Self Assessment Tax Returns
Self Assessment is the HMRC system through which millions of individuals report income not taxed at source and pay any tax owed. Whether you are self-employed, a landlord, a company director, or a higher-rate taxpayer, I prepare your return accurately, claim every allowable deduction, and file directly with HMRC — removing the stress and risk of doing it yourself.

- 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

- Landlords with rental income

Corporation Tax
Corporation Tax Returns (CT600)
Every UK limited company must file a Corporation Tax return (CT600) each year, along with statutory accounts, regardless of whether it made a profit. I prepare your company accounts, calculate your Corporation Tax liability, identify legitimate reliefs including capital allowances and R&D credits, and file with both 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.
Self Assessment + Corporation Tax — handled together
Most limited company directors need both a personal Self Assessment return and a corporate CT600. I handle both as a coordinated service, ensuring salary, dividends, and company profit are structured as tax-efficiently as possible. One accountant. One relationship. Both returns.
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 been filing my own Self Assessment for years and always worried I was getting it wrong. She reviewed everything, found deductions I had missed, and my tax bill was lower than it had ever been. I will never do it myself again.

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.
