Worth knowing

Rules that come up in this work

Salary versus dividends

Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.

Director's loan accounts

The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.

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

Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.

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.

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.

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.

Questions

Cash-Flow Forecasting questions from Merton

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.

What does the 12-month forecast add?

The £349 forecast extends the horizon to a year, monthly, with three scenarios: base case, a downside with slower sales or payment, and an upside, so you can see the cash effect of the things that might happen. It includes a profit and loss and balance sheet forecast alongside the cash, and is the basis for the funding pack.

What is the monthly refresh retainer?

For £99 a month we replace each month's forecast with the actual figures, roll the horizon forward, update the assumptions for what has changed and send you the refreshed forecast with a short note on the movements. A forecast that is not refreshed is out of date within weeks; the retainer keeps it live.

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.
