Worth knowing
Rules that come up in this work
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.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The trading and property allowances
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
Questions
Making Tax Digital questions from Mortlake
What if my income drops below the threshold later?
Once in MTD you stay in unless your qualifying income falls below the threshold for three consecutive years, after which you can apply to leave. There are exemptions for digital exclusion on grounds of age, disability, location or religion, which must be applied for and granted by HMRC.
How does MTD for VAT differ?
MTD for VAT has applied to all VAT-registered businesses since April 2022: digital records and returns submitted through compatible software, with the same quarterly return as before. If you are still typing figures into a portal or using software that is not linked, you are non-compliant. Our £129 setup includes the first return filed.
What does the £99 readiness check and setup include?
Confirmation of your start date, choice and setup of MTD-compatible software suited to your business, bank feeds connected, the chart of categories mapped to HMRC's reporting lines, the authorisation of the software with HMRC, and a short walkthrough so you know how to capture receipts and invoices day to day.
Can I keep using my spreadsheet?
Only with bridging software that links the spreadsheet digitally to HMRC, and the links must be digital, not copy-and-paste. For VAT this remains workable; for Income Tax the quarterly category reporting makes proper software far less effort. We set up whichever approach suits you and explain the trade-off honestly.
When does Making Tax Digital for Income Tax apply to me?
It depends on your gross self-employment plus property income on your 2024/25 return: over £50,000 means you joined from 6 April 2026; over £30,000 means 6 April 2027; over £20,000 is planned for April 2028. Below £20,000 there is currently no requirement. We check your figures and confirm the date in writing.
What do I actually have to do under MTD for Income Tax?
Keep records of income and expenses digitally in compatible software, send HMRC a quarterly update summarising them by 7 August, 7 November, 7 February and 7 May, and submit a final declaration with any adjustments and other income by 31 January. The tax payment dates are unchanged.
Do you have an office in Mortlake?
No. IGI Accounting is an online-only firm. We serve Mortlake 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 making tax digital is the same in Mortlake as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is making tax digital in Mortlake really the same price as elsewhere?
Yes. The fee published on this page is what a client in Mortlake 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.
