The headphones I bought on 28 August went back to the shop on 9 September. The refund appeared on my card on the 11th. My tracker had three opinions about that AED 1,200: it was income, it belonged in a category called Refunds, and September was now my cheapest month of the year. All three were wrong, and I have seen the same three mistakes made by people with accounting degrees. The fix is a rule I borrowed from work.
Is a refund income or a negative expense?
Neither word is quite right, but negative expense is the one that keeps the reports honest. The money coming back is not something I earned. It is the purchase being undone. If it goes into income, two numbers break at once: earned-this-month goes up by AED 1,200 that nobody paid me, and Electronics still shows a AED 1,200 purchase that no longer exists.
At the trading company where I work, this is not a matter of taste; the VAT law settles it. A return is one of the listed reasons a supplier must adjust output tax: Article 61 of the VAT Decree-Law names the case where the customer “returned them to the Registrant in full or in part and the Consideration was returned in full or in part”. The supplier then issues a tax credit note, defined in Article 1 as “a written or electronic document in which the occurrence of any amendment to a Taxable Supply that reduces or cancels the same is recorded”. Article 62 gives them 14 days to issue it. Nobody in the finance team books a credit note as a sale. It is filed against the invoice it reverses, and it reduces purchases in the same expense line the invoice sat in.
A refund carries the category of the purchase it undoes. If the purchase was Electronics, the refund is Electronics with a minus sign.
The personal version is the same discipline with less paperwork: whatever your tracker calls money coming into a card, the category on that line is the category of the original purchase. A Refunds category is a bucket of unmatched credit notes, which is the messiest thing on any supplier statement I have ever reconciled.
Which month does a refund belong to?
The month it lands in. The purchase was August. The refund is September. August stays overstated by AED 1,200 and September is understated by the same amount, and that is fine, because it is true: in August, the cash left.
This is also what the law does for businesses. Article 63 says the tax on a credit note is “a reduction of the Input Tax by the Recipient of Goods or Recipient of Services for the Tax Period during which the Tax Credit Note was received”. Received, not issued, and certainly not the period of the original invoice. A closed period stays closed. The accountant does not reopen August to make it prettier.
What that means in practice is that a single month’s category total is a rough number and always was. The number that self-corrects is the category over any window that contains both lines: Electronics for the quarter is right, Electronics for August is not. If a month looks impossibly cheap, the first thing I check is whether a refund landed in it. The second thing I check is whether the refund matched the purchase, because it often does not.
Why the refund line rarely equals the purchase line
Three reasons, and each one is a cost that belongs in the category, not in a rounding error.
Restocking and partial refunds. If the shop keeps 10% for opening the box, the refund is AED 1,080 against a AED 1,200 purchase. Electronics for the two months nets to AED 120, and AED 120 is exactly what those headphones cost me. The tracker is not wrong. The category has a small, honest number in it.
Cashback comes back too. Emirates Islamic’s Switch Cashback terms spell out what most cashback cards do quietly: a merchant refund “will offset the retail spends in the Calendar Month in which the refund or reversal transaction has been processed by the merchant in accordance to the category of spend and adjust the Cashback earnings for the same Calendar Month”. On that card, “other spends” earn 1%, so the August purchase earned AED 12 and the September refund takes AED 12 off September’s cashback. The bigger effect is the threshold. The same terms pay cashback only “for a minimum billed amount of AED 2,500 per calendar month”. On that wording, a AED 1,200 refund in a month where the card billed AED 3,400 leaves AED 2,200 of net spend, under the line. My reading is that the refund does not cost AED 12 that month; it costs the whole month’s cashback. Read the terms on your own card before assuming otherwise.
Foreign bookings refund at a different rate. Mashreq’s general card terms put it in one sentence: “The refund will be posted to the Card Account at the exchange rate received from the processing Bank.” The next sentence is the one that matters: the bank “assumes no liability for any loss arising due to foreign exchange rates fluctuations or conversions, independent of how close in time the refund is to the original transaction”. Emirates NBD’s key facts statement prices the outbound leg: a “1.99% currency conversion fee is charged to the Card Account for all transactions incurred outside UAE”, on top of the network’s own processing fee of “approximately 1.15%”, converted “on the date the amount was posted to the Card Account rather than the date the Card was used”.
Run a cancelled USD 500 hotel deposit through that. At the peg, USD 500 is AED 1,836.25. Add the network’s 1.15% and the posted amount is AED 1,857.37. Add the bank’s 1.99% and the card shows AED 1,894.33. The refund is USD 500 at whatever rate arrives that day; if it arrives at the peg, the credit is AED 1,836.25. The two lines are AED 58.08 apart. Neither document promises that the conversion fee follows the money back, and the Mashreq wording says the gap is mine regardless of timing. So the honest entry is not “Travel: 0”. It is “Travel: AED 58.08, hotel cancelled”. That was the price of changing my mind, and a category that shows zero for it is hiding a cost I actually paid.
The three-line rule I use
The whole method fits in three lines, which is the point of a workbench post.
- Same category as the purchase, minus sign. Never income, never Refunds.
- Same month it landed. Do not edit the purchase, do not move the refund back.
- Whatever does not come back is the cost. Restocking fee, lost cashback, conversion fee: it stays in the category with a note saying why.
When I import a card statement, the refund sits in the credits column next to the payments, which is right for the card balance and wrong for the category until I put it back where the purchase was. That is two minutes a month. The alternative is a September that looks like the cheapest month of the year, a Refunds category that nobody can explain, and an income total that includes AED 1,200 I was never paid.
