Slough tax returns for workers, businesses and landlords

Who needs a Self Assessment return in Slough?

Quick answer: you need one if you are self-employed, let property, have dividends, gains or foreign income, or HMRC asks you to file.

As a Slough tax return accountant we work with self-employed drivers and logistics workers serving Heathrow and the trading estate, tech employees with share schemes, family-run shops and restaurants, landlords across Berkshire, and families with property or savings abroad.

Common reasons HMRC needs a tax return

• Sole trader or partnership income
• Property income from UK or overseas lets
• Company dividends over the allowance
• Taxable gains on investments or property
• Foreign income or gains
• Income over £100,000 or the Child Benefit Charge
• An HMRC notice to complete a return

Self-employed tax returns in Slough

Drivers can claim mileage or a share of vehicle costs, phone, insurance and platform fees. We compare methods and make sure your return is accurate and complete. See self-employed accountants and add bookkeeping if you would like records kept for you.

Landlord tax returns in Slough

Berkshire landlords face the same rules as London: mortgage interest relief as a tax credit, Making Tax Digital as thresholds fall and new property tax rates from April 2027. We prepare clear returns and keep you ahead of changes. 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.

Share schemes at work

Many Slough tech and corporate employees receive shares through SAYE, SIP, RSU or option schemes. Some are taxed through payroll, but selling shares can create Capital Gains Tax, and the base cost is easy to get wrong. We calculate gains correctly and report them on your return.

Partnership tax returns

Partnership returns trip people up because a late SA800 can mean a penalty for every partner. We prepare the SA800 and each partner’s return on one timetable. See partnership tax returns.

Capital Gains Tax reporting

Capital Gains Tax applies when you sell assets for more than you paid. The first £3,000 of gains is tax-free; above that, rates are 18% or 24%, with 60 days to report UK residential property. Our Capital Gains Tax team handles both returns.

Foreign income reporting

Foreign income is one of the most common reasons HMRC writes to people. We report it correctly, claim double tax relief and, if needed, use the Worldwide Disclosure Facility for earlier years.

Crypto tax reporting

Exchange reports rarely follow HMRC’s matching rules. We rebuild your crypto gains properly and report staking income. See crypto tax returns.
