# Small Business Income Tax Offset ATO ($1,000 SBITO) & Non-Commercial Loss Rules for Sole Traders (2026–27)

**Short answer: Under the small business income tax offset ATO rules, Australian sole traders, freelancers, consultants, and tradies with aggregated annual turnover under $5 million receive an automatic 8% tax discount on their net small business income, capped at $1,000 per income year on their myTax assessment. Conversely, if your sole trader business makes a net tax loss at Item P8, Division 35 non-commercial loss rules only allow you to offset that loss against your PAYG salary if your adjusted income is under $250,000 and you pass at least one of four statutory tests.**

## How Does the Small Business Income Tax Offset ATO ($1,000 Cap) Work in 2026–27?

According to official [ATO Small Business Income Tax Offset guidance](https://www.ato.gov.au/businesses-and-organisations/income-deductions-offsets-and-records/tax-offsets/small-business-income-tax-offset), the **Small Business Income Tax Offset (SBITO)**—also called the unincorporated small business tax discount—reduces the personal income tax you pay on net business income earned as a sole trader (or from a partnership/trust share of net small business income).

You do not need to file a separate application form: the ATO calculates the offset automatically from the **Net Small Business Income** you report at **Item P8 (Business income and expenses)** of your myTax individual tax return:

$$\text{SBITO} = \min\!\left(\$1,000,\; \text{Basic Income Tax Liability} \times \frac{\text{Net Small Business Income}}{\text{Total Taxable Income}} \times 8\%\right)$$

| Net Sole Trader Profit (Item P8) | Other PAYG Salary Income | Total Taxable Income (AUD) | Proportion of Income From Sole Trader Business | Approximate 8% SBITO Discount (Capped at $1,000) |
| :--- | :--- | :--- | :--- | :--- |
| **`$35,000`** | `$0` | `$35,000` | `100%` | **`~$215`** |
| **`$75,000`** | `$0` | `$75,000` | `100%` | **`$1,000` (Max Cap Reached)** |
| **`$45,000` (Side Business)** | `$90,000` | `$135,000` | `33.3%` | **`~$840`** |
| **`$110,000`** | `$0` | `$110,000` | `100%` | **`$1,000` (Max Cap Reached)** |

### Important SBITO Exclusions (`PSI` Trap)
If your consulting, design, IT, or contracting income is classified as **Personal Services Income (PSI)** and you **do not pass the Results Test** (meaning the PSI rules apply to you at Item P1), that income is excluded from the **small business income tax offset ATO** calculation. See our **[ATO Personal Services Income (PSI) & Results Test Guide](/keel/australia-ato-personal-services-income-psi-sole-trader-guide/)** and **[Australia Sole Trader Tax Return Guide](/keel/australia-sole-trader-tax-return/)** to ensure your contract structure qualifies as a Personal Services Business (PSB).

## How Do the 4 Division 35 Commerciality Tests Work in Detail at Item P9?

When your sole trader business incurs a net loss in its first year—for example, after claiming the `$20,000` instant asset write-off on tools, camera gear, or a commercial ute—passing any one of the four Division 35 tests at **Item P9** lets you deduct that loss immediately against your PAYG salary:

## When Can a Sole Trader Offset a Business Loss Against PAYG Salary (Division 35 Non-Commercial Losses)?

Many Australians launch a freelance design studio, consulting practice, photography business, or trade business while still working a part-time or full-time PAYG job. If your deductible business expenses (such as camera gear, tools, vehicle logbook claims, or software) exceed your ABN invoiced revenue in Year 1, you have a **net business loss at Item P8**.

Under [ATO Non-Commercial Losses rules (Division 35 ITAA 1997)](https://www.ato.gov.au/businesses-and-organisations/income-deductions-offsets-and-records/losses/non-commercial-losses), you cannot automatically subtract a side-business loss from your PAYG wages unless you clear **two gates** at **Item P9 (Business loss activity details)**:

### Gate 1: The $250,000 Income Requirement
Your adjusted non-business income (taxable income + reportable fringe benefits + reportable super contributions + total net investment losses, ignoring the business loss) must be **less than `$250,000`**. If you earn `$250,000` or more, the loss is quarantined and carried forward to offset future profits from that same business activity.

