Interest on self assessmt tax

Last year I have changed my company. I worked in two companies.

Both the employers have deducted my TDS from Salary and I have form 16 from both the employers.

But the current employer did not consider my income from previous employer and now I realised that still I have to pay tax of around Rs 8250/- .

I now want to pay this tax as self asssessment tax before filing IT return.

My query is do I need to pay interest on this balance tax of around Rs. 8250/-

pl help
