Don't Forget to Make Your Retirement, HSA Contributions by the Tax Day Deadline

By Alert Investor Markets Fool.com

Now that we're well into 2017, 2016 may seem like a distant memory. But you shouldn't be too quick to let go of the past year -- at least not until you've maxed out your tax-advantaged retirement and healthcare savings account contributions.

For several tax-advantaged accounts, the contribution deadline isn't Dec. 31, as you might expect, but rather the tax filing deadline. This year, that is Monday, April 18 -- three days later than the traditional deadline of April 15, to accommodate the Emancipation Day holiday in the District of Columbia.

For some tax filers and savers, "a few extra days are going to be helpful," said Ken Tumin, the founder and editor ofthe websiteDepositAccounts. What may also be helpful is that, when it comes to tax-advantaged retirement contributions and HSA contributions, little has changed since last year.

"The changes regarding retirement plan contributions that were made from tax year 2015 to 2016 were super modest," said Mike Piper, a certified public accountant who runs the investing blog Oblivious Investor. "The changes that would affect most people would probably just be the changes to the income thresholds."

Let's take a closer look.

Individual retirement accounts (IRAs)

Individual retirement accounts, or IRAs, allow workers to make tax-advantaged contributions to save for retirement. More than one-third of American households owned IRAs last year, according to research by the Investment Company Institute.

For 2016, as with 2015, anyone under the age of 50 can contribute up to $5,500 to IRA accounts per year. That's total, meaning if you have both a Roth IRA and traditional IRA account, you could contribute a combined $5,500 to the two accounts, not $5,500 to each. Those aged 50 or older may contribute up to $6,500. But people of all ages face a second ceiling: Contributions can't exceed your taxable income.

In addition, if you own a traditional IRA and are covered by a retirement plan through your employer, depending on your income, you may not be able to claim a tax deduction for the full amount of your IRA contribution. To figure out what, if any, deduction you can claim, check out the table provided by the IRShere.

Individuals have until the tax filing deadline to open and make 2016 contributions to traditional and Roth IRA plans, even if you can't take a deduction for those contributions. Read more about IRAs, including the differences between traditional IRAs and Roth IRAs,here.

Self-employed retirement accounts

In the case of self-employed retirement plans, several deadlines have already passed, but here are some instances in which the tax filing deadline still applies:

Solo 401(k)s:If you opened a solo 401(k) account during the 2016 calendar year, you may make 2016 contributions to it until the tax filing deadline.

SIMPLE IRAs:If you opened a SIMPLE IRA account by Oct. 1, 2016, you may make 2016employercontributions to it until the tax filing deadline. The deadline for making employee contributions has already passed. (Learn the difference between SIMPLE IRA employee and employer contributionshere.)

SEP IRAs:You can both open and make 2016 contributions to a SEP IRA until the tax filing deadline.

Health savings accounts (HSAs)

A health savings account is a tax-exempt account that allows individuals and families with high-deductible health plans to pay forqualifying medical expenses.

Contributions to HSA accounts are tax-deductible, and earnings in HSA accounts grow tax-free. For 2016, the IRS limited HSA contributions to $3,350 for individuals (which is unchanged from 2015) and $6,750 (up $100 since 2015) for families. Would-be HSA account holders have until the tax filing deadline to open and fund an account and claim their contributions as tax deductions for 2016.
