The big reason that somebody would do this is to turn a non-tax-deductible contribution into a tax-deductible contribution.
Ignoring the special charity deduction rules of 2020 and 2021 where a standard deduction tax payer could claim a $300 or $600 charitable deduction, the taxpayer who uses the QCD (Qualified Charitable Distributions) process can have some of their required charitable contributions as non-taxable even if they don't itemize.
Lets say a taxpayer likes to make a $5,000 contribution to their favorite charity. If they send the money from their regular bank account, they can only save on federal taxes if they itemize. But if they have the custodian pull the money from the IRA, and then have the custodian send the money to the charity. The $5,000 counts as part of the required IRA distribution, but it doesn't count as income on their Federal tax forms. It makes it essentially tax-deductible, even though they can't include Schedule A.
Here is an example:
- Married couple, retired, in their mid seventies. So they can do a QCD and must make a RMD of 50K.
- They have State and local taxes of greater of $10,000 so it is capped at $10,000
- They don't have a mortgage, so they can't deduct interest.
- The donate $5,200 to charity.
- They are in the 22% tax bracket.
- Their standard deduction is: $27,800 (both are over 65)
Option 1:
- They take the RMD of $50,0000 and then from their checking account they donate $100 a week to their church or $5,200.
- They can include $15,200 on Schedule A.
- Therefore they take the standard deduction of $27,800
Option 2:
- They take the RMD of $50,0000.
- But they direct $5,200 be sent to their church via the QCD.
- The rest of the RMD $44,800 is sent to their checking account,
- They can include $15,200 on Schedule A.
- Therefore they take the standard deduction of $27,800
- But their taxable income has been reduced by $5,200.
If they tax Option 2, that reduced taxable income saves them :
0.22 x $5,200 = $1,144
But lets say they want to give $25,000. That means they will itemize and their deduction will be $35,000. But if they take the standard deduction and use the $25,000 they reduce their income by (27800+25000) $52,800.
That would save them
0.22 x $17,800 = $3,916
Not bad for 15 minutes of work each year.
So they can save money even if they could have itemized.
But it is a wash if they would have itemized even if they made no charitable deductions.
