Is a farming business partnership exempt from this section 163 limitation if it qualifies as a small business ($25,000,000 in sales, etc)? Or does it have to file an election to be excepted from this limitation? I thought that if it met the small business definition, nothing further had to be done. But my software update for today is indicating that an election has to be attached if it is farming business, regardless of small business guidelines.If not, a Form 8990 has to be completed. Help please!
