Vehicle Asset Register in Xero – How to Record, Depreciate and Manage a Company Car

If your business buys a car, simply paying for it from the bank account is not enough for accounting and tax purposes.

The car becomes a business asset, which means it needs to be recorded properly in your asset register, depreciated over time, and if financed, the loan needs to be split correctly between liability and interest.

This guide explains, in simple words, how to record a company vehicle in Xero, using a real example.

Example

Your company buys a vehicle for $85,000 (including GST).

The car is purchased under finance.

You want to know:

• How much GST can be claimed?

• How to record the asset in Xero?

• How depreciation works

• How loan repayments are treated

• What journals are needed

• What liability account to use

Let’s break it down.

Step 1: Work Out the GST Claim

In Australia, for passenger vehicles there is a car limit for depreciation and GST claims.

The ATO only allows GST credits up to the car limit, even if the car costs more.

For the 2025–26 financial year, the car limit is approximately $69,674 (excluding GST).

That means the maximum GST claim is:

$69,674 × 10% = $6,967

So even though your invoice shows:

Purchase Price: $85,000
GST included: $7,727

You cannot claim all $7,727.

You can only claim approximately:

Claimable GST = $6,967

The remaining GST becomes part of the asset cost.

This means your depreciable asset value will usually be adjusted.

This is one of the biggest mistakes businesses make when entering expensive cars into Xero.

Step 2: Create the Fixed Asset in Xero

Go to:

Accounting → Fixed Assets → Add Asset

Enter:

Asset Name: Company Vehicle – Toyota Prado
Asset Type: Motor Vehicles
Purchase Date: Date on invoice
Cost: Adjusted cost after GST cap rules
Depreciation Method: Diminishing Value (or Prime Cost depending on tax strategy)
Useful Life: Usually 8 years for accounting

Save the asset.

Xero will automatically include it in your asset register.

Step 3: Record the Purchase Journal

If financed, do not expense the purchase.

Post:

Debit: Motor Vehicle Asset → $78,033
Debit: GST Receivable → $6,967
Credit: Vehicle Loan Liability → $85,000

This records:

• The business owns the asset

• GST claimable from ATO

• Loan payable to lender

Step 4: Set Up the Loan Liability Account

Create a liability account:

Vehicle Finance Loan

Type:

Non-current liability

This account tracks how much is still owed.

Every repayment reduces this balance.

Step 5: Record Loan Repayments Correctly

Example monthly repayment:

$1,800

The lender statement shows:

• Principal: $1,300

• Interest: $500

Journal:

Debit: Vehicle Loan Liability → $1,300
Debit: Interest Expense → $500
Credit: Bank → $1,800

Important:

The principal is not an expense.

Only the interest is deductible.

A lot of businesses accidentally code the full repayment to motor vehicle expense, which overstates deductions.

Step 6: Depreciate the Vehicle

At year-end, Xero calculates depreciation.

Example annual depreciation:

$9,754

Journal:

Debit: Depreciation Expense → $9,754
Credit: Accumulated Depreciation → $9,754

This reduces profit gradually over the life of the car.

The vehicle stays on the balance sheet while depreciation reduces its carrying value.

Step 7: Keep a Logbook

If the vehicle is used partly for personal travel, you need a valid logbook.

This determines the business-use percentage.

Example:

Business use = 80%

Then:

• 80% of running costs deductible

• 80% of GST claimable (subject to car limit)

• FBT may apply if available for private use

Without a proper logbook, ATO adjustments can become expensive.

Common Xero Mistakes We See

Businesses often:

❌ Expense the full car purchase
❌ Claim full GST above the cap
❌ Record full loan repayment as expense
❌ Forget depreciation journals
❌ Ignore private use adjustments
❌ Miss FBT obligations

These mistakes can create major issues during tax lodgement or an ATO review.

Expert Tip from PW Tax

When recording company vehicles, always check:

✔ Car limit rules
✔ GST cap rules
✔ Finance split
✔ Depreciation method
✔ Business-use percentage
✔ FBT exposure

Getting this right from day one saves time, tax adjustments, and accountant cleanup fees later.
