Americans file tax returns primarily to fulfill legal obligations to the federal, state, and local governments, as required by the Internal Revenue Code. It is a mandatory process for most, serving to report income, reconcile taxes withheld from paychecks, claim refunds, or pay taxes owed.
The reason we have to file taxes is to rectify what the government took out of our paychecks versus what we actually owe based on the tax code. Over the years, the U.S. government realized it is easier to collect more taxes and send you back money versus the other way around.
Generally, most U.S. citizens and permanent residents who work in the United States need to file a tax return if they make more than a certain amount for the year. Taxpayers may have to pay a penalty if they're required to file a return but fail to do so.
There are two reasons people get tax refunds: They overpaid their taxes throughout the year. They qualify for refundable credits that exceed their tax liability. One is pretty straightforward. You pay that. At the end of the year, you re-assess.
Benefits of Filing Taxes
The tax preparation process provides the tangible returns of establishing good financial habits, developing techniques to navigate financial systems, reducing stress and life disruptions caused by financial problems, and empowering people to work towards achieving financial goals.
If penalties and interest aren't motivating enough and you outright refuse to file taxes, the IRS can enforce tax liens against your property or even pursue civil or criminal litigation against you until you pay.
There isn't one single "highest tax paying country" as it depends on what's measured (income, corporate, total tax revenue), but countries like Denmark, Finland, Japan, and Ivory Coast (Côte d'Ivoire) consistently rank highest for top personal income tax rates, often exceeding 50-60%, while nations like Belgium can have the highest overall tax burden on labor (tax wedge) for average earners, with high social security. Nordic countries and some European nations generally have high income taxes, funding extensive social services.
Why are taxes so complicated? Our tax system could be simple if its only purpose were to raise revenue. But it has other goals, including fairness, efficiency, and enforceability. And Congress has used the tax system to influence social policy as well as to deliver benefits for specific groups and industries.
Who Does Not Have to Pay Taxes? You generally don't have to pay taxes if your income is less than the standard deduction or the total of your itemized deductions, if you have a certain number of dependents, if you work abroad and are below the required thresholds, or if you're a qualifying non-profit organization.
The federal government funds a variety of programs and services that support the American public. The government also spends money on interest it has incurred on outstanding federal debt, including Treasury notes and bonds. In 2025 the federal government spent $7.01 trillion, with the majority spent on Social Security.
And it is important to notethat without the income tax, prices for almost all products willgo down before the sales tax is applied. With savings and investments no longer taxed, Americans willenjoy a capital formation boom.
Unemployment compensation generally is taxable. Inheritances, gifts, cash rebates, alimony payments (for divorce decrees finalized after 2018), child support payments, most healthcare benefits, welfare payments, and money that is reimbursed from qualifying adoptions are deemed nontaxable by the IRS.
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
Failing to file taxes is a violation of the law, and the Internal Revenue Service (IRS) takes non-compliance seriously. While missing a filing deadline may initially result in penalties and interest, repeated or willful failure to file can lead to criminal charges.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
But how people define “upper class” differs. Some say you'd need to be making twice the median income, or around $167,460. Even more elite are those who find themselves in the top 5 percent of earners. In the U.S., you'd need to be making about $336,000 to find yourself in the top 5 percent, according to Census data.
