How To Invest in the L Funds
Step 1  
Determine your time horizon.
Your time horizon is defined as the date you will need the money that is in your TSP account after leaving Federal service. Your time horizon may be later than your retirement date.
Step 2
Identify the L Fund that matches your time horizon.
  If your time horizon is:
L 2040
  2035 or later
L 2030
  2025 through 2034
L 2020
  2015 through 2024
L 2010
  2008 through 2014
L Income
  Sooner than 2008 or if you are already withdrawing your account in monthly payments.
Step 3
Make two transactions to invest in the L Fund.
  • Use your Social Security number and your TSP Personal Identification Number (PIN) to make these transactions in the Account Access section of this Web site. You can also use the Thriftline or ask your agency or service for an Investment Allocation Form (TSP-50, or, if you are a member of the uniformed services, TSP-U-50).
  • A contribution allocation directs how new money coming into your account (payroll contributions, transfers into the TSP, loan payments) will be invested. It does not affect your existing account balance.
  • An interfund transfer moves your existing account balance into the funds you choose. It is a one-time transaction that affects your existing balance. It has no effect on new money coming into your account.
You can invest any portion of your account in the L Funds, and you can invest in more than one of the Funds (as well as in the individual TSP funds). However, think carefully before investing in multiple funds. The L Funds are designed so that 100% of your TSP account should be invested in the single L Fund that most closely matches your time horizon. Any other use of the L Funds may result in less than optimal returns, a higher amount of risk in your portfolio, or both.
