never heard that, but it’s sage.
When you sell real estate in Maryland and are not a resident of the State of Maryland, you need to be aware of the non-resident withholding tax. Since 2003, the State of Maryland has mandated the withholding of income tax on the sale of all real property by non-resident individuals and non-resident entities. The settlement company is required to collect the tax at closing and remit payment along with the deed recording. As of 2019, the withholding tax is 7.5% for non-resident individuals and 8.25% for non-resident entities.
