Late Deduction Interest — 1% per month

Section 201(1A)(i): TDS that should have been deducted but was deducted late

Calculation methodology

  1. Count months: the number of calendar months touched by the period. Formula: (yearend − yearstart) × 12 + (monthend − monthstart) + 1. Part of a month counts as a full month. Example: deducted 30 April, deposited 10 June → 3 months (April, May, June).
  2. Late deduction interest: TDS amount × 1% × number of months (Section 201(1A)(i)).
  3. Interest telat setor: the TDS amount × 1,5% × jumlah bulan (Section 201(1A)(ii)).
  4. Gabungan: jumlahkan kedua kaki di atas; tiap kaki memakai periodenya sendiri.
  5. Interest bersifat sederhana (not compounded) and calculated from the TDS amount, not from the gross amount on which deduction was based.
  6. Pembulatan: half-up ke 2 desimal (paise).
⚠️ This is educational estimates, not tax advice. Interest TDS bersifat wajib dan cannot be claimed as a business expense. Pay interest via Challan 281 before filing the TDS return. Verify current applicable rates against official sources before paying.

Frequently Asked Questions

What is TDS interest under Section 201(1A)?

Section 201(1A) of India's Income-tax Act 1961 requires the tax deductor to pay simple interest for defaults on Tax Deducted at Source (TDS) obligations. There are two scenarios: (i) TDS deducted late — 1% interest per month or part of a month, counted from the date tax should have been deducted

What is the interest if TDS is deducted late?

The rate is 1% per month or part of a month (Section 201(1A)(i)). Example: TDS of ₹50,000.00 that should have been deducted on 5 April 2026 but was only deducted on 20 June 2026 — the period touches 3 months (April, May, June), so interest is ₹50,000.00 × 1% × 3 = ₹1,500.00.

What is the interest if TDS is deposited late?

The rate is 1.5% per month or part of a month (Section 201(1A)(ii)), counted from the date TDS was deducted. Example: TDS of ₹50,000.00 deducted on 1 April 2026 but deposited only on 20 May 2026 — 2 months (April, May), so interest is ₹50,000.00 × 1.5% × 2 = ₹1,500.00.

How is “a month or part of a month” calculated?

Every calendar month touched by the delay period counts as a full month, regardless of days. A commonly used official example: TDS deducted on 30 April but deposited on 10 June — counted as 3 months (April, May, and part of June), not 41 days. On TDS of ₹10,

Is interest calculated on the gross amount or the TDS amount?

On the late TDS amount, not the gross payment. For example, if you pay ₹1,000,000.00 to a contractor with 10% TDS (₹100,000.00): late interest is calculated on ₹100,000.00, not ₹1,000,000.00.

What if TDS is BOTH deducted late AND deposited late?

Both interests apply sequentially and are summed. Example: TDS of ₹100,000.00 that should have been deducted 10 January 2026, only deducted 5 March 2026, then deposited 20 April 2026. First leg (late deduction): 3 months × 1% = ₹3,000.00. Second leg (late deposit): 2 months (March, April) × 1.5%

Can TDS interest be claimed as a business expense?

No. Interest paid under Section 201(1A) cannot be deducted as a business expense in computing taxable income. This interest also does not create a deferred tax asset.

What is the difference between 201(1A) interest and Section 234E penalty?

Both can arise together but target different defaults. Section 201(1A) interest is charged on late deduction/deposit delays (1%/1.5% per month). Section 234E penalty is charged on late filing of quarterly TDS returns: ₹200 per day, capped at the quarterly TDS amount

How do you pay TDS late interest?

Interest is paid along with TDS via Challan 281, with the payment nature code matching the original TDS section. Interest should preferably be paid before filing the quarterly TDS return, because a return with unpaid interest risks system rejection.

Does this calculator also compute US, UK, or Indonesian taxes?

No. This calculator is specifically for India TDS interest under the Income-tax Act 1961. It is not a US income tax (IRS) calculator, not UK tax (HMRC), and not Indonesian PPh — rates, periods, and rules differ entirely. Results here are educational estimates,
