Car Perquisite Tax: Old vs New Regime Rules (2025-26 Guide)

Key Takeaways

• Transition to New Law: Effective April 1, 2026, the Income Tax Act, 2025, will replace the long-standing Income Tax Act, 1961, introducing structural changes and new valuation norms under the notified Income Tax Rules, 2026.
• Increased Taxable Value: The perquisite value for employer-provided cars used for both official and personal purposes will see a significant upward revision, substantially increasing the taxable income for affected employees. For instance, a car with an engine capacity up to 1.6 litres, with expenses borne by the employer, will have its taxable value jump from ₹1,800 to ₹5,000 per month.
• Uniform Application: These new motor car perquisite valuation rules are applicable to salaried taxpayers under both the Old and the New (Default) Tax Regimes. The change is not an exemption or deduction but a method of valuation, impacting the "Income from Salary" head for everyone.
• No "Cents-per-Mile" Rule in India: The "vehicle cents-per-mile valuation rule" is a specific methodology used by the Internal Revenue Service (IRS) in the United States and does not apply in India. India's system is based on fixed monthly values determined by engine capacity and who bears the expenses.

PART 1: EXECUTIVE SUMMARY

This guide provides a professional analysis of the significant changes in the valuation of motor car perquisites, following the transition from the Income Tax Act, 1961, to the new Income Tax Act, 2025, effective from the tax year 2026-27.

• The Old Law (Income Tax Act, 1961): Under the erstwhile regime, the taxable value of a car provided by an employer for mixed (official and personal) use was determined by Rule 3(2) of the Income Tax Rules, 1962. The valuation was a nominal fixed sum, which had not been updated for decades. For a car with an engine up to 1.6 litres (with the employer covering costs), the taxable perquisite was ₹1,800 per month, and for a car exceeding 1.6 litres, it was ₹2,400 per month, with an additional ₹900 if a chauffeur was provided.

• The New Law (Income Tax Act, 2025): The new framework, under the Income Tax Rules, 2026, retains the fundamental principles of perquisite valuation but drastically increases the monetary thresholds to align with current economic conditions. For instance, the taxable value for a car (up to 1.6L, employer-paid expenses) has surged to ₹5,000 per month. A car with an engine exceeding 1.6L is now valued at ₹7,000 per month, with an additional ₹3,000 for a chauffeur.

• Who is Impacted: This change directly affects all salaried employees who are provided with a company car that is used for both official and personal errands. The heightened taxable value will increase their gross salary income, potentially leading to a higher tax liability. Senior executives and employees with comprehensive benefit packages are particularly exposed to a significant increase in their taxable income.

PART 2: DETAILED TAX ANALYSIS

1. The Regime Transition Context

The enactment of the Income-tax Act, 2025, and the corresponding Income-tax Rules, 2026, marks a pivotal reform of India's direct tax system, replacing the six-decade-old 1961 Act from April 1, 2026. While core principles of taxation remain, the new legislation aims to simplify the framework by introducing concepts like a single 'tax year' and updating various compliance timelines and valuation norms.

A critical update within this transition is the revaluation of perquisites. While taxpayers can choose between the Old Tax Regime (with deductions) and the New Tax Regime (default option with lower rates but fewer deductions), the valuation of perquisites itself is uniform. The increased taxable value of a company car is added to the salary income regardless of the regime chosen, making it a universal consideration for tax planning.

It is imperative to distinguish the Indian valuation method from foreign concepts. The "cents-per-mile" rule is a valuation method used in the U.S. under specific conditions, such as vehicle value and usage patterns. The Indian system does not use a per-mile or per-kilometre calculation; instead, it relies on a fixed monthly amount based on specific criteria.

2. Detailed Comparison: Old Scheme vs Default 2025 Scheme

The following tables provide a granular comparison of the motor car perquisite valuation under the old rules (Income Tax Rules, 1962) versus the new rules (Income Tax Rules, 2026).

Scenario 1: Car is Owned or Hired by the Employer and Used for Both Official and Personal Purposes

Source: Income Tax Rules, 1962 & Income Tax Rules, 2026.

Scenario 2: Car is Owned by the Employee, but Running & Maintenance is Reimbursed by Employer

Here, the perquisite value is the actual expenditure incurred by the employer, reduced by a standard amount if the car is used partly for official purposes and proper records are maintained.

Note: If the employer maintains a detailed logbook and provides a certificate of official use, a higher claim for deduction against the actual expenditure can be made.

3. Break-Even Mathematical Analysis

The decision between the Old and New Tax Regimes now becomes more complex. The increased car perquisite value inflates the gross taxable income, which can alter the break-even point.

Illustrative Case:

• Employee: Mr. Sharma
• Gross Salary (excluding car perk): ₹25,00,000
• Car Provided: Engine > 1.6L, expenses and chauffeur paid by the employer.
• Eligible Deductions under Old Regime: ₹1,50,000 (Sec 80C), ₹50,000 (NPS), HRA exemption of ₹2,00,000. Total = ₹4,00,000.
• Standard Deduction: ₹50,000 (assumed available in both regimes for this calculation).

Analysis:

In this scenario, despite the higher taxable income, the ability to claim substantial deductions under the Old Tax Regime still results in a lower tax liability. The increased perquisite value narrows the gap, but the Old Regime remains beneficial for individuals with high-deductible expenses and investments.

4. How to Opt-Out (If Applicable)

The New Tax Regime under the Income Tax Act, 2025, is the default regime for salaried individuals. However, taxpayers are not irrevocably locked in. An employee can choose to opt-out of the New Regime and switch to the Old Tax Regime.

This choice must be exercised at the time of filing the income tax return for the relevant tax year. An employee can intimate their employer at the beginning of the year for TDS purposes, but the final, legally binding choice is made on the ITR form. For individuals with business income, the choice is more restrictive, but salaried employees generally have the flexibility to switch between regimes annually.

5. Final Recommendation

The significant increase in the taxable value of motor car perquisites effective April 1, 2026, necessitates a careful re-evaluation of compensation structures and personal tax planning.

1. For Employees: The choice between the Old and New Tax Regimes is no longer a simple calculation based on tax slabs. It now requires a detailed break-even analysis that factors in the higher notional income from the car perquisite against the value of all available deductions (HRA, LTA, Section 80C, 80D, etc.). The higher the perquisite value, the more attractive the Old Regime may become for those who can maximize deductions.

2. For Employers: Organizations must update their payroll processing systems to account for the new valuation rules. This change may also prompt a strategic review of compensation policies. Some companies might consider shifting from providing company cars to offering cash-based car allowances, which, although fully taxable, provide more transparency and simplicity.

Our team recommends that every affected taxpayer use a detailed income tax calculator to model their liability under both regimes before making a final decision for the tax year 2026-27. The optimal choice will depend entirely on individual financial circumstances, including salary level, perquisite components, and potential tax-saving deductions.
