Mid-year my employer changed names and ownership. The LLC I was working for was transferred to be owned by a larger LLC. So essentially my yearly salary was split between two W-2 forms. 2017 was my first year getting a refund, and I didn't owe anything but in 2018 I ended up owing taxes even though my employer took taxes from every paycheck (not sure how I could owe anything if I'm single and not exempt from any taxes).
I guess I'm wondering if this change affected my return and if I should do something to make it right. Also, I started the year making 65k and it was decreased to 56k due to budget cuts during these company changes.
