Your Finance Setup in 2026: 6 Things Every New UK Limited Company Needs

It only takes a short online application to incorporate a limited company. The finance and admin that come next, though, are a big step up from life as a sole trader or a side project. The company is its own legal entity, with its own money, tax obligations and filing deadlines with Companies House and HMRC. Directors carry legal duties as well, and when company and personal finances get mixed, tax problems can follow that take time and money to unpick.

Setup is easiest to get right in the first few months, before habits form and transactions pile up. Below are six things every new UK limited company needs in its finance setup, opening with the accounting software at the centre of it all.

1. Sage Accounting: One Place for Books, Invoicing, VAT and Payroll

A new company gets a proper set of books from day one with Sage Accounting. Connecting your business bank account means transactions flow in automatically, with automatic bank reconciliation matching them to your records. Sales invoices can be created and sent, what you are owed can be tracked and customers can pay online through GoCardless and Stripe.

As your company grows, so does Sage Accounting. Once you are registered for VAT, it calculates and submits VAT returns and keeps you Making Tax Digital ready. VAT returns can therefore be submitted to HMRC from your digital records without the figures being manually re-entered. Because Sage Payroll and essential HR features integrate with Sage Accounting, managing payroll alongside your accounting records is straightforward, and Sage Copilot helps with routine admin while highlighting trends in your figures.

2. Pleo: Company Spending Cards and Expense Tracking

Paying for company costs on a personal card, then losing track of what is owed back, is one of the most common problems for new directors. Pleo offers physical and virtual company cards so that business spending comes straight out of the company's money and not yours.

At the point of purchase, receipts are captured on your phone, and each card can have its own spending limit as you add team members. Keeping company and personal spending apart from the outset also prevents confusion over your director's loan account.

3. Hiscox: Protecting the Business With Insurance

Running a limited company protects your personal assets from many business debts, but that does nothing to protect the company itself from claims. Hiscox offers small UK companies business insurance, including professional indemnity, public liability and employers' liability cover, with policies available to buy and manage online.

Once most companies take on staff, employers' liability insurance becomes a legal requirement, and many clients will want to see proof of professional indemnity or public liability cover before signing a contract. Having the right policies early on avoids delays when your first big opportunity arrives.

4. Inform Direct: Keeping Statutory Records and Filing With Companies House

All limited companies must keep statutory registers, such as registers of members, directors and people with significant control, and keep Companies House informed when anything changes. As company secretarial software, Inform Direct holds these records in one place and lets you file changes and confirmation statements with Companies House online.

Reminders for upcoming deadlines help make sure nothing goes in late, and well organised company records from the beginning make bringing in investors, adding shareholders or issuing new shares far easier down the line.

5. Stripe: Accepting Online Payments

Fast payment matters while a new company builds its cash reserves. Stripe lets you take card payments online, via payment links, on your website or for recurring services, and pays the funds into your business bank account.

Strong Customer Authentication is handled for you, and payments in many currencies are supported, which helps if your first customers are overseas. Clear reports of every payment and fee make matching each payout in your accounts easier too.

6. NEST: Auto-Enrolment Pensions for Your First Staff

New duties arrive with your first employee, and workplace pension auto-enrolment is one of them. NEST, the government-backed workplace pension scheme set up to support auto-enrolment, accepts any employer regardless of size, so it is a common choice among new companies.

Where a company's only staff are directors without employment contracts, there are usually no auto-enrolment duties, though you should check The Pensions Regulator's guidance rather than assume every director is exempt. Setting up a scheme ahead of your first payday keeps you on the right side of The Pensions Regulator from the start.

The First Two Years: Key Company Deadlines

A new company faces several deadlines at different points, so it is useful to know what lies ahead.

Within three months of starting to do business: The company must be registered with HMRC for Corporation Tax.

Before your first payday: Register for PAYE as an employer if you will run payroll for yourself or employees and your payroll meets HMRC's registration criteria.

12 months after incorporation: Your first confirmation statement period comes to an end, and Companies House must receive it within 14 days.

21 months after incorporation: This is when your first set of accounts is due at Companies House.

Nine months and one day after your accounting period ends: Any Corporation Tax due is payable, while the Company Tax Return itself is due 12 months after the period ends.

Common Questions

Can Sage Accounting be used to run payroll for me as a director?

Yes. Using Sage Payroll alongside Sage Accounting means you can pay yourself and your first employees from the same system as your books. Your circumstances determine the right balance of salary and dividends, so agreeing it with your accountant is worthwhile.

Is a separate company card something I really need?

It makes life much easier. Paying company costs out of company funds keeps your records clean and stops lots of small amounts building up on your director's loan account, which your accountant would otherwise have to unpick.

Where should our statutory registers be kept?

In a secure place that is easy to update whenever something changes, such as when a new director or shareholder joins. Company secretarial software stores the registers with your filing history and sends reminders of upcoming deadlines.

When is the right time to set up VAT in our accounting software?

As soon as you have registered for VAT, either voluntarily or because your taxable turnover passed the threshold. Sage Accounting can then calculate and submit VAT returns under Making Tax Digital from your records.
