Starting a business is exciting, but some founders can get caught up in the moment and forget important tasks. While legal and admin duties may not seem as interesting as launching a brand, they’re essential when forming a company.
Getting things right from the start can help you avoid costly mistakes later. Because of this, many founders use company formation services to simplify the set-up process. In this article, 1st Formations will run through five essential steps to help you start your business – with or without external support.
1. Choose the right business structure
One of the first decisions when setting up a company is choosing an appropriate legal structure. The structure you choose affects how you pay tax and your administrative responsibilities. It’s therefore important to assess your options carefully before deciding.
In the UK, the three main business structures you should be aware of as a new founder are:
- Sole trader – If you’re working by yourself, this is the simplest structure. It tends to suit those who offer freelance services, tradespeople, and small-scale retailers. However, as a sole trader, you’re personally liable for any business-related debts. For example, if you buy and sell goods as a sole trader, you take on the cost of your stock. So, if you’re unable to sell items, you’ll take on the loss personally.
- Partnership – This is similar to a sole trader structure but shared between partners. For example, two dog walkers sharing the workload may choose to form a partnership.
- Limited company – This establishes a business as a separate legal entity from its owners. The company is responsible for its debts, rather than the founder. This structure generally protects owners’ personal assets from claims made against the business. To operate as a limited company, you’ll need to register with Companies House and meet ongoing reporting requirements.
Because every business operates differently, certain structures will suit some types of businesses more than others.
Founders who want to create a clear separation between personal and business finances and avoid personal liability may want to consider registering as a limited company. Freelancers who have a simple set-up may prefer to reduce their admin responsibilities and operate as a sole trader instead.
When deciding on a structure, consider both your current needs and your long-term plans. If you’re planning to scale, you may find it easier to register as a limited company from the start even if you could initially work as a sole trader. If you do this, you’ll need to manage additional admin or use external support.
2. Register your business with Companies House (if necessary)
If you choose to establish your business as a limited company, you’ll need to register it with Companies House. You should do this before trading, although it is possible to convert an existing sole trader business to a limited company.
To register your company, you need to choose a unique name. It will need to comply with naming rules, such as having no offensive terms and the correct use of ‘Limited’ or ‘Ltd’.
You’ll also need to provide Companies House with a registered office address. This must be a physical UK address where official correspondence is sent. It will be publicly displayed on Companies House. If you don’t have an appropriate address, you can pay for a business address service and register your business at a shared location.
You’ll need to appoint at least one director who is legally responsible for running the company, managing finances, and filing accounts. This can be you. Optionally, you can also assign a company secretary who can help with compliance and governance. You’ll need to inform Companies House of the appointment of any directors and your company secretary. You’ll also need to issue at least one share and identify the company’s shareholders, who are the business’s legal owners.
To incorporate a limited company, you’ll also need to have a document called the Memorandum of Association (MoA). The MoA outlines the founders’ intent to form a company. Alongside this, you’ll need to have articles of association, which outline the rules of how the company is run. Many entrepreneurs find these legal requirements difficult to navigate, which is why some use formation agents to help simplify the registration process and reduce filing errors.
3. Organise your finances and register for taxes
You should aim to organise your finances early in the set-up process. This will ensure compliance with HMRC and help you maintain clear records.
If you want to establish your business as a limited company, you’ll need a business bank account. This is because the company is legally distinct from its owners and therefore requires its own account. Even if you operate as a sole trader, you may choose to open a business bank account anyway to separate your personal and business finances. Business accounts typically make accounting and tax filing easier.
If you’re running a limited company in the UK, you’ll need to register for Corporation Tax with HMRC within three months of starting to trade. The same rule applies to unincorporated associations (like clubs and community groups) that turn profits and international companies with UK branches.
If your taxable turnover exceeds the Value Added Tax (VAT) threshold (£90,000 as of March 2026), you’ll need to register for VAT. This is a tax added to goods and services sold by VAT-registered businesses. Even if you’re below the threshold, you may want to voluntarily register for VAT. It can be beneficial if you make significant taxable purchases, as you can reclaim the VAT you’ve paid on them.
If you plan to have any employees or pay yourself a salary, you’ll also need to register as an employer with HMRC for PAYE before the first payday. This is how HMRC collects tax on wages. If you’re a sole trader, you’ll pay your taxes via Self Assessment instead.
While the various requirements can seem overwhelming for first-time founders, it becomes simpler over time. Once you’ve organised your finances and registered for taxes, you’ll be in a stronger position to operate compliantly and with a clearer understanding of your cash flow.
4. Know your legal and reporting responsibilities
Setting up your company is only the beginning. Meeting ongoing obligations is essential for keeping your business compliant.
When establishing your business, it’s important to understand how your chosen structure will affect regular responsibilities.
For example, if you’ve chosen to become a limited company, you’ll need to be prepared to file annual accounts with Companies House each year. This provides a snapshot of your company’s financial performance. You’ll also need to file your confirmation statement every year. In addition, you must submit a Company Tax Return to HMRC and pay Corporation Tax on profits.
Keeping accurate records as you go will make it easier to complete your tax returns, whether you’re doing so via Self Assessment or as part of a Company Tax Return.
If these responsibilities aren’t met, this may result in late filing penalties and, in some cases, company strike-off. Using an accountant and administrative services can help you understand your ongoing responsibilities and avoid missing important filing deadlines.
5. Put foundations in place to protect your business
It’s worth considering putting measures in place to protect your business from day one.
To start with, you should investigate the insurance policies you may need. If you’re employing staff, you’ll legally need employers’ liability insurance. You may also need other types of insurance, like public liability insurance (which protects against claims from customers or visitors relating to injury or property damage) and professional indemnity insurance (for cover against mistakes, advice errors, and any client losses caused by your services). Your needs will depend on your business activities. A legal advisor may be able to help you navigate which policies to take out.
It’s also important to protect your intellectual property (IP). You may want to register trademarks or apply for patents to stop competitors from copying you.
At the beginning of your journey, it’s also wise to draw up contracts that set clear terms with clients, employees, suppliers, and partners. You may want to seek legal advice here to ensure that you’re covering yourself against any risks while staying lawful.
Embracing risk-reduction measures like insurance, IP, and robust policies early on can help you protect your business from the beginning.
Setting your business up for long-term success
Building a strong business starts with choosing the right structure, registering properly, organising your finances, staying compliant, and putting protections in place.
As there is a lot to consider, many founders work with formation specialists like 1st Formations to simplify the process and reduce the admin burden. Formation specialists can guide founders through company registration and ongoing compliance requirements.
While setting up a business can be daunting, taking your obligations seriously from day one can help you build a strong foundation for a robust, sustainable business.
