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
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
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
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 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.
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.
Questions
Cash-Flow Forecasting questions from Brockley
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.
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.
