The Bank of England’s Monetary Policy Committee (MPC) last met on 18 December and, in a narrow 5–4 vote, decided to reduce the interest rate by 25 basis points, bringing it down to 3.75%. All four dissenting members voted to keep the rate at 4%. This marks the sixth interest rate reduction since August 2024.

Inflation continues to fall, with the latest figure at 3.2%. While this remains above the 2% target, inflation is now expected to return towards target more quickly in the near term. The Bank of England’s next meeting to consider interest rates is scheduled for 5 February 2026.

Following the interest rate cut, the late payment interest rate applied to the main taxes and duties on which HMRC charges interest will decrease from 8% to 7.75%. This change took effect on 29 December 2025 for quarterly instalment payments and will take effect on 9 January 2026 for non-quarterly instalment payments.

In addition, the repayment interest rate paid by HMRC on main taxes and duties will fall by 0.25 percentage points, from 3% to 2.75%, from 9 January 2026. The repayment rate is calculated as the Bank Rate minus 1%, subject to a minimum of 0.5%.

Students that work may need to pay Income Tax and National Insurance. Employers are required to calculate the amount of tax they need to pay on the basis that the students would be working for the rest of the tax year.

This means that an overpayment of income tax can often occur when a student or temporary worker earns more than their monthly tax-free allowance of £1,048 but over the course of the tax year earn less than their annual allowance. For example, a student only working over the summer and / or Christmas period and earning more than £1,048 a month may not have exceeded the current £12,570 tax free personal allowance. Students (and other temporary workers) are not required to pay any Income Tax if their earnings are below the tax-free personal allowance, currently £12,570.

A refund of overpaid tax can be requested online or using form P50 entitled Claim for repayment of tax. You can check your eligibility to make a claim for current or past tax years at https://www.gov.uk/claim-tax-refund/y

A refund claim for the current tax year can only be made if you meet the necessary conditions. Any students that are continuing to work for the rest of the tax year in part-time jobs should consider waiting until the end of the tax year in order to make a claim.

Writing-down allowances (WDAs) are a type of capital allowance that let you deduct a percentage of an asset’s value from your taxable profits each year. In some cases, you may be able to claim more relief using other capital allowances, such as the Annual Investment Allowance or first-year allowances.

There are two rates of WDA for plant and machinery. To calculate them, you first group your expenditure into separate pools:

• the main pool – this includes expenditure on most items – the rate is 18%; and
• the special rate pool includes special rate expenditure including long-life assets, integral features, certain thermal insulation and some cars – the rate is 6%.

Assets are grouped into pools, and WDAs are applied to the balance of each pool after adding new purchases, deducting disposal and accounting for any private use.

The Small Pools Allowance provides an alternative to WDAs. If the balance in the main or special rate pool is £1,000 or less, you can claim the entire amount in one year rather than applying the WDA percentage. The Small Pools Allowance cannot be used for single-asset pools and is prorated for accounting periods shorter or longer than 12 months. You can choose between claiming WDAs or the Small Pools Allowance, where possible, but cannot claim both.

As an employee, you pay tax on certain company benefits, such as cars, accommodation, and loans. Your employer calculates the tax you owe and deducts it through Pay As You Earn (PAYE). The amount of tax depends on the type and value of the benefit.

Some company benefits are tax-free, including childcare support and meals provided in canteens. Cash payments, however, are treated as earnings and are always subject to tax and National Insurance contributions.

Other taxable benefits you will pay tax on include the following:

Medical Insurance

You usually pay tax on the cost of the insurance premiums if your employer pays for your medical insurance. However, some health benefits are tax-free, including medical insurance while you are working abroad and annual check-ups.

Loans

You may have to pay tax on low-interest or interest-free loans from your employer if the loan is more than £10,000. The tax is calculated on the difference between the interest rate you pay and the official rate of interest set by the Bank of England. You could also be liable for tax if your employer lends money to one of your relatives.

Living Accommodation

If you (or one of your relatives) lives in accommodation provided by your employer, you may need to pay tax. The calculation depends on whether the accommodation costs are more than £75,000. You might not have to pay tax if the accommodation is provided so you can perform your job or do it more effectively, for example, agricultural workers living on farms.

As part of the Budget measures, the government confirmed plans to make some changes to the Construction Industry Scheme (CIS).

From 6 April 2026, HMRC will be able to take immediate action where a business makes or receives a payment that it knew, or should have known, was connected to fraud. In these circumstances, HMRC will have the power to remove Gross Payment Status (GPS) with immediate effect, assess the business for the associated tax loss, and impose a penalty of up to 30%. This penalty may be applied to the business itself or to its officers. Where GPS is withdrawn due to fraud or serious non-compliance, the business will also be barred from reapplying for GPS for a period of five years (an increase from the current one-year limit).

Alongside these measures, the government also plans to simplify the CIS by exempting payments to local authorities and certain public bodies. As part of this change the requirement for construction contractors to submit nil returns will be required. These changes are due to take effect from 6 April 2026 and will first be subject to technical consultation.

The CIS is a set of special tax and National Insurance rules for businesses operating in the construction industry. Under the scheme, businesses are classed as either contractors or subcontractors, and both must understand their tax obligations.

Qualifying contractors are required to deduct tax from payments made to subcontractors and pass these deductions to HMRC. The amounts deducted count as advance payments towards the subcontractor’s tax and National Insurance liabilities.

Subcontractors are not required to register for the CIS, but where they are not registered, contractors must deduct tax at a higher rate of 30%. Registered subcontractors are subject to a 20% deduction unless they qualify for GPS. Where GPS applies, no deductions are made by the contractor, and the subcontractor is responsible for paying all tax and National Insurance at the end of the tax year.

To qualify for GPS, a subcontractor must meet specific criteria, including a strong compliance history of paying tax and National Insurance on time, and carrying on a business that undertakes construction work or supplies construction labour in the UK.
