Introduction: Expat Tax Ohio Planning for British Families in Columbus and Cincinnati
The expat tax Ohio picture looks simple from a distance and complicated up close. From 2026 the state charges a single flat rate of 2.75%, one of the lowest income tax rates in America. However, Ohio stacks two further income taxes underneath it: a city tax on salaries and business profits, and in many suburbs a school district income tax that can reach UK pensions, UK dividends and UK capital gains. Moreover, Ohio gives no credit for tax paid to HMRC. Consequently, two British families on the same salary can face very different bills depending on which street they choose.
At TaxYork, we prepare federal, state, local and UK returns for British executives, engineers, physicians, investors, company owners and retirees across Columbus, Dublin, New Albany, Upper Arlington, Cincinnati, Indian Hill and Mason. In our experience, newcomers focus on the state rate and overlook the local layers entirely. Therefore this expat tax Ohio guide explains each layer in turn and shows where UK income falls inside or outside it.
Expat Tax Ohio Basics: Four Layers on One Salary
A British family in Ohio can face four income tax layers. First, federal tax reaches worldwide income, relieved by the foreign tax credit on IRS Form 1116. Second, the state taxes residents at 2.75% on income above $26,050. Third, most cities tax wages and business profits, at rates of up to 2.5% in Columbus. Finally, many school districts levy their own income tax. Meanwhile, HMRC keeps taxing UK rent and UK property gains throughout.
Who This Guide Is Written For
This guide addresses high-net-worth British nationals, dual national US UK families and accidental Americans living in Ohio, plus Ohio-domiciled Americans working in London. Specifically, it suits senior executives at the region's manufacturers, insurers, retailers and research employers, as well as investors, business owners and retirees with UK property, pensions, ISAs or company shares. If that describes your household, the expat tax Ohio rules below decide how much of your UK income meets each layer.
How Ohio Compares With Our Other State Guides
Ohio's state rate is low, but the local taxes change the comparison. Missouri now exempts every capital gain, while Illinois charges a flat 4.95% with no foreign credit. By contrast, Hawaii caps gains at 7.25% but credits some UK tax. For the federal rules beneath every state, see our complete 2026 guide to UK expat tax in the USA.
How Ohio Taxes High Earners in 2026
The expat tax Ohio rate schedule finished a three-year cut on 1 January 2026. Therefore the 2026 return is the first that wealthy families file at a genuinely flat rate.
The Expat Tax Ohio Flat Rate
The 2025 budget law, House Bill 96, collapsed Ohio's brackets. For 2025, income from $26,050 to $100,000 was taxed at 2.75% and income above $100,000 at 3.125%, as the Ohio IT 1040 instructions show. From 2026, a single 2.75% rate applies to all nonbusiness income above $26,050. As a result, the expat tax Ohio charge on a large UK pension drawdown or share sale fell by 0.375 points this year.
Exemptions Disappear at High Incomes
Ohio's personal exemption shrinks as income rises and vanishes entirely once modified adjusted gross income reaches $750,000. Similarly, the joint filing credit stops at $750,000. The retirement income credit is capped at $200 per return and is unavailable once income less exemptions reaches $100,000. For a wealthy family, therefore, almost every UK dollar above $26,050 meets the full 2.75% rate.
No Special Rate for Capital Gains
Unlike Hawaii, Ohio gives ordinary investment gains no preferential rate. A gain on UK shares or a London flat is simply part of Ohio adjusted gross income, taxed at 2.75%. Federally, the same gain still bears capital gains tax at up to 20% plus the 3.8% net investment income tax. However, at 2.75% the expat tax Ohio cost of a gain is modest compared with California or New Jersey.
The Business Income Deduction
The expat tax Ohio rules treat business income differently from investment income. Owners of partnerships, S corporations and sole proprietorships deduct the first $250,000 of business income, and pay a flat 3% on business income above that. Furthermore, Ohio's definition of business income includes certain sales of equity or ownership interests in a business. Therefore a founder selling a business they actively ran should test whether the gain qualifies before assuming the ordinary 2.75% treatment applies.
