Madison Trust: What Is the Most Taxed State in 2026?

Oct 22, 2026



Sioux Falls, South Dakota Oct 21, 2026 (Issuewire.com) - If you're considering where to live, work, retire, or invest, taxes can play a major role in your financial future. However, determining the most taxed state in the U.S. isn't typically as simple as looking at income tax rates alone. 

Sales taxes, property taxes, and state income taxes can all influence how much residents pay. The research team at Madison Trust analyzed which states had the highest and lowest Tax Index scoes using data collected from TaxFoundation.org. 

When all three categories are considered together, California ranks as the most taxed state with a tax index score of 86.3. 

The infographic breaks down all 50 states--and Washington, D.C. --compared across sales, property, and income tax.

What Is the Most Taxed State?

According to the data used for this analysis, California is considered the most taxed state in the U.S., ranking number one with a Tax Index score of 86.3.

California has:

  • 7.25% state sales tax
  • 1.74% average local sales tax
  • 8.99% combined state and local sales tax
  • 0.70% effective property tax
  • 13.30% top marginal state income tax 

Based on the methodology used in this analysis, California has the highest overall Tax Index score.

How Is the Most Taxed State Determined?

The Tax Index in the infographic considers three major types of state and local taxes: 

  • Combined state and local sales tax
  • Effective property tax
  • Top marginal state income tax

Each category is normalized to create a common comparison scale. The highest state in each category receives a score of 100, while other states receive proportional scores. 

The final Tax Index uses the following weighting: 

  • State & Local Sales Tax: 50% of the final Tax Index score
  • Property Tax: 25% of the final Tax Index score
  • State Income Tax: 25% of the final Tax Index score

This means state and local sales taxes have the greatest influence on the overall Tax Index, accounting for half of the total score. Property taxes and state income taxes each contribute one-quarter of the final score.

What Are the Top 10 Most Taxed States?

Based on the Tax Index scores in the infographic, the 10 highest-ranked states are:

1. California -- Tax Index Score: 86.3

2. New Jersey -- Tax Index Score: 78.0

3. New York -- Tax Index Score: 73.6

4. Illinois -- Tax Index Score: 72.9

5. Minnesota -- Tax Index Score: 68.4

6. Washington -- Tax Index Score: 66.8

7. Connecticut -- Tax Index Score: 61.8

8. Kansas -- Tax Index Score: 60.4

9. Wisconsin -- Tax Index Score: 58.8

10. Vermont -- Tax Index Score: 58.3

According to this Tax Index, California ranks first with a score of 86.3, followed by New Jersey at 78.0 and New York at 73.6.

What State Has the Highest Sales Tax? 

Louisiana has the highest combined state and local sales tax rate at 10.11%. Louisiana has a 5.00% state sales tax and 5.11% average local sales tax, for a combined rate of 10.11%. This distinction is considered important as a state that has a modest state sales tax rate can still have high overall sales tax once local taxes are included. 

Which States Have the Highest Combined Sales Tax?

1. New Jersey -- Effective Property Tax Rate: 1.88%

2. Illinois -- Effective Property Tax Rate: 1.88%

3. Connecticut -- Effective Property Tax Rate: 1.54%

4. Vermont -- Effective Property Tax Rate: 1.51%

5. New Hampshire -- Effective Property Tax Rate: 1.50%

Which State Has the Highest Property Tax? 

New Jersey and Illinois have the highest effective property tax rate at 1.88%. The analysis uses mean effective property tax rates on owner-occupied housing, excluding property taxes paid by businesses, renters, and others. 

Which States Have the Highest Property Tax?

1. New Jersey -- Effective Property Tax Rate: 1.88%

2. Illinois -- Effective Property Tax Rate: 1.88%

3. Connecticut -- Effective Property Tax Rate: 1.54%

4. Vermont -- Effective Property Tax Rate: 1.51%

5. New Hampshire -- Effective Property Tax Rate: 1.50%

Which State Has the Highest Income Tax?

California has the highest top marginal state individual income tax rate at 13.30%. The 13.30% represents the top marginal income tax rate, not the percentage every California resident pays on their income. A marginal tax rate applies only to income within a particular tax bracket. 

Which States Have the Highest Income Tax? 

1. California -- Top Marginal Income Tax Rate: 13.30%

2. Hawaii -- Top Marginal Income Tax Rate: 11.00%

3. New York -- Top Marginal Income Tax Rate: 10.90%

4. New Jersey -- Top Marginal Income Tax Rate: 10.75%

5. District of Columbia -- Top Marginal Income Tax Rate: 10.75%

Which States Have No State Income Tax? 

