What Is a PAYG Withholding Variation?

By Narelle Hartigan, CPAPublished 1 July 20265 min read

A PAYG withholding variation is an application you lodge with the ATO asking it to direct your employer to withhold less tax from each pay. It suits people whose deductions reliably produce a big refund, negative gearers above all, and moves that refund into the year's pay packets instead. The application is the PAYG withholding variation application (NAT 2036), lodged online, and an approved variation runs to the end of the financial year. How withholding is worked out in the first place is in the PAYG withholding guide.

What a withholding variation is

Standard withholding assumes your salary is your taxable income. If you carry large, predictable deductions, the schedules withhold too much all year and square up with a refund the following spring. A downward variation fixes the mismatch at the source: the ATO approves your estimate, issues a notice with start and finish dates, and your employer withholds at the reduced level from the next practical pay run. Your final tax bill does not change by a cent; only its timing does.

To see what your pay would look like under a lower withholding rate, run the before and after through the PAYG withholding calculator.

Who actually uses one

The classic case: negative gearing on $95,000

Withholding on a $95,000 salary2026-27 resident rates with Medicare levy$20,920
Tax on $83,000 taxable incomeafter a $12,000 net rental loss$17,080
Tax withheld too early without a variation$3,840
Back in each fortnightly pay with a variation$148

Beyond property investors, variations turn up for people with large work-related deductions, deductible personal super contributions, or income streams that double up withholding across payers. If your withholding merely feels high rather than provably high, diagnose it first: why is my PAYG tax so high walks the usual causes.

How to apply (NAT 2036)

  1. Gather the year's estimates

    Expected salary, rental income and expenses, other deductions. The application asks you to project the full financial year.

  2. Lodge the PAYG withholding variation application

    Form NAT 2036, lodged online through ATO online services via myGov. The ATO's published processing time is 28 days for online applications and 56 days for paper.

  3. The ATO notifies you and your employer

    An approved variation comes with starting and finishing dates, and your payer adjusts withholding from the next pay cycle it can.

  4. Re-apply each year

    A variation expires at the end of the financial year unless the ATO grants a multi-year variation. Lodge the new application before the old one runs out to keep pays consistent.

The catch: estimate honestly

The variation only shifts timing, so an overcooked estimate does not create tax savings; it creates a debt at assessment. Underestimate your income, or overestimate the rental loss, and the tax not withheld during the year comes due in one hit with your notice of assessment. If your circumstances change mid-year, sold the property, rent went up, deductions fell away, tell the ATO so the variation can be adjusted rather than riding it to a bill. Used straight, it is one of the few legitimate levers covered in how to reduce PAYG tax.

Frequently asked questions

What is a PAYG withholding variation?
An ATO-approved instruction to your employer to withhold less (or occasionally more) tax from your pay, based on your estimate of the year. It moves a predictable refund into your regular pays without changing your final tax.
What form is a withholding variation?
The PAYG withholding variation application, NAT 2036, lodged online through ATO online services via myGov. The ATO lists 28 days processing for online lodgments and 56 days for paper.
How long does a variation last?
To the finishing date on your notice, at most the end of the financial year, unless the ATO grants a multi-year variation. You re-apply each year to continue it.
Does a variation reduce the tax I owe?
No. It only reduces what is withheld during the year. If the estimate was accurate you simply stop overpaying; if it was too generous you owe the difference at assessment.
Can my employer refuse to apply it?
The ATO notifies your payer directly and the varied rate applies from the next practical pay run. Employers follow the ATO notice, not your word, which is why the application goes through the ATO rather than payroll.
