Quick Answer: What are the disadvantages of a private limited company?
The 10 main disadvantages of a private limited company in the UK are:
- Greater administrative burden, including filing with Companies House
- Public disclosure of company accounts and director details
- Higher set-up and ongoing accounting costs
- Corporation Tax liability (currently 19%–25% set by HM Revenue & Customs)
- Limited access to capital compared to public companies
- Ongoing legal and regulatory compliance requirements
- Personal guarantee risks for directors
- Reduced mortgage credibility for director-shareholders
- IR35 off-payroll working risks for contractors
- Potential for shareholder disputes
Most of these drawbacks are manageable with the right limited company accountant, but they are real costs to consider before choosing this structure.
A private limited company, often called a Ltd company or a company limited by shares, is one of the most common business structures in the UK. It separates your personal finances from the business, gives you more tax planning options, and presents a more professional image than a sole trader.
But it is not the right fit for everyone. Before you register a company with Companies House, you need to understand what a private limited company actually costs in time, cost, and flexibility.
This guide breaks down the 10 genuine disadvantages of a private limited company in clear, simple terms, using real figures from the 2025/26 tax year, so you can make a well-informed decision.
If you already run a limited company and want to reduce the admin burden, GoForma’s MAAT-qualified limited company accountants can help you stay compliant while keeping things simple.
What is a Private Limited Company?
A private limited company is a separate legal entity incorporated atCompanies House under the Companies Act 2006. It is owned by shareholders (who hold shares) and managed by at least one director.
The key feature is limited liability. This means the company is responsible for its own debts and legal obligations, not you personally. If the business fails, your personal assets like your home, savings, and car are usually protected, unless you have signed a personal guarantee.
A private limited company cannot sell shares to the public. That is the difference between a Ltd company and a public limited company (PLC). Most UK small businesses and contractors operate as Ltd companies for this reason.
Now, let’s look at the disadvantages of this structure clearly and honestly.
10 Disadvantages of a Private Limited Company
1. Greater Administrative Burden
When you operate as a sole trader, admin is fairly light. You track income and expenses and file a Self Assessment once a year.
A private limited company is very different. From the moment you incorporate with Companies House, you take on ongoing legal and tax obligations every year, even if the company makes no profit or is dormant.
What the admin workload looks like
- Annual accounts filed with Companies House within 9 months of year end
- Corporation Tax return (CT600) filed with HMRC within 12 months
- Corporation Tax paid within 9 months and 1 day of year end
- Confirmation Statement filed annually (£34 online / £62 by post)
- Payroll RTI submissions to HMRC every time you pay yourself or staff
- VAT returns every quarter if turnover exceeds £90,000
- Director Self Assessment due by 31 January each year
- Board meeting records kept for key decisions
Miss a deadline and penalties apply automatically. For example, a late Corporation Tax return starts at £100, rises to £200 after three months, and with a further 10% tax-geared penalty after 18months.
For most directors, managing all of this alone is not realistic. That is why many hire an accountant, which adds to the overall cost of running a limited company.
2. Public Disclosure of Financial and Director Information
One of the most overlooked disadvantages of a private limited company is partly public transparency. Companies House is a public register and the moment you register with Companies House, key details about your business become publicly available.
Your competitors, potential clients, journalists, or curious members of the public can search your company and view:
- Annual accounts, including turnover, profit, and liabilities
- Full names of directors
- Month and year of birth of directors
- Service address for each director
- Registered office address
- Share structure and major shareholders (Persons of Significant Control)
For many founders, this level of visibility feels uncomfortable, especially when competitors can access financial information. A sole trader does not face this requirement.
Even if you file as a micro-entity with simplified accounts, your core details still appear on the public record. Even micro-companies that benefit from reduced filing requirements (a balance sheet only, no profit and loss account) still put their name, address, and director details on the public record.
You can reduce some exposure by using a registered office or virtual address instead of your home address. At GoForma, most of our limited company accounting clients can use our registered office address in London for this purpose. However, your company accounts and director details will always remain publicly accessible under UK company law.
3. Higher Set-Up and Ongoing Accounting Costs
Running a private limited company costs more than operating as a sole trader. These are real, ongoing costs you should factor in before you register with Companies House.
Formation costs
- Companies House incorporation fee: £100 (online) or £124 (by post)
- Confirmation Statement: £50 per year (online) and £110 by post
- Registered office address (if using a virtual office): typically £35 to £150 per year
Ongoing accountancy costs
This is where the difference becomes significant.
- Sole trader: typically £200 to £500 per year for a basic Self Assessment
- Limited company:
- £800 to £1,500 per year for a basic package (accounts, CT600, confirmation statement, director tax return)
- £1,500 to £2,500 per year with VAT and payroll included
- £2,500+ per year for more complex setups (multiple directors or employees)
You can reduce costs by working with a specialist online accountant rather than a traditional high street firm. GoForma’s limited company packages start from £49 per month and cover everything from incorporation to annual accounts and tax filings.
