Worth knowing

Rules that come up in this work

The VAT registration threshold

VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.

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.

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.

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.

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.

Payments on account

If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.

Late filing penalties

Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.

Questions

Limited Company Accounts questions from Mansion House

Does the fee include Corporation Tax?

Yes. Both the £299 micro-entity and £449 small company packages include the Corporation Tax computation, the CT600 and electronic filing with HMRC. The standalone CT600 at £199 is for companies whose accounts are prepared elsewhere.

Can you include my personal tax return?

The £389 bundle covers micro-entity accounts, the CT600 and the director's Self Assessment return together. It is cheaper than buying them separately and ensures the dividends and salary on the personal return match the company's records exactly.

How do dividends work and how much can I take?

Dividends can only be paid from accumulated profits after Corporation Tax. We calculate the distributable reserves in your accounts and tell you the figure. Dividends need a board minute and a voucher each time; we provide templates. The personal tax on dividends depends on your other income, and the planning review covers that.

What is a director's loan account and why does it matter?

It records money moving between you and the company that is not salary or dividend. If you owe the company money at the year end and have not repaid it within nine months, the company pays 35.75% section 455 tax on the balance, refundable later. We review the account before finalising and tell you the options.

What is the difference between micro-entity and small company accounts?

A micro-entity has turnover under £1 million, a balance sheet under £500,000 and up to 10 employees (thresholds from April 2025) and may file abbreviated accounts with very few notes, at our £299 fee. Companies above those limits but still "small" file fuller accounts with more disclosures, at £449. We confirm which you are from your figures.

What do you need from me to prepare the accounts?

Bank statements for the full year, sales and purchase records or your bookkeeping software login, details of any assets bought or sold, loans, and the previous year's accounts and CT600 if we did not prepare them. If your books are not kept, the "from bank statements" approach works but may move you to the small company fee.

Which deadlines matter most for limited company accounts?

The next four dates that apply to limited company accounts are shown at the top of this page, calculated from today. For Mansion House 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.

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 limited company accounts. Once you confirm, we tell you exactly which records to send and the work begins. Most Mansion House clients are set up within a day.
