what is the maximum charitable donations deduction without a receipt?

[AlreadyReadyAlready]

I plan to itemize deductions for tax year 2021.  Can I deduct charitable donations without a receipt?  If so, what is the maximum amount (married filing jointly)?

You are not allowed to deduct any charitable donations without proof of the donation.

If under $500 was given with a credit card, would the credit card statement count as a receipt?

What about this scenario?

The only exception is donations made to organizations that have a dropbox type operation where a receipt is impractical.

No, if the donation is over $250, then you also need written acknowledgment from the charity in order to have sufficient documentation if requested by the IRS.

For further information, take a look at the following TurboTax help article and the link to information provided by the IRS:
