Tax credits provide you with money to go toward paying back your owed taxes. For example: Assume that a taxpayer has an income of $100,000 and is unmarried. If they’re filing taxes in 2019 for the 2018 year, they would be placed in the 24% bracket. According to NerdWallet’s federal income tax bracket table, they would owe $14,089.50 plus 24% of their income amount over $82,500, which equates to $4,200. Adding that up, the individual would roughly owe $18,289.50 for their 2018 taxes. If the individual had a 10% tax credit, they would still be in the 24% tax bracket and still owe $18,289.50. However, they’d be given a $10,000 credit, bringing the end payment down to $8,289.50.
