Tax Breaks for Working from Home: 2026 Small Business Guide

Could the room you work in, the power it uses and the equipment on your desk affect your tax position in different ways? For Australian small-business owners, tax breaks for working from home aren’t a single catch-all claim. The right treatment depends on the business purpose, any private use and your business structure. It’s understandable to feel unsure, especially when a claim needs clear supporting records.

This guide explains which home-working costs may be deductible, what evidence to organise and how different calculation methods can affect your tax and cash flow. It also separates running expenses from other home costs, so you can assess which approach may suit your circumstances.

We explain the topic from a CPA perspective, distinct from a Chartered Accountant viewpoint, and focus on practical considerations for small-business owners. Careful record-keeping and a clear understanding of your circumstances can help you make informed tax decisions and support the lifestyle you’re working towards.

What work-from-home tax breaks can small-business owners consider?

Start by identifying which home-working costs relate to your business. A work-from-home tax deduction is a claim for an expense that meets the relevant tax rules and has a genuine connection to earning business income. The treatment depends on the type of expense, your business structure and the circumstances behind the claim. Ordinary household spending doesn’t become deductible simply because you also work at home.

Small businesses operating from home are often described as Small office/home office (SOHO) businesses. The term describes a way of working, not automatic eligibility for a tax deduction. Focus on the business use of each expense and the current Australian Taxation Office (ATO) rules.

Which work-from-home expense categories may be relevant?

Potential claims generally fall into a few categories. Each has different considerations:

• Running expenses: Costs such as electricity, gas, phone and internet may be relevant to the extent they relate to business use. For the 2025-26 income year, the ATO fixed-rate method is 70 cents per hour worked from home. It covers specified running costs, so those costs can’t also be claimed separately under that method.
• Equipment and work-related items: A desk, computer or other item may be treated differently from a recurring household bill. Business use, private use and applicable deduction or depreciation rules all matter. The fixed rate doesn’t include the decline in value of capital assets, which may be considered separately under the applicable rules.
• Occupancy expenses: Rent, mortgage interest and council rates are separate from running expenses. A dedicated business area used exclusively for business may affect whether these costs can be considered, but eligibility and potential consequences depend on the circumstances.

An alternative to the fixed-rate method is the actual-cost method, which considers the work-related portion of eligible running expenses. The better fit depends on your records and circumstances, not just which calculation appears more favourable.

Why does business purpose matter for a home-office claim?

Business-purpose use means using an expense or household resource to carry out business activities, rather than for personal or family purposes. A home internet connection, for example, may be used for both work and private activities. In that case, an appropriate apportionment should reflect business use and be supported by evidence. Keep your method clear and consistent. Paying an expense from a business account doesn’t make its private portion deductible.

From a CPA perspective, assess the purpose, records and business arrangement together. CPA and Chartered Accountant are distinct professional designations. Careful classification can support sound tax planning and cash-flow decisions, while helping you retain more of the rewards of running your business.

How do work-from-home deductions differ by business structure and expense?

The expense is only part of the picture. Your business structure can affect who paid or incurred a cost, which records should support it and which tax return needs to be considered. A sole trader and a company or trust may use the same home office, but that doesn’t mean they claim expenses in the same way. Match each expense to the taxpayer and business arrangement, then apply current Australian Taxation Office (ATO) guidance.

Use this table as an orientation tool, not a final eligibility decision. Requirements depend on the facts and current rules. The IRS home office deduction rules relate to the United States, so they aren’t a guide to Australian claims.

Expense type	Business-use question	Evidence to retain	Verify before claiming
Running costs, such as energy or internet	How much relates to business rather than private use?	Invoices, account statements and work-use records	Applicable method, eligibility and apportionment
Equipment or work-related items	Who uses and owns the item, and for what purpose?	Purchase records and evidence of work use	Who incurred the cost and the relevant tax treatment
Occupancy costs	Is the home area used for business, and under what arrangement?	Relevant property or rental records and calculation notes	Eligibility and any related tax consequences

What should sole traders assess before claiming home-office expenses?

As a sole trader, identify the expense, explain its business purpose, separate private use and gather records to support your calculation. Regularly working from home or setting up a room as an office doesn’t establish eligibility by itself. Apply the current ATO criteria to your circumstances. For more on making informed tax decisions, see our guide to business tax advice in Cairns.

