Self Assessment returns for Southwark, made straightforward

Do I need to file a tax return in Southwark?

The simple answer: you need a Self Assessment return if you have income outside PAYE, such as self-employment, rent, dividends or gains, or if HMRC sends you a notice to file.

As a Southwark tax return accountant we work with Peckham artists and studio holders, Bermondsey food producers and market traders, landlords in Camberwell and Walworth, and professionals around London Bridge with bonuses or share schemes. Each situation brings different allowances and pitfalls.

We explain the numbers clearly, so you understand what you owe, when it is due and how next year’s payments on account will work.

Common reasons HMRC needs a tax return

• You are self-employed or a partner in a business
• You earn rental income over £1,000
• You receive dividends above £500
• You made capital gains above £3,000
• You have foreign income
• You or your partner earn over £60,000 and get Child Benefit
• HMRC sent you a notice to file

Self-employed tax returns in Southwark

Food businesses need careful records of ingredients, packaging, market pitch fees, vehicle costs and equipment. We claim everything allowable and check whether you are approaching the VAT threshold, so there are no surprises. See self-employed accountants and add bookkeeping if you would like records kept for you.

Landlord tax returns in Southwark

With King’s College and other campuses nearby, many Southwark properties are let to students. We prepare landlord returns that capture rent, repairs, agent fees and furnishings, and explain how mortgage interest relief works for higher-rate landlords. Mortgage interest relief is a 20% tax credit, rising to 22% from April 2027 when property income gets its own 22%, 42% and 47% rates.

Approaching the VAT threshold

Growing food and creative businesses in Southwark often reach the £90,000 VAT registration threshold without noticing. Turnover is measured over a rolling 12 months, not the tax year. We monitor it alongside your tax return and can handle registration and returns through our VAT service.

Partnership tax returns

Partnerships, from family shops to professional practices, file a partnership return (SA800) plus each partner’s own return. We prepare both so the profit shares match. See partnership tax returns.

Capital Gains Tax reporting

Gains above the £3,000 annual exempt amount are taxed at 18% or 24%. A UK home you sell that is not your main residence must be reported, with tax paid, within 60 days of completion. Our Capital Gains Tax team handles both returns.

Foreign income reporting

UK residents are usually taxed on worldwide income, with foreign tax credit relief for tax paid abroad. Missed foreign income can be put right through the Worldwide Disclosure Facility.

Crypto tax reporting

Selling, swapping or spending crypto can create a gain, and staking is usually income. We apply HMRC’s pooling rules; see crypto tax returns.

What to send us for your Southwark tax return

Most clients only need a few documents. We send a tailored checklist after your first call.

• P60 or payslips from any employment
• Bank statements or invoices for self-employed income
• Receipts for business costs, or a simple spreadsheet
• Rent statements from your letting agent
• Mortgage interest statements for rental properties
• Dividend vouchers and investment statements
• Details of any overseas income and tax paid abroad

Penalties for late filing

What if I miss the deadline? For returns up to 2025/26: £100 immediately, £10 a day after three months (up to £900), then 5% or £300 at six and twelve months. A points-based system applies to everyone from April 2027.
