The STR loophole allows short-term rental investors in Colorado to treat rental losses as non-passive income, enabling them to offset W-2 wages and other active income. Combined with Colorado's 4.4% flat state income tax, total potential savings can exceed 40% of offset income.
What is the STR Loophole?
A tax strategy combining the IRS 7-day rental exception with material participation requirements. If your short-term rental has an average stay of 7 days or less AND you materially participate (100-500 hours), losses can offset W-2 income—not just passive income.
