Many of the dollar amounts upon which federal taxes are based must, by law, be adjusted to reflect the impact of inflation.

Not adjusting those value-based provisions within the Internal Revenue Code (IRC) for inflation could cause strange results.

For instance, each year many employees receive a cost-of-living adjustment (essentially an inflation adjustment) to their salary. If the income tax brackets were not also adjusted for inflation, over time the employee who receives only cost-of-living adjustments would be pushed into a higher marginal tax rate even though the real purchasing power of the employee’s salary had not increased.

Inflation adjustments can be found in various pronouncements from the Internal Revenue Service (IRS). The adjustments discussed in this alert can be found in Notice 2022-55 and Revenue Procedure 2022-38. Both are available at www.irs.gov. 

Following are selected inflation adjustments that could impact your tax calculations.

Tax on Net Investment Income

A taxpayer is subject to a tax on net investment income when such taxpayer’s modified adjusted gross income exceeds a certain threshold. The threshold amount for individuals is not indexed for inflation. Table 3 lists the threshold amounts for 2023.

Table 3: 2023 Threshold Amounts on Net Investment Income

Taxpayer Type Threshold Amount (MAGI)
Married Individuals Filing Jointly or Surviving Spouse $250,000

Standard Deduction

When determining taxable income, taxpayers may elect to itemize deductions or take the standard deduction. The Tax Cuts and Jobs Act of 2017 substantially increased the standard deduction, with the result that many more taxpayers are taking the standard deduction rather than itemizing deductions. The standard deduction amount is indexed for inflation. For 2023, the standard deduction amount can be found in Table 5.

Table 5: 2023 Standard Deduction Amounts

Taxpayer Type Standard Deduction

Married Individuals Filing Jointly or Surviving Spouse

$27,700
Heads of Households $20,800

Unmarried Individuals Other than Surviving Spouses and Heads of Households

Married Individuals Filing Separately

$13,850

For 2023, the standard deduction amount for an individual who may be claimed as a dependent cannot exceed the greater of $1,250, or the sum of $400 and the individual’s earned income.

For 2023, the additional standard deduction amount for the aged or the blind is $1,500. The additional standard deduction amount is increased to $1,850 if the individual is also unmarried and not a surviving spouse.

Unearned Income of Minor Children (colloquially known as the Kiddie Tax)

Parents may elect to include a minor child’s income on their own federal income tax return (and not file a separate return for the child) if certain conditions are met including that the child had income only from interest and dividends for the tax year. For 2023, a parent may make this election if the child has gross income between $1,250 (the child’s standard deduction amount as adjusted for 2023) and $12,500. Above that threshold, the child must file a separate return. 

Also, the threshold for taxing a child’s net unearned income at the parent’s rates (the Kiddie Tax) is increased to twice the child’s standard deduction amount or $2,500

See IRS Publication 929 for more details.

Tax Credits

Certain tax credits such as the adoption credit, the child tax credit, the earned income credit and others have phase out amounts and other tests dependent upon income thresholds. The inflation adjustments for these thresholds can be found in Section 3.04 et. seq. of Rev. Proc. 2022-38.

Alternative Minimum Tax

Taxpayers may limit the amount subject to income tax by using deductions, exemptions, losses and tax credits. It is possible to use those items to produce a federal income tax of zero dollars. The alternative minimum tax (AMT) is a separate way of calculating income tax by adding back some of those items (known as tax preference items) to calculate a different base amount on which tax is calculated (alternative minimum taxable income or AMTI).

Although the details are beyond the scope of this alert, a taxpayer’s AMT is the amount by which AMT exceeds regular federal income tax. A certain amount of AMTI is exempt from the AMT, this amount is adjusted annually for inflation (Table 6). AMT exemption amounts are phased out or reduced 25% for each dollar of AMTI over certain threshold amounts. These thresholds are also adjusted for inflation (Table 7). The AMT rate is 26% for taxpayers below and 28% for taxpayers above a threshold amount (Table 8).

Qualified Business Income (QBI); IRC Section 199A

The Tax Cuts and Jobs Act of 2017, enacted IRC section 199A. Owners of passthrough entities, such as partnerships and S corporations, may receive a deduction of up to 20% of qualified business income (QBI) from qualifying pass-through entities.

For taxpayers with taxable income below a threshold amount the full 20% deduction is available. Above that taxable income threshold amount, the deduction phases out. For taxpayers above the maximum taxable income threshold amount engaged in a specified trade or business (SSTB) the QBI deduction is eliminated. For taxpayers above the maximum taxable income threshold amount, not engaged in an SSTB other rules apply to determine the amount of the QBI deduction. The threshold amounts are indexed for inflation (Table 9). 

Table 9: 2023 QBI Deduction Thresholds

Taxpayer Type Threshold Amount Phase-in/Phase-out Amount
Married Individuals Filing Jointly $364,200 $464,200
