Introduction: Expat Tax Arkansas Planning for British Families
The expat tax Arkansas position looks simple at first glance. From 1 January 2026 the top rate fell to 3.7%, half of every long-term capital gain is ignored, and gains above $10 million are not taxed at all. However, Arkansas gives no credit for income tax paid to the United Kingdom. Instead, it offers a little-known itemised deduction for foreign income tax, which most software never prompts for. Consequently, a British family in Bentonville, Rogers, Fayetteville or Little Rock needs far more than a rate table.
This guide is written for senior executives, founders, investors and their families who have moved from London to north-west Arkansas or to the state capital. It explains how the expat tax Arkansas rules interact with your federal return, your UK tax position and the foreign account reporting that catches so many newcomers. Throughout, we use the current 2026 figures and a worked case study with real numbers.
Expat Tax Arkansas Basics: Three Returns, Not Two
Most British arrivals expect two tax systems: the IRS and HMRC. In practice, you face three. First, once you hold a green card or pass the IRS substantial presence test, the federal government taxes your worldwide income. Second, Arkansas taxes the same worldwide income because you are domiciled in the state. Third, HMRC continues to tax UK rent, UK-source employment income and, in some cases, UK pensions. The expat tax Arkansas question is therefore about how these three layers fit together, and where relief is missing.
Who This Guide Is Written For
We wrote this for high-net-worth readers with genuinely cross-border affairs. Typically, that means a British executive seconded to a retail, logistics or consumer-goods headquarters in Benton County, a dual national US UK couple returning from London with a portfolio of UK investments, or a founder who has sold, or plans to sell, a UK company after moving. If your income includes restricted stock units, a UK final salary pension, UK rental property or ISAs, the detail below applies directly to you.
How Arkansas Compares With Our Other Southern State Guides
Arkansas sits between its neighbours. Texas and Tennessee levy no wage tax at all, as our guides to British expats in Texas and British expats in Nashville explain. Missouri and Oklahoma, by contrast, run graduated income taxes with their own quirks, which we cover in our Missouri guide for British expats and our Oklahoma guide for British expats. Arkansas is unusual because it builds its own definition of income rather than starting from federal adjusted gross income. As a result, several federal items behave differently on the state return.
Arkansas Income Tax Rates for 2026 and the Year of Arrival
Arkansas has cut its individual rate repeatedly since 2022. In May 2026, legislation from the first extraordinary session reduced the top rate from 3.9% to 3.7%, with effect from 1 January 2026. Therefore, the expat tax Arkansas bill for 2026 is lower than for 2025, and the year you arrived matters.
Expat Tax Arkansas Rate Tables for 2026
For taxable income up to $94,700, the 2026 table runs from 0% on the first $5,599, through 2%, 3% and 3.4%, to 3.7% on income between $26,400 and $94,700. Above $94,700, a separate high-income table applies. It charges 2% on the first $4,700 and 3.7% on everything above that. In effect, a high earner pays 3.7% of taxable income less roughly $80. A small bracket adjustment smooths the step between $94,701 and $97,600. Because the tables are indexed for inflation, the final figures the state publishes may move by a few dollars.
The 2025 Expat Tax Arkansas Table for Earlier Arrivals
If you arrived in 2025, your first return uses the 2025 indexed table, where the top rate was still 3.9%. The structure is the same: a low-income table up to $94,700 and a high-income table above it. Consequently, a family with $800,000 of Arkansas taxable income pays roughly $1,600 more for 2025 than it would for the same income in 2026.
Standard Deduction and Personal Credits
Under the expat tax Arkansas rules, the standard deduction is tiny. For 2025 it was $2,470 for a single filer and $4,940 for a married couple filing jointly. Instead of personal exemptions, Arkansas gives a personal tax credit of $29 per taxpayer, with extra credits for those aged 65 or over. For a wealthy household, these amounts are trivial. However, the low standard deduction has one important consequence: almost every high earner should itemise, and itemising is what unlocks the foreign tax deduction described below.
