It’s likely your donation is tax deductible. It all depends on your school’s tax exemption status. So, please double check with your school or parent organization to verify if they are tax exempt.
If your school has an online payment option and you pay online, a receipt will be emailed to the email on file afterward. For cash and check payments, the school can provide you with a handwritten receipt. For contributions less than $250, a cancelled check or a bank record is sufficient documentation.
And remember to hug your local accountant. Taxes are complicated.
