UK Personal Tax —
Every Relief You’re Owed
From Self Assessment and Capital Gains Tax to landlord income, non-resident UK tax and inheritance tax planning, Britvex provides personal tax support for individuals with UK tax obligations. We review the relevant facts, filing requirements and available reliefs before advising on the appropriate treatment.
Everything Covered —
Personal Tax Made Simple
Whether you’re self-employed, a landlord, company director, freelancer, investor or an individual with UK filing obligations, Britvex can support the personal tax work included in your engagement and explain the information HMRC requires.
Self Assessment Tax Return
Personal Self Assessment support for self-employed individuals, landlords, directors and others who need to file. The work can include registration, preparation, allowable-expense review, relief claims and submission where included in the engagement.
Learn More →Capital Gains Tax (CGT)
Capital Gains Tax support for property, shares and other chargeable disposals, including calculation, reporting and consideration of relevant reliefs such as Private Residence Relief or Business Asset Disposal Relief where the conditions are met.
Learn More →Landlord & Rental Income Tax
UK landlord tax support covering rental income, allowable property expenses, finance-cost restrictions and reporting obligations. The former furnished holiday lettings tax regime was abolished from April 2025, so short-term lets are now generally taxed under the ordinary property-income rules.
Learn More →Non-Resident UK Tax
UK tax support for non-residents and internationally mobile individuals with UK income or assets, including property income, employment income, pensions and UK property disposals. Residence status and treaty positions are reviewed where relevant.
Learn More →Inheritance Tax Planning
Inheritance Tax planning support can include reviewing the estate, available nil-rate bands, gifting rules, trusts and Business Relief where relevant. From 6 April 2026, 100% Agricultural and Business Relief is generally capped at a combined £2.5 million qualifying allowance, subject to the detailed rules.
Learn More →Marriage Allowance
Marriage Allowance lets an eligible lower-earning spouse or civil partner transfer £1,260 of Personal Allowance, reducing the other partner’s tax by up to £252 for the tax year. Claims can also be backdated for eligible earlier years within HMRC’s permitted window.
Learn More →HMRC Penalty Appeals
Received an HMRC penalty, enquiry or compliance notice? Britvex can review the facts, correspondence and filing history, then help prepare an appeal or response where there is a reasonable basis and the work is within the engagement scope.

Key Personal Tax Deadlines — Don’t Miss These
Missing a UK tax deadline can lead to penalties, interest or additional compliance work. These are some of the recurring dates that commonly matter, although the exact deadline can depend on the individual facts.
Personal Tax Questions
When is the online Self Assessment deadline?
The normal online filing deadline is 31 January following the end of the tax year. Any balancing payment and the first payment on account, where applicable, are also normally due on 31 January.
When is the second Self Assessment payment on account due?
The second payment on account is normally due on 31 July. Payments on account generally apply where the previous Self Assessment bill exceeds £1,000 unless more than 80% of the tax was collected outside Self Assessment.
How quickly must UK residential-property Capital Gains Tax be reported?
Where a UK residential-property disposal gives rise to reportable Capital Gains Tax, the normal reporting and payment deadline is 60 days from completion. Different reporting rules can apply to non-residents.
How much can Marriage Allowance save?
An eligible lower-earning spouse or civil partner can transfer £1,260 of Personal Allowance, reducing the other partner’s tax by up to £252 for the tax year.
Do the old furnished holiday letting tax rules still apply?
No. The special Furnished Holiday Lettings tax regime was abolished from April 2025. Short-term holiday accommodation is now generally taxed under the ordinary property-income rules, subject to the facts of the case.
