4. Start worksheets and lists for 2019 and 2020

If you plan to itemize your tax deductions, a good rule of thumb is to start a checklist of questions to gather pertinent information.

For example, you may need to get tax information from your child care provider, or you may need to figure out the number of square feet in your home office.

You should also keep a record showing how you estimated amounts or allocated them between different categories.

Aside from being necessary if the Internal Revenue Service (IRS) ever questions your return, that information may be useful in future tax years.
