SDI)
The California government taxes every wage earner for short-term disability insurance.
This insurance pays benefits in case you are unable to work for non-work-related reasons. For example, it pays when you have to stay home because of a sick child or an infection with COVID-19.
The benefits level is about 55% of your gross wages or salary.
In 2021 the Tax rate for the SDI is 1.2% of your income. This applies to the first $128,298 of your income.
On a 100K salary, you’ll pay $1,198.08 short-term disability insurance a year.
CA Taxation Summary
With an income of $99,840 a year, you pay $14,970 in federal income tax and $7,637.76 in federally mandated insurance (FICA tax).
Furthermore, you pay $5,841 CA state tax and $1,198.08 state-mandated insurance (SDI). Your salary will shrink to $70,193.22 a year after taxes. This assumes you are filing taxes as “single”.
Tax Rates on Extra Income (Marginal Tax Rate)
We all strive for extra income, such as overtime pay or a performance bonus. Most income tax rates rise with the income you want to know which rate you are going to pay on additional income.
Marginal State Income Tax Rate
Your marginal rate for the California state tax is 10.50%. This means for an extra dollar of earned income you’ll pay 10.50% cents to the Franchise Tax Board of California.
California’s state income rate rises with increasing income, which means it is progressive. Thus, you want to know which taxes are due for extra income. The marginal tax rate gives you this information.
Combined Marginal Income Tax Rate (Fed + CA)
The federal tax rates also rise with increasing income. Your federal marginal rate is 31.65%. This includes the FICA taxes Social Security and Medicare. Your state marginal rate is 10.50%, including the SDI contribution.
Your combined marginal rate is 31.65% + 10.50% = 42.15%.
Example for Marginal Tax Rate
For example, an annual bonus of $2,080 (equals $1 / hour) will increase your tax bill in California by $218. Your Federal marginal rate is 31.65% and you owe the Internal Revenue Serice (IRS) $658.32 on that bonus.
Of that $2,080 (equals $1 / hour) bonus, you will see only $1,203 in your paycheck. The government taxes you on that last $2,080 (equals $1 / hour) at a combined rate of 42.15%.
Your Average Tax Rate
While the marginal tax rates look scary, your average tax rates are less so.
On an income of $99,840, you pay a combined average tax rate of $29.69%.
We base the average tax rate on the gross income without standard deductions.
California Tax Structure
California’s income tax rates are progressive. This means the share you pay in taxes increases with your gross income.
California has its own standard deductions, separate from federal standard deductions. The standard deduction ensures that a very minimal income is not taxed at all. The standard deduction in California is $4,803.
California state income tax depends on your filing status. If you are filing “single”, you will have a more progressive tax schedule. If you file “married filing jointly”, your tax brackets double and you share this income with your spouse. You can also file “married separate” and be treated as “single”. Furthermore, as a qualified widower, you can pay taxes like you were still married filing jointly.
Other Taxes in California
