File a return to claim tax a refund
Sometimes the payroll wage tax exceeds your income tax liability (if you have child under 12, in case of home-ownership or personal tax deductions, or if top tax rate was withheld on bonus payment). If the prepaid tax exceeds your liability, the excess can be claimed back by filing an income tax return. More information can be found here.

Interest charge in tax assessments
If your tax assessment is issued before July 1 of the year following to the concerning tax year, no interest is charged. If your return is filed before May 1 of that year, the Dutch tax authorities in general issue a tax assessment prior to July 1 - so without charging interest.
If your return is filed later and your tax assessment is issued after July 1, the Dutch tax authorities charge interest for up to 3 months from filing date + period to payment deadline. The applicable interest rates can be found here.
If the Dutch tax authorities fail to issue a refundable assessment within 3 months from filing, they will reimburse interest as per 3 months from filing date until the assessment is issued.
Take in mind that tax liability arises during the year prior to filing an income tax return.
It is possible to file a provisional tax return and to settle the tax finances up front.
