Deductions & credits

Thanks for the reply about tools purchased for home improvement projects.  

 

But I also still am unsure how much detail the IRS might want for documentation of improvements.   Some projects where I paid a contractor and had a contract are will documented.  But other smaller projects - some of which go back 30 years, are things that I don't have every cancelled check or credit card receipt, and it is impossible to resurrect those records from so long ago.  I a running tally of expensed, with dates and vendors sufficient?
