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).
