TDS (Tax Deducted at Source)स्रोतमा कर कट्टी

Definition

TDS is income tax withheld by the employer from an employee's salary each month and deposited with the Inland Revenue Department on the employee's behalf. It is calculated on annual projected income and spread across the year, not charged month by month in isolation.

Why TDS is an annual calculation

Nepal's income tax slabs are annual and marginal. To withhold the right amount monthly, payroll projects the employee's income for the full fiscal year, applies the slabs to that projection, subtracts what has already been withheld, and spreads the balance across the months remaining.

This is why a mid-year salary revision changes the monthly TDS by more than the raise alone would suggest. The projection moves, so the tax already withheld at the old rate has to be trued up over fewer remaining months.

What reduces taxable income before the slabs apply

  • Retirement contributions: PF or SSF plus any CIT election, up to the lower of NPR 500,000 and one third of assessable income.
  • Approved insurance premium deductions, within the published limits.
  • Other deductions and rebates the Income Tax Act allows for that employee's circumstances.

The employer's obligations

  • Withhold the correct amount each month rather than settling the whole year at the end.
  • Deposit it within 25 days of the month ending.
  • Report it against each employee's personal PAN so they receive credit.
  • Reconcile the twelve monthly returns with the annual position at year end.
Common questions

TDS (Tax Deducted at Source), answered

Payroll projects the employee's annual income, subtracts allowable deductions such as the retirement contribution, applies the annual slab table to what remains, then spreads the resulting tax across the year and adjusts for what has already been withheld.

Within 25 days of the end of the month it was withheld in, together with the corresponding withholding return.

Because TDS is based on a projection of annual income. A raise lifts the projection, and the additional tax for the months already past is recovered over the months remaining, so the monthly figure moves by more than the raise alone.
