1 For contributions made on behalf of common-law employees, the partnership claims the deduction on IRS Form 1065. 2  For an S-corporation, all SEP contributions are claimed on IRS Form 1120S. 3  For a C-corporation, all SEP contributions are claimed on IRS Form 1120-A.
For self-employed people with no employees, first, compare a SEP to an Individual 401(k) plan to decide which plan is best for you. The Individual 401(k) may allow you to switch between Roth 401(k) (after-tax) and Regular 401(k) (pre-tax) contributions based on your tax bracket.
