Key Accounting Needs for UK Limited Companies
Corporation Tax
Limited companies in the UK are subject to Corporation Tax on their profits. Understanding the rates and ensuring your software can facilitate accurate calculations and filings is paramount.
Corporation Tax Rates (2026/27) [1]
| Rate | 2025 |
|---|---|
| Small Profits Rate (<£50k) | 19% |
| Main Rate (>£250k) | 25% |
| Marginal Relief lower limit | £50,000 |
| Marginal Relief upper limit | £250,000 |
Companies with profits between £50,000 and £250,000 pay tax at the main rate, reduced by marginal relief, leading to a gradual increase in the effective Corporation Tax rate.
CT600 Filing Capability
From 1 April 2026, HMRC will require commercial software for filing annual accounts and Company Tax Returns [2]. This makes it essential to choose software that supports CT600 filing directly or through integration.
Payroll
Managing payroll for a limited company involves adhering to specific National Insurance and statutory payment regulations.
Class 1 National Insurance Thresholds (2026/27) [3]
| Threshold | 2025 to 2026 |
|---|---|
| Lower Earnings Limit (Weekly) | £125 |
| Primary Threshold (Weekly) | £242 |
| Secondary Threshold (Weekly) | £96 |
| Upper Earnings Limit (Weekly) | £967 |
| Employer (secondary) contribution rate (Standard) | 15% |
| Statutory Sick Pay (SSP) weekly rate | £118.75 |
| Employment Allowance | £10,500 |
Companies House Filing
Companies House filing requirements are becoming increasingly digital. While the mandatory software-only filing for annual accounts comes into effect from 1 April 2027, HMRC's mandate for commercial software for CT and accounts filing starts earlier, from 1 April 2026 [4]. Your chosen software should support compliant digital filing.
Directors Loan Account & Dividend Tracking
Tracking directors' loan accounts and dividend payments is crucial for compliance and managing company finances. The software should provide clear mechanisms for recording and reporting these transactions, ensuring proper record-keeping and tax compliance.
Accrual Accounting
Accrual accounting is generally required for limited companies, providing a more accurate picture of financial performance by recording income and expenses when they are incurred, regardless of when cash is exchanged. Ensure your software fully supports accrual accounting principles.
Multi-user Access for Directors & Accountant Collaboration
For limited companies with multiple directors or those working closely with an external accountant, multi-user access and collaboration features are essential. This allows for seamless data sharing and efficient workflow.
