Dear Andrew Mardon
Thank you for your request made under the Official Information Act 1982 (OIA), received on 8
June 2026. You requested the following:
I am requesting the total amount of tax written off for PAYE earners who would otherwise
have had a balance owing because of an additional pay period falling within the tax year.
An annual total for each tax year since 2020 (or the year of the policy's inception) will be
fine.
Background
Extra pay periods can occur because a calendar year of 365 or 366 days does not divide evenly
into weekly, fortnightly, or four-weekly pay cycles. Where a payday falls on the first day of the
tax year, this can result in an additional payday within that year. In some cases, this may mean
too little pay as you earn (PAYE) tax is deducted for that tax year, even though PAYE was
correctly withheld under the applicable rules.
To support the integrity and fairness of the tax system, the Tax Administration Act 1994 (TAA)
makes provision for tax arising solely from an extra pay period to be written off. The relevant
parts of the TAA are section 22J(1) and clause 1(c) of schedule 8, part B. These write-off rules
were introduced to reduce compliance costs and ensure that individuals who have done
everything they reasonably could to meet their obligations are not surprised by a tax bill at year-
end.
Inland Revenue may write-off your tax bill if you are a qualifying individual, whose income is
already reported to Inland Revenue and has tax deducted before they receive it, and your tax
bill has arisen
solely because of an extra pay period. This is subject to certain factors, such as
(but not limited to) you have not received Working for Families Tax Credits, you have not
changed your tax code or used a tailored tax code during the year. Information publicly available
on Inland Revenue’s website provides further information on write-offs for extra pay periods:
Automatic write-offs.
Information released
The information you requested is set out in the table on the following page. It was extracted
from our systems on 18 June 2026 and reflects a point-in-time snapshot. Please note that all
2026 figures are provisional and may change as 2026 Income Tax Assessments are finalised.
The total write-off value shown represents amounts written off for customers identified as having
received an extra pay period, resulting in tax payable that was subsequently written off. To
provide further context, data on the number of affected customers has also been included.

Note: write-off ($m) values are rounded to one decimal place.
Variations in write-off totals between tax years largely reflect how the day each tax year starts
and ends aligns with regular pay cycles, changing the number of customers eligible for write-
offs year to year. For example, government pay cycles are typically fortnightly, running from
Wednesday (day 1) to Tuesday (day 14). In 2025, the tax year ended on a Monday, while in
2026 it ended on a Tuesday.
We note that higher numbers of customers received an extra pay period write-off (<$50) in the
2020 tax year in comparison to the other years. This is attributable to the fact that some New
Zealand superannuation recipients received an additional pay period during that year.
Right of review
If you disagree with my decision on your OIA request, you have the right to ask the Ombudsman
to investigate and review my decision under section 28(3) of the OIA. You can contact the office
of the Ombudsman by email a

Publishing of OIA response
We intend to publish our response to your request on Inland Revenue’s website
(ird.govt.nz) as
this information may be of interest to other members of the public. This letter, with your personal
details removed, may be published in its entirety. Publishing responses increases the availability
of information to the public and is consistent with the OIA's purpose of enabling more effective
participation in the making and administration of laws and policies and promoting the
accountability of officials.
Thank you again for your request.
Yours sincerely
