UK & Overseas Property Business: Tax Rules You Need to Know

Aug 3, 2025

Property taxes can be confusing—especially when dealing with both UK and overseas rentals. In this episode of the I Hate Numbers podcast, Mahmood simplifies the rules for landlords, including how to report income, claim expenses, and avoid common mistakes that cost money.

Main Topics & Discussion

UK Property Income

  • Tax applies to rental income from UK property, regardless of where you live.
  • Includes residential, commercial, furnished holiday lets, and even part of your home if rented.
  • Must declare gross rents, allowable expenses, and profit on your tax return.

Overseas Property Income

  • UK residents pay tax on worldwide rental income.
  • Double Taxation Relief may apply if tax is also paid abroad.
  • Exchange rates must be considered when reporting foreign income.

Allowable Expenses

  • Deductible costs include repairs, letting agent fees, insurance, and utilities (if landlord-paid).
  • Mortgage interest relief is restricted and subject to tax credit rules.
  • Improvement costs are capital, not revenue, so not immediately deductible.

Property Ownership Structures

  • Rental profits are taxed on the legal owner(s).
  • Joint ownership splits income for tax purposes.
  • Using a company for property may offer tax advantages but adds complexity.

Common Mistakes to Avoid

  • Forgetting to declare overseas rental income.
  • Mixing personal and rental expenses without evidence.
  • Ignoring currency conversion rules.
  • Missing out on capital allowances or reliefs for certain property types.

Final Thoughts

Tax on property income doesn’t have to be overwhelming. Understand what’s taxable, keep good records, and use reliefs wisely. Whether your property is in the UK or abroad, planning and compliance are key to keeping more of your money.

Welcome to this week's I Hate Numbers episode.

Speaker:

Now in this week, I'm gonna be talking

Speaker:

about property with particular reference

Speaker:

to property that might be owned, not just in

Speaker:

the United Kingdom, but also overseas.

Speaker:

Now, if you've got rental income in say,

Speaker:

Birmingham, Leicester, Barcelona, or all three.

Speaker:

And this episode is for you.

Speaker:

Now, if you are thinking one property business

Speaker:

covers everything, covers all the properties,

Speaker:

again, unfortunately, you're gonna have to

Speaker:

rethink that thought.

Speaker:

Now, let's clarify.

Speaker:

If you've got property income in the United

Speaker:

Kingdom and property income overseas, you

Speaker:

are essentially from the HMRC perspective,

Speaker:

running two separate property businesses.

Speaker:

It may not feel like it, but that's the rules.

Speaker:

Now, if you've got just one house in Manchester.

Speaker:

One flat in say Milan, HMRC will treat them

Speaker:

differently and you know what's gonna happen

Speaker:

if you get it wrong, it's gonna cost you.

Speaker:

So let's crack off.

Speaker:

Firstly, what is the idea of a UK

Speaker:

property business?

Speaker:

Now, that's anything you rent out there,

Speaker:

that could be houses, flats, shops, holiday

Speaker:

homes, all of it counts.

Speaker:

It could be a buy to let in Leicester.

Speaker:

A shop in Luton or a cozy cottage

Speaker:

in Cornwall is all considered part of your

Speaker:

UK property business.

Speaker:

Now, it doesn't matter if you are using

Speaker:

a managing agent.

Speaker:

A letting agent to manage those properties for you.

Speaker:

Collect the rents, get your tenants in.

Speaker:

You are the one ultimately still

Speaker:

running the show.

Speaker:

HMRC will see the income is yours, not your agent,

Speaker:

so you can't abrogate your responsibility.

Speaker:

Now, if you own several properties

Speaker:

all in your name, they count and constitute

Speaker:

one UK business.

Speaker:

That means when it comes to the accounts

Speaker:

preparation, ultimately all the income is

Speaker:

aggregated together.

Speaker:

All your property expenses are aggregated

Speaker:

together, and you look at it as one

Speaker:

unit, essentially.

Speaker:

So if one flat makes a loss, another makes

Speaker:

a profit, you'll be able to offset them

Speaker:

against each other.

Speaker:

Sounds pretty neat.

Speaker:

Now, here's a bit of a twist in the tail.

Speaker:

If you own a property jointly with somebody

Speaker:

else, maybe your spouse, a friend, you might own

Speaker:

one through a limited company, then that's

Speaker:

not gonna be the same business anymore.

Speaker:

For HMRC is about what they call legal capacity.

Speaker:

That's what determines whether it's a separate

Speaker:

business or not.

Speaker:

Let's imagine a scenario.

Speaker:

We have Louise.

Speaker:

She owns two buy-to-lets and a holiday cottage

Speaker:

in her own name that counts as one UK

Speaker:

property business.

Speaker:

But she also happens to own a commercial

Speaker:

unit with her friend Archibald.

Speaker:

Now that is considered a partnership.

Speaker:

That's a different legal setup, and that's

Speaker:

another separate UK property business.

Speaker:

So that's one person, Louise.

Speaker:

But she's considered to have two property

Speaker:

businesses all located in the United Kingdom.

Speaker:

Now you may get a flavor of why legal

Speaker:

capacity matters.

Speaker:

It shapes how your income is taxed.

Speaker:

Emit that and you'll OMI tax savings or

Speaker:

trigger potential penalties and interest.

