I put this together as a convenient reference to the maximum contribution limits for various retirement programs.
You can find useful information at the IRS's website here and here.
Here's a summary of the most useful information:
These are the maxium contributions for various retirements accounts in tax year 2007.
401k, 403b and SARSEP (these are defined contribution programs):
$15,500 for salary deferal (pre-tax money from your paycheck)
Catch-up contributions of up to $5k can be made.
The total contribution (inluding company match and profit share) is $45,000.
The maximum annual benefit for a pension plan (defined benefit) is $180,000.
SEP IRA (more details)
The maximum total contribution to a SEP is limited to the lesser of 25% of income or $45,000.
(small business owners with SEPs can issue matches and profit shares to their sep - but cannot exceed the aforementioned limits.)
$10,500 salary deferal with a $2,500 catch-up
(over 50) $5,000
Social Security Taxable Income Limit (6.2% paid by both employee and employer)
(this is per job)
Have a great weekend,
