One full-time job Out of State + One part-time job In-state. How will I be taxed?

CT resident. Next month I will have a full-time WFH job based in Maryland (call it Job A) and a part-time WFH job based in Connecticut (call it Job B). Both are W2 jobs.

 

Married filing jointly (spouse has full-time W2 job in-state). Will we be in the tax bracket that considers my total income A+B as a single income? Or is it not that simple?

 

Also as part of my onboarding paperwork I only received a CT W4. Am I correct in assuming my paychecks will only have state taxes reduced from CT? Will I owe MD come tax time? Basically, I'm in a whirlwind here.

 

I asked my HR person but they're not sure as they're in another state altogether with different tax stipulations.
