- Employee contribution limit increased to $23,500 (up from $22,500 last year).

🔁 Why You Should Revisit Your Contribution Strategy
Changing your 401k contribution isn’t just about increasing your savings. It’s also about making strategic moves based on your income level, age, retirement horizon, and tax preferences. Here’s why:
- To maximize the 2025 limit before the year ends.
- To enable catch-up contributions if you’re 50 or older.
- To switch between traditional and Roth contributions.
- To align savings with recent salary hikes or bonuses.
📋 Step-by-Step: How to Change My 401k Contribution in 2025
Changing your contribution is usually straightforward but varies slightly based on your employer’s benefits provider.
✅ Step 1: Log Into Your Retirement Portal
Most employers use platforms like Fidelity, Vanguard, Empower, or ADP. You’ll need to log into your retirement dashboard or benefits portal.
✅ Step 2: Navigate to “Contribution Settings”
Once logged in, locate the section labeled something like:
- “Contribution Rate”
- “Salary Deferral”
- “Change My 401(k) Contributions”
Click into it to view your current rate.
✅ Step 3: Choose Your New Contribution Rate
You can enter a:
- Percentage of your salary (e.g., 10%)
- Flat dollar amount per pay period
Make sure you don’t exceed the $23,500 annual limit (or up to $34,750 if eligible for super catch-ups).
✅ Step 4: Decide Between Pre-Tax and Roth
Many plans allow you to split contributions:
- Traditional 401k: Contributions are tax-deferred.
- Roth 401k: Contributions are taxed now but withdrawn tax-free in retirement.
Pro tip: High earners over 50 must make catch-up contributions as Roth if their income crosses a certain threshold.
✅ Step 5: Save Changes and Confirm
Always double-check:
- Paycheck deduction start date
- Confirmation email or portal notice
- Whether automatic escalations are enabled
