High W-2 earners are the most heavily marketed audience for tax strategies, and also the group with the fewest levers. Wages are "non-passive" income, and the tax code walls off many deductions and credits from them. This guide sorts the common ideas into what generally can reduce tax on wages, and what generally cannot, with the rule behind each.

What can reduce tax on wages

1. Pre-tax retirement contributions

For 2026 the employee deferral limit for 401(k), 403(b), governmental 457 plans and the Thrift Savings Plan is $24,500. The age 50+ catch-up is $8,000, and employees aged 60 to 63 have a higher catch-up of $11,250. The IRA contribution limit is $7,500.¹ Traditional (pre-tax) deferrals reduce taxable wages now; Roth deferrals do not, but grow tax-free. See Roth conversions for the trade-off.

2. Health savings accounts

If you have a qualifying high-deductible health plan, the 2026 HSA deduction limit is $4,400 for self-only coverage and $8,750 for family coverage.²

3. A cash balance plan, if you also have self-employment or business income

A defined benefit (cash balance) plan can allow much larger deductible contributions than a 401(k) for business owners and some professionals with self-employment income. It does not apply to W-2 wages from someone else's company. See cash balance plans.

4. Charitable giving, timed well

Deductions for gifts only help if you itemize. Some people "bunch" several years of giving into one year through a donor-advised fund. The 2025 law changed charitable deduction rules starting in 2026; check the IRS page before planning a large gift.³

What usually cannot reduce tax on wages

Passive losses and passive credits

Losses and credits from businesses you do not materially participate in, and from most rentals, are passive. They generally offset only passive income, not wages; the excess carries forward.⁴ This covers most solar equipment investments, most real estate syndications, and purchased tax credits for individuals.⁵ See can solar credits offset W-2 income?.

Rental real estate losses, with two exceptions

Rental real estate losses are generally passive. Two exceptions exist:⁴

Active participation allowance: up to $25,000 of rental real estate losses for active participants, phased out as modified adjusted gross income rises from $100,000 to $150,000.
Real estate professional status: more than half of your personal services, and more than 750 hours, in real property businesses in which you materially participate. Full-time W-2 employees outside real estate rarely qualify.

Short-term rentals with average stays of seven days or less are analyzed differently; see short-term rental losses.

Very large business losses

Even non-passive business losses above an annual threshold are disallowed for the year and carried forward (the excess business loss limit, §461(l)).⁶

How to use this

Max out the plain-vanilla options first; they have the lowest IRS scrutiny.
For anything that promises to offset wages with a credit or loss, ask exactly which rule lets it be non-passive.

Common questions

What is the most common way to reduce taxes on W-2 income?

Pre-tax retirement contributions. For 2026 the 401(k) employee deferral limit is $24,500, with an $8,000 catch-up at age 50 and over and an $11,250 catch-up for ages 60 to 63.

Can real estate losses offset W-2 income?

Generally not, because rental losses are passive. Exceptions are the $25,000 active participation allowance (phased out between $100,000 and $150,000 of modified AGI) and real estate professional status, which requires more than 750 hours and more than half of your working time in real property businesses.

Can solar tax credits offset W-2 income?

Generally not for passive investors or for individuals who buy credits; those credits are passive and generally offset only tax on passive income.
