How many UK companies file accounts in a foreign currency?
By Ben Davies · Updated 4 November 2026
We file your accounts and tax return for £19/year
File my dormant accountsIn the 12 months to September 2026, 4,667 of the 3,747,476 sets of accounts in Companies House's digital data weren't in pounds. That's about 1 in 803, from 4,419 companies. We couldn't find this figure published anywhere, so we counted them ourselves.
The short version
- Euros come first, with 2,915 filings (62%). US dollars follow with 1,419 (30%).
- Norwegian kroner come third, with 273 filings, and every one is a set of dormant accounts.
- Dormant companies stand out. They make up 16% of all filings but 46% of those not in pounds.
- LLPs are about 14 times more likely than companies to file in another currency.
- Micro-entity accounts are the least likely, at about 1 in 4,900.
Which currencies
| Currency | Filings |
|---|---|
| Euros | 2,915 |
| US dollars | 1,419 |
| Norwegian kroner | 273 |
| Australian dollars | 25 |
| Swiss francs | 6 |
| Indian rupees | 5 |
| Canadian dollars | 5 |
| Hong Kong dollars | 3 |
| 13 other currencies | 16 |
| Total | 4,667 |
The other 13 are mostly a single filing each, from Afghan afghani to Gambian dalasi. We report what the filings state. Some of those one-offs may be slips rather than real choices, and we can't check them.
The surprise: Norwegian kroner
Kroner outnumber every currency outside euros and dollars put together: 273 filings against 60. They stand out in other ways too:
- Every one is dormant accounts. For euros it's about half (1,528 of 2,915), and for US dollars about one in five (288 of 1,419).
- They come from 272 different companies, so this isn't one company catching up on old years.
- 175 arrived in one month, January 2026, and 172 of those had a December 2025 year end. A company has nine months to file, so these were filed within weeks.
- Nearly four in five (212) have company numbers starting 05, 06 or 07, which points to companies formed well over a decade ago.
The filings don't say why. To us it looks more like a yearly routine than hundreds of separate decisions, but that's our reading and the data can't prove it.
Which accounts and which companies
| Type | All filings | Not in pounds | Rate |
|---|---|---|---|
| Dormant accounts | 593,737 | 2,145 | 1 in 277 |
| All other accounts (small, full and so on) | 1,404,278 | 2,165 | 1 in 649 |
| Micro-entity accounts | 1,749,461 | 357 | 1 in 4,900 |
| Entity | All filings | Not in pounds | Rate |
|---|---|---|---|
| LLPs (limited liability partnerships) | 28,207 | 457 | 1 in 62 |
| Companies | 3,719,269 | 4,210 | 1 in 883 |
Dormant accounts dominate once you leave euros and dollars: 329 of the 333 filings in any other currency are dormant. LLPs go the other way, with 420 of their 457 filings being fuller accounts rather than dormant or micro-entity ones.
When they arrive
| Companies House's monthly file | All filings | Not in pounds |
|---|---|---|
| October 2025 | 304,409 | 361 |
| November 2025 | 298,461 | 317 |
| December 2025 | 499,784 | 581 |
| January 2026 | 289,256 | 408 |
| February 2026 | 258,471 | 271 |
| March 2026 | 342,574 | 359 |
| April 2026 | 263,094 | 235 |
| May 2026 | 258,176 | 275 |
| June 2026 | 296,554 | 273 |
| July 2026 | 294,538 | 374 |
| August 2026 | 260,186 | 337 |
| September 2026 | 381,973 | 876 |
September is the peak, and most of it is the filing deadline: 767 of its 876 filings have a December 2025 year end. Private companies have nine months to file, so a 31 December year end falls due on 30 September.
If your company is one of them
Filing in another currency is allowed. Companies House accepts accounts in other currencies, and shares can be in any currency. The Company Tax Return is always in pounds, though a nil return has nothing to convert. If you run the company from outside the UK, see our guide to managing a dormant UK company from abroad.
Why a simple search gets this wrong
Search this data for "EUR" and you'll overcount hugely, because many filings declare currencies they never use. On one sample day, 4 November 2026, 2,792 of 9,684 filings declared a currency other than pounds, yet only 14 used one for any figure. That's about 200 times too many.
Labels can mislead the other way too. Some filings name their money unit "GBP" while measuring euros. So we ignored the names and read what the figures themselves are measured in.
How we counted
- Source: the 12 monthly files from October 2025 to September 2026 in Companies House's free Accounts Data Product. It holds accounts filed digitally, so paper filings aren't counted.
- Not in pounds: a filing counts when its net assets or equity are measured in another currency. If neither is tagged, we used its first money figure. Per-share units are ignored.
- Accounts type: dormant if tagged dormant or claiming the dormant audit exemption, micro-entity if tagged or worded as micro-entity, and everything else is "all other". LLPs are identified by company numbers starting OC, SO or NC.
- Filings, not companies: a company can file more than once in a year, which accounts for the other 248 filings.
- Checks: in 4,635 of the 4,667 the currency also appears at the top of the balance sheet. In 28 it isn't clear, and 4 show pounds there despite the tag. We also read a sample by hand. A pound sign elsewhere usually turned out to be a note about sterling, or shares with a £1 par value.
- Left out: 2,631 compressed files in the data, which we didn't open. Another 8,323 filings tag no currency at all and count towards the total only.
The filings are public, but we've named no companies here.
