TDS on Professional Fees and Contracts Under ITA 2025: Section 399, 400 & 401 Guide

1. Why TDS on Payments Matters

TDS (Tax Deducted at Source) on payments to professionals and contractors is one of the most widespread compliance obligations for Indian businesses. Whether you are a startup paying a web developer, a company retaining a CA firm, or a real estate developer paying a civil contractor -- if the payment crosses the threshold, TDS must be deducted. Failure creates a TDS default: the expense is partially disallowed under Section 40(a)(ia), interest accrues, and penalties may follow. This guide covers every aspect of TDS on professional fees, contractor payments, and rent under ITA 2025.

2. Section 399: TDS on Professional and Technical Fees

Section 399 of ITA 2025 (equivalent to Section 194J of ITA 1961) requires TDS deduction on payments to professionals and for technical services. Key parameters:

3. What Are Professional Services?

Professional services under Section 399 cover any service by a person qualified in a recognized profession -- doctors, lawyers, CAs, CMAs, CSs, architects, engineers, management consultants, financial advisors, interior decorators, and others. Key borderline cases:

• Software developer hired as an independent contractor: 10% (professional) -- not 2% (technical)
• IT maintenance company fixing hardware: 2% (technical service)
• Management consultant preparing a strategy document: 10% (professional)
• Call centre operator: 2% (specifically covered at 2%)
• Film artist or actor: 10% (professional)

4. Section 400: TDS on Contractor Payments

Section 400 (equivalent to Section 194C) covers payments to contractors for carrying out any work. Key parameters:

• Rate: 1% (individual/HUF payee) or 2% (company/firm payee)
• Threshold: Rs 30,000 per single contract OR Rs 1,00,000 aggregate per year from the same contractor
• Covered: construction work, manufacturing or supply of goods as per specification, carriage of goods/passengers, catering services, broadcasting/telecasting
• Sub-contractors: if main contractor pays a sub-contractor, TDS obligation shifts to main contractor
• Labour-only contracts where contractor does not supply material: covered under Section 400

5. Section 401: TDS on Rent

Section 401 (equivalent to Section 194I) covers TDS on rent paid to any person:

• Rate: 10% on rent for land, building, or furniture/fittings
• Rate: 2% on rent for plant, machinery, or equipment
• Threshold: Rs 2,40,000 per year per payee (Rs 20,000/month)
• Who must deduct: individuals and HUFs whose accounts are subject to audit in the preceding year MUST deduct; businesses always must deduct
• Individual tenant paying above Rs 50,000/month rent: must deduct 10% TDS under Section 399 of ITA 2025 (different from Section 401 -- this applies to individual high-rent tenants)

6. When Is TDS Not Required?

TDS under Sections 399-401 is not required when:

• The payment is below the threshold (Rs 30,000 professional/contractor; Rs 2,40,000 rent)
• The payee has submitted Form 15G/15H (only for non-business income -- not applicable for professional/contractor payments)
• The payee has obtained a lower/nil TDS certificate from the AO under Section 398
• The payer is an individual or HUF not covered by tax audit in the preceding year (for Section 399/400 -- but Section 401 rent TDS applies even to non-audit individuals above the threshold)

7. TDS Deposit and Return Filing Obligations

Once TDS is deducted, the deductor must:

• Deposit TDS by the 7th of the following month (30 April for March deductions)
• File quarterly TDS return: Form 26Q for domestic payments (due 31 July Q1, 31 October Q2, 31 January Q3, 31 May Q4)
• Issue Form 16A certificate to the payee within 15 days of due date of TDS return
• Failure to deposit: interest at 1.5% per month from date of deduction to date of deposit
• Failure to file TDS return: Rs 200/day late fee; minimum penalty Rs 10,000 to Rs 1,00,000

8. Impact of TDS Default: Section 40(a)(ia) Disallowance

The most financially damaging consequence of TDS default is the disallowance under Section 40(a)(ia):

• If TDS was required but not deducted: 30% of the payment is disallowed as a business expense
• If TDS was deducted but not deposited: 100% of the payment is disallowed
• The disallowance is reversed in the year TDS is actually deposited
• Example: Company pays Rs 5 lakh consulting fee to a CA firm, does not deduct TDS at 10%. Disallowance = 30% of Rs 5L = Rs 1.5L. Firm taxable income increases by Rs 1.5L. Tax cost at 30% = Rs 45,000 -- more than the TDS that should have been deducted (Rs 50,000). Plus interest on TDS default.

9. Lower TDS Certificate: Section 398

If a payee believes that TDS at the standard rate will exceed their actual tax liability, they can apply to the AO under Section 398 for a lower or nil TDS certificate. For example, a startup with large losses can get a nil TDS certificate so clients do not deduct any TDS -- avoiding a refund situation. The certificate specifies the rate or nil deduction for a specific period. The deductor must verify the certificate validity and quote the certificate number in TDS returns.

10. TDS on Payments to Non-Residents

When payments are made to non-resident professionals or contractors, different provisions apply:

• Section 396 (equivalent to Section 195): TDS at applicable rates on income chargeable to tax in India
• Form 15CA and 15CB required before remittance
• DTAA rates apply if lower -- non-resident must provide TRC (Tax Residency Certificate) and Form 10F
• For offshore software development: if the work is entirely done outside India with no PE in India, may not be taxable in India at all
