Worth knowing

Rules that come up in this work

Crypto records and reporting

HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.

The 60-day property CGT return

Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.

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.

Employer National Insurance

The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.

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.

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.

Questions

Making Tax Digital questions from Trinity

What is the full MTD service?

From £299 a year: software subscription guidance, digital record review each quarter, the four quarterly updates submitted, and the year-end final declaration prepared and filed with capital allowances, adjustments and all other income included. It replaces the traditional Self Assessment fee for clients in MTD. Bookkeeping can be added if you would rather not do the recording.

Can I do MTD myself without an accountant?

Yes, if you are comfortable keeping the records digitally and submitting four updates and a declaration each year on time. Many sole traders do. The value we add is in the setup being right, the categories mapping correctly to HMRC's lines, the deadlines never being missed and the year-end declaration including the adjustments and allowances that reduce your tax.

What are the penalties under MTD?

A points-based system: one point for each late quarterly update or declaration, and a £200 penalty once you reach four points, with the count resetting after a period of compliance. Late payment penalties start at 3% after 15 days. The first year has been described by HMRC as light-touch, but points still accrue.

I am a landlord with a job. Does MTD apply to my rental income?

Yes, if your gross rental income, added to any self-employment income, exceeds the threshold for your start year. Employment income does not count towards the threshold but is reported in the final declaration. Jointly owned property has simplified rules allowing the income-only reporting of your share each quarter.

What is in a quarterly update?

Totals of income and expenses for the quarter by category, taken straight from the digital records. No accounting adjustments, no tax calculation and no payment. The updates are cumulative, so an error in one quarter is corrected in the next. From £35 a quarter we prepare, review and submit each one from your records.

Does MTD change when I pay tax?

No. Payments on account remain due on 31 January and 31 July, and the balancing payment on 31 January after the tax year. HMRC shows an estimated liability after each quarterly update, which is useful for setting money aside, but it is not a demand.

Do you have an office in Trinity?

No. IGI Accounting is an online-only firm. We serve Trinity, Merton 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 Trinity as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is making tax digital in Trinity really the same price as elsewhere?

Yes. The fee published on this page is what a client in Trinity, Merton 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.
