2017 Tax Brackets

Every year, the IRS adjusts more than 40 taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. provisions for inflationInflation is when the general price of goods and services increases across the economy, reducing the purchasing power of a currency and the value of certain assets. The same paycheck covers less goods, services, and bills. It is sometimes referred to as a “hidden tax,” as it leaves taxpayers less well-off due to higher costs and “bracket creep,” while increasing the government’s spending power. . This is done to prevent what is called “bracket creepBracket creep occurs when inflation pushes taxpayers into higher income tax brackets or reduces the value of credits, deductions, and exemptions. Bracket creep results in an increase in income taxes without an increase in real income. Many tax provisions—both at the federal and state level—are adjusted for inflation. .” This is the phenomenon by which people are pushed into higher income tax brackets or have reduced value from credits or deductions due to inflation, instead of any increase in real income.

The IRS uses the Consumer Price Index (CPI) to calculate the past year’s inflation and adjusts income thresholds, deduction amounts, and credit values accordingly.[1]

Estimated Income Tax BracketsA tax bracket is the range of incomes taxed at given rates, which typically differ depending on filing status. In a progressive individual or corporate income tax system, rates rise as income increases. There are seven federal individual income tax brackets; the federal corporate income tax system is flat. and Rates

Standard Deduction and Personal Exemption

The standard deductionThe standard deduction reduces a taxpayer’s taxable income by a set amount determined by the government. It was nearly doubled for all classes of filers by the 2017 Tax Cuts and Jobs Act (TCJA) as an incentive for taxpayers not to itemize deductions when filing their federal income taxes. for single filers will increase by $50 and $100 for married couples filing jointly (Table 4).

The personal exemption for 2017 remains the same at $4,050.

Single	$6,350

PEP and Pease

PEP and Pease are two provisions in the tax code that increase taxable incomeTaxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income. for high-income earners. PEP is the phaseout of the personal exemption and Pease (named after former U.S. House Representative Donald Pease) phases out the value of most itemized deductions once a taxpayer’s adjusted gross incomeFor individuals, gross income is the total pre-tax earnings from wages, tips, investments, interest, and other forms of income and is also referred to as “gross pay.” For businesses, gross income is total revenue minus cost of goods sold and is also known as “gross profit” or “gross margin.” reaches a certain amount.

The income threshold for both PEP and Pease will increase from last year to $261,500 for single filers and $318,800 for married couples filing jointly (Tables 5 and 6). PEP will end at $384,000 for singles and $436,300 for married couples filing jointly (both will increase from 2016), meaning that taxpayers with AGI above these limits will no longer benefit from personal exemptions.

Alternative Minimum Tax

The Alternative Minimum Tax (AMT) was created in the 1960s to prevent high-income taxpayers from avoiding the individual income tax. This parallel tax income system requires high-income taxpayers to calculate their tax bill twice: once under the ordinary income tax system and again under the AMT. The taxpayer then needs to pay the higher of the two.

The AMT uses an alternative definition of taxable income called Alternative Minimum Taxable Income (AMTI). To prevent low- and middle-income taxpayers from being subject to the AMT, taxpayers are allowed to exempt a significant amount of their income from AMTI. However, this exemption phases out for high-income taxpayers. The AMT is levied at two rates: 26 percent and 28 percent.

The AMT exemption amount for 2017 is $54,300 for singles and $84,500 for married couples filing jointly (Table 7).

Table 7. 2017 Alternative Minimum Tax Exemptions

Filing Status	Exemption Amount
Single	$54,300
Married Filing Jointly	$84,500
Married Filing Separately	$42,250
Trusts & Estates	$24,100

In 2017, the 28 percent AMT rate applies to excess AMTI of $187,800 for all taxpayers ($93,900 for unmarried individuals).

Under current law, AMT exemptions phase out at 25 cents per dollar earned once taxpayer AMTI hits a certain threshold. In 2017, the exemption will start phasing out at $120,700 in AMTI for single filers and $160,900 for married taxpayers filing jointly (Table 8.

Single	$120,700
Married Filing Jointly	$160,900

Earned Income Tax Credit

2017’s maximum Earned Income Tax CreditA tax credit is a provision that reduces a taxpayer’s final tax bill, dollar-for-dollar. A tax credit differs from deductions and exemptions, which reduce taxable income rather than the taxpayer’s tax bill directly. for singles, heads of households, and joint filers is $510, if the filer has no children (Table 9). The credit is $3,400 for one child, $5,616 for two children, and $6,318 for three or more children. All of the aforementioned are relatively small increases from 2016.
