TSP.gov Portal Walkthrough: Access, Contributions, Funds, Loans, and Beneficiaries
The TSP portal is where federal and military retirement savings become visible: balances, funds, statements, beneficiaries, loans, withdrawals, and account security. For service members, the catch is that contribution changes often start in payroll systems like myPay, while investment allocation and account management live at TSP.gov.
Educational information, not financial advice. TSP rules, contribution limits, tax treatment, and withdrawal choices can change; verify decisions against official TSP and IRS guidance. Last verified: July 7, 2026.
How to handle TSP.gov
Separate contribution changes from investment choices
For many service members, changing how much of your pay goes to TSP starts in myPay or service payroll. TSP.gov is where you manage the TSP account itself, investment elections, beneficiaries, statements, and withdrawals.
Set up secure access and recovery
Use strong MFA, confirm phone/email recovery, and keep contact information current. Retirement accounts are high-value fraud targets.
Review current and future allocations
Current allocation is where existing money is invested. Future contribution allocation is where new money goes. If you only change one, your account may not behave the way you expect.
Check beneficiaries after life events
Marriage, divorce, birth, death, and remarriage should trigger a TSP beneficiary review. Do not assume a will automatically controls every retirement-account outcome.
Treat loans and withdrawals as last-resort tools
The portal exposes loan and withdrawal options, but availability does not mean good idea. Understand repayment, taxes, penalties, and lost market exposure before taking money out.
Understand Roth conversion before clicking
TSP announced Roth in-plan conversions as available in 2026. Converting traditional money to Roth can create taxable income now. Model the tax hit before acting.
The problems people actually search for
I changed my TSP fund but my paycheck contribution did not change.
Usually means: You changed investment allocation at TSP.gov, not the payroll contribution percentage in myPay or your service payroll system.
Move: Use payroll/myPay for contribution percentage and Roth/traditional election. Use TSP.gov for investing the money once it reaches the account.
My current balance and future contributions are invested differently.
Usually means: TSP separates current allocation from future contribution allocation. Changing one does not always rebalance the other.
Move: Review both current investment mix and future contribution allocation after every change. Document the confirmation screen.
I cannot log in after the account/security transition.
Usually means: Identity proofing, MFA, old contact data, or account recovery information is stale.
Move: Use TSP access/account recovery support, update contact methods once in, and do not wait until withdrawal/loan deadline to test access.
A loan or withdrawal looks easy in the portal.
Usually means: The portal can show availability without explaining whether the tax, repayment, or separation consequences are good for you.
Move: Before submitting, calculate taxes, penalties, repayment impact, spouse consent if applicable, and what happens if you separate before repayment is complete.
Beneficiary info is old or not what I expected.
Usually means: Beneficiary designations can lag life events and may not match wills, divorce decrees, or assumptions.
Move: Update beneficiaries directly in TSP after marriage, divorce, birth, death, or remarriage. Save confirmation.
Roth conversion sounds like free tax savings.
Usually means: Roth conversion can be useful, but converting traditional balance creates taxable income now.
Move: Model the tax year impact before clicking. Consider rank/pay, spouse income, deployment tax status, state tax, credits, and whether conversion pushes you into a worse bracket.
Where people usually get stuck
You adjusted investment allocation but your paycheck contribution stayed the same.
Existing money and new money are invested differently by accident.
Old spouse, parent, or no beneficiary remains on file after a life change.
Roth conversion creates a bigger tax bill than expected.
Build the proof packet before you escalate
- Screenshot of current allocation and future contribution allocation after any change.
- LES showing TSP traditional/Roth contribution actually deducted from pay.
- TSP transaction confirmation number and date.
- Beneficiary confirmation after life events.
- Loan or withdrawal estimate showing amount, repayment/tax details, and requested date.
- For Roth conversion: estimated converted amount, taxable income estimate, federal/state bracket, and whether combat-zone tax rules apply.

Fast answers
Do I change TSP contributions on TSP.gov?
Service members often change paycheck contribution elections through myPay or their payroll system, not directly at TSP.gov. TSP.gov manages the retirement account and investment side.
What is the difference between C/S/I/F/G and L Funds?
C, S, I, F, and G are individual fund options. L Funds are lifecycle funds that hold a mix of funds and adjust over time for a target retirement period.
Are Roth in-plan conversions available?
TSP.gov stated that Roth in-plan conversions became available in My Account as of January 28, 2026. Check current TSP rules and tax impact before using it.
Should I take a TSP loan?
Usually only after comparing alternatives. Loans reduce invested balance, create repayment obligations, and can become taxable if mishandled after separation.
