US Tax Brackets and Deductions for 2017

Overview of 2017 US Tax Brackets

Taxable income encompasses earnings from employment, rental properties, awards, investments, gambling, or business activities. It excludes educational funds, gifts, inheritances, accident payments, or workers' compensation.

For 2017, tax brackets are divided into seven levels, each taxed at a distinct rate. The IRS adjusts these brackets annually for inflation, a process known as "bracket creep," which can shift taxpayers into higher tax categories or diminish credits and deductions without actual income growth.

Determining 2017 Tax Brackets

The IRS bases income thresholds on the Consumer Price Index (CPI), reflecting inflation and living costs. Rising CPI causes tax brackets to shift, potentially lowering your tax rate if your income remains unchanged.

2017 Income Brackets

The maximum tax rate of 39.6% applies to incomes exceeding $418,400 for single filers and $470,700 for married couples filing jointly. Income limits for all brackets are annually adjusted for inflation.

The standard deduction for 2017 increases to $6,350 for singles and $12,700 for joint filers. Personal exemptions stay at $4,050. High earners may face phase-outs from provisions like PEP and Pease, which reduce deductions and exemptions once income surpasses specific thresholds, now at $261,500 for singles and $318,800 for couples.
The Alternative Minimum Tax (AMT) aims to ensure high-income taxpayers pay minimum taxes, requiring calculations under two systems. In 2017, the AMT exemption is set at $54,300 for singles and $84,500 for couples, with rates of 26% and 28%. The exemption phases out as income rises beyond $120,700 for singles and $160,900 for couples.

Tax credits, such as the Earned Income Tax Credit, increase slightly in 2017, offering up to $6,318 for taxpayers with three or more children. Other credits and deductions help minimize taxable income, which is calculated after personal exemptions and standard or itemized deductions.

Understanding that tax brackets apply to taxable income—not gross income—is crucial. Strategic pre-tax contributions to retirement accounts can further reduce taxable income. As brackets are inflation-adjusted, planning ahead can help optimize tax outcomes.

In summary, 2017's tax landscape involves multiple brackets influenced by CPI, with provisions like PEP, Pease, and AMT shaping tax liability. Staying aware of these factors allows taxpayers to make informed financial decisions each year.