Speaker:

Let's look at the overseas property

Speaker:

business and ultimately we have

Speaker:

to keep it separate.

Speaker:

And when I say keep it separate, both in

Speaker:

terms of record keeping, calculations and tax.

Speaker:

Now let's visualize ourselves on that

Speaker:

plane, and if you rent a property outside the

Speaker:

uk, HMRC will view that.

Speaker:

As a overseas property business, the country

Speaker:

in which is located by the way, will

Speaker:

also get involved.

Speaker:

So you might own a long term rental.

Speaker:

In Portugal, a ski shall in Nu and a studio in

Speaker:

Cyprus, they go into a separate tax pot.

Speaker:

Now think of it like this.

Speaker:

Your UK property is your first bucket.

Speaker:

The overseas property is bucket number two.

Speaker:

You cannot pour between them.

Speaker:

So if you do make a loss, perhaps on

Speaker:

a Spanish filler.

Speaker:

That's unfortunate, but you can't use

Speaker:

that overseas loss to reduce your UK tax

Speaker:

bill, which that you could, but unfortunately

Speaker:

blames the rules.

Speaker:

Now, there is a new thing for overseas

Speaker:lords, and that's from April,:Speaker:

If you had a furnished holiday letter in

Speaker:

the EEA, the European economic area.

Speaker:

It got special treatment.

Speaker:

It was considered separate from your

Speaker:

long-term overseas LEDs.

Speaker:

Unfortunately, post April 25, there's a change.

Speaker:

An HMRC says, all overseas properties,

Speaker:

irrespective of type of property, must be

Speaker:

treated as one overseas property business, so

Speaker:

long as you're in the same legal capacity.

Speaker:

IE.

Speaker:

You might own them all yourself if you've got

Speaker:

properties overseas, but you've got

Speaker:

partnerships perhaps, or split ownership

Speaker:

on those, that's considered separate

Speaker:

in its own rights.

Speaker:

Now let's introduce another example

Speaker:

into the mix.

Speaker:

Let's imagine Peter, he owns four Residential

Speaker:

Lets in Leeds, a commercial unit in

Speaker:

Bolton, and two holiday cottages in Cornwall.

Speaker:

That counts as one UK property business.

Speaker:

Now Peter also owns a Paris apartment.

Speaker:

On a holiday flat in Barcelona.

Speaker:

That's a overseas property business,

Speaker:

one overseas property business.

Speaker:

Now, the Parisian losses can't be used

Speaker:

to offset the tax that might be due in

Speaker:

Barcelona and vice versa.

Speaker:

It's a clear differentiator, it's a

Speaker:

clear line in the sand.

Speaker:

So ultimately, why does any of this matter?

Speaker:

Well, it's quite simple in a sense of it's about

Speaker:

tax, it's about money, and it's about clarity

Speaker:

and peace of mind.

Speaker:

If you get your business property structure wrong

Speaker:

and it's very possible you could, you are

Speaker:

gonna miss out on those valuable tax release,

Speaker:

you are gonna file the wrong tax return.

Speaker:

You're gonna end up with penalties, you'll be

Speaker:

oblivious to any double tax changes might exist.

Speaker:

Or worse, you'll pay more tax than you need to.

Speaker:

And remember, this applies even if you own

Speaker:

only one property now.

Speaker:

'cause that could change quite rapidly.

Speaker:

So let's do a bit of a recap about

Speaker:

the essentials.

Speaker:

If you earn from property, you are

Speaker:

running a business.

Speaker:

Now, HMRC might not see it as a trading business,

Speaker:

but it's a business.

Speaker:

Nevertheless, UK and overseas property are

Speaker:

not the same business.

Speaker:

We need to differentiate them and we need to

Speaker:

also make sure we got good, adequate records

Speaker:

to support that.

Speaker:

If you own all your UK properties in

Speaker:

your name, treat them as one business.

Speaker:

If you have UK properties and there are other

Speaker:

parties involved with an ownership element there,

Speaker:

then they are separated.

Speaker:

Now, overseas properties is the same rationale.

Speaker:

One business in the legal setup is

Speaker:

the same different legal capacities.

Speaker:

Means and equates to separate businesses.

Speaker:

Now, tax rules, as we know, aren't

Speaker:

designed to be simple.

Speaker:

If they were, life would be nicer.

Speaker:

You put a lot of tax advisors like myself out

Speaker:

of business, but hey, now if you're finding

Speaker:

this problematic, talk to your accountant.

Speaker:

Talk to your tax advisor.

Speaker:

If not, drop us a line.

Speaker:

We help landlords just like you understand

Speaker:

where you stand and if you fancy a nice, easy,

Speaker:

humorous, read the full picture of money Tax

Speaker:

of business, or grab a copy of my book.

Speaker:

I hate numbers.

Speaker:

It's practical.

Speaker:

It's straight talking.

Speaker:

It's well received, and it may be just the

Speaker:

most valuable thing you've read this year.

Speaker:

The fakes.

Speaker:

Well, I hope you found this episode useful.

Speaker:

Share it with somebody else, a fellow landlord,

Speaker:

a property investor, maybe a friend of yours

Speaker:

who think their Barcelona fan is tax free.

Speaker:

And remember, whatever you do with your numbers,

Speaker:

plan it, do it, and profit until the next

Speaker:

time they sandwich.
