For New Zealand businesses evaluating their fixed asset and lease accounting setup, Xero’s built-in fixed asset module is often the starting point. As a native part of Xero, it has a real integration advantage — and for organisations with straightforward needs, it works well. But for NZ clients with more complex requirements, the built-in module has material gaps that are worth understanding clearly.
This article sets out where Xero’s fixed asset module is sufficient, where it falls short, and when a specialist platform like AssetAccountant is the more appropriate solution.
When Xero fixed assets is likely sufficient
Xero covers the basics solidly. It supports straight-line and diminishing value depreciation, handles the $1,000 low-value asset threshold, and now includes support for Investment Boost — the 20% partial expensing measure for eligible new assets from May 2025, which Xero added to its platform in September 2025.
For a small New Zealand business with a modest, stable asset register, no lease accounting obligations, and straightforward depreciation needs, Xero is often enough. It auto-creates draft assets from bills and bank transactions, maintains a tax value book per asset separate from the book value (the correct treatment — tax depreciation does not post to the GL), and sits natively inside the platform most NZ businesses already use.
If your organisation has fewer than approximately 500 assets, does not require IFRS revaluation or impairment treatment, and is comfortable manually entering IRD rates for each asset type, Xero’s built-in module can handle your needs.
Where Xero starts to break down
IRD tax depreciation rates are not pre-loaded
Xero does not pre-load IRD effective life rates from IR265. Users must manually enter the correct depreciation rate for each asset type — there is no built-in rate lookup. This creates a risk of error and adds overhead, particularly for organisations with varied asset classes.
Xero also does not automatically apply the 0% depreciation rate for non-residential buildings that has been in effect since the 2024/25 income year. That rate must be set manually.
AssetAccountant pre-loads and annually maintains the full IRD rate table (IR265), includes a built-in rate lookup, and automatically applies the 0% building rule for the relevant asset type.
No support for revaluations or impairments
Xero’s fixed asset module does not support revaluations or impairments under NZ IAS 16 and NZ IAS 36. This is a long-standing gap, documented in Xero’s product community and unresolved as at 2025.
For any New Zealand entity on the revaluation model — property companies, infrastructure entities, and others required to carry assets at fair value — Xero cannot serve as the sole fixed asset solution.
AssetAccountant supports revaluations and impairments, including bulk processing, with the revaluation reserve journaled automatically. It also offers an explicit GAAP vs IFRS option on accounting books, whereas Xero operates on a single accounting book only.
No native lease accounting
Xero has no native IFRS 16 module. New Zealand clients with lease accounting obligations — those required to recognise right-of-use assets and lease liabilities on the balance sheet — must use a separate third-party application, which then integrates back to Xero’s GL.
AssetAccountant includes IFRS 16-compliant lease accounting as a separately priced add-on within the same platform as fixed assets. It also handles asset finance loans (hire purchase) natively. Fixed assets, leases, and asset finance loans share GL account mapping and journal to Xero in a single process — no separate tool required.
Register size and scalability
Xero’s fixed asset module has a soft cap of approximately 500 assets. For organisations with larger registers, this becomes a practical constraint.
AssetAccountant imposes no asset limit. Current clients include registers of up to 50,000 assets.
Partial disposals, multi-book depreciation, and depreciation methods
Xero does not support partial disposals — another long-standing community request that remained undelivered as at 2025. It also operates on a single accounting book only, with no ability to maintain different cost bases, rates, or dates across multiple books.
AssetAccountant supports partial disposals and partial write-offs, multi-book depreciation with different cost bases and rates per book, and units-of-use (activity-based) depreciation. It also supports non-monthly depreciation periods, which Xero does not explicitly accommodate.
Asset data and record management
Beyond the headline compliance gaps, there are meaningful differences in how the two platforms handle asset records.
Xero does not support custom fields — there are no user-defined fields per asset. It does not support attachments within the fixed asset module, and assets cannot be structured as components of other assets.
Xero’s tracking categories are also limited to two per organisation, which is a platform-wide constraint. This limits how assets can be classified and reported across departments, locations, or cost centres.
