How it works

Bookkeeping from Thornton Heath, step by step

  1. Tell us your situation

    A short message or call about what you do and what needs filing. We ask the questions that determine the right package and nothing more.

  2. Fixed fee in writing

    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

Why Thornton Heath businesses file with IGI

Deadline-first: the dates that matter for bookkeeping are shown at the top of this page, diarised for every Thornton Heath client and chased before they arrive.

Online only, UK based. There is no office in Thornton Heath to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Continuity matters in bookkeeping: the person who prepared last year's work for your Thornton Heath business prepares this year's, and remembers what was agreed.

The output for Thornton Heath clients is never just a form. It is the form, a one-page summary of what it says, and a note of the decisions it points to for bookkeeping.

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.

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.

Late filing penalties

Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.

Making Tax Digital for Income Tax

MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.

The Self Assessment calendar

Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.

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.

Salary versus dividends

Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.

Questions

Bookkeeping questions from Thornton Heath

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.

Will I need this for Making Tax Digital for Income Tax?

If you are a sole trader or landlord with qualifying income over £50,000 you joined MTD for Income Tax in April 2026, and the £30,000 threshold follows in April 2027. It requires digital records and quarterly updates to HMRC. Our bookkeeping service keeps the records in the required form and submits the updates.

How do you handle cash sales and personal spending from the business account?

Cash takings are recorded from your till or daily summary, and personal spending is coded to drawings or the director's loan account so it does not end up as a business expense. We flag patterns that could cause problems, such as a growing director's loan balance.

Can you catch up a backlog?

Yes. Backlogs are quoted as a fixed fee based on the number of months and transactions, agreed before we start. Once caught up, the normal monthly band applies. We tell you honestly if the backlog is small enough to do yourself.

What is the VAT bundle?

Bookkeeping plus quarterly VAT returns for £119 a month, covering up to 150 transactions. Because we already have the coded transactions, the return is prepared and submitted through MTD-compatible software without extra data entry, and you approve it before anything goes to HMRC.

Do you have an office in Thornton Heath?

No. IGI Accounting is an online-only firm. We serve Thornton Heath and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for bookkeeping is the same in Thornton Heath as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is bookkeeping in Thornton Heath really the same price as elsewhere?

Yes. The fee published on this page is what a client in Thornton Heath pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
