Paying taxes is an obligation we all have as citizens because taxes

The obligation to pay taxes is imposed on members of society by law. Without a legal obligation, there is no moral obligation to pay taxes. The moral duty to pay taxes is directly derived from the law and, therefore, the moral standard and the legal standard must be the same.

Explanation:

1. Contention: The filing of a tax return is voluntary.

Some taxpayers assert that they are not required to file federal tax returns because the filing of a tax return is voluntary. Proponents of this contention point to the fact that the IRS tells taxpayers in the Form 1040 instruction book that the tax system is voluntary. Additionally, these taxpayers frequently quote Flora v. United States, 362 U.S. 145, 176 (1960), for the proposition that "[o]ur system of taxation is based upon voluntary assessment and payment, not upon distraint."

The Law: The word “voluntary,” as used in Flora and in IRS publications, refers to our system of allowing taxpayers initially to determine the correct amount of tax and complete the appropriate returns, rather than have the government determine tax for them from the outset. The requirement to file an income tax return is not voluntary and is clearly set forth in sections 6011(a), 6012(a), et seq., and 6072(a) of the Internal Revenue Code. See also Treas. Reg. § 1.6011-1(a).
