Child Benefit increases April 2025

Child Benefit has risen for 2025–26: £26.05 for eldest, £17.25 for others. Claim continues to age 20 in approved education. HICBC still applies for incomes over £60K – but PAYE option coming this summer!

The child benefit rates for the only or eldest child in a family increased to £26.05 (from £25.60) for the 2025-26 tax year and the weekly rate for all other children to £17.25 (from £16.95). Child Benefit is usually paid every 4 weeks and will automatically be paid into a bank account. There is no limit to how many children parents can claim for.

Taxpayers entitled to the child benefit should be aware that HMRC usually stop paying child benefit on the 31 August following a child’s 16th Birthday. Under qualifying circumstances, the child benefit payment can continue until a child reaches their 20th birthday if they stay in approved education or training. A qualifying young person is someone aged 16,17, 18 or 19 in full time non-advanced education or in approved training.

Any parents with children that remain in approved education or training should contact the child benefit office to ensure they continue receiving the child benefit payments to which they are entitled. No child benefit is payable after a young person reaches the age of 20 years.

Child benefit is usually payable for children who come to the UK. However, there are a number of rules which must be met in order to claim. HMRC must be notified without delay if a child receiving child benefit moves permanently abroad.

The High Income Child Benefit Charge (HICBC) currently applies to taxpayers whose income exceeds £60,000 in a tax year and who are in receipt of child benefit. The HICBC is charged at the rate of 1% of the full child benefit award for each £200 of income between £60,000 and £80,000. For taxpayers with income above £80,000 the amount of the charge will equal the amount of child benefit received.

The HICBC therefore either reduces or removes the financial benefit of receiving child benefit. It was announced as part of the Spring Statement measures that from this summer, families will have the option to report their Child Benefit payments and pay the HICBC directly through their PAYE tax code instead of filing a self-assessment tax return.

Don’t forget to update your NMW and NLW wage rates

Minimum wage rates rose on 1 April 2025. NLW now £12.21, and big increases for younger workers too. Make sure you're compliant – underpayment can cost up to £20K per worker and a director ban. Time to check your payroll!

Employers must ensure they are paying staff at least the National Minimum Wage (NMW) or National Living Wage (NLW). The NMW and the NLW are the minimum legal amounts that employers must pay their workers.

The new NMW and NLW rates came into effect on 1 April 2025. The NLW rate has now increased from £11.44 to £12.21. This represents an increase of 77p or 6.7%. The NLW is the minimum hourly rate that must be paid to those aged 21 or over. The increase represents a pay rise of over £1,400 a year for someone working full-time and earning the NLW.

The NMW (for 18-20 year olds) has increased from £8.60 to £10.00 an hour. This is largest increase ever in the NMW (a whopping 16.3% increase) that means younger workers having their pay boosted by up to £2,500 a year. This increase is part of a move to narrows the gap in wage rates for 18-20 years olds and the NLW and ultimately create a single adult wage rate for all those aged 18 and up. 

The NMW rates for 16 to 17 year olds increased from £6.40 to £7.55 – an increase of £1.15 or 18% per hour. The Apprentice Rate mirrors this increase.

It is important that employers ensure they have updated their wage rates and that they pay the legal minimum wage rates. There are significant penalties for employers who are found to have paid workers less that they are entitled to by law. If an employee has been underpaid, the employer must pay any arrears without delay. There are penalties for non-payment of up to 200% of the amount owed. The penalties are reduced by 50% if all of the unpaid wages and 50% of the penalty are paid in full within 14 days.

The maximum fine for non-payment can be up to £20,000 per employee and employers who fail to pay face up to a 15-year ban from being a company director as well as being publicly named and shamed.

Dealing with supply line interruptions

Supply line interruptions can be a nightmare for any business. Whether it’s a delay in deliveries, a shortage of materials, or problems with international shipping, things can grind to a halt fast. But with a bit of planning and a calm approach, you can keep things ticking over and reduce the impact.

1. Know your supply chain inside out

The first step is understanding exactly where your goods are coming from and how they get to you. Who are the suppliers? Are they reliant on overseas shipping? Do they have a history of delays? Map it all out so you can spot weak points before they become full-blown problems.

2. Build strong relationships with suppliers

Good relationships matter. If you’ve got a solid connection with your supplier, they’re far more likely to keep you in the loop if issues arise. It also makes it easier to negotiate alternatives or push your order to the top of the queue when things go wrong.

3. Keep a buffer stock if you can

Holding a bit of extra stock can be a lifesaver, especially for critical items. It might tie up a bit of cash, but it gives you breathing space if something doesn’t arrive on time. It’s all about balance – enough to cover a delay, but not so much that it eats into your profits.

4. Have a Plan B (and maybe a Plan C)

Diversify your supply sources where possible. If one supplier can’t deliver, having an alternative ready can mean the difference between a minor hiccup and a major crisis. Even just knowing who else you could call on helps you react quicker.

5. Stay informed and flexible

Keep an eye on news that might affect supply chains – like strikes, border issues, or economic changes. The sooner you know something’s up, the quicker you can respond. And stay flexible. Can you switch to a different product? Delay a launch? Being adaptable is key.

Final thoughts

Supply line interruptions aren’t always avoidable, but they don’t have to derail your business. With a bit of foresight and some strong backup plans, you can weather the storm and keep moving forward – even if the lorries aren’t.

Managing gross profit returns

Gross profit is one of the clearest indicators of how well your business is performing. It’s the amount left after deducting the cost of goods sold (COGS) from your sales revenue. Managing your gross profit returns well is crucial because it directly affects your bottom line and helps you understand whether you’re pricing correctly, controlling costs, and making enough to cover your overheads.

What Exactly Is Gross Profit?

Let’s start with the basics. Gross profit = Sales – Cost of Goods Sold. It doesn’t include things like rent, wages (unless they’re directly related to producing the goods), marketing, or admin costs. This figure tells you how much you’re making on the actual product or service before general running costs are factored in.

A healthy gross profit gives you the buffer to pay your bills, reinvest, or take a wage. Poor gross profit might mean your pricing is too low, your suppliers are charging too much, or your operations aren’t efficient.

Why It Matters

Many businesses keep an eye on sales and bank balances, but gross profit tells a deeper story. You might be selling a lot, but if your margins are tight, you could still be in financial trouble. Regularly checking your gross profit margin (usually shown as a percentage) gives you early warning signs if things start slipping.

Improving Gross Profit

There are several ways to manage and improve your gross profit returns:

  • Review Pricing: Are your prices competitive and profitable? Don’t undersell your value.
  • Reduce COGS: Negotiate with suppliers, buy in bulk where sensible, or streamline production.
  • Control Waste: In retail or food businesses, waste is a silent profit killer. Keep a close eye on stock control.
  • Focus on Bestsellers: Promote your highest-margin products or services more heavily.

Regular Monitoring Is Key

You should be reviewing gross profit monthly at least. Use accounting software or simple spreadsheets to track changes and spot trends. If you see margins slipping, act quickly. The sooner you fix it, the better your long-term prospects.
