When determining how much can be contributed to your IRA, it may be helpful to know which income is not considered "compensation."

Per IRS IRS Publication 590-A Contributions to Individual Retirement Arrangements (IRAs), page 6:

What Isn't Compensation?

Compensation doesn't include any of the following items:

• Earnings and profits from property, such as rental income, interest income, and dividend income.
• Pension or annuity income.
• Deferred compensation received (compensation payments postponed from a past year).
• Income from a partnership for which you don't provide services that are a material income-producing factor.
• Conservation Reserve Program (CRP) payments reported on Schedule SE (Form 1040), line 1b.
• Any amounts (other than combat pay) you exclude from income, such as foreign earned income and housing costs.
