Module C: Formula & Methodology
Our calculator uses the official ATO formulas for the 2016-2017 financial year. Here’s the detailed methodology:
1. Calculating Taxable Income
The basic formula for taxable income is:
Taxable Income = (Total Business Income - Total Business Expenses - Other Deductions) - Tax-Free Threshold (if applicable)
2. Tax Rates for Individuals (Sole Traders & Partners)
| Taxable Income | Tax Rate | Tax on This Portion |
|---|---|---|
| $0 – $18,200 | 0% | $0 |
| $18,201 – $37,000 | 19% | 19c for each $1 over $18,200 |
| $37,001 – $80,000 | 32.5% | $3,572 plus 32.5c for each $1 over $37,000 |
| $80,001 – $180,000 | 37% | $17,547 plus 37c for each $1 over $80,000 |
| $180,001 and over | 45% | $54,547 plus 45c for each $1 over $180,000 |
3. Company Tax Rate (2016-2017)
For small business companies (aggregated turnover less than $10 million), the tax rate was reduced to 28.5% (down from 30% in previous years). This was part of the government’s 2016-17 Budget measures to support small businesses.
4. Medicare Levy
The Medicare levy for 2016-2017 was 2% of taxable income for most taxpayers. The levy may be reduced or eliminated for low-income earners:
- Singles: No levy if income ≤ $21,335 (phased in up to $26,668)
- Families: No levy if income ≤ $36,001 (phased in up to $45,000)
- Seniors/Pensioners: Higher thresholds apply
5. Small Business Concessions
Key concessions available in 2016-2017 included:
- Instant Asset Write-Off: Increased to $20,000 (from $1,000) for assets purchased and installed ready for use by 30 June 2017
- Simplified Depreciation: Immediate deduction for assets costing less than $20,000
- Small Business Income Tax Offset: Up to $1,000 offset (8% of tax payable on business income)
- PAYG Installment Options: Ability to pay installments based on GDP-adjusted notional tax
Module D: Real-World Examples
Let’s examine three detailed case studies to illustrate how the calculator works in practice:
Case Study 1: Sole Trader with Moderate Income
Business: Freelance graphic designer (ABN registered)
Details:
- Total Income: $85,000
- Business Expenses: $22,000 (equipment, software, home office)
- Other Deductions: $3,000 (self-education)
- Tax Already Paid: $5,000 (PAYG installments)
- Structure: Sole Trader
Calculation:
Taxable Income = $85,000 - $22,000 - $3,000 = $60,000
Tax Payable:
- First $18,200: $0
- $18,201-$37,000: $3,572
- $37,001-$60,000: ($60,000 - $37,000) × 0.325 = $7,425
Total Tax: $3,572 + $7,425 = $10,997
Medicare Levy: $60,000 × 0.02 = $1,200
Small Business Offset: $10,997 × 0.08 = $879.76
Net Tax: ($10,997 + $1,200) - $879.76 - $5,000 = $6,317.24
Case Study 2: Partnership Business
Business: Café partnership (2 equal partners)
Details (per partner):
- Share of Partnership Income: $120,000
- Business Expenses: $45,000 (allocated share)
- Other Deductions: $5,000 (work-related)
- Tax Already Paid: $12,000
- Structure: Partnership
Key Considerations:
- Partners pay tax on their individual share of net partnership income
- Partnership itself doesn’t pay income tax
- Each partner’s circumstances affect their individual tax liability
Case Study 3: Small Business Company
Business: IT consulting company (Pty Ltd)
Details:
- Total Income: $450,000
- Business Expenses: $320,000
- Other Deductions: $15,000 (depreciation)
- Tax Already Paid: $25,000 (PAYG installments)
- Structure: Company (small business entity)
Calculation:
Taxable Income = $450,000 - $320,000 - $15,000 = $115,000
Company Tax = $115,000 × 0.285 = $32,775
Franking Credits = $32,775 / (1 - 0.3) = $46,821.43
Net Tax Position = $32,775 - $25,000 = $7,775 payable

Module G: Interactive FAQ
What were the key tax changes for small businesses in FY 2016-2017? +
The 2016-2017 financial year introduced several significant changes:
- Company tax rate reduction: Dropped from 30% to 28.5% for small business companies (turnover < $10m)
- Increased instant asset write-off: Threshold raised from $1,000 to $20,000 until 30 June 2017
- Expanded small business entity definition: Turnover threshold increased from $2m to $10m
- Increased small business income tax offset: Raised from 5% to 8% (max $1,000)
- Simplified BAS reporting: Optional quarterly GST reporting for small businesses
- PAYG installment changes: Option to pay based on GDP-adjusted notional tax
These changes were designed to improve cash flow and reduce compliance burdens for small businesses.
