California Nanny Payroll Tax Calculator 2026 — Employer & Employee Withholding

Federal Taxes For California Nanny Employers (2026)

As a California household employer, you pay federal taxes on your nanny's wages. Three federal taxes apply: Social Security, Medicare, and FUTA. Social Security and Medicare are split between you and your nanny. FUTA is paid only by you — and California's credit-reduction status makes FUTA significantly more expensive than the standard rate suggests.

Social Security (6.2% Employer + 6.2% Employee)

Social Security tax is 12.4% total. The tax applies to the first $184,500 of wages in 2026. For a nanny earning $35,152/year, this equals $2,179.42 from you and $2,179.42 from your nanny.

Medicare (1.45% Employer + 1.45% Employee)

Medicare tax is 2.9% total with no wage cap — it applies to every dollar of wages. For a nanny earning $35,152/year, this equals $509.70 from each side. If a nanny's annual wages exceed $200,000, the employee owes an additional 0.9% Medicare tax on the excess (employee-only; you withhold it from their wages).

FUTA — California Employers Owe More Than the Standard Rate

FUTA is paid only by the employer. The gross rate is 6.0% on the first $7,000 of wages/year. Employers who pay state unemployment taxes on time normally receive a 5.4% credit, resulting in a net rate of 0.6% and a maximum of $42/employee. However, California is a FUTA credit-reduction state. Because California has an outstanding federal UI loan, the IRS reduces the credit California employers can claim. For 2025 wages, the effective CA FUTA rate was 1.8% — up to $126 per employee, not $42. For 2026 wages, the DOL determines the final credit reduction after November 10, 2026. California is expected to face at least a 1.5% reduction, potentially bringing the effective rate to approximately 2.1% ($147/employee). Budget for this and check the EDD FUTA page for the finalized rate.

Federal Income Tax Withholding (Optional — Only If You Both Agree)

You are not required to withhold federal income tax from wages you pay a household employee. Withhold it only if your nanny asks you to and you agree. Your nanny must give you a completed Form W-4 to set the withholding amount. Report any federal income tax you withhold with Schedule H when you file your own return. If you do not withhold, your nanny pays the income tax when filing their own return.

California State Taxes For Nanny Employers (2026)

California adds state-level taxes on top of federal. Two are employer-paid (SUI and ETT) and one is employee-withheld (SDI). A critical detail many employers miss: these taxes have two different quarterly wage thresholds.

California SUI / SUTA (3.4% Employer Only) — Triggers at $1,000/Quarter

SUI is paid only by the employer at a new-employer rate of 3.4% on the first $7,000/year (max $238/employee). Your rate may range from 1.5% to 6.2% based on experience rating. SUI is triggered when quarterly wages reach $1,000 or more — not at the lower $750 SDI threshold.

California ETT (0.1% Employer Only) — Triggers at $1,000/Quarter

ETT is 0.1% on the first $7,000/year (max $7/employee). Like SUI, ETT is triggered when quarterly wages reach $1,000 or more.

California SDI (1.3% Employee Withholding, No Cap) — Triggers at $750/Quarter

SDI is withheld from your nanny's paycheck at 1.3% of all wages — no cap. SDI withholding is required once you pay $750 or more in any calendar quarter — a lower bar than the $1,000 SUI/ETT threshold. For a nanny earning $35,152/year, SDI equals $456.98 annually. See how much disability or paid family leave pays with the California SDI & PFL calculator.

California Income Tax Withholding

You may withhold California state income tax if both parties agree. Your nanny completes DE 4 to set the withholding amount. The calculator estimates CA income tax using FTB 2025 tax-year brackets with a $5,706 standard deduction for single filers.

When Do You Owe California Nanny Taxes?

Four distinct thresholds govern when nanny taxes begin — two federal and two California state.

Federal FICA Threshold: $3,000 Per Year (2026)

Social Security and Medicare taxes apply once you pay a household employee $3,000 or more in cash wages during the 2026 calendar year. This threshold increased from $2,800 (2025) to $3,000 for 2026 per IRS Publication 926. FUTA is separate: triggered by $1,000 or more in any quarter of 2025 or 2026.

California Threshold 1 — SDI: $750 Per Quarter

Once you pay $750 or more in any single calendar quarter, you must register with the EDD within 15 days and begin withholding SDI (1.3%). A nanny earning $300/week for 3 weeks in a quarter ($900) crosses this threshold even if annual wages remain below $3,000.

California Threshold 2 — SUI and ETT: $1,000 Per Quarter

A separate, higher threshold of $1,000 per quarter triggers SUI (3.4%) and ETT (0.1%). Wages of $750–$999.99 in a quarter require SDI only — SUI and ETT do not apply until $1,000 is reached in a quarter.

