Transactions

At what stage of a transaction should a tax adviser be consulted?


Ideally, tax advice should be taken as early as possible, often well before Heads of Terms are agreed. Early involvement allows us to contribute to the transaction structure, identify potential risks and implement pre-sale planning that can significantly improve post-tax outcomes. Nevertheless, we regularly support clients at any stage of the process, including during live negotiations.

How do you support buyers and sellers differently during a transaction?



Our approach is tailored to your position in the deal. For buyers, we focus on tax due diligence, deal structuring, risk identification and negotiating appropriate tax protections. For sellers, we concentrate on optimising the tax outcome, advising on deal structures, supporting negotiations and ensuring the transaction is correctly reported to HMRC, both at completion and afterwards. We bring these strategies to each engagement.

Can you help reduce the tax payable on the sale of a business?


Yes. A core part of our role is to structure transactions in a commercially robust and tax-efficient way. This may involve pre-sale restructuring, the use of reliefs, deferred consideration planning, management incentives, or alternative exit routes such as Employee Ownership Trusts. Our objective is always to maximise post-tax value while ensuring full compliance.

Do you have experience with complex or cross-border transactions?

We regularly advise on complex transactions, including those involving overseas buyers, sellers, or group structures. Through our international tax network, we coordinate local jurisdiction advice and present a clear, consolidated view of the tax risks and opportunities, enabling informed decision-making on the optimal transaction structure.

Is K3 Tax Advisory industry-specific?

No. We work across a wide range of sectors, with particular strength in advising owner-managed and entrepreneurial businesses. Our focus is on the tax and transaction mechanics rather than the industry itself, allowing us to bring broad experiences and proven strategies.

Corporate & Structuring

When should corporate structuring advice be sought?

The best time to seek structuring advice is well before a major event such as a sale, succession, investment or family reorganisation. Early planning creates flexibility, reduces risk and allows tax-efficient solutions to be implemented without time pressure. However, we are equally experienced in stepping in when restructuring is required urgently.

Can corporate restructuring really be achieved without triggering significant tax costs?

Yes, in many cases. With specialist knowledge and careful planning, transactions such as demergers, group reorganisations, and asset separations can often be completed on a tax-neutral basis. Many clients are surprised by what can be achieved once the full range of available reliefs and structuring options is explored.

How do you support family businesses and succession planning?

We help families navigate the financial and emotional complexities of passing wealth and control between generations. Our advice focuses on creating fair, practical structures that preserve family relationships, protect asset value and manage tax exposure. Every solution is tailored to the family’s long-term objectives rather than a one size fits all approach.

Do you work alongside existing accountants and legal advisers?

Absolutely. We regularly collaborate with clients’ existing advisers, as well as with our own specialist legal and corporate finance partners where required. Our role is to provide deep tax structuring expertise while ensuring the overall process is joined-up, compliant, and focused on achieving the best possible outcome.

What makes K3 Tax Advisory different from a regular accountancy firm?

Corporate structuring is a highly specialised area, and errors can be extremely costly. Unlike most general accountancy practices, we advise on complex restructurings and demergers on a daily basis. This depth of experience allows us to identify creative, compliant solutions that many business owners, and even advisers, may not realise are available.

Employer Solutions

When should a business seek Employer Solutions tax advice?

Employer tax advice is most valuable before issues arise, particularly when engaging contractors, implementing share schemes, expanding internationally, or changing pay and benefit structures. However, many clients approach us following an HMRC enquiry, due diligence finding, or internal review. We are experienced in supporting businesses both proactively and reactively at any stage.

Can you represent us in dealings with HMRC?

Yes. We regularly act as the primary point of contact with HMRC, managing enquiries, compliance checks and investigations on our clients’ behalf. This includes IR35 challenges, National Minimum Wage reviews, CIS audits and voluntary disclosures. Our role is to protect your position, limit disruption and secure proportionate and fair outcomes.

How can share schemes benefit both employers and employees?

Well-designed share schemes align employee incentives with business growth while offering significant tax efficiencies. We advise on and implement a full range of HMRC-approved and unapproved arrangements, including EMI and growth share schemes, to  ensure they meet your commercial objectives and comply fully with HMRC requirements.

What support do you offer for contractor status and IR35 risk?

Employment status is a high-risk area with significant financial exposure if managed incorrectly. We help businesses assess and structure contractor engagements, implement compliant processes and reduce IR35 risk. If HMRC challenges a contractor’s status, we manage the enquiry end-to-end and represent your interests throughout.

Do you support businesses with international employees and complex workforces?

Yes. We advise employers with internationally mobile employees, as well as those operating in high-risk compliance areas such as CIS, National Minimum Wage and benefits in kind. Our specialist knowledge ensures obligations are met across jurisdictions and sectors, while identifying opportunities to manage cost and risk effectively.

Family & Wealth

When should family and wealth tax planning advice be sought?

The most effective planning is done well in advance of major life events such as a business exit, relocation, succession, or changes in family circumstances. Early advice provides greater flexibility and more opportunities to reduce tax exposure, although we regularly support clients who require urgent guidance due to time sensitive or unexpected changes.

How can you help reduce Inheritance Tax for future generations?

We advise on a wide range of Inheritance Tax planning strategies tailored to your personal and family objectives. This may include the use of trusts, lifetime gifting, succession planning and asset structuring. Our focus is on delivering practical solutions that preserve family wealth while ensuring compliance and long-term peace of mind.

Do you advise on international and cross-border personal tax matters?

Yes. We have extensive experience advising individuals and families with international connections, including residency and domicile planning, relocation to or from the UK, and treaty relief. We help clients understand their tax obligations across jurisdictions and structure their affairs efficiently in a global context.

Can you assist during sensitive situations such as divorce or separation?

We regularly advise clients during divorce or separation, where tax considerations are often overlooked but can have a significant financial impact. Our role is to provide clear, objective advice on the tax consequences of asset division and ongoing arrangements, helping clients make informed decisions during a challenging time.

How do you work with other advisers such as accountants and lawyers?

We frequently work alongside clients’ existing accountants, solicitors and family advisers, as well as those referred to us by clients. Our approach is collaborative and non-competitive, ensuring specialist tax expertise is integrated seamlessly into the wider advisory team to achieve the best overall outcome.

VAT & Indirect

When should a business seek specialist VAT advice?

VAT advice is most valuable when a business is entering a new transaction, expanding internationally, acquiring or disposing of property, or changing its operational structure. Many clients also seek support following an HMRC query or when uncertainty arises around VAT liability or recovery. Early advice helps prevent costly errors and ensures VAT is treated correctly from the outset.

Can you help if we are already under HMRC VAT scrutiny?

Yes. We regularly support clients during HMRC VAT enquiries, audits and disputes. Acting on your behalf, we manage communications with HMRC, review your VAT position, strengthen control standards where needed, and work to achieve a fair and proportionate outcome while minimising disruption to your business.

How do you support VAT efficiency and cashflow?

We help businesses optimise VAT recovery, ensure correct VAT categorisation, and structure transactions in a way that reduces unnecessary VAT costs. By reviewing systems, processes and transaction flows, we identify opportunities to improve cashflow while remaining fully compliant with HMRC regulations.

Do you advise on international and cross-border VAT issues

Yes. International trade introduces complex VAT and customs obligations. We advise on cross-border supplies, imports and exports, European VAT considerations, and the interaction between VAT and customs duties. Our goal is to ensure transactions are structured correctly and that overseas VAT obligations are clearly understood and managed.

Do you have experience in sector-specific VAT issues?

We advise across a wide range of sectors, including land and property, corporate transactions, and travel, leisure, and hospitality. In particular, we have specialist expertise in complex regimes such as the Tour Operators Margin Scheme, where incorrect treatment can lead to significant exposure if not handled properly.

Investigations & Disputes

What should I do if HMRC contacts me about an investigation or enquiry?

You should seek specialist advice immediately, before responding substantively to HMRC. Early action can significantly influence the scope, tone and outcome of an enquiry. We can step in at any stage, take over all communication with HMRC, and ensure your position is presented accurately and defensibly from the outset.

Can you help if errors or unpaid tax have already been identified?

Yes. Many clients come to us after discovering errors or underpaid tax themselves, often following due diligence or a change of adviser. We specialise in managing voluntary disclosures, presenting the facts clearly and transparently to HMRC in a way that demonstrates cooperation and typically results in reduced penalties — or, in some cases, none at all.

How do you handle allegations of tax fraud?

Most tax fraud cases are dealt with by HMRC under civil investigation procedures. Our role is to manage these cases strategically, quantify the true tax position, and negotiate fair settlements while seeking to avoid criminal prosecution wherever possible. We do not assist in concealing wrongdoing – instead, we focus on professional disclosure and robust negotiation to achieve the best achievable outcome.

Will you deal directly with HMRC on my behalf?

Yes. Once instructed, we act as your representative and manage all interaction with HMRC. As former HMRC investigators, we understand how enquiries are conducted and how to prevent them from becoming unnecessarily wide-ranging or adversarial. Our aim is to protect you from excessive demands and ensure HMRC acts proportionately.

What makes K3 Tax Advisory different in investigation and dispute cases?

Tax investigations and disputes are a highly specialised area, and our team focuses on this work every day. With extensive ex-HMRC experience, a strong track record of reducing assessments and penalties, and a reputation for integrity with HMRC, we are trusted by both clients and professional advisers to handle high-stakes, sensitive matters with discretion and care.
