If you’re a British or Irish owner selling an apartment or holiday home in Sunny Beach, Bulgaria, one of the first questions is usually: “Will the UK tax me as well?” The short answer is: if you’re UK tax resident, the UK can tax your gain on overseas property—but you may be able to offset Bulgarian tax under the UK–Bulgaria tax treaty rules.
This guide explains how it works in practice, what typically gets taxed in Bulgaria, how the UK calculates Capital Gains Tax (CGT), and how to avoid common (and expensive) mistakes when selling in Sunny Beach.
The key rule: UK tax depends on your UK tax residence (not where the property is)
The UK taxes UK residents on worldwide gains, which includes gains from selling property in Bulgaria. GOV.UK is explicit: if you’re resident in the UK and dispose of overseas property, UK CGT can apply.
If you’re not UK tax resident, the UK generally does not charge CGT on the sale of foreign property—but there are important exceptions (especially if you left the UK temporarily).
Can Bulgaria tax the sale too?
Yes. Bulgaria generally has the right to tax gains from Bulgarian real estate—because the property is located in Bulgaria. This is also the standard approach in tax treaties for “immovable property.” The current UK–Bulgaria treaty text (2015 convention, now in force) supports that Bulgaria may tax gains on Bulgarian immovable property.
So in many real-world cases, a UK resident seller can face:
- Bulgarian tax rules, and
- UK CGT rules
…but you usually should not pay full tax twice on the same gain because the UK can give double tax relief where appropriate.
How Bulgaria typically taxes individuals selling property
Bulgaria commonly applies a flat 10% tax to taxable capital gains for individuals (and the tax position can depend on how you acquired the property and how long you’ve owned it).
There are also widely used exemptions in Bulgarian rules for individuals, for example:
- One residential property can be non-taxable if owned more than 3 years
- Up to two properties can be non-taxable if owned more than 5 years
(Conditions matter; exact eligibility depends on your personal situation and the property type.)
Because Bulgarian exemptions can be very valuable, sellers in Sunny Beach should be careful about how the property is described and documented (residential vs. other use, dates of acquisition, inheritance documents, etc.).
How the UK taxes the sale: UK CGT on an overseas property gain
If you are UK tax resident, the UK charges CGT on the gain (profit), not the sale price. GOV.UK confirms UK residents pay CGT when disposing of overseas property.
Step 1: Work out your gain (in sterling)
In broad terms, your gain is:
Sale proceeds
minus purchase price
minus allowable buying/selling costs
minus qualifying capital improvement costs
Allowable costs often include legal fees, agents’ fees, and certain improvement works (not normal repairs/maintenance). (A tax adviser can confirm what is allowable for your situation.)
Important: because the property is in Bulgaria, you still calculate the gain for UK tax purposes in GBP. Exchange rate movements can affect the gain in sterling terms even if the local-currency price change looks small.
Very important: If you’ve owned the property for more than three years, selling it is tax-free.
Step 2: Apply UK CGT allowance (if available)
UK individuals have an annual exempt amount (CGT allowance). It has been reduced in recent years (e.g., GOV.UK shows the allowance framework and rates; your exact allowance depends on the tax year and your circumstances).
Step 3: Apply the UK CGT rate that matches your income band
For residential property gains, GOV.UK shows rates from 6 April 2025 onwards as:
- 18% for gains that fall within the unused basic rate band
- 24% for gains above that band (higher/additional rate territory)
(Residential property rates changed in April 2024, reducing the higher rate from 28% to 24%.)
Do you have to report the overseas sale to HMRC?
Usually, yes—if you’re UK resident and you have a taxable gain, you normally report it via Self Assessment for the tax year in which you sold. GOV.UK’s overseas property guidance points you to UK CGT being due for UK residents.
Also note: the “60-day CGT reporting” rule is specifically a major feature of UK property disposals; overseas sales are typically handled through Self Assessment rather than the UK property reporting service. (If your wider situation is complex, get advice.)
How double tax relief usually works (so you don’t pay twice)
If Bulgaria taxes the gain and the UK also taxes the gain because you’re UK resident, you may be able to claim Foreign Tax Credit Relief in the UK—meaning the UK tax bill can be reduced by the Bulgarian tax paid on the same gain (up to the UK tax attributable to that gain). GOV.UK confirms relief may be available if you’re taxed twice.
Practical reality for many Sunny Beach sellers:
- If Bulgaria taxes at (for example) 10% and your UK CGT rate is 18%/24%, you might effectively pay a “top-up” in the UK (depending on calculations, reliefs, and how each country defines the taxable gain).
- If Bulgaria’s exemption applies and you pay no Bulgarian tax, you can still owe UK CGT if you’re UK resident, because UK rules are separate.
Special situations that change the answer
Here are the scenarios that most often catch British owners out:
1) You live outside the UK now
If you’re non-UK resident, you’re generally not charged UK CGT on foreign property—but the UK has temporary non-residence rules that can bring gains back into charge when you return. HMRC guidance flags different rules for temporary non-residents.
2) The property was your main home at some point
The UK has Private Residence Relief (PRR), which can reduce/erase UK CGT if the property was your only/main residence for qualifying periods. However, a Sunny Beach property is often a holiday home, so PRR frequently doesn’t apply (or applies only partially).
3) You jointly own the property (spouse/partner)
Joint ownership can change the tax calculation because each owner calculates gains and allowances separately. Many couples reduce overall tax by using both annual exemptions and (where appropriate) splitting gains, but the exact outcome depends on ownership structure and residency.
4) You inherited the property
Bulgarian rules can treat inherited property differently, and documentation matters.
In the UK, inherited property has its own base cost rules (commonly linked to probate value), so it’s worth getting professional confirmation before you assume the “purchase price.”
Sunny Beach seller tip: tax accuracy starts with sale structure and paperwork
A lot of UK tax stress comes from messy documentation:
- missing proof of acquisition costs
- unclear improvement invoices
- unclear ownership shares
- incorrect dates
- wrong seller details on draft contracts

Common mistakes British sellers make (and how to avoid them)
- Assuming “tax is only in Bulgaria.” UK residency can still trigger UK CGT.
- Assuming “I’ll pay tax twice.” Double tax relief may apply if both countries tax the same gain.
- Not keeping improvement invoices. Some improvements can reduce the taxable gain (rules apply).
- Overpricing and sitting on the market. In Sunny Beach, pricing strategy matters because buyer demand is very price-sensitive.
- Using non-local agents. Poor local coordination can delay notary steps and completion, and mistakes can be costly.
