The 2nd $1,200 EIP arrived between the time we filed our original 2020 tax return and our 2020 amended return. Why our did our tax increase $1,200 on the amended return?

We had $0 tax liability on our original 2020 return. We then received the $1,200 EIP. The amended return still has $0 tax liability, but now we suddenly must pay $1,200.

Did you file for $1200 Recovery Rebate Credit on your 2020 return?  If so, it was reversed out on the Amended Return, since you already got Stimulus #2.

But do not amend if you have not yet received your original refund. The IRS may adjust for this themselves anyway. Or are you amending  for some other reason?

[fanfare]

if you claimed line 30 on your original return,

you don't say you got it on your amended return.

That will cost you $1,200.

your revised return must say you didn't get it.

Sheesh.
