The IRS recently announced increased contribution limits for various qualified retirement plans for tax year 2013. The limitations are indexed to increases in cost-of-living (inflation) as per section 415 of the tax code. In particular, the elective deferral (contribution) limit for employees who participate in 401(k), 403(b), most 457 plans, and the federal government’s Thrift Savings Plan is increased from $17,000 to $17,500. However, the additional catch-up contribution allowed for those age 50 and higher remains $5,500.
The limits are the same for both Roth and “Traditional” pre-tax 401k plans, although the effective after-tax amounts can be quite different. Employer match contributions do not count towards the $17,000 elective deferral limit. (Although technically the total annual defined contribution limit is $51,000 for 2013… let me know if you have an employer that is so generous!) Curiously, some employer plans set their own limit on contributions. A former employer of mine had a 20% deferral limit, so if your income was $50,000 the most you could put away was $10,000 a year.
Here’s a historical chart and table of recent contribution limit increases:
