How These Changes Impact Your Taxes
The adjustments to tax brackets mean that some taxpayers will pay lower taxes due to increased income thresholds, while others might move into a higher bracket if their income has increased.
Example 1: Lower Taxes Due to Inflation Adjustments
John, a single filer, earned $47,000 in 2024, placing him in the 22% bracket. In 2025, the 12% bracket now covers incomes up to $47,150, meaning he remains in the 12% bracket instead of moving into 22%, saving him money.
Example 2: Higher Taxes Due to Increased Income
Sarah and Mark, a married couple filing jointly, earned $180,000 in 2024, just within the 22% bracket. In 2025, if their income increases to $185,000, they will now be partially in the 24% bracket, meaning a portion of their income is taxed at a higher rate.
Standard Deduction Increases for 2025
The standard deduction has also increased under IRC § 63, reducing taxable income for those who do not itemize deductions.
- Single filers: $15,550 (up from $14,600)
- Married filing jointly: $31,100 (up from $29,200)
- Head of household: $22,700 (up from $21,900)
Taxpayers who take the standard deduction instead of itemizing will benefit from these increases.
Marginal Tax Rates vs. Effective Tax Rates
Many taxpayers misunderstand how tax brackets work. The marginal tax rate is the rate at which your last dollar is taxed, while the effective tax rate is the overall percentage of your income paid in taxes.
Example: Calculating Tax Liability
Emma, a single filer, earns $80,000 in 2025. Her tax liability is calculated as follows:
- First $11,600 taxed at 10% = $1,160
- Next $35,550 ($47,150 – $11,600) taxed at 12% = $4,266
- Remaining $32,850 ($80,000 – $47,150) taxed at 22% = $7,227
Total tax liability = $12,653
Effective tax rate = 15.8% (Total Tax ÷ Total Income)
