That big tax law that was signed late in 2017 means you can expect to see major changes this year, when you file your taxes for 2018.

Married couples filing jointly will see an increase from $12,700 to $24,000, and heads of households will see a jump in their standard deduction from $9,350 to $18,000.

To ease some of the sting for parents, the law has doubled the child tax credit from $1,000 to $2,000. It also created a new $500 credit for a qualifying dependent who is not a child.
