From a financial planning standpoint we can infer some reasonable assumptions:
Such a 59 1/2 year old with a substantial IRA has engaged in reasonable planning and prudence in order to place that money where he/she did, and resist taking it out earlier at a penalty.
Please note that 59 1/2 is the minimum age when normal distributions may be made. In fact, boomers have had access to their money through techniques like five year averaging, and annuitized distributions without penalty for quite some time.
Because of this we can expect that there will be no great rush on the money. It’s been available. If the boomer in question is still working and receiving other income they may not wish to begin distributions as those will be taxable at the same rate as their other income (if it doesn’t bump them into a higher rate.)
Sine the assets in an IRA grow tax deffered, they are among your most valuable assets from an investment stanpoint. They get to compound without having taxes drawn off, whether they be taxes on dividends, or capital gains. There is no fear of selling appreciated assets in an IRA either.
Because of all these factors, it is unlikely that a prudent financial plan will involve distributions at an early age regardless of eligibility. The tax defferal is too big an advantage to be given up. For the most part, we can assume that significant retirement assets will be allowed to compound until minimum distributions must occur, which is the year following the year in which a party turns 70 1/2.
In many cases people at age 70 1/2 today are opting to “stretch” their IRAs (taking out even smaller distributions by naming a young beneficiary and basing the distribution on the joint life expectency actuarial table,) in order to take out as little as possible and avoid taxes.
Their is one major caveat to what I’ve said. An IRA is typically a lousy asset to die with in a large estate. The entire sum gets taxed twice at death. For example, if you have a $500,000 IRA and no stretching occurs, upon death that full amount must be withdrawn and income taxes must be paid Then, assuming the estate is large enough, it is also taxed federally through the estate tax. That rate begins at 55%. Combine that with the income tax and local taxes and it’s easy to get deceased IRAs getting taxed at 90% or more of their value.
Deferal is always key, but part of any good plan is preserving assets from this kind of extreme taxation.
So, to answer your question, it is unlikely that there will be any discernable effect in tax revenues because:
- The ability to take distributions without penalty pre 59 1/2 has been available for several years.
and
- Taking distributions early in retirement is generally undesirable due to investment, taxation, and estate issues.
Hope that helps.
