Tax season is here; also, did you know that today is the 100th anniversary of the income tax? The 16th Amendment to the U.S. Constitution, authorizing a graduated income tax, was ratified on February 25, 1913 (you can read it here). Today, our state and nation’s income tax laws are varied and complex, but the Colorado Dept. of Revenue has simplified the laws for you in their FYI publications series. Each FYI fact sheet covers in plain language one area of income tax policy that consumers may have questions about, such as tax credits; tax forms; part-year residents and non-residents; interest; military servicepersons; pensions; filing jointly and/or with dependents; and much more. So if you have questions while preparing your taxes this year, the FYI publications – and our library – can help.
