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.

Employing family members can work well, but it does not mean you can skip the rules. HMRC expects full compliance on pay, tax, pensions, and working conditions—just as with any other employee.

When a new employee is added to the payroll it is the employers' responsibility to ensure they meet the employees’ rights and deduct the correct amount of tax from their salary. This includes any employees who are family members.

HMRC’s guidance is clear that if you hire family members you must:

• avoid special treatment in terms of pay, promotion and working conditions;
• make sure tax and National Insurance contributions are still paid;
• follow working time regulations for younger family members;
• have employer’s liability insurance that covers any young family members; and
• check if you need to provide them with a workplace pension scheme.

It is possible to employ young people if they are 13 or over but there are special rules about how long they can work and what jobs they can do. Young workers and apprentices have different minimum wage rates from adult workers for the National Minimum Wage.

There are different rules if you take on volunteers or voluntary staff, but the employer is responsible for health and safety and must give inductions and proper training for the 'job' at hand.

HMRC’s CEST tool gets a revamp from 30 April 2025, with clearer questions and updated guidance to help users decide employment status for tax—plus stronger backing from HMRC.

In a Written Ministerial Statement delivered on 28 April, the Exchequer Secretary to the Treasury announced a series of administrative and simplification measures designed to advance the government’s commitment to modernising the tax and customs systems.

Among these measures is an important update to HMRC’s Check Employment Status for Tax (CEST) digital tool, set to take effect from 30 April 2025. The CEST tool plays a key role in helping users determine whether a worker should be treated as employed or self-employed for tax purposes across both the private and public sectors.

The forthcoming changes aim to improve usability and clarity, making it more accessible and efficient for individuals and organisations alike. In conjunction with these technical improvements, HMRC will issue updated guidance to support users in navigating the revised set of questions, ensuring they are better equipped to use the tool correctly and confidently.

The service provides HMRC’s view as to whether IR35 legislation applies to a particular engagement and whether a worker should pay tax through PAYE as well as helping to determine if the off-payroll working in the public sector rules apply to a public sector engagement. HMRC has confirmed that it will stand by the outcome produced by the CEST tool, provided that the information entered is accurate and complete. However, HMRC will not stand by the results of contrived arrangements and designed to get a particular outcome from the service.

The service can be used by a variety of users, including:

• Workers providing services;
• Individuals or organisations engaging workers; and
• Employment agencies placing workers with clients.

If employees must work from home and their employer does not reimburse certain costs, they may be entitled to claim tax relief. Understanding the rules for household expenses, business travel, and equipment purchases is key to making a successful claim.

Eligibility to claim tax relief applies when homeworking is a requirement of the role. This may be the case if an employee's job necessitates living at a distance from the office, or if the employer does not maintain a physical office. Tax relief is generally not available where homeworking is a personal choice, even if permitted under the terms of the employment contract or where the office is occasionally at capacity.

Employees may claim a flat-rate tax relief of £6 per week (or £26 per month for monthly-paid staff) to cover additional household costs incurred as a result of working from home, without the need to retain detailed expense records. The value of the relief depends on the individual’s highest marginal rate of tax. For example, a basic-rate taxpayer (20%) would receive £1.20 per week in tax relief (20% of £6). Alternatively, individuals may opt to claim the actual additional costs incurred, provided they can supply evidence to HMRC in support of the claim. Backdated claims for up to four previous tax years are also permitted.

Tax relief may also be available for the use of a personal vehicle, a car, van, motorcycle, or bicycle, when used for business purposes. Relief is not available for ordinary commuting between home and a regular place of work. However, where travel is to a temporary workplace, or where the vehicle is used for other qualifying business journeys, tax relief may apply.

In addition, employees may claim tax relief on the cost of equipment purchased personally for work-related purposes, such as a laptop, office chair, or mobile phone, provided these are used exclusively or primarily for business use.

Redundant? You could receive up to £30,000 tax-free, whether it’s statutory pay or a better deal from your employer. Know your rights, check the 2025-26 limits, and understand how your age and service affect your payout.

There is a tax-free threshold of £30,000 for redundancy payments, regardless of whether the payment is your statutory redundancy pay, or a more generous amount offered by your employer.

If you have been employed for two years or longer and are made redundant, you are typically entitled to redundancy pay. The legal minimum you are entitled to receive is known as "statutory redundancy pay." However, there are exceptions to this entitlement, such as if your employer offers to retain you in your current role or provide suitable alternative employment, and you refuse the offer without a valid reason.

The amount of statutory redundancy pay is determined by your age and length of service, and is calculated as follows:

• Under 22: Half a week’s pay for each full year of service
• Aged 22 to 40: One week’s pay for each full year of service
• Over 41: One and a half weeks’ pay for each full year of service

If you were made redundant on or after 6 April 2025, your weekly pay is capped at £719. A maximum of 20 years of service taken into account. The maximum statutory redundancy payment for the tax year 2025-26 is £21,519.

Employers may opt to offer a higher redundancy payment, or you may be entitled to an increased amount based on the specific terms outlined in your employment contract.
