Exemptions have been eliminated, and the standard deduction has increased to $12,000 for single individuals and $24,000 for married couples.
AMT exemptions and phase-outs have increased. Child tax credit has increased to $2,000 for each child (up from $1,000), with a smaller portion being refundable and with a higher phase out at $400,000 for joint filers.
Allowable itemized deductions have changed, with medical expenses being subject to the 7.5% threshold until the end of 2018. State and local taxes are limited to $10,000 per return. Interest payments are only deductible for home mortgages up to $750,000, with no deductibility for home equity lines of credit. Miscellaneous itemized deductions are no longer allowable.
