Buying a Bond Between Coupon Dates Requires an Accrued-Interest Reconciliation

Separate the bond price from purchased interest

An owner buying a bond between its interest payment dates may pay the seller for interest that accrued before the purchase. The next coupon can then include both interest earned during the owner’s holding period and recovery of the interest amount paid to the seller. The Schedule B instructions describe a separate accrued-interest adjustment when the purchaser’s information return includes that amount. Treating the entire coupon as the purchaser’s own earnings can overstate income.

Obtain the settlement statement rather than relying on the amount withdrawn from the account. It should distinguish the security price, accrued interest, fees, and total settlement cash. Purchased accrued interest is a different issue from bond premium, original issue discount, or market discount. A transaction can involve more than one of those items, and coding every difference from face amount as accrued interest would not provide a defensible tax result.

Follow the first coupon through a numerical example

Assume an individual purchases a conventional taxable bond for a separately quoted security price of $50,000 and pays $600 of accrued interest to the seller. There are no transaction fees, premium, discount, or other adjustments. The total cash paid is $50,600. The buyer later receives a $1,500 coupon, of which the documented $600 represents the interest purchased at settlement.

On these simplified facts, the buyer’s own interest income from that coupon is $900, calculated as $1,500 less $600. If an information return reports the full $1,500, the buyer should reconcile the supported accrued-interest adjustment under the applicable reporting instructions. At an assumed 32% federal marginal rate, simplified tax on the buyer’s $900 income is $288 rather than $480 on the entire coupon.

The $192 difference in that example is not a deduction for losing money on the bond. It reflects that part of the coupon recovers a separately purchased interest entitlement. The owner’s economic cash flow is a $50,600 settlement outflow followed by a $1,500 receipt. Showing a $1,500 investment yield without recognizing the purchased $600 can distort both the tax forecast and the performance comparison with another reserve investment.

Reconcile information returns without double adjustment

Review how the broker reports the coupon and whether an adjustment has already been incorporated. If the reported taxable interest is already reduced appropriately, do not subtract the same $600 again. Compare the tax statement, transaction detail, and return workpaper. The supporting schedule should show the gross coupon, purchased accrued interest, any other distinct adjustments, and the amount finally included as the buyer’s income.

The Schedule B instructions identify the adjustment as accrued interest rather than a nominee distribution, even though they describe a similar subtotal presentation. Follow the current instructions for the taxpayer’s return and preserve the reconciliation. Do not omit the payer’s information return from the preparation file because its gross amount is larger than the final taxable amount. A clearly documented difference is easier to review than a missing form.

Keep later basis and cash projections distinct

Maintain the bond’s separate tax basis schedule alongside the purchased-interest reconciliation. The $50,000 security price in this simple example is distinct from the $600 interest purchase. If a bond has premium, market discount, original issue discount, a defaulted coupon, a special instrument classification, or a later sale before the next coupon, additional rules may change the analysis. The simple example should not be used to assign every settlement component without reading the actual terms.

Record acquisition and coupon dates, interest period, seller accrual amount, custody account, security identifier, and the source of each calculation. Match the payment to the actual coupon schedule rather than assume a round fraction of a year. If multiple lots of the same bond were acquired on different dates, keep their purchased-interest amounts separately identifiable until they have been properly recovered and reported.

Before using the coupon to fund estimated taxes or an owner distribution, distinguish return of purchased interest from new income and from repayment of principal. The tax reserve should follow the supported $900 in the example, while the cash forecast still shows the entire $1,500 received. The concrete action is to require settlement-level accrued-interest detail for every between-coupon purchase and reconcile the first payment before finalizing the annual investment-income schedule.
