1) You might want to take a look at the budget announcement for
the details, off hand there are the GST rebate which you mention,
special grant for education and upgrading reduction of road tax,
new circle line, new highway, etc.
2) Although Singapore reserves is growing, but the world is also
getting richer. As an open economy, Singapore is most vulnerable to
external shock which can cripple Singapore plan to be a financial
hub in this region. Hence our plan of building up a healthy reserve
is right one and so far it has served us well.
3) Yes, the timing of the GST and minister pay rise is not good,
but I have reason to believe that this is an coincidental event
which have been planned for long time ago, or it has been long
overdue due to the GE.
4) In order to qualify for GST return, you have to spend a minimum
sum on a single receipt. And expenditure such as F&B, hotels,
entertainment, transportation, are not allowed for GST
rebate.
