New UK Limited Companies in 2026: 6 Things Every Finance Setup Needs
Incorporation is a short online application, but what follows on the finance and admin side is a big step up from life as a sole trader or a side project. Companies are separate legal entities with their own money, their own tax obligations and their own Companies House and HMRC filing deadlines. Legal duties apply to directors too, and mixing company money with personal money can create tax problems that take time and money to unpick.
Before transactions pile up and habits form, the first few months are the easiest time to get things set up properly. Here are six things every new UK limited company needs in its finance setup, starting with the accounting software that sits at the centre of it all.
1. Sage Accounting: Your Books, Invoices, VAT and Payroll in One System
Sage Accounting provides a new company with a proper set of books from the very first day. When you connect your business bank account, transactions flow in automatically and are matched against your records through automatic bank reconciliation. You can also create and send sales invoices, track what you are owed and allow customers to pay online through GoCardless and Stripe.
Sage Accounting expands as the company does. When you register for VAT, it will calculate and submit your VAT returns and keep you Making Tax Digital ready, so VAT returns can be submitted to HMRC from your digital records with no need to manually re-enter the figures. Sage Payroll and essential HR features integrate with Sage Accounting, so payroll is straightforward to manage alongside your accounting records, and Sage Copilot helps with routine admin as well as highlighting trends in your figures.
2. Hiscox: Insuring Your New Company
Running a limited company protects your personal assets from many business debts, but it offers the company itself no protection from claims. Business insurance from Hiscox for small UK companies includes professional indemnity, public liability and employers' liability cover, and policies can be bought and managed online.
Most companies are legally required to hold employers' liability insurance once they take on staff, and before signing a contract, many clients will ask for proof of professional indemnity or public liability cover. With the right policies in place early, your first big opportunity is not held up by delays.
3. NEST: Auto-Enrolment for Your First Employees
Workplace pension auto-enrolment is one of the new duties that come with taking on your first employee. NEST is the government-backed workplace pension scheme set up to support auto-enrolment, and because it accepts any employer regardless of size, new companies commonly choose it.
If a company's only staff are directors who have no employment contracts, it usually has no auto-enrolment duties. Still, check The Pensions Regulator's guidance instead of assuming that every director is exempt. Putting a scheme in place before your first payday keeps you on the right side of The Pensions Regulator from the outset.
4. Pleo: Managing Company Cards and Expenses
Among the most common problems new directors face is paying company costs on a personal card and losing track of what they are owed back. Pleo provides company cards in physical and virtual form, meaning business spending comes directly from company money rather than from yours.
Receipts can be captured by phone at the point of purchase, and as you add team members, you can set spending limits per card. Keeping company and personal spending separate from the outset also heads off confusion over your director's loan account.
5. Inform Direct: Companies House Compliance and Statutory Registers
Each limited company must maintain statutory registers, among them registers of members, directors and people with significant control, and must keep Companies House up to date whenever something changes. Inform Direct, company secretarial software, keeps these records in one place and allows changes and confirmation statements to be filed with Companies House online.
Reminders of upcoming deadlines help ensure nothing is filed late. Organising your company records from the start also makes it far easier to bring in investors, add shareholders or issue new shares in future.
6. Stripe: Online Card Payments
For a new company building its cash reserves, getting paid quickly matters. Stripe allows you to accept card payments online through payment links, on your website or for recurring services, with funds landing in your business bank account.
It takes care of Strong Customer Authentication and supports payments in many currencies, a helpful feature should your first customers be overseas. Matching each payout in your accounts is also simpler because of clear reports on every payment and fee.
Your Company's Key Deadlines in Years One and Two
There are several deadlines for a new company, each falling at a different point, so knowing what is coming is helpful.
Within three months of starting to do business: You need to register the company for Corporation Tax with HMRC.
Before your first payday: Register as an employer for PAYE when you will run payroll for yourself or employees and your payroll meets HMRC's registration criteria.
12 months after incorporation: This is when your first confirmation statement period ends, after which you have 14 days to file it with Companies House.
21 months after incorporation: Your first set of accounts needs to be filed with Companies House.
Nine months and one day after your accounting period ends: Any Corporation Tax due has to be paid, and the Company Tax Return itself is due 12 months after the period ends.
Questions New Company Directors Often Ask
Is it possible to run my own director's payroll in Sage Accounting?
Yes. Sage Payroll can be used with Sage Accounting, which means you and your first employees can be paid from the same system as your books. As the right balance of salary and dividends depends on your circumstances, it is worth agreeing with your accountant.
Do I actually need a separate company card?
It makes life much easier. Using company funds for company costs keeps your records clean and avoids an accumulation of small amounts on your director's loan account, which would otherwise need unpicking by your accountant.
What is the best place for our statutory registers?
Somewhere secure that is simple to update whenever something changes, such as the arrival of a new director or shareholder. Company secretarial software keeps the registers together with your filing history and reminds you as deadlines approach.
At what stage should VAT be set up in our accounting software?
As soon as your VAT registration happens, whether it was voluntary or because taxable turnover passed the threshold. Sage Accounting can then use your records to calculate and submit VAT returns under Making Tax Digital.
