IRS updates 2026 income tax brackets: Married couples vs single filers - What's the difference?

The United States Internal Revenue Service (IRS) has released updated federal income tax brackets for the 2026 tax year, with changes aimed at accounting for inflation. These annual adjustments prevent ‘bracket creep’, when rising wages push taxpayers into higher tax brackets despite their real purchasing power not increasing.

The new brackets, announced on Thursday, will apply to tax returns filed in 2027. Both married couples filing jointly and single filers will see higher income thresholds before reaching the next tax bracket, meaning taxpayers may owe less than they would have under 2025 levels.

According to CNBC, married couples will now be charged the 10 percent tax on incomes from $0 to $24,800 instead of $23,850 in 2025. Moreover, the 12 percent tax rate will apply to earnings from $24,801 to $100,800, which is a 4,000-dollar increase from $96,950 in 2025.

The highest taxation level of 37 percent will now start at the income of $768,701 and above, as against $751,601 in 2025.

This also implies that a couple with a combined gross income of $150,000 will have a lower effective rate due to the adjustments in the brackets and the higher deduction for the standard amount.

CBS has reported that the 10 percent bracket for single filers will be on the first $12,400 of income, which is an increase from $11,925 in 2025. The 12 percent tax code will cover up to $50,400, which is a jump from $48,475 in the previous year. The highest tax rate is that of 37 percent which is applicable on incomes of $640,601, as compared to $626,351 in 2025.

To illustrate, a single taxpayer making $50,000 would be taxed at the 12 percent rate on the bulk of their income, but that is after the initial $12,400 has been taxed at the 10 percent rate.

Moreover, older people might take advantage of a temporary deduction that can go up to $6,000 through 2028 for those earning at most $75,000 (single) or $150,000 (married couples).

For 2026, the 10 percent bracket covers incomes up to $24,800, while the top 37 percent rate applies at $768,701 and above.
