Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within a cell. solvent (from the Latin solvÅ, I loosen, untie, I solve) is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution.
An example of supporting documentation is: â UNINSURED MEDICAL EXPENSES . Evidence (itemized bills) to show what treatment was provided, when it was provided, and the charge, as well as evidence of insurance filing and payments (insurance company summary sheets or claims reports, etc.) indicating what was paid by your insurance must be included.
In most cases, you should plan on keeping tax returns along with any supporting documents for a period of at least three years following the date you filed or the due date of your tax return, whichever is later. So for example, if you filed your 2015 tax return on February 1, 2016, you should have kept the return and supporting documents until at least April 15, 2017. What tax records should I keep? You should keep every tax return and supporting forms. This includes W-2s, 1099s, expense tracking, mileage logs if you itemize and other documents.
