donations, pay taxes, makes a ton of sense to pay 2 years of donations in 1. Its all because the new tax law changed the Standard deduction to $24k/ year. This allows you itemize one year, deducting beyond the $24k one year (with 2 years of donations), then take the standard deduction the 2nd. Saves a certain population several thousand $$
If you can't write the check for 2 years at once, just save up your 2019 donations, pay in 2020, then pay your 2020 donations as you normally would...magic...2 years paid in one.
