Which one is correct in using inversion?

[^^vangiang^^]

Someone can ask me which of these sentences uses inversion correctly ?
"Under no circumstance is the money paid" or "Under no circumstance is the money to be paid"

Thanks in advance

"Under no circumstance is the money to be paid"

thank you, Milanya .
However, i'm greateful if you can explain your choice more clearly
Thanks

"To be paid" indicated future. Money is not paid and should not be paid under any circumstances. Stands to reason.
"Is paid" indicates past. If money is paid already, you cannot make a condition about not paying. It is already done.
