如何寫英文信去稅局要求暫停交商業登記費

According to IRD, if you cease your business you must notify the Business Registration Office in writing within 1 month of the date of cessation. Alternatively, you may furnish the details on the form IRC 3113. Furthermore, the business registration fee must be paid up to and including the year in which the business has ceased.

So, you should pay the business registration fee coming due. The approval of withholding is unlikely. After the company ceases business, you may file form IRC 3113 instead of writing an English letter.

You are talking about the cessation of business of a limited company going to be de-registered in Companies Registry. Please go to the follwoing web-site for "How to Apply Notice of No Objection to a Company Being Deregistered" by completing the Application Form (IR 1263);
