Unclaim tax treaty for prior year

[someforeigner]

Hi everyone,

I am considering amending a prior year's return to unclaim a tax treaty. I was fully entitled to claiming it, but may consider reversing this for certain reasons, by amending and paying extra tax. Is there a problem with this -- e.g. might the IRS misunderstand this in some way?

Thank you!

not knowing what treaty we can't give you an answer. if the IRS allows the change you face penalties and interest for late payment.