Even with cost savings, the gap between sole trader and limited company expenses is real. It is worth comparing your take-home pay before deciding to incorporate.
4. Corporation Tax on Company Profits
A sole trader pays Income Tax directly on profits. A limited company works differently. The company first pays Corporation Tax on its profits, and then you pay Income Tax and National Insurance on your salary, plus Dividend Tax on any dividends you take.
The Corporation Tax rates in the2025/26 tax year are:
This creates an extra layer of taxation that does not apply to sole traders. In practice, the tax efficiency of a limited company usually starts to work when profits reach around £30,000 to £35,000 per year and you structure salary and dividends tax-efficiently. Below that level, the benefit often disappears once you include higher accountancy costs.
Cash flow planning also becomes more important. HMRC requires Corporation Tax to be paid nine months and one day after your year end. Many new directors run into trouble by spending profits during the year and then facing a large tax bill later. An accountant for limited company can help you set aside the right amount each month.
5. Restricted Access to Capital Compared to a Public Company
Private limited companies cannot offer shares to the public or list on a stock exchange. This limits your ability to raise large-scale funding compared to a public limited company (PLC). If you plan to raise significant capital through an IPO, you would need to convert your business structure to PLC, which is a complex and costly process.
In reality, most small businesses never need public capital markets, so this disadvantage rarely applies to contractors, consultants, and micro-businesses. Where it matters is for growth-focused startups aiming to raise large amounts of investment. Even then, private companies can still access funding through angel investors, venture capital, and schemes like EIS and SEIS.
A more practical limitation is how shares are transferred. You cannot freely sell shares to anyone. You must follow the rules in your Articles of Association and any shareholders’ agreement. This can slow down investment and make it harder for shareholders to exit quickly.
6. Legal and Regulatory Compliance Requirements
A private limited company operates within a strict legal framework set by the Companies Act 2006 and rules from HMRC. As a director, your responsibilities go beyond running the business day to day.
You are personally responsible for:
- Acting within your powers under the Articles of Association
- Promoting the success of the company for its shareholders
- Using independent judgement and avoiding conflicts of interest
- Declaring any personal interest in transactions
- Filing all required documents on time with Companies House and HMRC
- Keeping accurate accounting records for at least six years
If you breach these duties, you can face personal liability even with limited liability protection. For example, under the Insolvency Act 1986, directors can be held personally responsible if they continue trading while the company is insolvent.
If you employ staff, your responsibilities increase further. You must handle employer National Insurance, workplace pension auto-enrolment, IR35 assessments, and wider employment law duties. Each adds more time, cost, and complexity to running your company.
7. Personal Guarantee Risks for Directors
Limited liability is one of the main reasons people set up a company, but in practice many directors reduce that protection by signing personal guarantees.
Banks, landlords, and suppliers often ask directors of small companies to personally guarantee loans, leases, or credit agreements. When you sign, you agree to repay the debt from your own assets if the company cannot. In those cases, limited liability does not apply to those specific obligations.
Personal guarantees are common when:
- Applying for a business loan or overdraft
- Signing a commercial property lease
- Taking trade credit from suppliers
- Using asset finance or hire purchase
If the company faces financial difficulties or bankruptcy, creditors may argue that the shareholders did not maintain proper separation between personal and company finances, making them personally liable for the company's debts.
The practical takeaway here is limited liability still offers real protection in many situations, including general creditor claims and most liabilities owed to HMRC. But if your business relies heavily on debt finance or significant lease commitments, you may already be personally exposed.
8. Difficulty Getting a Mortgage as a Director-Shareholder
This is a real and often underestimated disadvantage that affects many UK limited company directors every year.
Mortgage lenders assess directors differently from employees. If you take a small salary and most of your income as dividends, lenders usually base affordability on:
- Your PAYE salary plus dividends actually taken (not total company profit)
- Two to three years of company accounts
- Your personal tax returns (SA302s) for the same period
If your company retains profits instead of paying them out, those profits are often ignored in affordability checks. This means you can appear to earn less than you actually do, which can reduce the size of mortgage you are offered.
Some specialist lenders will assess income based on company profits rather than salary and dividends, but these deals often come with higher interest rates and require an experienced broker.
In simple terms, running a tax-efficient limited company can make borrowing harder. It is a practical financial trade-off that many directors only discover when they apply for a mortgage.
9. IR35 and Off-Payroll Working Rules for Contractors
This disadvantage mainly affects contractors who work through a limited company for public sector clients or medium to large private businesses. If that applies to you, IR35 is one of the biggest risks you face as a limited company director.
The off-payroll working rules, known as IR35, determine whether HMRC views your engagement as genuinely self-employed or as a disguised employment relationship. If your client (or HMRC) determines you are ‘inside IR35’, the consequences are serious:
- The fee-payer deducts Income Tax and National Insurance before you are paid
- You lose the tax benefits of the salary and dividends structure
- You pay tax like an employee but do not receive employee benefits such as sick pay or holiday pay
- HMRC can investigate up to six years of past contracts
Since April 2021, responsibility for determining IR35 status moved to the end client for medium and large organisations. Many large organizations responded with blanket ‘inside IR35’ determinations as a precaution, which pushed some contractors to stop using limited companies altogether.
