To achieve the significant tax advantage of selling to an employee ownership trust, you will need to sell a majority stake to the employee ownership trust.
However, if the tax advantage is not the key driver, you may sell a smaller percentage, and consider passing ownership to an EOT on a phased basis.
If you are selling a majority stake but not 100%, you should consider that the tax benefit of zero tax is only available on the initial sale, and subsequent sales of shares will have a tax cost.
This is a complex decision, we can support you in considering this decision, as it not only impacts the initial transaction, but can have a continuing and significant impact on the business and the EOT for many years.
