Self-Employed Age Pension Reporting Guide: Centrelink MOD F, Profit and Loss (SU580) & Work Bonus

While the Australian Government actively encourages older Australians to work by offering the permanent $11,800 Work Bonus, reporting business income to Services Australia (Centrelink) is vastly different from reporting standard employee wages.

Because sole trader earnings are not tracked by the ATO's Single Touch Payroll (STP) system, Centrelink cannot automatically monitor your net trading profit. To calculate your pension payments accurately—and prevent your pension from being wrongfully reduced—Services Australia requires you to complete two distinct, complementary forms:

1. Form MOD F (Business details form - MOD F): The master Business Details form that establishes your business identity, trading structure, commencement dates, ownership share, work duties, and capital background.
2. Form SU580 (Profit and Loss Statement - SU580): The operational Statement of Income and Expenses that calculates your net cash profit after allowable operating expenses.

This guide outlines your statutory reporting obligations, how the Work Bonus applies to sole traders, the common pitfalls to avoid, and how to maintain compliance without high accounting fees.

1. How Centrelink Assesses Self-Employed Pensioners

When you receive the Age Pension, Services Australia applies both an Income Test and an Assets Test under the Social Security Act 1991. Your pension entitlement is determined by whichever test produces the lower payment amount.

                      Self-Employed Pensioner                                  │          ┌───────────────────────┴───────────────────────┐          ▼                                               ▼ BUSINESS DETAILS & ASSETS                         INCOME TEST Assessed via Form MOD F                     Assessed via Form SU580 • Master Business Details & Structure       • Statement of Income and Expenses • Duties & Hours Worked (Q23)               • Net Cash Trading Profit • Income Variation Justification (Q16)      • GST-Exclusive Cash Rules • Asset & Liability Schedule (Q14)          • Strict Depreciation Exclusions 

• Form MOD F (Business Details): Captures the qualitative and structural nature of your business. It verifies that your business is an active enterprise, records your operational hours and duties, documents changes in your earning capacity, and records the net value of business assets (tools, vehicles, stock, and bank balances) less business debts.
• Form SU580 (Statement of Income and Expenses): Evaluates your ongoing net cash profit (gross trading revenue minus allowable operating expenses) to establish the assessable income rate applied to your pension.

⚠️ Critical Warning on Fortnightly myGov Reporting: If you work as a sole trader or contractor, never enter your gross business turnover into the fortnightly myGov employment wage screen. That screen is strictly for PAYG employee wages. Entering business revenue there causes Centrelink to treat gross sales as 100% personal income without deducting your legitimate operating expenses, resulting in an immediate and unnecessary reduction in your pension. Self-employment income must be assessed through Form MOD F and Form SU580.

2. Unlocking the $11,800 Work Bonus for Sole Traders

The Work Bonus (Social Security Guide 3.1.15.20) is one of the most valuable concessions available to working pensioners, yet many sole traders fail to receive it due to incomplete paperwork:

• The Fortnightly Concession: The first $300 per fortnight ($7,800 per year) of work income is 100% exempt from the pension income test.
• The Income Bank: Any unused portion of the $300 concession accumulates automatically in your Work Bonus Income Bank, up to a permanent cap of $11,800.
• Smoothing Seasonal Earnings: If you have $11,800 banked and take on a seasonal $10,000 contracting job or consulting project, you can earn that entire $10,000 without losing a single dollar of your Age Pension.

3. The "Gainful Work" Rule (Why Question 23 on Form MOD F Is Critical)

Under Social Security Guide 3.1.15.40, the Work Bonus applies to self-employment income only if it is derived from "gainful work" involving your personal effort, skills, or active labour.

• Eligible Activities: Consulting, trade maintenance, gardening, bookkeeping, rideshare driving, tutoring, bespoke manufacturing, or active retail.
• Ineligible Activities: Passive investments, rental properties, dividends, or enterprises where you are merely a silent financial investor.

How to Secure Your Exemption: In Question 23 of Form MOD F, explicitly detail the physical, administrative, and operational duties you personally perform and the hours you work each week. If Question 23 is left blank, Centrelink may classify your business as "passive investment income," which does not qualify for the $300/fortnight Work Bonus exemption.

