Worth knowing
Rules that affect most businesses here
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Corporation Tax rates and marginal relief
Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.
Questions
Questions from Milton
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 Milton, Portsmouth 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 Milton 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 East that are not in Milton itself?
Yes. Every place in South East 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 Milton 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 Milton, Portsmouth: records in, draft out, approve, filed.
How do I get started from Milton, Portsmouth?
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 Milton 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 Milton 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.
