Starting work this summer? Download the free HMRC app to get your NI number, check your tax code and stay on the right pay.

Young people finishing exams and entering the job market this summer are being urged by HMRC to download the HMRC app. The app is a free tool that can be used to provide quick access to essential employment and tax details. The app has already been downloaded by over 1.2 million people aged 25 and under. The app offers instant access to your National Insurance (NI) number, tax code, pay details and employment history.

This can be very useful information to have on-hand during the summer months when some 40,000 extra young workers are employed each month. Whether you're applying for work in hospitality, retail, leisure or seasonal roles like fruit picking, the app helps you stay job-ready with minimal hassle. Once employed, the app ensures you're on the correct tax code and receiving the right pay under the National Minimum Wage.

More than 146,000 people called HMRC last year after losing their NI number, but it is far quicker to retrieve it via the app where it can also be saved in your phone’s digital wallet. Nearly 90,000 users under 25 downloaded their NI number this way in the 12 months to April 2025.

The HMRC app is available to download, for free from the App Store for iOS and from the Google Play Store for Android. Once signed in, users can access it securely via face ID, fingerprint or a 6-digit PIN.

Young people are also reminded to check their payslips regularly to ensure they’re getting paid what they’re entitled to receive under National Minimum Wage requirements. Any underpayment concerns should be reported to HMRC or ACAS.
