Tax strategies for W-2 employees: how to cut taxes on a salary in 2026
A W-2 earner making $300K can cut taxes without a business. Fill pre-tax accounts first: the 401(k) up to $24,500 and an HSA up to $8,750 for a family. Then use after-tax 401(k) room for a mega backdoor Roth, the higher SALT cap, and charitable bunching. A short-term rental is the large move if you will run one.
A paycheck is the hardest income to shelter. There is no entity to route it through, and unreimbursed employee expenses are not deductible on a federal return. So the moves below are grouped by what each one asks of you.
Education, not tax advice
This page explains how the rules work. It is not advice for your situation. Every number on it is an example with its assumptions written out. Check your own facts with a CPA or enrolled agent before you file.
How much can a $300K W-2 earner save without a business?
Here are two examples, not forecasts. Both use 2026 brackets and limits from Rev. Proc. 2025-32 and IRS Notice 2025-67, and federal income tax only.
| Example | Single, $300,000 salary | Married, one $300,000 salary |
|---|---|---|
| Standard deduction | $16,100 | $32,200 |
| Taxable income before any moves | $283,900 | $267,800 |
| Top bracket before any moves | 35% (starts at $256,225) | 24% (starts at $211,400) |
| Pre-tax 401(k) | $24,500 | $24,500 |
| HSA through payroll | $4,400 (self-only) | $8,750 (family) |
| Taxable income after | $255,000 | $234,550 |
| Federal income tax saved | $10,078 ($27,675 at 35% plus $1,225 at 32%) | $7,980 ($33,250 at 24%) |
The same salary is taxed very differently by filing status. A single earner at $300,000 is already in the 35% bracket. A married couple on one $300,000 salary is in the 24% bracket. That changes which moves are worth the work.
After these two accounts, a mega backdoor Roth does not cut this year's tax, but it moves up to the $72,000 total 401(k) limit into tax-free growth if your plan allows after-tax contributions and in-plan conversions. A backdoor Roth IRA adds $7,500 a person. Check your own numbers with the marginal vs effective tax rate calculator.
What changes in the 37% bracket for a salaried executive?
In 2026 the 37% bracket starts at $640,600 of taxable income for a single filer and $768,700 for a married couple. A salaried executive there also pays the 0.9% Additional Medicare Tax on wages above $200,000 single or $250,000 married, plus any state tax.
- Pre-tax deferrals are worth the most here. Each $10,000 into a 401(k), HSA, or a company deferred compensation plan saves $3,700 of federal income tax. Deferred comp carries the risk of your employer's credit, so read the plan.
- The SALT cap shrinks. The 2026 cap is $40,400, but it drops by 30 cents per dollar of income above $505,000 and bottoms out at $10,000 once income reaches about $606,333. Most 37% earners get the $10,000 floor.
- Itemized deductions are worth less. Starting in 2026, the law limits the tax value of itemized deductions for people in the 37% bracket to about 35 cents per dollar, and charitable gifts only count above 0.5% of income.
- Equity pay is under-withheld. Bonuses and RSUs are usually withheld at 22% up to $1 million. At a 37% rate the gap shows up in April. Fix it with Form W-4 line 4(c) or estimated payments.
- Large deductions need an activity. At this income the moves that change the bill by five figures are a rental you can count as non-passive, through the short-term rental loophole or a spouse with real estate professional status, or a donor-advised fund funded with appreciated stock in a high-income year.
What does our own data show?
Preston spent four and a half years as a W-2 employee in software sales, from June 2017 to December 2021, and bought his first rental, a 4-plex, in September 2018 while he held that job. The moves on this page are the ones open to someone in that seat.
Of the 61 wealth plans we published between August 2025 and April 2026, 36 mention W-2 income. In a May 2026 video, Preston says that in reviewing 100 returns of W-2 earners over $300,000, 94 had missed savings, with an average miss just over $42,000 a year. The most common pattern was stopping at the 401(k) match. Plans are planning scenarios, not results, and names are left out.
What does Preston say about W-2 taxes on video?
I Audited 100 W-2 Returns Earning $300K+. Here's What 94 of Them Got Wrong. (8 min, May 2026). Preston describes four patterns from reviewing returns of W-2 earners over $300K: stopping at the 401(k) match, side income with no structure, no planning meeting with the CPA, and missed 2025 law changes such as the higher SALT cap and permanent 100% bonus depreciation.

7 Tax Strategies for W2 $100K-$1M Earners (CPAs never mention) (23 min, November 2025). Preston covers seven moves for high-earning W-2 households: the short-term rental loophole, real estate professional status through a spouse, retirement plans past the basic 401(k), the Augusta rule for owners with a business, oil and gas working interests, private foundations, and bitcoin mining equipment. Watch on YouTube.
