About Deductions

This estimate includes standard federal withholding, FICA taxes (7.65%), and state income tax rates applicable in CALIFORNIA. Local county taxes are factored in where applicable.

Understanding Your Paycheck in CALIFORNIA

When you receive a paycheck in Yolo County, a portion of your gross earnings is set aside for mandatory and optional deductions. The three core mandatory withholdings are:

• Federal Income Tax: Collected by the Internal Revenue Service (IRS) based on the tax brackets that apply to your filing status and the allowances you claim on Form W‑4.
• California State Income Tax: Administered by the Franchise Tax Board (FTB) and taken according to California’s progressive tax schedule.
• FICA (Social Security and Medicare): A combined 7.65% payroll tax (6.2% for Social Security up to the annual wage base and 1.45% for Medicare with no wage cap). Your employer matches these amounts, bringing the total FICA contribution to 15.3% of earnings.

In addition to these, California employees also see deductions for State Disability Insurance (SDI) – currently 1.1% of wages up to $153,164 – which funds temporary disability and Paid Family Leave benefits. None of these withholdings are optional, but you can influence the amount taken for federal and state income tax by adjusting your W‑4 elections.

Federal Tax Withholding

The IRS uses the information you provide on Form W‑4 to estimate how much federal income tax to withhold each pay period. Your choices affect the following:

• Filing Status: Single, Married filing jointly, Married filing separately, or Head of Household. Each status has its own tax brackets and standard deduction amount.
• Number of Dependents/Allowances: More allowances reduce the amount withheld, while fewer allowances increase it.
• Additional Withholding: You can specify an extra dollar amount to be taken out each paycheck if you anticipate owing tax at year‑end.

The federal tax system is progressive: income is taxed at increasing rates as it moves through the brackets (10%, 12%, 22%, 24%, 32%, 35%, and 37% for 2024). Your employer calculates withholding by applying the appropriate bracket to the portion of your wages that remains after accounting for the allowances you claimed. If you under‑withhold, you could face a tax bill and possible penalties; over‑withholding simply means you’ll receive a larger refund, but it also means less cash flow throughout the year.

State & Local Taxes

California’s income tax is also progressive, with ten brackets ranging from 1% to 12.3% for 2024. The state adds a 1% Mental Health Services Tax on taxable income over $1 million. Unlike some states, California does not have a county‑level income tax, so Yolo County residents are not subject to additional local income levies.

In addition to the regular state income tax, the following payroll‑related taxes apply in California:

• State Disability Insurance (SDI): 1.1% of wages up to the annual limit, retained on your paycheck.
• California Personal Income Tax (PIT) Withholding: Calculated using the employee’s state W‑4 (DE 4) and the state’s tax tables.

These are automatically deducted by your employer; you do not need to remit them separately.

Maximising Your Take‑Home Pay

While mandatory taxes cannot be avoided, several strategies can help you keep more of each paycheck:

• Adjust Your W‑4 Wisely: Review your allowances and additional withholding each time you experience a major life change (marriage, new child, side‑gig income). Use the IRS Tax Withholding Estimator to avoid surprises.
• Contribute to a 401(k) or 403(b): Pre‑tax contributions lower both federal and state taxable wages. For 2024, you can defer up to $23,000 ($30,500 if age 50 or older).
• Health Savings Account (HSA): If you have a high‑deductible health plan, HSA contributions are pre‑tax at the federal level and also reduce California taxable income.
• Flexible Spending Accounts (FSAs): Contributions for medical or dependent care are excluded from taxable wages, cutting both federal and state tax liability.
• Take Advantage of Tax Credits: The California Earned Income Tax Credit (CalEITC) and federal Child Tax Credit can directly reduce what you owe, effectively increasing net pay.
• Review Benefits Elections Annually: Opting for employer‑paid benefits (e.g., dental, vision) can lower your taxable wage base.

By regularly revisiting your payroll elections and leveraging pre‑tax savings vehicles, you can optimize your take‑home pay while staying compliant with federal and California tax requirements.
