I have high medical expenses, per the services received in December 2019.
So the service date was within 2019, but when receiving the billing statement, it's the end of Dec 2019, and the payment was made in 2020.
Will the medical expense go by the service date or payment date?
say, for my above medical expense, should I report it to year 2019 tax return or year 2020 tax return?
Thanks.
