Every self-employed sole trader must file a Self Assessment Tax Return (SA100) each year. We prepare and file this as a standalone service — though most of our clients find our all-inclusive MTD Sole Trader Packages better value, since ongoing bookkeeping and quarterly reporting are bundled in throughout the year rather than left to a single annual return.
For sole traders, annual accounts preparation is the key step before filing your Self Assessment Tax Return (SA100). We ensure your income, expenses, and capital allowances are calculated correctly to minimise your tax liability and keep you compliant with HMRC.
If your income is over £50,000, Making Tax Digital for Income Tax (MTD ITSA) compliance starts in April 2026. This means mandatory quarterly reporting.
Avoid complexity and fines by choosing our all-inclusive MTD Sole Trader Accountancy Package which handles all bookkeeping, quarterly updates, and your final tax return for a fixed monthly fee.
Self Assessment runs to a strict annual calendar, and HMRC's penalties apply automatically — even if you don't owe any tax:
To prepare your return, we'll typically ask for your income and expense records, bank statements, and details of any other income you receive — such as employment, property, or dividend income. If you already keep your own records in software such as Xero, we can work directly from your existing figures.
We offer standalone Annual Accounts and Tax Return filing for clients who manage their own comprehensive bookkeeping.
Prices start from £150 (Self Assessment) plus £50 per Self Employment business.
Additional sections (Employment Income, Property Income etc) are £20 per section , or are determined by complexity, as outlined in your initial proposal.
Whether you need a full package or a one-off filing, contact us for a clear, fixed quote.
While sole traders aren't required to submit accounts to Companies House, maintaining clear annual accounts helps with accurate Self Assessment tax returns and financial planning.
Standalone Self Assessment Tax Returns start from £150, plus £50 per self-employment business, and £20 per additional section such as Employment or Property Income — or as set out in your fixed-fee proposal. If you're on our MTD Sole Trader Package, this is already included.
Yes, we provide MTD ITSA support for self-employed individuals, ensuring full digital record keeping and quarterly submissions from 2026 onwards.
If you're newly self-employed, you must register with HMRC by 5 October following the end of the tax year. Paper returns are due by 31 October, online returns by 31 January, and any tax owed is also due by 31 January.
HMRC charges an automatic £100 penalty for a late return, even if you owe no tax, rising to £10 a day after three months (up to £900), with further penalties at 6 and 12 months. Interest is also charged on any tax paid late.
