Accounting software setup & support in Merton

Most accounting software problems in Merton businesses were created on day one: a default chart of accounts that fits nobody, bank feeds half connected, VAT codes wrong, opening balances never entered. We set it up properly, or fix the one you have, for a one-off fixed fee, and we recommend software on merit rather than commission.

    We find out what you need filed, when it is due and what state the records are in, and tell you which fixed-fee package applies.

Worth knowing

Rules that come up in this work

CIS deductions

Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.

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.

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.

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.

Making Tax Digital for Income Tax

The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.

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.

Corporation Tax rates and marginal relief

Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.

Questions

Accounting Software Support questions from Merton

Do I need Making Tax Digital-compatible software?

If you are VAT registered, yes, already. If you are a sole trader or landlord with qualifying income over £50,000, yes, since April 2026, with lower thresholds following. Every platform we set up is MTD-compatible and we authorise it with HMRC as part of the setup.

How long does setup or migration take?

A new setup is usually complete within three working days of receiving your details and last accounts. A migration takes one to two weeks depending on the volume of history and the state of the old data. A cleanup depends on how broken the file is, and we give you a timeline with the fixed quote.

Can you connect my online shop or payment processor?

Yes. Marketplace and e-commerce platforms, card processors and payment gateways can be integrated so that sales, fees and payouts post automatically and reconcile to the bank. Getting the fee and VAT treatment right on these integrations is where most e-commerce files go wrong, and we configure it as part of the setup.

Will the setup make my year-end cheaper?

Usually, yes. Our own limited company and sole trader accounts fees assume reconciled records, and a properly set up file produces them. Accounts prepared from a tidy software file take days; accounts rebuilt from a broken one take weeks and cost more. The setup fee is typically recovered in the first year-end.

Do you provide training?

Yes. The £89 session is 90 minutes by video call, recorded for you to replay, covering the tasks you actually do: raising invoices, capturing receipts, matching bank transactions, running the VAT return, reading the reports. A written quick-reference follows. Several staff can attend the same session.

Who pays for the software subscription?

You do, directly to the software company, so that the data is yours and you can change accountant without losing it. Subscriptions range from a few pounds a month for basic sole trader tools to around £35 for the fuller platforms. We will tell you if a cheaper tier is sufficient.

How do I get started from Merton?

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 accounting software support. Once you confirm, we tell you exactly which records to send and the work begins. Most Merton clients are set up within a day.

Which deadlines matter most for accounting software support?

The next four dates that apply to accounting software support are shown at the top of this page, calculated from today. For Merton 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.
