How is income tax calculated in relation to selling used items?
If the items you sold are items you previously bought for a higher price, the money you get selling them is not income, as you are taking a loss. However, you cannot deduct such losses. If you sell anything for more than what you paid for, the difference is a gain and is taxable.
