Your Obligations
as an Employer
Register as Employer

Register with HMRC as an employer before your nanny starts. You must set up PAYE (Pay As You Earn) even if your nanny earns below the tax threshold — this is a legal requirement for all domestic employers.

Pay Tax & NI

Deduct Income Tax and National Insurance (employee Class 1) from your nanny's wages each pay period, then pay employer's National Insurance (15% above £5,000 secondary threshold in 2025/26) directly to HMRC.

Provide Pension

Auto-enrol your nanny into a workplace pension if they are aged 22–State Pension age and earn over £10,000 per year. Minimum employer contribution is 3% of qualifying earnings; employee contributes at least 5%.

Issue Payslips

Provide itemised payslips showing gross pay, each deduction, and net pay. Keep accurate employment records for at least 3 years — HMRC may request these during a compliance check.

Frequently Asked
Questions
Yes — you must register with HMRC as an employer even if your nanny earns below the tax threshold. This is a legal requirement for all domestic employers in the UK. You need to register before your nanny's first day of work.
Gross salary is the total before any deductions. Net salary (take-home pay) is what remains after deducting Income Tax, National Insurance, pension contributions, and any other deductions. Always clarify which figure you are discussing when negotiating salary — nannies often prefer to work to a net figure.
Yes, if your nanny is aged between 22 and State Pension age and earns more than £10,000 per year, you must automatically enrol them in a workplace pension scheme. You must contribute a minimum of 3% of their qualifying earnings, and they must contribute at least 5%.
While you can physically pay in cash, you are still legally required to register as an employer, deduct tax and NI, and report to HMRC. Paying "cash in hand" without making proper deductions is illegal and can result in significant penalties for both employer and employee. Bank transfers with proper payroll procedures are strongly recommended.
You must keep records for at least 3 years including: payslips, timesheets, tax and NI payments made to HMRC, pension contribution records, and any HMRC correspondence. A professional payroll service will typically maintain all these records on your behalf.
HMRC can impose penalties for late registration, incorrect tax payments, or failure to provide payslips. Penalties can range from £100 upwards to significant percentages of any unpaid tax. If you are unsure about your obligations, a professional payroll service provides peace of mind and ensures full compliance.
