How Long Does It Take For Series EE Savings Bonds (dated 1986-1989) To Mature?

I believe they mature in 10 years  and govt. Pays you face value.   After 10 years, you don't have to redeem them, and insted you may keep them even longer, it's your choice. You may keep them up to 30 years maximum, so the payout will be even greater. After 30 years, the government. Pays no more interest and at that point you must redeem them by cashing them at  a bank, and the bank's responsibility is to report your interest earned on From 1099 INT. You are responsible to report the interest on your state income tax return only. The interest earned is not taxable on Form 1040 Federal. Only at state level. You must report it though, or face consequences. Going back a bit, you do not need to keep the bonds a full 10 years. They are redeemable after 6 months, I believe? You can keep them that short a time. Yours seem already old enough to cash in.  Ask a bank for sure.
