Hi Nancy
Yes, you can get a tax clearance no matter what tax type you are registered for.
I would seek advice about registering for turnover tax though. Personal service companies are exempt from registering for turn over tax and from yiur description it sounds like you might qualify as a personal service entity. Also, in catering you might have significant over head costs such a stock, staff, fuel, etc and these would not be deductable if you registered for turnover tax.
I'd be happy to give you some more detailed advice in this regard if you'd like to drop me a mail at This email address is being protected from spambots. You need JavaScript enabled to view it.. No obligations ans no charge of course.
