Navigating tax compliance can be challenging for UK business owners and company directors. Many struggle with knowing which HMRC system to use, when to register and how to stay compliant. Getting this wrong can result in missed deadlines, penalties and unnecessary administrative burdens that take time away from running your business.
The confusion often stems from HMRC’s two separate digital platforms. The Personal Tax Account (PTA) manages your individual tax affairs, whilst the Business Tax Account (BTA) handles all business tax obligations. Each serves different purposes and caters to different users. If you’re a sole trader, you might need both. If you’re a limited company director, you’ll interact with both systems but in different ways.
This guide covers:
- The purpose and functions of each account type
- Core differences in taxes managed and user access
- Which account you need based on your business structure
- Practical setup steps and compliance requirements
- Common scenarios for sole traders and limited company directors
What is a Personal Tax Account?
The HMRC Personal Tax Account is your online portal for managing individual tax affairs. It’s designed for anyone who pays tax as a private citizen, whether you’re employed, self-employed or receiving a pension.
Through your Personal Tax Account, you can view your tax code, check your National Insurance record, forecast your State Pension and update personal details. The PTA gives you a complete picture of your personal financial relationship with HMRC, accessible 24/7 through your Government Gateway login.
What You Can Manage Through Your Personal Tax Account?
- View your Income Tax estimate and tax code
- Check your National Insurance contributions record
- Track your State Pension forecast
- Manage Self-Assessment (if you’re self-employed as an individual)
- Claim Marriage Allowance or update Child Benefit details
- Report changes to personal circumstances such as address or name
The system focuses purely on you as an individual taxpayer, not on any business entity you might operate.
What is a Business Tax Account?
The Business Tax Account is HMRC’s hub for managing all business tax obligations. Whether you run a sole trader operation, a limited company or a partnership, the BTA gives you access to over 40 different business taxes and schemes.
This is where you register for VAT, set up PAYE for employers when you hire staff, file Corporation Tax returns and manage other business-specific compliance requirements. The platform allows you to check deadlines, view payment history and give access to team members or your accountant.
What You Can Manage Through Your Business Tax Account?
- Register for business taxes (VAT, PAYE, Corporation Tax)
- File business tax returns and submit payments
- View payment deadlines and transaction history
- Manage multiple business taxes in one place
- Grant access to your accountant or team members
- Track business tax obligations and compliance status
Unlike the PTA, this system is built around the business entity itself, not the individual behind it.
Key Differences Between Personal Tax Account and Business Tax Account
Understanding the difference between personal and business tax accounts comes down to recognising what each system manages and who it’s designed for. The following table shows the main distinctions.
| Feature | Personal Tax Account | Business Tax Account |
|---|---|---|
| User Type | Individuals (employees, self-employed, pensioners) | Business entities (sole traders, limited companies, partnerships) |
| Primary Purpose | Manage personal Income Tax and National Insurance | Manage business taxes and regulatory compliance |
| Taxes Covered | Income Tax, Self-Assessment (personal), NI contributions, State Pension | VAT, PAYE for employers, Corporation Tax, Self-Assessment (business) |
| Income Reported | Salary, dividends, rental income, foreign income | Business profits, expenses, capital allowances |
| Access Control | Individual access, can authorise an agent | Administrator can grant team or agent access |
| Tax Rates Applied | Personal income tax bands (20%, 40%, 45%) | Corporation Tax rates or business-specific rates |
This distinction matters because using the wrong account or failing to use both when required can result in missed deadlines, incorrect filings and HMRC penalties.
Who Needs Which Account?
Your business structure determines which HMRC online services you’ll need to access. The following sections explain requirements for different business types.
Individuals and Employees
If you’re employed and receive a salary through PAYE, you’ll use the Personal Tax Account to check your tax code, view your Income Tax estimate and manage your National Insurance record. You don’t need a Business Tax Account unless you have business income.
Sole Traders
Sole traders occupy a unique position. You are both an individual taxpayer and a business operator. You’ll need to access both accounts:
- Personal Tax Account: To view your NI record and manage personal tax affairs
- Business Tax Account: To register for Self-Assessment, file your Self-Assessment tax return and manage VAT (if your turnover exceeds £90,000)
You use the same Government Gateway login to access both systems. The accounts work together to give you a complete view of your tax position.
Limited Company Directors
As a limited company director, you interact with both systems but in different ways:
- Personal Tax Account: For your personal Income Tax on salary and dividends you receive from the company
- Business Tax Account: For the company’s Corporation Tax, PAYE for any employees and VAT registration
Your limited company is a separate legal entity, so its Corporation Tax account sits entirely within the BTA. Your personal earnings from the company flow through your PTA.
Partnerships
Partnerships file their own returns through the Business Tax Account, but individual partners report their share of profits through their Personal Tax Accounts. This split ensures both business and personal tax compliance.
Understanding Business Tax Obligations in 2026
Small business tax filing requirements continue to evolve with HMRC’s digital transformation. As of 2026, Making Tax Digital (MTD) requires businesses to keep digital records and submit returns through compatible software.
Core Business Taxes to Manage
VAT Registration: Required when your taxable turnover exceeds £90,000. According to HMRC guidance, the VAT threshold remains at £90,000 for 2026. You manage VAT through the BTA, submitting returns quarterly or monthly depending on your scheme.
PAYE for Employers: If you employ staff, you must register for PAYE and report payroll information in real time through the BTA.
Corporation Tax: Limited companies pay Corporation Tax on profits. According to HMRC’s Corporation Tax rates guidance, the rates for 2026 are:
- 19% for profits up to £50,000 (small profits rate)
- 25% for profits over £250,000 (main rate)
- Marginal relief applies for profits between £50,000 and £250,000
Self-Assessment (Business): Sole traders and partners file Self-Assessment returns reporting business income and expenses. This happens through the BTA but connects to your personal tax calculation.
Setting Up Your Accounts: Practical Steps
Getting started with HMRC digital tax accounts requires a Government Gateway login. This single credential gives you access to both the PTA and BTA as needed.

Common Scenarios and Solutions
The following scenarios illustrate how different business structures use these accounts.
Scenario 1: Starting as a Sole Trader
When you begin self-employment, register for Self-Assessment through the Business Tax Account before 5 October following the end of the tax year in which you started trading. You’ll file your first return by the following 31 January.
Continue using your Personal Tax Account for your NI record and personal tax code, especially if you have employment income alongside self-employment.
Scenario 2: Moving from Sole Trader to Limited Company
When you incorporate, you’ll need to:
- Close your Self-Assessment for business income (sole trading ceases)
- Register the new company for Corporation Tax within three months
- Set up a Corporation Tax account in the BTA
- Continue using your PTA for personal Income Tax on salary and dividends from the company
This transition is a critical point where many business owners need professional guidance from accountants.
Scenario 3: Managing Multiple Businesses
If you operate several businesses or companies, you can manage all of them through a single Government Gateway login. Each business entity gets its own section within the Business Tax Account, allowing you to switch between them easily.
Conclusion
The Personal Tax Account and Business Tax Account serve distinct purposes in managing your tax obligations. Understanding the difference between personal and business tax accounts is essential for staying compliant and avoiding penalties.
For sole traders, using both accounts correctly ensures you capture both your personal and business tax responsibilities. Limited company directors need both systems to manage personal Income Tax separately from Corporation Tax obligations.
