Home Office Deduction Calculator

Calculate your home office tax deduction using the ATO fixed rate method (67¢/hour) or actual cost method. Get instant results with ATO-compliant calculations.

How to Use This Calculator

1. Choose Your Method

  • Fixed Rate: Simple option - claim 67 cents per hour worked from home
  • Actual Cost: Claim portion of actual expenses - usually gives higher deduction

2. Enter Your Work Hours

Provide your average hours per week worked from home and number of weeks worked. For most people, this is 52 weeks (full year).

3. Add Expenses (Actual Cost Method Only)

Enter your home office area, total home area, and annual expenses. The calculator will work out the deductible portion based on:

  • Floor area percentage for occupancy costs (rent, rates, insurance)
  • Floor area × time percentage for running costs (electricity, gas, etc.)
  • Floor area percentage for phone/internet (as a proxy for work use)

📝 Record Keeping Requirements

  • Keep a diary or timesheet showing when you worked from home
  • For actual costs: retain bills, receipts, and invoices as evidence
  • Records must show the work-related use of the expense

⚠️ What You Can't Claim

  • Coffee, tea, milk, and other general household items
  • Occupancy expenses if you use actual cost method (e.g., rent for employees)
  • Items already reimbursed by your employer
  • Capital expenses like purchasing furniture (but you can claim depreciation)

💡 Pro Tip: The actual cost method usually gives a higher deduction if you have significant home expenses. However, you must keep detailed records of all expenses and apportion them correctly.

Understanding Home Office Deductions in Australia

If you work from home, you may be able to claim a tax deduction for the costs you incur. The Australian Taxation Office (ATO) offers two methods to calculate your home office deduction: the fixed rate method and the actual cost method.

Fixed Rate Method (67 Cents Per Hour)

For the 2025-26 income year, the ATO's fixed rate method allows you to claim 67 cents per hour worked from home. This rate covers:

  • Electricity and gas for heating, cooling, and lighting
  • Decline in value of home office furniture and equipment
  • Repairs and maintenance of home office furniture and equipment
  • Phone and internet expenses

When to use: The fixed rate method is best if you don't have high home expenses or prefer a simple calculation. You only need to track your hours worked from home.

Actual Cost Method

The actual cost method allows you to claim the work-related portion of your actual running expenses. This usually results in a higher deduction if you have significant home expenses.

What You Can Claim:

  • Occupancy expenses (rent, mortgage interest, rates, insurance): Apportioned by floor area only
  • Running expenses (electricity, gas, repairs, cleaning): Apportioned by floor area and time used
  • Phone and internet: Apportioned by floor area as a proxy for work use
  • Depreciation: Decline in value of furniture and equipment, apportioned by floor area

Example: If your home office is 15m² out of a 150m² home (10%), and you work from home for 2,000 hours per year (approximately 23% of the year), you would claim:

  • 10% of occupancy expenses (rent, rates, insurance)
  • 2.3% of running expenses (10% × 23% = 2.3%)
  • 10% of phone/internet costs

Record Keeping

To claim home office deductions, you must keep proper records:

  • A diary or timesheet showing the hours you worked from home
  • Receipts and bills for expenses (if using actual cost method)
  • Evidence that the expense was for work-related purposes
  • Records of the floor area of your home office and total home area (if using actual cost method)

What You Cannot Claim

  • Coffee, tea, milk, and other general household items (even if consumed while working)
  • Occupancy expenses like mortgage payments or rent if you're an employee (except mortgage interest using actual cost method)
  • Items already reimbursed by your employer
  • Capital expenses for purchasing furniture (but you can claim depreciation over time)
  • Costs of initial setup or renovations to create a home office

Who Can Claim Home Office Deductions?

Home office deductions are available to a wide range of workers:

  • Employees who work from home (whether occasionally or full-time)
  • Contractors and consultants operating from home
  • Self-employed individuals and sole traders
  • Small business owners running their business from home

Important: You cannot claim a deduction if your employer has already reimbursed you for the expense, or if you're simply taking a lunch break at home between attending work at different locations.

Choosing the Right Method

MethodBest ForRecord Keeping
Fixed Rate (67¢/hr)Simple situations, occasional WFH, low home expensesJust track hours worked from home
Actual CostHigh home expenses, dedicated home office, full-time WFHKeep all receipts, bills, and records of floor area

You can switch between methods from year to year, but you must use only one method for each income year. Calculate your deduction using both methods to see which one gives you the best result.

Frequently Asked Questions

Can I claim home office expenses if I only work from home occasionally?

Yes, you can claim for any hours you work from home, even if it's just one day per week. You must keep a record of all hours worked from home and the expenses must be genuinely work-related.

Do I need a dedicated home office room to claim the deduction?

No, you don't need a separate room. You can claim for working from any area of your home, such as the dining table or living room. However, a dedicated office space may make it easier to calculate floor area percentages for the actual cost method.

Can I claim the full cost of my internet plan?

No, you can only claim the work-related portion. If using the fixed rate method, internet is already included in the 67 cents per hour. If using the actual cost method, you need to apportion your internet costs based on the floor area percentage as a proxy for work use.

What if my employer provides me with a laptop or phone?

You can still claim home office running expenses like electricity, heating, and internet. However, you cannot claim for the laptop or phone itself since your employer provided it. You also cannot claim for expenses your employer has already reimbursed.

Can I use the shortcut method (80 cents per hour)?

The shortcut method was a temporary measure introduced during COVID-19 and ended on 30 June 2022. From 1 July 2022 onwards, you must use either the fixed rate method (52 cents for 2022-23, 67 cents for 2023-24 onwards) or the actual cost method.

How long do I need to keep my records?

You must keep your records for five years from the date you lodge your tax return. This includes timesheets showing hours worked from home and receipts for expenses claimed using the actual cost method.

Can I claim if I'm self-employed or run my own business?

Yes, self-employed individuals, contractors, and business owners can claim home office expenses. The same calculation methods apply, but you may have additional flexibility in how you structure your claims. Consult with a tax professional for advice specific to your business structure.
