The provision splits into a current portion, roughly what is owed now, and a deferred portion, which reflects timing differences and creates a deferred-tax-liability or deferred-tax-asset. Cash taxes paid are disclosed separately in the footnotes and in the cash-flow-statement.
A gap between the provision and cash taxes is normal. A persistent, widening gap is worth understanding, because it usually means accelerated deductions that will reverse later.
Example: Northwind reports a $33M provision on $132M of pre-tax income but pays $21M in cash, the $12M difference being accelerated equipment depreciation for tax that raises a deferred tax liability.
