Depreciation Planning

Using the register to forecast CAPEX, cashflow and the timing of deductions.

A well-maintained asset register is more than a compliance tool. It supports capital expenditure planning, insurance decisions, and tax strategy.

Can I use my fixed asset register to plan future capital expenditure?

Yes. This is one of the most underused applications of the fixed asset register.

If the register records when each asset was acquired and what its effective life is, you can calculate when each asset will reach the end of its useful life and estimate what it will cost to replace.

This gives you a rolling capital expenditure forecast that can be planned and financed in advance, rather than managed reactively when equipment breaks down.

How does depreciation affect my insurance coverage?

The written-down value of an asset in your accounts is almost never the right basis for insurance.

Replacement cost, what it would cost to buy a new equivalent asset today, is what matters for most insurance purposes. For assets that have been written off for tax (WDV = zero) but are still in productive use, the gap between book value and replacement cost can be enormous.

Using book value as the basis for an insurance claim may leave the business significantly underinsured.

Should I self-assess a shorter effective life for my assets?

It depends on how you actually use them. If your assets are used more intensively or in harsher conditions than the ATO’s standard table assumes, you can self-assess a shorter effective life and claim higher depreciation deductions earlier.

The trade-off is that a shorter effective life depletes the WDV faster, meaning balancing adjustments on disposal will be higher if the asset retains market value.

Self-assessed lives should be documented and supportable if the ATO reviews them.

For accountants

Self-assessment of effective life is permitted under section 40-105. The taxpayer must have reasonable grounds for the self-assessed life. Relevant factors include the intensity of use, the operating environment, the maintenance regime, and the taxpayer’s history with similar assets. The ATO’s review process for self-assessed lives focuses on whether the original assessment was reasonable, not whether it turned out to be accurate.

What is the best way to track both tax and accounting depreciation?

The most reliable approach is a system that maintains both schedules simultaneously on a per-asset basis.

For each asset, the system should record the original cost, acquisition date, method chosen for tax, method chosen for accounting, effective life for tax, useful life for accounting, and the running WDV for each basis.

Spreadsheets can do this in theory but are prone to formula errors, version control problems, and the loss of institutional knowledge when the person who built them leaves. Purpose-built depreciation software is designed to solve exactly this problem.

What is an SBE pool and is it right for my business?

The small business pool is a simplified way of depreciating assets for tax purposes. Eligible assets are grouped into a single pool and depreciated at set rates (15% in the first year, 30% thereafter), rather than tracking each asset individually.

This reduces the compliance burden around tax depreciation but comes with a significant trade-off: once assets are in the pool, you cannot determine the individual WDV of each asset.

This makes insurance reviews, CAPEX planning, borrowing, and regulatory compliance harder. Whether it is right for your business depends on whether the tax simplification benefit outweighs those information costs.

For accountants

The Division 328 pooling rules apply to all eligible businesses that have elected simplified depreciation. Once elected, the business is generally locked in for five years under section 328-175 unless the ATO grants an exit. The interaction between the pool and the instant asset write-off threshold is worth watching, because the pool’s role changes with it. At the $20,000 threshold, most lower-value assets bypass the pool entirely and are written off immediately, limiting the pool to mid-range and higher-value assets. Because the threshold is set by income year and has moved repeatedly, a business can see a materially different result for the same spend from one year to the next.
