My temporary employer did not withhold state tax from my paychecks for the 6 months I worked in 2016. I got them to make the correction to the W2. Shouldn't there be something else done to send in the taxes that should have been withheld before the tax year 2016 ends? My employer is telling me to just file next year with the corrected W2 which wont be available until 2017. But that will leave me with a big state (Maryland) tax bill and a penalty, won't it?
