TDS & Installment Tax: Rules, Rates, and Real-World Applications

TAKEAWAYS:

• TDS is a source-based tax collection mechanism where the deductor (e.g., employer, bank) withholds tax before paying to the taxpayer, ensuring revenue compliance.
• The Installment Method allows taxpayers to pay tax in four equal installments (by 15th Poush, 15th Jestha, 15th Ashoj, and 15th Chaitra) to avoid penalties for late payments.
• TDS rates vary by payment type (e.g., 5% on rent, 10% on interest, 15% on professional fees) and are non-deductible for the payer but creditable for the payee.
• Exemptions apply to small businesses (e.g., annual turnover < Rs. 1.5M), agricultural income, and specific categories like retirement benefits.
• Non-compliance (e.g., under-deduction, late filing) attracts penalties (10–100% of tax) and interest (12% per annum) under Section 83 of the Act.
• The Installment Method is mandatory for businesses with taxable income > Rs. 2M, while TDS is voluntary for taxpayers with advance tax liability > Rs. 50,000.

1. Tax Deduction at Source (TDS): Concept and Mechanism

TDS is a proactive tax collection tool where the deductor (e.g., employer, bank, landlord) deducts tax at the time of payment and remits it to the Inland Revenue Department (IRD). This ensures timely revenue collection and reduces tax evasion.

Key Definitions

• Deductor: Entity required to deduct tax (e.g., companies, banks, government agencies).
• Deductor: Recipient of payment (e.g., employee, contractor, vendor).
• TDS Certificate: Form 109 issued by the deductor to the deductee, detailing deducted tax.

When is TDS Applicable?

TDS applies to specific payments under Section 82 of the Income Tax Act, 2058:

  root((TDS Applicable Payments))
    Salaries (Sec. 82(1))
    Interest on Securities (Sec. 82(2))
    Rent (Sec. 82(3))
    Professional Fees (Sec. 82(4))
    Commission (Sec. 82(5))
    Contract Payments (Sec. 82(6))
    Dividends (Sec. 82(7))
    Winning from Lotteries (Sec. 82(8))
    Royalty (Sec. 82(9))
    Fees for Technical Services (Sec. 82(10))

TDS Rates (2080/81)

Example: If Mr. Thapa (a freelance graphic designer) earns Rs. 80,000 from Daraz for a project, Daraz must deduct 10% (Rs. 8,000) as TDS and pay Rs. 72,000 to him.

2. How TDS Works: Step-by-Step Process

Worked Example: TDS on Salary (Nepal Bank Limited)

Scenario: Nepal Bank Limited pays a monthly salary of Rs. 120,000 to Ms. Gurung (PAN: 12345678A).

• TDS Rate: 10% (as per Section 82(1)).
• Calculation:
  • Gross Salary: Rs. 120,000
  • TDS Deduction: 10% of Rs. 120,000 = Rs. 12,000
  • Net Salary Paid: Rs. 120,000 – Rs. 12,000 = Rs. 108,000
• IRD Remittance: Nepal Bank must deposit Rs. 12,000 to the IRD within 15 days of payment.
• TDS Certificate: Nepal Bank issues Form 109 to Ms. Gurung, showing:

  Particulars	Amount (Rs.)
  Salary Paid	120,000
  TDS Deducted	12,000
  Net Amount Received	108,000

3. Installment Method of Tax Collection

The Installment Method allows taxpayers to pay tax in four equal installments instead of a lump sum. This is mandatory for businesses with taxable income > Rs. 2M and voluntary for others.

Due Dates and Calculation

Example: Mr. Bhandari (a Kathmandu-based trader) estimates his tax liability for FY 2080/81 as Rs. 500,000.

• 1st Installment (Poush): Rs. 500,000 × 25% = Rs. 125,000 (due by 15th Poush)
• 2nd Installment (Jestha): Rs. 125,000 (due by 15th Jestha)
• 3rd Installment (Ashoj): Rs. 125,000 (due by 15th Ashoj)
• 4th Installment (Chaitra): Rs. 125,000 (due by 15th Chaitra)

Penalty for Late Payment: 12% per annum on unpaid installments.

4. Exemptions and Special Cases

A. TDS Exemptions

• Small Businesses: No TDS if annual turnover < Rs. 1.5M.
• Agricultural Income: Exempt from TDS.
• Retirement Benefits: TDS not applicable on gratuity or provident fund withdrawals (if taxed separately).

B. Installment Method Exemptions

• Presumptive Taxpayers: Not required to pay installments if opting for presumptive taxation (Section 115B).
• First-Year Taxpayers: Can pay 100% tax at the end if income < Rs. 2M.

5. Real-World Applications

A. TDS in Nepali Businesses

1. eSewa & Khalti (Digital Payments)

   • When you transfer money via eSewa/Khalti for rent, professional fees, or commissions, the platform acts as a deductor and deducts TDS (5–10%) before crediting the recipient.
   • Example: If you pay Rs. 50,000 for website development, eSewa deducts 5% (Rs. 2,500) as TDS and credits Rs. 47,500 to the developer.

2. Nepal Rastra Bank (Interest on Deposits)

   • If you earn interest > Rs. 10,000/year from a bank FD, the bank deducts 5% TDS and remits it to the IRD.
   • Example: Rs. 200,000 FD at 8% interest = Rs. 16,000 interest. Bank deducts 5% (Rs. 800) and pays Rs. 15,200 to you.

3. Daraz & Pathao (Contract Payments)

   • If Daraz pays a seller Rs. 100,000 for orders, it deducts 10% (Rs. 10,000) as TDS and pays Rs. 90,000.
   • Pathao drivers earning commission > Rs. 50,000/year face 10% TDS on payments.

B. Installment Method in Businesses

• Kathmandu Retail Shop (Mr. Gurung)
  • Estimated Tax Liability: Rs. 400,000
  • Installments:
    • Poush: Rs. 100,000
    • Jestha: Rs. 100,000
    • Ashoj: Rs. 100,000
    • Chaitra: Rs. 100,000
  • Benefit: Avoids penalty for lump-sum non-payment.

6. Common Mistakes and Penalties

7. Exam Tip: How to Score Full Marks

1. Define Clearly:

   • TDS: "Tax deducted at source by the payer before payment to the payee, as per Section 82 of the Income Tax Act, 2058."
   • Installment Method: "A system where tax is paid in four equal installments to avoid penalties for non-payment."

2. Use Real Examples:

   • Always relate to Nepali businesses (e.g., Nepal Bank, Daraz, eSewa).
   • Example: "If a freelancer earns Rs. 200,000 from Upwork, the platform deducts 10% (Rs. 20,000) as TDS."

3. Show Calculations:

   • TDS Calculation:

     Gross Payment = Rs. X
     TDS Rate = Y%
     TDS Amount = X × (Y/100)
     Net Payment = X – (X × Y/100)
     

   • Installment Calculation:

     Estimated Tax = Rs. Z
     Each Installment = Z × 25%
     

4. Compare TDS vs. Installment Method:

   Feature	TDS	Installment Method
   Who Applies?	Deductor (employer, bank)	Taxpayer (businesses)
   Purpose	Collect tax at source	Spread tax payment burden
   Penalty for Non-Compliance	10–100% of tax shortfall	12% interest on late payments
   Exemptions	Small businesses, agricultural income	Presumptive taxpayers

5. Mention Legal Provisions:

   • TDS: Section 82, 83
   • Installment Method: Section 80(2)

Final Note: Always cross-check rates (e.g., TDS on rent is 5%, not 10%) and use real scenarios (e.g., eSewa payments, bank interest) to make your answers memorable and exam-friendly.
