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.
Contributions can be made to a SEP-IRA after age 70 1/2, and distributions are subject to the same rules that govern traditional deductible IRA distributions. It may seem strange, but if you continue to work after age 70 1/2, youâll have to take taxable withdrawals in the same year you make deductible contributions.f Roger establishes an individual 401(k) plan instead of a SEP-IRA, he could contribute up to $34,440 for 2008. In addition, he could contri-bute $6,000 to his own Roth IRA and $6,000 to a deductible IRA in Katieâs name. In this case, retirement savings can be as high as $46,440 â nearly 62 percent of Rogerâs income.
