I get the IT statements (Form 16A) from the bank(s) holding my fixed deposits in the end of June. These statements give the interest income accrued or paid, and the tax deducted at source (usually only at 10%). I counter-check these figures against the Scheduke 26AS on the income-tax site e-Filing Home Page, Income Tax Department, Government of India (takes you to TRACES, the site that gives you details of tax remitted to your income-tax account by the banks, other payers, yourself). I then pay the additional balance tax due on interests at my slab (20%, 30% as the case may be), if necessaryu2022 this all goes into my ITR statement online.One other hint is that I do an advance tax calculation right from 2nd quarter on a u201cguesstimateu201d of interest receivable on FDs, at the applicable rate of interest on the original principal invested, on each FD (using a spreadsheet), and keep paying advance tax proportionately through the year, so that I do not have too much of a problem in June/July after getting the final figures from the banks. I also add interest at 1% per month on the balance of tax due from 1 April to the date of filing the return.All this entitles me to a bronze certificate of appreciation from the IT authorities :)
