interest tracing rules- borrowed mortage funds form primary house to pay off rental property debt

I  like to know if mortage interest is deducted ( on schedule E)  if  client refinances a  primary residence to pay off a rental property mortage $400,000- original purchase price?

Does the tracing rule apply? do you need to make an official 10-T  election   

I heard the The 10-T election should be physically attached to the taxpayer's return and applies to the interest paid on that debt for the current and future years.  How do you make election using proseries.

 

Thanks,

John

IMO, the refi interest allocated to the rental property can be deducted on sch e and that tracing rules apply. Be sure to document. I don’t think 10-t is required but will let others weigh in.

If at first you don’t succeed…..find a workaround

If it's in there, and if it's needed, there is a separate set of forms under "Federal Election" in the All Forms menu.

If I remember correctly ... is it a separate loan that was only for the rental payoff?  Or does the loan combine their personal residence acquisition/improvement debt along with the new $400,000?  Is their qualified personal Residence loan amount over $750,000?

You make the -10T election by allocating the interest to where the funds were used. No formal election needed.

The more I know the more I don’t know.

The IRS interest tracing rules are found primarily in Treasury Regulation 1.163-8T  and detailed in IRS publications like  Publication 550, Investment Income and Expenses and Publication 936, Home Mortgage Interest Deduction. 

P.S. I should share that credit really belongs to Google Chrome AI, but that would expose trade secrets. 

Answers are easy. Questions are hard!

if you attach a election statement to tax return, how do you know if the IRS approved the election?
