THE IRS TOTALLY IGNORED MY RESPONSE TO THEIR PREVIOUS CP-515. YOU KNOW, THE ONE WHERE I REQUESTED PROOF THAT I WAS REQUIRED TO FILE A 1040.

THEY NOW SENT ME A CP-518 NOTICE. IT'S BASICALLY THE SAME NOTICE BUT NOW THEY'RE NOT REQUESTING FOR MY TAX RETURN. THEY'RE TELLING ME THAT MY TAX RETURN IS OVERDUE AND I SHOULD PAY IN FULL ANY TAX DUE.....BLAH,........BLAH...BLAH...

IT'S AMAZING HOW THEY DIDN'T EVEN MENTION RECEIPT OF MY CERTIFIED RESPONSE LETTER TO THEIR CP-515.

ANY SUGGESTIONS ON HOW TO RESPONSE TO THIS CP-518?
