For 2019, your medical expenses are only deductible as an itemized deduction to the extent they exceed 10 percent of your adjusted gross income. Depending on what your taxable income is expected to be in 2019 and 2020, and whether itemizing deductions would be advantageous for you in either year, you may want to accelerate any optional medical expenses into 2019 or defer them until 2020. The right approach depends on your income for each year, expected medical expenses, as well as your other itemized deductions.
However, health saving accounts (HSAs) present an attractive alternative. If you are eligible to set up such an account, you can deduct the amount you contribute to the account in computing adjusted gross income. Thus, the contributions are deductible whether you itemize deductions or not. Distributions from an HSA are tax free to the extent they are used to pay for qualified medical expenses (i.e., medical, dental, and vision expenses). For 2019, the annual contribution limits are $3,500 for an individual with self-only coverage and $7,000 for an individual with family coverage.
