Can You Claim a Laptop, Mobile Phone and Internet on Tax in Australia?

October 9, 2026    admin

Laptops, smartphones and internet connections are part of everyday working life for many Australians. Employees may use them to complete tasks outside the office, while sole traders and business owners often rely on digital devices to manage customers, prepare documents and keep their operations running.

These expenses can raise questions at tax time. Can you claim the cost of a new laptop? Is part of your monthly phone bill deductible? What happens when your home internet is used for both work and personal activities?

The answer depends on how you use each item, the type of expense and the tax rules that apply to your circumstances. Understanding these differences can help you prepare a more accurate tax return and avoid claiming amounts you are not entitled to deduct.

Can a Laptop Be Claimed as a Tax Deduction?

A laptop may qualify for a tax deduction when it is used for eligible employment duties or business activities. However, purchasing a computer does not automatically mean you can claim its entire cost.

Consider an employee who uses a personal laptop to prepare work reports, attend online meetings and complete tasks outside normal office hours. If the computer is also used for personal activities, such as gaming, shopping or watching videos, the private-use portion generally cannot be claimed as a work-related deduction.

The same principle applies to business owners. A laptop used to manage orders, communicate with customers or prepare business documents may have a deductible business-use component. The claim should reflect its actual eligible use and be supported by appropriate records.

Does the $300 rule apply to laptop purchases?

For employees, an eligible work-related item costing $300 or less may qualify for an immediate deduction if the relevant conditions are satisfied. The item must meet the applicable requirements, including those relating to its connection with earning employment income and private use.

When a laptop costs more than $300, its cost will generally be claimed over time through depreciation rather than deducted in full immediately. Eligible businesses may have access to different depreciation concessions, depending on the rules and thresholds applying to the relevant financial year.

Because employees and businesses can be subject to different arrangements, check the current Australian Taxation Office (ATO) guidance before deciding how to treat a computer purchase.

Are Mobile Phone Expenses Tax-Deductible?

Your mobile phone may be used for a mixture of professional and personal activities. You might call customers, respond to work messages, use business applications and participate in meetings during the day, then use the same device to contact family and friends.

Where the phone is used for eligible work purposes, you may be able to claim the relevant portion of certain expenses. This can include part of your phone plan and, where the requirements are met, the cost of the handset.

For example, a consultant who uses a personal mobile to communicate with clients may have a deductible work-related portion of their phone expenses. However, claiming the entire monthly bill would not be appropriate if the plan also covers personal calls, messages and browsing.

How should you calculate work-related phone use?

Your calculation should be reasonable and reflect how you actually use the phone. Depending on your circumstances, phone bills, usage records and a diary covering a representative period may help support the percentage you claim.

Avoid choosing a percentage simply because it seems convenient. If you claim part of your phone expenses, you should be able to explain how you calculated that amount.

You should also check whether your employer reimbursed any costs or supplied the device. These arrangements can affect whether you personally incurred an expense that is deductible.

Can You Claim Home Internet on Tax?

Home internet can support work activities such as video conferences, online research, accessing workplace systems and communicating with clients. However, a household connection is usually used for other purposes as well.

If you work from home, the full internet bill does not automatically become deductible. You generally need to identify the eligible work-related portion and keep records that support your calculation.

For instance, an employee might use their connection to access work systems during business hours, while other household members use it for study, streaming and personal browsing. The claim needs to reflect the taxpayer’s eligible use rather than the total household activity.

Keep copies of your internet bills and records explaining how you calculated the work-related share. The method you use should be reasonable for your situation and consistent with the applicable ATO requirements.

What Changes When You Work From Home?

Working from home may involve additional running expenses beyond the purchase of a laptop or the cost of an internet plan. Depending on the circumstances, eligible expenses may include electricity and certain phone or internet costs.

The ATO provides different methods for calculating working-from-home deductions. The fixed-rate method and actual-cost method have their own conditions and record-keeping requirements.

Under the fixed-rate method, the applicable rate covers specified running expenses. If phone or internet costs are included, you cannot claim those same covered expenses separately again for the same work-related use.

The actual-cost method requires you to calculate eligible expenses using the relevant records and work-related proportions. Which approach is appropriate depends on your circumstances and the evidence available.

Before selecting a method, check the current requirements for the income year you are claiming. You should also confirm that your working arrangements satisfy the relevant eligibility conditions.

For official information, visit the ATO’s working-from-home expenses guidance.

Tax Deductions for Small Business Owners and Sole Traders

People running a business may use the same laptop, mobile phone and internet connection for both business and personal purposes. They may need to consider the business-use portion, the treatment of equipment purchases and the records required to support their claims.

For example, a sole trader may use a laptop to prepare invoices, maintain bookkeeping records and communicate with customers. If the device is also used privately, the eligible business portion needs to be assessed under the applicable rules.

Small Business Tax Accountants can help business owners understand how equipment costs, depreciation and mixed-use expenses may be treated for tax purposes. A Sole Trader Tax Accountant may also assist with reviewing eligible business expenses and establishing record-keeping practices that support accurate reporting.

The correct treatment can depend on the business structure, the item’s cost, the date it was acquired and any concessions available. Do not automatically apply the same rules used for an employee’s personal tax return to a business expense.

What Records Should You Keep?

Supporting documents help explain why you claimed an expense and how you calculated the amount. Organising these records throughout the year is generally easier than trying to reconstruct your usage when your tax return is due.

Depending on the expense, useful records may include:

  • Receipts and invoices for laptops, phones and related equipment.
  • Mobile phone and internet bills showing the costs paid.
  • A diary or other evidence supporting your work-related usage estimate.
  • Notes explaining how you separated private use from work use.
  • Details of any employer reimbursements or business payments.
  • Records showing the connection between the expense and your income-producing activities.

For example, if you claim a portion of your annual mobile phone costs, your records should explain how you arrived at that figure. A percentage without a reasonable basis may be difficult to substantiate if the ATO requests supporting information.

Keep records for the period required under the applicable tax rules. The exact requirements can vary depending on the type of claim and your circumstances.

Common Mistakes to Avoid When Claiming Technology Expenses

One mistake is assuming that every device used for work is fully deductible. Personal use can reduce the eligible amount, even when the device is important to your job or business.

Another issue is treating equipment purchases and ongoing service charges as though they follow identical rules. A laptop’s purchase price may be treated differently from a monthly internet subscription or phone plan.

Duplicate claims are also worth checking. If a working-from-home method already covers a particular running expense, claiming the same expense again separately for the same use can result in an incorrect deduction.

Finally, do not copy a deduction percentage from another person. Your working arrangements, device usage and eligibility may be different, so your calculations should reflect your own circumstances.

When Should You Speak to a Tax Accountant?

If you are uncertain about a laptop’s depreciation, the work-related share of your phone bill or the correct treatment of home internet, professional advice may help clarify the rules.

A Personal Tax Accountant can help employees understand eligible work-related deductions and the evidence needed to support their claims. Business owners may benefit from advice that considers their business activities, equipment purchases and record-keeping responsibilities.
