How Tax Deductions Work
Tax deductions reduce your taxable income, which in turn reduces your tax liability. The key is understanding what expenses are deductible and maintaining proper records.
Types of Deductions
| Deduction Type | Examples | Requirements | Record Keeping |
|---|---|---|---|
| Investment-Related | Interest, fees, advice | Income-producing purpose | Receipts required |
| Work-Related | Travel, equipment, training | Work-related purpose | Diary or receipts |
| Business | Operating expenses | Business purpose | Business records |
| Charitable | Donations to DGRs | DGR status | Receipts required |
The Theory Behind Tax Deductions
Tax deductions work through several key principles:
- Income Reduction: Deductions reduce your taxable income
- Tax Rate Application: Tax savings equal deduction × marginal tax rate
- Purpose Test: Expenses must be incurred for income-producing or work-related purposes
- Documentation: Proper records must be maintained
- Timing: Deductions are claimed in the year the expense is incurred
The key insight is that every dollar of legitimate deductions saves you tax at your marginal rate, making deduction maximisation a valuable strategy.
