-
Statutory Compliance
-
Financial Control
-
Strategic Tax Efficiency
This approach allows businesses not only to remain compliant but to grow with clarity and confidence.

Unlike employees, self-employed professionals must manage:
-
Income reporting
-
Allowable expenses
-
National Insurance contributions
-
VAT obligations
-
Tax deadlines
-
HMRC correspondence
Mistakes can lead to penalties, investigations, and unnecessary tax payments.

We advise on:
-
Sole trader vs limited company comparison
-
Tax efficiency differences
-
Liability protection
-
Income level considerations
-
Long-term business goals
Choosing the wrong structure can increase tax liability unnecessarily.
We ensure you start correctly.
Sole Trader Tax Obligations Explained
As a self-employed professional in the UK, you are responsible for:
-
Filing annual Self Assessment tax return
-
Paying Income Tax
-
Paying Class 2 and Class 4 National Insurance
-
Registering for VAT (if turnover exceeds threshold)
-
Keeping financial records
Deadlines matter.
Late filing penalties start automatically — even if no tax is due.
We manage all submissions to prevent compliance risks.
Self Assessment Tax Return – Complete Handling
Preparing a Self Assessment return involves more than inputting income.
We perform:
-
Income verification
-
Allowable expense analysis
-
Tax relief review

Home office costs
-
Travel and mileage
-
Equipment and software
-
Professional subscriptions
-
Insurance premiums
-
Marketing expenses
We ensure full compliance while maximising legal deductions.
National Insurance & Payment on Account Planning
Self-employed individuals often underestimate:
-
Class 2 NI
-
Class 4 NI
-
Payments on account
Payments on account require advance tax payments toward the following year.
Without planning, this creates unexpected financial pressure.
We forecast liabilities to avoid surprises.
CIS – Construction Industry Scheme Support
London has one of the largest construction sectors in the UK.
CIS rules can be complex and frequently misunderstood.
We support:
-
Contractors
-
Subcontractors
-
Construction companies

Under CIS, contractors deduct 20% from payments to registered subcontractors.
We help with:
-
CIS registration
-
Deduction verification
-
Monthly deduction tracking
-
Reclaiming overpaid tax

Many subcontractors overpay tax throughout the year.

-
Register for CIS
-
Verify subcontractors
-
Deduct correct percentage
-
File monthly CIS returns
-
Maintain payment and deduction statements
Failure to submit monthly returns results in automatic penalties.
We manage full CIS compliance, including:

Should I operate as a sole trader or a limited company?
We analyse:
-
Annual income

Liability risks
-
Long-term tax impact
For higher-earning contractors, limited companies often provide:
-
Greater tax efficiency
-
Director dividend planning
-
Pension contribution advantages
-
Personal liability protection
But structure must be chosen carefully.
We provide clear comparative modelling.

IR35 determines whether a contractor is effectively operating as an employee for tax purposes.
We assess:
-
Contract wording

Working practices
-
Substitution rights
-
Control level
-
Financial risk factors
Incorrect IR35 classification can result in:

We provide:

What Triggers HMRC Investigations?
HMRC may review accounts due to:

-
Large expense claims
-
Late filings
-
VAT irregularities

Bank statements
-
CIS deduction statements
-
VAT invoices
-

Corporation tax relief (for directors)
-
Long-term retirement planning integration
Strategic pension contributions can significantly reduce taxable income.

Frequently Asked Questions
How much does an accountant cost in London?
Fees vary depending on business complexity, transaction volume, and services required. Fixed monthly packages provide predictable costs for most SMEs.
Do I need to register for VAT in the UK?
VAT registration becomes mandatory once turnover exceeds the threshold set by HMRC. Voluntary registration may be beneficial in certain circumstances.
What happens if I file my tax return late?
HMRC applies automatic penalties for late Self Assessment, VAT, and corporation tax submissions. Additional interest may accrue on unpaid tax.
Can you reduce my corporation tax legally?
Yes. Through structured planning such as allowable expense optimisation, director remuneration structuring, pension contributions, and relief utilisation.
How long does company formation take in the UK?
Most Companies House registrations are completed within 24–48 hours, subject to documentation accuracy.
What is the Construction Industry Scheme (CIS)?
CIS requires contractors to deduct tax from subcontractor payments and submit monthly returns to HMRC.
What is IR35 and does it apply to me?
IR35 legislation determines whether contractors working through limited companies should be taxed as employees. We assess contract terms to determine exposure.

Yes. We represent clients in correspondence, prepare documentation, and manage formal appeals.
