How to Get Proof for an ELSS Tax-Saving Investment?

• To claim a deduction under Section 80C (now Section 123) a valid proof of your ELSS investment is required.
• A Consolidated Account Statement (CAS) or mutual fund account statement for the current financial year is the primary document accepted by employers and tax authorities.
• You can download your CAS instantly from CAMS, KFintech, MF Central, or through their demat account provider using PAN and registered contact details.
• Most employers require the ELSS investment proof by the end of January, while the legal deadline for claiming the deduction is linked to the ITR filing due date.
• If you buy ELSS through an advisor or distributor offline, you can request an official account statement from the fund house.
• If you buying online directly through a fund house or investment platform, you can use the official emailed account statement as valid proof.
• ELSS investments held in a demat account require an account statement issued by the depository participant or generated through CAMS.
• The new tax regime does not allow deductions for ELSS. As such, no proof is needed if you file your returns under the regime.

Under Section 80C (now Section 123) of the IT Act, ELSS funds are eligible for a tax deduction of up to ₹ 1.5 lakhs if you opt for the old tax regime; this deduction is not available under the new tax regime, which is now the default option. But just like all other investments eligible for the 80C benefit, taxpayers should submit valid proof of their ELSS investment to take advantage of the deduction. Take a look at how you can get ELSS mutual fund investment proof.

• The document that income tax officials and employers actually accept as ELSS proof is your Consolidated Account Statement (CAS) or a mutual fund account statement covering the financial year (1st April to 31st March).
• A CAS is a single, SEBI-mandated statement that pulls together all mutual fund folios linked to your PAN, issued by the registrars CAMS or KFintech (or by NSDL/CDSL if you hold funds in a demat account).
• You don't have to wait for it to arrive by post or email; you can generate it on demand from the CAMS, KFintech, or MF Central website using your PAN and registered email or mobile number.
• If your employer asks you to declare this investment, you'll do it through Form 124 (this form replaced the older Form 12BB from 1st April 2026). Whichever form your employer uses, it needs three details from your proof: the ELSS folio number, the amount invested, and the fund house's name; so make sure your CAS or account statement clearly shows all three before you submit it.

Most employers ask for your investment proof by the end of January, so they have time to finalise it before running your February and March payroll and issuing your TDS certificate. This is a company-set window, not a legal deadline, so always check your employer's exact cut-off date. The date that actually matters by law is your ITR filing deadline: for salaried taxpayers (ITR-1/ITR-2) filing for FY 2025-26 (AY 2026-27), that's 31st July 2026, with a belated return still possible up to 31st December 2026 if you miss it. Filing late can also mean losing the option to choose the old tax regime, so it's worth not leaving your proof or your return to the last minute.

• Step 1: If you have invested in an ELSS fund through an advisor or mutual fund distributor, you can contact them for your investment proof.
• Step 2: After receiving your request, the advisor/distributor will then inform the same to the fund house, which will then send you the account statement to the registered address through post.
• Step 3: If you are a salaried employee, you can then submit this account statement to your employer for claiming the 80C (now Section 123) deduction.

• Step 1: If you have invested in ELSS on your own through an online portal or the official website of the fund house, you can easily generate the investment proof online.
• Step 2: Most fund houses regularly send you the account statement through email. These account statements could be considered legitimate investment proofs.
• Step 3: Note that the account statement must be printed on the official letterhead of your fund house. So, the account statement that you can access by logging in to your mutual fund account might not be considered valid proof, as it is generally not printed on the letterhead of the fund house. Account statements received through email are a better option.

• Step 1: If you've invested in an ELSS tax-saver fund through your Demat account, it will be the depository participant and not the fund house that will send you the account statement.
• Step 2: The depository will email you the account statements at regular intervals.
• Step 3: You can also visit the official website of a repository like CAMS and generate the account statement on your own.

No, if you're under the new tax regime, you don't need to submit ELSS proof at all, because Section 80C (now Section 123) isn't available there. The new regime is now the default, so unless you actively choose the old regime, no 80C (now Section 123) deduction applies, and there's nothing to prove. You can still hold and continue investing in ELSS for its return potential and shorter lock-in; it just won't reduce your tax bill unless you opt for the old regime and submit the proof described above.

Higher long-term return potential, shorter lock-in, and the SIP option are some of the top reasons that make ELSS mutual funds one of the best 80C(now Section 123)-eligible investments under the old tax regime. If you have yet to claim the entire ₹1.5 lakh deduction under Section 80C(now Section 123), do consider one of the top ELSS funds not just to save taxes but also to get closer to your long-term financial goals. Consider factors such as your investment tenure, risk appetite, and the reputation of the fund house to select an ELSS that could deliver the expected benefits in the most hassle-free manner.
