Managing Unpredictable Farm Earnings

Agricultural income rarely follows a steady pattern. Many farmers see profits rise and fall significantly from one year to the next, often due to factors beyond their control.
Weather conditions, disease outbreaks, fluctuating market prices for products such as milk, volatile costs for essentials like feed, fuel, and fertiliser, and changes in government policy all contribute to this uncertainty.
Because of this instability, farmers’ averaging is a tax relief mechanism designed to smooth profits over time. When applied effectively, it can reduce tax liabilities and improve cashflow stability.
Eligibility and Scope
This relief is available to individuals operating as sole traders or in partnerships. It does not apply to limited companies, as corporate tax rates tend to be more consistent, whereas personal tax rates can vary significantly depending on income levels.
Averaging applies to farming profits after capital allowances have been deducted.
Participation is optional but, where used, farmers can choose to:
Spread profits over two years
Spread profits over five years
To qualify, there must be at least a 25% difference in profit between the years being compared.
Factors That Influence the Decision
Whether to use averaging depends on several factors, including:
The level of profit in the current year compared to previous years
Tax rates applied in earlier periods
The impact on future tax payments (payments on account)
Expected business performance
National Insurance contributions
When Income Drops
In sectors such as dairy, periods of strong returns have recently been followed by falling prices. Even where averaging has already been used, some farmers may previously have faced high tax rates, particularly where income exceeded £100,000. At this level, the personal allowance is reduced, resulting in effective tax rates of up to 62%.
Where profits have since declined, there may be an opportunity to reallocate income from earlier high-tax years into a lower-tax year. For example, moving income into a year where unused basic rate band remains could significantly reduce the tax payable. When combined with National Insurance savings, the overall effective rate can fall considerably.
However, averaging higher income into a later year may increase Income Tax payments on account for the following year. While these can be reduced if appropriate, setting them too low may result in HMRC interest charges, currently at 7.75%.
When Income Rises
While falling profits can create opportunities, rising profits present a different set of planning considerations. In years where profits increase sharply, such as when milk prices are high or there has been limited expenditure on plant and machinery, averaging can also be beneficial.
Income can be shifted back into earlier years where there may be unused personal allowances or lower-rate tax bands, reducing the amount subject to higher tax rates.
In these circumstances, averaging can also reduce payments on account for the following year automatically, easing cashflow pressures. Unlike a simple request to reduce payments on account, this approach will not lead to interest charges if profits continue to grow.
What This Means for You
Farmers’ averaging is not a one-size-fits-all solution, as its effectiveness depends on individual circumstances. Determining the best approach can be complex and may involve revisiting previous tax returns.
While the calculations can be intricate, the potential tax savings can be significant. If you would like to explore whether averaging could benefit your business, please speak to our director, Heather, who will be happy to help.
