Hi, if it the amortizable goodwill, my client would have $20k amortization deduction each year for 15 years, which keeps making the company has loss carryover over each year. In this case, do i need recapture all the amortization when he sells the business at the end of 15 year and realize $300k long-term gain if he get paid this amount from his buyer as well?

Or should i just keep the intangible asset there, not amortize at all. By the time he sells the shop, just realize the gain in amount of difference of intangible asset he purchased and sold.
