PAYE 2026 -- Simple Guide

A plain-language guide to understanding and calculating Pay-As-You-Earn (PAYE) income tax in 2026.


What is PAYE?

PAYE stands for Pay-As-You-Earn. It is income tax that your employer takes out of your pay before you receive it, and sends to the government on your behalf.
Not all of your pay is taxed. The government gives you a tax-free portion -- an amount you can earn each period without paying any tax. Only the pay above that tax-free portion is taxed.


The Key Numbers You Need

PAYE uses three important numbers. They depend on how often you are paid.
Pay frequency
Tax-Free Amount
25% Bracket Limit
High-Earner Threshold
Monthly
$140,000
$280,000
$420,000
Bimonthly
$70,000
$140,000
$210,000
Fortnightly
$64,615
$129,231
$193,846
Weekly
$32,308
$64,615
$96,923
Here is what each one means:
  • Tax-Free Amount -- the portion of your pay that is not taxed at all. If your total pay is at or below this number, you pay zero PAYE.
  • 25% Bracket Limit -- the maximum amount of taxable pay that is taxed at the lower 25% rate. Anything above this is taxed at 35%.
  • High-Earner Threshold -- if your total pay exceeds this number, a special rule changes how your tax-free amount is calculated (explained later).


Tax Rates

There are two tax rates:
Rate
When it applies
25%
On the first portion of your taxable pay (up to the 25% Bracket Limit)
35%
On anything above the 25% Bracket Limit
Think of it like two buckets. Your taxable pay fills the first bucket (25% rate) until it is full. Any overflow spills into the second bucket (35% rate). You pay 25% on the first bucket and 35% on the second.


How to Calculate PAYE (Step by Step)

Follow these steps in order. If your pay does not include overtime, a second job, or children, you can skip Steps 2 and 3.

Step 1 -- Start with your gross pay

This is your total pay for the period before any deductions. It includes your basic salary, allowances, bonuses, overtime, and any other taxable income.

Step 2 -- Subtract tax-free overtime (if any)

The government allows up to $50,000 per month in overtime to be tax-free. If you earned overtime this period, subtract the tax-free portion from your gross pay.
  • If your overtime is $50,000 or less for the month, all of it is tax-free.
  • If your overtime exceeds $50,000 for the month, only $50,000 is tax-free. The rest counts as taxable pay.
If you are paid more than once a month, the $50,000 is shared across all your pay periods in that month. For example, if you used $30,000 of tax-free overtime in the first fortnight, only $20,000 remains for the second fortnight.
Adjusted pay = gross pay minus tax-free overtime

Step 3 -- Subtract your NIS contribution, private insurance, and child allowance

Your NIS contribution (calculated using the  NIS guide ) is subtracted from your pay before tax. If you pay for life insurance or health insurance through your employer, your employee portion is also subtracted. See the  Insurance and PAYE 2026 Simple Guide  for details on what counts and what is taxable vs non-taxable.
If you have children under 18, you also get a child allowance -- an extra amount subtracted per child, per period:
Pay frequency
Child allowance per child
Monthly
$10,000
Bimonthly
$5,000
Fortnightly
$4,615
Weekly
$2,308
Add your NIS contribution, life insurance, health insurance (employee portions only), and your total child allowance together. This combined amount is subtracted from your adjusted pay.
Pay after deductions = adjusted pay minus NIS minus life/health insurance minus total child allowance

Step 4 -- Subtract the tax-free amount

Now subtract the tax-free amount for your pay frequency (from the table above).
Chargeable income = pay after deductions minus tax-free amount
"Chargeable income" is the amount that is actually taxed. If this number is zero or negative, your PAYE is $0 -- you owe no tax this period.

