What is the Income Tax Provision and How To Calculate it?

In corporate accounting, profit is not as simple as money in minus money out. One of the most important, yet often misunderstood, components of financial statements is the income tax provision.

For UK businesses, getting this right is the difference between a transparent set of accounts and a surprise bill from HM Revenue and Customs (HMRC).

But what exactly is a tax provision, and why does it matter for year-end reporting? This blog explains the concept of income tax provision and its significance for businesses. It also highlights its benefits and how to calculate it.

What is the Income Tax Provision?

An income tax provision is an estimate of the amount of income tax a company expects to pay for a specific period. It is recorded in the financial statements to ensure that tax expenses match income earned during the same period.

Under UK accounting standards, such as FRS 102, companies must record the tax expense in the same period that the related profits are earned.

The tax provision acts as a liability on the balance sheet, representing an estimated liability to HMRC. The final tax liability amount is determined upon filing the tax return and may vary due to timing, adjustments, or new information.

What is a Tax Provision in the UK

Companies in the UK are subject to Corporation Tax, which is currently up to 25%, with a small profits rate of 19%. However, profits exceeding £250,000 are taxed at a rate of 25% from April 1, 2023, as per Budget 2021.

Companies with profits up to £50,000 will continue to pay corporation tax of 19%. Exceptions apply to companies involved in oil extraction and oil rights.

Income Tax (Corporation Tax) In the UK

Companies in the United Kingdom have to pay corporation tax every year to the HMRC. The corporation tax rate is fixed at 19% at the base rate on the profits earned by the companies. On the other hand, if the profits of a company go beyond the threshold of £ 250 000, the corporation tax will be 25% as per the ruling of Budget 2021 and effective from 1st April 2023.

The small profit companies earning up to £ 50 000 will be liable to pay a corporation tax of 19%, effective also from 1st April 2023. Currently, the corporation tax rate is fixed at 19% of the profits except for the companies in the business of oil extraction and oil rights, also known as fence companies. Let’s move towards the next step of calculating the income tax provision using an example!

How to Calculate Provision for Income Tax in the UK

Calculating income tax provision generally involves the following:

• Applying the relevant UK tax rates to the total taxable income
• Considering allowances and reliefs
• Adjusting for previous overpayments or underpayments

For most companies, this also includes corporation tax calculations, while individuals focus on personal allowance and income tax bands.

Income Tax Provision Formula

The formula to calculate tax provision is:

Income tax provision = taxable income ✕ tax rate

UK companies use this formula as a starting point for how much tax they will owe in a year.

Note: The tax rate is not fixed. It may change depending on government policy and applicable thresholds.

Example

For example, Company A has the following information about the income and the expenses. First, the profit of this company will be calculated and then the income tax provision. So, let’s begin our discussion!

Particulars	Amount
Sales	£ 4 000 000
Cost of Goods Sold (COGS)	£ 1 800 000
Gross Profit	£ 2 200 000
Other Income Sources
Rental Income	£ 50 000
Total	£ 2 250 000
Expenses
Administrative Expenses	£ 400 000
Distributive Expenses	£ 200 000
Total Expenses	£ 600 000
Operating Profit	Total – Expenses = 2 250 000 – 600 000 = 1 650 000
Financial Expenses
Interest Expenses	150 000
Profit Before Taxes	1 500 000

The profit before tax is £ 1 500 000 which will be taxed in a particular year. Let’s say this tax provision is being calculated for 31st December 2022.

As the corporation tax is fixed at 19% for all corporations, so we will calculate the corporation tax provision at this tax rate.

After this, the income tax will be calculated at a particular tax rate.

Income Tax Provision = Profit Before Tax * Tax Applicable

= £ 150 000 * 19%

= £ 28 500

So, the company is expected to pay £ 28 500 in tax at the end of the financial year 2022. If the profit before tax differs, the tax liability will also vary at the end of that financial year. However, it helps estimate the total tax expenses at the start of the year.

Income Tax Provision Calculation Challenges

Calculating income tax provision can be a complex process due to the nuances of the UK tax regulations and the technical requirements of accounting standards like FRS 102. Some of the major calculation challenges are:

Deferred Tax Complexity

Changes in the UK corporation tax rates require you to recalculate your deferred tax balances based on enacted or substantively enacted rates. You can remeasure the deferred tax rates using the new rate that will be in effect when those taxes are actually paid.

Uncertain Tax Positions

You may face uncertainty about how tax rules apply in the UK or about potential disputes with HMRC. You must estimate the most probable outcome and reflect it in tax provisions.

Time Pressure and Reporting Deadlines

Income tax provisions are often prepared under tight deadlines during audits and year-end reporting. This time pressure can increase the risk of errors. It can also lead to greater reliance on estimates.

Data Quality and System Issues

Your financial data may not align with tax reporting requirements. This may need manual adjustments that can increase the risk of errors. Moreover, a lack of an integrated tax system can slow the process.

Group Structure and Consolidation

For group or multinational companies, each entity may be taxed at different rates. This makes calculations more complex. Since losses cannot always be shared in a group, it adds further difficulty.

Key Component of the UK Income Tax Provision

Some key components of the tax provision are:

Deferred Tax

Deferred tax accounts for temporary timing differences between accounting and taxable profits. This happens when your official accounts and HMRC rules for when tax is due differ from standard accounting rules.

Current Tax Liability

Current tax liability is the amount of Corporation Tax you expect to pay on your taxable profits. Currently, the main rate of Corporation Tax is 25% for profits of more than £250,000.

However, for small companies with profits under £50,000, the Corporation Tax rate is 19%.

Adjustment for Prior Periods

Sometimes, the actual tax bill you paid to HMRC differs from the estimate made in the previous year’s accounts. In such a case, you must add or subtract the difference to reconcile these differences.

Why is Income Tax Provision Important?

When you plan your tax provision early, it can really help your company remain compliant. Some of the benefits of income tax provision are:

Accuracy for Investors

Investors need to see the net profit after tax. By matching tax liabilities with the income that generated them, shareholders can get a clear view of the company’s financial health.

Cash Flow Management

Tax provision helps businesses set aside necessary funds to cover their tax bills when they fall due. By calculating the provision, you know exactly how much cash you may need to meet the corporation tax deadlines.

HMRC Compliance

You must record an accurate provision to comply with the UK Generally Accepted Accounting Practice (GAAP). It can also help you avoid penalties for misreporting.
