One approach that we take at TWRU to ensure that a client's tax deductions are always compliant with current tax laws is what we call the 2-year rule. For example, if you were walking onto a plane and need to get documentation to an IRS agent, wouldn't it be nice to have that information readily available? Instead of disrupting your life to scramble for documents, we recommend clients keep 2 years' worth of source documents that support the deductions taken in a place that is easily accessible. This method helps clients to feel less vulnerable and more comfortable in making decisions throughout the year.
If you're using a search engine to find current information about tax laws, you can set up the filters to show you articles from the IRS website that were posted in the last year. Other websites may have made posts recently that were based on outdated information so it's better to look up current laws on the IRS' website.
