How do you handle the accrued interest that you paid to purchase a CD on the secondary market? Do I include this cost as part of the cost of the cd (adjusting the capital gains basis)? Or do I adjust down the 1099 Int which shows all the interest payments for the year that include that amount. Example: I bought a cd for $1050, including $50 accrued interest. It matured later in the same year and I received the $1000 back plus $200 interest for the year which included the $50 that I had paid. I only made $150 off the CD. I should not have to pay $200 I never received.
