💸 HMRC Interest Rates to Rise from April 2025 

From 6 April, HMRC increased the late payment interest rate by 1.5%, bringing it to Base Rate + 4.00%. This change applies across most taxes and is designed to encourage timely tax payments. 
 
Repayment interest (what HMRC pays you on overpayments) remains unchanged at Base Rate minus 1%, with a floor of 0.5%. 
 
📌 What this means: Late payments are now more costly—getting your returns and payments in on time is more important than ever. 
 

🔬 £13.9 Billion in UK R&D Investment 

The government is doubling down on innovation, with a record £13.9bn pledged to research and development. 
 
Highlights include: 
 
£8.8bn for UK Research and Innovation (UKRI) 
 
Funding for early dementia detection via advanced blood tests 
 
£86m for a wind turbine test site in Blyth, supporting clean energy growth 
 
💼 If your business invests in innovation, you may be eligible for R&D tax reliefs. We’ll help you navigate the claims process to ensure you don’t miss out. 

👶 Child Benefit: Higher Payments and PAYE Update 

 
From April 2025: 
 
Eldest/only child: £26.05 per week 
 
Additional children: £17.25 per week 
 
Reminder: Child Benefit ends on 31 August following a child’s 16th birthday, unless they stay in approved education or training. Parents must notify HMRC to continue receiving payments. 
 
New for Summer 2025: 
 
📎 Families affected by the High Income Child Benefit Charge (HICBC) can opt to have the charge collected via PAYE, removing the need for a self-assessment tax return. 

📈 Make the Most of Pension Tax Relief 

Pension contributions remain one of the most efficient ways to reduce your tax bill. 
 
Here’s what you could be claiming: 
 
20% relief for basic rate taxpayers 
 
40% for higher-rate taxpayers 
 
45% for additional-rate taxpayers 
And remember: 
 
Annual allowance: £60,000 
 
Carry forward: Use unused allowance from previous 3 years 
 
No lifetime cap: As of April 2023, there’s no longer a limit on total contributions 
 
Let’s review your pension strategy and make sure you're getting the full benefit. 

📲 MTD for Income Tax – Less Than 1 Year to Go