The second video was made in November 2025 and quotes 2025 limits. For 2026 the 401(k) limit is $24,500, the total 401(k) limit is $72,000, and the IRA limit is $7,500.
Which moves work on a W-2 salary?
Grouped by what each one asks of you, not by the size of the deduction. Start at the top of the first group. Most of these have a December 31 deadline, so the calendar matters as much as the math.
Which moves need no business?
These work with nothing but your own payroll elections and a brokerage account. Start here, because they are the only moves fully under your control.
1. Health savings account
A Health Savings Account (HSA) offers a triple tax advantage: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Many investors use HSAs as stealth retirement accounts by paying current medical expenses out-of-pocket and letting the HSA grow.
| Potential savings | Triple tax benefit with annual contribution limits |
| Best fit | Healthy individuals with high-deductible health plans |
| Level | beginner |
| Typical cost | Free with most providers |
2. Mega backdoor Roth
Uses after-tax 401(k) contributions and in-plan conversion to add Roth dollars above the deferral limit.
| Level | advanced |
3. Backdoor Roth IRA
Reaches a Roth IRA through a non-deductible contribution and conversion when income exceeds the Roth limits.
| Level | intermediate |
4. Dependent care FSA
Pays childcare and dependent care costs with pre-tax payroll dollars.
| Level | beginner |
5. Tax loss harvesting
Sells losing positions to offset realized gains while respecting the wash-sale rule.
| Level | beginner |
6. Bunching deductions
Concentrates two years of charitable gifts and other itemized deductions into one year to clear the standard deduction.
| Level | beginner |
7. Donor-advised fund
Takes the charitable deduction in the year the account is funded and grants the money out later.
| Level | intermediate |
Which moves need a rental?
These only exist if you own property. They can be the largest numbers on the page, and they carry the most work, the most records, and depreciation recapture when you sell.
8. Short-term rental loophole
A rental whose average period of customer use is seven days or less is not a rental activity under Reg. 1.469-1T(e)(3)(ii)(A). It is treated as a trade or business, so its loss is not passive when you materially participate. That lets the loss offset W-2 income in the same year, without meeting the 750-hour and more-than-half tests for real estate professional status.
| Potential savings | A large first-year loss against W-2 income when both tests are met |
| Best fit | W-2 earners who run the bookings themselves in a short-stay market |
| Level | intermediate |
| Typical cost | Often $5,000 - $15,000 for the cost segregation study, plus tax preparation |
9. Cost segregation
Cost segregation is a tax strategy that allows real estate investors to accelerate depreciation deductions by reclassifying components of a building into shorter depreciation periods. Instead of depreciating the entire property over 27.5 or 39 years, certain components like carpeting, appliances, and landscaping can be depreciated over 5, 7, or 15 years.
| Potential savings | $20,000 - $100,000+ in year one |
| Best fit | Properties worth $500K+ purchased or renovated recently |
| Level | advanced |
| Typical cost | $5,000 - $15,000 for a study |
10. Bonus depreciation
Bonus depreciation lets you deduct qualifying property in the year it is placed in service instead of spreading it over the recovery period. For 2026 the rate is 100 percent for qualified property acquired after January 19, 2025, made permanent by the 2025 tax law in Section 168(k). Property under a binding contract on or before January 19, 2025 stays on the old phase-down and gets 20 percent in 2026.
| Potential savings | 100% of qualifying asset cost as a first-year deduction |
| Best fit | Equipment, vehicles, and the short-life components a cost segregation study finds |
| Level | intermediate |
| Typical cost | Included in standard tax preparation |
Which moves need a spouse or a side business?
These need income or hours that a full-time job leaves no room for. On a joint return a spouse can meet tests you cannot.
11. Real estate professional status
Real Estate Professional Status is an IRS designation that allows qualifying taxpayers to deduct rental real estate losses against their ordinary income without passive activity loss limitations. This can result in significant tax savings for high-income earners who materially participate in their real estate activities.
| Potential savings | Rental losses against W-2 income, up to the 2026 excess business loss cap of $512,000 joint |
| Best fit | Those who spend 750+ hours annually in real estate activities |
| Level | advanced |
| Typical cost | Included in tax preparation, but requires detailed time tracking |
12. Solo 401(k)
A Solo 401(k), also known as an Individual 401(k), is a retirement plan for self-employed individuals with no full-time employees. It allows significantly higher contribution limits than a traditional IRA, plus the ability to take loans from your account and invest in alternative assets.
| Potential savings | High annual contribution ceiling with catch-up options |
| Best fit | Self-employed individuals with high income |
| Level | intermediate |
| Typical cost | $0 - $300/year depending on provider |
13. S-corp election
An S-Corporation election allows business owners to split their income between a reasonable salary (subject to payroll taxes) and distributions (not subject to self-employment tax). This can result in significant savings on the 15.3% self-employment tax.
| Potential savings | 10-15% of business income |
| Best fit | Self-employed individuals earning $50K+ in profit |
| Level | intermediate |
| Typical cost | $500 - $2,000/year for payroll and additional tax prep |
14. Qualified business income deduction
Deducts up to 20% of qualified pass-through business income.
| Level | intermediate |
What should you check before December 31?
