Your return has been rejected as ineligible for e-filing due to suspicious characteristics detected by the IRS system. The only solution is to paper file your return.
If you received IRS reject code R0000-198, it means your tax return has been deemed ineligible for e-filing. This rejection can occur at any point—whether during the initial submission, after fixing a prior reject, or when filing an amended return.
Why does this happen?
The IRS does not provide specific reasons for this rejection, only stating that the return contains suspicious characteristics based on their Modernized e-File (MeF) system.
How to resolve it?
Unfortunately, there is no way to e-file once this reject occurs. The only solution is to paper file your return.
