Work-From-Home Internet Tax Deduction 2026: ATO Guide

A work-from-home internet tax deduction 2026 search often begins with a broadband bill and a guess. The Australian Taxation Office instead asks you to choose an eligible calculation method and keep records that support the work-related amount.

For the 2025–26 income year, the fixed-rate method includes home and mobile internet within the cents-per-hour amount. The actual-cost method may allow the work-related share of internet, but requires a reasonable calculation and evidence. This guide is general information, not personal tax advice.

Quick answer

For a 2025–26 Australian tax return, eligible employees can use the ATO fixed-rate method or actual-cost method for working-from-home expenses. Internet is included in the fixed rate, so it cannot be claimed again separately. Under actual cost, claim only the work-related portion and keep bills, calculations and suitable usage records.

Key takeaways

• Choose one eligible method for the relevant expenses.
• Internet is already included in the fixed-rate method.
• Actual cost requires work/private apportionment.
• Keep contemporaneous records and evidence that you incurred the cost.

Work-from-home internet tax deduction 2026

Start by confirming that you performed employment duties from home and incurred additional running expenses. Casual browsing, checking a roster before leaving home or costs reimbursed by an employer do not automatically become deductible because they occurred online.

The ATO offers fixed-rate and actual-cost methods. Calculate both only if you have the records and entitlement, then use the method that accurately reflects your circumstances. Do not combine methods in a way that claims the same internet cost twice.

How the fixed-rate method treats internet

For the 2025–26 income year, the ATO fixed rate is 70 cents for each eligible hour worked from home. It covers energy, home and mobile internet or data, phone usage, stationery and computer consumables. You need records of actual hours worked from home and evidence of at least one expense in each covered category you incurred.

Because internet is inside the rate, a separate broadband deduction on top would duplicate the expense. Equipment and depreciation may be treated separately where the ATO rules allow; check the current guidance for the item.

How actual-cost apportionment works

Actual cost focuses on the expense you incurred because of work. For a shared unlimited plan, a reasonable work-use percentage may be based on time or data across a representative period, provided the pattern is representative. Bills and a detailed diary support the calculation.

The household context matters. Include private streaming, children’s study, gaming and other users when estimating the total. Remove holidays and periods where the work pattern changed. A neat percentage with no evidence is not stronger than a careful, explainable estimate.

Keep a tax file, not a shoebox

Save broadband invoices, payment evidence, work-hour records, employer arrangements and the spreadsheet or diary used for apportionment. Label the income year and method. Keep originals rather than only totals copied into tax software.

If your work pattern, plan or household changed during the year, split the calculation into representative periods. Seek a registered tax agent or the ATO for advice where facts are complex, particularly for business use, reimbursements or a home that is also a place of business.

Choose the method before assembling the claim

The fixed rate rewards accurate hour records and simplicity; actual cost demands more apportionment. Begin with the ATO eligibility rules and the records already held. Do not reverse-engineer a method merely because one produces a larger number without evidence.

Make a list of expenses covered by the fixed rate and a separate list of items potentially claimed outside it under current rules. This prevents internet, phone, energy or stationery from appearing twice in different labels inside tax software.

Build a representative internet diary

For actual-cost analysis, record who uses the service, when, for what purpose and—where practical—the data involved. Include streaming, gaming, schoolwork, personal browsing, smart devices and other workers. A household internet bill is mixed-use evidence, not a ready-made work deduction.

Choose a period that genuinely represents the year. If the household changes plan, someone moves in, school holidays alter use or employment patterns shift, one four-week sample may not fairly describe everything. Split the year or keep fuller records where necessary.

Explain the calculation to your future self

Save a note showing the formula, dates, exclusions and why the period was representative. Link each total to a bill or receipt. A calculation that another person can follow is easier to review than a percentage typed directly into a return months after the analysis.

Tax records contain account and household information, so store them securely. Keep only what supports the claim and follow ATO retention guidance. If the bill is in another person’s name or cost-sharing is informal, get advice about whether you actually incurred the expense.

A worked household example

Jordan works from home two days a week and pays the shared family internet bill. Under the fixed-rate method, eligible internet use is already covered by the hourly rate, so Jordan keeps bills and actual work-hour records but does not add a separate internet claim. When testing actual cost, Jordan records all family use over a representative four-week period rather than treating the entire unlimited plan as work-related.

The example shows a decision method rather than a promised saving, technical result or tax outcome. Replace every assumed price, speed, device requirement and household routine with current written information for your address. Promotions can end, providers can change terms, and a speed available to one connection may not be available to another.

A household review before you finish

Reconcile the chosen method with the numbers entered in the return. If using the 70-cent fixed rate for 2025–26, make sure the same home or mobile internet expense has not reappeared under another label. If using actual cost, make sure the work percentage and claimed months match the diary, bills and periods actually worked.

Households with two people working from home should keep each person's records separate. One bill can support more than one person's calculation, but that does not make the total cost available twice. Record who paid, how costs were shared and how each person's work use was established. Seek advice where ownership or reimbursement is unclear.

Before lodging, download the current ATO page or save a dated note of the rule relied on. Rates and labels can change between income years, and search results may surface older guidance. Review the calculation with a registered tax agent if the amount is material or the home is also used to run a business.

Once the return is lodged, preserve the calculation and supporting records in the same folder as the lodged figures. Do not discard the usage diary because the refund arrived. For 2026–27, begin fresh hour and expense records from 1 July rather than carrying forward a percentage automatically. A new income year can bring a new rate, plan, employer arrangement or household pattern. Record changes when they happen so next tax time does not depend on rebuilding twelve months from memory.

Your action checklist

• Confirm eligibility.
• Choose fixed rate or actual cost.
• Record actual WFH hours.
• Keep broadband bills and payment evidence.
• Document any work/private apportionment.
• Avoid duplicate claims.

Questions worth asking before you act

• Which method am I eligible to use?
• Is internet already included?
• Is my diary representative?
• Did another household member pay the bill?
• Was any cost reimbursed?

Ask for material answers in writing and save the critical information summary. Keep screenshots of time-limited offers, order confirmations, equipment terms, return tracking and complaint numbers. If a disagreement occurs later, a short paper trail is more useful than trying to reconstruct a sales conversation.

Technology and address notes

The tax treatment does not depend on whether the connection is NBN, home wireless or mobile data. It depends on eligibility, who incurred the expense, the chosen method, work-related use and evidence. Check current ATO guidance before lodging.

Australia's home internet market includes NBN fixed line, Fixed Wireless, satellite, non-NBN fibre, 4G and 5G home internet and mobile broadband. Availability and real-world performance vary by address, technology, provider network, plan and in-home equipment. Always run the address check and read the current plan summary before relying on a national article.

Common mistakes to avoid

• Claiming the whole household bill as work-related.
• Adding internet again on top of the fixed rate.
• Using estimated hours without required records.
• Claiming costs reimbursed by an employer.
