Nanny Cash Risks: How to Pay Nanny Taxes Legally

It sounds so simple. You agree on a net hourly rate with your new caregiver, and you send an e-transfer or hand over an envelope of cash every Friday. No paperwork, no logging into government portals, no headache. Many parents looking to simplify their childcare search ask themselves: Can you pay a nanny cash? It feels like a frictionless, win-win setup for a busy household.

But while paying nanny cash seems incredibly convenient upfront, it is a legal and financial ticking time bomb for Canadian families.

When I hired my first nanny, I was in the exact same boat. I had no idea that bringing a caregiver into my home would suddenly require me to register with the Canada Revenue Agency (CRA) for a business number, calculate and remit source deductions, and meticulously track provincial employment standards. Instead, I found myself spending countless late nights staring at a complex spreadsheet, trying to manually calculate fluctuating hours and pay.

In the back of my mind, I knew it was not as simple as just handing over cash. But I completely underestimated just how much I would have to learn and do to stay compliant. That frustrating spreadsheet nightmare is the exact reason I built RoostPay.

If you are currently wrestling with the temptation of under-the-table payments, let’s dive into why “nanny cash” is a massive risk, what a compliant nanny tax framework actually looks like, and how to pay nanny taxes legally without sacrificing your sanity.

Can you pay a nanny cash in Canada?

The short answer is yes—you can physically pay your employee using cash or a direct bank transfer. However, you cannot do it “under the table.” Every single dollar paid to your caregiver must be reported to the CRA.

A common misconception among parents is that a nanny can be treated like a casual neighborhood babysitter or an independent contractor who handles their own taxes. The CRA draws a very sharp legal line here: because you control your nanny’s schedule, provide the workplace (your home), and dictate how the work is completed, your nanny is legally classified as an employee.

Because they are an employee, you are legally responsible for deducting income tax, Canada Pension Plan (CPP), and Employment Insurance (EI) at the source—even if you pay them in physical cash. For a full breakdown of what domestic employers owe, see our Canadian nanny tax guide for 2026.

The hidden dangers of paying under the table

Skipping the paperwork might save you twenty minutes this weekend, but it exposes your household to three massive liabilities:

1. The CRA audit roulette

If your nanny eventually leaves your employment and files for Employment Insurance (EI), or if they apply for a car loan or a mortgage and list your household as their employer, the CRA will look for a paper trail. If they find an unregistered employer paying undocumented cash, they will launch an investigation. You can be held liable for years of back-dated employer contributions, compounding interest, and severe non-compliance penalties.

2. Massive personal liability

If an undocumented caregiver is injured on your property, your standard homeowner’s insurance policy will likely deny the liability claim because you are employing an undeclared worker. Without provincial workers’ compensation coverage (like WorkSafeBC or WSIB), you could be personally sued for workplace injuries and medical expenses.

3. Losing out on tax write-offs

When you pay a nanny legally, you receive a legitimate paper trail that allows you to claim their wages as a childcare expense deduction. This can drastically lower your household’s taxable income, putting thousands of dollars back in your pocket. When you pay under the table, you forfeit these massive savings entirely.

How it hurts your caregiver

Paying under the table does not just put your family at risk; it actively hurts the person looking after your children. Cash-paid nannies have a completely blank employment history. This means:

• They cannot establish verifiable income to rent an apartment or secure a line of credit.
• They have zero access to parental or maternity leave benefits.
• They are completely cut off from regular EI protection if your family’s childcare needs change and you have to let them go.
• They are not contributing to their future CPP retirement fund.

Paying your nanny legally is not just about government compliance; it is an act of professional respect that protects their financial future.

How do I pay nanny taxes legally?

If you want to transition away from cash and establish a legal framework, here is the compliance blueprint you must follow:

• Register a payroll account: You must apply to the CRA for a dedicated Business Number with a payroll program account. Our guide on getting a CRA business number for nanny and caregiver payroll walks through the registration steps.
• Calculate gross-to-net pay: Every pay period, you must calculate their gross earnings, factor in any non-cash taxable benefits (like room and board), and deduct the correct ratios for federal tax, provincial tax, CPP, and EI.
• Match employer contributions: As an employer, you must match their CPP contributions dollar-for-dollar and pay 1.4 times their EI premium.
• Remit to the CRA: You must send these withheld taxes and employer matches to the Receiver General by the 15th of every subsequent month. See payroll remittance basics for domestic employers for timing and what gets bundled into each payment.
• Issue year-end slips: Every February, you are legally required to file a T4 summary and issue a T4 slip to your employee.

Even when you pay legally, the method you use to move money still matters. Compare cash, e-Transfer, and direct deposit for domestic employees to understand which options create the cleanest audit trail.
