When making a donation to an animal shelter charity, it is important to obtain a receipt or other written documentation from the organization acknowledging the donation. This documentation will serve as proof of the donation when filing your taxes. The amount of the donation that you may be able to deduct from your taxes may depend on your income level and the type of donation.
It's always advisable to consult with a tax advisor or refer to the most up-to-date IRS guidelines to ensure that you are properly claiming any deductions for charitable contributions.
