Primary Tax Code — 'M SL'

What Is Tax Code 'M SL'?

An employee is to use the M SL tax code if they meet a combination of the following criteria, and also HAVE a student loan:

  • They receive an income-tested benefit.
  • This job is their main or highest source of income.
  • They are New Zealand tax residents.
  • Their annual income is unlikely to be between NZ$ 24,000 and NZ$ 48,000.
  • Either they or their partner receive Working for Families Tax Credit.



Meg works after-school at a grocery store. She works 3 hours a day, 5 days a week, and for an annual income of NZ$ 13,000. This is Meg’s only job, but she pays student loan as well so she uses the M SL tax code.


NOTE: Only one primary tax code can be used.


If your employee is under the wrong tax code, they're going to end up with a big tax bill at the end of the year. Ensure that your workers notify you whenever their circumstances change.
