Worth knowing

Rules that come up in this work

Workplace pensions and auto-enrolment

Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.

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

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.

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.

Payments on account

If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.

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

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.

Questions

Accounting Software Support questions from Lee Green

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.

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.

Which software do you recommend?

It depends on your business. Sole traders with simple needs suit the low-cost MTD-compatible platforms; VAT-registered businesses with stock, multiple currencies or e-commerce integrations need one of the major cloud platforms. We recommend on fit and price and we do not take commission, so the advice is not steered by referral income.

What does the £99 setup include?

Creating the file with your business details and financial year, a chart of accounts tailored to your trade, VAT scheme and codes configured, bank and card feeds connected, opening balances entered from your last accounts, invoice template branded, and the software authorised with HMRC for MTD where relevant. You come away ready to use it.

Can you move my history from my old software?

Yes. Migration from £199 brings across customers, suppliers, outstanding invoices and bills, the chart of accounts and historical transactions, typically for the current and previous financial years, with balances reconciled to the old system before it is closed. More history or very large files are quoted before we start.

What is a file cleanup and when do I need one?

When the bank has not reconciled for months, the suspense account has a large balance, there are duplicate transactions or customers, VAT returns in the software do not match what was filed, or the balance sheet contains figures nobody can explain. From £149 we reconcile, correct and document the file so it can be relied on.

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 Lee Green 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.
