Who Contributes to SEP-IRA Accounts?
Only the employer makes contributions to SEP-IRA accounts.
Nothing is withheld from an employee's pay (unless the SEP plan is a Salary Reduction Simplified Employee Pension (SARSEP) started before 1997).
After 1996, SARSEPs could no longer be established. However, if an employer has been operating one since before 1997, the plan may continue to operate and even allow new employees to participate in it.
Contributions must be in the form of money (cash, check, or money order). However, participants may be able to transfer or roll over certain property from one retirement plan to another. See IRS publication 590 for rollover and other IRA information.

You can set up a SEP-IRA and make contributions for a particular year as late as the due date of your income tax return, plus extensions.

(Due to COVID-19 the filing date for Form 1040 and automatic extensions was extended to July 15, 2020.)
