NZ PAYE Due Dates Calculator

This calculator works out the exact PAYE payment and payday filing due dates for any pay run, based on IRD's employer rules. You enter your total PAYE plus ESCT deductions from the previous 12 months, which sets whether you're a monthly payer (at or under the $500,000 threshold, paying once a month on the 20th) or a twice-monthly payer (over $500,000, paying on the 20th and 5th). You also pick your filing method, electronic or paper, and the pay date for the run. The calculator returns your employer type, the payday filing due date (2 working days for electronic filers, 10 calendar days for paper IR348 filers), the PAYE, ESCT and KiwiSaver payment due date, and the tax year the run falls in. If a due date lands on a weekend or public holiday, it automatically shifts to the next working day and flags the change. A penalty table shows late payment penalties (1% the day after the due date, a further 4% after seven days, plus use-of-money interest) and late filing penalty amounts, showing what's at stake if a deadline slips. Use it to plan payroll cash flow, confirm which threshold applies to your business, or check a specific pay date. These are indicative statutory dates and penalty rates; always confirm current figures and file and pay through myIR or your payroll software.

Total PAYE and ESCT deductions sent to IRD in the last 12 months. Determines if you're a monthly or twice-monthly payer.

Pay date

The pay date determines which tax year the run falls in, and which filing/payment due date applies.

Monthly vs twice-monthly

The $500,000 threshold is based on your PAYE plus ESCT in the prior 12 months (not gross wages). For a typical NZ business, this equates to gross annual payroll of roughly $2.0m-$2.5m depending on salary mix.

Monthly payers (PAYE+ESCT ≤ $500k/year)

  • One PAYE payment per month.
  • Due on the 20th of the following month.
  • March PAYE → 20 April. April PAYE → 20 May. Etc.

Twice-monthly payers (PAYE+ESCT > $500k/year)

  • Two PAYE payments per month.
  • Pay dates 1-15 → PAYE due on the 20th of the same month.
  • Pay dates 16-end → PAYE due on the 5th of the next month.
  • Example: pay run with pay date 10 April → PAYE due 20 April. Pay run with pay date 28 April → PAYE due 5 May.

Payday filing (mandatory since 1 April 2019)

Separate from payment dates, every pay run must be filed to IRD via payday filing:

  • Electronic filers: Within 2 working days of each payday.
  • Paper filers (IR348): Within 10 calendar days of the end of the month.
  • Payday filing shows IRD gross pay, PAYE, ESCT, KiwiSaver, student loan and child support deductions for every employee each payday.
  • The traditional EMS is now auto-generated from payday files.

Weekend and public holiday shifts

If a payment or filing due date falls on a weekend or public holiday, it moves to the next working day. NZ-wide public holidays include New Year (1 and 2 January), Waitangi Day (6 February), Good Friday and Easter Monday (variable), ANZAC Day (25 April), King's Birthday (first Monday in June), Matariki (variable), Labour Day (fourth Monday in October), Christmas Day (25 December) and Boxing Day (26 December). Provincial anniversary days (e.g. Auckland Anniversary, Wellington Anniversary) also apply regionally but do NOT shift IRD due dates.

Penalties for missing a PAYE date

IRD applies an automatic 1% late payment penalty the day after the due date, plus an additional 4% seven days after the due date. Use-of-money interest accrues daily at the IRD UOMI debit rate (currently 10.88% p.a. as of 8 May 2025). Late filing penalties for payday filing are $250 if gross period earnings are under $500k, or $500 if gross is $500k or more. Repeat offences and larger employers can attract more serious sanctions.

Frequently asked questions

When does an NZ employer have to pay PAYE?

It depends on your annual PAYE and ESCT total. Small employers with PAYE plus ESCT of $500,000 or less per year pay monthly, with PAYE due on the 20th of the following month (e.g. March PAYE is due 20 April). Large employers with PAYE plus ESCT over $500,000 per year pay twice-monthly: PAYE for pay dates 1-15 is due on the 20th of the same month, and PAYE for pay dates 16-end of month is due on the 5th of the next month. If a due date falls on a weekend or public holiday, it shifts to the next working day.

What is payday filing?

Payday filing has been mandatory for all NZ employers since 1 April 2019. Rather than filing one employer monthly schedule (EMS) once a month, employers must now file payday information to IRD every time they pay staff. Electronic filers must submit within 2 working days of each payday. Paper filers must submit within 10 calendar days. The filing is separate from the payment - you still pay on the 20th (or twice-monthly dates for large employers), but the filing happens on each payday.

What is the late filing penalty for PAYE?

Non-payment penalties apply at 1% of the unpaid PAYE the day after the due date, then an additional 4% seven days after the due date. Interest accrues at the IRD use-of-money interest debit rate (currently 10.88% from 8 May 2025). Late filing penalties apply separately for payday filing: $250 if your gross earnings for the period are under $500,000, and $500 if $500,000 or more. These are per filing. Repeated late filing can escalate.

How is the $500,000 threshold measured?

The threshold is based on your PAYE plus ESCT deductions in the previous 12 months (not gross wages - just the deductions sent to IRD). If your total PAYE + ESCT withheld was $500,000 or less, you're a monthly payer for the current year. Over $500,000 moves you to twice-monthly. The threshold was raised from $100,000 to $500,000 effective 1 April 2017 to reduce compliance burden. New employers start as monthly payers and move to twice-monthly if they cross the threshold.

What happens if a due date falls on a weekend or public holiday?

The due date shifts to the next working day. For example, if 20 April falls on a Saturday, the PAYE due date becomes Monday 22 April. If 5 January falls on a Sunday and the 6th is a public holiday, the due date becomes Tuesday 7 January. This rule applies to both monthly and twice-monthly payment dates, and to payday filing deadlines. IRD's online payment system reflects the adjusted date automatically.
