Worth knowing
Rules that come up in this work
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Corporation Tax rates and marginal relief
Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.
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.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
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.
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.
Questions
Contractor Accountants questions from Blackfen
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.
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.
How should I pay myself from the company?
The usual approach is a salary around the National Insurance thresholds, which keeps your State Pension record intact and is deductible for Corporation Tax, with the rest as dividends taxed at the dividend rates after the £500 allowance. The exact split depends on your other income and the company's profit, and we set it at the start of each tax year.
What is IR35 and does it affect me?
IR35 asks whether, but for the company, you would be an employee of your client. If a contract is inside IR35 the income is taxed like employment. Since 2021 medium and large private-sector clients make the determination and deduct tax at source; for small clients the contractor decides. We review contracts and working practices and give a written opinion for £99.
What is in the £75 Essential package?
Annual statutory accounts and CT600 filed with Companies House and HMRC, monthly director payroll with RTI submissions, dividend vouchers and minutes, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. It suits contractors outside VAT or who prefer to do their own VAT and bookkeeping.
I am about to leave permanent employment to contract. Where do I start?
With the company formation and the first contract review. Our £99 formation-plus-registrations package sets up the company with Corporation Tax and PAYE registered; the IR35 review of your first engagement decides how the income will be taxed. Join the Essential package from the month you start invoicing.
Do you have an office in Blackfen?
No. IGI Accounting is an online-only firm. We serve Blackfen 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 contractor accountants is the same in Blackfen as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is contractor accountants in Blackfen really the same price as elsewhere?
Yes. The fee published on this page is what a client in Blackfen 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.
