For the 2017 tax year, the tax brackets remain the same as in 2016, but the threshold values for each bracket change due to inflation. The lowest bracket (10%) applies to incomes up to $9,325 for individual taxpayers and $18,650 for married couples filing jointly.
Income thresholds for other individual brackets are $37,950 for the 15% bracket, $91,900 for 25%, $191,650 for 28%, $416,700 for 33%, and $418,400 for 35%. For married couples filing jointly, the other thresholds are $75,900 for 15%, $153,100 for 25%, $233,350 for 28%, $416,700 for 33%, and $470,700 for 35%. Individuals with taxable income above $418,400 or couples with taxable income above $470,700 are taxed at the top rate of 39.6%.
For tax year 2018, seven brackets remain but the percentages are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Threshold vales will also change. The results should give most – but not all – Americans some tax relief until these changes expire at the end of 2025. See the 2018 tax brackets online for details.
The 2017 tax year standard deductions are $6,350 for individuals and $12,700 for couples filing jointly. Personal exemptions for 2017 are $4,050 for each taxpayer, spouse, and dependent. The phase-out on personal exemptions begins at $261,500 for individuals, with an upper threshold of $384,000 where the exemption disappears entirely. For married filing jointly, the phase-out begins at $313,800 and ends at $436,300.
For 2018 taxes (the 2019 filing season), both will change dramatically. The standard exemption almost doubles ($12,000 for singles and $24,000 for couples) and the personal exemption disappears entirely. These changes also expire at the end of 2025.
For 2017, the Alternative Minimum Tax (AMT) exemption amounts are $54,300 for individuals and $84,500 for married couples filing jointly. The exemption phases out at $120,700 for individuals and $160,900 for couples. In 2018, the exemption amounts rise to $70,300 for singles and $109,400 for joint filers, while the phase-out limits jump to $500,000 and $1 million respectively.
