Life Expectancy And Required Minimum Distributions
By: MICHAEL RUBIN - June 11, 2018
If you have been saving for retirement throughout your career, you likely understand the tax advantages of IRA accounts, 401(k)s, 457 plans and other tax-deferred retirement savings plans like a Thrift Savings Plan, 403(b), Tax Sheltered Annuity, SEP IRA, or SIMPLE IRA. But transitioning from the "accumulation phase" to the "distribution phase" of retirement requires a special understanding of IRS rules related to when you must begin taking withdrawals from your qualified retirement accounts.
Required Beginning Date for RMDs
Starting on April 1st of the year following the year you reach 70½, you are obligated by law to begin taking your Required Minimum Distribution (RMD) from your 401(k), traditional IRA, or another qualified retirement plan every year. This minimum amount is calculated based on the beginning balance of your combined qualified accounts as of the start of the tax year divided by your life expectancy.
The Required Minimum Distribution Rules
Required minimum distribution (RMD) rules exist because of the tax benefits provided by qualified retirement plans. Those qualified plans like 401(k) plans, traditional IRAs, and SEP IRAs all offer tax deductions on the contributions make (up to a limit) as well as tax-deferred growth on the contributions earnings. These incentives and benefits not only encourage people to save for retirement today but also make exponentially increase the overall growth of those retirement assets for tomorrow.
But, eventually, the IRS will want its share of those dollars.
That's where RMD rules come in. RMDs essentially ensure that the IRS will eventually get to tax the assets in your retirement accounts by requiring that you take distributions that will be added to your taxable income each year. For most retirees, RMD rules have no special impact on how their retirement funds are used, as most retirees start making withdrawals from their account(s) as a means of retirement income before age 70½.
How Required Minimum Distributions are Calculated
Your personal required minimum distribution (RMD) is calculated based upon the beginning balance of all of your qualified retirement accounts combined and you life expectancy. Though many plan custodians will provide your calculated RMD for you, they are not required to, so it is best if you are able to calculate it yourself.
To calculate your RMD for a certain year, you will take the account balances of all of your qualified retirement accounts (401(k), traditional IRA, SEP IRA, SIMPLE IRA, etc.) on December 31st of the previous year and add them together. Then, you will simply divide that total by your life expectancy factor. How do you find your life expectancy factor? You must consult the IRS Uniform Lifetime Table.
Let's assume a single individual turned 70 1/2 in 2018 and had a combined IRA balance of $274,000 on the last day of 2018. As a single individual, this person will use the distribution factor found in IRS Publication 590. The distribution factor will be 27.4 assuming they would still be 70 on the last day of 2018.
Roth IRAs are NOT Subject to RMD Rules
While IRS rules require you take RMDs from Roth 401(k)s, your own Roth IRAs are not subject to required minimum distributions. Inherited Roth IRAs have minimum distribution requirements.
IRS Uniform Life Expectancy Table
To determine your life expectancy factor, the IRS created the following Uniform Life Expectancy Table. Unless your spouse is your sole beneficiary and is more than 10 years younger than you, this is the table to use That said, if your spouse is ten or more years younger than you, use the joint and survivor tables instead.