The California "Stickiness" Rules — Two Independent Obligations

• SDI stickiness ($750/quarter): Once SDI withholding begins, you must continue withholding SDI through the rest of the current year and all of the following year, even if wages drop below $750 in later quarters.
• UI and ETT stickiness ($1,000/quarter): Once SUI and ETT obligations begin, you must continue paying them through the rest of the current year and all of the following year, even if wages drop below $1,000 in later quarters.
• Both rules can apply simultaneously, or only SDI stickiness may apply if wages stay between $750–$999.99 per quarter.

How To Register With The EDD As A California Household Employer

Registration is required within 15 days of paying $750 or more in wages in a calendar quarter (SDI threshold). The process takes about 20 minutes online.

Step 1: Gather Your Information

• Federal EIN — Apply free at irs.gov if you do not have one (5 minutes online).
• Business information — Your name, address, phone, and email. You register as a household employer.
• First payroll date — The date you first paid wages.
• Estimated annual wages — Your estimate for the current calendar year.

Step 2: Register Online Through EDD e-Services

1. Go to edd.ca.gov and select "Employer Registration."
2. Create an account and enter your EIN and business information.
3. Select "Household Employer" when asked about your business type.
4. Submit. You receive a California Employer Payroll Tax Account Number immediately or by mail within 10 business days.

Step 3: Collect DE 4 From Your Employee

Have your nanny complete DE 4 (California State Withholding Allowance Certificate) if you agree to withhold California income tax. Keep this in your records.

Step 4: Begin Filing Quarterly Returns

File quarterly DE 9 and DE 9C returns and deposit taxes via DE 88. You can file online through EDD e-Services.

California City-Specific Nanny Rules (2026)

California's state minimum wage is $16.90/hr effective January 1, 2026. San Francisco and Los Angeles update July 1; Oakland and San Diego update January 1. Pay the highest applicable rate based on where your nanny works. Convert an hourly wage to annual and monthly amounts with the California hourly paycheck calculator.

Overtime & Its Tax Impact For California Nannies

California's overtime rules depend on how your nanny's role is classified under the Domestic Worker Bill of Rights (DWBR). Using the wrong threshold can expose you to back-pay liability.

Classification: Personal Attendant vs. Other Domestic Workers

• Personal Attendant (most nannies): Spends at least 80% of working time on direct childcare. Overtime at 1.5× after 9 hr/day or 45 hr/week. No double-time applies.
• Other Domestic Workers: Non-caregiving duties exceed 20% of working time. Standard CA rules: 1.5× after 8 hr/day or 40 hr/week; double time (2×) after 12 hr/day.

Tax Impact of Overtime

Overtime wages are fully taxable. Both employer and employee owe FICA on overtime pay. Higher wages also increase SDI withholding (1.3%, no cap) and may push your nanny into a higher CA income tax bracket. For total employer-side payroll costs, try the California employer payroll tax calculator.

Additional Costs To Consider For California Nannies

Workers' Compensation Insurance

California law requires household employers to carry workers' compensation insurance. Non-compliance carries significant fines. Annual premiums typically range from $1,000 to $2,500.

Paid Sick Leave

Household employees accrue at least 1 hour of paid sick leave per 30 hours worked. California requires you to allow accrual of at least 40 hours (5 days) per year.

CalSavers Retirement Program

Mandatory for employers with 5 or more employees. Household employers with a single nanny are generally exempt. Verify at calsavers.com if combined household staff reaches 5 or more.

Health Insurance (Optional)

Not legally required for household employers, but increasingly expected by experienced nannies. Costs typically range from $5,000 to $15,000+ per year.

Live-In Nannies & Noncash Wages (Room and Board)

For a live-in nanny, the value of meals and lodging provided for the employer's convenience is generally excluded from taxable cash wages. Room and board provided this way is not subject to Social Security, Medicare, or FUTA tax — only cash wages count toward those taxes, so do not add the value of free rent or meals to your payroll tax calculations. A cash allowance paid instead of room and board is taxable cash wages. For overtime pay, California employers may count noncash meals toward wages using state meal credits: $6.10 per breakfast, $8.42 per lunch, and $11.28 per dinner (2026 CA DIR amounts).

DIY vs Payroll Service: Which Is Right For You?

Doing It Yourself (DIY)

• Cost: $0–$50/year
• Time: 5–10 hours/year for quarterly EDD filings, Schedule H, and W-2
• Risk: Higher — you must track the $750/qtr SDI threshold and the separate $1,000/qtr UI/ETT threshold, calculate accurately, and file on time.
• Best for: Organized employers comfortable with tax forms.

Using A Payroll Service

• Cost: $10–$30/month ($120–$360/year)
• Time: 5–10 minutes per pay period
• Risk: Lower — service calculates, files, and pays taxes; most include error guarantees
• Best for: Employers who want peace of mind or lack tax expertise.
