Services
What we do for Balham and what it costs
All 26 services below are available to Balham clients at the published fee. Every fee is fixed and confirmed in writing before work starts.
Why IGI
Working with Balham businesses
We built the service around what business owners in places like Balham actually complain about: not knowing what the accountant will charge, finding out about a deadline after it has passed, and receiving a set of accounts with no explanation. Each is fixed by design: fixed fees, deadline tracking shown on every page, and a plain-English summary with every draft for Balham clients.
The output for Balham 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.
Deadline-first: the dates that matter for self assessment tax returns are shown at the top of this page, diarised for every Balham client and chased before they arrive.
One fixed fee for self assessment tax returns in Balham, agreed in writing before any work starts and never changed part-way through the job, however long it takes us.

Worth knowing
Rules that affect most businesses here
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.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
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
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
Questions
Questions from Balham
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 Balham 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 Balham 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.
Do you work with businesses in South London that are not in Balham itself?
Yes. Every place in South 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 Balham 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 Balham: records in, draft out, approve, filed.
How do I get started from Balham?
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 self assessment tax returns. Once you confirm, we tell you exactly which records to send and the work begins. Most Balham clients are set up within a day.
Which deadlines matter most for self assessment tax returns?
The next four dates that apply to self assessment tax returns are shown at the top of this page, calculated from today. For Balham 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.
