2015 Tax Brackets

Introduction

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 creep.” 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 an actual 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. Rather than directly adjusting last year’s values for annual inflation, each provision is adjusted from a specified base year. For more information, see the methodology, below.

Estimated Income Tax Brackets and Rates

In 2015, the income limits for all brackets and all filers will be adjusted for inflation and will be as seen in Table 1. The top marginal income tax rate of 39.6 percent will hit taxpayers with taxable income of $413,200 and higher for single filers
and $464,850 and higher for married filers.

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. will increase by $100 from $6,200 to $6,300 for singles (Table 2). For married couples filing jointly, it will increase by $200 from $12,400 to $12,600. The personal exemption for 2015 be $4,000.

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 Senator Donald Pease) reduces 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 point. The income threshold for both PEP and Pease will be $258,250 for single filers and $309,900 for married filers (Tables 3 and 4). The PEP phaseout will end at $380,750 for singles and $432,400
for couples filing jointly, meaning these taxpayers will no longer have a personal exemption.

Alternative Minimum Tax

Since its creation in the 1960s, the Alternative Minimum Tax (AMT) has not been adjusted for inflation. Thus, Congress was forced to “patch” the AMT by raising the exemption amount to prevent middle class taxpayers from being hit by the tax as a result
of inflation. On January 2, 2013, the American Taxpayer Relief Act of 2012 indexed the income thresholds to inflation, preventing the necessity for an annual patch. The AMT exemption amount for 2015 is $53,600 for singles and $83,400 for married couple
filing jointly (Table 5).

Earned Income Tax Credit

2015’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 $503 if the filer has no children (Table 6). For one child the credit is $3,359, two children is $5,548, and three or more children is $6,242.

Source: Author’s calculations. Each tax parameter is adjusted for inflation by taking its base value (from legislation) and multiplying it by the current fiscal year’s average Consumer Price Index (CPI) and then dividing that by the base fiscal
year’s CPI. Each parameter is rounded to either the nearest $10, $25, or $100 (depending on the specified rounding method in the legislation). For example, the base value for the top of the 10 percent tax bracket for singles is $7,000. This number is
multiplied by the average CPI for fiscal year 2014 (235.69) and then divided by the average CPI for fiscal year 2002 (178.68): $7,000 * (235.69/178.68) = $9233. This value is then rounded down to the nearest $25 to yield 2015’s 10 percent tax bracket
of $9,225.
