Today, I'd like to offer a look at what it would take to be in a higher tax bracket at retirement.
Note there is a withdrawal rate of 4 percent that is commonly used as a safe number to avoid spending down your funds too quickly. Further, I assume no itemized deductions, just the standard deduction, to keep this analysis as simple as possible.
In 2012 dollars (and tax brackets) a couple would have a standard deduction of $11,900 plus exemptions totaling $7,600. The first $19,500/year is tax-free. A 4 percent withdrawal means one needs $487,500 in pretax savings to generate that $19,500.
The next $17,400 is currently taxed at 10 percent. Another $435,000 to generate that; $922,500 to just fill the 10 percent bracket.
The next $53,300 is taxed at 15 percent. You need an additional $1,332,500 to be able to withdraw this much.
Let's summarize this, and take a moment to think about these numbers. $90,200 is the total income you can have in 2012 and have that last taxable dollar taxed at 15 percent. If you are taking all of that from pretax accounts, you need $2,255,000 to maintain that withdrawal rate.
I find that a chart is the better way to present so many numbers to clarify this discussion and bring the point home.
|Amount you can withdraw at each rate||Gross Dollars needed to generate this withdrawal||Cumulative dollars needed to 'top off' this tax bracket|
|Married Filing Joint|
All of the numbers presented in the text are now shown above. I've added the 25 percent marginal rate as well as the numbers for a single filer. I use the term "zero bracket" to describe the effect of the standard deduction along with the exemption amount, it should not be treated as an official tax term.
Well-informed readers will note that I've ignored the fact that Some Social Security benefits may be taxable. As this occurs at $25,000 for single and $32,000 joint, it lends itself to a completely different dialog, beyond the scope of this article. Suffice it to say that as one gets closer to retiring, this issue does need to be addressed.
This discussion is focused on just how much income (and therefore wealth) it takes to even retire at the top of the 15 percent tax bracket. It would be a shame to convert money and perhaps pay a marginal rate of 25 percent only to find yourself retiring at a lower rate, as most of us will.
On the other hand, if when you do your taxes for 2012, you realize you are currently in the 15 percent marginal bracket, it can certainly make sense to convert enough each year to "fill the bracket," so your last dollar taxed is at 15 percent, but any higher amounts would have been at 25 percent.
Likewise, the same strategy can be used in any year your income drops for whatever reason, a period of unemployment, a spouse taking time off to raise a child, etc.
Remember, the Roth conversion is not an "all or none" decision. For most converts, it's an annual partial conversion that will maximize their wealth and minimize their tax burden.