### Gate 2: Pass at Least 1 of the 4 Statutory Commerciality Tests (or Arts Exception)

| Statutory Test (Item P9) | Exact ATO Threshold to Pass | Who Usually Uses This Test |
| :--- | :--- | :--- |
| **1. The $20,000 Assessable Income Test** | Your gross ABN business turnover (before expenses, excluding GST) is **at least `$20,000`** in the income year (or would reasonably be $\ge \$20,000$ over a full 12-month year if you started mid-year) | First-year tradies, consultants, real estate agents & freelancers who bought heavy gear/utes |
| **2. The Profits Test** | Your business activity has produced a net tax profit in **at least 3 of the past 5 income years** (including the current year) | Established sole traders experiencing a temporary downturn or heavy asset write-off year |
| **3. The Real Property Test** | Real property (land/buildings, excluding your private home) of **at least `$500,000`** is used on a continuing basis in the business | Commercial workshop owners or primary producers |
| **4. The Other Assets Test** | Depreciating assets, leased equipment, or trading stock worth **at least `$100,000`** are used continuously in the business (excluding passenger cars) | Excavators, commercial printing/production studios & heavy contractors |
| **Special Exception: Professional Arts Business** | Your assessable income from non-business sources (e.g., PAYG salary) is **less than `$40,000`** and you run a professional arts business (author, photographer, filmmaker, designer, performing artist) | Creative freelancers, photographers & videographers |

## Why Does Tracking Every ABN Invoice and Docket in Keel Protect Both Your $1,000 SBITO and Item P9 Loss Claim?

1. **Proving the `$20,000` Assessable Income Test:** If your first-year ABN turnover is `$19,400`, your `$8,000` business loss is deferred to next year; if you issue and record a valid `$800` invoice before 30 June (or prove a pro-rata `$20,000` run-rate from your start date), you pass the `$20,000` test and unlock an immediate PAYG tax refund.
2. **Separating Private vs Business Use for 5 Years:** Both SBITO and Item P9 claims require clean 5-year ATO records separating business invoices, Bunnings/supplier thermal dockets, and `88c/91c per km` or 12-week car logbooks.

## Frequently asked questions

**How do I claim the small business income tax offset on my Australian tax return?**
You do not enter a separate claim amount for the **small business income tax offset ATO** discount. Simply enter your sole trader gross income and allowable deductions accurately at **Item P8 (Business income and expenses)** in myTax (specifically in the **Net small business income** box), and the ATO automatically calculates and applies up to `$1,000` (at the `8%` offset rate) on your Notice of Assessment.

**What happens to my sole trader business loss if I do not pass the 4 non-commercial loss tests?**
Your business loss is **not lost forever**—it is **deferred (quarantined)** at Item P8/P9 and carried forward indefinitely. In the next income year that your sole trader business generates a net profit (or the year you pass the `$20,000` Assessable Income Test while under the `$250,000` income cap), you subtract the deferred loss to reduce your taxable profit.

**If I start my sole trader business in April and only bill $6,000 by 30 June, can I still pass the $20,000 Assessable Income Test?**
Yes! Under ATO Non-Commercial Loss rules, if you commenced business part-way through the financial year, you can pass the Assessable Income Test if you can make a **reasonable estimate** (backed by your signed quotes, monthly invoice run-rate, and client pipeline in **Keel**) showing that your business would have earned at least `$20,000` had it operated for the full 12 months.

**Does the $1,000 Small Business Income Tax Offset create a cash refund if my total tax bill is $0?**
No. The SBITO is a **non-refundable tax offset** under Australian tax law. It can reduce your personal income tax liability all the way down to `$0` (which can increase the refund of any PAYG tax withheld from a day-job salary or quarterly PAYG instalments), but any unused portion of the `$1,000` cap cannot be paid out as a negative-tax cash credit or carried forward to future income years.

**Can I track my ABN invoices, GST, and Item P8 expenses on my iPhone without paying for Xero or MYOB?**
Yes. **[Keel](https://apps.apple.com/us/app/keel-invoice-maker-receipts/id6786659713?ppid=8470921a-830e-47a3-abf5-bf0b1cce24ac)** is built specifically for Australian sole traders, freelancers, consultants, real estate agents, and tradies who want unlimited free daily quotes, ATO-compliant ABN Tax Invoices, 100% on-device Bunnings and supplier receipt OCR, and `88c/91c` per kilometre logbooks on their iPhone with zero bank connection and no monthly subscription.