If you are genuinely outside IR35, a limited company can still be very tax-efficient. But the risk of being reclassified remains a real and ongoing downside that sole traders do not face.
GoForma tip for contractors
Our contractor accountants help contractors review their IR35 status, structure their contracts correctly, and keep CEST-compliant records. If HMRC challenges your status, good documentation is your best defence.
10. Potential for Shareholder Disputes
If you set up a limited company with other people, you share ownership based on your shareholdings. That works well when everyone agrees. It becomes a genuine legal andfinancial problem when shareholders disagree.
Without a Shareholders’ Agreement, disputes fall back on the default rules in the Companies Act 2006 and your Articles of Association. These do not always lead to fair or practical outcomes, especially when:
- A director wants to exit but cannot agree on a share price
- Shareholders disagree on dividends or reinvestment
- A director is removed but still owns shares
- The business grows and minority shareholders feel sidelined
Disputes can quickly become expensive and time-consuming. In serious cases, they end up in court. Even when they do not, they drain time, money, and focus from the business.
The fix is simple. Put a Shareholders’ Agreement in place before you incorporate with others. It usually costs a few hundred pounds, but resolving disputes without one can cost tens of thousands.
Private Limited Company vs Sole Trader
Let's compare the two most common UK business structures across the factors that matter most to small business owners and contractors.
Is a Private Limited Company Still Worth it?
Yes, for the right person in the right situation. The disadvantages above are real, but so are the advantages. The real question is whether the benefits outweigh the drawbacks for your specific setup.
A limited company usually makes sense if:
- Your annual profits are above £30,000 and you want to use salary and dividends for tax efficiency
- You want limited liability protection because your work carries risk
- You plan to hire staff or win contracts that require a Ltd structure
- You want to grow, attract investors, or sell the business later
- You work as a contractor and your contracts fall outside IR35
A limited company may not be right if:
- Your profits are below £25,000 and the tax savings do not cover the extra costs
- You want a simple setup with minimal admin and have no plans to employ people or raise investment
- You mostly work inside IR35 or your status is uncertain
- You are still testing your business idea

FAQs
What are the main disadvantages of a private limited company in the UK?
The key drawbacks include higher admin (Companies House filings, CT600, confirmation statement), public visibility of accounts and director details, higher accounting costs (£800–£2,500+ per year), corporation tax at 19–25%, limits on raising public capital, legal duties under the Companies Act 2006, personal guarantee risks, mortgage challenges for directors, IR35 risks for contractors, and possible shareholder disputes.
Is it expensive to run a private limited company?
Yes, it costs more than being a sole trader. The Companies House confirmation statement is £50 per year (online). Accountancy fees usually range from £800 to £2,500 per year depending on services like VAT and payroll. A registered office service can add £50–£150 per year. In total, expect around £1,000–£3,000 more per year than a sole trader setup.
Do private limited company directors pay more tax?
Not necessarily more, but differently. The company pays corporation tax at 19–25%, then you pay tax on salary and dividends. With the right structure, many directors pay less tax than sole traders at the same profit level. The tipping point is usually around £30,000–£35,000 profit.
What is the biggest disadvantage of a private limited company?
It depends on your situation. For many, it is the extra admin and cost. For contractors, IR35 risk is often the main issue. For directors planning to buy property, mortgage affordability can be the biggest hurdle. There is no single answer.
Does a private limited company have to publish its accounts?
Yes. All UK limited companies must file accounts with Companies House, where they are publicly available. Small companies can file simplified accounts, but some financial information is always visible.
Can I lose my personal assets if my company has debts?
Usually no. Limited liability means the company is responsible for its debts. Your personal assets are protected. Exceptions include personal guarantees, wrongful trading, or fraud. In reality, many small business owners sign personal guarantees, which reduces that protection for specific debts.
What happens if I miss a Companies House deadline?
Late filing penalties apply automatically. For accounts, penalties start at £150 and can rise to £1,500. Repeated late filing doubles the penalty. HMRC also charges penalties for late corporation tax returns, starting at £100 and increasing over time.
Is a limited company better than a sole trader?
It depends on your goals. A limited company offers tax efficiency (above ~£30,000 profit), limited liability, and a stronger business image. A sole trader setup is simpler, cheaper, and often better for mortgages. Many people start as sole traders and incorporate later.
Can a private limited company have just one director?
Yes. One person can be both the sole director and shareholder. This is very common for contractors and freelancers.
What is IR35 and how does it affect my limited company?
IR35 is a set of rules that decide whether you are truly self-employed or effectively an employee. If you fall inside IR35, tax and National Insurance are deducted before you are paid, removing most of the tax benefits of a limited company. IR35 does not apply to sole traders.