Step 5 -- Apply the tax rate(s)

Now apply the tax rates to your chargeable income.
If your chargeable income is within the 25% Bracket Limit:
PAYE = chargeable income x 25%
If your chargeable income exceeds the 25% Bracket Limit:
Split it into two parts:
First part (lower bracket) = 25% Bracket Limit x 25%
Second part (upper bracket) = (chargeable income minus 25% Bracket Limit) x 35%
PAYE = first part + second part


The High-Earner Rule (One-Third Rule)

If your gross pay (after subtracting tax-free overtime) is above the High-Earner Threshold, the tax-free amount changes. Instead of the fixed tax-free amount, your tax-free amount becomes one-third of your pay.
This means high earners get a different (usually larger) tax-free amount, but they also face the 35% rate on more of their income.
If your adjusted pay is above the High-Earner Threshold:
Tax-free amount = adjusted pay divided by 3
Everything else stays the same -- you still subtract NIS, child allowance, and the tax-free amount, then apply 25% and 35% as usual.


Overtime Rules in Detail

The government gives you a $50,000 per month tax-free allowance on overtime pay. Here is how it works:
  • Monthly employees: Simple. Up to $50,000 of overtime each month is tax-free.
  • Fortnightly, bimonthly, or weekly employees: The $50,000 is shared across all pay periods in the same month.

How the sharing works

Imagine you have a $50,000 "overtime allowance" budget for the month. Each time you get paid, you use some of it. Whatever you used is gone. The rest carries forward to the next period in the same month.
Example -- Fortnightly employee with $30,000 overtime each fortnight:
Fortnight
Overtime
Budget remaining
Tax-free overtime
Taxed overtime
1st
$30,000
$50,000
$30,000
$0
2nd
$30,000
$20,000
$20,000
$10,000
Total tax-free overtime for the month: $50,000. The budget is fully used.
Example -- Weekly employee with $20,000 overtime each week (4-week month):
Week
Overtime
Budget remaining
Tax-free overtime
Taxed overtime
1
$20,000
$50,000
$20,000
$0
2
$20,000
$30,000
$20,000
$0
3
$20,000
$10,000
$10,000
$10,000
4
$20,000
$0
$0
$20,000
Total tax-free overtime for the month: $50,000. After that, all overtime is taxed.
The same $50,000 monthly limit also applies to second job income.


Child Allowance in Detail

If you have children under 18, each child reduces the amount of your pay that is taxed. The allowance is a fixed amount per child per pay period.
Pay frequency
Per child, per period
Monthly
$10,000
Bimonthly
$5,000
Fortnightly
$4,615
Weekly
$2,308
Example: You are paid monthly and have 2 children under 18.
Total child allowance = 2 x $10,000 = $20,000
This $20,000 is added to your NIS contribution and subtracted from your pay before calculating tax.
If a child turns 18 during the year, their allowance stops from the period after their birthday.


Worked Examples

Example 1: Monthly Employee -- $300,000, No Overtime, No Children

Given:
  • Gross pay: $300,000
  • NIS (employee): $15,680 (from the NIS guide: $280,000 cap x 5.6%)
  • No overtime, no children
Step 1 -- Gross pay = $300,000
Step 2 -- No overtime to subtract. Adjusted pay = $300,000.
Step 3 -- Subtract NIS.
Pay after deductions = $300,000 - $15,680 = $284,320
Step 4 -- Is the adjusted pay above the High-Earner Threshold ($420,000)? No ($300,000 is below $420,000). So use the standard tax-free amount of $140,000.
Chargeable income = $284,320 - $140,000 = $144,320
Step 5 -- Is the chargeable income within the 25% Bracket Limit ($280,000)? Yes ($144,320 is below $280,000). So all of it is taxed at 25%.
PAYE = $144,320 x 25% = $36,080