No Credit for UK Tax: The Foreign Tax Deduction Instead
This is the single most important expat tax Arkansas point, and the one competitor guides miss entirely. Arkansas does not give a credit for income tax paid to a foreign country. Instead, it allows that tax as an itemised deduction.
The Other State Tax Credit Covers States Only
For expat tax Arkansas purposes, residents can claim a credit on Form AR1000TC for income tax paid to another US state. The state's own instructions say the purpose is to stop residents "being taxed twice on income earned outside of the state of Arkansas". However, the credit is limited to other states and territories. UK income tax does not qualify, and neither does UK National Insurance. Consequently, income that HMRC taxes in full is still fully taxable in Arkansas.
Form AR3: Foreign Income Tax as an Itemised Deduction
Arkansas Form AR3, the itemised deduction schedule, lists the taxes you may deduct. Alongside city income taxes and personal property taxes, the 2025 instructions include "taxes paid to a foreign country on income taxed on this return". In other words, UK income tax on income that also appears on your Arkansas return is deductible. At a 3.7% rate, every $10,000 of UK tax saves $370 on your expat tax Arkansas bill. That is far less than a full credit would give, but for a family paying $50,000 or more to HMRC it is a meaningful sum.
Why the Federal Credit Does Not Block the State Deduction
Federally, you choose each year between a credit and a deduction for foreign tax, and nearly every high earner takes the credit on IRS Form 1116. Arkansas, however, writes its own deduction rules. The AR3 instructions contain no requirement that you forgo the federal credit before deducting the same UK tax on the state return. Therefore, the usual position is that you claim the federal credit and the Arkansas deduction for the same pounds. We see many expat tax Arkansas returns where this deduction is simply missing, because the software carries federal itemised deductions across and the federal return shows no foreign tax deduction.
What the Deduction Does Not Cover
The deduction covers foreign tax "on income taxed on this return". So UK tax on income that Arkansas does not tax is not deductible. For example, if an Arkansas-domiciled American working in London claims the foreign earned income exclusion on the state return, the UK tax on that excluded salary cannot also be deducted. Similarly, UK National Insurance is a social security contribution, and US-UK totalisation rules usually decide which country collects it, so it does not belong on Form AR3.
How Arkansas Taxes Your UK Income
Because Arkansas builds its own income figure, each type of UK income needs separate attention. Here is how the expat tax Arkansas rules treat the items we see most often.
UK Workplace Pensions and the $6,000 Exemption
Arkansas exempts the first $6,000 a year of income from an "employer-sponsored retirement plan", including disability retirement. The instructions do not limit this to American plans. Therefore, a reasonable reading is that a UK final salary scheme or an employer's defined contribution scheme qualifies, because both are sponsored by an employer. Each spouse can claim a separate $6,000 against their own pension, but a surviving spouse is limited to a single exemption. Above $6,000, the pension is fully taxable at expat tax Arkansas rates. Under Article 17 of the US-UK double taxation convention, a UK private pension paid to a US resident is generally taxable only in the United States, so you should ask HMRC for a no-tax code to stop UK deductions at source.
SIPPs, Drawdown and the Tax-Free Lump Sum
A self-invested personal pension is not employer-sponsored, so we treat it with more caution. Drawdown income from a SIPP is likely to be fully taxable in Arkansas without the $6,000 exemption, unless the funds came from an earlier employer scheme. Moreover, the UK's 25% tax-free lump sum is not tax-free in America. The treaty's protection for lump sums does not override the federal saving clause, so the IRS taxes it, and Arkansas follows because the payment is income on the state return. Planning the timing of a lump sum around your move is therefore worth far more to your expat tax Arkansas position than the exemption.
The UK State Pension
Arkansas exempts US Social Security benefits completely. However, the UK State Pension is not US Social Security. The exemption in the instructions names Social Security, VA benefits, workers' compensation and railroad retirement benefits, and the UK State Pension is none of these. Furthermore, because it is a state benefit rather than an employer plan, the $6,000 exemption does not obviously apply either. Consequently, we treat the UK State Pension as fully taxable under the expat tax Arkansas rules. Federally, Article 17(3) of the treaty makes it taxable only in the United States, and the GOV.UK guidance on claiming the State Pension abroad confirms that it is paid gross to US residents.
