W-2 Only: Employer Benefits Maximization

Without side income, your tax planning focuses on employer benefits, retirement plans, and investment strategies. This guide covers these W-2-specific levers.

Your optimization levers are different. Without self-employment income, entity structuring and Solo 401(k) plans are off the table. Instead, a CPA focuses on maximizing what is available: employer retirement plans, investment tax efficiency, charitable strategies, and timing of income recognition.

Retirement contributions are your biggest deduction. Max out your 401(k) or 403(b) at the employee limit ($23,500 for 2025, plus $7,500 catch-up if you are 50 or older). If your employer offers after-tax contributions with in-plan Roth conversion (mega backdoor Roth), that can shelter an additional $46,500 per year from future taxation.

Investment tax efficiency matters at high brackets. Tax-loss harvesting in taxable accounts, holding appreciating assets long-term for the lower capital gains rate, and placing tax-inefficient assets (bonds, REITs) inside tax-advantaged accounts all reduce what you owe. A CPA coordinates this with your overall tax picture.

Charitable strategies amplify deductions. Donating appreciated stock avoids capital gains entirely. Bunching multiple years of giving into a donor-advised fund in a single year can push you above the standard deduction threshold.

The tradeoff: Without a business, you have fewer levers to pull. Every available strategy must be executed precisely to make a meaningful dent at high income levels.
