Comprehensive Guide to ATO PAYG Calculator 2019 (Excel Version)
The 2018-2019 financial year introduced several important changes to Australia’s Pay As You Go (PAYG) withholding system. This guide explains how the ATO PAYG calculator worked during that period, how to use our interactive tool, and what you need to know about Excel-compatible calculations.
Understanding PAYG Withholding in 2018-2019
PAYG withholding is the system where employers withhold tax from payments made to employees and other workers. The amounts withheld are then sent to the ATO as credit against the worker’s end-of-year tax liability. The 2018-2019 financial year (1 July 2018 to 30 June 2019) had specific tax tables that determined how much should be withheld.
Key Changes in 2018-2019
- Tax rates unchanged: The marginal tax rates remained the same as 2017-2018, with the top marginal rate of 45% applying to incomes over $180,000.
- Low and Middle Income Tax Offset (LMITO): Introduced in the 2018-19 Budget, providing tax relief of up to $530 for individuals.
- Medicare levy threshold increase: The family threshold increased to $37,089.
- Superannuation guarantee: Remained at 9.5% (same as previous year).
How the ATO PAYG Calculator Works
The ATO’s PAYG withholding calculator uses specific formulas based on:
- Payment period: Weekly, fortnightly, monthly or annual
- Gross payment amount: The total payment before tax
- Tax-free threshold: Whether the employee has claimed it
- Residency status: Australian resident or foreign resident
- HECS/HELP debt: If the employee has a study debt
- Additional withholding: Any extra amount the employee wants withheld
2018-2019 PAYG Withholding Tax Tables
The following tables show the withholding amounts for residents (excluding HECS/HELP) for different payment periods in 2018-2019:
| Weekly Earnings | Withholding Amount | Marginal Tax Rate |

Excel-Compatible Calculations
If you need to perform these calculations in Excel, you can use the following formulas based on the ATO’s schedules:
For weekly payments with tax-free threshold:
=IF(A1<=180, 0,
IF(A1<=370, (A1-180)*0.19,
IF(A1<=870, 35.7+(A1-370)*0.325,
IF(A1<=1800, 218.2+(A1-870)*0.37,
542.3+(A1-1800)*0.45)))))
For monthly payments with tax-free threshold:
=IF(A1<=780, 0,
IF(A1<=1600, (A1-780)*0.19,
IF(A1<=3760, 154.4+(A1-1600)*0.325,
IF(A1<=7820, 945.9+(A1-3760)*0.37,
2354.7+(A1-7820)*0.45)))))
HECS/HELP Repayment Calculations
In 2018-2019, HECS/HELP repayments were calculated based on your income thresholds:
| Repayment Income | Repayment Rate |
|---|---|
| Below $51,957 | 0% |
| $51,957 - $58,954 | 2% |
| $58,955 - $66,534 | 4% |
| $66,535 - $74,727 | 4.5% |
| $74,728 - $83,526 | 5% |
| $83,527 - $92,906 | 5.5% |
| $92,907 - $102,866 | 6% |
| $102,867 - $113,406 | 6.5% |
| $113,407 - $124,525 | 7% |
| $124,526+ | 8% |
To calculate your HECS repayment in Excel:
=IF(A1<=51957, 0,
IF(A1<=58954, A1*0.02,
IF(A1<=66534, A1*0.04,
IF(A1<=74727, A1*0.045,
IF(A1<=83526, A1*0.05,
IF(A1<=92906, A1*0.055,
IF(A1<=102866, A1*0.06,
IF(A1<=113406, A1*0.065,
IF(A1<=124525, A1*0.07,
A1*0.08)))))))))
Common Mistakes to Avoid
When using PAYG calculators or performing manual calculations, watch out for these common errors:
- Incorrect payment period: Using weekly rates for monthly payments or vice versa will give wrong results.
- Forgetting the tax-free threshold: Not claiming it when you should (or claiming it when you shouldn't) significantly affects your withholding.
- Ignoring HECS debts: If you have a study debt, your repayments will be automatically deducted once you earn over the threshold.
- Wrong super rate: The standard was 9.5% in 2018-2019, but some industry funds or enterprise agreements might have different rates.
- Not accounting for additional withholding: If you have multiple jobs, you might need extra tax withheld to avoid a bill at tax time.
- Using current year tables: Always make sure you're using the 2018-2019 tables, not more recent ones.
How PAYG Withholding Affects Your Tax Return
The amounts withheld through PAYG are credits against your final tax liability. At the end of the financial year:
- Your total income is calculated
- Your tax liability is determined based on the tax tables
- The PAYG amounts withheld are subtracted from your tax liability
- If you've paid more than you owe, you get a refund
- If you've paid less, you'll have a tax bill
Pro Tip: Adjust Your Withholding
If you consistently get large refunds, you might want to reduce your withholding by claiming the tax-free threshold on a second job or adjusting your additional withholding amount. Conversely, if you always owe money at tax time, consider increasing your withholding.
Historical Context: How 2018-2019 Compared to Other Years
The 2018-2019 financial year was notable for being the first year of the Low and Middle Income Tax Offset (LMITO), which provided tax relief of up to $530 for individuals. This was part of the government's Personal Income Tax Plan.
| Financial Year | Tax-Free Threshold | Top Marginal Rate | Super Guarantee | Key Changes |
|---|---|---|---|---|
| 2016-2017 | $18,200 | 45% ($180,001+) | 9.5% | No major changes to withholding schedules |
| 2017-2018 | $18,200 | 45% ($180,001+) | 9.5% | Introduction of the Medicare levy increase (later abandoned) |
| 2018-2019 | $18,200 | 45% ($180,001+) | 9.5% | Introduction of LMITO (up to $530 offset) |
| 2019-2020 | $18,200 | 45% ($180,001+) | 9.5% | LMITO increased to $1,080 |
Frequently Asked Questions
Q: Can I still use the 2018-2019 PAYG tables?
