Autism may be considered a disability for tax purposes if it meets certain criteria. The IRS defines a person as disabled if they cannot engage in any substantial gainful activity due to a physical or mental condition, and a doctor determines that the condition has lasted or can be expected to last continuously for at least a year.
For your grandchild, if a doctor has determined that their autism meets these criteria, you can mark them as disabled on the Dependent info section of your tax return
- You must prove that your grandchild has a permanent or total disability.
- To prove your grandchild's disability, get a letter from their doctor, healthcare provider or any social service program or agency that can verify their disability.
For more detailed information, you can refer to the TurboTax Community and the IRS guidelines on dependents.