What changes when a company or trust is involved?

A company or trust is a separate business structure, so review how costs are incurred, recorded and treated within that arrangement. Don’t assume an owner’s personal bill automatically becomes a company or trust deduction because it relates partly to work. Review the paperwork and arrangement before lodging the relevant return. This can support more accurate tax planning and better-informed cash-flow decisions.

Assess tax breaks for working from home from a CPA perspective, distinct from a Chartered Accountant viewpoint. A tailored review can bring the business structure, expense and supporting evidence together. Cairns Quality Accounting provides business tax and advisory services to small businesses in the Cairns region.

Does working from home make every household cost tax-deductible?

No. Working from home doesn’t automatically make every household expense deductible. A claim needs to relate to your business activity, meet the applicable Australian Taxation Office (ATO) rules and be supported by evidence. That distinction matters when you’re managing costs that serve both work and home life.

Can you claim a full household bill when it has mixed use?

A shared bill needs careful consideration, not an assumption that the full amount relates to business. Your home internet might support client calls and business tasks, as well as streaming and family use. Electricity may power business equipment and everyday household appliances. Where there’s both business and private use, apportionment means identifying the business-related portion on a reasonable, supportable basis. The appropriate method depends on the expense and current ATO guidance, so keep records that explain your calculation.

A home office doesn’t make every household bill a business deduction. Only an eligible, evidenced business portion may be claimable.

Receipts and account statements show what you paid. Work-use records and calculation notes help explain the business connection. Together, they give a clearer picture than a bill alone. This can also help you avoid claiming private spending and understand how home-working costs affect business cash flow.

Are home-office occupancy costs treated like everyday running expenses?

No. Running expenses, such as the business-related share of energy or internet use, differ from occupancy costs such as rent, mortgage interest or council rates. Don’t assume occupancy costs are claimable simply because you work from home. Eligibility depends on your home, how the space is used, your business arrangement and current tax rules.

Occupancy claims may also raise questions about capital gains tax or the tax treatment of your residence. Those consequences depend on your circumstances, so review current ATO guidance and seek tailored accounting advice before including occupancy costs in a claim. A careful assessment can help you weigh a possible deduction against wider tax considerations.

The IRS home office deduction rules describe United States tax treatment, not Australian rules, so don’t use them to determine an Australian claim. A CPA perspective, distinct from a Chartered Accountant viewpoint, means considering the business purpose, evidence and current ATO guidance together. This practical approach can support confident tax decisions and help you focus on running a healthy business.

How can small-business owners document and review a home-office claim?

A clear record trail makes it easier to explain why an expense relates to your business and how you calculated any work-related portion. It can make tax preparation smoother and help you account for likely deductions in cash-flow planning, rather than leaving the review until lodgement is close.

Use a simple sequence to organise each potential claim:

• Identify the expense. Group it as a running cost, equipment or another relevant expense.
• Establish the business purpose. Note how the cost supports your business activity.
• Record business use. Keep details showing how you separated work use from private use, where relevant.
• Retain supporting evidence. Store invoices, account statements and calculation notes together.
• Review before claiming. Check the method, eligibility and taxpayer responsible for the expense against current ATO guidance.

What records help support work-from-home expenses?

Keep receipts or invoices for costs, along with records that explain the business portion of any mixed-use expense. Depending on the claim, these may include phone or internet statements, work-use records, a log of hours worked at home and notes showing how you calculated the amount. Make notes as you go, especially when a claim depends on usage or work patterns. Records made at the time are easier to rely on than a calculation reconstructed much later.

For the 2025-26 income year, the ATO fixed-rate method is 70 cents per hour worked from home. If you use this method, keep a record of your total actual hours for the full income year, along with at least one record showing you incurred each running expense covered by the rate. Estimates or a representative sample diary aren’t accepted for the hours record. Costs included in the method can’t also be claimed separately under it.

Keep tax-claim records, including hour logs, receipts and calculations, for five years from the date you lodge the tax return. Confirm the current ATO rules for your circumstances, including required records and calculation methods, before lodging.

How should owners prepare before lodging a tax return?

