Why IGI
The IGI way of working, in Westminster
No hourly rate and no surprise invoice. Westminster 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 Westminster 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 Westminster 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 Westminster business prepares this year's, and remembers what was agreed.
Plain English, with the numbers. Every draft for Westminster comes with a short explanation of what the figures mean and what, if anything, you should do about them.
You stay in control of cash-flow forecasting: drafts go to Westminster clients first, with the figures explained, and nothing leaves us until you say so.

Worth knowing
Rules that come up in this work
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
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.
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
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end 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.
Questions
Cash-Flow Forecasting questions from Westminster
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 in the funding-application pack?
For £299: a 12-month forecast with monthly cash flow, profit and loss and balance sheet, an assumptions schedule, sensitivity analysis showing what happens if sales fall or costs rise by set percentages, and a narrative explaining the business and the use of funds in the terms lenders and grant bodies use. We brief you on the questions they will ask.
Will banks accept your forecasts?
Yes. Lenders see forecasts constantly and recognise one built from real data with documented assumptions. Grant bodies and investors likewise. We produce covenant calculations and any specific format a lender requires, and we are happy to speak to the lender with you about the assumptions.
Why do forecasts usually go wrong?
Three reasons: they assume customers pay on the due date, they forget tax dates, and they are never updated. We model actual payment behaviour from your history, place VAT, PAYE, Corporation Tax and Self Assessment payments on their real dates, and offer the refresh retainer so the forecast stays current.
Do I need bookkeeping with you to have a forecast?
No, but the data must exist. We build forecasts from any reasonably kept accounting file plus bank data. If the bookkeeping is behind, we say so first, because a forecast built on stale records is worthless. Clients in our bookkeeping service have the data ready by default.
