Formula Used
Assessable employment income = employment income + self-employment income − Work Bonus used.
Personal assessable income = assessable employment income + investment income + rental income + business income + other income.
Combined assessable income = personal assessable income + partner assessable income.
Single taper reduction = max(0, tested income − free area) × taper rate.
Two-tier reduction = first excess × first taper + second excess × second taper.
Estimated payment = max(0, maximum payment − total reduction).
Cut-off rule = if tested income reaches the cut-off, estimated payment becomes zero.

Centrelink Income Testing Overview
Centrelink income testing compares assessable income with an income free area. A free area is the amount that may be earned before a payment starts reducing. After that point, a taper rate reduces the fortnightly payment. Different payments use different thresholds. Some payments also use partner income rules. This calculator turns those rules into a clear worksheet.
Why This Calculator Helps
Many people receive income from more than one place. Wages, self-employment, investments, rent, and business activity can all affect the result. The tool separates each source. It then totals assessable personal income and partner income. This helps users check which source causes the largest reduction. It also shows the remaining payment after the income test.
Flexible Statistical Design
The calculator uses editable parameters. You can set the payment amount, free area, taper rates, second threshold, partner threshold, and cut-off point. This is useful because public rates may change. It also helps compare scenarios. For example, a user can model extra hours, a higher partner wage, or a different Work Bonus amount.
Work Bonus and Adjustments
A Work Bonus can reduce assessable employment income for eligible pensioners. The calculator applies the bonus before the taper. Child additions can also be entered where a rule allows them. These adjustments are shown separately, so the final reduction is easy to audit. The summary also reports effective withdrawal rate. That rate compares reduction with total assessable income. It is not a tax rate, but it helps explain pressure on the budget.
Interpreting the Output
The result is an estimate. It does not decide eligibility. Centrelink also uses assets tests, residence rules, reporting rules, and special income rules. Some income is assessed as gross income. Some business or rental income may be assessed as net income. Always compare the worksheet with official guidance before making financial decisions.
Good Planning Practice
Run several examples before accepting extra work or changing investments. Save the CSV for spreadsheets. Save the PDF for records. Keep the rates updated when Services Australia updates them. Review one fortnight at a time. Enter income when paid, not when earned, if reporting rules require that approach. Check all settings after each official rate update. Keep notes beside calculations.
FAQs
Is this an official Centrelink calculator?
No. It is an estimate tool. Use it for planning only. Always check your final entitlement through Services Australia or your Centrelink online account.
Why are thresholds editable?
Centrelink rates and limits can change. Different payments also use different rules. Editable inputs let you update the calculator without rewriting the page.
Should I enter gross or net income?
Employment income is generally entered as gross income. Some business or rental amounts may be assessed differently. Check the rule for your payment before relying on the result.
What does taper rate mean?
A taper rate is the reduction applied to income over a threshold. A 0.50 taper means payment falls by 50 cents for each extra dollar.
What is the Work Bonus offset?
It is an amount that may reduce assessable work income for eligible pensioners. This calculator applies it before calculating income-test reduction.
Does this include the assets test?
No. It focuses on income testing. Some payments also use assets, residence, compensation, and eligibility rules.
Why does partner income matter?
Many Centrelink payments assess partner income. Some rules assess combined income. Others apply a separate partner taper after a partner threshold.