No Credit for UK Tax, but the Exclusion Flows Through
This is where the expat tax Ohio rules most affect British families. Ohio follows the federal starting point closely, so federal choices drive the state result.
The Resident Credit Covers US States Only
Ohio's resident credit, claimed on form IT RC, relieves tax paid to other US states and the District of Columbia. The instructions are explicit: a state means only the 50 US states, and the credit excludes taxes paid to any country, province, territory or city. Consequently, UK income tax on rent, UK tax on a pension paid before an NT code arrives, and non-resident capital gains tax on a London flat all count for nothing in the expat tax Ohio calculation.
Why the Federal Credit Does Not Help
Ohio starts from federal adjusted gross income, while the federal foreign tax credit reduces federal tax after income is calculated. In other words, UK rent that the federal credit shelters completely still arrives on your Ohio return in full. The US-UK tax treaty binds only the federal government, so it cannot close the gap either.
The Foreign Earned Income Exclusion Does Flow Through
By contrast, income excluded under the foreign earned income exclusion never enters federal adjusted gross income, and Ohio does not require you to add it back. For an Ohio-domiciled American working in London, that makes the exclusion worth an extra 2.75% on up to $132,900 of 2026 salary. Our tax treaty optimisation service models the exclusion against the credit across the federal, state and city returns before you elect.
UK Funds and ISAs
The IRS does not recognise the ISA wrapper, so dividends, interest and gains inside an ISA appear on your federal return. Because Ohio follows federal adjusted gross income, the expat tax Ohio charge reaches them too. Similarly, most UK funds are passive foreign investment companies, and the ordinary income they generate under the federal rules flows straight into the Ohio figure.
City Income Taxes in Columbus and Cincinnati
For expat tax Ohio purposes, the cities tax income independently of the state. The expat tax Ohio bill for a city resident or city worker therefore includes a second return with its own rules.
Rates and the Resident Credit
Columbus charges 2.5% on residents and on non-residents who work in the city. The City of Columbus Income Tax Division explains that residents receive a 100% credit for tax paid to another city, up to 2.5%. Cincinnati charges 1.8% and gives residents a credit for other cities' tax up to its own rate. As a result, a resident pays roughly the higher of the two cities' rates, not both.
What the City Taxes, and What It Leaves Alone
City taxes fall on salaries, wages, bonuses and the net profits of businesses, including rental activity. Columbus states that pension income, Social Security, interest and dividends are not subject to city tax, and Ohio's municipal rules generally exclude capital gains as intangible income. Therefore a retired British couple living on UK pensions and investment income usually owes the city little or nothing. However, Columbus treats leasing property you own as a taxable business activity, so we review a UK buy-to-let carefully before deciding how to report it.
Residents Working in London
A city taxes its residents on wages wherever they are earned. Consequently, an American who keeps a Columbus home while seconded to London can face city tax on the London salary, with no credit for UK tax. The federal exclusion does not bind the city either. In practice, therefore, we plan the housing and residency position before a secondment starts, because unwinding it afterwards is far harder.
School District Income Taxes: The Layer That Reaches UK Pensions
This is the least understood part of every expat tax Ohio review we carry out. School district income taxes are voted locally, so two neighbouring suburbs can differ completely.
Traditional Base Versus Earned Income Base
Each taxing district uses one of two bases, and the choice transforms the expat tax Ohio result. The Department of Taxation's guide to school district income tax explains that a traditional base starts from Ohio adjusted gross income and taxes interest, dividends, pensions, annuities and capital gains. Furthermore, it adds back the business income deduction. An earned income base, by contrast, taxes only wages and self-employment earnings. Consequently, a UK pension or a London flat sale escapes an earned income district entirely, yet meets the full rate in a traditional district.
Rates in the Suburbs Britons Choose
The state's 2025 rate table shows how much location matters. Bexley, an inner Columbus suburb, levies 0.75% on the traditional base, and Granville levies the same. Pickerington charges 1% on the traditional base. Near Cincinnati, Wyoming charges 1.25%, also on the traditional base. Meanwhile, Upper Arlington, New Albany-Plain, Dublin, Indian Hill, Mason and Sycamore showed no school district income tax in the 2025 table. Therefore check the district, not the postal town, before you sign a lease or buy.
