Loss carryback

“A tax rule that may let a business apply a current-period tax loss against taxable profits from an earlier period, potentially creating a refund.”

Why loss carryback matters to a first-time founder

If available, carrying a loss back can return tax paid in a profitable earlier period and improve cash when trading is weak. Eligibility, the carryback window, caps and claim process depend on the tax jurisdiction and can change between accounting periods.

Examples of loss carryback

A company paid corporation tax on $100,000 of taxable profit last year, then records an eligible $40,000 tax loss this year. If local rules permit a one-year carryback, it may offset that loss against last year’s profit and claim back the related tax.

Common misunderstanding

It is not an automatic refund of the cash lost by the business. The relief only affects qualifying taxable profit and usually requires a claim. It also differs from a loss carryforward, which uses the loss against future rather than earlier profits.

When to use it

Ask a qualified tax adviser about it when the business moves from profit into loss or closes an activity. Confirm the applicable dates, loss type, ownership conditions and filing deadline in your jurisdiction. Do not recognise a refund until entitlement is supportable.
