會計問題(核數報告)

取回二份或三份都無大問題，因為一份釘好給客睇，另一份公司存檔。

I think you have to check HOW MANY orginal copies of the audited financial statements the directors have signed. Normally, the CPA only retain 1 copy for their record and 1 for Inland Revenue Department under the Profits Tax. Assuming you have given 4 copies of this original signing copies to the CPA, you could then get back 2 copies of the original financial statements with the signed auditors' report attached.
Generally speaking, you can have all original signed copies back except the 2 copies as one retained by CPA for his record and one for profits tax purposes if the CPA is also acting as a tax representative of your company. It is a matter of mutual agreement for how many copies you want at a cost charged by your CPA. There is no hard and fast rule for how many copies to be given back by a CPA.
