Different kinds of self-employed businesses

A self-employed individual may be a freelancer or a consultant, an artisan or a member of other business structures providing a diversity of services and products independently.

Limited liability partnerships (LLP)

Limited Liability Partnerships (LLPs) combine the flexibility of a partnership with limited liability protection for its members.

In LLPs, partners are not personally liable for the company’s debts or liabilities, shielding their assets. This structure is popular among professional firms like law and accounting practices, offering a balance between partnership collaboration and individual financial security.

Private Limited Company (Ltd)

A Private Limited Company (Ltd) is a business entity with limited liability, protecting owners’ assets. It requires at least one director and shareholder, offering flexibility in operations and ownership.

Ltd companies can’t publicly trade shares and have restricted shareholder transfers, promoting stability. This structure fosters private investments, allowing businesses to expand and innovate while safeguarding stakeholders’ interests.

Why do you need to register as self-employed?

Registering as self-employed is essential for legal and financial reasons. It formalises your business, making you accountable for taxes and ensuring compliance with regulations. It provides access to tax benefits, allowing you to deduct business expenses, and reducing the overall tax burden.

In addition to enhancing credibility, registration also promotes client and partner confidence. Furthermore, it provides avenues for business loans and grants, which facilitates growth opportunities for the organisation.

In general, being a self-employed professional or business owner establishes trust, financial transparency, and legal compliance.

When should I register my self-employment?

To avoid legal complications, it is important to register your self-employment as soon as possible. You are required to register your own business within a certain period after starting it, frequently within a few months of commencing operations or earning income.

An accurate registration will ensure that you comply with tax regulations and business laws, preventing fines and penalties from being imposed. Besides enabling you to access tax benefits, it also contributes to the establishment of a strong financial foundation, and it facilitates the smooth operation of your business within the legal framework.

What’s the difference between registering as self-employed and being PAYE?

Self-employment means that you work for yourself and are responsible for your taxes. To file your tax returns as a sole trader, you will need to file a self-assessment tax return. When you are PAYE (Pay As You Earn), your employer deducts taxes directly from your salary so you don’t have to pay tax actively.

In contrast to PAYE employees who have their taxes deducted automatically from their paychecks, self-employed individuals have more control over their work as well as managing their taxes and expenses independently by filling out a self-assessment tax bill each tax year.

What happens after I’ve registered as self-employed?

Upon registering as self-employed, you will receive a Unique Taxpayer Reference (UTR) and can file your self-assessment tax return. Ensure that you keep meticulous records of your taxable income, expenses, business debts and receipts.

You are personally responsible as a sole trader to pay income tax and National Insurance contributions. The HM Revenue and Customs (HMRC) will provide deadlines for the filing of your tax return and the payment of taxes.

It is important to stay organised so that you can meet your obligations and avoid penalties within each tax year.

How do I stop being self-employed?

To cease being a self-employed individual, you must submit a final tax return to HM Revenue and Customs (HMRC).

You should report your total income, expenses, and any capital allowances. Make arrangements to settle any outstanding taxes and National Insurance contributions. Record keeping of your tax return should be maintained for a period of five years at a minimum.

As soon as the process is completed, you will no longer be considered self-employed for tax purposes like your tax return.

Do you need an accountant?

Your financial complexity and expertise will determine whether you require the services of an accountant.

In addition to tax planning and bookkeeping, accountants can help ensure compliance with tax laws and your assessment tax return. For businesses with intricate financial matters, they can save time and provide expertise.

In the beginning, small businesses might manage without an accountant, but as operations grow, the professional guidance of an accountant becomes increasingly valuable (for instance while doing your tax return).

Do I need a business bank account for my own business?

For a financial organisation, it is essential to have a dedicated business bank account. In addition, it simplifies tax filing and enhances professionalism by separating personal and business assets and finances.

The system also assists in tracking business expenses, managing cash flow, and accessing business-specific services. Keeping accurate financial records is not legally required for sole traders, but it is highly recommended to foster credibility with clients and partners by maintaining accurate records.

What insurance do self-employed people need?

The self-employed often require multiple types of insurance to protect their businesses and minimise risks.

Insurances commonly offered include public liability insurance, which covers legal costs incurred in cases of injury or property damage, professional indemnity insurance, which protects against legal claims arising from professional advice or services, and business equipment insurance, which protects tools and equipment against legal claims.

Furthermore, income protection insurance provides financial security to self-employed individuals in case they are unable to work due to illness or injury. Self-employed individuals need these insurance policies to ensure business continuity as well as financial stability. They will give them peace of mind while managing their businesses.

A sole trader or a limited liability partnership are both types of self-employed businesses with their advantages and challenges. The key to compliance and avoiding penalties is timely registration. For a smooth operation, it is essential to maintain accurate records, whether for taxes or business expenses.

As your business grows, engaging professionals such as accountants can be extremely beneficial. The Internet, government websites, and business advisory services provide self-employed individuals with a wealth of information to assist them in becoming successful and sustainable entrepreneurs.
