Can a Trust, which files a form 1041, use Form 8888 to request that part of the Trust's refund be used to purchase I-Bonds like an individual can?

Most likely not since trusts filing on Form 1041 are typically required to have an EIN.

not through form 8888

but you can directly

you'll see individual checked but below that  there is a section for Trust o Estate

Thanks.  I wonder if there is possible a different form to accomplish the same objective.  I know I can purchase I Bonds directly thru Treasury Direct (limit $10,000 annually), but was wondering about using a refund as you can on your personal return to acquire up to an additional $5,000.

There may be no harm in trying if you already have an account set up for the trust. 

I do not believe there is a parallel form to 8888.

Thanks.

Agree with tagteam. From Treasury Direct site regarding EIN:

"In a calendar year, one Social Security Number or one Employer Identification Number may buy:

• up to $10,000 in electronic I bonds, and
• up to $5,000 in paper I bonds (with your tax refund)"
