may not getting full ev credit....what other options?

Status : MFJ, no kid

Annual salary : approx. $93500 (sole income for us)

IRS tool estimated fed income tax approx. 5300.

Twice a month, I put approx. $230 for Fed income tax withhold and $240 for SS tax withhold. (no state income tax)

And there will be approx. $12000 for 401k

 

At this rate, it seems like I wouldn't be able to get full ev tax credit, but anyone can confirm?

Some says to work with professional to increase tax liability but how and what's benefit for paying more taxes???
