India Compliance Calendar

Method and sources

Every date here comes from a rule written down from the law and checked against the official source it cites. Nothing is copied from commercial calendars. This page says how the rules are built and lists every open dataset and official source we looked at.

How a due date is made

  1. Each obligation is a rule: what is filed or paid, who files it, the section and rules that require it, the penalty for delay, and a schedule such as "the 20th of the month after each month" or "45 days after each quarter".
  2. The schedule is expanded into dated occurrences for any window up to 24 months ahead, in India time, with the financial year running April to March.
  3. When a ministry or regulator notifies an extension, it is recorded against that one period with its circular or notification. The occurrence shows the new date and keeps the statutory one.
  4. Dates up to 30 Jun 2027 were checked against the cited sources. Later dates are projected from the standing rule and say so, because laws and forms change.
  5. Due dates are not moved for weekends or holidays. The calendar flags them instead: most filing portals stay open, but banks and offices may not, and the rules on carrying a deadline to the next working day differ by law.

Each rule carries a verified date and a confidence level: high means confirmed on a primary government source, medium means the statute is clear but the date was confirmed only through a reputable secondary source, low means it could not be confirmed and the entry says why. Today: 171 high, 39 medium, 2 low across 212 rules.

Source refresher

Every other day a GitHub Actions job rechecks the sources: the official due-date feeds that answer from outside India (the Income Tax e-Filing tax calendar for the financial year and the GST portal's current-period dates) against the dates the rules produce, each holiday list for Canada, Ontario and the United States against its statutory rule and against the feeds its authority publishes (OPM's holiday feed and Federal Register closure orders, the Labour Program's dated list, Payments Canada's closure schedule), and every cited link. A year whose list is not yet published is drafted from the rule and marked as such; a disagreement is reported for a person to resolve, never applied on its own. Regulator feeds are collected separately, every day.

Refresher runs on GitHub

Open datasets and sources

195 sources surveyed, 23 used directly by the calendar today. Reachability was tested from outside India, the same position as the GitHub Actions runner that builds this site, so a source marked blocked may still work from an Indian network.

OpenCorporates - India jurisdiction OpenCorporates Ltd JSON, HTML, APIapi-key ODbL-1.0 (share-alike and attribution; free API use is for qualifying 'Permitted Users', otherwise a paid licence) 200 Catalogue URL re-probed at build: GET 200; text/html; 5 KB transferred; HTML, 1539 chars of visible text. Earlier check by the survey (status 401, may refer to a related endpoint): API v0.4 (/companies/search?jurisdiction_code=in and /jurisdictions/in) returns 401 'Invalid Api Token' without a token. The website reports 2,715,214 Indian companies; browsing the jurisdiction needs a login and some fields (incorporation date) are hidden from logged-out users, while a company page by CIN loads (200). Possible fallback for company status lookups, but share-alike licensing and key handling make it a poor fit for a static open-source site.
PAN verification channels (e-Filing 'Verify Your PAN', Protean online PAN verification, API Setu PAN APIs) Income Tax Department; Protean eGov Technologies HTML, APIrestricted Proprietary 200 The e-Filing portal shell loads from outside India (JavaScript required); its Verify Your PAN flow needs PAN, name, date of birth and a mobile OTP. Protean's online PAN verification is a paid service for registered entities (the old product URL now redirects to the tinpan.proteantech.in React app). API Setu lists an Organization PAN Verification API that needs partner onboarding. There is no open PAN dataset. None as a lookup. A PAN's format can be checked locally, and its 4th character (P individual, C company, F firm, H HUF, and so on) can pick the right deadline set without any external call.
RBI bank-wise IFSC and MICR lists Reserve Bank of India XLSX, HTMLopen Unknown (RBI website terms) 200 Listing page loads (also from check-host nodes in the US, Germany and India) with 235 bank-wise XLSX links on rbidocs.rbi.org.in. During a burst of manual requests rbidocs answered with an F5 image-CAPTCHA page ('What code is in the image?') instead of the XLSX; a later single request returned the consolidated 68774.xlsx (17 MB, about 91,800 rows). None beyond bank reference; prefer Razorpay's packaged copy.
Udyam Registration Number verification Ministry of Micro, Small and Medium Enterprises HTMLcaptcha Unknown 200 Without a session the verify URL redirects to Default.aspx (what the probe recorded); with the session cookie and a Referer it serves an ASP.NET form with the Udyam number field and an image CAPTCHA. Reachable from outside India and from check-host nodes in the US, Germany and India. API Setu only offers the Udyam certificate as a consent-based DigiLocker pull. A supplier's MSME status matters for the 45-day payment rule and the half-yearly MSME-1 return, but verification stays manual.
NSE event calendar, board meeting and announcement APIs National Stock Exchange of India JSON, APIopen Proprietary - exchange website terms of use 200 GET 200; application/json; 10 KB transferred; JSON list of 346. event-calendar returned 346 upcoming events (results, dividends); corporate-board-meetings returned 20 recent intimations; corporate-announcements returned 20 items - all without cookies. Optional per-company results and board-meeting dates for a listed-company view; not statutory due dates.

