taxmap/pubs/p560-016.htm#en_us_publink10008977You can usually deduct, subject to limits, contributions you make to a qualified plan, including those made for your own retirement. The contributions (and earnings and gains on them) are generally tax free until distributed by the
plan.
taxmap/pubs/p560-016.htm#en_us_publink10008978The deduction limit for your contributions to a qualified plan depends on the kind of plan you
have.
taxmap/pubs/p560-016.htm#en_us_publink10008979The deduction for contributions to a defined contribution plan (profit-sharing plan or money purchase pension plan) cannot be more than 25% of the compensation paid (or accrued) during the year to your eligible employees participating in the plan. If you are self-employed, you must reduce this limit in figuring the deduction for contributions you make for your own account. See
Deduction Limit for Self-Employed Individuals,
later.
When figuring the deduction limit, the following rules apply.
- Elective deferrals (discussed later) are not subject to the
limit.
- Compensation includes elective deferrals.
- The maximum compensation that can be taken into account for each employee in 2011 is $245,000 ($250,000 for
2012).
taxmap/pubs/p560-016.htm#en_us_publink10008980The deduction for contributions to a defined benefit plan is based on actuarial assumptions and computations. Consequently, an actuary must figure your deduction
limit.
 | In figuring the deduction for contributions, you cannot take into account any contributions or benefits that are more than the limits discussed earlier under Limits on Contributions and Benefits. However, your deduction for contributions to a defined benefit plan can be as much as the plan's unfunded current
liability. |
taxmap/pubs/p560-016.htm#en_us_publink10008982If you make contributions for yourself, you need to make a special computation to figure your maximum deduction for these contributions. Compensation is your net earnings from self-employment, defined in chapter 1. This definition takes into account both the following items.
- The deduction for the deductible part of your self-employment
tax.
- The deduction for contributions on your behalf to the plan.
The deduction for your own contributions and your net earnings depend on each other. For this reason, you determine the deduction for your own contributions indirectly by reducing the contribution rate called for in your plan. To do this, use either the
Rate Table for Self-Employed
or the
Rate Worksheet for Self-Employed
in chapter 5. Then figure your maximum deduction by using the
Deduction Worksheet for Self-Employed
in chapter 5.
taxmap/pubs/p560-016.htm#en_us_publink10008983Deduct the contributions you make for your common-law employees on your tax return. For example, sole proprietors deduct them on Schedule C (Form 1040), Profit or Loss From Business, or Schedule F (Form 1040), Profit or Loss From Farming; partnerships deduct them on Form 1065, U.S. Return of Partnership Income; and corporations deduct them on Form 1120, U.S. Corporation Income Tax Return, or Form 1120S, U.S. Income Tax Return for an S
Corporation.
Sole proprietors and partners deduct contributions for themselves on line 28 of Form 1040, U.S. Individual Income Tax Return. (If you are a partner, contributions for yourself are shown on the Schedule K-1 (Form 1065), Partner's Share of Income, Deduction, Credits, etc., you get from the
partnership.)
taxmap/pubs/p560-016.htm#en_us_publink10008984If you contribute more to the plans than you can deduct for the year, you can carry over and deduct the difference in later years, combined with your contributions for those years. Your combined deduction in a later year is limited to 25% of the participating employees' compensation for that year. For purposes of this limit, a SEP is treated as a profit-sharing (defined contribution) plan. However, this percentage limit must be reduced to figure your maximum deduction for contributions you make for yourself. See
Deduction Limit for Self-Employed Individuals,
earlier. The amount you carry over and deduct may be subject to the excise tax discussed
next.
Table 4-1
on the previous page illustrates the carryover of excess contributions to a profit-sharing plan.

taxmap/pubs/p560-016.htm#en_us_publink10008985If you contribute more than your deduction limit to a retirement plan, you have made nondeductible contributions and you may be liable for an excise tax. In general, a 10% excise tax applies to nondeductible contributions made to qualified pension and profit-sharing plans and to
SEPs.
taxmap/pubs/p560-016.htm#en_us_publink10008986The 10% excise tax does not apply to any contribution made to meet the minimum funding requirements in a money purchase pension plan or a defined benefit plan. Even if that contribution is more than your earned income from the trade or business for which the plan is set up, the difference is not subject to this excise tax. See
Minimum Funding Requirement,
earlier.
taxmap/pubs/p560-016.htm#en_us_publink10008987You must report the tax on your nondeductible contributions on Form 5330. Form 5330 includes a computation of the tax. See the separate instructions for completing the
form.
