Worth knowing

Rules that come up in this work

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.

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.

Director's loan accounts

Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.

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

Contractor Accountants questions from South Twickenham

What happens between contracts?

The company continues and so do the filings, but we can reduce the salary and pause dividends. If you expect a long gap we discuss whether to keep the company trading, make it dormant or close it. The monthly fee continues while the company is active because the compliance does, but we review it with you if circumstances change.

Can the company pay into my pension?

Yes, and it is one of the most efficient ways to extract value. Employer pension contributions are deductible for Corporation Tax, free of National Insurance and not taxed on you, up to the £60,000 annual allowance (tapered for very high earners). We include pension planning in the Complete package's annual call.

Can I claim travel and subsistence?

For engagements outside IR35, travel to a client site that is a temporary workplace is claimable, subject to the 24-month rule: once you know an engagement will exceed 24 months at the same site, it stops being temporary. Subsistence follows the travel. Inside-IR35 engagements lose these claims. We check each engagement.

My client has put me inside IR35. Should I still use my company?

It can still be worth it if you have other outside-IR35 work, but for a single inside-IR35 engagement an umbrella company or direct PAYE is often simpler and cheaper. We run the comparison for your specific numbers and tell you honestly, even if the answer is that you do not need us for that contract.

What is the flat rate VAT scheme and should I use it?

For most contractors with low costs the limited-cost-trader rate of 16.5% removes any advantage of the flat rate scheme, and the standard scheme reclaiming input VAT on equipment and software is better. Contractors with significant qualifying costs may differ. We calculate both at registration and review annually.

How are dividends documented?

Each dividend needs a board minute approving it and a dividend voucher recording the date, amount and shareholder. The company must have sufficient distributable profits after tax at the time. We check the reserves before each dividend, produce the paperwork and keep it on file, because undocumented dividends are reclassified by HMRC as salary or loans.

Is contractor accountants in South Twickenham really the same price as elsewhere?

Yes. The fee published on this page is what a client in South Twickenham 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.

No. IGI Accounting is an online-only firm. We serve South Twickenham and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.
