A tax depreciation schedule is one of the most effective ways to improve your after-tax cash flow without having to raise rent, cut corners, or take on extra risk. Yet, many investors either don’t have one, or are unsure what a comprehensive schedule should include.
Washington Brown’s tax schedule guide is here to change that!
In clear terms and with meticulous accuracy, we explain what a property tax depreciation schedule is, what it should include, and who benefits from it. But, perhaps most importantly, it outlines how much you might be able to claim.
Washington Brown is Australia’s depreciation schedule expert, backed by more than 315,000 accepted reports and over 45 years of quantity surveying experience. We help valued investors elevate cash flow, boost portfolios, and create long-term wealth … all with ATO-compliant schedules.
What Is a Property Tax Depreciation Schedule?
Over time, every building suffers from wear and tear. Australian tax law understands this and therefore allows property investors like you to claim a deduction for that deterioration … as long as your property is used to produce income.
A property tax depreciation schedule outlines how much of that wear and tear you can claim each year, based on the decline in value of:
Capital Works (Division 43)
The structural parts of the building, usually claimed at a fixed rate each year over a 40-year period.
Plant & Equipment (Division 40)
Assets that are easily removable or mechanical, claimed over their effective lives in line with ATO guidance.
Your accountant uses this schedule when they prepare your tax return to claim non-cash deductions. Those deductions reduce your taxable income from the property. This can generate:
Tax depreciation schedules can be prepared for residential investment properties, commercial properties, and mixed-use properties with both residential and
What a Quality Tax Depreciation Schedule Should Include
Not all tax depreciation reports are the same. To stand up to serious ATO scrutiny, a specialist report must include
Clear property details
Address, property type, construction year, settlement date, ownership entities, and the date it was first available for rent.
Legislative basis and methods used
Relevant legislation, ATO rulings, and methods … for example, Prime Cost and Diminishing Value.
Construction cost
Actual building costs where available, professionally estimated costs if those records aren’t on hand.
Detailed Capital Works schedule (Div 43)
Eligible structural elements and improvements, and year-by-year deductions over the allowable period.
Detailed Plant & Equipment schedule (Div 40)
Eligible assets, opening values and effective lives, and annual deductions for each asset.
Year-by-year summary table
Showing total deductions for each financial year, the page most investors and accountants refer to at tax time.
Assumptions and notes
About usage, effective lives, renovations and ownership, so the report can be understood and defended if questions arise.
At Washington Brown, we don’t just meet these standards, we exceed them. Every single report is backed by our TaxMax500™ quality assurance process … cross-referencing over 500 variables to ensure no stone is left unturned.
And, as Registered Tax Agents and members of the Australian Institute of Quantity Surveyors (AIQS), our reports are legally robust documents designed to be ‘accountant-ready’. With over 45 years of quantity surveying experience and a 100 percent ATO acceptance rate, we provide the ultimate reassurance … you know that your claims are both maximised and bulletproof.
Who Benefits Most From a Depreciation Schedule?
Every property and investor is unique, but the goal remains the same … ensuring your asset works as hard for you as possible. A tax depreciation schedule isn’t an optional report … for many, it’s the difference between a property that costs money each month and one that is cash-flow positive.
Whether you’re a first-time investor or managing a large-scale commercial portfolio, a tax depreciation schedule is essential for:
New/near-new residential property
Recent construction often means substantial building write-off and modern fixtures that qualify as Plant & Equipment.
Significant renovations or extensions
New kitchens, bathrooms, extensions, decks and structural work can inject fresh depreciable value into an older dwelling.
Commercial and industrial property
Offices, warehouses, retail and industrial premises often have substantial Capital Works and specialised Plant & Equipment.
Older properties with documented improvements
Renovations and improvements by you or even previous owners can support valuable claims.
A dedicated and knowledgeable specialist, such as Washington Brown, will help you screen properties up front … so you can avoid paying for a report where there is little or no benefit.
How Much Can I Save With a Tax Depreciation Schedule?
The exact amount depends on the age, type, construction cost and use of your property … but, in many cases, investors are able to claim thousands of dollars in deductions each year.
An expertly prepared tax depreciation schedule can:
- Turn a negatively geared property into a positive one
- Improve after-tax cash flow on a new purchase
- Help you retain properties during periods of higher interest rates
This estimate uses real-world purchase price data.
How Your Tax Depreciation Schedule Is Calculated
Calculating depreciation is a complex process, requiring construction cost estimation and up-to-date tax law knowledge. It isn’t just some numbers … it’s about identifying and categorising every single dollar of value in your asset to meet strict ATO standards.
At Washington Brown, our specialists follow a rigorous five-step process to ensure your claim is both maximised and bulletproof:
Comprehensive Data Analysis
We begin by analysing every available aspect of your property, including architectural plans, construction contracts, council records and purchase details. We also look for evidence of past renovations … even if completed by previous owners … which are often missed by investors and their accountants!
Expert Construction Cost Estimation
This is where the law is seriously strict. Under Taxation Ruling TR 97/25, if the actual construction cost of a property is unknown, the ATO requires a specific qualified person, such as a Quantity Surveyor, to estimate it. We use our vast database of historical building records to provide a precise valuation that stands up to ATO scrutiny.
Asset Classification (Div 40 vs Div 43)
We carefully separate the building’s bricks and mortar (Division 43) from the removable fixtures and fittings (Division 40). Getting this split right is essential, as these items depreciate at completely different rates.
Strategic Depreciation Modelling
We calculate your deductions using both the Diminishing Value and Prime Cost methods. Our goal is to match the report with your specific financial strategy … whether you want to maximise immediate cash flow or achieve steady, long-term deductions.
Final ATO-Compliant Report
You get a comprehensive, 40-year forecast from the property’s original construction date that’s ready for your accountant to use. Our reports are itemised and clearly summarised so your tax agent can use the figures directly in your return without further calculation.
Important Note: Because the above process requires estimating historical construction costs and interpreting shifting tax legislation, the ATO requires it to be performed by a qualified specialist. Accountants, real estate agents, and investors are not legally permitted to perform these construction cost estimates.
What Does a Depreciation Schedule Cost … And Is It Worth It?
At Washington Brown, we believe that a tax depreciation schedule shouldn’t just be another expense. While the actual fee for a professionally completed report depends on your property type, location, and the complexity of the assets involved … the focus for you as an investor is what the report gives back to you.
Our powerful tax depreciation schedules can:
- Pay for itself – most investors regain the cost of the report within the first year through significantly higher tax refunds or lower tax bills.
- Deliver 40 years of value – a single report can provide up to four decades of deductions for the same property, if no further upgrades are undertaken.
- Remove audit risk – we deliver the professional construction cost estimates required by TR 97/25, protecting you from ATO penalties for DIY errors.
- Be 100% tax deductible – the fee for the schedule is usually claimable as a tax deduction in the year you purchase it.
We are so confident we can maximise your claims, we offer an industry-leading promise! For properties built after 1987, we guarantee to find at least twice our fee in tax deductions within the first 12 months, or there will be no charge.
Put simply, your first-year deductions will be at least double the cost of the report, or you pay nothing. That is the level of certainty our experience brings to your portfolio.

