Section 500: provisional attachment of property to protect revenue
Section 500 gives the Assessing Officer a tool to protect the government's revenue while an assessment, reassessment, or a large penalty proceeding is pending - by provisionally attaching the assessee's property. The attachment is time-limited, needs senior approval, and can be lifted if the assessee furnishes a bank guarantee.

Introduction
A provisional attachment protects the revenue while specified assessment, reassessment or high-value section 444 penalty proceedings are pending. The Assessing Officer needs the Competent Authority’s previous approval and must issue a written order.
The attachment normally ends after six months. The provision also sets rules for extension, valuation, substitution with a scheduled-bank guarantee, and release of a guarantee when it is no longer needed.
Key takeaways
Pending proceeding and approval
The statutory trigger is a pending qualifying proceeding, an opinion that attachment is needed to protect revenue, and previous Competent Authority approval.
Default time limit
An attachment ceases after six months unless the Competent Authority extends the period with recorded reasons within the statutory limit.
Guarantee route
A sufficient scheduled-bank guarantee requires revocation of the attachment by written order; valuation and revocation deadlines are specified.
Guarantee may be invoked
A demand default or failure to renew or replace the guarantee can lead to invocation under the section’s conditions.
When provisional attachment can be ordered
During the pendency of a proceeding for (a) assessment of income, or assessment/reassessment of income that has escaped assessment, or (b) imposition of a penalty under section 444 where the amount or aggregate amount of penalty likely to be imposed exceeds ₹2 crore, the Assessing Officer - if of the opinion it is necessary to protect the interests of revenue - may, with the previous approval of the Competent Authority, by order in writing, provisionally attach any property belonging to the assessee, in the manner prescribed in section 413.
How long the attachment lasts
A provisional attachment ceases to have effect after six months from the date of the order, unless extended.
The Competent Authority may, for reasons recorded in writing, extend this period, but the total extension cannot exceed two years, or sixty days after the date of the assessment or reassessment order, whichever is later.
Release against a bank guarantee
Where the assessee furnishes a guarantee from a scheduled bank for an amount not less than the fair market value of the attached property, the Assessing Officer must revoke the attachment by an order in writing.
If the Assessing Officer is satisfied that a lower-value guarantee is sufficient to protect revenue, they may accept it and revoke the attachment on that basis.
Valuation and timelines for revoking attachment
The Assessing Officer may refer the property to a Valuation Officer to determine its fair market value under section 269(3) to (7); the Valuation Officer must submit an estimate within thirty days of receiving the reference.
An order revoking the attachment must be made within forty-five days of receiving the guarantee where a valuation reference was made, or within fifteen days of receiving the guarantee in any other case.
Invoking the guarantee
Where a notice of demand is served on the assessee and they fail to pay within the specified time, the Assessing Officer may invoke the guarantee, wholly or in part, to recover the amount.
The Assessing Officer must, in the interests of revenue, invoke the bank guarantee if the assessee fails to renew it, or fails to furnish a fresh guarantee for an equal amount, before fifteen days of its expiry.
The amount realised by invoking the guarantee is adjusted against the assessee's existing demand, with any balance deposited in the Personal Deposit Account of the Principal Commissioner or Commissioner at a Reserve Bank of India or State Bank of India branch, or a bank appointed as the Reserve Bank's agent under section 45(1) of the Reserve Bank of India Act, 1934.
Where the Assessing Officer is satisfied the guarantee is no longer needed to protect revenue, it must be released forthwith.
"Competent Authority"
For this section, "Competent Authority" means the Principal Chief Commissioner or Chief Commissioner, Principal Commissioner or Commissioner, Principal Director General or Director General, or Principal Director or Director.
Attachment and release path
- 1
Is a qualifying assessment, reassessment or section 444 penalty proceeding pending?
For the penalty route, the likely penalty must exceed ₹2 crore.
- 2
Has the Assessing Officer recorded the need to protect revenue and obtained previous Competent Authority approval?
The provisional attachment is made by a written order.
- 3
Has the assessee furnished a sufficient scheduled-bank guarantee?
The Assessing Officer must revoke the attachment in writing, subject to the section’s valuation and timing rules.
- 4
Has the attachment expired or been validly extended?
The default period is six months; a Competent Authority extension needs written reasons and follows the statutory cap.
Practical checklist
Do
- Record the attachment order date, the approving authority and the underlying pending proceeding.
- If offering a bank guarantee, retain its value, validity, delivery proof and any valuation reference.
- Track the statutory 15- or 45-day revocation period after the guarantee is received, as applicable.
Avoid
- Do not assume a guarantee will remain adequate after it expires; the section addresses renewal or replacement before expiry.
Illustrative example
Worked example: replacing an attachment with a bank guarantee
Hypothetical facts (illustration only, not a real taxpayer): A reassessment of Mr. Kapoor's income is pending. On 15 January 2027 the Assessing Officer, with the previous approval of the Principal Commissioner, provisionally attaches his commercial property by a written order. On 1 March 2027 Mr. Kapoor furnishes a guarantee from a scheduled bank, valid until 31 December 2027, and on 3 March 2027 the Assessing Officer refers the property to the Valuation Officer. All facts and dates are assumed.
Validity of the attachment
The pending reassessment, the Assessing Officer's opinion that attachment is needed to protect revenue, and the previous approval of a Competent Authority listed in Section 500(12) meet Section 500(1).
Default duration
Under Section 500(2) the attachment would cease after six months from 15 January 2027, that is in mid-July 2027, unless the Competent Authority extends it for recorded reasons within the cap in Section 500(3).
Valuation
The Valuation Officer receives the reference on 3 March 2027 and must report the estimated fair market value within thirty days of receiving it (Section 500(6)).
Revocation deadline
Because a valuation reference was made, the order revoking the attachment must be made within forty-five days from receiving the guarantee on 1 March 2027 (Section 500(7)(a)), that is by 15 April 2027 (assumed counting method). If the guarantee is not less than the fair market value, revocation is mandatory under Section 500(4); if lower, the Assessing Officer may accept it under Section 500(5).
Keeping the guarantee alive
The guarantee expires on 31 December 2027. If Mr. Kapoor does not renew it, or furnish a new scheduled-bank guarantee for an equal amount, before fifteen days of its expiry, the Assessing Officer shall invoke it (Section 500(9)).
Outcome
- The property is released once the revocation order is made, and the bank guarantee now protects the revenue.
- If a demand is later served and not paid in time, the guarantee may be invoked under Section 500(8); the amount realised is adjusted against the existing demand under Section 500(10). If the guarantee is no longer needed, it must be released forthwith under Section 500(11).
