In Retirement Plan News For Employers, February 24, 2014, the IRS says the following on setting up a SEP Retirement Plan.
If you own a business, you still have time to set up a Simplified Employee Pension (SEP) plan for 2013. If you set up and fund your SEP by the due date of your 2013 business return (including extensions), you can still take a deduction for 2013. If your business uses the calendar year for its tax year, the deadline to set up and contribute to a SEP plan for 2013 depends on the type of your business organization:
• If your business is a corporation, filing Form 1120 or 1120S, you have until March 15, 2014 (September 15, 2014, if you file for an extension).
• If your business is a partnership, filing Form 1065, you have until April 15, 2014 (September 15, 2014, if you file for an extension).
• If your business is a sole proprietorship, reported on Schedule C of Form 1040,
you have until April 15, 2014 (October 15, 2014, if you file for an extension).
You can set up a SEP plan for little or no cost at a bank, investment firm or insurance company.
SEP plans offer high contribution and deduction limits, minimal paperwork and no annual Form 5500 filing. You can contribute to a SEP plan even if you participate in an unrelated employer’s plan (for example, a 401(k) plan). Contributions to a SEP plan are subject to the SEP contribution limits. Other kinds of business-sponsored retirement plans must have been established before the end of 2013 in order for the business to get a deduction for 2013.
