A fixed asset audit answers a deceptively simple question: do the assets on the books actually exist, and is everything that physically exists recorded? Getting that answer right protects the balance sheet from ghost assets, supports a clean audit opinion, and underpins accurate depreciation and tax. This guide walks through how to audit fixed assets step by step, organized around the audit assertions that auditors are ultimately trying to satisfy.
How do you audit fixed assets?
Obtain the fixed asset register, reconcile it to the general ledger, then verify assets two-directionally: trace recorded items to the floor to confirm existence and trace floor assets back to the register to confirm completeness. Then test additions and disposals, recalculate depreciation, and document every exception.
What Is a Fixed Asset Audit?
A fixed asset audit is the systematic verification that the long-lived assets recorded in an organization's books — property, plant, and equipment (PP&E) — actually exist, are owned by the entity, are in the stated location and condition, and are valued and depreciated correctly. It reconciles the fixed asset register to the general ledger and to physical reality, closing the gap that produces ghost assets, unrecorded assets, and depreciation misstatements.
The audit can be a discrete exercise run by internal audit or an independent specialist, or it can be the fixed asset portion of the annual financial-statement audit. In every case, the work is organized around a set of standard audit assertions for PP&E — existence, completeness, rights and obligations, and valuation/accuracy — which the procedures below are designed to satisfy.
Why Audit Fixed Assets?
Fixed assets are often one of the largest line items on the balance sheet, yet they move, get retired, and get replaced far from the accounting team's line of sight. Auditing them matters for several concrete reasons:
- Ghost assets: Assets recorded in the register but no longer present overstate net book value and inflate depreciation expense. They also drive unnecessary property tax and insurance premiums.
- SOX compliance: For public companies, fixed assets are typically a significant account subject to internal control over financial reporting. Under Sarbanes-Oxley Section 404, management must assess, and the external auditor must test, the controls over existence and valuation of PP&E.
- Insurance: Accurate asset records support correct insured values and faster, better-supported claims after a loss.
- Mergers and acquisitions: Buyers and lenders rely on a verified asset base during due diligence; an unverified register invites valuation disputes and purchase-price adjustments.
The Fixed Asset Audit Process — Step by Step
Whether performed by internal audit, an external firm, or an independent specialist, a fixed asset audit follows the same seven-step process. Each step maps to one or more PP&E assertions.
Step 1: Plan & Scope
Define the asset population, materiality, sampling approach, locations, and cut-off date. Risk-rank asset classes so high-value, mobile, and high-turnover assets (IT equipment, vehicles, tools) receive fuller coverage than low-risk, immovable items. Decide whether the engagement calls for a full wall-to-wall verification or a risk-based sample, and agree on variance thresholds that will trigger investigation.
Step 2: Obtain the Fixed Asset Register
Extract the complete register from the ERP or fixed-asset subledger with, at minimum, acquisition cost, in-service date, location, custodian, asset class, useful life, accumulated depreciation, and net book value. Clean it before fieldwork: remove duplicates, fix invalid dates, and standardize locations. The register is the population the audit tests against, so its quality sets a ceiling on the audit's reliability.
Step 3: Physical Verification (Two-Directional)
Physical verification is the core procedure for the existence and completeness assertions. It confirms that each asset exists, is in the recorded location, and is in usable condition — and it must run in two directions:
- Sheet-to-floor: Select items from the register and confirm each physically exists on site. This tests existence and surfaces ghost assets — recorded items that are no longer there.
- Floor-to-sheet: Select physical assets observed on the floor and confirm each is recorded in the register. This tests completeness and surfaces unrecorded assets — items in use that never made it into the books.
Running a single direction is a common mistake: sheet-to-floor alone catches ghosts but misses unrecorded additions, while floor-to-sheet alone does the reverse. Scanning barcode or RFID tags during the count speeds fieldwork and creates a verifiable evidence trail; condition and location are captured at the same time.
Need a two-directional count your auditors will accept?
Existence and completeness assertions hinge on independent, documented physical verification. CPCON verifies, reconciles, and tags fixed assets against your ledger and delivers an audit-ready register — across 30+ countries, for 2,500+ organizations.
Step 4: Reconcile to the General Ledger
Tie the fixed asset subledger (the register) to the general ledger control accounts for cost and accumulated depreciation, and investigate every variance. Unreconciled differences between the subledger and the GL are one of the most common audit findings, and they often hide unrecorded disposals, double-booked additions, or posting errors. For the full mechanics, see our guide on how to reconcile fixed assets.
Step 5: Test Additions & Disposals
Select a sample of current-period additions and vouch them to supporting evidence — purchase orders, invoices, and receiving documents — to confirm they were properly capitalized, recorded at correct cost, and placed in service on the right date. Select a sample of disposals and confirm they were authorized, removed from the register, and that the resulting gain or loss was calculated correctly. The biggest risk here is the unrecorded disposal: an asset physically retired or sold but still sitting on the books, which is precisely what physical verification helps catch.
