<bot>: The most up to date tax laws in the US are those outlined in the Internal Revenue Code (IRC), which are set by the Internal Revenue Service (IRS). This body regulates tax in the US and is responsible for enforcing the current legislation that determines how individuals and businesses pay tax. The IRS also provides detailed guidance on what is deductible and what isn’t, and how to file taxes properly. The current tax laws are typically updated every year, though 2020 and 2021 saw special changes due to the COVID-19 pandemic.
