Tax planning in Mayfair
Most tax is saved by decisions made before the year end, not by clever filing after it. People in Mayfair use our planning reviews to find out, in writing and with numbers, what their options are: how to pay themselves, when to take dividends, whether a pension contribution beats a salary rise, how to use both spouses' allowances. Fixed fee, no schemes.

Worth knowing
Rules that come up in this work
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition 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.
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.
Corporation Tax rates and marginal relief
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
Questions
Tax Planning questions from Mayfair
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.
Is tax planning advice regulated?
Tax advice is not a reserved activity in the UK, so no regulator licenses it, but we are bound by our terms of business and the advice disclaimer on this site, and we carry professional indemnity insurance. Advice is given in writing so that you can rely on it and we can be held to it.
What do I need to provide?
Your last tax return, the company's last accounts and current management figures if you have them, pension statements, details of other income and your spouse's position if relevant, and an idea of what you want from the business over the next few years. We send a short checklist when you book.
How much tax will a review save me?
It depends entirely on your position, and we would rather not promise a number. Common findings are a director salary set years ago at the wrong level, pension headroom unused, a spouse's allowances wasted, dividends bunched into one tax year and capital allowances missed. For most directors the saving exceeds the fee several times; where it would not, we say so before you pay.
Do you recommend tax avoidance schemes?
No. We use established reliefs and allowances that Parliament intended: pensions, ISAs, spousal transfers, capital allowances, dividend and salary structuring, timing. We do not sell arrangements that depend on HMRC not noticing. If someone offers you a scheme that sounds too good, the £249 review will tell you why it probably is.
How do I get started from Mayfair?
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 tax planning. Once you confirm, we tell you exactly which records to send and the work begins. Most Mayfair clients are set up within a day.
Which deadlines matter most for tax planning?
The next four dates that apply to tax planning are shown at the top of this page, calculated from today. For Mayfair 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.
