Why does the debt sometimes decrease?
The Public Debt Outstanding decreases when there are more redemptions of Treasury securities than there are issues.
How do you make a contribution to reduce the debt?
There are two ways for you to make a contribution to reduce the debt:
You can make a contribution online either by credit card, checking or savings account at Pay.gov
You can write a check payable to the Bureau of the Fiscal Service, and in the memo section, notate that it's a Gift to reduce the Debt Held by the Public. Mail your check to:
Attn Dept G
Bureau of the Fiscal Service
