Most employees will come across forms such as the P45, P11D and P60 during their working life, and knowing what each one is for can make it much easier to keep track of your tax position.

A P45 is issued to employees who leave their employment or lose their job. The P45 shows how much tax you have paid during the current tax year (6 April to 5 April). The form has four parts: your employer sends Part 1 to HMRC, gives you Part 1A for your records, and you pass Parts 2 and 3 to your new employer or Jobcentre Plus. Employers are legally required to issue a P45. If you do not have one, for example when starting your first job then your new employer will ask for details via a starter checklist to determine your correct tax code.

A P11D form is used by employers to list certain ‘benefits in kind’ provided to directors or employees. P11D forms are used to provide information to HMRC on all Benefits in Kind (BiKs), including those under the Optional Remuneration Arrangements (OpRAs) unless the employer has registered to payroll benefits. Payrolling benefits removes the requirement to complete a P11D for the selected benefits. The completed P11D form is submitted annually to HMRC. The deadline for submitting the 2025-26 form is 6 July 2026. The form can be submitted using commercial software or via HMRC’s PAYE online service.

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. The deadline for employers to provide employees with a copy of their P60 form for the 2025-26 tax year is 31 May 2026. A P60 must be given to all employees that were on the payroll on the last day of the 2025-26 tax year.

It is quite common for tax codes to be wrong, particularly if your income or employment situation has changed, so it is worth taking a few moments to check that HMRC has the correct information about you.

HMRC usually updates your tax code automatically when your income changes, using information provided by your employer. However, if HMRC has inaccurate details about your income you may be given an incorrect tax code. To fix this, ensure HMRC has your up-to-date income details and check what you need to do if you are on an emergency tax code.

If you believe your tax code is wrong, you can use HMRC’s Check your Income Tax online service to update employment details or to report income changes that might affect your tax code. For example, you can add company benefits, missing income sources, claim employment expenses and update your estimated taxable income. HMRC may then adjust your tax code based on these updates.

If you cannot access the online service, you can contact HMRC directly. Once your details are updated, HMRC will inform both you and your employer or pension provider if your tax code changes. Your next payslip should show your new code and any corrections to your pay.

At the end of the tax year, if you have paid too much or too little tax, HMRC will issue either a P800 tax calculation letter or a Simple Assessment letter to explain any refund or amount owed.

Where cryptoasset tokens (also known as cryptocurrency) are held personally, this investment is usually undertaken in the hope of making a capital appreciation in its value or to make particular purchases. 

HMRC is clear that these holdings will usually be subject to Capital Gains Tax (CGT) if there is a gain when disposing of these assets by: 

• selling tokens
• exchanging tokens for a different type of cryptoasset
• using tokens to pay for goods or services
• giving away tokens to another person (unless it is a gift to your spouse, civil partner or charity)

If you have unpaid tax on cryptoasset gains, there is a specific voluntary disclosure service that can be used. This service can be used for exchange tokens (such as bitcoin), NFTs (non-fungible tokens) and utility tokens.

Before making a voluntary disclosure, you will need to: 

• collect information about the cryptoassets you owe tax on; 
• work out how many years you need to declare unpaid tax for; 
• work out the CGT and Income Tax you owe; and 
• work out any interest you owe. 
• work out any penalties you will be liable for 

The number of years you must disclose unpaid tax depends on why it was not paid correctly. If you took reasonable care but still underpaid, you must disclose and pay for the last four years. If you did not take care, you must disclose for six years. However, if you deliberately failed to pay or knowingly gave incorrect information, you must disclose and pay for up to 20 years of unpaid tax.

Your disclosure must include all unpaid tax, interest and penalties. You can use HMRC’s calculators to work out the correct interest and penalty amounts. Once you submit your disclosure, HMRC will usually issue a payment reference number within 15 working days, and you must pay the full amount within 30 days of submitting a disclosure.

After reviewing your disclosure, HMRC will either send you a letter confirming acceptance of your offer or contact you if it cannot be accepted. If HMRC finds that you knowingly provided false or incorrect information, they may reopen your tax affairs and can impose higher penalties.

If your business imports goods into the UK, it is important to be familiar with the Customs Declaration Service and to ensure that any duty payments are made correctly and on time to avoid delays, interest or penalties.

The Customs Declaration Service (CDS) is a specially designed IT platform used for completing customs declarations for businesses that import or export goods from the UK. All electronic import declarations must be submitted through the CDS.

When you import goods into the UK using the CDS, you must pay any tax due promptly. Payments should reach HMRC by the deadline, and if that falls on a weekend or bank holiday then the payment must arrive by the previous working day.

Late payments may result in interest charges and / or penalties. You will need your unique 16-character reference number starting with “CDSI,” which is specific to each declaration, to make a payment. Using the wrong number can delay the release of your goods.

Payment can be made online through your bank account or with a debit or corporate credit card (personal credit cards are not accepted). Online bank payments are usually instant but may take up to two hours to appear, while card payments are recorded on the date made.

Payments can also be made by bank transfer. CHAPS or Faster Payments usually arrive the same or next day, while BACS take about three working days. UK payments should go to HMRC’s Customs Duty Schemes account (sort code 08 32 10, account number 14077970). Overseas payments must be made in GBP. There are also options to pay by cheque, allowing three working days for delivery. If there are payment issues or further advice is required, you can contact HMRC’s National Clearance Hub.

There is a trivial benefit-in-kind (BiK) exemption that applies to small, non-cash gifts (such as a bottle of wine or a bouquet of flowers) that are occasionally given to employees.

This exemption enables employers to offer modest, tax-efficient rewards while simplifying the administration of BiKs. The BiK exemption allows businesses to recognise employees in a small way without creating additional reporting obligations or tax liabilities.

Trivial benefits are a simple and effective way to provide gestures of goodwill or recognition, as long as they are not given as a reward for work performed or duties carried out. Typical qualifying occasions include events such as a marriage, the birth of a child or other personal landmarks.

Employers also benefit since these trivial BiKs do not need to be included in PAYE settlement agreements or reported on P11D forms, and they are exempt from Class 1A National Insurance contributions.

The tax exemption applies to trivial BiKs where the benefit:

• costs £50 or less;
• is not cash or a cash voucher;
• is not a reward for work or performance; and
• is not in the terms of an employee’s contract.

Trivial benefits provided through a salary sacrifice arrangement are not exempt from tax. In such cases, the employer must report them on form P11D, using the higher of the amount of salary the employee gave up, or the cost of the trivial benefit provided.

For directors or officeholders of close companies (and their families), there is an annual cap of £300 on trivial benefit gifts. The £50 limit still applies per gift but allows up to £300 of non-cash benefits per person each year. If any single gift exceeds £50, the full value becomes taxable.