How does the calculator handle the small business income tax offset? +
The calculator automatically applies the small business income tax offset where eligible. Here’s how it works:
- Available to individuals (sole traders and partners) with business income
- Calculated as 8% of the income tax payable on your business income
- Maximum offset is $1,000 per year
- Offset is non-refundable (can only reduce tax to $0, not create a refund)
- You must be a small business entity (turnover < $10m)
The calculator applies this offset after calculating your basic tax liability but before accounting for any tax already paid.
What records do I need to keep for my 2016-2017 tax return? +
The ATO requires you to keep records for 5 years. Essential records include:
Income Records:
- Sales invoices and receipts
- Bank statements showing business income
- Cash register tapes
- Records of electronic payments (PayPal, credit card)
Expense Records:
- Receipts for all business purchases
- Bank and credit card statements
- Logbooks for vehicle expenses
- Home office expense calculations
- Asset purchase records (for depreciation)
Other Important Records:
- Business activity statements (BAS)
- PAYG payment summaries
- Superannuation contribution records
- Contractor payment records
- Stocktake records (if applicable)
For digital records, ensure they’re in a format that can’t be altered (like PDF) and that you have backups.
Can I claim home office expenses if I’m a sole trader? +
Yes, sole traders can claim home office expenses if they genuinely work from home. There are two main methods:
1. Simplified Method (45c per hour):
- Claim 45 cents for each hour you work from home
- Covers electricity, gas, cleaning, and furniture depreciation
- No need to keep specific receipts for these expenses
- Must keep a diary of hours worked from home
2. Actual Cost Method:
- Claim the actual additional costs incurred
- Can include:
- Electricity and gas (work-related portion)
- Phone and internet (work-related portion)
- Computer consumables and stationery
- Home office equipment depreciation
- Cleaning expenses
- Must keep receipts and calculate the work-related portion
- Need to maintain a home office diary for 4 weeks
You can also claim occupancy expenses (rent, mortgage interest, rates) if you have a dedicated work area, but this may affect your capital gains tax when you sell your home.
What’s the difference between tax deductions and tax offsets? +
This is an important distinction that affects how much tax you pay:
| Feature | Tax Deductions | Tax Offsets |
|---|---|---|
| What it does | Reduces your taxable income | Directly reduces your tax payable |
| Effect on tax | Indirect – lowers income that’s taxed | Direct – subtracts from tax owed |
| Value | Equal to your marginal tax rate × deduction amount | Equal to the offset amount (up to maximum) |
| Refundable | No | Some are, some aren’t |
| Examples | Business expenses, work-related purchases, depreciation | Small business income tax offset, low income tax offset, private health insurance rebate |
| Claim process | Subtract from income in tax return | Subtract from tax payable in tax return |
Example: If you’re in the 32.5% tax bracket:
- A $1,000 deduction saves you $325 in tax
- A $1,000 non-refundable offset saves you $1,000 in tax (but can’t create a refund)
How does the Medicare levy work for business owners? +
The Medicare levy is calculated as 2% of your taxable income, with some important considerations for business owners:
Key Points:
- Most taxpayers pay 2% of taxable income
- Low-income earners may pay a reduced levy or none at all
- The levy is in addition to your income tax
- Some business owners may qualify for exemptions
2016-2017 Thresholds:
| Category | No Levy Threshold | Phase-out Threshold |
|---|---|---|
| Singles | $21,335 | $26,668 |
| Families | $36,001 | $45,000 |
| Seniors/Pensioners (single) | $33,738 | $42,172 |
| Seniors/Pensioners (family) | $46,966 | $58,710 |
For Business Owners:
- If your business income fluctuates, you might move between levy thresholds
- The levy is calculated on your total taxable income (business + other income)
- If you have private hospital cover, you may qualify for a reduction or exemption
- The levy surcharge (additional 1-1.5%) applies to high-income earners without private cover
