How Federal Taxes Affect Your Retirement Accounts

With luck you're going to retire one day. With careful planning you're going to retire with substantial amounts of money in your retirement accounts. One of the things that will impact the ultimate success of those retirement accounts is how taxes will affect them. They can take a substantial chunk out of your nest egg, or a much smaller nibble, it's all up to how you, and your tax adviser choose to allocate your resources.

From a tax perspective, there are three broad classes of retirement vehicles; taxable, tax deferred, and tax exempt. Why wouldn't you just stick to tax exempt vehicles and avoid the whole tax issue altogether? Well, you could, and some have, but that limits your choice, and your probable investment return, in the name of federal tax savings. Vehicles such as tax exempt municipal bonds (munis) can offer an attractive option for investors, but typically the level attractiveness rises with the investor's tax bracket. Investors in higher tax brackets will avoid comparatively higher levels of taxation than lower income investors. For these investors, the avoidance of federal taxes may swing the pendulum more in favor of tax exempt investments. In many cases though, tax exempt investments offer substantially lower yield than other choices, and the reduced yield is not sufficiently compensated for by their exempt status.

Many more retirement accounts consist of tax deferred retirement instruments. These include traditional IRAs, 401(k) plans, 403(b) plans (403b plans are for public employees and non-profit private organizations), and Roth IRAs. There are tax differences between these three. The Roth IRA is taxed when the money is earned, but not when it is withdrawn, assuming you withdraw the funds after you turn 59-1/2 years of age. Prior to that age, you'll incur the wrath of the IRS in the form of a 10% penalty, in addition to any taxes you may owe.
Traditional IRAs and 401(k)s are similar in that they use pretax income to fund the plan, and then the retiree / investor is taxed when the money is withdrawn. If you are in lower tax bracket after retirement it is most advantageous to use a traditional IRA. Most people are in lower tax bracket after they retire, because the years immediately preceding retirement are usually the peak earning years. Most people will find that their situation warrants using a Roth IRA plan at the beginning, especially for the first 20 years or so of their contributions, when they are in comparatively lower tax bracket. If your federal income tax rate is the same at contribution and withdrawal, it does not matter when you are taxed. The results will be the same if pay taxes before you contribute, or when you withdraw. If you don't believe me, consider the following:Traditional: Your 1st year $7,500 pretax contribution, invested for 40 years at 8% yield = grows to $162,934. You pay taxes at your income tax rate, as dictated by your taxable income. If you are in the 28% tax bracket (for 2007 = 28% on marginal income between $64,250 - $97,925) and we assume your actual tax rate works out to 22%, you'll lose $36,505 in income taxes on this portion of your distribution, bringing your after-tax distribution amount to $127,088.

Make the same assumptions for a Roth plan and you'll get the following:$7500 – 22% taxes paid before contribution = $5,850 net contribution. $5,850 invested for 40 years at 8% = $127,088. See, I told you so. When it gets murky is when your tax rates are not the same, as is usually the case as your life progresses. You'll want to see a very competent tax and retirement adviser to assist you with your retirement planning so you can maximize your retirement assets and minimize your tax consequences.

NOTE: If you control how much money you take as distributions you can control not only your income tax, but have a very significant effect on how much taxes you on your social security benefits as well.

Which of these is best for you depends upon your specific situation.401(k) plans are company sponsored, while IRAs are private. The big advantages of a 401(k) is that the funding is automatic and comes right out of your paycheck. This can be a huge advantage for discipline challenged savers. The biggest advantage from an investment perspective is that many companies offer to match all, or portion of the employee's contribution. The power of this almost cannot be underestimated. It's really quite powerful, and can contribute substantially to a comfortable retirement. A traditional IRA is similar to a 401(k) for most practical purposes, except that the investor self funds the account and their employer has nothing to do with it.
Traditional IRAs and company sponsored retirement plans have another age requirement. You must begin to take minimum withdrawals (distributions) when you reach 70-1/2 years of age. Roth plans do not have this age restriction, so if you plan on bequeathing one of these to someone, this may be the way to go, as it can sit there, growing, after you're deceased. When the lucky recipient does begin withdrawing the money when the so desire, and pay income taxes on it with no additional penalties.

Traditional and on-line brokerage accounts are examples of non-tax deferred investment accounts. There also are some automatic pans such as Dividend ReInvestment Plans (DRIPs) where the dividends form a company's stock are automatically reinvested in purchasing more stock. With a DRIP, you will pay income tax on the dividends you receive in the year they are received, even if they are immediately reinvested. That is something to keep in mind when considering dividend paying investments that aren't tax deferred.
