Worth knowing

Rules that come up in this work

Switching accountants

You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.

Closing a company

Striking off a company is cheap but must be done in order: stop trading, file the final accounts and CT600, pay the tax, close VAT and PAYE, distribute the remaining assets, close the bank account, then apply. Anything left in the company at dissolution passes to the Crown. Distributions up to £25,000 are taxed as capital gains; above that a formal liquidation is usually needed to keep capital treatment.

Crypto records and reporting

Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.

The 60-day property CGT return

Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.

Record keeping

Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.

Allowable expenses

The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.

Employer National Insurance

Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.

Questions

Cash-Flow Forecasting questions from City of Westminster

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.

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.

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 City of Westminster 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.
