The amount of repayment obligation for a tax year that is overdue.

A scheme which allows employees to donate money to an approved donee organisation (an organisation that has Inland Revenue-approved donee status) of their choice by having a deduction taken direct from their gross pay and receive immediate tax credits that reduce their PAYE payable.

|Percentage of payments made on time|
The percentage of late payments to the total number of payments per tax year.
|Percentage of returns filed on time|
The percentage of late filings to the total number of filings per tax year.

Registered customers include all customers registered with Inland Revenue, either individuals or entities. Registered customers include some entities and people no longer active.
Revenue collected includes only taxes and duties collected by Inland Revenue. GST collected by the New Zealand Customs Service is excluded. Numbers are unconsolidated.
Note: The Treasury publishes monthly financial statements prepared on a consolidated basis, meaning they eliminate tax transactions between departments, state-owned enterprises and Crown entities.

Revenue collected from liable parents includes all revenue collected during each tax year by Inland Revenue including payments related to other time periods.
A penalty imposed as a percentage of a tax shortfall (a deficit or understatement of tax), resulting from certain actions on the part of a taxpayer. Shortfall penalties apply to most taxes and duties, including student loans, but not to child support repayments by liable parents.
The law divides these actions into five categories of fault or breach, with a specified penalty rate for each category. The severity of the penalty increases in proportion to the seriousness of the breach: Not taking reasonable care (20%), Unacceptable tax position 20%, Gross carelessness (40%), Abusive tax position (100%), Evasion (150%).
