Start-Ups

Start your business on the right foot

From your very first invoice to your first hire, we'll get your structure right, your compliance calendar sorted, and your numbers ready for whoever needs to see them.

A start-up accountant helps you launch on solid foundations: choosing between sole trader and limited company, registering with HMRC and Companies House, setting up cloud bookkeeping, and mapping your first-year deadlines. We do all of that, so you can spend your energy building the business, not decoding tax rules.

The plain-English promise

Big idea, solid foundations

Starting out is exciting, and a little daunting. There's a company to form, a bank account to open, HMRC to register with, and a fog of rules about what you can claim and when things are due. Get the foundations right now and you'll save yourself a world of untangling later.

We sit down with you before the paperwork starts. Should you trade as a sole trader or set up a limited company? What's the smartest way to draw money out? Which cloud software fits how you actually work? We answer all of it in plain English, then set everything up properly the first time.

From there you get a clear first-year calendar, books that are always up to date, and accounts tidy enough to put in front of a lender or investor. No guesswork, no missed deadlines — just a business built to grow.

Is this you?

Sound like where you are?

  • You're not sure whether to be a sole trader or a limited company.
  • You don't know which taxes you'll owe, or when they're due.
  • You're keeping receipts in a shoebox and hoping for the best.
  • You need proper accounts to apply for funding or a business loan.
  • You want cloud software set up, but don't know where to start.
  • You'd love one person who can just tell you what to do next.

Every one of those has a simple answer — and getting them sorted early is exactly what we're here for.

How it works

From idea to trading in three steps

  1. We map your launch

    A relaxed first chat about your idea, your goals and your budget, so we can recommend the right structure and setup.

  2. We set you up properly

    Formation, registrations, cloud software and your compliance calendar — all handled and explained, nothing left half-done.

  3. We keep you on track

    Ongoing support, tidy books and a friendly nudge before every deadline, so you can focus on the business itself.

Your first-year deadlines to know

If you register as self-employed, tell HMRC by 5 October after the tax year you started, and file your first Self Assessment by 31 January. A new limited company files its first accounts 21 months after incorporation, with corporation tax due 9 months and 1 day after its year-end. We track every one of these for you.

I came to them with an idea and a laptop, and left with a limited company, Xero set up, and a calendar I actually understand. They made the scary part feel easy.

Questions, answered

Start-up questions, answered

It depends on your profits, your appetite for admin, and how much personal protection you want. A limited company can be more tax-efficient once profits grow and keeps your personal finances separate, but it comes with extra filing. We'll run the numbers for your situation and give you a straight recommendation — not a hedge.

If you're self-employed, you must tell HMRC by 5 October following the end of the tax year you started trading. A new limited company is automatically flagged to HMRC on incorporation, but you'll still need to register for corporation tax within three months of starting to trade. We handle these registrations so nothing is missed.

Less than most founders fear. We build a fixed monthly fee around exactly what your young business needs — nothing you don't — so it's predictable and grows only as you do. You'll get a clear quote up front, with no surprise bills.

Absolutely. Lenders and investors want clean, credible figures they can trust in minutes. We keep your books accurate in real time and can prepare management accounts, forecasts and projections that stand up to scrutiny — the sort of numbers that get a "yes".

In our clients' words

Relationships that outlast the tax year

We came to HK Accountax mid-panic before a VAT deadline and left with a plan, a proper system, and a lot less dread. Pankaj explains things without making you feel daft.

Switching over was painless — they sorted everything with our old accountant. Now we actually get told about tax bills in advance instead of the week they're due.

Director, Facilities Company
My self-assessment used to eat a whole weekend. Now I send my figures over and it's done properly, on time, with reliefs I didn't even know I could claim.

Straight-talking, quick to reply, and genuinely on our side. It feels like having a finance person in the family rather than a faceless firm.
M Mark & Lucy P.
Landlords, Buckinghamshire
They set up our company, got us on Xero, and mapped out the whole first-year compliance calendar. Exactly the steady hand a new business needs.