Not every state imposes an individual income tax on wage and salary income. In 2026, states without an individual income tax include Alaska, Florida, Nevada, South Dakota, Texas, and Wyoming. Additionally, Tennessee has no income taxes for earned income, but taxes dividend and interest income. Likewise, Washington does not tax on earned income, but taxes on capital gains income only. 

A state having no individual state income tax typically does not automatically make it a low-tax state. For example, Washington has no state income tax; however, ranks sixth overall, with a 9.51% combined state and local sales tax rate and a 0.75% property tax rate.

How State Taxes Can Influence Retirement Planning

Many investors consider taxes when planning for retirement. Retirees generally have multiple sources of income including Social Security, pensions, investment income, and retirement accounts. The state where someone lives can influence how taxes apply to different sources of income.

While no single tax rate tells the whole story, understanding the combination of a state's income, sales, and property taxes can provide a clearer picture of the tax environment in each state and provide additional knowledge when planning for retirement.

Presidential office denies investigation chief's Cabinet meeting attendance compromises impartiality

The presidential office on Thursday refuted media criticism that the chief of the new investigative body attending Cabinet meetings could compromise impartiality and independence in investigations. The response came amid growing media criticism after Kim Ji-yong, chief of the Serious Crime Investigation Agency (SCIA), attended Tuesday's Cabinet meeting for the first time since taking office, despite the long-held practice of investigation chiefs not attending such meetings. In a social media post the previous day, President Lee Jae Myung said chiefs of all government institutions under his command could attend Cabinet meetings, but many media outlets pointed out that such a move could compromise the investigation chief's independence and impartiality in conducting investigations. "The government is strenuously working toward maintaining fairness and political neutrality in investigations and independence in indictments. This principle will remain unwavering going forward," Lee's senior secretary for the press, Seong Ghi-hong, told reporters. The official also made clear that no individua

Soongsil University, Chung-Ang University team develops technology to disrupt lip-sync deepfakes

A joint research team from Soongsil University and Chung-Ang University has developed a technology to disrupt lip synchronization in deepfake videos that use artificial intelligence (AI) to make a person's lip movements match an audio track. Soongsil University said Tuesday that the team, led by professor Choi Dae-sun of its AI Security Center and professor Kwon Jun-seok of Chung-Ang University, developed the technology, dubbed MUTE. According to the team, MUTE is the first technology to disrupt lip synchronization in deepfake videos using audio protection alone. The paper, titled “MUTE: Multi-Level Alignment Uncoupling Against Talking-Head Exploitation for Voice Protection,” was accepted for presentation at the Conference on Neural Information Processing Systems (NeurIPS) 2026, one of the world’s leading AI conferences. The study was conducted as part of a research and development project supported by the Personal Information Protection Commission and the Korea Internet & Security Agency (KISA). The research team included doctoral student Kim Dong-hyun, master’s student Kim Seung

Seoul claims top spot in global AI adoption, 3rd overall in 2026 AI Cities Index

Seoul has secured third place overall — and claimed the top spot worldwide in artificial intelligence (AI) adoption and implementation — in the newly released 2026 AI Cities Index compiled by Britain’s The Observer, the Seoul Metropolitan Government said Thursday. The benchmark evaluation, built on Tortoise Media’s established Global AI Index, assessed 57 major metropolitan centers across 36 countries using 50 indicators split into three core pillars: investment, innovation and implementation. San Francisco and New York claimed the top two global spots, while Seoul finished third, outranking major international hubs including Beijing, Paris and London, which filled out the fourth through sixth positions. The Observer, founded in 1791 as the world’s oldest Sunday newspaper, introduced city-level rankings for the first time this year, capturing a fundamental shift as AI power increasingly concentrates in urban centers. Seoul’s standout performance came in the implementation category, where it ranked first globally ahead of Tokyo (third) and Singapore (fifth). This metric measu

Hankuk University of Foreign Studies offers training for new hires at semiconductor companies

Hankuk University of Foreign Studies (HUFS) held a two-day training program Oct. 19-20 to help newly hired employees at local semiconductor materials, parts and equipment companies develop practical skills. The university said Wednesday that its G-Anchor Project Group organized the program in cooperation with Yongin City, Gyeonggi Province. The G-Anchor Project is a provincial initiative designed to support universities in promoting regional innovation. Twenty-five newly hired employees from six semiconductor-related companies in Yongin — including Rorze Systems, BMI Tech, GnG InTech, SurplusGlobal, Justem and Appletree — participated in the training. They worked in a range of fields, including manufacturing, design, sales, research and development, and quality control. The training program aimed to deepen participants’ understanding of the semiconductor industry and develop the practical skills and workplace adaptability needed to perform their jobs effectively. Lim Ju-won, a professor in HUFS’ Division of Semiconductor and Electronics Engineering, oversaw the program. Faculty me

