You don't have to be running for office to get tripped up by the so-called Nanny Tax. If you've hired a nanny, housekeeper, gardener, babysitter, or anyone else who works in or around your home, that arrangement can come with real federal (and sometimes state) tax obligations — whether you knew it or not. Skip the paperwork, and the worker who was supposed to save you time and hassle can end up costing you far more than their hourly rate.

First: Is This Person Actually Your Employee?

The "Nanny Tax" isn't a special tax that only applies to nannies — it's just the common nickname for the employment taxes that kick in when you have a household employee. The whole analysis starts with one question: are you dealing with an employee, or an independent contractor?

You generally have a household employee when you control not just what work gets done, but how it gets done — regardless of whether the person works full time or part time, gets paid hourly or by the job, or came to you through an agency.

An independent contractor is different: they run their own operation, set their own methods, often bring their own tools, and typically work for multiple clients. The landscaping crew that shows up with its own equipment and its own schedule is almost always a contractor. The nanny who comes to your house five days a week, follows your instructions, and uses supplies you provide is almost certainly your employee.

This distinction isn't optional or a matter of convenience — you don't get to label someone a contractor just because payroll sounds like a hassle.

The Number That Matters for 2026: $3,000

If you pay a single household employee $3,000 or more in cash wages during 2026, you generally need to withhold and pay Social Security and Medicare tax on those wages — a combined 15.3% FICA rate, split 7.65% each between you and the worker (though many employers choose to cover the worker's share themselves). There are carve-outs for wages paid to a spouse, a child under 21, a parent, or an employee under 18 — but those exceptions come with their own fine print, so don't assume every family member or teenager automatically falls outside the rules.

Second: Budget for What This Actually Costs

Ideally, you're figuring this out before you make a hiring decision, not after your first pay period.

FICA (Social Security & Medicare): 6.2% Social Security and 1.45% Medicare, each paid by both you and the worker — 15.3% combined. If you decide to cover the employee's share yourself rather than withholding it from their paycheck, you're increasing your real cost of hiring them, and that payment carries its own reporting implications.

FUTA (Federal Unemployment Tax): This generally applies once you pay $1,000 or more in combined household-employee wages in any calendar quarter. It's calculated at 6% on the first $7,000 of wages per employee, though a credit of up to 5.4% for qualifying state unemployment contributions can bring the effective rate down substantially. Unlike FICA, this one's entirely on you — don't withhold it from the worker.

State unemployment tax: Rules and rates vary widely by state, so you'll need to check your own state's requirements.

Workers' compensation: Whether this is required — and at what threshold — also varies by state. Even where it isn't mandatory, it's worth a call to your homeowners insurance carrier to ask exactly what happens if your household employee gets hurt on the job at your house. You want that answer before an accident, not after.

Third: Collect the Right Paperwork Before Day One

Once you've confirmed you're hiring an employee, treat it like the professional relationship it is from the start.

• Form I-9 verifies work authorization. You review the documents and keep the completed form on file — you don't routinely send it anywhere.

• Get the employee's legal name, address, and Social Security number for payroll and year-end reporting.

• Form W-4 only comes into play if the employee wants federal income tax withheld — you're not required to withhold it otherwise, but you can if you both agree.

• You'll need an Employer Identification Number (EIN) — don't substitute your own Social Security number for this. If you've had an EIN from a past employee or a sole proprietorship, you may already have one.

• Check your state's requirements too — registration, withholding, unemployment, workers' comp, and new-hire reporting can all apply on top of the federal rules.

Get all of this squared away before the first day of work. Chasing it down a year later is a much bigger headache.

Fourth: Decide How You'll Actually Run Payroll

Use a payroll service. For anyone paying a household employee regularly, this is usually the easier route. Specialized household-payroll providers (and many accountants) can handle withholding calculations, direct deposits, state filings, and year-end reporting, so you're not trying to remember every deadline yourself.

Do it yourself. Completely doable if you're a DIYer — just understand that "I can handle this myself" doesn't mean the rules go away. You'll still need to track wages and taxes accurately, meet your state's requirements, issue the right forms, and keep solid records. Reliable payroll or accounting software makes this far more manageable.

Where Schedule H Fits In

Most household employers ultimately report their federal household employment taxes on Schedule H, filed with their personal Form 1040 — covering Social Security, Medicare, FUTA, and any federal income tax withheld. For 2026 wages, that's filed with your 2026 return in 2027.

Don't mistake Schedule H for permission to ignore the liability until tax season, though. It simplifies reporting — it doesn't make the tax bill disappear, and you may need extra withholding or estimated payments during the year to avoid an underpayment penalty.

The Forms You'll Likely Touch

• Form I-9 — work authorization

• Form W-4 — only if withholding federal income tax

• Form W-2 — required for 2026 if you paid at least $3,000 in Social Security/Medicare wages, or withheld any federal income tax

• Form W-3 — transmits W-2 data to the Social Security Administration

• Schedule H — reports household employment taxes with your 1040

• State forms — vary by location

For 2026 wages, W-2 and W-3 filings are generally due to the Social Security Administration — and to your employee — by February 1, 2027.

Is Paying Cash "Under the Table" Really a Shortcut?

It might feel simpler in the moment. It rarely stays that way. What happens when that employee later files for unemployment? Needs documented income for a loan? Decides to report the income themselves? Suddenly you're facing back taxes, penalties, interest, and possibly state employment issues — and that's before considering what happens if they're injured on your property and you discover too late that neither a workers' comp policy nor your homeowners insurance covers it.

Paying in cash isn't itself the violation. Failing to classify, report, and pay tax on those wages correctly is.

Can You Deduct Any of This?

Generally, no — paying someone to make your personal life easier doesn't turn those wages into a business deduction just because it frees up your time. There's one meaningful exception: if you're paying for childcare so you (and your spouse, if applicable) can work or look for work, some of those costs may qualify for the Child and Dependent Care Credit — a different benefit from the Child Tax Credit. Qualifying expenses are generally capped at $3,000 for one qualifying person or $6,000 for two or more, with the credit percentage tied to your income, claimed via Form 2441. That's a narrow, specific benefit — not a blanket deduction for your entire nanny's salary.

Keep the Paper Trail

At minimum, hold onto:

• The employee's name, address, and Social Security number

• Employment dates

• Wage amounts and payment dates

• Taxes withheld and taxes paid on the employee's behalf

• Copies of I-9, W-4, W-2, Schedule H, and any state filings

The IRS recommends keeping these records for at least four years past the due date of the return (or the date the tax was paid, whichever is later). If anyone ever questions how the worker was compensated, thorough records are the difference between a quick answer and a drawn-out problem.

The Bottom Line

If you're bringing on a nanny, housekeeper, gardener, or any other household help, treat it as the employment relationship it legally is. Confirm the classification, understand the true cost before you agree to a wage, gather the right paperwork up front, run payroll correctly, and make sure you're actually insured if something goes wrong. An informal arrangement can still create a very formal tax problem if it isn't handled properly from day one.
