To establish a Guideline SEP you need to complete IRS Form 5305-SEP. In addition, if you have eligible employees, you must add them to your SEP and provide them with a copy of your completed Form 5305. You are required to notify your eligible employees about any SEP contributions that you make to their SEP IRAs annually. Guideline provides this to employees on your behalf annually by distributing a Form 5498 to participants who establish Guideline SEP IRAs. Other than your regular tax filings, there are no additional annual reporting or filing requirements.
