Then we have the accrued $300,000 in warranty liability at year-end and could not deduct it on the tax return for this year but warranty will be paid out in the following year. The accrued warranty liability will be record on the year end financial statements, but with the timing difference the warranty liability will show on the following tax return. “The warranty calculations can require consideration of beginning balances, additional accruals, and warranty work performed. Assume Zeff Company had a beginning-of-year Warranty Liability account balance of $25,000. During the year Zeff sells $3,500,000 worth of goods, eventually expecting to incur warranty costs equal to 2% of sales ($3,500,000 X 2% = $70,000). The 2% rate is an estimate based on the best information available. Such rates vary considerably by company and product. $80,000 was actually spent on warranty work. How much is the end-of-year Warranty Liability? The T-account reveals an ending warranty liability of $15,000.”
