Has COVID-19 impacted the validity of my logbook?

18 Nov, 2021


COVID-19 and car expenses

The impact of the COVID-19 pandemic on the economy has been far-reaching, and almost everyone’s work habits have been impacted in some way. Whether that is a change of schedule, updated responsibilities, or a change in work location. Many people are now taking client meetings via zoom, working from home, and are restricted in movements due to government-imposed lockdowns.

For many people, this may mean that there will be a decrease in car and travel expenses for the 2020–21 and potentially the 2021–22 income year. When claiming car and travel expenses using the logbook method, a taxpayer uses a representative period from the last five years as indicative of current use. But what does this mean for claiming car expenses for a period where the use of the car has changed due to changed work habits as a result of the COVID-19 pandemic?

Given the ATO’s extensive and ever-expanding compliance and data matching capabilities, incorrect car expense claims are more likely to be detected and disproved than ever before. Car and travel expense claims are a focus for the Commissioner year-on-year, and the Commissioner has already flagged that work-related expense claims will be targeted to ensure taxpayers aren’t copy and pasting claims from previous years, given the impact that the pandemic has had on many people’s day-to-day work habits.

The car expense deduction rules for individuals in Div 28 of the ITAA 1997 permit taxpayers to calculate deductions using one of two methods — the ‘cents per kilometre’ method and the ‘log book’ method. This article provides an overview of claiming car expenses using the log book method, and what to do if work habits have changed since the logbook was recorded.

Using the log book method

The rules for using the log book method are set out in Subdiv 28-F of the ITAA 1997.

A taxpayer can use the logbook method if they held, i.e. owned or leased, a car for some or all of the income year. The logbook provides a record of the car use for at least continuous 12 weeks, which will serve as a representative period of car travel for the income year. The records are then used to determine a business-use percentage, by comparing the proportion of business-related kilometres to total kilometres travelled (i.e. business-related travel plus travel of a private or domestic nature).

The percentage determined from the logbook can be used to claim a deduction for car expenses for up to five years, assuming that the percentage is still representative of the actual use of the car during that income period.

Definition — car expense
A ‘car expense’ is defined in s. 28-13.

When using the logbook method, a deduction for car expenses is worked out as follows:

While the substantiation requirements of using the log book are the most onerous of the methods available, if there is extensive business travel throughout the year, using the logbook method can be preferable because the amount that may be claimed is greater.

Working out the business use percentage

The business use percentage which the taxpayer can use is calculated under s. 28-90(3) as:

The number of business kilometres is based on a ‘reasonable estimate’. In making that reasonable estimate, the taxpayer must take into account all relevant matters including:

  1. any log books, odometer records or other records that the taxpayer has;
  2. any variations in the pattern of use of the car;
  3. any changes in the number of cars that the person used in the course of producing his or her assessable income.

Documentary evidence requirements

The substantiation requirements for the log book method are set out in Subdivs 28-G, 28-H and 28-I. They require that:

  1. all expenses must be substantiated using the rules in Subdiv 900-C;
  2. a log book must be kept in accordance with Subdiv 28-G (about keeping a log book);
  3. odometer records must be kept for the period when the car was held; and
  4. the following information must be recorded in writing before lodging the income tax return or such later period as the Commissioner allows:
    1.  an estimate of the number of business kilometres; and
    2. the business use percentage.
Rules about keeping the log book

The rules about keeping a log book are prescriptive:

  1. The log book must be kept for the first income year in which the log book method is being used for the car.
  2. The log book must cover a continuous period of at least 12 weeks throughout which the car is held. If the car is held for less than 12 weeks, the period must be the entire period for which the car was held.
    • The 12-week period can overlap the start or end of the income year, as long as it includes part of the year.
    • The log book method may be used for more than one car in the same year however the log books must cover concurrent periods of time.
    • Only business trips need to be recorded in the log book. These trips are recorded by making an entry in English specifying:
        • the day the journey began and the day it ended;
        • the car’s odometer readings at the start and end of the journey;
        • how many kilometres the car travelled on the journey; and
        • why the journey was made.
    • The record of a journey must be made at the end of the journey or as soon as possible afterwards .
    • Multiple journeys on the same day can be recorded as a single journey.
  1. The log book must also set out the following details:
  1. when the log book period begins and ends;
  2. the car’s odometer readings at the start and the end of the period;
  3. the total number of kilometres that the car travelled during the period;
  4. the number of kilometres that the car travelled, in the course of producing assessable income, on journeys recorded in the log book; and
  5. the number of kilometres referred to in (d) as a percentage of the total in (c).

