Sign up for online services

HMRC online services allow individuals, businesses and agents to manage tax matters securely over the internet. Using an HMRC online account, you can send information such as self-assessment tax returns or VAT registration applications, view important records like your business or personal tax account and make payments online.

To access these services, you will need to ensure you have set up an account with HMRC. If you do not already have sign-in details, you can easily create them. HMRC provides three types of online services accounts: individual accounts, organisation accounts and accounts for agents.

An individual account lets you set up a Personal Tax Account where you can complete tasks such as checking your Income Tax estimate and tax code, updating personal details and claiming tax refunds. You can also register for self-assessment if you need to report income from sources such as property or investments. The same sign-in details can be used for both services.

Organisation accounts are for businesses and trusts. A business tax account allows sole traders, partnerships and limited companies to register for self-assessment (if self-employed), VAT, PAYE and Corporation Tax, depending on what is required.

A number of HMRC services use a separate sign-in process, including excise, import and export services, childcare accounts and for reporting Capital Gains Tax on UK property.

I'm Aitch, the Founder and CEO of CIGMA Accounting Ltd. As a Chartered Management Accountant and as a CIMA member, I've spent more than 16 years helping businesses, entrepreneurs, landlords, and individuals with tax planning, accounting, and HMRC compliance. As a chartered accountant in London, I'm passionate about making complex tax matters easier to understand and helping clients make confident financial decisions. Over the years, I've advised start-ups, SMEs, established companies, and high-net-worth individuals across a wide range of tax and accounting matters. My expertise includes Corporation Tax, Self-Assessment, Capital Gains Tax, Inheritance Tax planning, R&D tax relief, capital allowances, international tax, and resolving complex HMRC compliance issues. Whether clients need a business accountant, tax accountant, or strategic tax advisor, my focus is always on delivering practical advice that creates long-term value. One of my specialist areas is Making Tax Digital (MTD). I've worked extensively with businesses preparing HMRC's digital reporting requirements, helping them move to cloud accounting, improve financial processes, and adopt technology that makes compliance more efficient. I regularly speak at Making Tax Digital roadshows, industry events, and educational sessions in collaboration with Zoho Books, sharing practical insights into digital accounting, tax legislation, and the future of the profession. Many business owners looking for the best accounting firm in London are not simply searching for an accountant they're looking for trusted advice, responsive support, and long-term value. That's the approach I've taken in building CIGMA Accounting. My team and I work closely with businesses across London and the UK, providing accounting services, tax advisory, bookkeeping, payroll, VAT, company accounts, and strategic tax planning tailored to each client's goals. Through this website, I share practical guidance on UK taxation, Making Tax Digital, HMRC updates, Corporation Tax, Self-Assessment, and business finance. My aim is to provide reliable, straightforward information that helps business owners understand changing regulations, reduce compliance risks, and make informed financial decisions with confidence.
