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.

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.

A Company Voluntary Arrangement (also known as a CVA) is a special arrangement that allows a company with debt problems or that is insolvent to reach a voluntary agreement to pay its business creditors over a fixed period of time.

The arrangement is similar to the Individual Voluntary Arrangement (IVA) that can be used by a sole-trader or self-employed person who is unable to pay their debts.

An application for a CVA can only be made with the agreement of all directors of the company in question or all of the partners of a limited liability partnership (LLP). A CVA can only be created by using the services of an insolvency practitioner. They will be responsible for set up and administration of the arrangement.

Once an insolvency practitioner has been appointed the following steps will take place:

1. The insolvency practitioner will work out an ‘arrangement’ covering the amount of debt the company can pay and a payment schedule. They must do this within a month of being appointed.
2. The insolvency practitioner will write to creditors about the arrangement and invite them to vote on it.
3. A CVA must be approved by creditors representing at least 75% of the debt value of those who vote (rather than 75% of the total overall debt).

If the agreement is approved and the company does not meet the terms of the CVA then any of the creditors can apply to have the business wound up.

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.

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.

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.

A recent ruling has established that temporary worker arrangements do not constitute a single, continuous employment relationship in which workers retain the unfettered right to refuse assignments. This effectively confirms the prerequisite for a mutuality of obligation when accruing tax breaks.

Mainpay engaged temporary workers in the service sector, contending that its employment relationship constituted a single, albeit discontinuous form of employment, effectively rendering its various workplaces transient. Based on this viewpoint, Mainpay reimbursed its workers for travel and subsistence expenses and deducted these amounts from their income for tax purposes. Mainpay also used rounded sums, or benchmark scales, for subsistence expenses without obtaining formal dispensation from HMRC.

HMRC argued that each assignment was a separate instance of employment, making each workplace permanent for the purpose of a given assignment. This meant that travel and subsistence expenses were likely non-deductible without dispensation.

As the two contracts in question (2010 & 2013) were issued more than four years after the relevant tax year, this required HMRC to prove that the loss of tax was "brought about carelessly" by Mainpay so as to justify a six-year extended time limit. The Tribunal ruled in their favour, finding that neither the 2010 nor the 2013 contract constituted overarching contracts of employment, as the workers retained the unfettered right to refuse assignments. This, in turn, meant they lacked the necessary mutuality of obligation in the gaps between assignments. The Tribunal held that each assignment was an instance of separate employment and that the workplaces were therefore, in effect, permanent, making the expenses non-deductible. The Tribunal also found that Mainpay was "careless" in claiming the deductions, particularly in relation to the 2010 contract, because it had relied on vague assurances from employment lawyers.

This contention was escalated to the Court of Appeal, which rejected Mainpay’s argument that the parties’ intention should be decisive in construing the contract, as what essentially mattered was the reality of the arrangement, which was one of intermittent employment. Thus, each assignment was effectively under a separate contract of employment for the purposes of the Income Tax (Earnings and Pensions) Act 2003 (ITEPA) and, therefore, created a permanent workplace. The Court further upheld the finding that the loss of tax was "brought about carelessly" by Mainpay, validating the extended assessment time limit permitted under the Taxes Management Act 1970 (TMA).  

The case provides a clear distinction between a general agreement that governs future work and an actual contract of employment that lays out the terms under which future, separate contracts of employment will be formed. This type of agreement alone does not create a state of continuous employment. Companies are thus advised to seek advice when creating discontinuous employment frameworks in an effort to minimise tax liabilities.

Taking on the role of a company director is more than holding a title. Directors have legal duties that shape how a company is run, how decisions are made and how risks are managed. These responsibilities exist to protect the business, its shareholders, employees and anyone who deals with the company. Even in a small or family run company, these duties are taken seriously and can have personal consequences if ignored.

Directors must act in the best interests of the company. This means making decisions that support the long term success of the business, rather than personal gain. It also means considering the interests of employees, customers, suppliers and the wider community where relevant. Directors are expected to use reasonable care, skill and judgement. If a director has particular expertise, such as finance or technical knowledge, a higher standard may be applied in those areas.

Financial oversight is a key responsibility. Directors must ensure that accounts are kept up to date, tax filings are made correctly and that the company is solvent. If the company begins to face financial difficulty, directors must take action early. Continuing to trade while knowing the company cannot meet its debts can lead to personal liability.

Directors must also avoid conflicts of interest. If a personal interest overlaps with a business decision, it must be declared. Transparency and good record keeping are essential.

Good governance is not about bureaucracy. It is about understanding the business and managing it responsibly. Regular board discussions, clear financial reporting and practical risk management go a long way to protecting both the company and its directors.

Many businesses arrange insurance in the early days and then only look at it again when something changes, or when a renewal comes around. The difficulty with this approach is that risks evolve over time, and gaps in cover often only become visible when there is a claim. A short review with an insurance broker can help ensure that your policies reflect how the business currently operates and that protection remains adequate.

