Lets Break It Down
In 2009 an employee is allowed to contribute $16,500 to his or her 401K. In 2010 the amount could go up, based on inflation. But if you turn 50 in 2009 you can contribute an extra $5,500 for a total of $22,000. In 2010 persons age 50 or older may be able to contribute even more, depending on the effects of inflation.
At the same time that working individuals are contributing to their future retirement, employers can also contribute. Employers may contribute as much as 6 percent of a workers gross pre-tax compensation. For example, if a worker receives $100,000 a year in compensation, the employer may contribute as much as $6,000 to that employees 401K plan.
That would cap the 2009 total permissible tax-deferred contribution for a worker 49 years of age or less with a gross annual compensation of $100,000 to $22,500 and a worker 50 or older to a maximum contribution of $28,000.
If You Are a Highly Compensated Employee Contribution Limits Can Be Trickier
Employees who make more than $110,000 in a calendar year may be subject to special rules and special limits to the contributions that they and their employer can make to their 401K plan. Under current rules, a Highly Compensated Employee and their employer can contribute no more than 125 percent of the average amount that non Highly Compensated Employees at the same company contribute to their 401Ks.
However, there's a significant twist. A Highly Compensated Employee can contribute more than 125 percent of the average contributions of non Highly Compensated Employees, but anything above the 125 percent threshold must be declared to the IRS and taxes must be paid on that portion of the contribution.
Contributing More To Your 401K
The contribution limits cited earlier in this article only apply to tax-deferred contributions. Workers are allowed to contribute more to their 401Ks, but additional contributions are not tax-deferred. Even taxable contributions have their limits. In 2009 the maximum contribution that can be made, both tax-deferred and non tax-deferred, cannot exceed $49,000.
This amount is subject to inflation indexing and could rise in coming years based on inflation.
