Chloroplast: Photosynthesis. In photosynthesis, the sun's solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar). Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water.
SEP IRA Contribution Limits 2013. You can contribute up to 25% of your total salary or 20% of your adjusted annual income to a SEP IRA, up to a limit of $51,000 in tax year 2013. This is almost twice the limit for 401(k) investors.
Because a SEP-IRA is a traditional IRA, you may be able to make regular, annual IRA contributions to this IRA, rather than opening a separate IRA account. However, any dollars you contribute to the SEP-IRA will reduce the amount you can contribute to other IRAs, including Roth IRAs, for the year.
