Americans in Scotland Tax: The Move Year, the S Code and Your US Return

Americans in Scotland tax: an introduction

Americans in Scotland tax questions peak in the year you move. One statutory test then decides your income tax rates for the whole UK tax year. If Scotland wins that test, Scottish rates apply from 6 April, even if you arrived in February. Your US return then has to absorb a different UK tax figure, often a higher one.

This article supports our guide to US and UK tax returns. It is for US citizens and green card holders moving into Scotland, out of it, or between Scotland and England. We cover the Scottish taxpayer test, the S code and the 2026 to 2027 rates. Then we turn to your US foreign tax credit and to buying a home.

Why Americans in Scotland tax returns start with one test

A Scottish taxpayer is a UK resident whose closest connection, for that tax year, is with Scotland. HMRC's Scottish taxpayer technical guidance is clear that this status covers a whole tax year. You cannot be a Scottish taxpayer for part of a year. Therefore, the date you move matters far more than most people expect.

What this article leaves out

We do not cover North Sea offshore work, Scottish inheritance planning or Scottish company matters. Likewise, we only touch on US state tax in passing. Our article on state tax after moving to the UK deals with leaving your old state.

Who counts as a Scottish taxpayer in the year you move?

You are a Scottish taxpayer if you are UK resident and your main home was mostly in Scotland. Specifically, it must sit there for more of the tax year than in any other part of the UK. If no main home can be identified, a day count decides.

Step one: are you UK resident at all?

Residence comes first. HMRC states that someone who is not UK tax resident cannot be a Scottish taxpayer. The statutory residence test decides UK residence, and HMRC explains it in guidance note RDR3. In your arrival year, split year treatment may also divide the year into non-resident and resident parts.

Step two: the close connection test

The rule is in section 80D of the Scotland Act 1998, with the close connection test in section 80E. Say your only UK home is in Scotland and you live there for part of the year. Then you have a close connection with Scotland. With two or more homes, the statute compares where your main home was. Scotland must cover more of the year than England, Wales or Northern Ireland, each taken separately. HMRC's manual words it as at least as much of the year, so a near-even split is contested. In that case, the cautious approach is to plan on the statute's stricter wording.

Step three: the day count fallback

Sometimes no main home can be found, for example when you rotate between short lets. In that case, HMRC's manual at STTG4500 applies a day count. You need more days in Scotland than in any other part of the UK. A day counts where you are at midnight, and days spent only in transit do not count.

What happens when you move between Scotland and England?

The part of the UK that held your main home for longer wins the whole year. There is no split year for a move within the UK. Instead, the tax code is corrected back to 6 April.

The whole-year swing

HMRC's own example at STTG4400 shows a man renting in Birmingham, then moving into an Aberdeen flat on 30 June. Aberdeen covers the longer period, so he is a Scottish taxpayer for the whole year. Reverse the order, and he is not. Consequently, two moves on the same date can give opposite answers. Americans in Scotland tax planning for a move should start with that date.

What the S code means

A tax code is the instruction HMRC gives your employer or pension provider. GOV.UK explains what your tax code means. An S at the front means your pay or pension is taxed at Scottish rates. A C means Welsh rates. So a code of S1257L gives the standard allowance, taxed in Scottish bands.

Tell HMRC, or face a catch-up

GOV.UK's page on moving to or from Scotland says you must give HMRC your new address. When HMRC changes your rate, the new rate is backdated to 6 April of the year you moved. Your payroll then adjusts automatically. In practice, a late update can mean a sharp drop in take-home pay in the final months of the year.

What are the Scottish income tax rates for 2026 to 2027?

Scotland has six bands for 2026 to 2027, from a 19% starter rate to a 48% top rate. Scottish rates cover wages, pensions and most other income, but not savings interest or dividends.

The six bands

The bands below come from GOV.UK's Scottish Income Tax page and the Scottish Government's rates and bands. They assume the standard £12,570 personal allowance. The starter rate of 19% runs from £12,571 to £16,537. Next, the basic rate of 20% runs to £29,526, and the intermediate rate of 21% runs to £43,662. The higher rate of 42% then runs to £75,000. Above that, the advanced rate of 45% applies up to £125,140, and the top rate of 48% applies beyond it.

How that compares with England

For the rest of the UK, GOV.UK's income tax rates show 20% up to £50,270. Then 40% applies up to £125,140. Above that, the rate is 45%. As a result, a Scottish salary above about £33,500 bears more income tax than the same salary in England. In both systems, the personal allowance falls by £1 for every £2 of income over £100,000.

Savings and dividends stay on UK rates

GOV.UK states that dividends and savings interest are taxed at the same rates as the rest of the UK. For 2026 to 2027, GOV.UK's dividend page lists a £500 allowance and rates of 10.75%, 35.75% and 39.35%. So the Scottish bands only reach your pay, pension and similar income, a detail many Americans in Scotland tax estimates miss. Your US return ignores this split and applies its own rules to every type of income.

How does a higher Scottish rate change your US foreign tax credit?

Usually, it does not cut your US tax further. The credit is already capped at the US tax on your UK income. Instead, the extra Scottish tax mostly becomes excess credit that you carry to other years.

