Annual funding amounts are determined based on a variety of criteria including age, compensation (or business income) and investment returns. If you are looking to make higher contributions, you should consider the following: Increase your wage. If you do not have employees, then typically you can get your W2 up to $230,000. That is generally the highest applicable compensation. If you have employees, then you should consider increasing your W2 up to $290,000. Consider adding a spouse. If your spouse works for your business then you should consider including them on payroll and/or increasing their compensation. This can also allow them to get a defined benefit plan contribution and possibly make a 401k contribution as well. Review your investment mix. Remember that these plans use an implied interest rate of 5%. If your assets earn more than this, it will tend to push your contributions lower. Make sure that aggressive and volatile investments are held in your 401k plans and IRAs. Consider certain insurance products. While these are not always the best investments, they can reduce plan assets and allow for larger contributions. Remember that these plans are just one part of your tax and retirement strategy. Make sure you review the items noted above with your CPA and financial advisor.
