A simple guide to accounting for a new UK company, covering bookkeeping, Corporation Tax, VAT, annual accounts and key filing requirements for non-UK residents.
Setting up a UK limited company as a non-UK resident can provide access to one of the world's most established business environments. However, registering the company is only the beginning. Once your company is incorporated, you also need to understand your UK accounting, tax and reporting responsibilities.
Even if you live and operate your business outside the United Kingdom, a UK-registered company will normally have ongoing obligations with Companies House and HM Revenue & Customs (HMRC).
This guide explains the key accounting requirements for a new UK company, including bookkeeping, annual accounts, Corporation Tax, VAT, payroll and important filing deadlines.
Yes. Every UK limited company must maintain appropriate accounting records.
Your records should provide enough information to show the company's financial position and explain its transactions. This applies whether the company is actively trading or currently dormant.
For non-UK residents, it is particularly important not to assume that living outside the UK removes the company's UK reporting responsibilities. The company remains a UK-registered legal entity and must comply with the applicable filing and accounting rules.
Good bookkeeping is one of the most important steps after forming your UK company.
You should keep accurate records of money entering and leaving the business, including:
Keeping your records organised from the beginning can make preparing annual accounts and tax returns significantly easier.
It can also help you understand whether the company is profitable and how much money may need to be reserved for tax.
A UK limited company is legally separate from its owners.
For that reason, it is generally good practice to keep company transactions separate from your personal finances.
A dedicated business account or suitable business payment account can make it much easier to track income and expenses and provide accurate records to your accountant.
This can be especially useful for international founders receiving payments in currencies such as GBP, EUR and USD.
When transferring money between yourself and the company, make sure the transaction is recorded correctly. Depending on the circumstances, money moving between a director and the company may need to be treated as salary, dividends, expenses, capital introduced or a director's loan.
Your company's financial year determines the period covered by its annual accounts.
For a newly incorporated UK company, the first accounting period can be slightly different from later accounting periods, so new company owners should check the specific dates assigned to their company rather than assuming the period is exactly 12 months.
You can check your company's filing dates and accounting reference date through Companies House.
Missing an accounts filing deadline can result in penalties, so it is worth recording the deadline as soon as your company is incorporated.
UK limited companies generally need to prepare annual accounts.
Depending on the company's circumstances and size, these may include information such as:
Balance Sheet
Shows what the company owns, what it owes and its financial position at the end of the accounting period.
Profit and Loss Account
Shows the company's income, expenses and profit or loss during the accounting period.
Notes to the Accounts
Provides additional information explaining figures contained within the financial statements.
The exact accounts that must be prepared and filed can vary depending on the company's size and circumstances.
Small companies and micro-entities may qualify for simplified reporting requirements if they meet the relevant criteria.
Corporation Tax is a major consideration for anyone operating a UK limited company.
When your company starts carrying on business activity, you need to ensure HMRC is informed as required and that the company's Corporation Tax responsibilities are properly managed.
Corporation Tax is generally calculated based on the company's taxable profits rather than its total revenue.
For example, if a company generates £100,000 in revenue, this does not necessarily mean Corporation Tax is calculated on the entire £100,000.
Allowable business expenses and other relevant tax adjustments can affect the company's taxable profit.
This is one reason accurate bookkeeping is so important.
A common mistake made by new business owners is treating all the money in the company's bank account as available to spend.
Part of that money may ultimately be required to pay tax.
Consider estimating your company's tax liability throughout the year and keeping sufficient funds available for upcoming payments.
Accounting software or an accountant can help you monitor your expected profit and potential tax position.
Companies within the Corporation Tax regime generally need to submit a Company Tax Return to HMRC for the relevant accounting period.
The Corporation Tax Return is separate from the annual accounts filed with Companies House, although information from the company's accounts is used when preparing the tax return.
It is important to understand that there can be different deadlines for:
Do not assume that all three happen on the same date.
Owning a UK company while living abroad can create more complex tax questions.
The company may have UK Corporation Tax obligations, while you personally may also have tax obligations in the country where you live.
Issues can arise around:
Simply registering a company in the UK does not automatically determine every aspect of its international tax position.
