The IRS recently announced the contribution limits for retirement savings programs in 2018.

For the Thrift Savings Plan, the annual contribution limit is increasing from $18,000 to $18,500 per year. The catch-up contribution limit for employees aged 50 and over will remain unchanged at $6,000 per year. These figures only apply to the individual contribution amounts and do not include any agency matches. For details on how you can incorporate these changes into your TSP savings plan, see Retirement Success Habit: Getting Your TSP Ready For 2018.

For IRAs, the annual contribution limit will remain unchanged at $5,500 per year. This applies to the Roth IRA as well.
