What are a director's responsibilities?

As a UK company director, you're legally responsible for running your company within the law and making sure the right information reaches Companies House and HMRC on time. Companies House is the register of UK companies, and HMRC collects tax.

Your responsibilities fall into two buckets. The first is your legal duties: How you're expected to act and make decisions. The second is your admin and filing duties: The records you keep and the returns you send. GOV.UK's overview for company directors sets out the basics.

These duties start the day you're appointed. They apply just as much when you run a small company and you're the only director, so it's worth knowing them early. If you're still setting up, this guide to starting a business covers the wider picture.

The 7 statutory duties under the Companies Act 2006

The law sets out seven general duties that every director must follow, in sections 171 to 177 of the Companies Act 2006. They describe how you're expected to behave, and they apply whether you run a corner shop or a growing agency.

Here's what each duty means, with a small business example:

• Act within your powers (section 171). Follow the company's rules in its articles of association, so you can't sign a deal the company hasn't authorised.
• Promote the success of the company (section 172). Make decisions that help the business succeed, weighing the long-term impact on staff, suppliers, customers and your reputation.
• Exercise independent judgment (section 173). Form your own view on decisions rather than simply doing what an investor or co-founder tells you.
• Exercise reasonable care, skill and diligence (section 174). Run the company as carefully as a sensible person would, using any extra expertise you happen to have.
• Avoid conflicts of interest (section 175). Steer clear of situations where your personal interests clash with the company's, such as a side business that sells to it.
• Don't accept benefits from third parties (section 176). Turn down gifts or perks offered because of your role if they could sway your decisions, like a supplier's kickback.
• Declare an interest in a proposed transaction (section 177). Tell your fellow directors before the company enters a deal you'd personally gain from, such as renting it your own premises.

The full legal wording for each duty sits in the Companies Act 2006 on legislation.gov.uk.

Your admin and filing responsibilities as a director

Alongside your legal duties, you're responsible for keeping proper records and filing on time with Companies House and HMRC. Missing a deadline can lead to penalties, so it helps to know what's expected of you as part of running a limited company.

Your main admin and filing responsibilities are to:

• Keep accounting and company records. Hold on to records of what the company earns, spends and owns, plus registers of directors and shareholders.
• Prepare and file annual accounts. Send your company accounts to Companies House each year, showing how the business performed.
• File a confirmation statement. Confirm your company details are up to date with Companies House at least once a year.
• Complete a Company Tax Return and pay Corporation Tax. Report your profits to HMRC and pay the tax due; this guide explains how Corporation Tax works.
• Register for and file VAT if you cross the threshold. Once your turnover passes the threshold you must register for VAT and file returns digitally under Making Tax Digital, or MTD.
• Tell Companies House about changes. Report a new registered office, a change of director, or a new person with significant control (PSC) who owns or controls more than 25%.
• Verify your identity with Companies House. Identity verification (IDV) became a legal requirement on 18 November 2025 and is being introduced in stages, so your deadline depends on your role and dates.

A PSC is anyone who owns or controls a large share of your company, and IDV simply proves you are who you say you are. You can check the process for verifying your identity for Companies House before your deadline.

Director liability: When are you personally responsible?

A limited company is legally separate from you, so it usually protects your personal money if the business runs into trouble. That protection isn't absolute, though, and a few situations can make you personally responsible.

You can be held personally liable in cases such as:

• Breaching your statutory duties: If you break one of the seven duties above and the company or its shareholders lose out, you can be held responsible.
• Wrongful or fraudulent trading: If you keep trading when you know the company can't pay its debts, a court can make you personally liable.
• Signing a personal guarantee: If you personally guarantee a loan or lease and the company can't pay, the lender can come to you.
• Paying unlawful dividends: If you pay dividends the company can't afford from its profits, you may have to repay them.
• Unpaid tax and health and safety breaches: HMRC and regulators can pursue you personally for certain unpaid taxes or serious safety failings.

For most directors who act honestly and keep good records, these situations rarely come up. In serious cases, though, a court can disqualify someone from acting as a director.

Tips for staying on top of your responsibilities as a first-time director

Staying compliant is mostly about good habits and a reliable calendar. A few simple routines make it much easier to meet your duties without last-minute stress.

Here are five practical steps to build into your first year:

• Note your key filing dates. Put your annual accounts, confirmation statement and Corporation Tax deadlines in a calendar, and set reminders a few weeks ahead.
• Keep business and personal finances separate. Use a dedicated business bank account so company money never mixes with your own.
• Keep clear records as you go. Log income and expenses regularly instead of scrambling at year-end, and store receipts safely.
• Get advice before big decisions. Talk to an accountant before you pay a dividend, take on a loan, hire staff or sign a large contract.
• Use software to automate reminders and records. Cloud accounting software can track deadlines and keep everything tidy in one place.

FAQs on directors' responsibilities

Here are quick answers to some common questions first-time directors ask.

What are the 7 duties of a director?

They're the seven general duties in the Companies Act 2006: Act within your powers, promote the company's success, exercise independent judgment and reasonable care, avoid conflicts, refuse third-party benefits, and declare interests. They apply equally to every director, whatever the company's size.

What is a company director legally responsible for?

You're responsible for running the company within the law and making sure accurate information reaches Companies House and HMRC on time. That covers your day-to-day decisions and the paperwork behind them.

Can a director be personally liable for company debts?

Usually no, because a limited company is legally separate from you. You can become liable if you sign a personal guarantee, trade while insolvent, or break your legal duties.

Can a director just walk away from a company?

No. You need to formally resign, tell Companies House, and deal with the company's affairs properly; simply stopping doesn't cancel your duties or the company's debts.

Do the same duties apply if you're the only director?

Yes. A sole director carries all seven statutory duties and every filing obligation, with no one to share the load, so reminders and good habits matter even more.
