Early retirement has a glossy shine—beaches, hikes, side projects, and no alarm clocks. But step off the traditional work treadmill and the IRS might be waiting with an unexpected bill. Many people in the Financial Independence, Retire Early (FIRE) movement take sabbaticals, either between jobs or before fully retiring, and assume less work means less tax drama.

The truth is, stepping away from work can trip tax landmines most never consider. Here are nine cases where your year off can end with an unwelcome letter from Uncle Sam.

1. The Healthcare Subsidy Clawback

Many FIRE fans bank on Affordable Care Act subsidies to keep insurance cheap during a sabbatical. But subsidies are income-tested, and dipping into retirement accounts can bump income higher than planned. If that happens, subsidies already used get clawed back at tax time. A single withdrawal or capital gain can erase thousands in credits. Suddenly, the “cheap healthcare” year costs more than a full year of premiums.

2. Early Retirement Account Withdrawals

That 401(k) or IRA balance looks tempting when you’re not bringing in a paycheck. But withdrawals before age 59½ often trigger a 10% penalty on top of regular income tax. Even “small” withdrawals for a short sabbatical can spiral into a hefty charge. Some strategies, like the Rule of 55 or Substantially Equal Periodic Payments, exist, but miss one detail, and penalties still apply. The IRS doesn’t care if you’re “taking a break” or “retired early”—rules are rules.

3. State Residency Surprises

Some FIRE travelers hop states during sabbaticals, not realizing that states have their own residency definitions. Leaving mid-year can create tax bills in two states for the same income. Even worse, high-tax states like California may still consider you a resident if ties remain strong. Rent out your old house? Keep a driver’s license? That may count. The “freedom to roam” can quietly turn into “double taxation.”

4. Capital Gains Bracket Traps

Selling stock during a sabbatical seems smart since income is low. But tax brackets don’t just depend on wages—they count all income, including capital gains. Push just slightly too far, and long-term gains get taxed at higher rates than expected. This is especially sneaky when Roth conversions or side hustles are in the mix. What looked like a 0% gain year can flip into a tax-bomb year overnight.

5. Social Security Taxation Shock

Even if FIRE is decades away from traditional retirement, some take sabbaticals closer to Social Security age. Benefits might be reduced or taxed if additional income sneaks in during the break. Up to 85% of benefits can suddenly become taxable. Selling property, converting accounts, or freelancing during a sabbatical may trigger this without warning. Early retirement freedom turns into a surprise Social Security haircut.

6. Roth Conversion Gone Wrong

Many FIRE adherents use sabbaticals for Roth conversions since income is lower. But conversions add directly to taxable income. Push too far and suddenly tax credits, healthcare subsidies, and low brackets vanish. Even worse, high conversion amounts can trigger alternative minimum tax complications. That “smart tax move” can backfire into a five-figure IRS bill if not carefully balanced.

7. Net Investment Income Tax Sneak Attack

Think stepping away from work means no payroll taxes? Not exactly. High investment income during a sabbatical can trigger the 3.8% Net Investment Income Tax. It applies to dividends, capital gains, and interest once income crosses certain thresholds. Many underestimate how easily passive income stacks up during a year off, leaving them with a surprise add-on tax.

8. Rental Property Pitfalls

Plenty of FIRE followers use rentals to cover costs during a sabbatical. But income from rentals counts as taxable, and deductions only go so far. Selling a property mid-sabbatical and depreciation recapture can take a huge bite. Even travel away from rentals can trigger “material participation” questions, reducing deductions. That laid-back landlord lifestyle can end in a very unrelaxed tax return.

9. Foreign Travel and Taxation Twists

Extended sabbaticals abroad often tempt FIRE enthusiasts, but foreign residency brings new tax headaches. The Foreign Earned Income Exclusion doesn’t help with passive or investment income. Bank accounts abroad may require reporting to the IRS under strict rules. Miss a form and penalties are brutal, even if no tax is due. A dreamy year abroad can turn into a nightmare of international tax paperwork.

Tax Surprises Don’t Take Sabbaticals

FIRE sabbaticals sound like an oasis of freedom, but taxes follow no matter where the break takes you. Whether it’s healthcare clawbacks, early withdrawals, or state residency rules, the system is designed to keep its cut. Planning a sabbatical without mapping the tax terrain is like hiking barefoot through cactus. The key isn’t to avoid breaks—it’s to understand the traps and plan around them.
