SEP IRA and 401K contribution household wage criteria?

[dmertz]

The deadline for making a SEP IRA contribution for 2017 is the due date of your 2017 tax return.  That's April 17, 2018 if you do not request a filing extension or October 15, 2018 if you do request a filing extension.

I am not a CPA.  I make it a point to know the code and regulations because I and my family have many retirement accounts and I've encountered many representatives of financial institutions who don't know these things.

The October 1 deadline is the deadline for establishing a SIMPLE plan, not a SEP plan.  It makes no sense in this case to have a SIMPLE plan rather than a SEP plan.  Since the individual elective deferral limit of $18k is already maxed out with the 401(k) elective deferrals, no elective deferrals would be permitted to a SIMPLE plan.  Contributions to a SIMPLE plan would be limited to a 2%-of-compensation employer contribution.

If you are a sole proprietor, the contribution limits are confusing in your situation because your total earned income will be over the social security wage base for 2017 ($127,200).  However, the general rule is that the maximum contribution for a sole proprietor is 20% of net profit reduced by half self-employment tax (The 25% limit applies to employees, and many people mistakenly use that, instead of 20%). If you were under the wage base, the maximum contribution you can make is approximately 18.59% of your net profit. It may be slightly more than that in your case.

See IRS Publication 590 for worksheets to calculate your maximum SEP-IRA contribution.

How much can I contribute to my SEP?

The contributions you make to each employee’s SEP-IRA each year cannot exceed the lesser of:

1. 25% of compensation, or
2. $54,000 for 2017 ($53,000 for 2015 and 2016 and subject to annual cost-of-living adjustments for later years).

These limits apply to contributions you make for your employees to all defined contribution plans, which includes SEPs. Compensation up to $270,000 in 2017 ($265,000 in 2015 and 2016 and subject to cost-of-living adjustments for later years) of an employee’s compensation may be considered. If you're self-employed, use a special calculation to determine contributions for yourself.

Contributions must be made in cash; you cannot contribute property.

If you’ve contributed more than the annual limits to your SEP plan, find out how to correct this mistake.
