Form 8888Allocation of Refund (Including Savings Bond Purchases)

4a — Savings Bond Purchase Amount Updated for tax year 2025

Does this apply to you?

  • You want to use part of your tax refund to buy U.S. Series I Savings Bonds
  • You want paper I Bonds (this is the only remaining method to purchase them)
  • You are looking for a low-risk, inflation-protected place to park part of your refund

Easy to overlook

This is the only way to get paper I Bonds Since 2012, the IRS tax refund is the sole method for purchasing paper Series I Savings Bonds. All other I Bond purchases through TreasuryDirect are electronic. Filers who want physical paper bonds must use Form 8888 line 4a. The annual purchase limit for paper I Bonds through your refund is $5,000, separate from the $10,000 electronic limit. 1 Treasury Direct — Series I Savings Bonds purchase rules

The amount must be in $50 increments Your savings bond purchase amount must be at least $50 and must be a multiple of $50. If you enter $75 or $125, the IRS will not process the bond purchase. Round to the nearest $50 increment when deciding how much of your refund to allocate here. 2 IRS Form 8888 instructions — Part II, Line 4a

Watch out for this

Exceeding the $5,000 annual limit for paper I Bonds purchased through your tax refund. If line 4a plus line 5a exceeds $5,000, the IRS rejects the bond purchase portion and deposits the excess into the account listed on line 1. The $5,000 paper bond limit is separate from the $10,000 annual limit on electronic I Bond purchases through TreasuryDirect.
