Personal Exemption
Personal Exemption
A personal exemption is a fixed dollar amount that taxpayers were generally allowed to subtract from their adjusted gross income (AGI) for themselves and each of their dependents, directly reducing the amount of income subject to federal income tax.
How It Works
Before the Tax Cuts and Jobs Act (TCJA) of 2017, the personal exemption was a standard deduction applied per person in a household. Taxpayers could typically claim one exemption for themselves, one for a spouse (if filing jointly), and one for each qualifying dependent. The exemption amount was adjusted annually for inflation.
In tax year 2017, the personal exemption amount was $4,050 per person. A married couple filing jointly with two children could claim four exemptions, reducing their taxable income by $16,200 before any other deductions were applied.
However, the TCJA suspended the personal exemption entirely for tax years 2018 through 2025. The exemption amount is effectively $0 during this period. The law offset this change by nearly doubling the standard deduction and expanding the Child Tax Credit. Unless Congress takes further action, the personal exemption is scheduled to potentially return after 2025 when several TCJA provisions are set to expire.
Why It Matters
Understanding the personal exemption is important for several reasons:
- It remains relevant for taxpayers amending returns from 2017 or earlier tax years.
- State income taxes in many states still use a version of the personal exemption, so it continues to affect state-level tax liability.
- Tax planning after 2025 may need to account for a possible return of the exemption at the federal level.
- Historical tax records, financial planning documents, and older tax software references often include personal exemption calculations.
Practical Examples
Example 1: Pre-2018 Single Filer
In 2017, a single taxpayer with an AGI of $45,000 could claim one personal exemption of $4,050. After subtracting that exemption (and assuming they also took the standard deduction of $6,350), their taxable income would be reduced to approximately $34,600. The exemption alone saved this taxpayer roughly $608 in federal taxes, based on a 15% marginal rate.
Example 2: State Tax in the Present Day
Many states, including Michigan and Pennsylvania, continue to offer personal exemptions on state income tax returns. In Michigan, for example, the personal exemption for 2023 was generally $5,400 per person. A family of four filing a Michigan state return could typically reduce their state taxable income by $21,600 through exemptions alone, even though no comparable federal exemption exists.
Important Limitations
Even when the personal exemption was in effect at the federal level, it was subject to a phaseout for higher-income taxpayers. This phaseout, sometimes called the Pease limitation or the exemption phaseout rule, reduced the value of exemptions for individuals whose income exceeded certain thresholds. In most cases, taxpayers with very high incomes received little to no benefit from the exemption.
Related Tax Concepts
Readers interested in the personal exemption may also want to explore these closely related topics:
- Standard Deduction: The flat amount most taxpayers subtract from income instead of itemizing, which was significantly increased when the personal exemption was suspended.
- Dependent Exemption: A component of the personal exemption system that applied to qualifying children and relatives claimed on a return.
- Child Tax Credit: A credit that partially replaced the tax benefit lost when exemptions for dependents were eliminated.
- Adjusted Gross Income (AGI): The income figure from which exemptions and deductions are generally subtracted.
- Tax Cuts and Jobs Act (TCJA): The 2017 legislation that suspended the federal personal exemption through 2025.
