Worth knowing
Rules that come up in this work
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
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.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
The VAT registration threshold
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
Questions
Startup Accountants questions from Southwark
Can I switch to you from another accountant mid-year?
Yes. We request your records and professional clearance from the previous firm, pick up the bookkeeping where they left off and take over the filings. There is no charge for the switch and the first month's fee is the same as any other.
What if the startup fails?
Then the company needs to be closed properly: final accounts, final CT600, deregistration from VAT and PAYE, and a strike-off application or, if there are debts it cannot pay, a formal insolvency process. Our strike-off service with final accounts is from £349. SEIS investors can claim loss relief, which softens their outcome.
Do I need a separate business bank account?
Legally the company must have its own account because it is a separate person from you; using a personal account mixes funds and creates director's loan problems. Digital business banks open accounts quickly for new companies, and we connect the feed to your software as part of setup.
What do investors expect to see in the accounts?
Clean, current bookkeeping; a cap table that matches Companies House; founder payments properly documented; VAT and PAYE up to date; and management accounts showing runway. Due diligence on a seed round routinely finds undocumented director's loans and unfiled confirmation statements, both of which cost time at exactly the wrong moment.
When are a new company's first filings due?
The first confirmation statement is due within 14 days of the first anniversary of incorporation. The first accounts are due 21 months after incorporation. Corporation Tax is due nine months and one day after the first accounting period ends, and the first period is often longer than a year, which creates two CT600s. We handle the split.
Can I claim startup costs incurred before incorporation?
Yes. Pre-trading expenses incurred up to seven years before the company started trading, which would have been deductible if incurred while trading, are treated as incurred on the first day of trading. Keep the receipts. Equipment you bring in can be transferred to the company at market value.
Do you have an office in Southwark?
No. IGI Accounting is an online-only firm. We serve Southwark 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 startup accountants is the same in Southwark as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is startup accountants in Southwark really the same price as elsewhere?
Yes. The fee published on this page is what a client in Southwark 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.
