A depreciation schedule is a report that lists an asset's cost, its effective life and the depreciation you can claim against income each year.

Also known as: tax depreciation schedule, quantity surveyor report, capital allowance schedule

Key points

  • The schedule lists each asset you own, what it cost, how long it should last and the deduction for each year.
  • Property investors usually buy one from a quantity surveyor, covering capital works on the building as well as plant and equipment items.
  • Businesses often keep the same detail in an asset register, using either the straight line or diminishing value method.
  • It is a record for your tax return, not a bill: it does not change what you paid or what you owe a lender.
  • A schedule only helps where the asset earns assessable income, so any private use has to be taken out.

Frequently asked questions

How does a depreciation schedule work?

A quantity surveyor or accountant lists every depreciating item, its cost and its effective life, then calculates the deduction for each year you own it. You give the schedule to whoever prepares your tax return, and the same document is used year after year until the assets are fully written off.

Who prepares a depreciation schedule?

For a rental property it is usually a qualified quantity surveyor, because estimating historical construction costs is their specialty rather than an accountant's. For business assets your accountant or bookkeeper can build the schedule from purchase invoices, since the cost of each item is already known.

Is a depreciation schedule tax deductible?

The fee for preparing a schedule is generally deductible as a cost of managing your tax affairs, in the year you pay it. That is separate from the depreciation the schedule lets you claim. Confirm the treatment with your accountant, because it depends on how the property or asset is used.

Do I need a depreciation schedule for an older property?

Often yes, but the benefit is usually smaller. Older buildings may fall outside the capital works period, and second-hand plant and equipment in an established residential property is restricted. Many surveyors will estimate the likely claim before you commit, so you can see whether it is worth ordering.

How long does a depreciation schedule last?

One schedule normally covers the full life of the assets, so you do not reorder it each year. You update it when you renovate, replace an appliance or scrap something, and your accountant adjusts the figures if the property stops being rented out.