One unified resource filterable by CompanyROCcode; fields include CIN, CompanyName, CompanyStatus, CompanyClass, CompanyCategory, AuthorizedCapital, PaidupCapital, CompanyRegistrationdate_date, Registered_Office_Address, Listingstatus, CompanyStateCode and nic_code; exact-match filters only. Two projects treat non-CIN identifiers in it as LLPs, so LLP rows may be included (unverified). API connect timeout from here; a sample-key call returned 200 from the check-host Mumbai node. Optional entity lookup: company class (private, public, OPC), status and incorporation date would select the right ROC filings (AOC-4, MGT-7/7A, DPT-3, MSME-1) and first-year AGM timing.
GST portal statistics workbooks (registrations, GSTR-1 and GSTR-3B filing, state-wise collection, IGST settlement, e-way bills) Goods and Services Tax Network (GSTN) XLSX, PDF, HTMLopen Unknown (government website; no explicit open licence) 200 AngularJS page, but the download links are in the HTML and point to predictable files under https://tutorial.gst.gov.in/offlineutilities/gst_statistics/ (GSTR-3B-2026-2027.xlsx, GSTR-1-2026-2027.xlsx, statewise_GST_collection_2026-27.xlsx, Settlement-of-IGST-to-State-2026-2027.xlsx, ewb-data-2026-27.xlsx, Gross_Net_Tax_collection.xlsx, REGISTRATION.xlsx; one file per FY back to 2017-18). XLSX downloads returned 200 here and from check-host nodes in the US, Germany and India. The GSTR-3B sheet gives, per state, taxpayers eligible to file, filed by due date, filed after due date and total returns. Annotate GSTR-1 and GSTR-3B deadlines with real on-time filing rates by state and month; registration counts as context.
CBDT Direct Taxes Data (time series, collection updates, ITR and PAN statistics) Central Board of Direct Taxes, Income Tax Department PDF, HTMLrestricted Unknown 403 Akamai 'Access Denied' (403) here for both the new Liferay URL /direct-taxes-data and the old /Pages/Direct-Taxes-Data.aspx (the apex host 302s to www). check-host.net: 200 from Los Angeles, Dallas, Vancouver and Singapore nodes but 403 from Germany and a Mumbai datacenter, so blocking follows IP reputation rather than country and GitHub runners may or may not pass. Content is PDFs only, for example /documents/d/guest/final-time-series-data-pdf and 'Direct Tax Collections for F.Y. 2026-27 as on ...' notes. Background only (advance-tax collection snapshots around 15 June, 15 September, 15 December and 15 March).
Open Government Data (OGD) Platform India - catalog, search and backend JSON National Informatics Centre (NIC), Ministry of Electronics and IT HTML, JSON, CSV, XLSXrestricted GODL-India 503 Every path tried (home, /search?title=holiday, /Godl, resource pages, /backend/dmspublic/v1/search JSON) returned an Akamai 503 'Reference #102' error page from this Canadian host. check-host.net nodes got 503 from Los Angeles, Dallas and Singapore and 403 from Germany, London, New York and a Mumbai datacenter node, so the portal also refuses datacenter traffic inside India. TLS chain verifies. Internet Archive captures in 2025-2026 are a mix of 200 and 403. Dataset discovery only. No current central-government holiday list, bank holiday list, LLP master or EPFO payroll resource was found (checked the archived catalog index and public code that calls the API); the tax datasets found are one-off Rajya Sabha answer tables.
State/UT-wise Direct Tax Collection 2022-23 (resource e3b6c58c-0292-4b1b-b39a-8388a0d4a35b) Ministry of Finance via OGD Platform India (Rajya Sabha Session 262, Unstarred Question 232, answered 5 Dec 2023) CSV, JSON, APIgeo-blocked GODL-India 503 Catalogue URL re-probed at build: GET 503; text/html; 282 B transferred; HTML, 216 chars of visible text.

