2018 Solo 401(k) Establishment Deadline

by Clode Moradi, MSPFP, CFP®


There’s lots of confusions about this, so I’m going to give a basic explanation about account establishment, without getting into contribution calculations and how best to set them up. I like to cover that on a case by case basis, instead of putting out generic info.


Deadline for 2018 Tax Year

If you want to make contributions (employee deferral and Profit-Sharing contribution by employer), the Solo 401(k) HAS to be setup by December 31st of 2018. There’s a lot of confusion about this because this is not the case for a SEP Ira and most people think that a SEP and a Solo 401(k) have the same account establishment rules. They do not…


As long as the Solo 401(k) account is set up by December 31, 2018, you can contribute to it for tax year 2018. Your salary deferral contribution will be based on your W2 income (Corp) or profits (Sole Proprietor) from 2018 and the profit-sharing portion comes from the business. Keep in mind that the type of business entity you operate under makes a difference on your allowed profit-sharing contribution amount and needs to be calculated correctly. Also, max allowed contribution limit for both the salary deferral and profit sharing is $55,000 if you are under 50 years of age and $61,000 if you are over 50 years old.


Even though you can contribute your employee salary deferral amount later than December 31st (before tax return deadline), you need to file your W2 for 2018 in a timely manner and specify how much you plan to contribute. Max amount for 2018 tax filing is $18,500 ($24,500 if you are over 50 years old), calculated as a dollar for dollar contribution of W2. Make sure you let your account or payroll company know about this before you do anything else.


If you have any questions or would like to come in for a detailed consult on business tax planning, please call to make an appointment. We have already started planning for the 2019 tax year.
