Staying on top of your reporting obligations isn’t just about ticking boxes for HMRC and Companies House; it’s about maintaining transparency, staying compliant and making informed decisions to drive your business forward.
In this article, we’ll break down the key financial reporting obligations that every UK small business owner should know, so you can stay organised and stress-free.
1. Annual Accounts
If you operate as a limited company, you’re required to prepare and file annual accounts. We offer can this accountancy service for your limited company, filing your accounts with Companies House. These accounts provide a snapshot of your business’s financial performance and include:
- Profit and Loss Statement: Summarises your income and expenses over the financial year.
- Balance Sheet: Shows your business’s assets, liabilities and equity at the year-end.
- Notes to the Accounts: Explains specific figures or policies in more detail.
Deadlines:
- You must file your accounts within 9 months of the end of your company’s financial year.
Top Tip: Small businesses can file simpler “micro-entity accounts” if they meet certain criteria, reducing the administrative burden.
2. Corporation Tax Returns (CT600)
If your business is a limited company, you’re also required to submit a corporation tax return to HMRC. This involves:
- Reporting your taxable profits.
- Calculating how much corporation tax you owe.
Deadlines:
- Your tax return is due 12 months after the end of your accounting period.
- Payment of corporation tax is due 9 months and 1 day after your accounting period ends.
Make sure to keep accurate records of income and expenses throughout the year to make tax filing smoother.
3. Self-Assessment Tax Returns
Sole traders, partnerships, and some company directors must file a self-assessment tax return each year. This involves:
- Declaring your income from all sources, including your business profits.
- Claiming allowable expenses and tax reliefs.
Deadlines:
- Online tax returns are due by 31st January following the end of the tax year.
- Any tax owed must also be paid by this date, along with the first payment on account for the next tax year.
Top Tip: Register for self-assessment as soon as you start trading to avoid late penalties.
4. VAT Returns
If your business turnover exceeds the VAT threshold (£90,000 as of 2025), you must register for VAT and submit VAT returns. These returns:
- Report the VAT you’ve charged on sales.
- Deduct the VAT you’ve paid on business expenses.
Deadlines:
- VAT returns are typically due quarterly, and payments must be made at the same time.
Tip: Even if you’re below the threshold, voluntary registration could be beneficial if you deal with VAT-registered suppliers.
5. Payroll and PAYE Reporting
If you employ staff, you’ll need to handle payroll and report to HMRC under the Pay-As-You-Earn (PAYE) system. This involves:
- Calculating and deducting Income Tax and National Insurance contributions.
- Providing employees with payslips and P60s.
- Submitting Real-Time Information (RTI) to HMRC every time you run payroll.
Deadlines:
- RTI submissions must be made on or before each payday.
- PAYE payments are due by the 22nd of the following month (19th if paying by cheque).
6. Confirmation Statement
Every limited company must file a confirmation statement with Companies House once a year. This updates your company’s registered details, including:
- Directors and shareholders.
- Registered office address.
- Share capital structure.
Deadlines:
- You must file the confirmation statement within 14 days of the due date, which is the anniversary of your company’s incorporation or the date of your last statement.
Tip: Even if no details have changed, you still need to submit the statement.
7. Record-Keeping Requirements
Accurate and organised record-keeping is essential for all businesses. HMRC requires you to keep records for:
- 5 years after the submission deadline for self-assessment tax returns.
- 6 years for VAT and PAYE records.
Ensure you keep digital copies of invoices, receipts and other financial documents, as they may be requested during an audit.
How to Stay on Top of Your Obligations
Managing these financial reporting tasks can feel overwhelming, but a few simple steps can make life easier:
- Use Accounting Software: Tools like Xero, QuickBooks, or FreeAgent can automate much of the process and keep you organised.
- Hire an Accountant: An experienced accountant can handle reporting tasks, ensure compliance, and provide strategic advice.
- Set Reminders: Mark key deadlines on your calendar to avoid penalties.
- Stay Informed: Tax rules and thresholds change, so keep up-to-date with the latest guidance from HMRC and Companies House.
