How can I fix this select without using subquery?

Question

Hi guys is there any way to do the where below (in bold) without using an aggregate query before?
select
SUM(NET_AMOUNT)
as net,
SUM(TAX_AMOUNT)
as tax,
SUM(NET_AMOUNT)+
SUM(TAX_AMOUNT)
as total from ledger left join alloc on ledger.trxid=alloc.trxid where
 (SUM(NET_AMOUNT)+
SUM(TAX_AMOUNT))
> allocated
net and tax are in the ledger and allocated is in the alloc table. Sometimes the total of the amount (net+tax) is greater than the allocated so I need to retrieve all the rows where allocated is null or  tot is greater than allocated.
It's possible without CTE?
Thanks

Resolved.
SUM(NET_AMOUNT)
as net,
SUM(TAX_AMOUNT)
as tax,
SUM(NET_AMOUNT)+
SUM(TAX_AMOUNT)
as total from ledger left join alloc on ledger.trxid=alloc.trxid ....group by....
having ((SUM(NET_AMOUNT)+
SUM(TAX_AMOUNT))
> allocated)
Sometimes I need to post the issue in the forum just to remember how do the things.
Thanks and sorry
