啇業登記沒有取消，已經有七年多，現在想去取消，是不是要補錢。?

Maybe.

Your problem is bigger than it seems. For starter, since you have not paid the business registration, it is very likely that you did not file the profit tax return as required (Note - business registration = profit tax return).

So your problem is no longer money, but also other civil and criminal liability (if applicable) for your pattern of failure.

商業登記是年度的，你不付錢續證自動作廢，如果你還在使用廢證就是觸犯虛假文書罪
