Filing as married filing jointly gives you a standard deduction of $32,200 for 2026 — exactly double the single deduction of $16,100. The federal brackets are also wider: the 12% bracket extends to $99,700 (vs $49,850 single), and the 22% bracket extends to $212,900 (vs $106,450 single). This generally results in lower taxes when one spouse earns significantly more than the other.
The effective tax rate for married filers in Colorado ranges from 14.0% at $40K to 26.5% at $300K. The wider brackets and doubled deduction mean married filers consistently pay a lower effective rate than single filers at the same gross salary (assuming one earner).
How much difference does filing status make? Here’s a side-by-side at three key salary levels (assuming one earner):
| Salary | Single Take-Home | Married Take-Home | Difference | Monthly Diff |
|---|---|---|---|---|
| $75K | $58,238 | $61,323 | +$3,085 | +$257/mo |
| $100K | $74,725 | $80,310 | +$5,585 | +$465/mo |
| $150K | $107,151 | $116,475 | +$9,324 | +$777/mo |
In Colorado, married filing jointly consistently results in a marriage bonus at these salary levels, averaging $5,998/year. The bonus is largest at higher incomes because the doubled standard deduction and wider brackets shelter more income from higher marginal rates. This analysis assumes one earner — when both spouses have similar incomes, the bonus shrinks or may become a penalty as combined income pushes into higher brackets.
Colorado uses a flat 4.4% state income tax rate regardless of filing status. Unlike the federal system, where married filers get wider brackets, Colorado’s flat rate applies the same percentage to all taxable income. However, Colorado does follow the federal standard deduction for computing state taxable income in most cases, meaning married filers still benefit from the larger deduction at the state level.
