Working from home offers flexibility and convenience, but it also comes with financial benefits in the form of tax deductions. If you use a portion of your home exclusively for business purposes, you may be able to claim home office expenses, reducing your taxable income and improving your cash flow.
This guide outlines the key deductions available, how to calculate them, and best practices to ensure compliance with tax regulations.
Understanding Home Office Deduction Eligibility
To claim home office deductions, your workspace must meet specific requirements:
- Exclusive Business Use – The area must be used solely for business activities and not for personal purposes.
- Primary Place of Business – Your home office should be where you conduct most of your work, including administrative tasks, client meetings, or business operations.
If you meet these criteria, you may be eligible to claim a range of expenses related to maintaining and operating your home office.
Deductible Home Office Expenses
There are two types of home office expenses: direct and indirect.
Direct Expenses (Fully Deductible)
These costs relate specifically to your home office and are 100% deductible:
- Office furniture (desk, chair, shelving units)
- Office equipment (computer, printer, monitors, business phone)
- Business-related repairs and maintenance within the office space
- Office supplies (paper, ink, stationery, postage)
Indirect Expenses (Partially Deductible)
These are general home expenses shared between personal and business use. The deductible portion depends on the percentage of your home used for business. Common indirect expenses include:
- Rent (if renting a property)
- Mortgage interest (for homeowners)
- Utilities (electricity, heating, water)
- Internet and phone costs (business portion only)
- Home insurance
- Property rates (council rates)
- Depreciation on home office assets
To determine the deductible amount, calculate the proportion of your home dedicated to business activities. This is typically measured by comparing the square meterage of your office to your total home area.
Claiming Home Office Deductions in New Zealand and Australia
Each country has specific methods for claiming home office deductions.
New Zealand (IRD Guidelines)
The Inland Revenue Department (IRD) allows two primary methods:
- Square Meter Rate Method – This is a simplified approach where you claim a set rate per square meter of your home office, covering utilities and other costs.
- Actual Cost Method – You calculate the exact portion of home expenses related to business use and claim accordingly.
Australia (ATO Guidelines)
The Australian Taxation Office (ATO) provides two methods:
- Fixed Rate Method – A set rate per hour for running expenses such as electricity, internet, and phone usage. This method is straightforward and requires minimal record-keeping.
- Actual Cost Method – Requires detailed record-keeping to calculate and claim the exact proportion of business-related home expenses.
Best Practices for Maximising Your Deductions
To ensure compliance and optimise your tax savings, follow these best practices:
- Keep Accurate Records – Maintain receipts, invoices, and records of all home office expenses. Digital tools can help track these efficiently.
- Track Business Use Percentage – Measure the office space in relation to your home’s total area to accurately calculate deductions.
- Avoid Over-Claiming – Only claim expenses directly related to business activities to prevent tax audits or penalties.
Home office deductions can significantly reduce your taxable income, but it is crucial to follow tax regulations and keep proper records. By understanding what expenses are deductible and choosing the most suitable method for claiming, business owners and remote workers can maximise their tax benefits while remaining compliant.
