In 2018 improvements were made to the interior of a building (QIP) which under the then TCJA was 39 Yr property, the 2018 tax return has already been filed. I have not filed the 2019 return yet. Under the CARES Act I want to 1.) switch to 15 Yr property, and 2.) Claim bonus depreciation for the previous expenditure.
Is DCN 244 the correct Automatic Change Request DCN number for both switch to 15 Yr and claiming bonus? Is there anything tricky in completing this Form for QIP in Lacerte?
Yes, DCN covers it all.
Sorry, I can't help you with how to do it in Lacerte (I use ProSeries).
Have you compared the results with adding it to 2019, versus amending 2018? You may want to do that.
As far as Form 3115 goes, it might be easier to amend 2018 than to file Form 3115 with 2019. But comparing the tax due in both scenarios would be a good idea.
