If you have chosen to file your tax return online rather than on paper, you have an additional two weeks to file your tax return, but D-day is tomorrow, 15 July. You still have plenty of time, in theory but you should expect that things may not run as smooth as they should.
Chances are you will be competing with 60,000 other taxpayers who like to file at the last minute. The Ministry of Finance is ready for them, but the system is likely to be slowed down and you may well run into technical problems.
The Finance Ministry anticipates that these last days are red days, in terms of traffic on the website, with Wednesday being a particularly black day.
