Case Study: How a Manufacturing Founder Reduced His Annual Tax Bill by 73%

The founder — I will call him David — came through the audit in the summer of 2023. He had been running a manufacturing business in Birmingham for eighteen years. Turnover of £4.2 million. Pre-tax profit of £800,000. He was extracting £350,000 annually in dividends and paying £118,000 in dividend tax. His accountant had told him this was the optimal structure.

It was not optimal. It was the default.

The position before

David had one trading company. No holding company. No constitutional architecture. All profit was extracted personally as a combination of salary at the NI threshold and dividends above it. His effective tax rate on the dividends was 33.75%. His IHT exposure on the business — which was worth approximately £3.8 million — was partially covered by Business Property Relief, but his personal assets (a property portfolio worth £1.2 million and cash savings of £400,000) were fully exposed.

His total annual tax bill: approximately £150,000 in income and dividend tax, plus an estimated £640,000 in IHT exposure on his non-BPR assets.

The architecture installed

Over a period of eight months, the following structure was put in place:

First, an Equity Exchange Vehicle was used to insert a holding company above the trading company without triggering CGT. The holding company took 100% of the shares in the trading company. HMRC clearance was obtained in advance.

Second, the holding company was constituted as a governed entity with a formal investment mandate. A defined proportion of trading company profits was to be retained at the holding company level annually rather than extracted personally.

Third, a Family Investment Company was established within the constitutional architecture, with David holding voting shares and his two adult children holding non-voting economic shares. Shares in the FIC were gifted to the children, starting the seven-year IHT clock.

Fourth, the constitutional document — the SAFO governance framework — was drafted by specialist commercial barristers and submitted to HMRC for advance clearance.

The position after

David now extracts £150,000 annually — enough to live on, at a tax rate of approximately 27% on the combination of salary and basic-rate dividends. The remaining £650,000 of annual profit is retained inside the holding company at 25% corporation tax. His annual tax bill: approximately £40,000 — a reduction of 73%.

The IHT position has changed structurally. Future growth in the business accumulates inside the constitutional architecture rather than inside his estate. The FIC shares gifted to his children are outside his estate after seven years. His non-BPR assets are being addressed through the trust arrangements within the SAFO framework.

The structure did not change what David earns. It changed where the income lands — and that changed everything.
