I do not know how to share a file on here

It is nothing fancy though - I just a file saved as 'Expenses 20xx' with a worksheet for each of those headings created within it and that I have column on each sheet for the date, description of expense, amount of expense and any KM driven associated with the receipt and than it auto sums the total of the expense and the KM columns for me at the bottom of the page. At the end of the year you can print them out for taxes or you can create another 'sheet' where you just put the 'tallies' of each expense heading and print that out. I also have a 'final tally' spreadsheet that I add up all my 'business KM' with for the vehicle equation in the car.