- Your 401(k) election will reach $24,500 by your last paycheck ($32,500 if you are 50 or older, $35,750 if you are 60 to 63).
- You are on a high-deductible health plan and your HSA is funded through payroll, and the money is invested, not sitting in cash.
- You asked HR whether the 401(k) allows after-tax contributions and in-plan Roth conversions.
- You checked for old pre-tax IRA balances before a backdoor Roth, because of the pro-rata rule.
- Your withholding covers bonus and RSU income, or you made an estimated payment.
- You decided whether to bunch two years of gifts into a donor-advised fund.
- If you own a rental, your hour log and average stay math are up to date.
Who this does not work for
- Anyone who needs the cash flow now. Pre-tax savings only help if you can live on what is left.
- Earners whose plan has no after-tax option. The mega backdoor Roth is not available to them.
- People expecting deductions for work costs. Unreimbursed employee expenses are not deductible on a federal return.
- Households with no time for a rental. The large deductions need a property and real hours, or a spouse who can log them.
What changed for W-2 earners in 2026?
- 401(k) limit $24,500, catch-up $8,000 at 50 or older, $11,250 at ages 60 to 63, and a $72,000 total limit.
- HSA limits $4,400 self-only and $8,750 family.
- IRA limit $7,500. The Roth IRA phase-out for married couples runs from $242,000 to $252,000.
- Standard deduction $16,100 single and $32,200 married filing jointly.
- SALT cap $40,400, phasing down above $505,000 of income, under the One Big Beautiful Bill Act.
- Non-itemizers can deduct up to $1,000 of cash gifts to charity, or $2,000 on a joint return.
- 100% bonus depreciation is permanent for property acquired after January 19, 2025, which matters if you buy a rental.

Common questions from W-2 earners
How do I cut my taxes as a W-2 earner making $300K a year without starting a business?
Fill the pre-tax accounts first: up to $24,500 in the 401(k) and up to $4,400 (self-only) or $8,750 (family) in an HSA in 2026. For a single filer at $300,000 that saves about $10,000 of federal tax. Then add a backdoor Roth IRA, a mega backdoor Roth if your plan allows it, and charitable bunching. A short-term rental is the large move if you will run one.
I max my 401k and HSA. What is left?
After-tax 401(k) room converted to Roth, a backdoor Roth IRA, a dependent care FSA, tax-loss harvesting in a taxable account, and charitable bunching through a donor-advised fund. Those need no business, no property, and no spouse. Anything larger needs a rental or business income.
What can a salaried executive in the 37% bracket do?
Max every pre-tax deferral, including deferred compensation if the plan is sound, since each $10,000 saves $3,700 of federal tax. Fix withholding on bonuses and RSUs. Give appreciated stock through a donor-advised fund in high-income years. The SALT cap is usually back to $10,000 at that income, and itemized deductions are worth about 35 cents per dollar starting in 2026.
Can I deduct expenses against my wages?
Almost never. Unreimbursed employee business expenses are not deductible on a federal return. Pre-tax payroll items such as the 401(k), the HSA, health premiums, and the dependent care FSA are the main way to lower wages before they reach the return.
How can W-2 employees deduct rental property losses?
The short-term rental loophole treats a rental with an average stay of 7 days or less as non-passive when you materially participate, usually more than 100 hours and more than anyone else. That takes the loss outside the passive loss limits. Clearing the 7-day test is only half of it. Material participation is a separate test with its own records.
Can I qualify for real estate professional status with a full-time job?
No. The test needs more than 750 hours and more than half of your working time in real estate, and a full-time job makes the second part impossible. A spouse who does not work full time elsewhere is the realistic route on a joint return.
Does the higher SALT cap help W-2 earners in 2026?
It can. The cap rose to $40,400 for 2026, which helps itemizers in high-tax states with income under $505,000. Above that, the cap drops by 30% of the excess and returns to $10,000 at about $606,333 of income.
Does an LLC lower the tax on my salary?
No. An LLC does not change how wages are taxed. Entity choice starts to matter only once you have self-employment or rental income, and even then the S-corp question depends on profit level, payroll cost, and state rules.
