Hi, Barbara.
Most of your questions have already been tackled by the other posters. I'd like to focus on just the accrued interest purchased.
Except for bonds purchased within the past year, that purchased interest should have been forgotten by now. In your example, the $87.05 that your parents paid out for accrued interest would have been returned to them as a part of their first interest income check. On a typical bond that pays interest semi-annually, the $87.05 would have reduced their income for the year of purchase or the following year, depending on the timing of their purchase.
Accrued interest purchased is not an expense, exactly; it is a reduction of income. If the first interest income is in the same year as the purchase, it is obvious that only the net amount is income. If that first interest is not received until the following year, the proper treatment is the same, but it is not so obvious.
Suppose you buy a $5,000 bond paying 6%, with $150 checks paid semi-annually on March 1 and September 1. If you buy the bond on July 1, you will have to also buy the $100 interest accrued since the last March 1. On September 1, you will receive $150, representing the $100 you bought plus $50 accrued from July 1 to September 1. Your income for that year will be only $50, although you actually received $150.
If you bought that same bond on November 1, 2005, you would have to pay $50 for the interest accrued since September 1. You will not receive any interest check until March 1, 2006, when you will get $150, representing the $50 you paid plus $100 accrued since your purchase. For 2005, you will report no income. You also will not be allowed to deduct the $50 you paid for the accrued interest you bought. You must remember that Accrued Interest Purchased and carry it over to 2006, when you receive the first interest income, which includes what you purchased.
For current bond purchases, you can handle accrued interest purchases in the theoretically correct way, or in the more practical way, especially if there are only a few of them. The correct way is to use an Asset Account called Accrued Interest Receivable. When you buy the bond, put the principal in Bonds and the purchased interest in this separate account. When you receive the first interest check, reduce this purchased interest account to zero and put only the excess in the Interest Income Category. With this method, your Income Statement will always show only the interest you've earned, not what you've purchased, and your Balance Sheet will show the interest you've purchased as a part of your net worth.
The more practical handling, for most people, is to just put the purchased interest into the Interest Income Category as a debit (a "negative income" amount). When the first interest check arrives, put it into this category as usual. The plus and minus amounts will result in your correct net income for the year. But if your year ends before the first interest check is received, then you must remember to NOT deduct purchased interest for THIS bond this year. You'll have to remember to deduct it from next year's interest receipts. And you can't use interest purchased with Bond A to offset interest received on Bond B.
In your parents' situation, most of those bonds were purchased more than a year ago. The first interest check on each of them was received - and reported - in prior years. For those bonds, the interest purchased is no longer relevant and need not be recorded at all now. Even for bonds purchased last year, if the first interest receipt was in the prior year, the purchased interest is not relevant now. But for bonds on which the first interest has not been received, you should record the purchased interest as either Accrued Interest Receivable or as a minus in income, to offset that first interest check when it is received.
Since these are all municipal bonds and, presumably, the interest has always been excludable from your parents' taxable income, it might not matter if the accrued interest was not reported properly in the past. But if the amounts are significant, you might want to review prior years' returns to see if any of them need to be amended. Were those returns prepared by a CPA or other competent tax professional?
Since the bond in your example was purchased at a discount, you have a further issue of the amortization of the discount, but let's leave that complex subject for another day. The $2.35 fee should be included in the tax "basis" of the bond.
