Worth knowing
Rules that come up in this work
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.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
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
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.
Director's loan accounts
The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.
Salary versus dividends
The salary-and-dividend split is the central planning decision for an owner-managed company. Salary costs employer National Insurance above £5,000 but is deductible; dividends are not deductible but attract lower personal rates and no National Insurance. The optimum changes each April with the thresholds and depends on the director's other income, so it should be set deliberately every 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
Small Business Accountants questions from Longthornton
Do you charge for phone calls and questions?
No. The monthly fee covers questions during the year. We would rather you ask before making a decision than pay us to unpick it afterwards. Formal advisory work, such as a tax planning review or a cash-flow forecast, is a separate fixed-fee product and we tell you when something falls into that category.
How does switching from my current accountant work?
You authorise us, we write to your current accountant for professional clearance and your records, and they are obliged to hand over your own documents. Most do within two weeks. We pick up the bookkeeping where they left off and take over the next filing. There is no charge for the switch.
What if my transaction volume is higher than the package covers?
We check the volume from your bank statements before quoting and tell you the right band. If the business grows and the volume increases, we review quarterly and adjust from the next month with notice. There is no back-charging for a busy period.
Can you handle a partnership?
Yes. Partnerships need a partnership tax return showing the profit split and each partner's own Self Assessment. The Core package covers the partnership return and bookkeeping; each partner's personal return is added at the published £129. LLPs follow company-style accounts rules and we handle those too.
When do I need Complete?
When you are VAT registered or employ staff. Complete at £125 adds quarterly VAT returns and payroll for up to five employees including auto-enrolment, so the quarterly and monthly cycles are handled alongside the annual ones. Businesses with more staff or higher transaction volumes are quoted a fixed fee before joining.
What is in the £65 Core package?
Monthly bookkeeping from your bank feeds with receipts captured by phone, a monthly summary, your annual accounts and tax return (Corporation Tax and CT600 for a company, Self Assessment for a sole trader), the confirmation statement for a company (Companies House £50 fee separate), and deadline tracking with reminders. Transaction volume up to around 150 a month.
Is small business accountants in Longthornton really the same price as elsewhere?
Yes. The fee published on this page is what a client in Longthornton pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
Do you have an office in Longthornton?
No. IGI Accounting is an online-only firm. We serve Longthornton and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for small business accountants is the same in Longthornton as anywhere else in the country, and why there is nothing to visit and nothing to print.
