Employees with company cars may be paying unnecessary tax on private fuel, when reimbursing the cost of private fuel in full can often remove the car fuel benefit charge altogether.

Where an employee is provided with a company car and fuel for private use, the default position is that the employee must pay the car fuel benefit charge. The amount of the charge is calculated based on the car’s CO2 emissions and applied to the car fuel benefit multiplier, which is currently £28,200 and is set to increase to £29,200 for the 2026–27 tax year.

Avoiding the car fuel benefit charge is possible if the employee reimburses their employer for all fuel used for private journeys, a process known as ‘making good’. Private fuel includes all fuel used for commuting to and from work. To do this, employees should keep a record of private mileage and repay their employer using the published advisory fuel rates. These rates are designed to reflect average fuel costs and are updated quarterly.

If properly documented, HMRC will accept that no car fuel benefit charge is due, meaning the employee avoids the income tax liability on the private fuel. In most cases, reimbursing the employer is far cheaper than paying the tax, especially for employees with relatively low private mileage.

The car fuel benefit charge will still apply if it cannot be demonstrated to HMRC that the employee has reimbursed the full cost of fuel used for private journeys, including commuting. To prevent this, employees must maintain a detailed log of private mileage and ensure they make good the cost of all fuel provided for private use.

With the 31 January deadline approaching, thousands of taxpayers are using HMRC’s Time to Pay service to spread the cost of their self-assessment tax bill rather than facing immediate payment pressure.

HMRC has reported that thousands of people have set up payment plans to help spread the cost of their self-assessment tax bill. Taxpayers with outstanding tax liabilities, may be eligible to receive support with their tax affairs through HMRC’s ‘Time to Pay’ service. Almost 18,000 self-assessment payment plans were set up between 06 April 2025 and 30 November 2025. The deadline to file and pay any tax owed for the 2024-25 tax year is 31 January 2026.

If you owe tax to HMRC, you may be able to set up an online ‘Time to Pay’ payment plan depending on the type of tax debt and your circumstances. For self-assessment, you can create a payment plan online if you’ve filed your latest tax return, owe £30,000 or less, are within 60 days of the deadline and have no other debts or payment plans with HMRC.

A Time to Pay arrangement cannot be set up until a self-assessment return has been filed. If the tax owed is more than £30,000, or a longer repayment period is needed, people can still apply but will need to contact HMRC directly. HMRC will typically ask for details about your income, expenses, other tax liabilities, and any savings or assets, which they may expect you to use toward your debt.

HMRC will usually only offer taxpayers the option of extra time to pay if they think they genuinely cannot pay in full now but will be able to pay in the future. If HMRC do not think that more time will help, then they can require immediate payment of a tax bill and start enforcement action if payment is not forthcoming.

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%.

Are you ready for Making Tax Digital for Income Tax (MTD for IT)? This new way of reporting will become mandatory in phases from April 2026. If you are self-employed or a landlord earning over £50,000, now is the time to prepare for digital record keeping, quarterly updates and the new penalty system that will apply under MTD for IT.

The date from which you must start using MTD for IT depends on your level of qualifying income. If your qualifying income exceeded £50,000 in the 2024–25 tax year, you will need to use MTD for IT from 6 April 2026. If your qualifying income exceeded £30,000 in the 2025–26 tax year, you will need to use MTD for IT from 6 April 2027. Where qualifying income exceeds £20,000 in the 2026–27 tax year, the government has confirmed that MTD for IT will apply from April 2028. Qualifying income is defined as the total income you receive in a tax year from self-employment and property before expenses.

You are currently exempt from MTD for IT if you meet specific conditions that automatically exempt you from the service, such as reasons relating to age, disability, or location, if you have applied for and been granted an exemption by HMRC, or if your qualifying income is £20,000 or less in a tax year.

HMRC’s guidance on MTD for IT has been updated and now includes further information on both permanent and temporary exemptions. It explains which exemptions apply automatically and which require an application. Permanent exemptions are generally automatic and continue to apply unless your circumstances change. You will need to apply for an exemption if you believe you are digitally excluded from using MTD for IT. If you are not required to use MTD for IT, you must continue to report your income and gains through the self-assessment tax return where applicable.

As we move into the start of 2026, it is not that long until the current 2025–26 tax year comes to an end and there are a number of payroll annual reporting obligations that must be completed. This includes sending a final PAYE submission for the tax year. The final Full Payment Submission (FPS) needs to be submitted on or before your employees’ final payday for the 2025–26 tax year.

It is also important that employers remember to provide employees with a copy of their P60 form by 31 May 2026. A P60 must be given to all employees that are on the payroll on the last day of the tax year, 5 April 2026.

The P60 is a statement issued to employees after the end of each tax year that shows the amount of tax they have paid on their salary. Employers can provide the P60 form on paper or electronically. Employees should ensure they keep their P60s in a safe place as it is an important record of the amount of tax paid.

In addition, a P60 is required in order that an employee can prove how much tax they have paid on their salary, e.g.:

• to claim back overpaid tax;
• to apply for tax credits;
• as proof of income if applying for a loan or a mortgage.

Employees who have left their employment during the tax year do not receive a P60 from their employer, as the same information will be on their P45.

The deadline for reporting any Class 1A National Insurance contributions and submitting P11D and P11D(b) forms to HMRC for the tax year ending 5 April 2026 is 6 July 2026.