Odometer records

Odometer records basically document the total number of kilometres the car travelled during a particular period. They also record the car’s engine capacity and other details.

Specifically, the records must state in English:

  • opening and closing odometer readings for the period; and
  • in the case of replacement vehicles, readings on the date the replacement took effect.

The records must be in English and made as soon as possible after the start or end of the period or the particular replacement day.

The records must also state:

  • the car’s make, model and registration number;
  • the engine capacity in cubic centimetres; and
  • the corresponding details for any replacement vehicles.

These records must be made prior to lodging the return or within such time as the Commissioner allows.

Retention of log book and odometer records

Log books must be retained for five years after the end of the latest year in which the person relied on the log book. The five-year period runs from the due date for lodging the return for the latest year or, if the taxpayer lodges late, from the actual date of lodgment. If the log book is not retained for the whole period, the claims made based on the log book can be disallowed.

Odometer records must be retained for the period in each year when the car is held. If a log book is retained, odometer records must be kept for the same period as the log book. The five-year retention period applies in the same way.

If the year of income is one during which a log book was not kept, the odometer records must be kept and retained for the same period as any written evidence of the expenses is kept for that year. This will also generally be for five years.

Substantiating car expenses

The general record-keeping provisions in Div 900 of the ITAA 1997 also apply. Subdivision 900-C (about substantiating car expenses) provides that for the log book method of deducting a car expense, the taxpayer must substantiate the expense by getting written evidence in accordance with Subdiv 900-E.

Getting written evidence — Subdiv 900-E

For expenses (other than the decline in value of a depreciating asset) a document must be obtained from the supplier and it must set out, in English or in the language of the country in which the expense was incurred:

Commissioner’s guidance

PS LA 2005/7 sets out the evidence that the Commissioner will generally accept for substantiating an individual’s claim for deductible work and car expenses (for non-business taxpayers).

Generally, a document or a combination of documents (such as invoices, receipts etc.) that contain the five items stated in s. 900-115(2) — see above — should be accepted as written evidence.

Records made and stored electronically are recognised as documents.

Where the above documents are insufficient, the Commissioner will accept the following documents (or combinations of documents) as evidence of expenses:

  • bank statements or credit card statements (hard copy or internet generated);
  • BPAY reference numbers (combined with bank statements or tax invoices);
  • internet generated receipts;
  • e-mail receipts;
  • paper copies of receipts; and
  • electronic receipts (or copies of receipts).

What do the COVID-19 restrictions mean for an existing logbook?

As outlined above, a log book provides a representative period of travel which is used to work out how much of a car expenses is deductible. If the pattern of car usage has changed after the log book was completed due to COVID-19 movement restrictions, does a new logbook need to be kept for an updated representative period of private and business usage during the COVID-19 pandemic? Not necessarily.

Under the law there are only two situations in which a taxpayer is legally obliged to keep a log book for an income year before the five-year expiry:

  • if the Commissioner sends the taxpayer a notice directing a log book to be kept; or
  • if the taxpayer acquires one or more additional cars for which they want to use the log book method.

However this does not mean that taxpayers should or could simply apply the business use percentage calculated using pre-pandemic logbook data. A log book is only one of the ‘relevant matters’ which the taxpayer is required to take into account in determining their reasonable estimate of the business kilometres travelled (see ‘Working out the business use percentage’ above). The taxpayer is obliged to consider the impact of work restrictions as well as any other relevant matter in conjunction with their log book.

However there is nothing to prevent a taxpayer from voluntarily creating a new log book. Indeed, in some cases this may be advantageous for the taxpayer to support a higher business use percentage where they could travel substantial distances as an authorised/permitted worker but private use of the vehicle decreased by comparison.

The ATO has provided the following guidance in its COVID-19 FAQ — Work-related car expenses:

Question: I claim my car-related expenses using the logbook method. Will I need to keep a new logbook for an updated representative period of private and business usage during COVID-19?

Answer: No, you are not required to keep a new logbook for the period in which your travel has been affected by COVID-19 as long as you account for any variation in the use of the car when working out your business kilometres and your business use percentage at the end of the income year.

When working out your business kilometres at the end of the income year, you need to make a reasonable estimate based on any logbooks, odometer records or other records you have.

In relation to the period in which your travel has been affected by COVID-19, you may keep a new logbook if you think it will provide a more accurate indication of your business use of the car. However if your overall business usage has not changed and you are merely using the car less, the odometer readings will reflect this and you will not need to keep another logbook.

A taxpayer may choose between the log book method and the cents per kilometre method per car on a year-by-year basis. Where the pattern of car usage changed substantially for an income year, the method which the taxpayer does not usually use may produce a better outcome.
