Here is the reply from IRAS to my suggestion on GST

I have posted this comment in the TodayOnline website:

I thank Claire Chua for giving me a reply, although I am somewhat disappointed with the reply. I suggest that Claire Chua gets her colleague, who is the GST expert, to contact me by email (kinlian@gmail.com) and engage in a discussion with me. A discussion has to be two way.
In her reply, Claire Chua has missed these three important points:
1. If the Finance Minister is giving $5,000 to help small companies, why not give the small advantage suggested by me, as the cost to the government  is small and the impact to the small business  is large.
2. Businesses have to keep a separate record of the GST inputs and outputs and have to show the amount separately in the tax invoices. The administrative cost is quite significant. I know, as I am involved in the work.
3. A small company supplying goods and services to a GST registered company has to reduce the price to remain competitive, and they have already incurred the GST on their inputs, which they cannot claim back. This is a serious disadvantage that compel small companies to register for GST, when they do not have to, and to incur the cost of compliance. Even IRAS finds it a nuisance to handle these small companies - based on the "body language" shown in their processes.  [Tan Kin Lian]

I found her e-mail address from the Singapore Government Directory and sent this message to her:

I invite you to ask your colleague (GST expert) to call me at 66599611 or reply to me by email to have a discussion on this matter. Do not just give a reply without understanding the issue that has been brought up.
