My hunch is this might be worth a shot - but that also it might not be. Now I'm going to forensically examine this domain:
Extensions:
.net, .org, .biz, .us - never registered however .info was registered by someone in the past.
NameBio:
"Amount" at the end of the domain: 3 sales ever, however two of those are for the word paramount.
"Tax" 681 sales, obviously this includes "taxi" but a definite pass for this word.
Keywords:
to my surprise, this has a lot of exact searches:
1K – 10K
Low
€0.63
======
Overall, this might be worth a shot, however the poor performance of the word "amount" is a pity. However it's quite a professional domain. It's very matter of fact. There are a lot of small tax practitioners so pricing will be tricky - as in do you go long or short. That is your decision.
