7 Tax Myths High Earners Still Believe

Myth 1: 'I Can't Deduct Rental Losses Against My W-2 Income'

This is the most expensive myth in real estate tax planning. It's true that long-term rental losses are generally passive and can't offset W-2 income (under IRC §469). But short-term rentals with average stays of 7 days or less are EXCLUDED from the passive activity rules entirely (Reg. §1.469-1T(e)(3)(ii)). If you materially participate (100+ hours, more than anyone else), your STR losses are non-passive and directly offset your salary. For a high earner with a $750K+ STR and cost segregation, this can mean $40K-$80K in first-year tax savings against W-2 income.

Myth 2: 'Bonus Depreciation Expired'

This was true for about 6 months. The TCJA phased bonus depreciation down to 40% for 2025, and it would have hit 20% in 2026. But OBBBA (signed July 4, 2025) restored 100% bonus depreciation permanently for property acquired after January 19, 2025. If someone told you bonus depreciation was dead, they're working from outdated information. It's fully back and more powerful than ever because there's no scheduled phase-down.

Myth 3: 'My CPA Handles Everything'

Most CPAs are excellent at compliance, accurately filing your return based on what you tell them. But many are not proactive strategy advisors. A typical CPA engagement doesn't include modeling 50+ strategies against your specific income, testing scenario combinations, or proactively recommending cost segregation or entity restructuring. This isn't a criticism of CPAs: it's a description of how most engagements are scoped. Strategy identification is a different function from tax preparation, and most high earners aren't getting both.

Myth 4: 'An S-Corp Will Save Me 15.3% in Self-Employment Tax'

The S-Corp election saves you the 12.4% Social Security tax on distributions above a reasonable salary, but only up to the Social Security wage base ($176,100 in 2026). Above that threshold, the only SE tax is the 2.9% Medicare tax (plus 0.9% Additional Medicare Tax above $200K/$250K). So the realistic savings for a high earner are: 2.9% × (total income − reasonable salary), plus 0.9% on amounts above the threshold. On $500K of 1099 income with a $200K salary, the S-Corp saves ~$8,700 in Medicare taxes, significant, but not the 15.3% that gets thrown around.

Myth 5: 'Buying a Rental Property Is Automatically a Tax Write-Off'

Buying a rental property alone doesn't reduce your taxes. The property must generate a net tax loss (expenses + depreciation > income) AND that loss must be usable against your other income. Without material participation in an STR (or REPS for long-term rentals), the loss is passive and only offsets passive income. Without cost segregation, the standard depreciation on a $750K property is only ~$21K/year, often not enough to create a loss after accounting for rental income. The strategy works when you combine the right property, the right depreciation acceleration, and the right activity classification.

Myth 6: 'The Backdoor Roth IRA Is Going Away'

This rumor has circulated since 2021 when the Build Back Better Act proposed eliminating it. But BBB didn't pass, and OBBBA did not close the backdoor Roth. As of 2026, the strategy is fully legal: contribute $7,000 to a non-deductible traditional IRA, then convert to Roth immediately. The key risk is the pro-rata rule (IRC §408(d)(2)): if you have existing pre-tax IRA balances, part of the conversion is taxable. The fix: roll pre-tax IRA balances into your 401(k) before converting.

Myth 7: 'Tax Planning Is Only Worth It Above $1M Income'

The strategies with the biggest dollar impact (cost segregation, STR strategy, entity restructuring) are most impactful above $300K, not $1M. At $400K MFJ, you're already in the 35% federal bracket. A $100K cost seg deduction saves $35K. Add state taxes and you're at $40K+. Retirement optimization (maxing 401k, backdoor Roth, HSA) starts saving meaningful money at $150K+. The $1M threshold is a myth that keeps $300K-$800K earners from exploring strategies they'd benefit from.
