This discussion provides some great insight into my question, but isn't quite on point.

I have a medical practice with significant inventory (~$100K) and significant revenue from the sales of those items (~50% of total revenue). Overall gross receipts is less than $3M.
I understand, from a CPE I attended, that the rules around cash basis and 'ignoring' inventory are much more liberal in 2018. Based on the fact above, can I make an accounting method change for 2017 and write off inventory to zero (incidental materials and supplies)? I found an article from 2010 discussing RP 2009-39 stating an automatic change to incidental materials and supplies is not available. Does anyone know if anything has changed on this?