No., State/UT, Gross Collection, Refund, Net Collection. No maintained CBDT direct-tax time series exists on data.gov.in; CBDT's own PDFs are on incometaxindia.gov.in (see ogd-cbdt-direct-taxes-data). API connect timeout from here. None.

Earlier check by the survey (status 0, may refer to a related endpoint): Resource uuid read from an archived resource page (April 2024). No EPFO monthly payroll resource was found on data.gov.in; EPFO's payroll PDFs live on epfindia.gov.in (see ogd-epfo-payroll). API connect timeout from here. None.
EPFO payroll data (monthly provisional payroll PDFs) Employees' Provident Fund Organisation PDF, HTMLgeo-blocked Unknown 403 epfindia.gov.in 301-redirects to www.epfo.gov.in, which serves a CloudFront 403 'Request blocked' page here, including for a direct payroll PDF; check-host.net nodes in the US, UK, Germany and Singapore also got 403, while the Mumbai node reached the origin (404 for this old page path, so the listing URL has changed). The Internet Archive fetched these PDFs with 200 in late 2025. None directly; EPF due dates (ECR filing and payment by the 15th) come from the regulatory slice.
MoSPI eSankhyiki portal, JSON API and MCP server Ministry of Statistics and Programme Implementation (MoSPI) JSON, API, HTMLopen Unknown (MoSPI asks for attribution 'Source: MoSPI'; no explicit open licence found) 200 Unauthenticated JSON at https://api.mospi.gov.in/api (for example /cpi/getCpiBaseYear, /rbi/getRbiIndicatorList, /wpi/getWpiBaseYear) answered 200 here; the portal also publishes llms.txt, ai-catalog.json and an MCP server at https://mcp.mospi.gov.in (tools list_datasets, get_indicators, get_metadata, get_data). TLS trap: api.mospi.gov.in needs legacy TLS renegotiation, and OpenSSL 3 clients (Python here, and check-host nodes in the US, Germany and India) fail with 'unsafe legacy renegotiation disabled', so stock Ubuntu runners will fail; it worked with Python ssl.OP_LEGACY_SERVER_CONNECT. Windows Schannel curl was unaffected. Optional context such as CPI release dates or index values; not a source of compliance due dates.
State/UT-wise Gross GST Collection 2020-21 to 2024-25 (resource 5d0b81aa-d513-4dfd-9f57-84571829c049) Ministry of Finance via OGD Platform India (Rajya Sabha Session 266, Unstarred Question 881, answered 3 Dec 2024) CSV, JSON, APIgeo-blocked GODL-India 503 Catalogue URL re-probed at build: GET 503; text/html; 282 B transferred; HTML, 216 chars of visible text. Earlier check by the survey (status 0, may refer to a related endpoint): Resource uuid read from an archived copy of the resource page (October 2025); catalog 'Answers Data of Rajya Sabha Questions Session 266' (78889f83-0f96-484b-9fbc-5be92454446f). API connect timeout from here; a sample-key call returned 200 from the check-host Mumbai node. Typical of GST data on data.gov.in: parliamentary-answer snapshots, not a maintained series. None; the GST portal's monthly statistics workbooks (ogd-gst-statistics) are fresher and reachable.
GST Council website - GST revenue page GST Council Secretariat HTML, PDFopen Unknown 200 Drupal site reachable from outside India; the revenue page links a handful of 2023 PDFs (a monthly revenue note, newsletters, early GST discussion papers). Not a live statistics source. Not for statistics; the same site's Council meeting recommendations matter for the regulatory feed (other slice).
NITI Aayog National Data and Analytics Platform (NDAP) NITI Aayog JSON, CSV, XLSX, APIlogin GODL-India (portal cites NDSAP and GODL; attribute the source ministry) 200 React shell on CloudFront; backend https://loadqa.ndapapi.com. Anonymous GET /v1/search/catalogue?query=gst returned 78 results when sent with Origin and Referer https://ndap.niti.gov.in; without those headers it answers Message 'Invalid Request', which is what the probe recorded. Dataset detail and download calls (POST /v1/dataset/details, /v1/dataset/download) answer 'Token Required' (Cognito login), and the open API (/v1/openapi/getdetails) needs an API key from a registered account. Collections include GST Statistics (returns, registrations, collections, e-way bills) and the MCA Monthly Information Bulletin; nothing on holidays. Background statistics only (GST registrations and returns, monthly company registrations); no due dates.
RBI Database on Indian Economy (DBIE) Reserve Bank of India HTML, XLSX, CSVopen Unknown (RBI asks users to credit 'Database on Indian Economy, Reserve Bank of India') 200 Angular single-page app (8 KB shell, no content without JavaScript); data calls go to /CIMS_Gateway_DBIE/GATEWAY/SERVICES and related gateways with client-side crypto, and no documented public API was found. Reachable from outside India. Low: reference rates or policy-rate history for context; RBI due dates come from RBI notifications (regulatory slice).