Why the School Tax Hits British Retirees Hardest
City taxes ignore pensions and investment income, but a traditional school district tax does not. As a result, a British retiree drawing a large SIPP income and selling UK shares can pay more school district tax than city tax. In addition, there is no credit for UK tax against it. For the expat tax Ohio planning of a retiring couple, the school district choice can matter more than the state rate.
UK Pensions, Rent and Gains in Ohio
Every expat tax Ohio review works through the family's UK income one item at a time. Each item meets a different combination of layers.
SIPP and Workplace Pension Drawdowns
Under Article 17 of the treaty, a UK pension paid to a US resident is usually taxable only in the United States, so HMRC can issue an NT code and pay you gross. Federally, the drawdown is taxed under the IRS rules on foreign pension distributions, and the state adds 2.75%. Furthermore, the 25% lump sum that is tax-free in Britain is taxable for a US resident, because the treaty's saving clause preserves US tax. City tax does not apply, but a traditional school district tax does.
The UK State Pension Is Not Social Security
Ohio deducts US Social Security benefits in full. However, the UK State Pension is not US Social Security, and the IRS treats it as fully taxable pension income. Consequently, the Ohio deduction does not reach it, and your UK State Pension meets the expat tax Ohio rate of 2.75%, plus any traditional school district tax.
UK Rental Income
Britain keeps first right to tax UK rent, and HMRC explains the rules for UK rental income when you live abroad. Federally, the UK tax is credited against US tax on the same rent. The expat tax Ohio charge, however, hits the full net rent again at 2.75% with no credit. Moreover, US depreciation usually produces a different net figure from the UK computation, so the two returns rarely match.
Selling UK Shares or Property
HMRC does not usually tax non-residents on UK shares, so a share sale meets only federal tax, the state's 2.75% and any traditional school district tax. However, if you left Britain recently and return within five full years, HMRC can tax gains on assets you owned when you left, under the statutory residence test guidance. A London flat is different again, because HMRC charges non-residents on UK property gains, and the expat tax Ohio calculation gives no credit for that tax.
Ohio Residency and Domicile
Ohio residency decides who pays expat tax Ohio on worldwide income. The rules matter for Britons arriving and for Ohio Americans leaving for London.
Domicile and the Abode Presumption
Under the expat tax Ohio rules, resident and domiciled mean the same thing. Furthermore, anyone with an abode in Ohio, owned or rented, is presumed to be a resident, and a temporary absence does not change that. Federally, a British national usually becomes a resident alien under the substantial presence test from the first day of presence. Therefore your federal and Ohio start dates can differ in the arrival year, and the part-year return must reflect both.
The Contact Period Test
Ohio counts contact periods rather than days. You have a contact period when you are in Ohio on two consecutive days while away overnight from an abode elsewhere. If you have fewer than 213 contact periods, you must show it is more likely than not that you were a nonresident. With 213 or more, the standard rises to clear and convincing evidence.
The Nonresident Statement for Americans in London
An Ohio American posted to London can establish an irrebuttable presumption of nonresidency by ticking the Ohio nonresident statement box on the return. To qualify, you need no more than 212 contact periods, an abode outside Ohio, no Ohio driver's licence or ID card, no homestead or owner-occupied property tax reduction and no in-state tuition. Importantly, the licence must be surrendered before the tax year begins. Consequently, a missed step in December can cost a full year of expat tax Ohio on a London salary.
Case Study: The Pembertons in German Village
This illustrative case study shows how the expat tax Ohio layers combine for a real-world family. The names are invented and the figures are simplified, but the pattern matches what we see every season.
The Facts
David Pemberton is a British executive who moved to German Village, inside the City of Columbus, in 2024 with his wife Sarah. In 2026 David earns $600,000 of salary at a downtown Columbus office. Sarah draws £50,000 from a UK workplace pension, and the couple own a Bristol flat producing £30,000 of net rent. In addition, David sells a UK share portfolio for a gain of £300,000, and their ISAs pay £8,000 of dividends. At an illustrative $1.32 to the pound, the pension is $66,000, the gain $396,000 and the ISA income $10,560. After US depreciation, the net rent is $33,600.
