If you’re a federal employee, your retirement is built on one of the most powerful systems available—FERS, TSP, and your pension. But here’s the problem: even with strong benefits, small mistakes can cost you thousands over time. Many federal employees assume that simply “being in the system” is enough. In reality, how you manage it determines your outcome.
The biggest risks don’t come from market crashes—they come from avoidable planning errors. Whether it’s misunderstanding withdrawal rules, misaligning your pension, or overlooking tax strategies, these mistakes can quietly reduce your retirement income.

A detailed review ensures that your pension aligns with your retirement goals and avoids unexpected shortfalls.
2. Poor TSP Allocation and Lack of Strategy
Why “Set It and Forget It” Can Cost You