Example 2: Fortnightly Employee -- $146,031, No Overtime, No Children

Given:
  • Gross pay: $146,031
  • NIS (employee): $7,840 (from the NIS guide)
  • No overtime, no children
Step 1 -- Gross pay = $146,031
Step 2 -- No overtime. Adjusted pay = $146,031.
Step 3 -- Subtract NIS.
Pay after deductions = $146,031 - $7,840 = $138,191
Step 4 -- Is $146,031 above the High-Earner Threshold ($193,846)? No. Use the standard tax-free amount of $64,615.
Chargeable income = $138,191 - $64,615 = $73,576
Step 5 -- Is $73,576 within the 25% Bracket Limit ($129,231)? Yes. All at 25%.
PAYE = $73,576 x 25% = $18,394


Example 3: Fortnightly High Earner -- $250,000

Given:
  • Gross pay: $250,000
  • NIS (employee): $7,840
  • No overtime, no children
Step 1 -- Gross pay = $250,000
Step 2 -- No overtime. Adjusted pay = $250,000.
Step 3 -- Subtract NIS.
Pay after deductions = $250,000 - $7,840 = $242,160
Step 4 -- Is $250,000 above the High-Earner Threshold ($193,846)? Yes. Use the one-third rule.
Tax-free amount = $250,000 / 3 = $83,333
Chargeable income = $242,160 - $83,333 = $158,827
Step 5 -- Is $158,827 within the 25% Bracket Limit ($129,231)? No. Split into two brackets.
First part (25% bracket) = $129,231 x 25% = $32,308
Second part (35% bracket) = ($158,827 - $129,231) x 35% = $29,596 x 35% = $10,359
PAYE = $32,308 + $10,359 = $42,667


Example 4: Monthly Employee with Overtime -- $290,000 Base + $60,000 Overtime

Given:
  • Base pay: $290,000
  • Overtime: $60,000
  • Gross pay: $350,000
  • NIS (employee): $15,680
  • No children
Step 1 -- Gross pay = $350,000
Step 2 -- Subtract tax-free overtime. The monthly limit is $50,000. Overtime is $60,000, so only $50,000 is tax-free. The remaining $10,000 stays as taxable pay.
Adjusted pay = $350,000 - $50,000 = $300,000
Step 3 -- Subtract NIS.
Pay after deductions = $300,000 - $15,680 = $284,320
Step 4 -- Is $300,000 above the High-Earner Threshold ($420,000)? No. Use the standard tax-free amount of $140,000.
Chargeable income = $284,320 - $140,000 = $144,320
Step 5 -- Is $144,320 within the 25% Bracket Limit ($280,000)? Yes.
PAYE = $144,320 x 25% = $36,080


Example 5: Weekly Employee -- $70,000

Given:
  • Gross pay: $70,000
  • NIS (employee): $3,920 (from the NIS guide)
  • No overtime, no children
Step 1 -- Gross pay = $70,000
Step 2 -- No overtime. Adjusted pay = $70,000.
Step 3 -- Subtract NIS.
Pay after deductions = $70,000 - $3,920 = $66,080
Step 4 -- Is $70,000 above the High-Earner Threshold ($96,923)? No. Use the standard tax-free amount of $32,308.
Chargeable income = $66,080 - $32,308 = $33,772
Step 5 -- Is $33,772 within the 25% Bracket Limit ($64,615)? Yes.
PAYE = $33,772 x 25% = $8,443


Example 6: Bimonthly Employee -- $160,000

Given:
  • Gross pay: $160,000
  • NIS (employee): $7,840
  • No overtime, no children
Step 1 -- Gross pay = $160,000
Step 2 -- No overtime. Adjusted pay = $160,000.
Step 3 -- Subtract NIS.
Pay after deductions = $160,000 - $7,840 = $152,160
Step 4 -- Is $160,000 above the High-Earner Threshold ($210,000)? No. Use the standard tax-free amount of $70,000.
Chargeable income = $152,160 - $70,000 = $82,160
Step 5 -- Is $82,160 within the 25% Bracket Limit ($140,000)? Yes.
PAYE = $82,160 x 25% = $20,540


Example 7: Fortnightly Employee with Overtime -- $120,000 Base + $30,000 Overtime (First Fortnight)