UK Rent, ISAs and UK Funds
UK rental profit is taxable in the UK and also on your expat tax Arkansas return. Fortunately, the UK tax on that rent is deductible on Form AR3. ISAs receive no recognition in America, so ISA interest, dividends and gains appear on your federal and Arkansas returns. UK collective funds and OEICs held inside or outside an ISA are usually passive foreign investment companies, which require IRS Form 8621 each year. That federal regime creates its own expensive tax charges, and Arkansas generally follows the income figures that result.
Capital Gains: The 50% Exclusion and the $10 Million Cap
For founders and investors, this is where the expat tax Arkansas position becomes genuinely attractive. Arkansas taxes only half of net long-term capital gains. Short-term gains, on assets held for a year or less, are taxed in full.
How Form AR1000D Works
On Form AR1000D, you net your long-term and short-term gains and losses. Then, if the Arkansas net long-term gain exceeds $10 million, you enter only $10 million. Finally, you multiply that figure by 50%. The excess over $10 million therefore escapes Arkansas tax entirely. In practice, the most the expat tax Arkansas rules can charge on a single year's long-term gains is about $185,000, which is $10 million multiplied by 50% and by 3.7%.
Selling a UK Company After Moving
Suppose a founder moves to Bentonville and then sells shares in a UK trading company. Federally, the gain is taxable at 20% plus 3.8% net investment income tax. In the UK, a non-resident is generally outside capital gains tax on shares, although the five-year temporary non-residence rules can pull the gain back if you return to Britain too soon. Meanwhile, Arkansas taxes half the gain, capped at $10 million. On a $30 million gain, the Arkansas charge is roughly $185,000, an effective rate of about 0.6%. However, the order of events matters. If the sale completes before you become domiciled in Arkansas, the gain falls into a part-year period when you were not resident, and Arkansas has no claim at all.
Investment Portfolios and Holding Periods
For a typical portfolio, the 50% exclusion cuts the effective state rate on long-term gains to about 1.85%. However, short-term trading gains, UK fund distributions taxed as ordinary income and PFIC excess distributions do not receive the exclusion. Therefore, holding periods and fund structure matter for your expat tax Arkansas bill as well as your federal one.
Equity Pay, Bonuses and the Year of the Move
Many British arrivals in north-west Arkansas are executives with restricted stock units or performance shares granted while they worked in London. This creates the most common double-tax problem we see.
RSUs Earned Partly in the UK
HMRC taxes an internationally mobile employee's equity on a workday basis. If an award vests after you move but 40% of the vesting period was spent working in the UK, then HMRC taxes 40% of the vesting value at up to 45%. Federally, you can credit that UK tax against US tax on the same foreign-source slice. The expat tax Arkansas rules, however, tax the whole vesting value because you are resident when it vests, and gives no credit for the UK tax. The only relief is the foreign tax deduction on Form AR3.
Bonuses Paid After Arrival
A bonus for work performed in London but paid after you become an Arkansas resident follows the same pattern. HMRC taxes it as UK employment income. Arkansas taxes it because you received it while resident. Consequently, the expat tax Arkansas cost of a deferred bonus is roughly 3.7% of the gross amount, less 3.7% of the UK tax deducted. Where you can influence timing, receiving the bonus before your move can remove the Arkansas layer altogether.
Part-Year Residents in the Year of the Move
In the year you arrive, you file Form AR1000NR as a part-year resident. You report all income received while an Arkansas resident, plus any Arkansas-source income from before. Arkansas then apportions the tax by the share of your total income that belongs to Arkansas. Therefore, careful records of what you received before and after the date your domicile changed are essential to an accurate expat tax Arkansas return.
