Should I Do A Traditional Or Roth 401k?

If your 401(k) or 403(b) retirement plan accepts both traditional and Roth contributions, you have two ways to save for your retirement. Both offer federal income tax advantages. Traditional accounts provide a tax break now. Traditional contributions are not taxed at the time of investment. Instead, taxes are paid on withdrawals, including any earnings. Getting a tax break at the time of investment will leave more money in your pocket now — money that you can invest, save or spend. Roth accounts provide a tax advantage later. Roth contributions are made with money that’s already been taxed, so you won’t have to pay taxes on qualified withdrawals, including earnings.

The conventional approach is to compare your current tax bracket with what you think it will be in retirement, which would depend on your taxable income and the tax rates in place when you retire. If you expect it to be lower, go with pre-tax contributions. If you expect it to be higher, go with the Roth. If you’re not sure, go with both.

However, there are a couple of other factors that are often overlooked. One has to do with the way that the tax code is structured. When you contribute to a retirement plan, you’re contributing money that would normally be taxed at your marginal tax rate. However, when you withdraw money in retirement, some of the money is likely to be taxed at some of the lower tax brackets.
