CSR-1 Filing - Register Your NGO to Legally Receive CSR Funds
Since April 2021, any NGO, Trust, Society, or Section 8 Company that wants to receive Corporate Social Responsibility (CSR) funds from a company must first file Form CSR-1 with the Ministry of Corporate Affairs. It's a one-time registration that establishes your NGO as an eligible 'implementing agency' and issues a unique CSR Registration Number, without which companies legally cannot route their CSR budget to you. We handle the DSC-based filing end to end - document preparation, CA/CS/CMA certification of the form, and submission on the MCA portal.

What is Form CSR-1 and why does it matter?
Form CSR-1 is a registration form prescribed under the Companies (Corporate Social Responsibility Policy) Rules, 2014, as amended. It is filed on the Ministry of Corporate Affairs (MCA) portal by an NGO, Trust, Society, or Section 8 Company that wants to act as an 'implementing agency' - an organisation eligible to receive and utilise CSR funds on behalf of a company discharging its Section 135 CSR obligation.
Before April 2021, companies could route CSR funds to NGOs somewhat informally. Since then, CSR-1 registration has been a hard prerequisite: a company can only claim CSR spend if the money went to an implementing agency that holds a valid CSR Registration Number issued after a successful Form CSR-1 filing. In practice, this means an NGO without CSR-1 registration is invisible to corporate CSR budgets, no matter how strong its work is.
The filing itself is straightforward on paper - it captures your organisation's registration details, PAN, key office bearer information, and past CSR-related experience if any - but it requires the Digital Signature Certificate (DSC) of your authorised signatory and must be digitally certified by a practising Chartered Accountant, Company Secretary, or Cost Accountant before submission. Errors or mismatches between the form and your registration documents are the most common reason filings get sent back for correction.
CSR-1 registration vs 12A/80G registration: two different approvals
NGOs sometimes assume having 12A/80G is enough to receive CSR funds - it is not. CSR-1 is a separate, additional registration.

How CSR-1 filing works
Form CSR-1 is filed entirely online through the MCA portal, and requires a valid DSC and professional certification.
Eligibility and document check
We confirm your entity type qualifies (Trust, Society, or Section 8 Company) and review your registration documents, PAN, and 12A/80G status if held.
Digital Signature Certificate (DSC)
If your authorised signatory doesn't already have a valid DSC, we help arrange one - Form CSR-1 cannot be submitted without it.
Form preparation
We fill Form CSR-1 with your entity's details, office bearer information, and registration particulars, cross-checked against your certificate of registration to avoid mismatches that trigger a resubmission.
CA/CS/CMA certification
A practising Chartered Accountant, Company Secretary, or Cost Accountant digitally certifies the form, as mandated by the MCA rules, before it can be filed.
Filing on the MCA portal
We submit Form CSR-1 along with the DSC and certification on the MCA portal and track it through to approval.
CSR Registration Number issued
Once approved, MCA issues a unique CSR Registration Number - this is what you share with companies as proof of eligibility to receive CSR funds.
CSR-1 is a one-time registration - you don't refile it every year. What typically brings people back is an amendment (change of registered office, change of authorised signatory, or a new office bearer) or, for NGOs that never got around to it, doing it now before a CSR opportunity falls through for lack of registration.

Why file CSR-1 through us
Frequently asked questions
Form CSR-1 is a registration form filed on the MCA portal under the Companies (CSR Policy) Rules, 2014, that registers an NGO, Trust, Society, or Section 8 Company as an eligible 'implementing agency' for receiving CSR funds from companies. It results in a unique CSR Registration Number.
Yes, since 1 April 2021, it is mandatory for any entity that wants to legally receive and utilise CSR funds from a company. A company cannot count money sent to an unregistered NGO as valid CSR spend under Section 135.
Registered Public Trusts, registered Societies, and Section 8 Companies are eligible. Unregistered groups or informal collectives are not - they must first register as one of these entity types.
No, holding 12A/80G is not a legal prerequisite for filing Form CSR-1. However, most corporate CSR teams expect implementing agencies to hold 12A/80G as well, so NGOs without it are often at a practical disadvantage even if technically CSR-1 eligible.
It's the unique number issued by MCA once your Form CSR-1 is approved. You share it with companies as proof of eligibility when pitching for CSR partnerships, and it's often requested in CSR grant applications and CSR-linked tender documents.
Yes, Form CSR-1 must be filed using the DSC of your entity's authorised signatory - it cannot be submitted without one. If you don't already have a valid DSC, we can help arrange it as part of the filing.
Yes, the MCA rules require Form CSR-1 to be digitally certified by a practising Chartered Accountant, Company Secretary, or Cost Accountant before it can be submitted - this is a mandatory part of the filing, not optional.
MCA charges a nominal filing fee for Form CSR-1. The exact amount is set by the MCA fee schedule at the time of filing - our professional fee, separate from this, covers preparation, certification coordination, and submission.
Typically a few working days once your documents are complete and your DSC is ready. Delays usually come from mismatched details between the form and your registration certificate, or from arranging a fresh DSC.
No, CSR-1 is a one-time registration. You would only need to refile or amend it if key details change - for example, a new authorised signatory or a change in registered address.
Yes, there's no minimum operating history required by the CSR-1 rules themselves. That said, companies evaluating you for actual CSR funding will typically also look at your track record, so newer NGOs may want to register early and build credibility in parallel.
Most rejections happen due to mismatches between the form and your registration documents, or an invalid DSC/certification. We review and correct the specific issue and refile - there's no penalty for resubmission, just a delay.
No. CSR-1 makes you eligible to legally receive CSR funds - it does not itself connect you with a donor company or guarantee funding. For help with CSR fundraising strategy and being discovered by corporate CSR budgets, see our CSR consultancy service.
No. Form CSR-1 is filed by the implementing agency - the NGO, Trust, Society, or Section 8 Company receiving the funds - not by the company providing the CSR funds.
CSR-1 became mandatory from 1 April 2021 onward. If you continue to receive CSR funds today, you need current CSR-1 registration regardless of your history before that date - we can help you get registered so ongoing and future CSR relationships stay compliant.
