Hello. I am reposting this question.
My question is whether an erroneous store refund is taxable income. In two unrelated instances, I returned merchandise that I had purchased (for personal use, not for a business), and I received a refund for more than I had paid. The first time, I bought something on sale and when I returned it, the store mistakenly refunded me the full price. The second time, my refund was processed twice, so I received double what I should have. Is the extra money I received due to the stores' errors taxable income?
