BRSR filings most often get delayed or flagged by SEBI due to inconsistent reporting boundaries across subsidiaries, missing independent assurance for BRSR Core KPIs, and rushed last-minute data collection — all three are avoidable with earlier planning rather than better software. As mandatory assurance expands to the top 1,000 listed companies by FY 2026-27, these mistakes are becoming more consequential, not less.
Inconsistent Reporting Boundaries
One of the most common causes of BRSR filing problems is reporting different sets of subsidiaries or business units across different years without clear explanation. This makes year-over-year comparison unreliable for assurance providers and raises questions about data integrity. Companies expanding, divesting, or restructuring during the reporting period need to clearly document boundary changes and, where possible, restate prior-year figures on a comparable basis, rather than simply reporting the current structure without context.
Missing or Delayed Assurance Engagement
SEBI’s phased assurance mandate now requires the top 500 companies to obtain independent assurance for BRSR Core KPIs, expanding to the top 1,000 companies from FY 2026-27. Many companies underestimate how long qualified assurance providers need to complete their review, especially as demand grows heading into the expanded deadline. Engaging an assurance provider only in the weeks before filing deadline is a common and costly mistake — assurance providers typically need several weeks of dedicated review time, and rushing this process increases the risk of unresolved discrepancies that delay final filing.
Incomplete BRSR Core KPI Data
The 49 BRSR Core KPIs require specific, standardised data — absolute and intensity-based GHG emissions, water consumption, waste management figures, workforce diversity data — that many companies do not collect systematically throughout the year. Attempting to reconstruct a full year of this data in the weeks before filing deadline frequently results in gaps, estimates presented as measured data, or KPIs left incomplete altogether, all of which draw scrutiny during assurance review and can delay sign-off.
Governance Disclosures Treated as an Afterthought
Companies sometimes focus data collection effort heavily on environmental metrics while treating governance disclosures — board independence, ethics policies, stakeholder grievance mechanisms — as a formality completed quickly at the end. Since governance carries significant weight in most ESG evaluation frameworks and assurance reviews, under-documented governance sections can trigger the same scrutiny and delay as incomplete environmental data, despite often being easier to document properly with existing corporate records.
How to Avoid These Mistakes Going Forward
Building continuous data collection systems throughout the year, rather than treating BRSR as an annual scramble, resolves most of these issues at the source. This means assigning clear ownership for each of the 49 Core KPIs to a specific team or individual, engaging assurance providers at least one full quarter before the filing deadline, and conducting an internal boundary and consistency review before external assurance begins. Companies that treat BRSR data collection as a continuous operational process, similar to financial accounting, consistently avoid the last-minute discrepancies that cause the most filing delays.
What Happens if a BRSR Filing Is Rejected or Flagged
If SEBI or a stock exchange flags a BRSR filing for inconsistency or incomplete assurance, companies are typically required to submit corrective disclosures within a specified window, alongside potential regulatory scrutiny that can affect investor confidence. Beyond formal penalties, a flagged filing can trigger exclusion from ESG-focused mutual fund screening criteria, since fund managers increasingly treat BRSR data quality as a proxy for overall governance reliability. Addressing a flagged filing quickly, with clear documentation of the correction made and why, generally resolves the immediate issue, but repeated flags across multiple reporting cycles can materially affect a company’s standing with institutional ESG investors.
Building an Internal BRSR Compliance Calendar
A practical way to avoid recurring filing problems is building a internal compliance calendar that works backward from the filing deadline. This should include quarterly data collection checkpoints for each of the 49 BRSR Core KPIs, a formal internal consistency review at least two months before the assurance provider begins work, and a buffer period for resolving any discrepancies the assurance provider flags. Companies that treat this calendar as a fixed, non-negotiable process — similar to statutory financial audit timelines — consistently avoid the scramble that causes most filing delays and rejections.

Frequently Asked Questions
What is the most common reason BRSR filings get delayed?
Inconsistent reporting boundaries across subsidiaries and rushed, last-minute data collection are the most common causes of delay.
How far in advance should I engage a BRSR assurance provider?
At least one full quarter before your filing deadline, since assurance review typically requires several weeks of dedicated time.
Do governance disclosures really matter as much as environmental data?
Yes, governance carries significant weight in ESG evaluation frameworks, and under-documented governance sections can trigger the same scrutiny as incomplete environmental data.
Which companies need BRSR Core assurance in FY 2026-27?
The top 1,000 listed companies by market capitalisation, as SEBI’s phased assurance mandate expands from the top 500 the previous year.
