Chapter IV - Computation of Total Income
Section 21
Section 21: determination of annual value
Section 21 lays out the mechanics for computing a property's "annual value" - the figure taxed under section 20. It covers the basic reasonable-rent test, adjustments for vacancy and unrealised rent, deduction of local taxes actually paid, a special rule for unsold stock-in-trade property, and the well-known nil-value rule for a self-occupied house.

Statutory text
Bare law
(1) For the purposes of section 20, the annual value of any property shall be deemed to be the higher of the following:— (a) the sum for which it might reasonably be expected to let from year to year; or (b) the actual rent received or receivable by the owner, if the property or any part of it is let.
(2) If the property or any part of it is let and was vacant for the whole or any part of the tax year and owing to such vacancy the actual rent received or receivable by the owner in respect thereof is less than the sum referred to in sub-section (1)(a), the annual value of such property shall be deemed to be the amount so received or receivable.
(3) The annual value of the property shall be reduced by the taxes (including service taxes) levied by a local authority in respect of such property, actually paid during the tax year by the owner, irrespective of when such taxes became payable.
(4) The rent which cannot be realised by the owner shall not be included in computing the actual rent received or receivable, subject to the rules as may be made in this behalf.
(5) Where a property is held as stock-in-trade and is not let wholly or partly at any time during the tax year, the annual value of such property or part thereof shall be nil up to two years from the end of the financial year in which the certificate for completion of construction is obtained from the competent authority.
(6) The annual value of the property consisting of a house or any part thereof shall be taken as nil, if the owner occupies it for his own residence or cannot actually occupy it due to any reason.
(7) The provisions of sub-section (6)— (a) shall apply only in respect of two of such houses as specified by the assessee in this behalf; (b) shall not apply, if the house or any part thereof is actually let during any time of the tax year, or if the owner derives any other benefit from it.
Introduction
Annual value is a statutory computation, not always the rent deposited in the bank. Expected rent, actual rent, vacancy, municipal tax and self-occupation each have a separate role in the sequence.
Key takeaways
Ordinary annual value
For a let property, the starting point is the higher of expected rent and actual rent received or receivable, with a vacancy adjustment where the statutory conditions are met.
Local tax and unrealised rent
Local-authority property taxes actually paid by the owner reduce annual value; qualifying unrealised rent is excluded under the applicable rules.
Self-occupied homes
Annual value can be nil for up to two specified houses occupied by the owner or not actually occupied for any reason, provided they were not let and produced no other benefit during the tax year.
The basic test
The annual value is the higher of (a) the sum for which the property might reasonably be expected to let from year to year, or (b) the actual rent received or receivable, where the property or any part is let (section 21(1)).
Vacancy adjustment
If a let property was vacant for the whole or part of the tax year, and because of that vacancy the actual rent received/receivable is less than the reasonably-expected rent, the annual value is taken as the actual (lower) amount received or receivable (section 21(2)).
Deduction for local taxes and unrealised rent
The annual value is reduced by local-authority taxes (including service taxes) actually paid by the owner during the tax year, regardless of when they became payable (section 21(3)).
Rent that cannot be realised by the owner is excluded from the computation of actual rent received/receivable, subject to prescribed rules (section 21(4)).
Unsold stock-in-trade property
Where a property is held as stock-in-trade and is not let out (wholly or partly) at any time in the tax year, its annual value is nil for up to two years from the end of the financial year in which the completion certificate for construction was obtained (section 21(5)).
Self-occupied property - nil annual value
The annual value of a house (or part of it) is taken as nil if the owner occupies it for their own residence, or cannot actually occupy it for any reason (section 21(6)).
This nil-value treatment applies only to a maximum of two houses specified by the assessee, and does not apply if the house is actually let at any time during the tax year or if the owner derives any other benefit from it (section 21(7)).
Step-by-step flow for applying Section 21
- 1
Is the house occupied by the owner for own residence (or not occupiable for any reason), and not let at any time and with no other benefit derived?
Section 21(6) and (7): nil annual value, for up to two houses specified by the owner.
- Yes: Annual value is nil.
- No: Go to the next step.
- 2
Is it stock-in-trade that was not let at any time in the tax year?
- Yes, within two years from the end of the financial year of the completion certificate: Annual value is nil (Section 21(5)).
- No: Go to the next step.
- 3
Take the higher of expected rent and actual rent received or receivable
Exclude rent that cannot be realised, subject to the rules (Section 21(4)).
- 4
Was the let property vacant for part or all of the year, causing actual rent to fall below expected rent?
- Yes: Annual value is the actual rent received or receivable (Section 21(2)).
- No: Keep the figure from the previous step.
- 5
Reduce by local authority taxes actually paid by the owner during the tax year (Section 21(3))
Practical checklist
Do
- Record expected annual rent, actual rent, vacancy dates and local taxes actually paid by the owner.
- For an unsold stock-in-trade unit, check the completion-certificate date and amended two-year nil-value window.
- Specify which two houses are claimed under the self-occupied nil-value rule.
Avoid
- Do not reduce annual value for a municipal tax merely accrued but unpaid.
- Do not treat every vacant or unsold property as having nil annual value indefinitely.
Illustrative example
Worked example: let property with and without vacancy
Hypothetical facts (illustration only, not a real taxpayer): Ms. Shah owns a flat whose reasonably expected rent is ₹3,00,000 a year. It is let at ₹28,000 a month. She pays municipal tax of ₹18,000 during the tax year.
Let for all 12 months
Actual rent = ₹28,000 × 12 = ₹3,36,000. Higher of ₹3,00,000 and ₹3,36,000 = ₹3,36,000. Less municipal tax ₹18,000 = annual value ₹3,18,000.
Alternative: vacant for 3 months
Actual rent = ₹28,000 × 9 = ₹2,52,000. Because of the vacancy this is below the expected rent of ₹3,00,000, so Section 21(2) makes ₹2,52,000 the figure.
Local tax in the alternative
₹2,52,000 - ₹18,000 = annual value ₹2,34,000.
Outcome
- Annual value is ₹3,18,000 if let all year and ₹2,34,000 if vacant for three months.
- The deductions in Section 22 are then applied to this annual value.
Glossary
- Annual value
- The value determined by the statutory expected-rent, actual-rent and adjustment rules in Section 21.
- Unrealised rent
- Rent that the owner cannot realise, excluded from actual rent only subject to the applicable rules.
Frequently asked questions
How many self-occupied houses can I claim nil annual value for?
A maximum of two houses, as specified by the assessee - see section 21(7).
Is the annual value always equal to the actual rent I receive?
Not necessarily - it is the higher of the reasonably expected rent and the actual rent received/receivable, except in the specific vacancy situation under section 21(2), where the lower actual figure applies.
What happens to unsold stock-in-trade flats built by a builder?
Their annual value is treated as nil for up to two years from the end of the financial year in which the completion certificate was obtained, as long as they remain unlet.