The State Bill
Their Ohio adjusted gross income is $1,106,160. Because it exceeds $750,000, they receive no personal exemptions. Their expat tax Ohio charge is therefore 2.75% of the income above $26,050, which is about $29,700. Of that sum, roughly $13,900 relates to UK income, and Ohio gives no credit for the £3,486 of UK tax on the rent. Had the gain fallen in 2025, the 3.125% band would have added nearly $1,500 more.
The City and School District Bills
Columbus withholds 2.5% on David's salary, which is $15,000. On our reading, the city also reaches the net profit of the Bristol flat, adding about $840, while the pension, the gain and the ISA dividends escape city tax. Columbus City Schools levy no income tax. However, had the family bought in Bexley instead, the 0.75% traditional school district tax would have added about $8,300, mostly on UK income. In Wyoming, near Cincinnati, the 1.25% rate would have cost about $13,800.
The Federal Position and the Lesson
Federally, the share gain pays 20% plus the 3.8% net investment income tax, which is $94,248, and HMRC charges nothing because they are non-resident. You can model that element with our US capital gains tax calculator. In Hawaii the same gain would have cost $28,710 in state tax, against $10,890 here. Therefore the lesson is twofold: Ohio's state rate is light, but the school district decides whether UK pensions and gains meet a second charge.
Compliance That Comes With Ohio Residency
Living in Ohio adds state, city and school district filings to an already heavy federal and UK load. The expat tax Ohio calendar is manageable, but each layer has its own return.
Deadlines and Extensions
Ohio IT 1040 and school district SD 100 returns are due on 15 April. Ohio has no extension form of its own, but it honours a federal extension, moving the filing date to 15 October. However, an extension never extends the time to pay, and interest runs from 15 April. City returns follow their own rules, and Columbus expects quarterly estimates from residents without full withholding.
FBAR and Form 8938
Ohio has no foreign account report of its own. However, as a US tax resident you must file an FBAR through FinCEN's BSA E-Filing system if your UK accounts, including ISAs and many pensions, exceed $10,000 combined at any time in the year. Married couples living in Ohio must also file Form 8938 once foreign assets pass $100,000 at year end or $150,000 at any time. Our FBAR and FATCA reporting service covers both.
Missed Ohio, City and School District Returns
Missed school district returns are common, because many newcomers never realise their district levies a tax. Similarly, missed city returns arise when an employer withholds for the work city but not the home city. These facts usually sit alongside missed US tax returns and a missed FBAR. Therefore we prepare the outstanding federal, state, city, school district and UK filings together, so the figures agree and the exposure closes in one exercise.
How TaxYork Can Help
TaxYork provides comprehensive US tax return preparation for expats and US UK tax returns preparation for families who live across both countries. We handle every expat tax Ohio layer as part of one joined-up compliance process.
Joined-Up Returns
We prepare your federal return, Ohio IT 1040, SD 100, city returns and UK self assessment together, using the same exchange rates and dates throughout. As a result, the foreign tax credit, the business income deduction, the school district base and HMRC's figures reconcile. Nothing is taxed twice by accident, and no exemption is left unclaimed.
Before the Move, the Purchase or the Sale
The largest savings come before you choose a house, sell an asset or start a secondment. Therefore our cross-border planning and compliance team reviews school districts, pension drawdowns, share sales and residency steps while there is still time to change the outcome.
Conclusion
Ohio's 2.75% flat rate makes it one of the lighter income-tax states for a British family, and its municipal taxes leave pensions and investment income alone. However, the state gives no credit for UK tax, the cities tax salaries and rental profits, and traditional school district taxes reach UK pensions, dividends and gains. Moreover, Ohio Americans in London must follow the nonresident statement rules precisely. In short, the expat tax Ohio bill rewards families who choose their school district carefully and plan their UK income around every layer.
