Going back to basics of
Section 597AA Entrepreneur Relief ("ER") and applying it to the question posed by the OP (knowing that they are obviously going to get professional advice and this is only a general discussion):
1. ER is available to both a sole trader and a shareholder.
2. The asset being sold (upon which there is a capital gain where someone is claiming ER) must be a "Chargeable Business Asset" (CBA). A CBA is, either:
(i) an asset (including goodwill) used for the purposes of a "qualifying business" carried on by an individual (i.e. this applies to a sole trader), or
(ii) a holding of ordinary shares in a company whose business consists wholly or mainly of carrying on a "qualifying business" (i.e. this applies to a company owner).
3. A CBA does
not include securities or other assets held as investments, development land etc.
4. What is a qualifying business? A qualifying business means a business other than the holding of securities or other assets as investments, the holding of development land, or the development or letting of land.
At this point, where are we?
If I am an individual and I buy Apple shares and realise a capital gain, can I get ER on the gain? No - due to point 3 above. If I own a commercial building or residential premises which I let out, sell it and realise a capital gain, I cannot get ER for the same reason. The Apple shares and the letting premises are not CBAs.
If I am a sole trader operating a newsagent business and I sell my business consisting of the premises I operated out of and maybe some goodwill, I should be able to get ER on the disposal of both assets (premises and goodwill) as the premises was used for the business - it is not an investment asset. The premises and goodwill are CBAs.
What if I start a 'capital-light' LTD company that provides consulting services? The company earns €100k p.a. in after-tax profits. There are practically no fixed or current assets - the company employee performs the company's business using a laptop and a Zoom subscription. Money builds up in the company bank account. After 10 years I want to liquidate the company. €1m has accumulated in cash over the period. If I was to liquidate the company, my capital gain is c.€1m (let's assume I started it with little or no equity). Can I get ER on that gain?
Going back to the numbered points earlier:
- Per point 2, are the shares that I am disposing of a CBA? We know it's a "holding of ordinary shares".
- Is the company's business wholly or mainly of carrying on a "qualifying business"? A qualifying business means a business other than the holding of securities or other assets as investments, the holding of development land, or the development or letting of land.
- The company is not buying and selling securities or land. I, as an employee of the company, work 40 hours a week consulting for several clients which the company invoices. The clients pay the invoiced amounts into the company bank account. The company's business is plainly, and by any reasonable measure "
a business other than the holding of securities or other assets as investments, the holding of development land, or the development or letting of land." It's a consulting services firm.
- The company is not obliged to use the company funds to procure assets such as property, equipment or inventory.
Getting back to the question the OP posed, I know we can caveat, insert provisos, and suck air in through our teeth about this until the cows come home, but to suggest that if a bank paid the company
any interest on the cash in it's account, or that the company, having accumulated €1m in cash from its trade over the years, is now somehow an investment company, and cannot be considered to be carrying on a qualifying business so that ER would be null and void for the company owner, is a bit mad.
