Year-end accounts
and tax

Your year-end should be just another month-end

Your year-end accounts should fall out of your bookkeeping software – with no surprises.

Dates and deadlines:

  • Accounts need to be filed at Companies House within nine months of your year-end
  • An estimate of corporation tax needs to be paid within nine months and one day of your year-end
  • Your corporation tax return needs to be filed with HMRC within twelve months of your year-end

It’s useful to wait two or three months just to make sure everything has been accounted for properly.

There may be events and information arising in the new financial year that need to be reflected in last year’s accounts.

And often there are items of information that need to be disclosed and explained in your accounts that need to be collated. The common ones are:

  • Overdrawn directors’ accounts
  • Future lease obligations
  • Transactions with related parties
  • Number of employees during the year

Your company accounts flow into your corporation tax return and both are prepared at the same time.

The winds of change are blowing

For years, nothing much has changed in the world of year-end accounts but all of a sudden a great deal is changing.

Companies House are mandating that:

  • All directors and People with Significant Control must verify their identity
  • All accounts must be submitted using commercial accounting software – no more paper accounts and the Companies House web filing service will be withdrawn
  • All companies will have to file their P&L as part of their accounts (this change is currently under review)

At the same time, there are wide-ranging changes to the accounts that need to be produced by a company.

Firstly, the size thresholds defining small, medium and large companies are increasing so there will be more small and medium companies.

Secondly, there are changes to accounting rules which will change how some transactions are accounted for and increase the information to be disclosed in published accounts.

We’re all going to have to plan and think carefully about year-end accounts for a while.

Making Tax Digital for Income Tax (MTD)

If you’re self-employed or a landlord then you need to pay attention to MTD.

The basic rules are that from April 2026 the self-employed and landlords must keep digital financial records and they will need to make quarterly filings of income and expenditure to HMRC.

The rules apply first of all to self-employed people and landlords whose sales and rents exceed £50,000 and this threshold will fall in future years.

Our message to all self-employed people and landlords is two-fold:

  1. Make sure you have separate bank accounts that are ONLY used for your self-employed business or your property transactions
  2. Get going with your bookkeeping

This is sensible whether you’re caught by the £50,000 threshold or not.

Concentrate on the Digital and the Tax will not be a headache.

FAQs

Limited companies must file:

  • Accounts at Companies House within 9 months of year-end
  • Corporation Tax returns within 12 months. But an estimate of corporation tax is payable nine months and one day after your year-end

We’ll handle both and keep you ahead of deadlines.

Your accounts include:

  • Profit & Loss – performance over the year
  • Balance Sheet – what the company owns and owes
  • Notes – explaining key figures

Over the next couple of years more information will be required in the notes as the rules governing accounts disclosure are changing.

It’s the tax on company profits. The rate of tax starts at 19% for profits below £50,000 and rises to 25% as profits rise towards £250,000.

If you control more than one company these thresholds reduce and each company reaches the 25% rate sooner.

We calculate it accurately and help you plan for it throughout the year.

Only a summary version is publicly available. Just your balance sheet and related notes. Your P&L stays private – for now!

If your turnover exceeds £90,000, VAT registration is required. Below that, voluntary registration may still make sense — we can help you decide.

Yes — up-to-date books mean smoother, faster year-end work and fewer surprises.
