Series I Bonds — Your Questions Answered – Kiplinger’s Personal Finance

Series I savings bonds are drawing a lot of attention. Thanks to high inflation, those issued from May through October 2022 offer a sky-high composite rate of 9.62%. We’ve compiled answers to frequently asked questions about series I bonds. 

How is the interest rate determined? The composite rate has two parts: a fixed rate, which remains the same for the life of the bond, and an inflation rate, which is based on the consumer price index.

If your bond has an October 2022 issue date, for example, interest is first posted in February 2023. 

How much can I buy? An individual can buy up to $10,000 per calendar year in electronic bonds through In addition, you can buy up to $5,000 each year in paper bonds with your tax refund (so for those who are married filing jointly, the limit is $5,000 per couple). 

How are I bonds taxed? I bond interest is free of state and local income tax, and you can defer federal tax until you file a tax return for the year you cash in the bond or it stops earning interest because it has reached final maturity (after 30 years), whichever comes first. You can also report the interest every year, which may be a smart choice if you’d rather avoid one large tax bill years down the road. If you use I …….
