Can I deduct therapy app subscriptions like TalkSpace and BetterHelp as medical expenses?

[ThomasM125]

You can't deduct expenses that are merely beneficial to general health. They must be primarily to alleviate a physical or mental disability or illness. The applications you mention are not mentioned in the IRS literature, so you will have to make your own determination based on the forgoing and the information contained in IRS publication 502:
