Managing your finances as a contractor is a different beast compared to salaried employment. As an accountant for contractors in London, H2 Accounting helps independent professionals manage their tax returns, National Insurance contributions, VAT registration, and IR35 responsibilities with confidence. Without the right support, these obligations can quickly become overwhelming. Based in London and serving contractors across England, H2 Accounting provides specialist accountancy services tailored to the way contractors actually work. Led by Abul Hasan, a Chartered Accountant (ICAEW) with over 10 years of experience—including significant tenure at KPMG—H2 Accounting brings big-firm expertise to independent professionals who deserve more than a one-size-fits-all service.
What Makes Contracting Tax So Complex?
Contracting comes with financial responsibilities that most people underestimate when they first go independent. Unlike permanent employees, contractors must navigate:
- Self-assessment tax returns filed annually with HMRC
- VAT registration and quarterly returns (if your turnover exceeds the £90,000 threshold)
- Corporation tax (for limited company contractors)
- National Insurance contributions for both employer and employee if operating through a limited company
- IR35 legislation, which determines whether HMRC views you as a genuine contractor or a “disguised employee”
Get any of these wrong, and the consequences range from penalty fines to back-tax bills. A specialist accountant for contractors in London understands these rules inside out—and keeps up with every HMRC update so you don’t have to.
How Does IR35 Affect London Contractors?
IR35 is arguably the single most important piece of legislation affecting UK contractors. Introduced to tackle tax avoidance, IR35 rules determine whether a contractor’s engagement resembles employment. If HMRC decides you fall “inside IR35,” you’ll be taxed similarly to an employee—significantly reducing your take-home pay.
Since the 2021 off-payroll working reforms, the responsibility for determining IR35 status has shifted to medium and large private-sector clients. That means your end-client now decides whether your contract sits inside or outside IR35—and getting that determination wrong can expose you to substantial tax liabilities.
A knowledgeable accountant will:
- Review your contracts for IR35 risk factors
- Advise on working practices that demonstrate genuine contractor status
- Help you respond to incorrect status determinations
- Structure your business to remain compliant at every stage
This isn’t an area to leave to chance or to a generalist accountant unfamiliar with contractor-specific rules.
What Services Does H2 Accounting Provide to Contractors?
H2 Accounting offers a comprehensive range of services designed to cover every aspect of a contractor’s financial life. Whether you’re a freelance IT consultant, a construction subcontractor, or an interim finance professional, these services are built around your needs.
Limited Company Accounting
Most contractors choose to operate through a limited company for tax efficiency. H2 Accounting handles everything from company incorporation to annual accounts, confirmation statements, and corporation tax returns—keeping you fully compliant with Companies House and HMRC requirements.
Self-Assessment Tax Returns
For sole traders and limited company directors drawing income through dividends and salary, annual self-assessment returns are mandatory. H2 Accounting prepares and files these accurately and on time, ensuring you claim every allowable expense.
Payroll and Dividend Planning
Structuring the right mix of salary and dividends is one of the most effective ways to legally reduce your tax bill. H2 Accounting works with you to optimise this balance based on your personal circumstances and current HMRC thresholds.
Bookkeeping and VAT Returns
Keeping clean financial records isn’t just good practice—it’s a legal requirement. H2 Accounting provides ongoing bookkeeping support and manages your quarterly VAT returns, including Flat Rate Scheme advice where applicable.
IR35 Contract Reviews
Before you sign any new contract, H2 Accounting can review it for IR35 exposure and recommend adjustments that protect your outside-IR35 status.
Why Choose H2 Accounting as Your Accountant for Contractors London?
There’s no shortage of accountants in London, but not all of them understand the contracting market. H2 Accounting’s founder, Abul Hasan, has conducted internal audits across multiple countries and worked with some of the most complex businesses in the world. That depth of experience translates directly into practical, commercially minded advice for contractors.
Here’s what sets H2 Accounting apart:
- ICAEW-qualified expertise — not just bookkeeping software and templates
- Contractor-specific knowledge — including IR35, off-payroll working rules, and limited company structures
- Personalised service — your finances are handled with confidentiality and genuine care
- Flexible, remote-friendly support — serving contractors across all of England, not just London
- Free initial consultation — so you can explore the right solution before committing
H2 Accounting is built on three core values: trust, balance, and quality. These aren’t just words on a website. They reflect a firm that understands finances are personal, and that the right accountant should reduce your stress—not add to it.
How Much Could You Save by Using a Contractor Accountant?
The short answer: more than the accountant costs you. A well-structured limited company with optimised salary and dividend payments, all allowable expenses claimed, and an efficient VAT scheme can save a contractor thousands of pounds per year compared to operating without specialist advice.
Beyond the tax savings, consider the time value. Hours spent deciphering HMRC guidance or completing incorrect returns are hours not spent winning contracts and building your business. Outsourcing your accounting to H2 Accounting means you get accurate, compliant financials—and your evenings back.
Frequently Asked Questions – Accountant for Contractors London
What does an Accountant for Contractors London typically do?
A contractor accountant handles self-assessment tax returns, limited company accounts, corporation tax, VAT returns, payroll, dividend planning, and IR35 compliance. The goal is to keep you fully compliant with HMRC while legally minimising your tax liability.
Do I need a limited company to use a contractor accountant?
No. H2 Accounting works with sole traders and limited company contractors alike. However, for higher-earning contractors, operating through a limited company is often more tax-efficient—your accountant can advise on the best structure for your situation.
How does IR35 affect my take-home pay as a contractor?
If your contract is deemed inside IR35, you’ll be taxed at employment rates on your income, removing the tax advantages of operating through a limited company. For many contractors, this can reduce take-home pay by 20–25%. A specialist contractor accountant can assess your IR35 status and advise on how to protect your position.
Can H2 Accounting help contractors outside London?
Yes. Although H2 Accounting is based in London, the firm provides contractor accounting services across the whole of England.

Is it worth paying for a specialist contractor accountant rather than using a generic firm?
For most contractors, yes. Contractor tax rules—particularly IR35, dividend planning, and allowable expenses—are specialist areas. A generalist accountant may not be across the latest legislation, which can result in missed savings or compliance errors that cost more than the accountant’s fee.
Take Control of Your Contractor Finances
Contracting offers freedom and earning potential that salaried roles rarely match. But that freedom comes with financial responsibilities that demand specialist knowledge. H2 Accounting provides London-based contractors and those across England with the expertise, structure, and personal attention needed to make the most of every pound earned.
