This statement is not accurate. Open IRS web-site.
If you cut ONE check for $ 250.00 or more – you need a receipt for it
If you cut a FEW checks for the same organization for total amount of $ 250.00 or more – you don’t need a receipt for each check or for the total amount of money you gave to this organization during the year. Every check treated as a separate donation.
