Some of the questions were easy to answer, simple matters of fact or points that that were well documented in his impeccable filing system.
Others were more difficult. He had for example destroyed old insurance policies and evidence of membership of social and sporting bodies.
One particular item sticks in my memory, partly because of the incredulity it prompted: “personal correspondence and photographs to help me understand your background, lifestyle and future intentions”. He was equally offended by a question regarding his religious, cultural and social connections. “How far,” he asked “can they intrude on my private life?”.
Ultimately, we did find enough information to satisfy HMRC and to close the enquiry. I warned Franz to keep all of the documents we had gathered and suggested others to keep in future, as I strongly suspected that the issue would be raised again within a short time. Neither of us wanted a repeat of the intrusive, time consuming, stressful and disruptive evidence-gathering exercise we had just been through.
That call to action proved, however, to be redundant as Franz died the following year.
A charming, fascinating and meticulous man who reinforced in my mind the importance of understanding that not all documents relevant for tax are financial – and of ensuring that they are identified and kept securely in anticipation of the day they may be needed. Knowing the client as a person makes it far easier to guide them through the tax labyrinth.
