Section 80G Deduction – Complete Guide to Tax Benefits on Donations

Section 80G rewards philanthropy with genuine tax savings, but the benefit varies dramatically depending on which of four donation categories your specific charity falls into — a distinction many donors overlook until they discover their expected deduction was only half what they assumed. Understanding these categories, the payment mode restrictions, and how the tax saving actually differs between individuals and companies helps you donate strategically.

• What Section 80G covers and who qualifies
• The four donation categories explained with examples

• Why the same donation saves companies more tax than individuals
• Registration validity — what donors should verify

Section 80G of the Income Tax Act is a provision that allows taxpayers to claim deductions on donations made to eligible charitable institutions and funds, applicable to individuals, companies, HUFs, and firms. Its purpose is to incentivise philanthropy and support organisations engaged in social, cultural, or economic development activities.

To claim relief under this section, donations must go to government-approved organisations carrying a valid Section 80G registration number, which must appear on your donation receipt. If the charity's registration has expired at the time of your donation, you cannot claim the deduction — making it essential to verify registration validity before donating.

1. 100% deduction, no qualifying limit: The entire donated amount is deductible with no cap. Applies to funds like the National Defence Fund, PM's National Relief Fund, Swachh Bharat Kosh, Clean Ganga Fund, National Children's Fund, and Armed Forces Welfare Funds.
2. 50% deduction, no qualifying limit: Half your donation is deductible, still without any income-based cap. Covers memorial and disaster relief funds like the PM's Drought Relief Fund, Indira Gandhi Memorial Trust, and Rajiv Gandhi Foundation.
3. 100% deduction, capped at 10% of adjusted gross total income: Full deduction, but limited by your income. Covers donations for family planning promotion and contributions to the Indian Olympic Association or recognised Sports Federations.
4. 50% deduction, capped at 10% of adjusted gross total income: The most restricted category — covers donations to local authorities, public charitable trusts, approved NGOs, notified historic religious places, and housing/urban development authorities.

Category 3 example (100% deduction, income-capped): If your adjusted gross income is Rs. 5,00,000, your maximum deduction is Rs. 50,000 (10% of income) — even if you donated more, the excess simply cannot be claimed.

Category 4 example (50% deduction, income-capped): If your adjusted gross total income is Rs. 6,00,000 and you donated Rs. 50,000, your deduction is the lower of Rs. 25,000 (50% of donation) and Rs. 60,000 (10% of income) — so you can claim Rs. 25,000.

• Donation receipt: Official receipt with donor details, donation amount, and the charity's Section 80G registration number
• PAN card: For identity verification
• Charitable institution details: Name, address, and registration details of the recipient organisation
• Proof of payment: Bank statements or transaction records confirming the mode of payment
• Form 16A (if applicable): TDS certificate issued by the charitable organisation
• Self-declaration form: Required specifically for cash donations

Not all payment methods qualify for the deduction:

• Cash donations: Maximum Rs. 2,000 is eligible for deduction — any amount paid in cash above this threshold does not qualify
• For donations above Rs. 2,000: You must use cheque, demand draft, or digital methods — net banking, UPI, or credit/debit cards
• Donations in kind: Items like food, clothes, or medicines do not qualify for deduction under Section 80G — only monetary donations are eligible

This is a genuinely counter-intuitive but important point: two taxpayers donating the identical amount can end up with meaningfully different tax savings, purely based on their tax structure.

Worked example: Mr. A (individual) and M/s. Z Pvt. Ltd. (company) each donate Rs. 1,00,000 to an NGO eligible for 50% deduction with a 10% income limit, both with Rs. 6,00,000 total income under the old regime.

Mr. A pays tax based on slab rates, saving Rs. 10,400. M/s. Z Pvt. Ltd., taxed at a flat 30% corporate rate, saves Rs. 15,000 from the identical Rs. 50,000 deduction — the benefit depends not just on how much you donate, but on your applicable tax rate.

NGOs and charitable trusts must be registered under Section 80G to offer donors tax benefits, and this registration isn't permanent. Organisations first receive provisional registration valid for 3 years, after which they must apply for permanent registration valid for 5 years, renewable every 5 years thereafter.

Beyond registration status, it's worth understanding that the government periodically updates the list of approved institutions and can add or remove specific funds from eligibility. This means an organisation that qualified for 80G benefits in a previous financial year isn't automatically guaranteed the same status going forward — checking the Income Tax Department's current notifications before making a significant donation, particularly to lesser-known local charities, protects you from claiming a deduction that later gets disallowed during assessment.

Special note for Section 8 companies: If your chosen organisation is a Section 8 company (a not-for-profit entity under the Companies Act), its 80G registration required renewal by March 2025 to continue offering benefits from April 2025 onward — worth confirming current registration status directly before donating to any such entity.

Section 80G donations work alongside other deduction sections — including Section 24(b) for home loan interest — as part of a comprehensive old-regime tax strategy. If you're planning a property purchase alongside your charitable giving, a home loan from Bajaj Finance can complement your overall tax planning.

Bajaj Finance offers home loans from 7.25% p.a.* with amounts up to Rs. 15 Crore* and tenures up to 32 years. Check eligibility today.

Section 80G offers genuine, meaningful tax savings for charitable giving, but understanding which of the four categories your intended donation falls into — and following the payment mode rules precisely — ensures you actually receive the deduction you expect.
