Does it make sense to request Installment Plan before submitting an Offer in Compromise?

Hi,

 

I have insane tax bill for 2021 and am preparing an OIC.  Since an OIC takes a while to review, I am trying to get an installment plan in place so that the monthly penalty is lower.  So I filled out a 9465, since when I try to do it online it doesn't allow me, since my proposed monthly amount does not pay the bill in 72 months.

 

Does it make sense to do it this way?

 

thanks,

Brian
