I am looking at my 2018 tax projections and had a question on tax credits. With my current income and deductions, the federal government will owe me about $350 in taxes in 2018. My question is how do you determine the credit that pushes you to not have any tax liability? One of the credits I will use is refundable and one is non refundable so just wanted to see if my tax would be zero or if they will owe me $350. For example which way does this work?
Tax liability $2,050
New child tax credit (Lets assume all refundable) -$2,000
Savers tax credit (Non-refundable) -$400
Total (Since savers tax pushes me negative it stays at zero) $0
OR
Tax liability $2,050
Savers tax credit (Non-refundable) -$400
New child tax credit (Lets assume all refundable) -$2,000
Total (Since child tax credit is fundable) -$350
