Several states offer tax amnesty programs. Usually these are opportunities to pay taxes without interest or penalties as long as the payment is voluntary and before a certain deadline.
The IRS does not offer an amnesty program. The IRS has a policy of typically not criminally prosecuting taxpayers who voluntarily report past due tax liability, but they offer no guarantee of avoiding criminal prosecution. In any event, the IRS will always seek full payment of taxes, penalties, and interest.
It is usually not a good idea to wait for a state amnesty program to start because the IRS interest and penalties continue to mount.
People are selling on the internet How-to-Get-Amnesty programs for IRS taxes, but what they are really selling is either hype or just normal tax advice repackaged to make is sound better than it really is.
