For a startup, an accountant does four things: helps you choose the right structure before you commit to one, sets up the registrations and record-keeping so the business starts compliant, puts numbers on your plans through first forecasts, and steers you through the first-year calendar of obligations you have never met before. Startups get disproportionate value from early accounting input for a simple reason: the first month’s decisions (structure, shares, record habits) are nearly free to get right and genuinely expensive to unwind. Founders usually call an accountant at their first year end. The better time is before the business exists.
The structure decision
The first fork is sole trader or limited company, and it deserves an evidence-based answer rather than a default. GOV.UK describes both routes. Setting up as a sole trader is nearly instant; forming a company is quick but brings statutory obligations from day one.
An accountant weighs your expected profits, whether you will reinvest or draw everything, who your customers are and what they expect, funding plans, risk, and how much administration you will tolerate. Neither answer is universally right. Starting as a sole trader and incorporating later is a perfectly good path for many; starting as a company matters for others, particularly where investors or certain contracts are involved. What an accountant prevents is the unconsidered choice: the company formed because a friend said so, now generating filing obligations a simpler structure would have avoided, or the sole trade that should have been a company before signing its first big contract. If the answer is a company, the setup work is covered in how an accountant helps with company formation.
Registrations and record-keeping from day one
Whichever structure wins, a short list of setup tasks follows: registering with HMRC on the right timetable, a business bank account so business and personal money never mix, and record-keeping that starts correct rather than getting corrected later. GOV.UK sets out what records a business must keep, and the startup habit worth building is capturing income and expenses digitally as they happen.
Two startup-specific points earn their place here. Costs you incur before trading starts can often be claimed once it does, but only if you kept the evidence, so the receipts from the setup phase matter. And founders who fund early costs personally need those flows recorded properly from the start, because untangling founder money from business money after a year of informality is miserable, and with a company it is more than miserable, because the company’s money is legally not yours.
First forecasts: putting numbers on the plan
Startups run on assumptions, and an accountant’s job is to turn them into arithmetic before reality does. A first-year forecast answers the questions that decide survival: how much cash does the business need before it sustains itself, when does money run lowest, what must sales reach to cover costs, and what happens if revenue lands slower than hoped, which it usually does.
This is the same discipline described in how an accountant helps with a business plan, applied at the stage where it matters most, because startups have no reserves to absorb forecasting errors. If you are seeking funding, the forecast is also the document lenders and investors interrogate. A founder who knows their numbers cold is taken more seriously in every room.
Surviving the first-year calendar
A startup’s first year contains a series of firsts: first tax registration deadlines, first filings, first tax bill, each arriving on a timetable the founder has never experienced. The pattern that hurts is consistent: the first-year tax bill lands after the money that should have paid it has been spent, sometimes accompanied by payments on account towards year two that nobody warned the founder about.
An accountant replaces surprises with a calendar: what is due, when, and how much to set aside from each month’s income so the bill is boring when it arrives. Current deadlines and thresholds are on GOV.UK. Along the way they watch for the thresholds a growing startup crosses (VAT registration on its rolling turnover test, first hires and payroll) so each transition is planned rather than discovered. The ongoing relationship this grows into is described in what an accountant does for a small business.
Frequently asked questions
When should a startup first talk to an accountant?
Before choosing a structure, which means before registering anything. Most firms offer an initial conversation at little or no cost, and an hour before you start prevents the errors that cost real money to unwind later.
Can I do my own accounts in the first year to save money?
You can, and with simple sole trader affairs it may be fine. The riskier saving is skipping the setup advice: structure, registrations and record habits. Many founders take early advice, run their own books, and hand over at year end, which is a sensible middle path.
What does an accountant need from a brand-new business?
At the start: your plans, expected income and costs, and how you will fund the gap. Once trading: the same records as any business (bank statements, income, expenses), listed in what information an accountant needs.
Do startups pay less for accountancy than established businesses?
Generally yes, because there is less history and lower volume. Fees scale with transactions and complexity, so a startup’s first year is usually the cheapest it will ever be. That is one more reason to start records properly while it is easy.
What if the startup does not work out?
Wind-down has its own obligations: final returns, deregistrations, and for companies a formal closing process. An accountant makes the ending clean, which matters for your credit position and for whatever you start next. It is a routine conversation; have it early rather than letting filings lapse.