Incheon stabbing suspect tests negative for psychopathy

INCHEON — The suspect behind last week's stabbing spree in Incheon has tested negative for psychopathy, police and legal sources said Thursday. The Incheon Metropolitan Police Agency conducted a psychopathy test on the 59-year-old suspect, Choi Choong-rak, but his score fell below the 25 out of 40 points needed to classify him as a psychopath. Choi is accused of attempting to kill 10 people at a commercial complex in Incheon, west of Seoul, on Oct. 13, by wielding knives in both hands. The rampage left eight people injured, including one who remains unconscious after suffering cardiac arrest. The two others escaped without harm. During police questioning, Choi said he carried out the attack out of anger over medical treatment he received at a local hospital. He also told police that he did not target specific people but chose those who looked weaker than him. Choi has 10 prior convictions, including two for attempted murder. Police said they are analyzing evidence and conducting further investigations to determine his motive and whether the attack was premeditated.

Court rules against Lone Star in $125.9-mil. tax case

Court rules against Lone Star in $125.9-mil. tax case

An appeals court on Thursday ruled against U.S. private equity firm Lone Star Funds in its suit against the Korean and Seoul city governments to return a combined 168.2 billion won ($125.9 million) in taxes. The Seoul High Court handed down the ruling against Lone Star after the Supreme Court returned the case to the appeals court for review in April last year. The Texas-based firm had earlier filed the suit against the state and the municipality, seeking the return of withheld taxes in connection with profits from its investments in Korea. Lone Star and affiliate firms purchased large shares of Korea Exchange Bank, Kukdong Engineering Construction and Starlease between 2002 and 2005, and made huge profits by selling some of the shares in 2007. They paid smaller taxes than local companies would have, citing the tax treaty that Korea has with Belgium where the company that made the investment was based. The National Tax Service (NTS) levied additional corporate taxes against Lone Star and its entities, offsetting them with withheld taxes. Lone Star then filed a suit seeking cancellation of

LG Electronics brings AI and robotics to world's largest tidal power plant

LG Electronics is taking its smart factory technology beyond manufacturing and into renewable energy, partnering with Korea Water Resources Corp. to develop artificial intelligence systems for one of the country’s largest power facilities. The companies signed a memorandum of understanding Thursday at Sihwa Lake Tidal Power Plant’s cultural center in Ansan, Gyeonggi Province, to explore AI-driven operations at the facility, which has the world’s largest installed capacity among tidal power plants. The partnership will combine K-water’s power plant operating experience and data with LG Electronics’ expertise in smart factories, digital twins, robotics and AI, the companies said. Under the agreement, they will examine a digital twin-based integrated operating system that creates a virtual model of the plant and incorporates real-time information from generating equipment and surveillance cameras. The system could help forecast electricity output, simulate operating scenarios and diagnose equipment conditions, enabling operators to identify problems and assess performance before m

Orion expands Custard cream cake production in Korea, Vietnam, India as global demand surges

Orion has expanded production lines for its flagship Custard cream cakes across Korea, Vietnam and India to keep pace with surging domestic and international demand, the company said Thursday. Launched in Korea in 2004, Orion Custard is a soft, individually wrapped sponge cake with a custard cream filling. It has become the company’s second-biggest global pie brand after its flagship Choco Pie. Global sales rose 14 percent last year to 154 billion won ($116 million). China, Vietnam and India accounted for 76 percent of that total, and sales kept growing at a double-digit pace through September this year. The company added a production line in Korea in September and recently began running new lines in Vietnam and India. The expansion lifts Custard’s global production capacity to as much as 300 billion won a year, roughly double last year’s sales. Orion’s global research center at its headquarters in Korea oversees product development for each market. In Vietnam, the company sells flavors including tiramisu, raspberry, egg lava, melon and a reduced-sugar version. There is also a fl

Young Poong loses shareholder derivative suit against Korea Zinc

A court on Thursday ruled against Young Poong Corp. in a shareholder derivative lawsuit seeking 837 billion won ($631 million) in damages from Korea Zinc Co. Chairman Choi Yun-beom and other company directors. Young Poong — a major shareholder in Korea Zinc — had filed the suit in November 2024, claiming Korea Zinc's directors had inflicted losses of 837 billion won on the company by making a tender offer involving the purchase of its own shares at 890,000 won apiece, when the actual price was around 560,000 won. The Seoul Central District Court ruled, however, that Korea Zinc's directors could not be deemed to have violated their managerial duties, given the steps they took before making the purchase. It also ruled that the action did not violate the Commercial Act or the company's articles of incorporation.