Given:
  • Base pay: $120,000
  • Overtime: $30,000
  • Gross pay: $150,000
  • NIS (employee): $7,840
  • No children
  • This is the first fortnight of the month, so the full $50,000 overtime budget is available.
Step 1 -- Gross pay = $150,000
Step 2 -- Subtract tax-free overtime. Budget remaining = $50,000. Overtime = $30,000, which is less than $50,000, so all $30,000 is tax-free.
Adjusted pay = $150,000 - $30,000 = $120,000
Step 3 -- Subtract NIS.
Pay after deductions = $120,000 - $7,840 = $112,160
Step 4 -- Is $120,000 above the High-Earner Threshold ($193,846)? No. Use the standard tax-free amount of $64,615.
Chargeable income = $112,160 - $64,615 = $47,545
Step 5 -- All at 25%.
PAYE = $47,545 x 25% = $11,886
The overtime budget now has $50,000 - $30,000 = $20,000 remaining for the second fortnight.


Example 8: Monthly Employee with 2 Children -- $300,000

Given:
  • Gross pay: $300,000
  • NIS (employee): $15,680
  • 2 children under 18
  • No overtime
Step 1 -- Gross pay = $300,000
Step 2 -- No overtime. Adjusted pay = $300,000.
Step 3 -- Subtract NIS and child allowance.
Child allowance = 2 children x $10,000 = $20,000
Total deductions = $15,680 (NIS) + $20,000 (children) = $35,680
Pay after deductions = $300,000 - $35,680 = $264,320
Step 4 -- Is $300,000 above the High-Earner Threshold ($420,000)? No. Use the standard tax-free amount of $140,000.
Chargeable income = $264,320 - $140,000 = $124,320
Step 5 -- Is $124,320 within the 25% Bracket Limit ($280,000)? Yes.
PAYE = $124,320 x 25% = $31,080
Without the child allowance, the PAYE would have been $36,080 (see Example 1). The two children saved this employee $5,000 in tax.


Example 9: When Pay Is Too Low for PAYE

Given:
  • Gross weekly pay: $30,000
  • Tax-free amount (weekly): $32,308
Your gross pay ($30,000) is less than the tax-free amount ($32,308).
PAYE = $0
You owe no tax this period.


Example 10: Monthly Employee -- $500,000 (High Earner, Both Brackets)

Given:
  • Gross pay: $500,000
  • NIS (employee): $15,680 (from the NIS guide: $280,000 cap x 5.6%)
  • No overtime, no children
Step 1 -- Gross pay = $500,000
Step 2 -- No overtime. Adjusted pay = $500,000.
Step 3 -- Subtract NIS.
Pay after deductions = $500,000 - $15,680 = $484,320
Step 4 -- Is $500,000 above the High-Earner Threshold ($420,000)? Yes. Use the one-third rule.
Tax-free amount = $500,000 / 3 = $166,667
Chargeable income = $484,320 - $166,667 = $317,653
Step 5 -- Is $317,653 within the 25% Bracket Limit ($280,000)? No. Split into two brackets.
First part (25% bracket) = $280,000 x 25% = $70,000
Second part (35% bracket) = ($317,653 - $280,000) x 35% = $37,653 x 35% = $13,179
PAYE = $70,000 + $13,179 = $83,179

Summary

PAYE is income tax deducted from your pay by your employer. To calculate it:
    Start with your gross pay.
    Subtract any tax-free overtime (up to $50,000 per month, shared across pay periods).
    Subtract your NIS contribution, life/health insurance (employee portions), and any child allowance.
    Subtract the tax-free amount for your pay frequency.
    What remains is your chargeable income. Tax the first portion at 25% and anything above the 25% Bracket Limit at 35%.
If you earn above the High-Earner Threshold, your tax-free amount changes to one-third of your pay instead of the fixed amount.
If your pay is less than the tax-free amount, you pay no PAYE.
