Tax Deductions Limits

The way we work is changing, and for many people working from home is the new normal. Deductions working at home allows for a huge amount of flexibility plus there are numerous ways to deduct home office costs in your tax return.

Many people don't know they are able to claim Deductions Working at home and often miss out on valid deductions. But it's important to make sure you stay within the rules to avoid being penalised for making a mistake.

The most common errors are: claiming too high a work-related proportion for a particular type of expense, claiming something that shouldn't be claimed at all or simply not keeping records to substantiate the expense.

If you work from home (either part-time or full time) then some portion of the home office expenses may be claimed as a tax deduction. Deductions working at home, if you set up your home office in a room that is shared or has a dual purpose (such as a living or dining room), you can only claim the expenses for the hours you had exclusive use of the area.

What are the rules for Deductions Working at home?

If your home is your place of work and you have an area set aside exclusively for work activities, you may be able to claim both occupancy and running expenses. If you carry on your work or business elsewhere (such as an office) but do some work at home occasionally, you cannot claim occupancy expenses even if you have a home office area set aside.

Home office expenses you might be able to claim include:

  • Occupancy expenses Such as rent, mortgage interest, rates, land taxes and house insurance premiums (but only in limited circumstances).
  • Heating, cooling and lighting You have to heat your home office in the winter and keep it cool during the summer. You also need light to see what you're doing! That means that you can claim a proportion of the various household utility bills that relate to the time you spend working in your home office. You can't claim for periods where the home office space is being used for other purposes and nor can you claim for the element of your bills that relates to the rest of your home.
  • Home office equipment, including computers, printers and telephones You can claim the full cost (for items costing up to $300) or the decline in value (for items costing $300 or more). If you're self-employed, you may be able to immediately write-off equipment costing up to $20,000.
  • Work-related phone calls (including mobiles) and phone rental You can claim a portion reflecting the share of work-related use of the line if you can show you are on call, or have to phone your staff, employer, customers or clients regularly while you are away from your workplace.
  • Depreciation of home office furniture and fittings If you kit out your home office with furniture such as desks, shelving and cupboards, you can claim a deduction for the decline in value of that furniture to the extent that it relates to your work activity. That's likely to lead to a write-off of the cost over a period of several years (the "effective life" of the asset).
  • Depreciation of office equipment and computers Similarly if you purchase items of technology for use in your home office, you can depreciate them over their life and claim a deduction each year for the work-related element. That might include:
    • Computers
    • Laptops
    • Tablets
    • Mobile phones
    • Printers
  • Other items Make sure you claim for the work-related proportion of other costs such as:
  • Computer consumables (like printer ink)
  • Stationery
  • Telephone and internet costs
  • Cleaning costs
  • Costs of repairs to your home office furniture and fittings

Receipts or other written records/evidence

In making home office deductions, ensure that you can substantiate all expenditure claims through receipts of diaries. This includes:

  • Receipts for items of equipment you have purchased
  • Diary entries you make to record your small expenses ($10 or less) totaling no more than $200, or expenses you cannot get any kind of evidence for, regardless of monetary amount.
  • Diary indicating your running expenses related to working in your home office. Here, you need to detail the time you spend in the home office compared with other users. Keep a diary record for a minimum 4 week representative period. This can also include calculations of how much you used your equipment.
  • Itemised phone accounts from which you can identify work-related calls.

Australian Tax Office rate per hour

As an alternative to keeping such records, you can use a fixed rate of 52 cents per hour for each hour that you work from home to allow for home office expenses. Under this method, you can also include the decline in the value of office equipment (such as computers and faxes) but not furniture. In this case, you are unable to make additional claims for individual items.

The following costs are not deductible as part of home office expenses:

  • Mortgage or interest costs
  • Rates and taxes
  • Depreciation on the home.

The ATO has implemented a shortcut method to cover the period from 1  March to 30  June 2020. During this time you claim a deduction for $0.80 per hour of documented work, and this covers all deductible running expenses. But note that, if you use this method, you cannot claim any other expenses for working from home for that period.

Method 2: Rate per hour