My depreciation report was done quickly and efficiently. The staff at Washington Brown responded to my enquiries quickly, and were professional and helpful throughout the process. Highly recommend!
Becky Carline
The items in the report were more than I was hoping for, and in fact my capital works total depreciation amount will be 3 times what I paid for the report – in the first year alone. So, the overall experience with WB exceeded my expectations – professionalism and the works done faster than expected greatly contributed to this outcome.
Michael Busc
I have used WB for multiple depreciation reports. The reports are completed promptly with excellent detail. I have found the cost to be very competitive and great value for money. Couldn’t recommend more.
Joshua Bell
They were fast to quote, communicate necessary details to me and agreed to conduct the necessary in-person inspection within 4 business days at my address within an hour of Sydney (much faster than others, who in one case quoted 6 weeks!). This made my selection easy.

You and Your Accountant Use It Each Year

Frequently Asked Questions About Tax Depreciation Schedules
No! You can still claim all the future deductions for the remaining life of the building, for 40 years from the property’s construction date or any more recent renovations. What’s more, your accountant can often backdate your claims by amending your tax returns for the previous two years … regaining missed cash flow.
No. Under TR 97/25, the ATO requires appropriately qualified professionals … typically Quantity Surveyors … to estimate construction costs where the actual costs are unknown. The ATO doesn’t accept DIY estimates for structural claims, and using a non-compliant report could expose you to heavy penalties and audits.
Don’t assume that “old” means “no value”! While the original structure might be past the 40-year claim limit, you could still claim on previous renovations … even those done by past owners … and any new assets you’ve installed. We specialise in investigating older terraces and houses to find these hidden deductions.
If you do some renovations while your property is income-producing, you should immediately get your tax schedule updated. This allows you to claim scrapping deductions … where you write off the remaining value of items you’ve demolished as an instant 100 percent tax deduction … while starting new claims on the improvements.
Yes, as long as the property is genuinely available for rent. Under the latest ATO rules, you must apportion your claims based on the number of days the property was available to guests compared to private use. We provide specialised reports that make this calculation easy for your accountant.