4. Form MOD F (Business Details): When Pensioners Must Submit It

Form MOD F is the master schedule Services Australia uses to evaluate any sole proprietorship or partnership. Self-employed pensioners must submit Form MOD F in four primary scenarios:

1. Claiming the Age Pension with an Active ABN: If you or your partner hold an active sole-trader ABN when turning 67, Centrelink will require a MOD F to assess the business structure and trading background.
2. Starting a Micro-Business While on Payment: Registering an ABN or launching a sole-trader venture to utilise your Work Bonus automatically triggers a MOD F requirement.
3. Transitioning into Retirement (Scaling Down Work): If you ran a full-time business earning $80,000 last financial year, but upon turning 67 you scale down to 10 hours a week earning $12,000, Centrelink will default to assessing your previous year's ATO Tax Return—unless you notify them of the change.
   • The Solution: Tick "Yes" at Question 16 on Form MOD F ("Is your current income from the business different to that shown on the latest Profit and Loss Statement or Income Tax Returns?"). Attach a current 13-week SU580 Profit & Loss Statement reflecting your lower retirement earnings so Centrelink assesses your actual reduced run-rate.
4. Closing or Pausing a Business (Questions 20–22): When you retire fully and cease trading, you must lodge Form MOD F (Questions 20–22) to certify business cessation so Centrelink removes historical notional income from your record.

5. Form SU580 (Statement of Income and Expenses): Declaring Net Profit

While Form MOD F captures your overall business structure and assets, Form SU580 captures your operational figures. Centrelink typically requires an SU580 covering 13 weeks (90/91 days) or 26 weeks (182 days) to establish an annualised net profit run-rate.

Essential Rules for Completing an SU580

• Exclusive of GST: If registered for GST, all revenue and expense figures must be entered net of GST. Centrelink does not treat collected GST or refunded input tax credits as business income or expenses.
• Disallowed Personal Drawings: Transfers from your business account to your personal account are owner drawings (personal living funds), not deductible business expenses.
• No Personal Superannuation Deductions: Superannuation contributions you make for yourself cannot be deducted on an SU580 (Social Security Guide 4.7.1.30), even if tax-deductible on your personal income tax return.
• Logbook Apportionment for Vehicles: If using a private vehicle for business tasks, running costs (fuel, servicing, registration, and insurance) can only be claimed on the SU580 in direct proportion to your verified business logbook percentage.

5. The Depreciation & Capital Purchases Trap on Form SU580

The most frequent reporting error made by self-employed pensioners involves the purchase of work equipment, commercial vehicles, and machinery.

Under Section 1075 of the Social Security Act 1991, Centrelink evaluates capital expenditures under rules that differ fundamentally from the ATO:

Submitting a standard accounting P&L that includes an Instant Asset Write-Off or capital equipment purchase will cause Centrelink to reject the deduction, recalculate your income upwards, and potentially raise an overpayment debt.

6. What About DVA Service Pensioners? (Form D0525)

If you are an Australian Defence Force veteran or partner receiving a means-tested payment from the Department of Veterans' Affairs (DVA)—such as the Service Pension or Income Support Supplement (ISS)—the reporting framework is aligned:

• The DVA Work Bonus: Eligible DVA service pensioners receive the identical $300 per fortnight ($11,800 banked) Work Bonus concession for active self-employment.
• The Business Details Form: DVA uses Form D0525 (Business Details — Partnerships and Sole Traders), which mirrors Centrelink’s Form MOD F field-for-field.
• Profit and Loss Verification: DVA accepts the official Centrelink SU580 form or an All Sorted Profit & Loss Statement to verify net trading income under the Veterans' Entitlements Act 1986.

7. Compliance Checklist for Self-Employed Pensioners

Before uploading your paperwork to myGov or mailing it to Services Australia, verify each item:

• [ ] Are all figures GST-exclusive? Ensure GST has been removed from all revenue and expense categories if registered.

• [ ] Is Form MOD F identified correctly? Form MOD F is your master Business Details form establishing structure, trading history, and asset values—not a standalone assets test.
• [ ] Have you completed Question 16 on Form MOD F? If your current retirement earnings are lower than your last tax return, ensure you tick Yes to avoid being assessed on past full-time income.
• [ ] Is Question 23 completed on Form MOD F? Itemise your personal tasks and hours to secure your $300/fortnight ($11,800 max) Work Bonus exemption.
• [ ] Have you excluded tax depreciation and capital purchases? Verify that no Subdivision 328-D write-offs or asset purchases are included as operating expenses on your SU580.
• [ ] Are both forms lodged together? Always lodge Form MOD F and your current SU580 Profit & Loss Statement simultaneously.