Step 6: Assess Depreciation & Impairment
Recalculate depreciation for a sample of assets to confirm the method, useful life, and salvage value match policy and are applied consistently. Check that fully depreciated assets still in use are flagged and that newly added assets begin depreciating in the correct period. Then evaluate impairment indicators — idle, obsolete, or damaged assets — and confirm any required write-downs have been recorded. Note that non-depreciable assets such as land are verified for existence and ownership but assessed for impairment rather than depreciation.
Step 7: Document Findings & Report
Compile the evidence, exceptions, and recommended adjustments into a fixed asset audit report. Quantify the ghost assets, unrecorded assets, reclassifications, and depreciation corrections identified, and deliver an updated, reconciled register alongside the report. Good documentation is what lets a reviewer — or an external auditor — trace any conclusion back to its supporting evidence.
Key Audit Assertions for PP&E
Every procedure above exists to satisfy one or more audit assertions — the implicit claims management makes about the fixed asset balances. For property, plant, and equipment, the assertions that matter most are:
| Assertion | What it claims | Primary procedure |
|---|---|---|
| Existence | Recorded assets actually exist at the reporting date. | Sheet-to-floor physical verification. |
| Completeness | All assets that should be recorded are recorded. | Floor-to-sheet physical verification. |
| Rights & obligations | The entity owns or controls the recorded assets. | Inspect invoices, titles, deeds, and lease terms. |
| Valuation & accuracy | Assets are recorded at correct cost, net of proper depreciation and impairment. | Recalculate depreciation; test cost and impairment. |
Common Findings
Across fixed asset audits, the same exceptions recur. Knowing them in advance lets you target procedures and remediate before the external auditor arrives:
- Ghost assets: Items still on the register that no longer exist — usually because a disposal, loss, or theft was never recorded. They overstate net book value and depreciation. Sheet-to-floor testing is the detection procedure.
- Zombie assets: Assets that are fully depreciated to zero or near-zero book value yet remain in active use. They carry no remaining value on the books but represent real, productive capacity, distorting both asset registers and capital-planning decisions.
- Unrecorded disposals: Assets physically retired, scrapped, or sold but never removed from the register, leaving phantom cost and accumulated depreciation on the ledger. Tying floor results back to the register and reviewing the disposal log surfaces them.
Each finding is documented, quantified, and resolved with a supporting adjustment so the corrected register ties cleanly to the general ledger.
How CPCON Helps
CPCON performs independent fixed-asset verification end to end — register extraction, two-directional physical verification with RFID and barcode scanning, asset tagging, GL reconciliation, and exception resolution — and hands your external auditors a clean, audit-ready register. Because the verification is independent and fully documented, it strengthens the existence and completeness evidence auditors weight most heavily. Teams preparing for a year-end audit often start with our fixed asset audit preparation guide and work the field with our fixed asset verification checklist.
Frequently Asked Questions
What is the fixed asset audit process?
The fixed asset audit process is a structured set of procedures that confirms recorded property, plant, and equipment exists, is owned, and is valued correctly. It runs through seven phases: plan and scope, obtain the fixed asset register, perform physical verification, reconcile to the general ledger, test additions and disposals, assess depreciation and impairment, and document findings in an audit report.
How do you audit fixed assets?
Obtain the fixed asset register, reconcile it to the general ledger, and verify assets two-directionally: trace recorded items to the floor to test existence, and trace floor assets back to the register to test completeness. Then test additions and disposals, recalculate depreciation, assess impairment, and document every exception in an audit report.
What is two-directional fixed asset testing?
Two-directional testing verifies fixed assets in both directions. Sheet-to-floor testing selects items from the register and confirms each physically exists, testing the existence assertion. Floor-to-sheet testing selects physical assets on site and confirms each is recorded, testing completeness. Running both directions catches ghost assets and unrecorded assets that a single direction would miss.
What are ghost assets?
Ghost assets are items still recorded in the register and on the balance sheet that no longer physically exist or are no longer in use — typically because a disposal, loss, or theft was never recorded. They overstate asset values, inflate depreciation, and can increase property tax and insurance costs. Sheet-to-floor physical verification is the primary procedure used to detect them.
Who should perform a fixed asset audit?
A fixed asset audit can be performed by an internal audit or finance team, by external financial-statement auditors as part of the annual audit, or by an independent fixed asset verification specialist engaged for the physical count, reconciliation, and tagging. Many organizations use an independent specialist for the fieldwork-heavy verification because independence strengthens the existence and completeness evidence external auditors must test.
