Answer:
However you wind up the company, dividends tax is payable on the retained earnings. You can’t get them out of the company in any other way. So whether you transfer the retained earnings to the loan account to set the two off, or have the shareholder repay the loan so that the company can use the cash to pay the liquidation dividend, the dividends tax will be payable.
You’ve answered your own question when you state that the loss from failure to claim the loan would be added back for tax purposes. Think about it; the adding back would restore the retained earnings balance for tax purposes, and there you’d have the dividends tax liability still with you.
