To who? How?

If you can't find a buyer, then close it down and sell the assets. The point being that if your business isn't capable of raising capital equivalent to 1% of its taxable value, then this generally isn't a reasonable business.

The valuation for tax purposes of unlisted companies is the taxable valuation of the company assets excluding goodwill [1]. In practice this usually means the taxable value of e.g. a startup tends to be quite low.
