CBDT - Due date extended for Tax Audit Cases

Kindly upload notification.

CBDT extends due date for filing of Income Tax Returns & audit reports from 30th Sept, 2018 to15th Oct, 2018 for all assessees liable to file ITRs for AY 2018-19 by 30.09.2018, after considering representations from stakeholders. Liability to pay interest u/s 234A of IT Act will remain.

"Liability to pay interest u/s234A of ITAct will remain" what does this line mean- do we need to pay tax till 30th september or not?
