Profit and Loss Line Item Labels Explained

The profit and loss (income statement) section of the TinyTax filing form uses labels defined by the FRC (Financial Reporting Council) iXBRL taxonomy. These labels apply to all UK limited companies — not just manufacturers or product businesses.

Why the Labels Look Manufacturing-Specific

The label "Cost of raw materials and consumables" is the FRC taxonomy's standard name for the XBRL element `core:RawMaterialsConsumablesUsed`. HMRC and Companies House validate the underlying XBRL identifier, not the human-readable label — so it does not matter that your company is a service business, consultancy, software company, or retailer. Using this field is correct and accepted.

What to Enter in Each Field

Field	XBRL element	What to enter
Cost of raw materials and consumables	`core:RawMaterialsConsumablesUsed`	All direct costs: stock, materials, subcontractors, cost of services delivered, goods purchased for resale, direct overheads
Staff costs	`core:StaffCostsEmployeeBenefitsExpense`	Employee wages, salaries, employers' NI, pension contributions
Depreciation and other amounts written off assets	`core:DepreciationAmortisationImpairmentExpense`	Annual depreciation charge on fixed assets
Other charges	`core:OtherOperatingExpensesFormat2`	Remaining operating expenses: rent, utilities, professional fees, software subscriptions, insurance, marketing, etc.

Common Approaches for Service Companies

Consultancy / professional services firm: direct costs (subcontractors, direct travel, project costs) go in "Cost of raw materials and consumables"; all other overheads go in "Other charges".

Software / technology business: hosting costs, third-party API costs, and any direct costs go in "Cost of raw materials and consumables"; office costs, subscriptions, and general overheads go in "Other charges".

Retailer or distributor: cost of goods purchased for resale goes in "Cost of raw materials and consumables".

If all your costs are overheads with no direct costs, you can leave "Cost of raw materials and consumables" at zero and enter everything in "Staff costs" and "Other charges" as appropriate.

Where These Fields Appear in the Income Statement

The income statement in your filed accounts follows the standard UK iXBRL format. The order is:

Income statement line	Position
Turnover	Top
Cost of raw materials and consumables	Above gross profit
Gross profit	Calculated subtotal
Staff costs	Below gross profit
Depreciation	Below gross profit
Other charges	Below gross profit
Profit before Taxation	Calculated result after all operating costs
Corporation tax charge	Below Profit before Taxation
Profit for the year	Bottom

Other charges appear above Profit before Taxation — because all operating expenses are inputs used to calculate the profit figure. Profit before Taxation is the result of deducting them from gross profit, not a starting point.

This means the full calculation is:

> Turnover − Cost of sales = Gross profit > Gross profit − Staff costs − Depreciation − Other charges = Profit before Taxation > Profit before Taxation − Corporation tax = Profit for the year

The only item that appears below Profit before Taxation is the Corporation tax charge (and any deferred tax movement), because tax is applied to the profit rather than deducted to calculate it.

If your accounts from a previous tool showed expenses below Profit before Taxation, that tool was using a non-standard layout. The format TinyTax generates matches the FRC taxonomy and Companies House's iXBRL requirements.

Common Questions

Does HMRC reject accounts that use these fields for non-manufacturing costs?

No. HMRC and Companies House accept the XBRL tags regardless of the business type. The label text in your submitted accounts will show "Cost of raw materials and consumables" — this is the legally prescribed label and will not cause a rejection or query from HMRC.

Can I split my costs across multiple fields?

Yes, and this often makes the accounts clearer. A common approach for service companies is to put direct project costs in "Cost of raw materials and consumables", employment costs in "Staff costs", and remaining overheads in "Other charges".

Why do my expenses appear above Profit before Taxation?

This is correct. All operating expenses — staff costs, depreciation, and other charges — are deducted from gross profit to arrive at Profit before Taxation. They appear above PBT because they are inputs to the calculation. The only item that appears below PBT is the Corporation Tax charge.
