Hi and welcome to Just Answer!Theer is no difference for Roth IRA contribution - if you have C-corp or S-corp.
Contributions into Roth IRA are not based on type of the corporation but rather on other conditions.his table shows whether your contribution to a Roth IRA is affected by the amount of your modified AGI as computed for Roth IRA purpose. See here - http://www.irs.gov/Retirement-Plans/Plan-Participant,-Employee/Amount-of-Roth-IRA-Contributions-That-You-Can-Make-for-2012
For 2012, the maximum you can contribute to all of your traditional and Roth IRAs is the smaller of:---$5,000 ($6,000 if you’re age 50 or older), or--your taxable compensation for the year.For 2013, the maximum you can contribute to all of your traditional and Roth IRAs is the smaller of:--$5,500 ($6,500 if you’re age 50 or older), or--your taxable compensation for the year.
I heard it was 16,000 for a C-Corp, but need more information.
That is possible - but with different retirement plan - not with Roth IRA,
However - you may have different retirement plan with either C-corp or S-corp - no difference.
I guess I need to find out where they got their information from. I'.m having a lot of trouble trying to find answers about corporations. Met with 4 different accountants and received 4 different answers on questions.
For instance - you may have 401k plan and have larger contributions - see here for limits - http://taxes.about.com/od/retirementtaxes/qt/401k-contribution-limits.htm
