What is non-maryland losses and adjustments? Is there a line on the w2 where i can put this information?

Non-Maryland losses and adjustments refers to income or losses that you had in other states while you were not a resident of Maryland that Maryland doesn't tax. 

Examples include (but are not limited to):

- income you earned while living and working in another state that was already taxed by another state

- business losses from a company or property you own in another state

- rental income or losses from property located outside of Maryland

- investment income that was specifically sourced to another state

- retirement distributions that are taxable at the federal level but exempt in Maryland

- interest from bonds issued by other states (which Maryland doesn't tax)

- disaster related losses in another state that qualify for special tax treatment in Maryland
