The rules for required minimum distributions can vary for different types of accounts. By Kimberly Lankford, Contributing Editor September 22, 2015 I know you have to calculate your required minimum distribution from each traditional IRA separately and that you can take the money from any of your IRAs. But can you take the money from your spouse’s accounts? Are the rules different for other types of retirement plans?See Also: Retirees, Avoid These 5 Costly RMD Mistakes IRAs, 401(k)s, 457s and 403(b)s are all owned individually, so even if you file a joint tax return, you must calculate the required amounts based on your accounts and withdraw the money from your accounts, too. RMD Rules for IRAs The calculations for traditional IRAs are slightly different than they are for employer plans. As you’ve pointed out, required minimum distributions must be calculated separately for each traditional IRA, but you can withdraw the money from any of your traditional IRAs. If your wife is also over age 70½, she must calculate the RMDs for each of her traditional IRAs separately, and she can take the money from any of her traditional IRAs. RMD Rules for 401(k)s and 457 Accounts With 401(k) and 457 accounts, you must calculate the withdrawal and take the required amount from each plan separately. However, you generally do not have to take RMDs from your current employer’s plan as long as you’re still working for that employer, unless you own 5% or more of the company. See RMD Rules for Older Workers for more information. RMD Rules for 403(b) Plans The rules are slightly different for 403(b) plans. An employer may give you the option to invest with several financial institutions within one 403(b) plan. You must calculate your RMD across all of your accounts within that employer’s 403(b) plan, but you can take the money from any of your accounts in that employer’s plan. Maura Cassidy, director of retirement products for Fidelity, gives this example: “If you work for one university and have part of your 403(b) with vendor A and part with vendor B, you could withdraw the money from either or both to make the full required amount.” For more information about RMDs for all kinds of accounts, see our Required Minimum Distributions special report.
