What should limited company directors know about bookkeeping?

If you are a new limited company director, ‘bookkeeping’ in some form is essential to organising your company finances.

It allows you to keep up-to-date records of both your income (often from contracts) and your outgoings (including allowable director expenses).

In this article, we look at everything to do with bookkeeping for limited companies: from the basics to the regular tasks which you, as a director, are likely to become familiar with.

What is bookkeeping?

Starting with the basics, bookkeeping is the record-keeping of your limited company’s financial transactions.

This can involve records of sales (for example, contract invoices), payments received, purchases, expenses, and receipts by your company or yourself as a director.

Bookkeeping is typically overseen by a bookkeeper (or by you initially), who ensures that all transactions are collated and recorded.

Your accountant can then use these records to prepare statutory accounts, your Corporation Tax Return, and other reports.

Bookkeeping: The essential details

One of the most important uses of bookkeeping records is the preparation of the statutory financial statements needed to submit your company accounts to Companies House (normally due 9 months after your year-end) and to support your Company Tax Return to HMRC (due 12 months after the end of the relevant Corporation Tax accounting period).

Remember that for a normal small company, Corporation Tax itself is generally due 9 months and 1 day after the end of the accounting period, before the deadline for filing the Company Tax Return.

Your bookkeeping process will need to include information on your contract income or sales, expenses (including director-allowable expenses such as mileage, home office, and training), any employees’ salaries (if applicable), and payments to yourself as a director (salary and dividends).

Many directors use an accountant to deal with their accounts and tax filings, especially contractors who prefer to outsource the work and avoid the time drain.

Bookkeeping for limited company directors

Not all limited company directors choose to do their own bookkeeping.

It often depends on your resources, whether you have employees, and the volume of transactions.

It is worth bearing in mind that outsourced bookkeepers or specialist contractor accountants can often save you a lot of time, thanks to their experience with limited company tasks such as expense claims and dividend planning.

Should you choose to do your bookkeeping in-house (common for new contractors), review the lists below for some tasks you can expect.

However, in most cases, you will use cloud-based accounting software (and/or an accountant) to minimise the amount of time you, as a director, have to spend keeping your records up-to-date.

Tools like Xero (80% off for 6 months) and FreeAgent (30-day free trial, 10% off for life) with bank feeds are particularly popular among contractors for auto-reconciliation.

Regular Tasks

Among those tasks which you can expect to undertake daily or weekly are:

• Creating and sending invoices is key to tracking contract payments coming into your company and ensuring steady cash flow.
• Filing invoices and receipts: You should keep copies (digital or physical) of documents such as supplier invoices, expense receipts, and proof of payments you make. Company accounting records generally need to be kept for 6 years from the end of the financial year they relate to, and sometimes longer in certain circumstances.
• Cash monitoring: Your bank balance and cash position should be monitored on an ongoing basis to ensure you have sufficient funds to cover payments, such as VAT or Corporation Tax.
• Outgoing payment strategy: You can often gain discounts by making early payments to suppliers, and you must track what your company owes so that you do not miss deadlines.

Periodical Tasks

Other bookkeeping tasks are done monthly or quarterly, but are no less important. These include:

• Review incoming payments: Track what clients owe your company and promptly chase up any late contract payments.
• Payroll: if you pay yourself a salary (or have employees), handle PAYE deductions and report payroll information to HMRC on or before payday under RTI.
• VAT: if registered, use MTD-compatible software to keep the required digital records, submit VAT Returns and pay any VAT due according to your VAT accounting period.
• Monthly turnover and profit review: calculating this is an essential barometer for seeing whether your contracting business is growing; monitor trends in contract income vs. expenses.

Year-end and annual obligations

Your bookkeeping records are also needed for a number of important year-end and annual obligations.

• Annual accounts: Limited companies are required to file company accounts every year with Companies House. For most private companies, the deadline is 9 months after the year-end, although different rules apply to first accounts. Small and micro companies can currently omit certain information from the accounts placed on the public register. From 1 April 2028, small and micro companies will have to file a profit and loss account with Companies House, although qualifying companies will be able to opt out of having it displayed publicly.
• Corporation Tax: Your bookkeeping records are used to calculate the company’s Corporation Tax liability and support the accounts submitted to HMRC as part of the Company Tax Return.
• Confirmation Statement: Your company must also file a Confirmation Statement with Companies House at least once every 12 months. This is a separate company filing rather than part of your annual accounts.

Quick tips for limited company directors

If you are a limited company director (especially a contractor) committed to conducting your own bookkeeping, we have put together this list of quick tips to help you on your way:

• Accept a helping hand; there is plenty of sound advice available, including HMRC’s videos and webinars, as well as contractor-specific forums and guides.
• As a limited company, you can claim your expenses where they meet the relevant tax rules, generally including costs incurred wholly and exclusively for the purposes of the trade. Common examples for contractors can include mileage to qualifying business destinations, home office costs, professional subscriptions, and qualifying training costs. If VAT registered, you may also be able to reclaim input VAT on qualifying business purchases. For this reason, it is essential that you keep accurate records and receipts for everything.
• Work smarter, not harder. There is a plethora of accounting software packages on the market that can make bookkeeping more efficient and accurate (many of which offer bank auto-feeds and MTD VAT compliance). Choose a package that suits your budget and requirements to save yourself precious time.
• Don’t forget to budget for taxes. Set aside funds monthly for Corporation Tax, VAT (if applicable), and any personal tax. You should only ever draw down dividends where the company has sufficient profits available for distribution.
