Have the limits on charitable deductions changed?
Yes, they have. As part of the bill, donors can deduct 100 percent of their gift against their 2020 adjusted gross income. If you have $1 million of income, you can give $1 million to a public charity and deduct the full amount in 2020.
The new deduction is only for cash gifts that go to a public charity, like Giving Center. If you give cash to, say, your private foundation, the old deduction rules apply. And while the organizations that manage donor advised funds are public charities, you do not get the higher deduction for donating cash to your donor advised fund.
If your assets are substantial enough that you can give more than your income this year, you won’t lose the deduction for the excess amount. You can use it next year, as has always been the case.
