United Kingdom Tax Compliance & Planning
Income tax, National Insurance, corporation tax, VAT, and payroll each carry distinct rules and deadlines. We help UK taxpayers and companies stay aligned with HMRC without drowning in paperwork.
Self-employed professionals, landlords, directors, and non-residents with UK income rely on us for accurate self-assessment and timely electronic submission.
For companies, we support corporation tax, VAT cycles, PAYE/RTI payroll, and ongoing reviews so records match current legislation.

In Detail
What Each Service Includes
Self-Assessment Tax Returns
Self-assessment applies to self-employed individuals, company directors, high earners, landlords, and anyone with untaxed income. We prepare your SA100 return with all required supplementary pages (SA103 for self-employment, SA105 for property, SA108 for capital gains), calculate your tax liability, and file electronically before the deadline.
Corporation Tax & Company Accounts
Limited companies must file corporation tax returns (CT600) and pay tax on profits within nine months and one day of the accounting period end. We work with your accounts, apply allowable deductions and capital allowances, and ensure your CT600 aligns with Companies House filing requirements.
VAT Registration & Returns
Businesses exceeding the VAT registration threshold must register with HMRC and submit periodic VAT returns. We advise on the most suitable VAT scheme (standard, flat rate, or cash accounting), prepare quarterly submissions, and help you reclaim input VAT on eligible business expenses.
PAYE, Payroll & RTI
Employers must operate PAYE, deduct income tax and National Insurance from employee wages, and submit Real Time Information (RTI) reports to HMRC on or before each payday. We manage payroll processing, P60 and P11D benefit reporting, and auto-enrolment pension compliance.
HMRC Enquiries & Representation
If HMRC opens an enquiry into your return, time is critical. We liaise with HMRC on your behalf, prepare supporting schedules and explanations, negotiate settlements where appropriate, and help you understand your rights throughout the process.
Expat & Non-Resident Tax
Your UK tax residency status determines what income is taxable in the UK. We apply the statutory residence test, consider split-year treatment, and coordinate with foreign tax credits and double taxation agreements for clients who live, work, or invest across borders.

Key Topics
Important UK Tax Considerations
Self-Assessment Deadlines & Penalties
Online self-assessment returns are due by 31 January following the tax year end. Missing the deadline triggers automatic penalties that increase over time. We track your deadlines, send reminders, and file early to avoid last-minute issues.
Making Tax Digital (MTD)
MTD requires VAT-registered businesses to keep digital records and submit returns using compatible software. We ensure your VAT processes meet MTD requirements and advise on upcoming MTD for Income Tax Self Assessment (MTD for ITSA) obligations.
Capital Gains Tax
Selling property (other than your main residence), shares, or business assets may trigger capital gains tax. We calculate gains, apply annual exemptions and reliefs such as Business Asset Disposal Relief, and report on the relevant supplementary pages.
Tax Planning for Directors
Company directors can optimise their tax position through a combination of salary and dividends. We model the most tax-efficient extraction strategy while ensuring compliance with IR35 rules and National Insurance thresholds.

Frequently Asked Questions
You must register for self-assessment if you are self-employed, a company director, earn over £100,000, have untaxed income above £2,500, or receive income from property, investments, or foreign sources. We help determine whether registration is required.
The UK tax year runs from 6 April to 5 April the following year. Online self-assessment returns for the prior year are due by 31 January. Paper returns have an earlier deadline of 31 October.
You must register if your taxable turnover exceeds the VAT threshold (currently £90,000 in a rolling 12-month period). Voluntary registration may benefit businesses that primarily sell to other VAT-registered companies. We advise on timing and scheme selection.
