At first glance, this looks like a simple math problem: private caregivers typically cost less per hour than going through an agency — nationally, about 20-30% less. But the hourly rate is only part of the real cost comparison — the rest shows up in taxes, risk, and what happens on the day your caregiver doesn't show up.
What an agency's higher rate actually covers
Agencies typically charge more per hour than a privately hired caregiver, and that markup is paying for real things, not just profit:
- Background checks and reference verification before someone is placed in your home
- Payroll administration, so you're not the one filing employment taxes
- Liability insurance and bonding, covering theft, property damage, or injury
- Backup coverage — a substitute caregiver if your regular one is sick or unavailable
- Ongoing supervision, and the ability to replace a caregiver who isn't working out, without you having to personally manage that conversation
What hiring privately actually requires — the part most families miss
Hiring a caregiver directly, outside an agency, usually means you've become what the IRS calls a "household employer" — the same category as hiring a nanny — and that comes with real obligations most families don't expect going in:
- The 2026 federal threshold is $3,000 per year. Pay one caregiver that much or more in cash wages during the year, and you owe Social Security and Medicare taxes (FICA) on their wages — often called the "nanny tax," and it applies to in-home senior caregivers the same way it applies to a nanny.
- FICA is 15.3% total, split evenly — 7.65% paid by you as the employer, 7.65% typically withheld from the caregiver's pay.
- A separate unemployment tax rule kicks in if you pay $1,000 or more in wages in any single calendar quarter — this triggers federal (and usually state) unemployment tax obligations, paid by you as the employer.
- You'll likely need to file Schedule H with your federal tax return, and issue your caregiver a W-2 — not the "just pay cash" arrangement many families assume is fine.
- Misclassifying a caregiver as an independent contractor (1099) when they're really your employee is a real risk — the IRS looks at whether you control what work is done and how it's done, not what you call the arrangement on paper.
The backup coverage question
This is the one families most often don't think about until it happens: what happens when your caregiver is sick, on vacation, or simply doesn't show up? With an agency, there's typically a system for covering that gap. With a private hire, there generally isn't, unless you've built your own backup plan — a second private caregiver on call, a family member who can step in, or an agency you'd call for short-notice coverage.
A framework for deciding, not just comparing hourly rates
The honest question isn't "which is cheaper" — it's which risks you're prepared to personally manage. Hiring privately can make real financial sense, especially for lower hours per week where the tax administration burden is manageable and you have a real backup plan. Going through an agency makes more sense when care needs are higher, when there's no realistic backup plan otherwise, or when being a household employer — payroll, tax filings, liability — feels like more than you want to take on personally.
