Married vs. Single: How Filing Status Changes Your Pay

Your filing status quietly changes how much of every paycheck you keep. For 2026 the married standard deduction ($32,200) is exactly double the single one ($16,100), and the married tax brackets are wider — so the same salary can be taxed very differently depending on the box you check. Here is what actually changes, with the math.

The single-income "marriage bonus"

When one spouse earns most or all of the income, marriage usually lowers the tax bill. The couple gets two people's worth of deductions and brackets applied to one income. Here is the same salary filed single vs. married filing jointly, in a no-income-tax state (Texas), so you see only the federal effect:

Salary	Take-home: single	Take-home: married	Difference
$60,000	$50,390	$52,570	+$2,180/yr
$90,000	$72,145	$76,675	+$4,530/yr
$150,000	$113,791	$123,185	+$9,394/yr

At $90,000 on a single income, filing jointly puts roughly $4,530 a year back in the household's pocket — purely from the wider married brackets and doubled deduction.

State taxes amplify the effect

In a state with graduated brackets, the gap widens because the state deduction and brackets also roughly double. Take the same $90,000 single-income earner in California: filing single leaves about $67,852, while married filing jointly leaves about $74,790 — a difference of $6,939 a year, on top of the federal benefit. Compare any state for yourself in the 2026 calculator (it has a married/single toggle).

When marriage costs you: the "marriage penalty"

The bonus flips when both spouses earn similar high incomes. Two earners can be pushed into higher combined brackets than they would hit separately, and at the very top the married bracket thresholds are not quite double the single ones. For most middle-income couples — and almost all single-income households — marriage helps. It is high, dual-income couples who can face a penalty.
