I separated my returns and filed my Federal return three weeks ago. I printed and mailed my MD state return two weeks ago, but MD Tax Revenue office didn't receive it. I contacted the revenue office and they told me it could take 4-8 weeks to process a mail in return. However, the revenue office did suggest that I file an electronic version of my MD -502 form directly through the MD Tax Revenue office [iFile - Maryland State Tax]. This process takes only five days to complete.
