What tax documentation will I get?

If you donate using Giving What You Can you will get a receipt for tax purposes.

Receipts for credit card payments should arrive almost instantly, but if you make an offline payment (like a bank transfer), you may not get a receipt until roughly a week or two after we receive your donation. In some cases it could take up to six weeks.

US donors will also get a single tax statement showing their donation history at the end of each tax year.
