Tax treatment of ERP spending in Australia: SaaS subscriptions, implementation and the instant asset write-off
How SaaS subscriptions, licences, implementation work and hardware are generally treated for Australian tax, the $20,000 small business instant asset write-off, GST credits and where to check.
In general terms, a cloud ERP subscription used to run your business is a revenue (operating) expense, deductible in the income year it is incurred, because you are paying for a service rather than acquiring an asset. Software you acquire or develop for your own use (in-house software, such as a perpetual on-premise licence or substantial custom development) is generally a depreciating asset, with a statutory effective life of five years, unless a small business concession lets you write it off sooner. Eligible small businesses with aggregated turnover under $10 million can use the instant asset write-off for eligible assets costing less than $20,000 each. Implementation costs sit in a grey area and depend on what the work creates. This guide sets out the general principles; confirm your own treatment with a registered tax agent.
This guide is part of the ERP selection checklist series. It is general information, not tax advice.
The main categories of ERP spending
| Spending | General tax character | Notes |
|---|---|---|
| Cloud subscription (SaaS) fees | Usually revenue expense, deductible when incurred | Prepayments covering more than 12 months may be subject to prepayment rules; small businesses have concessions |
| Vendor support plans | Usually revenue expense | |
| Perpetual on-premise licence | Usually a depreciating asset (in-house software) | Small business write-off or simplified depreciation may apply |
| Custom software developed for your own use | Usually in-house software, depreciated | Development pools have their own rules |
| Implementation of a SaaS product (configuration, data migration, training) | Depends on the facts | Training and data cleansing are often revenue; work creating a separate asset may be capital. Ask your tax agent |
| Servers, laptops, scanners | Depreciating assets | Instant asset write-off may apply per asset |
| Partner support retainer | Usually revenue expense |
The distinction matters most for large implementation bills. A $90,000 implementation that is deductible immediately has a very different cash effect from one depreciated over five years.
The instant asset write-off
For eligible small businesses using the simplified depreciation rules (aggregated turnover under $10 million), the instant asset write-off allows an immediate deduction for the business portion of eligible depreciating assets costing less than $20,000 each.
- The threshold applies per asset, so several assets each under $20,000 can each be written off.
- For a GST-registered business, the cost is generally measured excluding the GST you can claim back.
- Assets costing $20,000 or more generally go into the small business simplified depreciation pool.
- The asset must be first used or installed ready for use within the relevant period.
Status in 2026: the $20,000 threshold applied for 2025–26 (1 July 2025 to 30 June 2026). The government then made the $20,000 threshold ongoing for assets first used or installed ready for use on or after 1 July 2026: the Treasury Laws Amendment (Tax Reform No. 2) Act 2026 (No. 71, 2026) became law on 26 August 2026. Check the ATO's instant asset write-off page for the current conditions before you rely on it.
Illustrative example: a small business (turnover $4 million, GST-registered) buys a perpetual licence for a warehouse module at $15,400 including GST and two barcode scanners at $2,200 each including GST. Excluding GST, the costs are $14,000 and $2,000 each. Each asset is under $20,000, so each may qualify for the write-off in the year it is first used or installed ready for use, assuming the business uses simplified depreciation and meets the other conditions. Its annual cloud subscription of $36,000 is generally deductible as an operating expense anyway.
Subscriptions paid in advance
Many ERP contracts ask for a year upfront. Paying 12 months in advance in June can bring the deduction forward for some taxpayers. Small businesses and individuals not carrying on a business generally have a concession for prepayments covering a period of 12 months or less that ends before the end of the next income year; other taxpayers may have to spread the deduction. Ask your tax agent before timing payments for tax reasons.
GST credits
- Australian suppliers and partners registered for GST charge 10% GST; a GST-registered business generally claims it back as an input tax credit with a valid tax invoice.
- Overseas digital service suppliers should not charge GST if you give your ABN and state you are GST-registered; see USD pricing, FX and GST.
- Businesses making input-taxed supplies may not be able to claim full credits.
Accounting treatment is a separate question
Financial statements prepared under Australian Accounting Standards follow accounting rules, not tax rules. For cloud computing arrangements, the IFRS Interpretations Committee's April 2021 agenda decision (applied in Australian practice; check with your accountant) means that configuration and customisation costs of SaaS are often expensed rather than capitalised unless they create a separate asset you control. Your accountant will advise on how this applies to your project and reporting. Tax and accounting treatment can differ.
Government support
The federal Digital Solutions program under the Australian Small Business Advisory Services initiative has offered low-cost or free advice on business software, cyber security and online tools; at the time of writing it provides advice through regional providers rather than cash grants. State governments run small business advisory services and occasional digital or productivity grants, which open and close frequently. Search the grants finder on business.gov.au and your state's small business portal for current programs. Do not assume a grant will be available when you budget.
Building tax into your numbers
The payback calculator and TCO estimator work on pre-tax amounts. For an after-tax view, ask your tax agent to estimate the timing of deductions for each cost line, then compare after-tax cash flows. Use the TCO worked example as the cost base and the payback example for savings.
Frequently asked questions
Is our ERP subscription tax deductible?
Generally yes, as an operating expense of running the business, in the year it is incurred. Prepayments may follow special rules.
Can we write off an ERP implementation immediately?
It depends on what the work produces. Training and some configuration may be deductible; work creating a capital asset may need to be depreciated. Ask your tax agent.
Does the instant asset write-off apply to software?
It can apply to eligible depreciating assets, which can include in-house software you acquire, if your business is eligible and the other conditions are met. Subscriptions are not assets and are usually deducted anyway.
Is the $20,000 threshold permanent?
It is now ongoing: the Treasury Laws Amendment (Tax Reform No. 2) Act 2026 made the $20,000 threshold apply from 1 July 2026 without an end date. Future Parliaments can still change it, so check the ATO website before you rely on it.
