Enter your deduction for contributions to a pension, profit-sharing, or annuity plan, or plan for the benefit of your employees. If the plan included you as a self-employed person, enter contributions made as an employer on your behalf on Form 1040, line 28, or Form 1040NR, line 28, not on Schedule C.
In most cases, you must file the applicable form listed below if you maintain a pension, profit-sharing, or other funded-deferred compensation plan. The filing requirement is not affected by whether or not the plan qualified under the Internal Revenue Code, or whether or not you claim a deduction for the current tax year. There is a penalty for failure to timely file these forms.