Earlier check by the survey (status 0, may refer to a related endpoint): Resource id and the sibling services-only resource c3dfe7e6-0cfd-4ddb-8f79-9cb3695d9866 come from open-source projects that called the API in 2026 (788 rows: state_name, state_id, district_name, lg_dt_code as an LGD district code, micro, small, medium, total; catalog uuid 0536e86e-3751-4054-84e5-e257d4c94477). API connect timeout from here; a sample-key call returned 200 from the check-host Mumbai node. Context only (MSME density by district); adds no dates.

Forthcoming results, announcements and other market data (if reachable).
e-Filing API specifications (ERI and third-party APIs) Income Tax Department - e-Filing portal HTML, PDF, APIrestricted Unknown - GoI website 200 GET 200; text/html; 28 KB transferred; HTML, 7248 chars of visible text. Public page listing the API specification documents. Documents the APIs open only to registered e-Return Intermediaries; explains why PAN-level data stays out of scope for a public static site.
API Setu - Government of India API directory National e-Governance Division (NeGD), Ministry of Electronics and IT JSON, YAML, HTML, APIrestricted Proprietary (API Setu terms of use; OpenAPI specs are public) 200 Next.js directory; its search JSON (/api/list?q=<JSON>) works after fetching one-time headers from /api/auth/generate-headers. Compliance-relevant listings: GSTN Tax Payer Details API v1/v2 (GET /gstn/v2/taxpayers/{gstin}) and GST registration certificate (OTP flow); Income Tax Department Organization PAN Verification API (POST /verify/v1/pan/org) and Track PAN; MSME Udyam Certificate and EPFO UAN Card as DigiLocker document pulls that need the holder's consent. No MCA company-master, eCourts or CBDT statistics API is listed. Specs sit on cf-media.api-setu.in (gstn-v2.yaml: server https://apisetu.gov.in, headers X-APISETU-CLIENTID and X-APISETU-APIKEY). Shows which official verification APIs exist; none can be called from a public static site.

From the check-host Mumbai node the documented sample key 579b464db66ec23bdd000001cdd3946e44ce4aad7209ff7b23ac571b returned HTTP 200, a bogus key 403 and no key 400, so the sample key is accepted from India. A made-up resource id also returned 200, so a 200 alone does not prove a resource exists. Open-source projects report the sample key caps responses at 10 records and is rate-limited (HTTP 429); personal keys need a data.gov.in account. Indirect only: entity enrichment (MCA company master) and context statistics. Nothing date-critical depends on it.
