Section 245 compliance

Don't pay dues now. Let it gets adjusted against refund. The system may not credit the payment before adjustment, and it may happen that you may have to run pillar to post for refund of the dues amount paid at this stage.

Rightnow don't pay dues,, let it be adjusted from your refund .. however it would be good to know the exact demand outstanding.. because if your outstanding demand is correct then interst U/s 220(2) will also be charged after adjustment of refund...and that would be adjusted against your refund for subsequent years ..
