With recent changes in the IRS tax code, many of us can no longer itemize our expenses & are forced to take the standard deduction which limits all taxes paid to $10,000, which is about half of what most of us pay. Yearly mandatory withdrawals from tax–deferred retirement accounts, called Required Minimum Distribution (RMD), start in the year that you reach the age of 73. The amount of your current year RMD is based upon the value of your IRAS as of December 31st of the prior year. Then the appropriate Uniform Lifetime Table will give you the divisor needed to determine your current year RMD requirement. RMDs must be taken by Dec 31 each year. Check with your financial advisor regarding inherited retirement accounts withdrawals. 

If you want to lower your taxable income, consider donating your Required Minimum Distribution (RMD) to charity. A Qualified Charitable Distribution (QCD) is a direct transfer of money from your IRA to an eligible 501(c)(3) charitable organization and will satisfy your IRS requirement to document tax deductable donations. The great thing about a QCD is that it reduces your reported 1099–R RMD income dollar for dollar. If you don’t take the RMDs from your account, you will be subject to a penalty equal to 25% of the amount that should have been withdrawn. As you check out the IRS Uniform Lifetime Tables to help determine your RMD, you’ll soon realize that your RMD gets bigger with each passing year. So let’s donate to our causes, like SCTA, instead of to Uncle Sam. 

YouTube has lots of help to sort out individual RMD issues:
