2026 State-by-State Guide: Where You'll Pay the Steepest Marriage Penalty
By Niche Calculators Updated March 2026
You've planned the honeymoon, merged your bank accounts, and changed your name on social media. But if you live in the wrong state, saying "I do" could cost you over $8,000 a year.
The Tax Cuts and Jobs Act of 2017 largely eliminated the marriage penalty at the federal level by doubling the standard deduction and widening tax brackets for joint filers. But here's the catch: your state doesn't have to play by the same rules.
At least 18 states and Washington D.C. still impose a marriage penalty in 2026. That means dual-income couples pay more filing jointly than they would as two single people.
Today, I'm breaking down exactly where the penalty hits hardest—and what you can do about it.
How the Marriage Penalty Works (A Quick Refresher)
Before we dive into the rankings, let's understand the mechanics.
The marriage penalty occurs when state income tax brackets for married couples are not exactly double the width of single filer brackets. When two earners with similar salaries combine their incomes, they get pushed into higher marginal tax brackets faster than they would as two individuals.
Who gets hit hardest? Dual-income households where both partners earn similar wages. A couple earning $75,000 each faces a very different tax bill than a couple where one spouse earns $150,000 and the other stays home.
The standard deduction also plays a role. In the analysis below, researchers used a standard deduction of $15,750 for married filing separately and $31,500 for married filing jointly—the projected 2026 figures.
The 2026 Marriage Penalty Rankings: Worst Offenders
Data source BestBrokers analysis of a dual-income couple earning $75,000 each annually, using 2026 standard deduction projections. Cited by USA Today, Yahoo Finance, and The Economic Times.
🔴 Tier 1: The "Over $5,000" Club (Severe Penalty)
#1: Washington, D.C. – $8,173 Penalty
The Cost: A married couple with two $75,000 incomes pays an extra $8,173 per year compared to filing as two singles.
Why: Washington D.C.'s progressive tax brackets create severe compression at moderate income levels. The district's bracket structure simply doesn't scale fairly for joint filers.
"Washington, DC, imposes the steepest marriage penalty, costing a married couple an extra $8,173 annually compared to two individual filers." — Paul Hoffman, Editor in Chief at BestBrokers
If you're engaged in the nation's capital, this is your wake-up call.
#2: Delaware – $7,008 Penalty
The Cost: $7,008 extra for married couples.
Why: Delaware's bracket structure doesn't proportionally scale for joint filers. The interaction between progressive rates and standard deductions creates a significant disadvantage for dual-income couples.
Delaware consistently ranks among the worst states for marriage penalties—and 2026 is no exception.
#3: West Virginia – $5,724 Penalty
The Cost: $5,724 additional tax burden.
Why: Similar to Delaware, West Virginia's progressive brackets and deduction rules penalize couples with similar earnings. If you and your fiancé both work in Charleston or Morgantown, run the numbers before you file jointly.
🟠 Tier 2: The "Over $1,000" Club (Moderate Penalty)
These states won't break the bank like the top three, but they'll still cost you.
| Rank | State | Penalty Amount |
|---|---|---|
| #4 | New Mexico | $2,146 |
| #5 | Rhode Island | $1,834 |
| #6 | New Jersey | $1,575 |
| #7 | Wisconsin | $1,469 |
| #8 | Ohio | $1,364 |
| #9 | Virginia | $1,318 |
| #10 | South Carolina | $1,212 |
| #11 | Minnesota | $1,191 |
| #12 | Vermont | $1,046 |
Ohio's Unique Case: Tax expert and former Ohio State Representative John Becker explains why his state appears on this list:
"Ohio's so-called 'flat tax' for Tax Year 2026 is not truly flat due to the zero percent tax bracket. An unmarried couple both making minimum wage would owe zero Ohio tax as singles, but if they married, they'd face a $766 penalty due to the zero percent rate ending at $26,050."
🟡 Tier 3: The "Under $1,000" Club (Minor Penalty)
These states technically penalize marriage, but the impact is minimal—at least for the average dual-income couple.
| Rank | State | Penalty Amount |
|---|---|---|
| #13 | Missouri | $857 |
| #14 | Mississippi | $440 |
| #15 | North Dakota | $312 |
| #16 | Maryland | $253 |
| #17 | Arkansas | $86 |
| #18 | Nebraska | $1 |
Nebraska's $1 Penalty: Yes, that's correct—one dollar. It's technically a penalty, but it's unlikely to change your wedding plans.

The One State Where Marriage Pays: New York's Tiny Bonus
Every list needs an outlier.
New York is the only state where married couples come out ahead of two single filers in this analysis, with a $23 marriage bonus.
It's not much—barely enough for a nice dinner—but it's notable. It means New York's brackets are structured to slightly favor joint filers at this income level.
"In practice, some couples file jointly even when only one spouse works, which can amplify the marriage penalty or bonus depending on the state." — BestBrokers analysis
Deep Dive: Why These States Penalize Marriage
The "Bracket Compression" Problem
When states design progressive tax systems, they often set the top of each bracket for joint filers at less than double the single amount. This pushes couples into higher rates sooner than two individuals with the same combined income.
The Deduction Disconnect
Some states don't double the standard deduction for joint filers, or they phase out deductions at lower income thresholds for couples. This creates an immediate disadvantage before you even calculate brackets.
Washington State's Proposed $40,000 Penalty
Heads up, Washingtonians: Your state doesn't currently have an income tax, so it's not on this list. But proposed legislation (SB 6346) would impose a 9.9% tax on income above $1 million—with a marriage penalty built in.
Here's the math:
- Two singles each earning $700,000: $0 tax
- A married couple earning $1.4 million combined: Nearly $40,000 tax
If this passes, Washington could jump to the top of the rankings overnight.
Beyond State Income Tax: Other Federal Marriage Penalties to Watch
- Capital Gains Tax – 15% rate applies up to $533,400 for singles but only $600,050 for couples—not double. 20% above.
- Net Investment Income Tax (NIIT) – 3.8% tax begins at $200,000 for singles, $250,000 for couples.
- Additional Medicare Tax – 0.9% surtax starts at $200,000 (single) vs. $250,000 (joint).
- Social Security Taxation – Benefits taxable when combined income exceeds $25,000 (single) vs. $32,000 (joint).
- Child and Dependent Care Credit – Phase-out begins at $15,000 AGI. Married couples combine incomes.
How to Fight the Marriage Penalty in Your State
Strategy 1: Consider "Married Filing Separately"
In penalty states, running the numbers for Married Filing Separately (MFS) might save money. Trade-off: lose eligibility for Roth IRA, education credits, child tax benefits, student loan interest deduction. Ohio Example: John Becker notes that Ohio couples could file separately to eliminate the state penalty, but that would make them ineligible for federal credits.
Strategy 2: Adjust Your Withholding
File a new W-4 with your employer now to avoid a surprise bill.
Strategy 3: Maximize Pre-Tax Contributions
Increase 401(k) and HSA. Lower AGI = lower penalty.
Strategy 4: Tax-Loss Harvesting
Sell losing positions to offset capital gains.
Strategy 5: Relocation Considerations
For D.C., Delaware, West Virginia, an $8,000 annual penalty adds to long-term planning.
