If your company offer a 401(k) retirement plan program, it would be good idea to take advantage of it and boost your contributions.

Your company's 401(k) will likely offer a selection of investment options, generally mixes of various mutual funds or index funds. 

A plan that consists of a general index fund designed for employees retiring in a certain year range will probably have lower fees than an actively-managed equity fund, for instance.

However, employees who want to have a more active role in their portfolio may be able to choose more targeted funds (technology stocks or U.S. long-term government bonds, for instance).

Even if you're self-employed, you can potentially take advantage of a solo 401k to both lower your taxable income and save for retirement. If you don't have a solo 401k plan yet, check out the best places to open a solo 401k.

Solo 401k Contribution Deadlines

If you're looking at this contribution limits for a solo 401k, it's important to note that you also are required to contribute by certain deadlines.

The solo 401k has two sets of deadlines: the deadline for the employee contribution (i.e. your elective contribution), and the deadline for the employer matching contribution (i.e. what your business puts into the 401k).

For your employee elective contribution, you must make your contribution by December 31, usually. If you're an S-Corp and on payroll, you must elect to make this contribution and have it paid by December 31. If you're a sole proprietorship or single-member LLC, you must still elect to make your contribution by December 31, but your contribution can be made up to the personal tax filing deadline (typically April 15). Sound strange? It is a bit strange, but the nuance is due to the type of tax return you file (S-Corp return versus Schedule C on your personal return).

For your employer contribution, you must make your contribution by the tax filing deadline of your corporation (or personal return if you're filing on a Schedule C). This could be March 15 or September 15 for S-Corps, or April 15 or October 15 for those filing on a personal return.

Note: Due to the coronavirus pandemic, the tax filing deadline was delayed until 7/15/2020. What this means is that you have a little more time to make your solo 401k contributions if needed. The IRS hasn't issued formal guidelines for this, but given the law says "tax filing deadline", it's safe to assume this is the case unless further guidelines clarify this.

Benefits Of Contributing To A 401k

Withdrawals From A 401k Plan

As 401(k) contributions are not taxed as income in the year that the contribution is made (the amount is deducted on the employee's annual income tax returns), withdrawals are taxed instead.

The tax rate that will apply to these withdrawals is the income tax rate that applies to the account owner during the year of withdrawal. This is generally considered advantageous because most people will have lower taxable income during their retirement years than when they worked, meaning their effective tax rate on the amount withdrawn will be lower.

Owners of 401(k)s must be at least 59½ or be completely and permanently disabled to withdraw the funds in their account without tax penalties.

If they are younger than this age, they will pay a 10% penalty tax on the amount withdrawn in addition to owing normal income tax on the amount.

There are several limited exceptions to this 10% penalty, including the employee's death, qualified domestic court orders, and unreimbursed medical expenses that exceed 7.5% of the employee's Adjusted Gross Income.

Finally, account owners must begin making at least required minimum withdrawals, which are set by the IRS using a life expectancy table, when the account owner turns 70½, unless he or she is still employed.

A 50% penalty is applied on the minimum withdrawal if it is not taken for that tax year.