Residency, Domicile and the London Trap
Arkansas defines residence by domicile, meaning the place you intend to have as your permanent home. This rule cuts both ways, and it is a frequent expat tax Arkansas surprise.
When a British National Becomes Resident
A British executive who moves to Bentonville with their family, buys or rents a home and enrols children in local schools will usually be treated as domiciled from arrival. A short project assignment with a clear end date may not change domicile, which can keep you outside the expat tax Arkansas net. However, the burden is on you to show that your stay is temporary, and moving your whole household rarely supports that argument.
Arkansas-Domiciled Americans Working in London
The state's instructions say that if you move somewhere intending to stay only "for a limited time (no matter how long), your domicile does not change", and that "this also applies if you are working in a foreign country". So an American from Little Rock on a three-year London secondment usually remains a full-year Arkansas resident. They must file Form AR1000F and report worldwide income, including London salary taxed by HMRC. Arkansas's electronic filing rules expect federal Form 2555 to be attached wherever the foreign earned income exclusion is claimed. Even so, the UK tax on any excluded salary is not deductible, as we explained above. Formally changing domicile before a long posting can therefore save a great deal of tax under the expat tax Arkansas rules.
Leaving the UK: The Statutory Residence Test
On the UK side, HMRC applies the statutory residence test set out in HMRC guidance note RDR3. If you leave to work full time abroad, split-year treatment can make you non-resident from the day you leave. After that, the UK taxes only UK-source income such as rent, UK duties and UK workday equity, as the GOV.UK page on tax on foreign income and residence explains. The GOV.UK guide to tax if you leave the UK to live abroad sets out the forms you need to file.
Property Tax, Sales Tax and Local Costs
The expat tax Arkansas picture includes no local income taxes, unlike Ohio or Alabama. However, other local taxes matter to a wealthy household.
Property Tax and the Homestead Credit
Arkansas property tax is low by national standards. Homeowners can claim a homestead credit against the tax on their principal residence, and owners aged 65 or over, or disabled, can freeze the assessed value of their home. However, a second home in the Ozarks receives neither benefit. Property tax on your home is deductible on Form AR3, which helps you clear the small standard deduction.
Sales Tax Is High
The state sales tax rate is 6.5%, and city and county levies add more. Consequently, combined rates in many Arkansas towns are among the highest in the country. For a family furnishing a new home and buying vehicles, this cost often exceeds the expat tax Arkansas saving compared with a higher-tax state.
Foreign Account Reporting and Catching Up
The expat tax Arkansas return is only one part of your compliance. Your federal return carries the foreign account reporting that generates the largest penalties.
FBAR and Form 8938
If the combined value of your non-US accounts exceeds $10,000 at any point in the year, you must file an FBAR through the FinCEN BSA e-filing system. The IRS page on the Report of Foreign Bank and Financial Accounts sets out who must file. In addition, married couples living in the United States must file Form 8938 once specified foreign assets exceed $100,000 at year end or $150,000 at any time. The IRS summary of FATCA reporting compares the two regimes. UK current accounts, ISAs, workplace pensions and SIPPs all count.
Why Gaps Are Common Among New Arrivals
British nationals often do not realise that a green card makes them US tax residents for every purpose, including foreign account reporting. Moreover, an accidental American spouse, born in America but raised in Britain, may never have filed at all. As a result, missed FBARs and missing Forms 8621 are common among the expat tax Arkansas clients who have just arrived.
Putting Missed Years Right
If you have missed returns or FBARs, the route depends on your facts. The IRS Streamlined Filing Compliance Procedures remain available to non-wilful taxpayers, and our IRS Streamlined filing service explains how the domestic and foreign versions differ. Once you live in Arkansas, the domestic version usually applies, with a 5% penalty on the highest year-end balance of the unreported assets. The expat tax Arkansas regime has no formal amnesty for these years, so state returns for any missed year are usually filed alongside the federal catch-up.
The IRS Guidance for Americans Abroad
The IRS also publishes general guidance for US citizens and resident aliens abroad, which is useful for any family member still living in Britain. Our FBAR and FATCA reporting service handles the account schedules, the Form 8938 valuations and the PFIC calculations as one piece of work.
