Mary J. Blige -- No More Drama in NJ ... Kisses Off $900K Debt

Mary J. Blige just pulled an Olivia Pope ... handling a huge chunk of her massive debt by erasing more than $900K worth of state taxes.

TMZ broke the story ... Blige was hit with a tax lien last February in New Jersey. Court records had her on the hook for $901,769.65 ... but new docs, obtained by TMZ, show the whole matter's been squared away.

That might feel great for Mary -- if not for the fact she still owes the Feds another $3.4 million for back income taxes.
