Worth knowing
Rules that affect most businesses here
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
Confirmation statements and identity verification
The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.
Payments on account
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
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 Dartmouth Park
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 Dartmouth Park 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 Dartmouth Park 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 North London that are not in Dartmouth Park itself?
Yes. Every place in North 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 Dartmouth Park 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 Dartmouth Park: records in, draft out, approve, filed.
How do I get started from Dartmouth Park?
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 Dartmouth Park 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 Dartmouth Park 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.