Business interruption

Business interruption cover is often misunderstood. It is designed to replace lost income while the business recovers from damage or disruption. The key issue is whether the indemnity period is long enough. If specialist equipment or premises are involved, recovery may take longer than expected. A broker can help evaluate assumptions and adjust cover accordingly.

Cyber risk

Cyber-attacks are now common across all sectors, not just large companies. Standard insurance policies rarely cover data breaches or ransomware incidents. Cyber insurance provides technical support as well as financial cover, which can make a major difference to recovery time.

Directors and officers

Directors and senior managers can face personal claims in relation to decisions they make. Reviewing Directors and Officers cover ensures that the right individuals are protected and that policy limits match the scale of business activity.

Supply chain and contractors

If contractors or suppliers are key to operations, it is worth checking who is responsible for what. Contracts should make insurance obligations clear, and your own policies should reflect any outsourced work.

Asset values and inflation

Rising costs mean many assets are now underinsured. Reassessing replacement values can prevent reduced payouts in the event of a claim.

A brief annual review can provide reassurance and avoid unwelcome surprises. If you would like support preparing for that conversation, we can help.

Recently, a clear legal precedent confirmed that the nature of an individual's work is determined by the reality of the actual employment relationship rather than by arbitrary titles. Mr. Gooch worked for the British Free Range Egg Producers Association (BFREPA) from 1 November 2011 until 26 April 2024, initially as a Policy Director on a "contracted services basis" for 2.5 days per week. The organisation, originally an unincorporated association, subsequently became an incorporated company in 2023 (BFREPA Ltd.), although the nature of its work was unaltered.

As Mr. Gooch's role evolved, so his compensation increased and, by 2016, he had effectively been promoted to Chief Executive of Services. Throughout his 12.5 years of engagement, he consistently submitted monthly invoices and was paid a retainer due to his self-employed status, without formally establishing a limited company. In February 2023, BFREPA's leadership expressed concern that their arrangement with Mr. Gooch looked remarkably similar to an employment relationship rather than a self-employed contract, even suggesting that the HMRC would likely classify him as an employee. As a consequence [of the evolving employment history of Mr. Gooch], in March 2023, BFREPA elected to give him 12 months' notice of termination, and he continued working until April 2024, at which point his email access was disabled, and he received a letter confirming that his contract would not be renewed. Mr. Gooch duly lodged claims against both defendants for unfair dismissal, unauthorised deductions from wages, unpaid holiday, wrongful dismissal for failure to pay statutory notice, and breach of contract relating to pension auto-enrolment. 

The Tribunal ruled that the claimant was a de facto employee, working under a contract of employment as defined by Section 230(1) of the Employment Rights Act 1996, Section 2 of the Working Time Regulations 1998, and Section 88(2) of the Pensions Act 2008. The Tribunal further concluded that personal service was a core requirement of the contract, one which contained no general substitution clause, and that the extent of the control was consistent with an employer-employee relationship for a senior employee alongside other strong indicators of a permanent employment relationship. The contracts also contained restrictive clauses that limited his ability to work for other companies in the same sector, a feature more commonly found in employment contracts than in contracts for service. 

This ruling provides a clear and detailed example of how a tribunal will look beyond the contractual terms to assess whether a person is an employee or a self-employed contractor. Employers cannot rely on a "contract for services" or a person's self-employed status to avoid the legal obligations of an employer. Instead, tribunals will scrutinise key factors such as the mutuality of the obligations, the degree of control, and the extent of integration in the business. Employers who treat long-term contractors like employees—providing them with a fixed monthly retainer, dictating their hours, and effectively integrating them into the business—risk having them reclassified as employees, and HR departments should ensure that contracts reflect the true nature of the relationship to avoid repercussions.  

If you are self-employed and your profits are above £12,570, you may need to pay Class 4 National Insurance, so it is important to understand how the rates and rules apply to you.

Self-employed individuals are usually required to pay Class 4 National Insurance contributions (NICs) if their annual profits exceed £12,570. These contributions are calculated based on profits and are used to fund various state benefits, including the state pension, unemployment benefits and the National Health Service (NHS).

For the current 2025-26 tax year, Class 4 NIC rates are set at 6% on profits between £12,570 and £50,270, with an additional 2% charged on profits above £50,270.

Certain groups are exempt from paying Class 4 NICs, including:

• Individuals under 16 at the start of the tax year.
• Individuals over State Pension age at the start of the tax year. If someone reaches State Pension age during the tax year, they remain liable for Class 4 NICs for the entire tax year.
• Trustees and guardians of incapacitated individuals are exempt from paying Class 4 NICs on that income.

The Class 4 NIC rate is lower than the corresponding rate for employees, who pay 8% on the same income levels. Both employees and the self-employed contribute 2% on income above the higher rate threshold.

The majority of individuals pay Class 4 National Insurance via self-assessment.
