Tax Returns for Windsor & the Royal Borough

Windsor and the Royal Borough has a high concentration of professionals, landlords, directors, and business owners — many with complex tax returns involving multiple income streams, rental portfolios, directorships, or share scheme income. I provide a complete, managed tax return service tailored to each client’s situation.

Windsor’s proximity to London, Heathrow, and the M4 corridor means many residents have complex employment arrangements — cross-border work, multiple directorships, or non-resident periods. I handle all of these within the Self Assessment framework correctly.

Areas Covered

  • Windsor Town Centre & Eton
  • Old Windsor & Datchet
  • Clewer & Dedworth
  • Maidenhead & Taplow
  • Ascot, Sunninghill & Virginia Water
  • Marlow & Cookham

Remote and in-person meetings available.

Self Assessment

Self Assessment for Windsor Residents

Windsor residents often have returns that go beyond simple employment income — rental properties, director’s dividends, share schemes, and investment income are all common. I prepare your Self Assessment return completely, ensure every eligible deduction is claimed, and file directly with HMRC.

What’s Included

  • Reviewing all income sources (employment, rental, dividends, investments)
  • Calculating all allowable expenses & deductions
  • Preparing & filing your Self Assessment with HMRC
  • Calculating tax liability & payment on account
  • HMRC correspondence & enquiry handling
  • Proactive tax-saving advice
  • Reminders for deadlines (31 Jan & 31 Jul)
  • Year-round support — not just at return time

Who Is This For?

  • Self-employed sole traders & freelancers
  • Limited company directors
  • Landlords with rental income
  • Higher-rate taxpayers with untaxed income
  • Individuals with investment or dividend income
  • Employees earning over £100,000
  • Anyone with overseas income
  • Those who received an HMRC Self Assessment notice
Corporation Tax

Corporation Tax for Windsor Companies

Windsor’s business community spans hospitality, professional services, construction, and retail. Every limited company must file a Corporation Tax return annually. I prepare statutory accounts and CT600 returns, identify capital allowances and reliefs, and file with HMRC and Companies House.

What’s Included

  • Statutory accounts preparation (Companies House compliant)
  • Corporation Tax computation & CT600 filing
  • Director’s Self Assessment (if required)
  • Capital allowances calculation & claims
  • R&D tax relief identification & claims
  • HMRC correspondence & enquiries
  • Dividend planning & tax-efficient profit extraction advice
  • Year-end review meeting

Who Is This For?

  • All UK limited companies (every year, even if dormant)
  • Community Interest Companies (CICs)
  • Companies with investment income
  • Companies making a loss (return still required)
  • New companies in their first trading year
  • Holding companies & group structures

A CT600 must be filed within 12 months of the accounting period end — even if no tax is due.

Multiple income streams? I handle the complexity.

Many Windsor clients have rental income, directorship dividends, share scheme income, and employment income all in the same tax year. I prepare your Self Assessment to ensure every source is declared correctly and every allowable expense and relief is fully utilised.

The process

How It Works

Getting started is simple. Here’s what to expect:

1
Free Consultation

We discuss your situation — Self Assessment, Corporation Tax, or both. No obligation.

2
Information Gathering

You provide income, expense records, and documents. I make this easy with a clear checklist.

3
Return Preparation

I calculate your liability, identify every allowable deduction, and prepare your return.

4
Review & Approval

You review before anything is filed. I explain everything in plain language.

5
Filing & Follow-up

I file directly with HMRC, send confirmation, and set payment deadline reminders.

I had rental income, a directorship, and share scheme income all in the same tax year and had no idea how to declare any of it. She prepared a flawless Self Assessment, explained everything in plain language, and I did not have a single query from HMRC.
FAQ

Frequently Asked Questions

The online filing deadline is 31 January following the end of the tax year (5 April). Payment of any tax owed is also due by 31 January. Payments on account are due 31 January and 31 July. I send reminders well in advance.

Corporation Tax is due 9 months and 1 day after your accounting period ends. The CT600 filing deadline is 12 months after the period. For example, if your year-end is 31 March, payment is due 1 January and your CT600 by 31 March the following year.

Yes — most directors need a personal Self Assessment return in addition to the company CT600. This covers salary, dividends, and any other personal income. I handle both returns as a coordinated service.

For Self Assessment: P60/P45, self-employment income and expense records, rental income details, bank interest, dividend vouchers. For Corporation Tax: bank statements, invoices, receipts, payroll records, and asset purchases. I provide a clear checklist.

Pricing depends on complexity. A straightforward Self Assessment costs less than one with multiple income sources. Corporation Tax depends on company size. Book a free consultation for a transparent, fixed-fee quote.

Yes. I work with individuals and limited companies across Windsor and the Royal Borough entirely remotely. All documents are shared securely online and I file directly with HMRC on your behalf.

My primary service is delivered remotely, which is efficient and works well for the vast majority of clients. However, if you would prefer an in-person meeting to go through your return, I am happy to arrange this in Windsor or the surrounding area.
