Why IGI
What you get in Wimbledon
No hourly rate and no surprise invoice. Wimbledon clients know the fee for cash-flow forecasting before they send a single document, and it stays fixed.
We work to the HMRC and Companies House calendar, not an appointment diary. Clients in Wimbledon get reminders at 60, 30 and 7 days before each date that applies to cash-flow forecasting.
Online only, UK based. There is no office in Wimbledon to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.
Continuity matters in cash-flow forecasting: the person who prepared last year's work for your Wimbledon business prepares this year's, and remembers what was agreed.
We explain cash-flow forecasting in the words Wimbledon business owners use, not in accountant's shorthand, and we show our working so you can check it.
Nothing is filed for Wimbledon until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.

Worth knowing
Rules that come up in this work
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
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
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
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.
The VAT registration threshold
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
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
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Questions
Cash-Flow Forecasting questions from Wimbledon
What happens after the forecast is delivered?
You receive the model, a briefing call to walk through it, and a written note of the assumptions and the pinch points we see. You can run it yourself from there, or take the £99 monthly refresh so we keep it live. Many clients start with a one-off forecast and move to the retainer once they see its value.
How quickly can you produce a forecast?
A 13-week forecast within five working days of receiving your data; a 12-month forecast with scenarios within ten. Funding packs depend on the lender's format but typically two weeks. If you have a deadline for an application, tell us when you book and we plan backwards from it.
Can a forecast show me whether I can afford a hire or a purchase?
Yes, that is one of its main uses. We add the hire or purchase as a scenario and show the cash effect month by month, including the point at which it pays for itself if it does. Decisions that look fine on a profit basis often fail on cash timing, and the forecast shows where.
How do seasonal businesses use forecasting?
To see the trough. Seasonal businesses typically make their profit in a few months and spend the rest of the year surviving on it, with VAT and tax payments falling in the quiet period. The 12-month forecast shows how deep the trough goes and whether a facility is needed to bridge it, well before the bank does.
What is a 13-week rolling forecast?
A week-by-week projection of cash in and cash out for the next quarter, built from your debtor book and payment patterns, your creditors and their terms, payroll, rent, loan repayments and every tax date, giving the forecast bank balance at the end of each week. It is the standard tool for managing short-term cash and is refreshed as actuals arrive.
How is the £199 forecast built?
From your bookkeeping and bank data, your aged debtors and creditors, your payroll, your known commitments and the tax calendar. We analyse how quickly your customers actually pay rather than when they are due, which is where most forecasts go wrong, and we document every assumption so you can change it. You receive the model and a short briefing.
Which deadlines matter most for cash-flow forecasting?
The next four dates that apply to cash-flow forecasting are shown at the top of this page, calculated from today. For Wimbledon 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.
How do I get started from Wimbledon?
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 cash-flow forecasting. Once you confirm, we tell you exactly which records to send and the work begins. Most Wimbledon clients are set up within a day.
