Belated fileing of returns for one day

Interest @ 1.5% per month or part of month.

Penalty - Rs 200  per day. (can be ignored)

Sir I haven't understood what to ignore 

Ignore interest @ 1.5% per month or

Rs 200 per day 

We can ignore penalty of Rs 200/-

Sir I want to know about the kvat is there any assessment called annual assessment please explain me about that and how many types of assessments r there 

Now be specific about the query,  as 20th is sunday  so if return is filed on 21st , its well valid,
