Is swimming pool installation tax-deductible?
Swimming pool installation is not deductible as a regular home improvement expense. According to IRS Publication 502, pools installed for personal recreation don't qualify for any tax deductions. However, the $30,000-$80,000 cost gets added to your home's cost basis, reducing future capital gains when you sell.