AssetAccountant supports unlimited custom fields per asset, unlimited attachments per asset, and allows assets to be marked as components of other assets. It syncs with Xero’s tracking categories and supports unlimited asset classifications within the platform itself.
Lease accounting in more detail
For NZ entities applying NZ IFRS 16, the absence of a native lease module in Xero is a significant gap. The typical workaround — a standalone lease application feeding journals back to Xero — creates friction: separate GL account mapping, a separate subscription, and a separate reconciliation process.
AssetAccountant handles this within the same platform. The lease module calculates the right-of-use asset and lease liability, handles the current/non-current liability split, and journals directly to Xero alongside fixed asset depreciation. Asset finance loans (hire purchase) follow the same workflow. For clients with both owned assets and leased assets to manage, having both in one place — with shared GL mapping — reduces complexity meaningfully.
Forecasting and reporting
Xero’s reporting strengths sit at the accounting system level — integrated P&L and balance sheet reporting is a genuine advantage of the native platform.
At the fixed asset level, Xero provides a depreciation schedule showing depreciation by asset. There is no tax audit report and no portfolio-level forecasting capability.
AssetAccountant includes a dedicated tax audit report and supports 100-year portfolio-level depreciation forecasting — relevant for capital planning and infrastructure clients managing long-lived assets.
What this looks like in practice
Two clients. Both are Xero users.
Client A is a small trading company with 80 assets, no lease obligations, and straightforward accounting depreciation needs. Their accountant enters IRD rates manually when adding assets. Xero handles this cleanly. There is no case for a specialist platform here.
Client B is a property and infrastructure group. They hold 1,400 assets across several entities, carry property on the revaluation model under NZ IAS 16, have a portfolio of operating leases requiring IFRS 16 treatment, and need IRD tax depreciation calculated automatically against the correct IR265 rates. Xero cannot serve this client from its fixed asset module alone — the revaluation requirement rules it out as the sole solution, let alone the lease accounting obligations and register size.

For NZ clients with more complex requirements, AssetAccountant provides:
- Full IRD rate content (IR265) pre-loaded and maintained annually, with built-in rate lookup
- Automated Investment Boost (20% deduction) and automatic application of the 0% non-residential building rule from 2024/25

AssetAccountant is built for direct use by finance teams and management accountants. The asset register provides a period-by-period view of book values, additions, depreciation, disposals, and movements across every asset class — without requiring specialist implementation support.
How AssetAccountant works with Xero
AssetAccountant is not a replacement for Xero — it works alongside it. The platform has a dedicated Xero integration. Fixed asset depreciation, lease journals, and asset finance journals are posted to Xero’s GL via one-click journal posting. Draft assets are automatically generated from Xero GL transactions in fixed asset accounts, equivalent to Xero’s own auto-draft workflow.
The two platforms work together: Xero handles the accounting system, AP, and reporting; AssetAccountant handles the fixed asset register, tax depreciation, and lease accounting at the depth NZ compliance requires.
When to use each
Xero fixed assets is likely sufficient if:
- You have fewer than approximately 500 assets
- You have no NZ IFRS revaluation or impairment requirements
- You have no IFRS 16 lease accounting obligations
- You are comfortable manually entering IRD depreciation rates
AssetAccountant is the better fit if:
- You need revaluations or impairments under NZ IAS 16 / NZ IAS 36
- You need IRD-compliant tax depreciation with pre-loaded IR265 rates
- You have IFRS 16 lease accounting obligations and want these managed in the same platform as fixed assets
- You manage more than approximately 500 assets
- You need partial disposals, units-of-use depreciation, or multi-book registers
- You want portfolio-level depreciation forecasting
- You have asset finance loans (hire purchase) to account for
- You operate across multiple entities and need consolidated reporting
Conclusion
For straightforward fixed asset accounting, Xero does what it says. For New Zealand organisations with NZ IFRS obligations, larger asset registers, lease accounting requirements, or the need for pre-loaded IRD rate content, the built-in module has real limitations — and those limitations are well documented.
AssetAccountant is designed for organisations in this position. It handles the fixed asset, tax depreciation, and lease accounting requirements that specialist NZ clients need, and it continues to work directly with Xero as the underlying accounting system.
