Traditional and Roth IRA contributions remain unchanged at $6,000 or $7,000 if you are 50 or older.
You may contribute $19,500 to an employer sponsored retirement account, i.e. 401(k), 403(b), or SAR-SEP ($26,500 if you are age 50 or older). Remember, to be eligible for the catch-up allowance, you need to turn 50 this calendar year. If you are 49 now, but turn 50 in November, you are eligible for the full catch-up provision for the entire year.
A break down of changes are as follows:

The defined contribution plan limits (401(k), 403(b)) increases from $56,000 to the lesser of $57,000 or 100% of compensation (this includes employee and employer contributions).
We’re a big fan of Health Savings Accounts here at WealthPoint as they are often triple-tax advantaged. See Josh Bentz’s post on why we think you should invest your HSA for retirement and pay for healthcare expenses out of current cash flow: https://wealthpointadv.com/why-you-should-care-about-health-savings-accounts-hsas/

Lastly, the income phase-out range for making Roth IRA contributions has increased. Taxpayers with modified adjusted gross income (MAGI) under the lower end of the ranges shown below can make a full Roth IRA contribution. If you are in the range, you will only be able to contribute a portion of the $6,000 max. These limits do not apply to making Roth 401(k) contributions, if your employer allows it.

If you plan to save the max to your employer sponsored plan this year, be sure to review and potentially change your payroll deferral percentages. Also, if you turn the big 5-0 this year, don’t forget about the catch-up provisions.
Happy New Year and Happy Savings!
