The standard deduction amount has been increased for all filers. The amounts are:
Single or married filing separately — $13,850.
Head of household — $20,800.
Married filing jointly or qualifying surviving spouse — $27,700.
Additional child tax credit amount increased. The maximum additional child tax credit amount has increased to $1,600 for each qualifying child.
Child tax credit enhancements. Many changes to the Child tax credit (CTC) that had been implemented by the American Rescue Plan Act of 2021 have expired.
However, the IRS continues to closely monitor legislation being considered by Congress affecting the Child Tax Credit. The IRS reminds taxpayers eligible for the Child Tax Credit that they should not wait to file their 2023 tax return this filing season. If Congress changes the CTC guidelines, the IRS will automatically make adjustments for those who have already filed so no additional action will be needed by those eligible taxpayers.
Under current law, for tax year 2023, the following currently apply:
The enhanced credit allowed for qualifying children under age 6 and children under age 18 has expired. For 2023, the initial amount of the CTC is $2,000 for each qualifying child. The credit amount begins to phase out where AGI income exceeds $200,000 ($400,000 in the case of a joint return). The amount of the CTC that can be claimed as a refundable credit is limited as it was in 2020 except that the maximum ACTC amount for each qualifying child increased to $1,500.
The increased age allowance for a qualifying child has expired. A child must be under age 17 at the end of 2023 to be a qualifying child. https://www.irs.gov/newsroom/tax-time-guide-2024-what-to-know-before-completing-a-tax-return
