Got your car log book ready?

When claiming for work-related car expenses, many taxpayers miss out on maximising their claim due to inadequate record keeping. But also, failing to maintain a valid car log book can cost taxpayers dearly in a Tax Office audit.

The car log book is an important piece of tax substantiation for those who use their vehicle in the course of performing their duties. Most will be familiar with the two main instances where a car log book is required.

These include:

-where the individual is claiming a deduction in their personal tax return for work-related car expenses using the log book method, or

-where the individual is claiming a deduction in their personal tax return for work-related car expenses using the log book method, orwhere the individual or their associate has been provided with a car by their employer and is required to maintain a log for fringe benefit tax (FBT) purposes.

-where the individual or their associate has been provided with a car by their employer and is required to maintain a log for fringe benefit tax (FBT) purposes.

Why is a “good” log book important?

Over the last several years, the Tax Office has undertaken a motor vehicle registry data matching program to assess the overall taxation compliance of individuals and businesses involved in buying and selling motor vehicles.

The program involves the Tax Office requesting details from the state and territory motor vehicle registering authorities where

a vehicle has been transferred or newly registered and the purchase price or market value is equal to or exceeds $10,000.

FBT compliance under scrutiny

The initial appeal to some family businesses in acquiring a car through a company or trust is understandable. These entities

are generally entitled to claim input tax credits under the GST regime, with the maximum credit capped at $5,224 for the GST inclusive cost of cars that exceed the current car limit of $57,466.

Notwithstanding this immediate cash flow benefit, the sting in the tail is that some businesses may not be fully aware of their FBT obligations and may be liable to FBT. Through its data matching process, the Tax Office has identified poor FBT compliance by family businesses that provide newly acquired vehicles to the business owner or their family members.

Changes to car expense claims make log books critical

The government recently changed the way that individuals claim their work-related car expenses, which applies from July 1, 2015.

These changes include:

-the cents per kilometre method will use a standard rate of 66 cents per kilometre rather than a rate based on the engine size of the car, and

-the one-third of actual expenses method and the 12% of original value method has been abolished because the Tax Office found that only 2% of taxpayers used these methods.

With the above changes, greater emphasis will be placed on individuals who travel  more than 5,000 business kilometres to maintain a valid log book, if they opt for the log book method.

The log book method will therefore benefit an individual if their estimated deduction exceeds $3,300 for the 2015-16 income year (that is, 66 cents x 5,000 kms under the cents per kilometre method). The log book method does however require receipts and a log book to be kept. For some, this may require some diligence!

There’s an app for that

The Tax Office’s smartphone app containing the myDeductions tool may solve the record keeping dilemma, as it enables the individual to capture receipts for work- related car expenses as well as to enter information for a log book.

Although the tool is appropriate for individuals wishing to claim work-related car expenses, the Tax Office has not indicated whether it is appropriate for FBT purposes. In any case, there are other third party apps that may satisfy the

requirements under FBT law. Users should satisfy themselves that such apps fulfil the requirements under the tax law (and check with us if you’re not sure).

What are the requirements for a valid log book?

The purpose of the log book and accompanying odometer records is to determine the business use percentage of the vehicle.

As a general rule, the higher the business- use percentage:

-under income tax — the greater the deductions that may be claimed for work-related car expenses

-under FBT — the lesser the amount of FBT payable for car benefits.

The requirements for maintaining a log book for income tax and FBT purposes are mostly identical, although there are some small differences. The main one is that an FBT log book applies to the relevant FBT year (that is, ending March 31) while an income tax log book applies naturally to an income year (that is, ending June 30).

Things to be mindful of when using a log book include:

-the log book is valid for five years – after the fifth year, a new log book will need to kept. A new one can be started at any time (for example, if it no longer reflects the business use)

-the log book must be kept for at least a continuous 12 week period – note  that the year in which the log book is first kept is referred to as the “log book year”; otherwise it is referred to as a “non-log book year”

-for two or more cars – for income tax, the log book for each car must cover the same period. For FBT, one log book must be maintained for each car where multiple cars are provided by an employer.

-the log book must reflect the business use of the vehicle – this can be tricky where there is home to work travel, travel between workplaces, or if the individual’s work is itinerant in nature

-odometer records must also be kept– this is crucial for working out the total distance travelled during the year and also for the relevant period that the log book is kept.
