Fixed Asset Accounting (Anlagenbuchhaltung)

Fixed asset accounting, in German Anlagenbuchhaltung, is the sub-ledger that records an organisation's long-lived assets — buildings, machinery, vehicles, IT equipment — and tracks their value over time. It maintains the asset register, calculates depreciation, and posts acquisitions, transfers and disposals back to the general ledger. In a DACH context it must reconcile the differing valuation rules of commercial law (HGB) and tax law, and frequently a third set of values under IFRS for group reporting. Within an ERP system it is a standard finance module that feeds the balance sheet and supports the audit trail required for compliant bookkeeping.

What the module manages

Fixed asset accounting centres on the asset register and the lifecycle of each asset. Core functions are:

• Asset master data — one record per asset with acquisition date, cost, useful life and cost-centre assignment.
• Depreciation — periodic write-down of an asset's value over its useful life, using methods such as straight-line or declining balance.
• Acquisitions and additions — capitalising purchases and subsequent investments.
• Transfers and disposals — moving assets between cost centres and recording sales, scrapping or write-offs.

Each of these generates postings that flow into the general ledger, keeping the sub-ledger and the financial statements in agreement.

Multiple valuation views

A defining feature in the German-speaking market is parallel valuation. The same asset is often carried at different values for commercial-law reporting under HGB, for tax purposes, and for group accounts under IFRS, because the rules on useful life and permitted depreciation methods differ. Fixed asset accounting maintains these as separate depreciation areas on one asset master, so a single physical machine can show three book values. This is the practical face of the IFRS versus HGB distinction at asset level, and it is a key reason the module is more than a simple register.

Place in ERP financials

Fixed asset accounting is one of the finance sub-ledgers, alongside accounts payable and accounts receivable. Asset acquisitions usually originate as supplier invoices in payables and are then capitalised into the asset register; depreciation runs post automatically to cost-centre accounting, allocating expense to the responsible department. The module therefore sits at the intersection of procurement, controlling and statutory reporting, and its figures feed the record-to-report cycle.

Compliance and audit

Because asset values affect the balance sheet and the tax base, fixed asset accounting must be auditable. In Germany this means postings and the asset history have to satisfy GoBD requirements for traceability and an unbroken audit trail, and records must remain available for the statutory retention period. Common practice is to run periodic depreciation as a controlled, logged batch and to reconcile the asset register against the general ledger at each period close, so that every reported asset value can be traced back to its acquisition document.
