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.