A: Yes, if you're preparing or amending a tax return for the 2018-2019 financial year. For current payments, you should use the most recent tables.
Q: How do I know if I claimed the tax-free threshold?
A: You would have indicated this on your Tax File Number Declaration form when you started your job. If you're unsure, check your payment summary or ask your employer.
Q: Why does my PAYG withholding seem too high/low?
A: Several factors could affect this:
- You might have claimed (or not claimed) the tax-free threshold incorrectly
- Your employer might be using the wrong tax tables
- You might have a HECS debt you didn't account for
- Your payment period might be set incorrectly in calculations
Q: Can I get my PAYG withholding back if it's too high?
A: You'll get it back as a refund when you lodge your tax return, but you can't get it back during the year unless you adjust your withholding amounts.
Q: How does PAYG withholding work for bonuses?
A: Bonuses and similar payments have special withholding rules. In 2018-2019, the ATO generally required withholding at a flat rate of 47% (including Medicare levy) for bonuses unless the "whole of amount" method was used.
Advanced: Manual PAYG Calculation Method
For those who want to understand the exact calculation process, here's how the ATO's withholding schedules work:
Step 1: Determine the withholding amount
Using the appropriate table based on payment period and tax-free threshold status.
Step 2: Calculate HECS/HELP repayment (if applicable)
Based on your repayment income and the thresholds for 2018-2019.
Step 3: Add any additional withholding
This is the extra amount you've requested to be withheld.
Step 4: Calculate superannuation
Multiply your gross payment by your super rate (standard was 9.5% in 2018-2019).
Step 5: Determine net payment
Subtract the withholding amount, HECS repayment, and superannuation from your gross payment.
For example, let's manually calculate for someone earning $75,000 annually with the tax-free threshold:
- Monthly gross: $75,000 / 12 = $6,250
- Withholding calculation:
- Excess over $3,760: $6,250 - $3,760 = $2,490
- Withholding: $945.90 + ($2,490 × 0.37) = $945.90 + $921.30 = $1,867.20
- Superannuation: $6,250 × 9.5% = $593.75
- Net payment: $6,250 - $1,867.20 - $593.75 = $3,789.05

- Late payment of withheld amounts
- Failure to provide payment summaries
- Incorrect reporting of withheld amounts
Case Study: Small Business PAYG Compliance
Let's look at how a small business with 5 employees would handle PAYG withholding in 2018-2019:
Business Profile:
- Café with 5 employees
- Weekly pay cycle
- Employees earn between $20,000 and $60,000 annually
- Two employees have HECS debts
Monthly Process:
- Calculate gross wages: Sum of all hours worked × hourly rates
- Determine withholding: Use weekly withholding tables for each employee
- Calculate HECS: For the two employees with debts, calculate repayment based on their yearly equivalent income
- Calculate super: 9.5% of ordinary time earnings for each employee
- Process payroll: Generate payslips showing gross, tax, super, and net amounts
- Report to ATO: Submit Single Touch Payroll report by the due date
- Pay withheld amounts: Transfer PAYG withholding to ATO by the 21st of the following month
Common Challenges:
- Variable hours: Casual employees with varying hours require recalculation each pay period
- Tax-free threshold: Ensuring new employees complete their TFN declaration correctly
- HECS debts: Employees don't always notify when they get a study debt
- Super guarantee: Calculating ordinary time earnings correctly for super purposes
Future of PAYG Withholding
While this guide focuses on 2018-2019, it's worth noting how PAYG withholding has evolved:
Recent Changes (Post-2019):
- 2019-2020: LMITO increased to $1,080
- 2020-2021: Introduction of "Stage 2" tax cuts (though legislated for 2022-23)
- 2021-2022: Super guarantee increased to 10%
- 2022-2023: Low and middle income tax offset (LMITO) increased again
- 2023-2024: Super guarantee increased to 11%
Upcoming Changes:
- Super guarantee: Scheduled to reach 12% by 2025
- Stage 3 tax cuts: Planned for 2024-25 (though subject to change)
- Single Touch Payroll: Expansion to include more detailed reporting
- Digital service providers: Increased integration with accounting software
Conclusion
The 2018-2019 PAYG withholding system, while complex, followed clear rules that can be accurately replicated with the right tools and understanding. Whether you're an employer ensuring compliance, an employee checking your payslip, or an accountant preparing historical returns, understanding these calculations is essential.
Our interactive calculator provides an accurate way to determine 2018-2019 PAYG withholding amounts, matching the ATO's official calculations. For Excel users, the provided formulas allow you to build your own calculators that will give identical results.
Remember that while PAYG withholding ensures you pay tax throughout the year, your final tax liability is determined when you lodge your tax return. The withheld amounts are credits against this liability, which is why you might get a refund or have an amount owing at tax time.
For the most accurate results, always:
- Use the correct financial year's tax tables
- Double-check your tax-free threshold status
- Include any HECS/HELP debts
- Consider additional withholding if you have multiple income sources
- Consult a tax professional if you're unsure about your situation
