Packages for limited companies and growing SMEs start from £85pm+, depending on the support your business needs.

If you run a growing company, tax should not only be considered when a deadline is approaching. Good small business tax services help you keep accurate records, understand your numbers and plan for bills before they become a cash-flow problem.

This simple guide explains the main tax responsibilities for UK limited companies in 2026, what an accountant can do for you and how to choose the right support.

Which taxes does a UK limited company need to manage?

A limited company is legally separate from its owners and directors. This means the company has its own records, filing responsibilities and tax obligations.

Depending on your business, you may need to manage:

• Corporation Tax on company profits

• VAT, if your company is registered or needs to register

• PAYE and National Insurance for directors and employees

• Payroll and workplace pension duties

• Statutory company accounts

• Companies House filings

• Personal Self Assessment for some directors

• Making Tax Digital requirements where relevant

Your exact responsibilities depend on your turnover, profit, number of employees, accounting year-end and company structure.

Corporation Tax in 2026

Corporation Tax is charged on a company’s taxable profits after allowable expenses, adjustments and reliefs have been considered.

For Corporation Tax years beginning in 2026, HMRC confirms:

• Companies with profits of £50,000 or less may qualify for the 19% small profits rate

• Companies with profits above £250,000 generally pay the 25% main rate

• Companies with profits between £50,000 and £250,000 may receive marginal relief, creating an effective rate between 19% and 25%

These limits can be affected by associated companies and shorter accounting periods, so the headline rates do not always tell you exactly what your business will pay.

Your accountant can help by:

• Preparing your Corporation Tax calculation

• Reviewing allowable business expenses

• Checking whether marginal relief applies

• Considering capital purchases and available allowances

• Preparing and filing the CT600 return

• Calculating when your Corporation Tax payment is due

• Helping you set money aside for the tax bill

A company tax return is normally filed within 12 months of the end of the accounting period. Corporation Tax is usually payable nine months and one day after the end of the accounting period.

You can check the latest rules on Corporation Tax rates and allowances on GOV.UK.

VAT: keep an eye on the £90,000 threshold

VAT can become a major responsibility as your company grows.

You normally need to register for VAT if your taxable turnover for the previous 12 months goes above £90,000. You may also need to register if you expect your taxable turnover to exceed £90,000 in the next 30 days.

The test is based on a rolling 12-month period. It is not based only on your financial year, calendar year or VAT quarter. This means you should review your turnover regularly, particularly if sales are increasing quickly.

Once registered, your company will usually need to:

• Charge the correct rate of VAT

• Keep suitable digital VAT records

• Submit VAT returns on time

• Pay VAT owed to HMRC

• Reconcile VAT collected with VAT paid on business purchases

• Use compatible software under Making Tax Digital for VAT

Late registration can create an unexpected liability because you may need to account for VAT on sales made before you realised registration was required.

Read the official VAT registration guidance on GOV.UK, or ask an accountant to review your sales forecasts and VAT position.

Making Tax Digital and digital records

Making Tax Digital has already changed the way VAT-registered businesses keep records and file returns. In 2026, limited companies should have reliable digital bookkeeping processes in place.

This does not mean every company has to submit quarterly Corporation Tax updates. However, digital records make it easier to:

• Track income and expenses

• Reconcile your business bank account

• Prepare VAT returns

• Monitor profit margins

• Identify unpaid invoices

• Share information securely with your accountant

• Prepare year-end accounts

Making Tax Digital for Income Tax mainly affects sole traders and landlords rather than company profits. However, it may affect a company director who also has separate self-employed income or property income.

HMRC’s current timetable says individuals with qualifying income above £50,000 should use Making Tax Digital for Income Tax from 6 April 2026. The threshold is due to reduce to £30,000 from April 2027 and £20,000 from April 2028. You can check the rules using the HMRC Making Tax Digital guidance.

What should small business tax services include?

A basic year-end service may be suitable for a straightforward company with few transactions. A growing SME often needs more regular support.

Bookkeeping and monthly reporting

Up-to-date bookkeeping shows what is happening inside your business. It can help you see whether sales are increasing, which customers owe money and where costs are rising.

Monthly or quarterly bookkeeping also reduces the pressure at year-end. Your accountant can work from current records rather than sorting through a large backlog of receipts and invoices.

Year-end accounts and Corporation Tax

Your accountant can prepare your statutory accounts, submit the required information and complete your Corporation Tax return.

A good service should also explain the figures in plain English. You should understand your profit, tax bill, cash position and any issues that need attention.

VAT returns

If your company is VAT-registered, an accountant may prepare and submit your VAT returns. They can also help you review VAT treatment, maintain digital records and choose suitable software.

Payroll and pensions

Once you employ staff, payroll becomes a regular monthly responsibility. Support may include:

• Payslips

• PAYE reporting

• National Insurance calculations

• Director payroll

• Workplace pension administration

• Year-end payroll information

Director tax support

Your company’s tax return is separate from your personal tax return.

A director may need to complete Self Assessment because of dividends, property income, savings, benefits or other income not fully dealt with through PAYE. This is why some company directors search for tax returns for self employed, even though their main business operates through a limited company.

A Self Assessment accountant can help you report personal income correctly. The company’s Corporation Tax and your personal Self Assessment are connected, but they are not the same return.

How much does an accountant cost in 2026?

There is no single price for accounting services for SMEs. Fees depend on:

• The number of transactions

• Whether you are VAT-registered

• The number of employees

• Whether bookkeeping is included

• The complexity of your company structure

• Whether you need monthly advice

• Whether you require management accounts or forecasting

For a straightforward limited company, packages may start from £85pm+. More involved businesses with VAT, payroll, regular bookkeeping or tax planning will usually pay more.

When comparing quotes, ask whether the monthly fee includes:

1. Bookkeeping

2. Year-end accounts

3. Corporation Tax filing

4. Companies House filing support

5. VAT returns

6. Payroll

7. Director Self Assessment

8. Tax planning and advice

A lower monthly fee may not be cheaper if important services are charged separately.

Local accountants near me or online support?

Many business owners search for local accountants near me because they want face-to-face meetings and a professional who understands their area.

A local accountant may suit you if:

• You prefer in-person meetings

• Your business operates from premises

• You want a long-term local relationship

• You need help with local staff or expansion

• You value regular personal contact

Online accounting can also work well for growing SMEs. Cloud bookkeeping, video meetings and secure document sharing mean your accountant does not always need to be in the same town.

The most important factors are usually:

• Experience with limited companies

• Clear communication

• Transparent pricing

• Reliable response times

• Knowledge of your industry

• A service that can grow with your company

You can find an accountant through Accountant Search, or explore support from a limited company accountant.

Final thoughts

Tax becomes easier to manage when it forms part of your normal business routine. Waiting until the end of the year can lead to rushed decisions, missed reliefs and avoidable cash-flow pressure.

For a limited company or growing SME, the right accountant can support much more than tax returns. They can help you manage Corporation Tax, prepare VAT returns, run payroll, keep digital records and understand the numbers behind your growth.

Start by comparing the support your business needs today with the support it may need over the next 12 months. Then choose an accountant who offers clear advice, transparent pricing and experience with growing limited companies.
