How it works

Startup Accountants from Custom House, step by step

  1. Tell us your situation

    A short message or call about what you do and what needs filing. We ask the questions that determine the right package and nothing more.

  2. Fixed fee in writing

    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

What you get in Custom House

No hourly rate and no surprise invoice. Custom House clients know the fee for startup accountants before they send a single document, and it stays fixed.

We work to the HMRC and Companies House calendar, not an appointment diary. Clients in Custom House get reminders at 60, 30 and 7 days before each date that applies to startup accountants.

Online only, UK based. There is no office in Custom House to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Continuity matters in startup accountants: the person who prepared last year's work for your Custom House business prepares this year's, and remembers what was agreed.

Plain English, with the numbers. Every draft for Custom House comes with a short explanation of what the figures mean and what, if anything, you should do about them.

You stay in control of startup accountants: drafts go to Custom House clients first, with the figures explained, and nothing leaves us until you say so.

Worth knowing

Rules that come up in this work

Switching accountants

You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.

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.

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.

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

Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.

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.

Questions

Startup Accountants questions from Custom House

What is SEIS/EIS advance assurance and do I need it?

Investors in qualifying early-stage companies get income tax relief of 50% (SEIS) or 30% (EIS) and capital gains exemptions, which makes raising much easier. Advance assurance is HMRC's confirmation in principle that your company qualifies, and most angel investors insist on it. Our £299 service prepares and submits the application.

What are the SEIS limits?

A company can raise up to £250,000 under SEIS within the first three years of trading, with gross assets under £350,000 and fewer than 25 employees. EIS allows up to £5 million a year and £12 million in total, for companies under seven years old with fewer than 250 employees. Trading activities must qualify; some are excluded.

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.

What does the £59 Launch package include?

Company formation with the Companies House £100 fee passed on separately, Corporation Tax and PAYE registration, a registered office if you want one, cloud software set up, the first confirmation statement and the first set of accounts and CT600 filed. It is for founders who will keep their own books in the early months.

When do I need Grow or Scale?

Grow at £99 adds monthly bookkeeping and quarterly VAT returns, and suits most startups once transactions and VAT registration arrive. Scale at £149 adds payroll for founders and first hires with auto-enrolment, plus quarterly management accounts for the board or investors. You can move between packages at any month end.

Which deadlines matter most for startup accountants?

The next four dates that apply to startup accountants are shown at the top of this page, calculated from today. For Custom House 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.

How do I get started from Custom House?

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 startup accountants. Once you confirm, we tell you exactly which records to send and the work begins. Most Custom House clients are set up within a day.
