Plenty of people like the sound of being a company director. It sounds important – a title that says you’re in charge. But the truth is, being a director isn’t just for show. It comes with serious legal responsibilities, and if you don’t understand them, you could be heading for trouble
Being a director isn’t just about running the business. It’s about upholding your legal duties under the Companies Act, staying compliant with tax and employment law, and making decisions in the best interests of the company – not yourself. Some of these obligations catch new directors off guard, and if they’d known the full weight of what the role involves, they might have thought twice before stepping into it.
The list of responsibilities is long – but here’s 20 common ones to get you started:
1. You Must Always Act in the Best Interests of the Company
You’re legally obliged to put the company’s interests first – not your own. That means thinking long-term, avoiding conflicts of interest, and not using company assets for personal gain.
2. You and the Company Are Not the Same
Your company is a separate legal entity – a completely different ‘person’ in the eyes of the law. Its money is not your money. If you take funds from the business without proper documentation (e.g. salary, dividend, or loan), you could face unexpected tax charges.
3. You Must Keep Accurate Accounting Records
Every limited company must keep accurate records of all income, expenditure, assets, liabilities, and supporting documentation for at least six years.
4. You Must File Annual Accounts and Confirmation Statements
Statutory accounts are due nine months after year-end. Confirmation statements must be filed annually, even if nothing’s changed. Miss these and Companies House can strike off your company.
5. You Must Pay Corporation Tax and File CT600 Returns
Even if you make a loss or owe no tax, a return must still be submitted within 12 months of year-end. Payment is due within 9 months and 1 day.
6. Director’s Loan Accounts Must Be Properly Managed
Borrowing money from your company outside of payroll or dividends can lead to extra tax charges – 33.75% under s455 rules if the loan isn’t repaid in time.
7. You Must Register for PAYE and Run a Proper Payroll
If you pay yourself or anyone else wages, you must register with HMRC and submit payroll reports (RTI) every time you pay.
8. You Must Comply with Pension Auto-Enrolment
Even if you’re the only employee, you still have duties under the workplace pension rules. Non-compliance can lead to fines from The Pensions Regulator.
9. You Must Verify Your Identity with Companies House (From Nov 2025)
From November 2025, all directors and PSCs must verify their identity before any filings can be made. You’ll need a unique code and won’t be able to appoint directors, submit confirmation statements or change company details until this is done.
10. You Must File P11Ds for Benefits in Kind
If your company provides things like vehicles, health insurance, or gym memberships, these are taxable benefits and must be reported via P11D each year.
11. You Must Know Your VAT Rates
Not everything is 20%. Some window and door work (like new builds) may attract 0% or 5% VAT. Get this wrong and you could face large assessments.
12. You Must Only Claim VAT with a Valid Invoice
Knowing a supplier is VAT registered isn’t enough. You must hold a valid VAT invoice before reclaiming VAT – otherwise you’re not compliant.
13. CIS Must Be Operated Properly
If you pay subcontractors, you need to verify them, deduct tax if required, file monthly CIS returns, and provide deduction statements. This is often mishandled.
14. You Must Maintain Statutory Registers
You’re required to keep up-to-date registers of directors, shareholders, share transactions and Persons with Significant Control (PSC). These are often overlooked, but failing to maintain them is a breach of the Companies Act.
15. Dividends Must Be Declared Properly
You can’t just withdraw money and call it a dividend. Dividends must be backed by sufficient retained profits, board minutes, and dividend vouchers.
16. You Must Minute Key Decisions
Board meetings may be informal, but key decisions – like paying dividends, entering loans, or issuing shares – should be properly minuted and retained.
17. Personal Transactions Must Be Kept Separate
Your business bank account should be just that – business only. Personal transactions cause confusion, errors, and tax risk.
18. You Must Understand Your Insurance Obligations
Employers’ liability insurance is a legal requirement. Most directors also need public liability, professional indemnity, or tool/equipment cover – depending on their operations.
19. You Are Liable for Data Protection Compliance
If you hold any customer data, you’re likely required to register with the ICO and comply with GDPR. Fines for breaches can be steep.
20. Your PSC Register Must Be Accurate
Any changes in shareholding or controlling interests must be updated within 14 days. Keeping this accurate is not just best practice – from November 2025, Companies House will expect it to align with verified ID records.
This is Your Responsibility
You can’t rely on your accountant for everything – The Companies Act places ultimate responsibility on the directors – not your bookkeeper or accountant. If filings are late, or incorrect, it’s you HMRC and Companies House will pursue.
Final Thought
Being a director isn’t just about leading a business – it’s about understanding the rules that come with the role. These aren’t box-ticking exercises or red tape for the sake of it. They exist to protect your company, your customers, your staff, and ultimately, you. Get them wrong, and the consequences can be serious. Get them right, and you’ll run a stronger, safer, and more successful business.
