The now common and still growing phenomenon of peer-to-peer goods exchange sites such as Gumtree or Facebook groups can throw up some interesting scenarios regarding the acquisition of claimable assets and the consequent work-related or business expense deduction claims.

In the case of Gumtree, for example, the online buy-and-sell site has enjoyed increasing usage since it launched in 2007, and has seen a huge expansion of the range of items listed on its pages beyond the proverbial spare bookcase or cheap bicycle.

As you may have already guessed, acquiring business assets through such sites can be not so much an issue with the deductibility of work-related expenses, but rather what may or may not be accepted by the ATO in regard to substantiation.

The requirements, and the exceptions
The legislation provides that to deduct a work expense, a taxpayer needs to substantiate it (if more than $300) by getting “written evidence”. The relevant section of the legislation sets out the rules relating to written evidence, and provides that the taxpayer must get a document from the supplier that sets out the:

1. name or business name of the supplier
2. amount of the expense
3. nature of the goods or services
4. day the expense was incurred; and
5. day it is made out.

There are two exceptions that the ATO typically allows:

• If the document does not show the day the expense was incurred, the taxpayer may use a bank statement or other reasonable independent evidence that shows when it was paid.

• If the document does not specify the nature of the goods or services, the taxpayer may write in the missing details before lodging their tax return.

There is also further leeway in that the ATO has the discretion to still allow a deduction, if the somewhat stringent conditions listed above are not met, if the nature and quality of evidence available satisfies it that a work expense was incurred and a valid deduction should be allowed. This could include, for example, bank statements, credit card statements, photographs or photocopies of a product or service offered at a particular price (see more details in this practice statement).

The problems with peer-to-peer transactions
But let’s get back to the scenarios that could arise with buying assets through the peer-to-peer website Gumtree.

It’s not hard to imagine that there may be many instances where a buyer agrees to meet a seller at a neutral location such as the local shopping centre (and it’s not uncommon for this to happen, to maintain privacy and/or security) and, given that the transaction is face-to-face and most likely conducted by cash, for none of the expected documentation (from a tax point of view) to exchange hands.

And this is not an unusual situation. In many if not most cases, these sellers could be just private citizens getting rid of clutter around their homes, and they are not running a business of selling these items. They therefore will have little interest in drawing up “formal” documents or perhaps even be unwilling to disclose all their personal details to a stranger. Mostly they’ll be focused on that cash in the buyer’s hand.

For business transactions (the most likely to seek a deduction for such an expense), a taxpayer with an enterprise, or commencing one, may use one of several platforms to buy an asset for work purposes — such as Gumtree, Trading Post or a Facebook Buy-Swap-Sell group for the local area. A taxpayer may also use a platform such as Airtasker to engage someone for a one-off business activity, or perhaps even rent some premises through Airbnb for a few days for business purposes.

For example, imagine a business operator using one of these platforms to:

• purchase a second hand domestic lawnmower to commence a gardening business
• purchase a second hand car in good condition to earn money from driving for Uber
• rent a holiday property to host a weekend yoga retreat
• purchase second hand furniture to furnish a home office.

Many vendors on these platforms are not running businesses. They may be individuals who, in their private capacity, wish to sell things they no longer need (like the lawnmower), make some money from renting an unused property on Airbnb, or earn income in their spare time by performing specific tasks (for example someone may advertise on Airtasker than they can assemble flat-packed furniture).

Of course with these online platforms there is always the possibility of keeping tabs of the electronic trail.

Is there a solution?
How then can the purchaser ensure that they can substantiate their purchase? Here are a few suggestions that may help the ATO use its discretion to allow a claim. For example:

• draw up the document for the vendor and only ask that they sign it
• remember that the ATO can accept alternative evidence, so if the seller is unwilling to, say, provide their address, the purchaser and vendor could countersign a document specifying that the transaction took place at a specific location, day and time
• if the sale takes place in public, evidence from a related transaction may assist (perhaps a receipt for a coffee or snack bought at the date, time and place of the sale)
• photographic evidence of the exchange of goods and money
• withdraw the exact amount involved in the transaction from the bank near the time of the transaction so that there is a record on a bank statement
• keep a screenshot of the relevant internet advertisement (this is important as most ads are deleted once an item is sold). While this will not conclusively prove that the transaction took place, at least it shows that the item was really offered by the specified vendor at that price in the relevant timeframe.
• keep a record (again, perhaps screenshots, or even print-outs) of messages between purchaser and vendor —such as arranging the meeting time and place, negotiating the purchase of the item, and so forth.

The trouble for many of course is that claims are generally sought to be made after the transaction has occurred. However keeping the above points in mind could be helpful for future legitimate deductions.
