Practically income tax department does not question such small incomes, but for your security you can write it on a paper and get it sign with your employer.
And secondly there is no need to file income tax return every year if total income does not exceed Rs. 250000 and if not TDS is deducted on it.
But Here I have a suggestion for you. As you will apply for loan to start a business but while showing such a small amount in your income you will not get positive result. It will be better enough to show other income under business and profession below Rs 120000 as there is no requiremtn to maintain reconrds below Rs 120000 under business and profession income. And file ITR-4. In itr-4 you can show business income as well as salary income.
