Individuals can claim an itemized medical deduction for costs related to the diagnosis, mitigation, treatment, cure or prevention of disease, or any condition affecting any structure or function of the body. The IRS has now made it clear that diagnostic procedures need not be recommended by a doctor in order to be deductible. Also, they can be testing for healthy functioning; they need not be looking for disease. "Diagnosis," while usually determining a medical condition or disease, can also include a determination that a condition is absent. Further, a taxpayer does not have to choose the least costly testing method. Examples: Annual physicals, electronic body scans, and home pregnancy tests.
Bonus: Since the cost of diagnostic tests are a deductible medical expense, they can also be covered under a flexible spending account (FSA), health reimbursement account (HRA), or a health savings account (HSA).
Advance payment of current tax liability based either on wage withholdings or installment payments of your estimated tax liability. To avoid penalties, you generally must pay to the IRS either 90% of your final tax liability, or either 100% or 110% of the prior year’s tax liability, depending on your adjusted gross income.