Bring your records together before preparing the return. Group costs by category, reconcile them to business accounts and source documents, and check which taxpayer incurred each expense. Flag uncertain items for review rather than treating them as automatically deductible. If your record system needs attention, our guide to small-business bookkeeping guidance offers a useful starting point.

These steps can make tax breaks for working from home easier to assess and support better-informed tax-minimisation and cash-flow decisions. This is a CPA perspective, distinct from a Chartered Accountant viewpoint. For help reviewing your records and business tax position, speak with the Cairns Quality Accounting team.

How can a Cairns CPA help make work-from-home tax decisions clearer?

Home-office claims can raise several questions at once: which costs relate to business activity, what records support them, and how does your business structure affect the return? A review can bring these details together with current Australian Taxation Office (ATO) guidance, helping you make a considered decision rather than relying on assumptions.

What should a practical CPA review cover?

A practical review can examine your business structure, the expenses you’re considering, evidence of business use and the calculation method relevant to your circumstances. It can also identify where private use needs to be separated or where an expense needs further consideration before inclusion in a claim. The goal isn’t simply to maximise a deduction. It’s to support a claim with a clear business connection and reliable records.

Tax planning should fit the way your business operates. A well-considered expense treatment can help you understand the potential effect on taxable income and cash flow, while avoiding claims that lack evidence. That gives you a steadier basis for decisions about business costs and the rewards you want your work to support.

This guidance is from a CPA perspective. CPA and Chartered Accountant are distinct professional designations, not interchangeable terms. A careful, practical approach can help small-business owners assess tax decisions with confidence.

Frequently Asked Questions

Can small-business owners claim tax deductions for working from home in Australia?

Yes, small-business owners may be able to claim eligible expenses connected with business activity, provided the applicable rules and evidence support the claim. Tax breaks for working from home aren’t automatic, and the right treatment can depend on your structure and the expense. Keep business and private use distinct, and check current ATO guidance. This FAQ reflects a CPA perspective, distinct from a Chartered Accountant viewpoint.

What work-from-home expenses might a small business be able to claim?

Potential expenses include the business-related portion of running costs, such as electricity, gas, phone and internet. Under the 2025-26 fixed-rate method, the ATO rate is 70 cents per hour worked from home and covers specified running costs, including stationery and computer consumables. Eligible work equipment may be considered separately under applicable tax treatment. The expense, business use, records and business structure all matter.

Can I claim electricity and internet if I use them for both business and personal purposes?

You may be able to claim the eligible business-related portion, rather than automatically claiming the full household bill. For example, internet used for business tasks and personal streaming has mixed use. Your calculation needs a reasonable, supportable basis and records that explain how you separated business use from private use. If using the fixed-rate method for 2025-26, electricity and internet are covered by the rate and can’t also be claimed separately under that method.

Can a company claim its owner’s work-from-home expenses?

It depends on who incurred the expense and the business arrangement. A company is a separate structure, so an owner’s personal household bill doesn’t automatically become a company deduction just because it relates partly to work. Review how the cost was paid, recorded and used, and keep supporting documents. Before lodging the company return, assess the treatment against current ATO guidance.

Do I need a dedicated home office to claim work-from-home expenses?

Not necessarily for every type of work-from-home expense. Eligibility depends on the expense, business use, calculation method and current ATO rules. Running expenses and occupancy costs are different categories. A dedicated space used exclusively for business may be relevant when considering occupancy costs, but it doesn’t make those costs automatically deductible. Review your circumstances and the potential tax consequences before including occupancy expenses in a claim.

What records should I keep for work-from-home tax deductions?

Keep invoices or receipts, account statements, records of business use and notes showing how you calculated any business portion. For the 2025-26 fixed-rate method, maintain a record of total actual hours worked from home for the full income year, plus at least one record showing you incurred each expense covered by the rate. Keep tax-claim records for five years from the date you lodge your return, as outlined in current ATO guidance.

Are home-office occupancy costs treated differently from running expenses?

Yes. Running costs include expenses such as energy and internet, while occupancy costs can include rent, mortgage interest and council rates. They have different eligibility considerations, and occupancy expenses aren’t automatically deductible because you work from home. Their treatment may also have consequences for your residence, including capital gains tax considerations. A review can help assess current ATO guidance alongside your business structure and records.