Case Study: A Retail Executive's Family in Bentonville
To show how the expat tax Arkansas rules fit together, here is an illustrative case based on the kinds of families we work with. The figures are rounded and use an exchange rate of $1.35 to the pound.
The Income
James, a British national, moved from London to Bentonville in December 2025 with his wife Sarah, a dual national US UK who had lived in Britain since childhood. James holds a green card, and they file jointly. In 2026, James earns a salary of $420,000. RSUs worth $300,000 vest in March, and 40% of the vesting period relates to his UK workdays. They also receive £30,000 of rent from their London flat, which is $40,500, and Sarah draws £20,000, or $27,000, from a former employer's UK final salary scheme. Finally, they sell a long-held US share portfolio for a $200,000 long-term gain.
The UK Tax
HMRC taxes the UK-workday slice of the RSUs, which is $120,000, at 45%, so the UK tax is $54,000. The London rent produces UK tax of about £3,486, or $4,706, after James's personal allowance. Sarah's pension is taxable only in the United States under the treaty, so she obtains a no-tax code and HMRC deducts nothing. In total, the family pays $58,706 of UK income tax.
The Arkansas Bill
Arkansas income is the salary of $420,000, the full RSU value of $300,000, rent of $40,500, Sarah's pension of $21,000 after the $6,000 exemption, and half of the $200,000 gain, which is $100,000. That totals $881,500 of expat tax Arkansas income. Without the foreign tax deduction, their itemised property tax and mortgage interest of $24,000 leaves taxable income of $857,500, and the 2026 tax is about $31,590 after personal credits. However, adding the $58,706 of UK tax on Form AR3 reduces taxable income to $798,794. The tax falls to about $29,417, which is a saving of $2,173 every year the UK tax continues.
The Federal Side and What Changes the Answer
Federally, James claims a foreign tax credit for the UK tax on the RSUs and the rent. On the RSU slice, US tax at 37% is about $44,400, so roughly $9,600 of UK tax is excess and carries forward for up to ten years. Sarah had never filed FBARs for her UK accounts, so the family also files missed FBARs under the domestic Streamlined route. If James had arranged for his March vesting to happen before the move, Arkansas would have had no claim to the $300,000, which would have saved about $11,100 of state tax. Similarly, if they ever sell a business for more than $10 million, the cap means the extra gain carries no Arkansas tax at all.
How TaxYork Can Help
At TaxYork, we prepare federal, state and UK returns for British and American families as one coordinated file. That is especially valuable for expat tax Arkansas clients, where the state ignores federal adjusted gross income and the foreign tax deduction is so often missed.
Expat Tax Arkansas Returns Prepared as One File
Our US tax returns for expats service covers Form 1040, Forms 1116, 2555, 8621 and 8938, and the Arkansas AR1000F or AR1000NR with Forms AR3, AR1000D and AR1000TC. Moreover, we prepare the UK Self Assessment return for your London rent and UK workday income in the same engagement. Consequently, the figures match across all three returns, and every expat tax Arkansas relief is claimed in the right order.
Executives, Founders and Property Owners
For equity-heavy executives, we model the timing of vesting and bonuses around the move. For founders, we plan sales around the $10 million cap and the UK temporary non-residence rules. Our tax treaty optimisation service covers pension positions, no-tax codes and the foreign tax credit, while our cross-border planning service deals with the order of events before a move.
Conclusion
The expat tax Arkansas rules reward careful preparation. The headline 3.7% rate and the generous capital gains treatment are attractive. However, the absence of any credit for UK tax means that RSUs, bonuses and UK rent are taxed twice at state level, with only a partial deduction as relief. In addition, Arkansas's domicile rule keeps Americans posted to London inside the state's tax net. Therefore, the families who do best with expat tax Arkansas are those who plan the order of events before they move, claim the Form AR3 deduction every year, and keep their FBAR and Form 8938 reporting complete from the first year.
