Can I get back the money I was penalized for not having health insurance for 2018

[BillM223]

No. The government action that reduced the penalty for failing to have adequate insurance to zero did so for tax year 2019 and going forward.

There is no provision to get refunds for penalties incurred in tax year 2018 and before.
