Thomas Consulting was established to provide specialist tax consulting services to family law firms. At Thomas Consulting we understand the multifaceted regulatory environment in which law firms operate and we aim to provide straightforward advice on complicated UK tax issues. Relationship breakdown can lead to a myriad of tax implications, including capital gains tax and stamp duty land tax.

We aim to place to ourselves discretely by your or your clients side to offer either one off or ongoing support during the process.  We are a boutique specialist firm, meaning that we can act quickly and have a strong underlying knowledge of your world and what it is you need from us.

Tax Implications on Family Breakdown

Co-written by a leading tax expert, Sofia Thomas and top family lawyer, James Pirrie, Tax Implications on Family Breakdown provides answers to the common problems encountered in financial remedy cases, in a way that will assist professionals from each discipline.

Family law practitioners will find a grounding in tax to help them to spot issues that arise upon family breakdown or financial remedies proceedings, whilst tax practitioners will gain the knowledge needed on tax implications in family separation to maintain an in-house practice in this area. In addition, it enables these practitioners to engage successfully to ensure that all necessary information is available to the court, or within alternative dispute resolution processes.

Flow charts, checklists and step-by-step chapters breakdown complex information, and precedent material is included to engage the ‘Part 25’ expert with maximum safety and efficiency.

Frequently Asked Questions

Do you do mediation work?

Yes, Sofia can sit in on mediations to assist with any tax queries which may arise during the day. Depending on the length and complexities of the discussions Sofia can either attend a full day or part of the day.  For those clients with simpler tax issues, Sofia can also attend via conference call.

During the mediation Sofia will be able to advise on potential tax implications to provide accurate and up to date figures for a range of taxes.  In our experience this has proved extremely valuable as it has enabled the negotiations to continue with consideration of the tax implications.  These sessions are not appropriate for in-detail complex tax planning but they are incredibly useful for individuals who are considering several options on the day.

As part of mediation services, Sofia will provide a complete follow-up report  detailing all of the tax advice given during the meeting. These are completed usually within 3 working days of the mediation.

Costs for mediation work start at £350 + VAT per hour or a full day from £2,000 + VAT (plus travel costs if outside of London).

Does Sofia provide in-house tax expertise?
