I'm not from U.S but I'd like to know more about it. Please share.How much different the tax before you get married and have child and after?
Would need more info to answer your question like how much your income is, and whether your future spouse has income also.





For a child, you get a $3300 exemption, which means you don't pay taxes on that much of your income, and also $1000 credit taken off your total tax if you owe that much.How much different the tax before you get married and have child and after?
It depends on your income. You get a penalty for being married, but you get a credit for having a child. I think the smallest return you can get is $1000 for a child.
