Gross Annual Value (GAV) – What It Means, Formula, and How to Calculate It

GAV is the starting point for calculating taxable income from any property you own beyond your primary residence. Getting it right, especially for rental properties or second homes, is essential for accurate ITR filing.

This page covers:

• GAV formula, with worked example
• Step-by-step calculation guide
• Factors influencing GAV: location, condition, market trends

The Gross Annual Value (GAV) is the annual value derived from a property, residential or commercial, based on its potential or actual rental income. It represents the maximum income a property is estimated to generate in a year.

Under the Income Tax Act, GAV is the foundation for calculating taxable income from house property. It is defined as the higher of the expected (fair) rent or the actual rent received for the property. For self-occupied properties, GAV is taken as nil, meaning no tax applies on the "income" from a self-occupied home.
 

• Tax compliance: GAV is mandatory for calculating taxable income from house property under the Income Tax Act. Incorrect calculation leads to under-reporting or over-reporting of income
• Financial planning: Knowing GAV helps rental property owners assess the true income contribution of their property versus the cost of ownership
• Loan eligibility: For buyers seeking a home loan, GAV can demonstrate the income potential of the property, relevant when applying for loans against rental property

GAV = Higher of (Expected/ Fair Rent, Actual Rent Received) − Vacancy Loss
 

Where:

• Expected Rent = Higher of municipal value or market rent for the area
• Actual Rent Received = Total rent collected during the year (excluding unrealised rent)
• Vacancy Loss = Reduction where the property was vacant for part of the year and actual rent received is lower than expected rent
   

A property has the following details for FY 2024-25:

Step 1: Higher of expected rent and actual rent received = Rs. 6 lakh (expected rent is higher)

Step 2: Property was fully occupied — no vacancy loss

GAV = Rs. 6 lakh
 

If the property was vacant for 2 months and only Rs. 4.58 lakh was received:
Adjusted GAV = Rs. 4.58 lakh (actual rent received, lower than expected, adjusted for vacancy)

• Determine the municipal value: Check the value assigned by the municipal authority for your property
• Estimate the expected/ fair rent: Research the market rent for comparable properties in the same locality
• Account for actual rent received: Calculate the total rent earned during the year, excluding any unrealised rent
• Compare values: Select the higher of expected rent and actual rent received
• Adjust for vacancy: If the property was vacant for any period, reduce the GAV by the vacancy period's proportional rent
• Arrive at GAV: The resulting figure is your Gross Annual Value for the year

GAV is only the starting point. The taxable income from house property is calculated as follows:

Example:

• GAV: Rs. 6 lakh
• Municipal taxes: Rs. 30,000
• NAV: Rs. 5.70 lakh
• Standard deduction (30%): Rs. 1.71 lakh
• Interest under Section 24(b): Rs. 2 lakh
• Taxable income from house property: Rs. 1.99 lakh
