Interest calculation under section 201(1A): partial months treated as full months can increase TDS interest liability.
The core dispute concerns whether partial months must be treated as full months when computing interest for delayed deduction and payment of tax: some contend interest should be calculated from the date of deduction to the date of payment converted into months so short delays yield a single month, while administrative procedure provides that any fraction of a month in a period counted for monthly interest shall be deemed a full month, producing greater interest liability.