If you manage your UK company from another country, obtaining professional cross-border tax advice can be particularly important.
Not every new UK company needs to register for VAT immediately.
Whether VAT registration is required can depend on factors including the company's taxable turnover and the nature and location of its activities.
Some companies may also choose to register voluntarily where permitted.
VAT can become more complicated for businesses selling internationally, particularly companies involved in:
Do not assume that having a UK company automatically means every invoice should include UK VAT.
The correct VAT treatment depends on the transaction.
Non-UK residents frequently establish UK companies to operate online businesses.
If you run an e-commerce business, your accounting records may need to reconcile transactions from multiple platforms and payment providers.
For example:
Customer Payment → Payment Processor → Fees Deducted → Business Account
The amount deposited into your account may therefore be lower than the actual sale value.
Your bookkeeping should distinguish between the original sale and the processing fees rather than simply recording the net bank deposit as revenue.
You may also need to account for refunds, chargebacks, marketplace fees, advertising expenses, shipping costs and currency conversion charges.
International UK companies often receive and make payments in multiple currencies.
For example, your company may:
However, UK statutory accounts are generally prepared in an appropriate presentation currency, so foreign-currency transactions may need to be converted and accounted for correctly.
Exchange-rate movements can also create foreign-exchange gains or losses.
Using accounting software that supports multiple currencies can make this considerably easier.
Company money and personal money should not be treated as the same thing.
If you are a director or shareholder, money taken from the company should be properly classified.
Depending on the circumstances, payments might be treated as:
Each can have different accounting and tax consequences.
For non-UK residents, the situation can be more complicated because the tax rules of your country of residence may also apply.
Before regularly withdrawing company funds, consider getting advice from an accountant familiar with international company owners.
If your UK company employs staff or pays directors through payroll, it may need to register as an employer and operate PAYE.
Payroll responsibilities can include calculating and reporting:
Paying an overseas director can require additional consideration because their residence and working arrangements may affect the appropriate treatment.
Accounting is not the only annual responsibility of a UK company.
Companies generally need to file a confirmation statement with Companies House.
The confirmation statement is used to confirm that important information Companies House holds about the company is accurate and up to date.
This can include information relating to the company's:
The confirmation statement is separate from the company's annual accounts.
If important company details change, you may need to notify Companies House rather than simply waiting for the next annual filing.
This may include changes involving directors, the registered office or other company information.
Keeping your company records current can help avoid compliance problems later.
UK companies are generally required to retain accounting records for a specified period.
These records can include:
Electronic record keeping is widely used and can make it easier for international directors to manage a UK company remotely.
For most active companies, accounting software can make financial management much easier.
Modern accounting platforms can help with:
Popular accounting platforms used by UK businesses include Xero, QuickBooks and FreeAgent.
The best choice will depend on your company's transaction volume, currencies, VAT position and business model.
It is possible for company owners to handle some accounting responsibilities themselves, particularly for straightforward businesses.
However, using a qualified accountant can be valuable when you are a non-UK resident.
An accountant may help with:
For an overseas owner, it can be particularly useful to choose an accountant experienced with UK companies owned by non-UK residents.
Many accounting problems can be prevented by establishing good processes immediately after incorporation.
Common mistakes include mixing personal and company transactions, failing to keep invoices and receipts, missing filing deadlines, incorrectly recording director withdrawals, forgetting Corporation Tax obligations and misunderstanding VAT.
International founders should also avoid assuming that UK incorporation means they have no tax obligations in their country of residence.
Cross-border taxation depends heavily on the individual circumstances of the company and its owners.
After registering your UK company:
Accounting for a new UK company does not need to be complicated, but it should be organised from the beginning.
For non-UK residents, the most important point is that forming a UK company creates ongoing responsibilities. Registering the company is only the first step.
Good bookkeeping, understanding Corporation Tax, monitoring VAT requirements and keeping track of Companies House and HMRC deadlines can help keep your company compliant and avoid unnecessary penalties.
International founders should also consider how operating a UK company affects their tax position in their country of residence.
When cross-border tax issues are involved, professional advice from an accountant or tax adviser familiar with both UK companies and international business owners can be particularly valuable.
