Thank you for that, glitch99. I was unaware and your post is very helpful. So if I understand you correctly, related to the I bond scheme under discussion here:
If I overpay to snag my $5k in I bonds, and if I “over-overpay” to be certain of having at least $5K available to buy my I bonds, then:
If I’m reading you right there will be interest paid on my “over-overpayment” for the return of which I might have to wait a long time (refer to @scripta’s dilemma posted elsewhere on this forum). If they (the IRS) pay me interest it makes the wait a bit less burdensome and bothersome.
Thanks again for posting. I was unaware of the interest.
