Business solvency refers to a company’s ability to meet its financial obligations as they fall due and to maintain a healthy balance between its assets and liabilities. It is one of the key indicators of financial stability and is essential for the long term survival of any business.

A solvent business has sufficient resources to pay suppliers, employees, lenders and the tax authorities on time. Maintaining this position helps to build trust with stakeholders. Suppliers may be more willing to offer favourable credit terms, lenders may be more comfortable providing finance, and customers are more likely to have confidence in a business that appears financially stable.

Solvency is also important from a legal and governance perspective. Company directors have a duty to ensure that their business does not continue trading if it is unable to meet its obligations. If a company trades while insolvent, directors could face serious consequences, including potential personal liability for certain debts.

Regular financial monitoring plays an important role in protecting solvency. Reviewing management accounts, balance sheets and cash flow forecasts allows business owners to identify potential problems early. This may provide time to reduce costs, improve collections from customers, refinance borrowings or introduce additional capital.

Maintaining adequate reserves and controlling debt levels are also key elements of a strong solvency position. Businesses that rely too heavily on borrowing can become vulnerable if trading conditions deteriorate or interest rates rise.

For these reasons, solvency should be seen as a core measure of business health. Regular financial review and forward planning can help ensure that a business remains stable, resilient and able to meet its commitments.

After the end of its financial year, a private limited company must prepare full annual accounts and submit a company tax return. In most cases, the tax return must be filed within 12 months of the end of the accounting period it covers, and filing must be completed online.

There are penalties for the late submission of company tax returns. The filing penalties will increase for company tax returns where the filing date falls on or after 1 April 2026.

The penalties are designed to encourage companies to file their Corporation Tax returns by the required deadline. Fixed penalties for late filing were originally set in 1998 and have remained unchanged since then. Over time, inflation has significantly reduced the real value of these penalties and therefore their deterrent effect. In real terms, the penalties are now worth roughly half of what they were when first introduced.

The increase in company late filing penalties has seen the doubling of fixed penalties. Since 1 April 2026, a return that is filed late will attract a penalty of £200 instead of £100. If the return is more than three months late, the penalty is now £400, compared with the previous £200. Higher penalties will continue to apply where a company repeatedly files late returns. Where there are three successive failures to file on time, the penalty will be £1,000, and where the return is more than three months late after three consecutive failures, the penalty will be £2,000.

Ensuring that company tax returns are submitted on time will help companies avoid unnecessary penalties and additional compliance costs.

A number of changes to the taxation of dividends, property income and savings income were announced in the Autumn Budget 2025. These measures will affect the rates at which different types of income are taxed and will be introduced in stages over the next few years.

From April 2026, the tax rates applying to dividend income will increase by 2%. The ordinary dividend rate will be 10.75%, while the upper dividend rate will increase to 35.75%. The dividend additional rate and the dividend trust rate will remain unchanged at 39.35% as will the dividend allowance at £500.

Further changes will apply from April 2027. Income Tax rates on both property income and savings income will increase by 2%. For the 2027–28 tax year, property income will be taxed at 22% (basic rate), 42% (higher rate) and 47% (additional rate). Savings income will also be taxed at the same rates.

Alongside these rate changes, the government is also reforming how Income Tax is calculated by altering the current ordering rules that determine the calculation of Income Tax. Under the current system, savings and dividend income are treated as the highest part of an individual’s income. Most other income, such as employment, pension or trading income, is grouped together as “non-savings, non-dividend income” and taxed first.

Under the new rules, the revised order of taxation will be:

1. Income that is not property, savings or dividend income
2. Property income
3. Savings income
4. Dividend income

These changes to the calculation of Income Tax are intended to better reflect the different nature of income sources and ensure the new tax rates for property, savings and dividends operate as intended.

It was confirmed as part of the Autumn Budget that the Income Tax thresholds will continue at their current levels for a further three years, extending the freeze until April 2031. This means that most tax allowances are to remain frozen for 2026-27 and beyond.

As a result, the personal allowance will stay at £12,570, while the higher rate threshold will remain at £50,270 for taxpayers across most of the UK (with different thresholds applying in Scotland). National Insurance thresholds will also remain fixed over the same period.

Keeping these thresholds unchanged means that many taxpayers will gradually pay more tax as their earnings increase over time. This effect, commonly known as fiscal drag, occurs when wages rise but tax bands do not. As incomes grow due to inflation or pay increases, a larger portion of earnings becomes taxable, and more people move into higher tax brackets.

In practical terms, the continued freeze is likely to push increasing numbers of taxpayers into the 40% higher rate band and, for some, the 45% additional rate band. Others who previously earned below the personal allowance may also begin paying Income Tax for the first time. Although tax rates themselves remain unchanged, the overall tax burden rises as more income becomes subject to tax.

Fiscal drag is influenced by several factors, including government policy on tax thresholds, inflation levels and wage growth. In periods of rising wages or high inflation, the impact of frozen thresholds becomes more pronounced. For taxpayers the impact of fiscal drag effectively operates as a stealth tax over time.
