Tax Optimization for a W-2 Employee

The 7 levers most people leave on the table every year.

Who it's for

You're a salaried employee in the US who takes the standard deduction.

What you'll have at the end

A checklist of pre-tax and tax-advantaged moves that can save $2,000–$10,000+ per year.

You probably can't itemize your way to lower taxes. But there are 7 structural moves that reduce your taxable income before deductions even matter.

Match capture
100%
Tax-advantaged $/yr maxed
$30k–$50k+
Long-term capital gain rate
0–20%
  1. 01

    Max the 401(k) match — minimum

    An employer match is a guaranteed 50–100% return. If your match is 'up to 6%', contributing less than 6% is leaving direct cash on the table.

  2. 02

    Use the HSA if you're eligible

    If your health plan is HSA-eligible, the HSA is the most tax-advantaged account in the US: pre-tax in, tax-free growth, tax-free out for medical. Invest it, don't spend it.

  3. 03

    Fund a Roth IRA (or backdoor Roth)

    $7,000/year of tax-free growth forever. Above the income limit? Use the backdoor Roth (contribute to a traditional IRA, immediately convert).

    PitfallBackdoor Roth pro-rata trap if you have other pre-tax IRA money. Roll it into your 401(k) first.
  4. 04

    Use commuter / dependent-care benefits

    Pre-tax dollars for transit, parking, or daycare. Easy 22–32% discount on expenses you'd have anyway.

  5. 05

    Harvest tax losses in taxable accounts

    Sell losing positions to offset gains plus up to $3,000 of ordinary income per year. Carry the rest forward.

  6. 06

    Hold long, sell long

    Hold for 12+ months to convert short-term gains (taxed as income) into long-term gains (taxed at 0/15/20%).

    Capital gains tax
  7. 07

    Bunch deductions if you're near the threshold

    If your itemized deductions are close to the standard deduction, stack 2 years of charitable giving into one tax year (donor-advised fund), then take the standard deduction next year.
