Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.
Switching accountants
Changing accountant is simpler than most people fear. You authorise the new firm, which writes to the old one for professional clearance and your records; the outgoing accountant must hand over your own documents and usually does within two weeks. The new firm registers as your agent with HMRC and picks up the next filing. There is no need to wait for a year end.
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
Closing a company
A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.
Record keeping
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
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.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Questions
Bookkeeping questions from South Mimms
Do you do bookkeeping for landlords?
Yes. Rental income, agent statements, mortgage interest, repairs and the split between revenue and capital costs are all coded correctly for the property pages of your return. Portfolio landlords usually sit in the £49 or £89 band, and MTD for Income Tax applies to rental income as it does to trading income.
What if my volume changes?
We review the transaction count each quarter. If you move into a higher or lower band we tell you before the next invoice and adjust from the following month. There is no penalty for moving down and no back-charging for a busy month.
Can my existing accountant still do the year end?
Yes. Many clients use us for bookkeeping and another firm for accounts. At year end we hand over a reconciled file with the trial balance, bank reconciliations and supporting documents, in whatever format your accountant prefers.
How quickly are the books up to date?
Bank feeds update daily. We reconcile within five working days of the month end once your receipts are in, so the monthly summary arrives in the first week of the following month. Queries are sent in one message rather than piecemeal.
How do you count transactions for the fee?
Every line on your business bank and card statements for the month, including payments in and out. Transfers between your own accounts are excluded. Up to 50 lines is £49 a month, up to 150 is £89, up to 300 is £149. We check the count from your statements before quoting so the band is right from the start.
Which software do you use and who pays for it?
We work in the main cloud platforms that are compatible with Making Tax Digital and set up the one that suits your business. The subscription is in your name and billed to you by the software company, typically £15 to £35 a month, so you own the data and can leave at any time with your records intact.
Which deadlines matter most for bookkeeping?
The next four dates that apply to bookkeeping are shown at the top of this page, calculated from today. For South Mimms 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.
How do I get started from South Mimms?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for bookkeeping. Once you confirm, we tell you exactly which records to send and the work begins. Most South Mimms clients are set up within a day.
