Home Office Tax Deductions for Tradies: What You Can Claim When You Work

Most tradies don't think of themselves as home-based workers. But if you

use a part of your home regularly for business purposes -- quoting,

invoicing, scheduling, ordering materials, taking business calls,

storing tools or a work vehicle -- you may be entitled to claim home

office deductions and related expenses that many tradies miss entirely.

This guide explains what the ATO allows tradies to claim for home-based

business activity, the two calculation methods available, and what

documentation you need to support your claim.

When Can a Tradie Claim Home Office Deductions?

The ATO allows home office expense deductions when you have a dedicated

area of your home that is used regularly for carrying out income-earning

activities. For a sole trader tradie, this might be:

• A spare room or study used as a home office for business

administration

• A garage or shed used for storing tools, materials or equipment

• A covered area where you store or maintain your work vehicle

You can also claim additional running costs incurred because of business

activity conducted at home -- electricity, internet, phone -- even without

a dedicated room, though with a lower claim rate than a dedicated home

office.

The Two Claiming Methods

The ATO offers two methods for calculating home office deductions. From

1 July 2022, the rules changed significantly, and it's important to

understand which method applies and how.

Method 1: The Fixed Rate Method (67 cents per hour)

From 1 July 2022, the revised fixed rate is 67 cents per hour for each

hour you genuinely work from home on business activities. This rate

covers electricity and gas for home office use, phone and data costs

(for the portion related to work-from-home activity), computer

consumables and stationery, and the decline in value of your home office

furniture and equipment.

To use this method, you need to keep a record of the total hours you

worked from home during the year. The ATO accepts a diary or log, though

it can be a representative four-week sample rather than a full year if

your work pattern is consistent. You cannot use estimates.

Note that under the fixed rate method, you cannot claim separate

deductions for phone, internet or electricity -- those are already

included in the 67 cent rate. You can still claim the decline in value

of equipment separately.

Method 2: The Actual Cost Method

The actual cost method involves calculating the actual expenses incurred

as a result of working from home and claiming those directly. For a

dedicated home office, this includes a proportionate share of your rent

or mortgage interest (calculated on the floor area of the office as a

percentage of total home area), actual electricity costs for the room,

and the decline in value of office equipment and furniture.

The actual cost method can yield a higher deduction than the fixed rate

method if you have a large, dedicated office space with high running

costs. However, it requires more detailed record-keeping and involves a

more complex calculation. It also has CGT implications for homeowners --

if you claim a percentage of home ownership costs as a business

deduction, a corresponding portion of your home's future capital gain

may be assessable.

Most tradies who are homeowners are better served by the fixed rate

method to avoid CGT complications, but discuss this with your

accountant.

What Tradies Commonly Miss

Beyond the two primary home office calculation methods, there are

additional home-related deductions that many tradies overlook:

Home Office Equipment

If you use a computer, printer, phone or other equipment for business

purposes, the business-use portion is deductible. For equipment costing

under $300 and used more than 50% for business, you can claim the full

cost immediately. For equipment over $300, you claim depreciation over

the asset's effective life.

Mobile Phone

If you use your personal mobile phone for business calls, quoting,

emails and business apps, a portion of your bill is deductible based on

your business use percentage. Many tradies use their phone 60-80% for

business -- that's a meaningful deduction on a $100+ monthly phone bill.

Keep one month of phone records in a typical month to establish your

percentage.

Internet

Your internet service costs are deductible for the business-use portion.

If you use the internet for quoting, business email, scheduling,

research and ordering materials, a significant portion of your home

internet bill may be deductible. Again, keep a sample month of usage

records.

Tool and Equipment Storage

If you store tools or materials at home -- even in a garage or under a

carport -- you can claim a portion of the running costs of that storage

area as a business expense. This includes proportionate utility costs,

security systems, and any purpose-built storage shelving or systems.

The Documentation You Need

The ATO expects you to be able to substantiate home office claims. For

the fixed rate method, you need records of hours worked from home -- a

diary, calendar, or time-tracking app records are all acceptable. For

the actual cost method, you need receipts for all expenses being claimed

and floor plan measurements to calculate the area percentage.

Keep these records for five years from the date you lodge your return.

The ATO can audit up to five years in most cases, so shorter record

retention than that creates risk.

What You Cannot Claim

You cannot claim general household costs that you'd incur regardless of

any home business activity -- regular cleaning, garden maintenance, or

the full cost of utilities used predominantly for personal living. You

cannot claim rent if you own your home. You cannot claim mortgage

principal repayments (only interest, and only using the actual cost

method with the associated CGT implications).

And importantly: if your "home office" is a laptop on the kitchen table

used occasionally, the ATO expects proportionality in your claim.

Claiming a large home office deduction without a genuine, dedicated

business area is a known audit risk.

Practical Steps

If you conduct any business administration from home -- even just two or

three hours per week -- talk to your accountant about whether you're

claiming everything you're entitled to. Start logging your home-based

work hours now (there are simple phone apps that make this effortless)

and keep a copy of your utility bills.

For most tradies, home office deductions are a genuine and legal way to

reduce your tax bill by hundreds or potentially thousands of dollars per

year. With the right records, it's an easy and legitimate claim.
