The fee you see is confirmed in writing before work starts. The dates you see are diarised and chased. And the person who prepares your first return is the person who prepares the next one.
Approval before filing is a rule, not a courtesy. For self assessment tax returns in South Twickenham, every submission to HMRC or Companies House follows your written go-ahead.
The output for South Twickenham 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 self assessment tax returns.
A named person handles your self assessment tax returns from South Twickenham and knows the file, so you are not re-explaining your business to a different helpdesk each time.

Rules that affect most businesses here
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.
Record keeping
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
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 trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Questions
Questions from South Twickenham
Do you work with businesses in South West London that are not in South Twickenham itself?
Yes. Every place in South West London has its own page on this site and the same fees apply throughout. The nearest-places list on this page links to them. Wherever in England your business is based, the service is identical because none of it depends on where you are.
What if my South Twickenham business is a partnership or an LLP?
Both are covered. Partnerships need a partnership return and a Self Assessment for each partner; LLPs file accounts with Companies House under company-style rules as well. We quote a fixed fee for the set based on the number of partners or members, and the process is the same as for any other client in South Twickenham: records in, draft out, approve, filed.
Are your fees inclusive of everything?
Our fee covers the work described for the package. Companies House fees, such as £100 to incorporate or £50 for a confirmation statement, are charged separately and passed on at cost. Software subscriptions are in your own name. There is nothing else: no hourly extras, no charge for questions, and no additional year-end invoice for South Twickenham clients on monthly packages.
How quickly do you respond?
In UK working hours, usually within a few hours and always the same working day. Each South Twickenham client has a named contact who knows the file. Outside working hours, WhatsApp and email messages are picked up first thing the next morning. In January and at other peak times we tell you your turnaround when you book rather than leaving you guessing.
Is self assessment tax returns in South Twickenham really the same price as elsewhere?
Yes. The fee published on this page is what a client in South Twickenham 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.
Do you have an office in South Twickenham?
No. IGI Accounting is an online-only firm. We serve South Twickenham 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 self assessment tax returns is the same in South Twickenham as anywhere else in the country, and why there is nothing to visit and nothing to print.
