Swimming Pool
One man successfully deducted $4,000 to build an indoor swimming pool in his home because he said it would help alleviate his arthritis symptoms, according to
TurboTax. If you have a medical condition or injury and a dip in the pool could help, you may be able to write off a swimming pool as a tax deduction. Not everyone attempting to use this deduction has been successful, however. The IRS has denied other taxpayers the deduction when their medical necessity was not as clear.
