Carryback and carryforward are tax provisions that allow taxpayers to apply a net operating loss or other tax loss to different tax years to reduce taxable income or tax liability. A carryback uses current losses to offset income reported in prior years, potentially producing a tax refund. A carryforward uses losses to offset future income, lowering taxes in future periods when profits arise.

Rules governing carrybacks and carryforwards vary by jurisdiction and tax regime. Some systems permit both options, with specific time limits, caps on the amount that can be offset, or eligibility requirements. Others restrict one or both options, or set expiration dates for unused losses. In many places, the ability to use losses may be limited by ownership changes, minimum profit thresholds, or interaction with other tax provisions.

Practical considerations include the origin of losses (operating losses versus eligible tax credits), the expected timing of future profits, and liquidity needs. Carrybacks can provide immediate refunds of previously paid taxes, while carryforwards offer a way to smooth tax burdens across years with rising profits. Taxpayers must maintain documentation and adhere to jurisdiction-specific rules to ensure proper application and to avoid penalties.

An illustrative scenario: a company incurs a loss in year one and generates positive income in year two. If the jurisdiction allows a carryforward, the year two tax liability can be reduced by applying the year one loss to future profits. If a carryback is permitted, the current loss could be applied to prior year income, potentially yielding a refund of taxes already paid.

Carryback and carryforward are common features of corporate and individual tax planning, reflecting attempts to align tax liabilities with fluctuating earnings.
