Provisional tax helps you manage your income tax by paying it in instalments during the year. It lets you "spread the load" and avoid having a big amount to pay at the end of the year.
If your residual income tax (tax to pay) from your last income tax return was more than $2,500, you will have to pay provisional tax for the following year.
