Examples
Books take less depreciation than the return
You run a machine shop on accrual basis. For 2025 the books take $8,400 of depreciation on a CNC mill; the federal return uses a faster recovery method and takes $19,200 on the same mill. Book profit is $10,800 higher because the books recognized less expense. On January 18 your CPA sends a year-end workpaper with an estimated future tax on that excess. Debit income-tax expense and credit deferred income tax, a liability, for the amount on that workpaper, and look for the credit on the December 31 balance sheet, not as this year's IRS payment.
A prepaid contract is not a tax estimate
You run an HVAC shop. On November 4, an apartment complex pays $6,000 for a 2026 rooftop maintenance plan. Checking increases $6,000; credit deferred income (or customer deposits), not deferred income tax. That cash is unearned work, not estimated tax on extra book profit. In QuickBooks Online or Xero, use a customer-deposit liability, then move the $6,000 to service income as you complete the visits next year.
Why it matters
Deferred income tax is the estimated tax you will owe later because the books recognized more profit than the tax return. You will not post it most months, and many cash-basis small businesses never post it at all, because their books and the return use the same cash timing. It shows up at year-end when you close on accrual basis and the return uses a different rule, such as a faster equipment write-off. Mix it with deferred income and you treat unearned customer cash as a tax bill; mix it with this year's tax payable and you hide tax you already owe, while a deferred liability is the broader label for any debt pushed past its usual date.
