Dictionary / Carryback
What does Carryback mean in accounting?
Quick definition
Tax & complianceThe amount, for federal income tax purposes, of the net (operating) loss for a given year of an individual, corporation, or other taxpayer carrying on a business, subject to certain adjustments, that may be deducted from the net income of three preceding years. This term guides how bookkeepers record, classify, and explain related transactions in routine financial reporting.

Examples
A loss year applied to three prior years
You run a tile shop. You close December 2024 with a $36,200 net operating loss after a commercial job stalled and you still paid a porcelain supplier for unused porcelain. Your 2021, 2022, and 2023 federal returns each showed net income, so that $36,200 is the carryback: after the allowed tax adjustments, you may deduct it from those three preceding years. You and your preparer work it on the federal return, not by adding a Carryback account in QuickBooks Online. The 2024 P&L still shows the loss year as it happened.
Leftover after prior years is carryover
You run a cleaning company. After a dental-office client drops your contract in June 2022, the year ends with a $47,500 net operating loss. The three preceding years only had $16,800 of combined net income. After you apply $16,800 as carryback against those prior years, $30,700 is still unused. That leftover is carryover, not more carryback; you cannot keep deducting it from years before the three-year window. Keep the leftover on the tax workpapers for succeeding years, and do not book it as a 2022 asset in Xero.
Why it matters
Carryback is a federal income tax figure: a net operating loss from a loss year that, after the allowed adjustments, you may deduct from net income of the three preceding years. You will not post this most months; it shows up after a loss year, when you or your preparer files the federal return. Mix it with carryover and you send unused loss to future years before you use those three prior years, or you keep applying leftover outside that window. The books still show the loss year as it happened, so do not add a carryback line to the general ledger just because the tax return uses the word.
