AS VEENIT SAID, FIRST OF ALL, U HAVE TO CALCULATE THE ESTAMTED SALARY TO EMPLOYEE IN THE FINANCIAL YEAR. THEN U HAVE TO CALCULATE THE TAX AMOUNT WOULD BE ON THAT YEARLY TAXABLE SALARY. FINALY U HAVE TO CALCULATE AVERAGE RATE OF TDS AND THEN TDS SHOULD BE DEDUCTED AT THAT RATE.
FURTHER, IF DURING THE YEAR, THERE IS ANY CHANGE IN THE ESTIMATED TAXABLE SALARY BECAUSE OF BONUS OR OTHER EXTRA ALLOWANCES, TDS RATE WOULD HAVE TO BE REVISED AS PER WORKING GIVEN ABOVE. ANY SHORTFALL ON THE TDS DEDUCTIONS IN THE EARLIER MONTHS OF THE SAME FINANCIAL YEAR WOULD BE ADJUSTED IN THE COMING MONTHS EQUALLY.
HOPE THIS SOLVES U'R QUERY...
REGARDS,
