Worth knowing

Rules that come up in this work

The 60-day property CGT return

The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.

Crypto records and reporting

Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.

Allowable expenses

An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.

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.

Workplace pensions and auto-enrolment

Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.

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.

The trading and property allowances

Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.

Questions

Cash-Flow Forecasting questions from Southampton

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.

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.

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.

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.

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.

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.