The credit limit

The foreign tax credit is a dollar-for-dollar credit against US tax for income tax paid to another country. However, it is limited to the share of your US tax on foreign income. You work this out by category on Form 1116. Scottish income tax is UK income tax charged at Scottish rates and collected by HMRC. So the Americans in Scotland tax credit works as it does elsewhere in the UK. Our article on Form 1116 and UK tax sets out the calculation in detail.

Carrying the excess

The IRS page on how to figure the credit covers unused foreign tax. It may be carried back to the previous tax year and forward to the next 10 years. In a year you arrive from the US, the year before usually had no UK income. Therefore, the carryback rarely helps, and the carryforward is the figure to track.

When the carryover pays off

Excess credit is only worth something when a later year has room in the same category. That is why Americans in Scotland tax returns should carry the schedule forward every year. For instance, you might later move to a lower-tax country. Alternatively, you might return to the US but keep some UK-source pay. IRS Publication 514 explains the separate categories and the carryover rules. Accordingly, we keep a year-by-year schedule of carryovers by category on every Americans in Scotland tax file.

What does a move year look like in figures?

Here is one move from London to Edinburgh, priced both ways. The Scottish result raises UK tax by about £1,950 and adds the same amount, in dollars, to the excess credit.

Consider a typical case

Kelsey is a fictional US citizen who has lived in London since 2024. She earns a salary of £70,000, with no other income. On 1 August 2026 she moves into a flat in Edinburgh, and gives up her London rental. In the 2026 to 2027 tax year, her main home was in London for 117 days. It was in Edinburgh for 248 days. Edinburgh covers more of the year, so Kelsey is a Scottish taxpayer for the whole year. In our experience, this pattern sits behind most Americans in Scotland tax questions.

The UK figures

At Scottish rates, her income tax for 2026 to 2027 is about £17,382. At the rates for England, it would be £15,432. The difference is about £1,950. Meanwhile, her payroll used English rates until August. The S code then recovers that shortfall over the remaining months.

The US figures

For simplicity, we assume $1.32 to the pound and treat the UK year as matching her US year. Her pay is then $92,400, and her UK tax is about $22,944. We assume her US tax before credits is $11,500. The credit wipes out that $11,500 either way, so Kelsey owes no US income tax. However, her excess credit rises from about $8,870 at English rates to about $11,444 at Scottish rates. On a real return, you convert consistently, for example with the IRS yearly average rates.

What should you check when buying a home in Scotland?

You pay Land and Buildings Transaction Tax, not stamp duty. Moreover, a home you still own in America can trigger the 8% Additional Dwelling Supplement. Neither tax is deductible on your US return.

LBTT bands

Land and Buildings Transaction Tax, or LBTT, is Scotland's tax on buying land and property. It is often the largest one-off cost in Americans in Scotland tax files. Revenue Scotland's residential rates are 0% up to £145,000, then 2% to £250,000 and 5% to £325,000. After that, the rate is 10% to £750,000 and 12% above. First-time buyer relief lifts the nil rate band to £175,000.

The supplement and your US house

The Additional Dwelling Supplement is 8% of the whole price for contracts made on or after 5 December 2024. It usually applies when you already own a residential property anywhere in the world. Specifically, a house you kept in Ohio counts. However, it does not apply if you disposed of your only or main residence in the 36 months before buying. Sell the US home within 36 months after buying, and you can generally claim the supplement back.

Nothing to deduct in the US

Under section 164(b)(6) of the Internal Revenue Code, individuals cannot deduct foreign real property taxes. The exception is tax paid in a trade, business or investment activity. Council tax is therefore no help on your US return. LBTT, by contrast, is a transfer tax. IRS Publication 551 includes transfer taxes in the cost basis of property you buy. Keep the LBTT return, because it raises your US basis when you later sell. Our article on a US person selling UK property covers that sale.

Your move-year checklist

Work through these steps in order for the year you move into, out of, or within Scotland. Each step changes a figure on one of your two Americans in Scotland tax returns.

Before the move

First, settle UK residence and whether split year treatment applies. Next, count how long your main home will sit in each part of the UK from 6 April. A move date near the halfway point can flip the answer. Note that before you sign a lease, since the result swings the whole year.

After the move

Then update your address with HMRC, and check that your code starts with S, or loses it. After that, watch your payslips for the backdated catch-up. If you buy a home, check whether you own any other dwelling worldwide. Then diarise the 36-month window.

At filing time

Finally, use the final UK figure, not the payslip total, for your Form 1116. Record the excess credit by category and carry it forward. Your Self Assessment return, if you file one, should show Scottish taxpayer status correctly. Our UK Self Assessment service page explains when one is needed.

How US UK Tax Experts can help

US UK Tax Experts prepares your US and UK returns from one file, so the two agree. For a move year, we work out your Scottish taxpayer status and check the UK figure against your payslips. We also price your foreign tax credit and carryover. Where a move date is still open, we can model both ways for each return. Americans in Scotland tax files often carry years of credit history, and we keep that schedule up to date.

Conclusion

The Scottish taxpayer test settles your rates for a whole UK tax year. Consequently, your move date can move your UK bill by well over a thousand pounds. On the US side, the higher Scottish rate rarely changes what you owe, but it grows your excess credit. Meanwhile, a kept American home can add an 8% supplement to a Scottish purchase. In short, Americans in Scotland tax work rewards a few early checks in the move year.
