Retirement can open up a whole new way of life for Americans ready to bring their working years to an end, but at least one thing doesn’t change. Uncle Sam continues to direct his gave toward you.

The IRS still keeps a watchful eye on your income, including whatever amount you’re pulling from the IRA or 401(k) that you spent decades building into a nice, hefty nest egg.

Uncle Sam has been waiting for years--possibly decades--to tax that money because the deposits you made were pre-tax, meaning you weren’t taxed on the income you contributed to the accounts. That tax-deferral system works well–until retirement time arrives and you need the money.

When you defer taxes, eventually it catches up with you. Suddenly, your IRA or 401(k) isn’t worth as much as you thought because every withdrawal you make potentially can be taxed. But there’s an answer.

Those traditional IRA and 401(k) accounts can be converted to a Roth IRA, which isn’t taxed when withdrawals are made. That doesn’t mean you’ll avoid the taxes because you’ll pay them when you make the conversion. But when you reach retirement, you’ll be able to make withdrawals the rest of your life tax free.

If President Donald Trump and Congress fulfill a promise to lower taxes for all working-class Americans, you might find an opportunity to save. Be sure to keep an eye on your tax bracket over the next few years so you're ready to take full advantage if tax reform is passed.

He says some facts worth knowing about Roth conversions include:

* Space out the conversion. Most people wouldn’t want to take the tax hit all at once, and you don’t have to. You can transfer the money into a Roth in increments over the course of a few years. So if, for example, you space out the conversion over five years, then the tax is spaced out over five years as well. A few factors determine how much you can convert the first year, but about 40 percent of the people I have worked with were able to convert half of it in the first year.

* The age to do it. A conversion can be done regardless of the account holder’s age, but in my experience people 59.5 to 74 benefit the most.

* Start with a Roth if possible. Some employers now offer a Roth 401(k) as an option. Employees should take advantage of that. They won’t get to defer their taxes on the portion of their income they contribute to the account, but the interest grows tax free and they’ll avoid taxes come retirement time.

I recently did a conversion for a client where he had calculated that if the client lived to be 90, they would have paid nearly $1 million in taxes on IRA withdrawals. Switching to a Roth lowered that to $200,000. Obviously that still sounds like a lot, but I’d rather pay $200,000 than nearly $1 million.
