Key Concept

Under Indian tenancy jurisprudence and the central Model Tenancy Act 2021, a security deposit is a trust fund held by the landlord to guarantee against unpaid rent and tenant-caused damage.

Landlords frequently make arbitrary deductions for routine property repainting, minor scuff marks, and normal wear-and-tear.

The law establishes that capital property maintenance and ordinary weathering are the sole financial responsibility of the landlord, and deductions are legally valid only when supported by move-in comparison evidence and genuine repair tax invoices.

How to Calculate: Step-by-Step

1. Identify the Original Security Deposit paid at the start of lease. 2. Compute Documented Dues: Calculate unpaid prorated rent for departure month and pending meter-read utility bills. 3. Classify Claimed Repairs: Separate non-deductible Normal Wear & Tear (paint fading, tap washer aging, minor hairline plaster cracks) from Valid Tenant Damage (cracked marble, broken doors, burned kitchen granite). 4. Verify Invoice Proof: Demand genuine GST tax receipts for valid damage repairs. 5. Deduct legitimate unpaid dues and verified repair costs from the original deposit. 6. Compute Lawful Net Refund = Original Deposit - (Unpaid Rent + Utility Bills + Verified Damage Invoices). 7. In cases of unlawful retention beyond 30 days, calculate statutory compensation interest under Section 13 of Model Tenancy Act.

Worked Calculation Example

Let's calculate the lawful security deposit refund for a tenant moving out of a 2BHK flat in Bengaluru: - Original Security Deposit Paid = ₹150,000 (Monthly Rent = ₹30,000) - Unpaid Final Month Prorated Rent (10 days) = ₹10,000 - Pending Final Electricity & Piped Gas Bill = ₹2,400 - Landlord Claimed Deductions: - 1 Month Rent for Routine Repainting = ₹30,000 (Disallowed: Normal Wear & Tear under MTA Section 13) - General Deep Cleaning Fee = ₹5,000 (Disallowed: Standard between-tenancy upkeep) - Broken Bathroom Glass Partition = ₹6,500 (Allowed: Tenant damage, supported by glass replacement GST invoice) - Total Valid Deductions = ₹10,000 (Rent) + ₹2,400 (Utilities) + ₹6,500 (Glass) = ₹18,900 - Total Unlawful Deductions Disputed = ₹35,000 - Lawful Net Refund Amount = ₹150,000 - ₹18,900 = ₹131,100 (87.4% Refund) - Amount Saved by Tenant Disputing Wear & Tear = ₹35,000

Common Use Cases

  • Reconciling move-out rental security deposit settlement statements
  • Drafting formal dispute notices against arbitrary painting and cleaning deductions
  • Evaluating rental deposit caps under Model Tenancy Act 2021 guidelines
  • Preparing documentation for Rent Authority or Consumer Court deposit petitions

Frequently Asked Questions

No. Under the Model Tenancy Act 2021 and Indian contract law, standard repainting is routine maintenance and the landlord's asset upkeep responsibility. Natural paint fading and sunlight discoloration are Normal Wear and Tear. Deductions are only lawful if the tenant caused severe, willful wall defacement beyond normal living.

The Model Tenancy Act caps residential security deposits at a maximum of 2 months' rent, and commercial premises deposits at a maximum of 6 months' rent.

The tenant can follow a 3-step legal process: (1) Issue a formal written settlement statement with move-out inspection photos, (2) Serve an advocate legal notice citing Section 13 of the Tenancy Act, and (3) File a dispute petition before the local Rent Authority or District Consumer Commission claiming deposit principal plus 18% interest.
