Section 80G Tax Deductions: 100% vs 50% Limit, 10% Adjusted Gross Total Income Cap

Section 80G of the Income Tax Act allows a taxpayer to claim a deduction for donations made to eligible charitable institutions and specified funds — but the deduction is neither uniform in rate nor unlimited in amount, and a donor's actual tax benefit depends on correctly classifying which of four distinct categories a particular donation falls into.

1. The Four Categories of 80G Deduction

2. The 10% Qualifying Limit — How It Actually Works

For donations falling in Category C or D (subject to the qualifying limit), the deduction is not simply 50% or 100% of the amount donated — it is capped at 50%/100% of the lower of:

• The actual amount donated, or
• 10% of the taxpayer's Adjusted Gross Total Income (AGTI)

Adjusted Gross Total Income for this purpose is the Gross Total Income reduced by:

• Long-term capital gains taxable under specific sections,
• Short-term capital gains taxable under Section 111A,
• Income referred to in Sections 115A, 115AB, 115AC, 115AD, or 115D (relating to certain non-resident and foreign company income), and
• All deductions under Chapter VI-A other than the Section 80G deduction itself.

Worked example: A taxpayer with a Gross Total Income of ₹20,00,000, no capital gains of the above categories, and other Chapter VI-A deductions (80C, 80D, etc.) totaling ₹2,50,000 has an AGTI of ₹17,50,000. The 10% qualifying limit is therefore ₹1,75,000. If this taxpayer donates ₹3,00,000 to a Category D trust, the deduction is not 50% of ₹3,00,000 — it is capped at 50% of ₹1,75,000 (the lower of actual donation and the qualifying limit), i.e. ₹87,500, not ₹1,50,000.

3. The ₹2,000 Cash Donation Limit

No deduction is allowed under Section 80G for any donation exceeding ₹2,000 if paid in cash. Donations above ₹2,000 must be made through a banking channel — cheque, demand draft, UPI, net banking, credit/debit card, or any other non-cash mode — for the amount above ₹2,000 to qualify. In practice, given how easy digital payment is, most professionally run trusts now decline cash donations above this threshold entirely, or issue receipts explicitly noting that only ₹2,000 of a larger cash donation is 80G-eligible.

4. The Form 10BE Reconciliation — a Mandatory Step, Not Optional Paperwork

Since the Form 10BD/10BE reporting regime came into force, a donor's 80G claim is cross-verified against the donee institution's own Form 10BD filing, reflected in the donor's Annual Information Statement (AIS). Practically, this means:

• A donation receipt alone is no longer sufficient documentation. The donor should obtain and retain the Form 10BE certificate issued by the trust (generated only after the trust files Form 10BD reporting that specific donation), since this is what the tax department's system actually matches against.
• If the trust fails to file Form 10BD, or reports the donation incorrectly, the donor's 80G claim can be flagged for mismatch even though the donation itself was entirely genuine — this makes it worthwhile for a donor making a significant donation to confirm with the trust, closer to year-end, that the donation has been (or will be) correctly reported.
• Donors should check their AIS before filing their return to confirm the donation is correctly reflected, rather than relying solely on the paper receipt from the time of donation.

5. Important Restrictions and Exclusions

• Not available under the new tax regime (Section 115BAC): A taxpayer opting for the default new tax regime cannot claim the Section 80G deduction — this is one of the deductions specifically excluded under the new regime's simplified structure. The deduction remains available only for taxpayers choosing the old tax regime.
• Donations in kind are not eligible. Section 80G applies only to monetary donations — contributions of clothes, food, medicine, or other goods, however genuinely charitable, do not qualify for a Section 80G deduction (though they may be relevant for the trust's own reporting/valuation purposes, not the donor's tax claim).
• The recipient institution must hold valid, current 80G approval at the time of the donation — a donation to an institution whose 80G approval has lapsed or was never granted does not qualify, regardless of the institution's genuine charitable purpose. Donors making substantial donations should verify the institution's approval status (and its validity period, since 80G approvals are now time-bound and require periodic renewal) before donating.
