Yes. It works very well. I have been using it for the last couple of years - since July 2009.
I use it for monthly VAT returns, but it also has space for annual income tax return.
Very convenient instead of queuing at Times Towers... You simply do the return in your office, file it in, print out a payment slip and take the money to the bank. That's it.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
