How to prepare for your financial year-end

Don’t be left floundering when your company hits the financial year-end. Let us help you through the process so you know exactly what you need to do, and how to best accomplish it.

With April just around the corner, you may well be about to hit your year-end. A bit like Christmas, you know it’s coming, but it never fails to sneak up year after year. Planning is paramount. Having a clearly defined  to-do list and timetable to carry out the necessary tasks will remove that last-minute panic and minimise your time on the process and the accompanying headaches. Ensure your records are up to date as you progress through the year and that each person involved knows what tasks they will need to  perform and has these built into their workload.

What is Financial Year-End?

It’s likely you are well aware of your financial year-end requirements but let’s clarify matters for those new to dealing with business paperwork. Your company’s financial year-end is the date your accounting period ends. Once hit, you have a limited window to submit mandatory paperwork. It’s also the best time to plan for growth and examine your current situation. Along with Companies House and HMRC, if you’re looking for a loan from lenders or acquiring an investment from potential investors, they will also be keen to see the reports.

The financial year-end is also commonly referred to as a fiscal year-end. The tax year for 2023 will close on April 5thso it is important that you submit your tax returns, statutory accounts, and VAT returns with plenty of time to spare to avoid late fines and penalties from HMRC.

What’s Due: Corporate Tax Returns

Maybe the most infamous of the financial year-end documents is the CT600, or Company Tax Return. This will contain the final figures for your company’s income and details of any tax allowances or expenses. Your remaining profit will be used to calculate your Corporation Tax liability for the period.

You will be required to file your tax return with HMRC online using your user ID and password. You will also need to send your company accounts to Companies House. Company tax returns must be submitted by everyone who runs a limited company.

What’s Due: Statutory Accounts

HMRC will also require your statutory accounts. These will need to include your Profit & Loss and Balance Sheet for the period, alongside any relevant footnotes and analysis.
If you are utilising FRS 105, the financial reporting standard for micro-entities, then you will only be required to submit your Statement of Financial Position and the accompanying footnotes.

Statutory accounts are your company’s annual accounts and are prepared from your financial records for that financial year.

What’s Due: VAT Return

If you’re VAT registered, it’s also likely you have a VAT return due at the same point in time. While it isn’t part of the financial year-end per se, it will be most easily dealt with while you are working through the figures.  Making tax digital was introduced in April 2022 and since it has never been more important to have your figures clearly organised in a digital format. You can submit your VAT Return through the Making Tax Digital system.

Preparation Work

To minimise disruption on an annual scale, ensure you have a clear plan and deadlines. Make sure your employees understand when the year-end takes place and know what will be expected of them around that time.

Make sure your accounts are up to date. Good accounting software can make or break you here. If you use software such as Xero, you should have all transactions uploaded alongside the paperwork to back them up. You will need to ensure everything is correctly recorded by reconciling your bank statements and outstanding debtors and liabilities.

You will also need to decide if you are issuing dividends to your shareholders. If you are, the correct paperwork will need to be created and the dividends included in your final accounts.

If HMRC query your accounts it will be a lot less stressful if you know you have everything to hand, be it digitally or in a traditional filing system. Check all documents have made it to their correct home. If they haven’t look at creating a document-handling process to give clear instructions to staff members.

It will also be beneficial to ensure you have your Government Gateway account details ready to hand to save stress on submission day. If you need to recover your Government Gateway ID, do so well before the deadline day. You do not want to receive a fine or late penalty from HMRC while you wait for new account information to be set up or because you couldn’t access your account.

 Additionally, ensuring that your company is VAT registered in advance will also help to reduce stress. If you are not sure when or how to register for VAT, click here.


This is also a good time to perform some housekeeping; if you have any bad debts that will not be paid, this is the time to tidy them up by writing them off.

If you use Xero or similar software, you will want to check the data and examine any issues flagged in reports. If everything looks as it should ensure you have a backup copy in the event of a system failure.

As part of the financial year-end scrutiny HMRC will examine your payroll and staffing expenses. Make sure your tax and National Insurance calculations are correct else you could end up footing an unexpected bill. If you need support or advice about how to calculate your National Insurance contributions, get in touch with an accountant today.

Your tax return deadline will be 12 months after the end of the year or the period that it covers. Your Corporation Tax will be due 9 months and 1 day after the end of your financial year. Your accounts will need to be with Companies House within 9 months of your year-end. These dates should be placed on your calendar but it’s worth remembering that getting them in early may save you deadline stress. It is also worth remembering that when you submit your tax return early any tax you overpaid from the previous year will also be refunded earlier helping to improve cash flow and planning.

Failure to file with HMRC will ensure late filing penalties. These begin at £100 for a day and double to £200 after 3 months. If you still haven’t filed, it is time to get an accountant involved and your penalty will now be a percentage of your tax bill. Failure to file with Companies House begins at £150 for a delay of up to a month. Failure to file in subsequent months can rack up quickly to £1,500 if you are more than 6 months late. And it’s worth noting that failure to meet the deadline in the subsequent year will double the penalties. Filing your tax return early also helps you avoid late penalties and ease the stress of submitting your tax return late.
