The benefit will therefore be determined by the recipient organization, the nature of the contribution, the deduction percentage that might apply and any specified maximum (qualifying) limit. All donations are not treated alike. There may be some qualified donations that are eligible for deduction at a certain percentage without a qualifying limit while others may have a limit based on adjusted gross total income. Taxpayers should therefore be sure to verify if the category of their contribution is the correct one, instead of taking it for granted that all contributions will be eligible for the same levels of deductions. The type of payment is also important. Some of the cash donations exceeding the prescribed limit may not be eligible for deduction while cash donation via banking or any other acceptable method will likely offer more documentation. The donor should keep the donation receipt and supporting documents for the year of the donation. If the institution is charitable then details they may provide will also be relevant when filing the income tax return, if applicable. It's equally important from the organisation's standpoint and requires appropriate documentation. If an institution wants to register for 80g, it should be aware that it has compliance obligations in respect of the donor related benefits.
