Worth knowing
Rules that affect most businesses here
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
Questions
Questions from Borough Market
Are your fees inclusive of everything?
Our fee covers the work described for the package. Companies House fees, such as £100 to incorporate or £50 for a confirmation statement, are charged separately and passed on at cost. Software subscriptions are in your own name. There is nothing else: no hourly extras, no charge for questions, and no additional year-end invoice for Borough Market clients on monthly packages.
How quickly do you respond?
In UK working hours, usually within a few hours and always the same working day. Each Borough Market client has a named contact who knows the file. Outside working hours, WhatsApp and email messages are picked up first thing the next morning. In January and at other peak times we tell you your turnaround when you book rather than leaving you guessing.
Do you work with businesses in South London that are not in Borough Market itself?
Yes. Every place in South London has its own page on this site and the same fees apply throughout. The nearest-places list on this page links to them. Wherever in England your business is based, the service is identical because none of it depends on where you are.
What if my Borough Market business is a partnership or an LLP?
Both are covered. Partnerships need a partnership return and a Self Assessment for each partner; LLPs file accounts with Companies House under company-style rules as well. We quote a fixed fee for the set based on the number of partners or members, and the process is the same as for any other client in Borough Market: records in, draft out, approve, filed.
How do I get started from Borough Market?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for self assessment tax returns. Once you confirm, we tell you exactly which records to send and the work begins. Most Borough Market clients are set up within a day.
Which deadlines matter most for self assessment tax returns?
The next four dates that apply to self assessment tax returns are shown at the top of this page, calculated from today. For Borough Market clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
