Worth knowing
Rules that come up in this work
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.
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.
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
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
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.
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.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Questions
Tax Planning questions from Isleworth
Will you implement the recommendations?
Where the actions fall within our services, such as setting the payroll salary, documenting dividends, adjusting the company's pension contributions or making an election, yes, as part of those services. Where they need a financial adviser, for example choosing pension investments, we tell you what to ask them.
How often should planning be reviewed?
Annually, ideally in the first quarter of the tax year so that decisions have the full year to work. Thresholds and rates change each April, your income changes, and the company's profit changes. Clients in our monthly packages get a planning conversation as part of the Complete and Premium tiers.
How does pension planning fit in?
Pension contributions get relief at your marginal rate, employer contributions are deductible for Corporation Tax and free of National Insurance, and unused annual allowance from the previous three years can be carried forward. For directors it is usually the most efficient extraction route after a basic salary. We calculate your headroom and the saving.
What about the personal allowance taper and the £100,000 trap?
Between £100,000 and £125,140 of adjusted income the personal allowance is withdrawn at £1 for every £2, producing an effective marginal rate of 60%. Pension contributions and gift aid reduce adjusted income and are often the best use of money in that band. The review quantifies this precisely for your figures.
What does the director remuneration review cover?
For £249 we model the coming year's salary, dividends, employer pension contributions and any benefits against the company's expected profit and your other income, showing the total tax and National Insurance under each option and recommending a structure. It includes the use of a spouse's shareholding and allowances where relevant.
What does the £249 personal tax review cover?
Your income from all sources, the allowances and reliefs you are and are not using, pension contribution headroom, the personal allowance taper and High Income Child Benefit charge if relevant, savings and dividend allowances, ISA use, marriage allowance, gift aid and the timing of any disposals. You receive a written report with quantified recommendations.
Is tax planning in Isleworth really the same price as elsewhere?
Yes. The fee published on this page is what a client in Isleworth 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 Isleworth?
No. IGI Accounting is an online-only firm. We serve Isleworth 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 tax planning is the same in Isleworth as anywhere else in the country, and why there is nothing to visit and nothing to print.
