You owe taxes because you didn't pay enough throughout the year, usually due to under-withholding from paychecks, especially after life changes (marriage, new dependents, multiple jobs), freelance/gig income where taxes aren't withheld, or changes in your deductions/credits, making your final bill higher than what was paid in. The U.S. tax system is "pay-as-you-go," meaning you must cover your tax liability via withholding or estimated payments; owing means you underpaid during the year.

One of the main culprits behind owing taxes is insufficient tax withholding. This happens when your employer doesn't take enough taxes out of your paycheque throughout the year. It's more likely to happen if you have multiple jobs, switch jobs, or your income changes unexpectedly.
If you claimed 0 and still owe taxes, chances are you added “married” to your W4 form. When you claim 0 in allowances, it seems as if you are the only one who earns and that your spouse does not. Then, when both of you earn, and the amount reaches the 25% tax bracket, the amount of tax sent is not enough.
Congress used the power granted by the Constitution and Sixteenth Amendment, and made laws requiring all individuals to pay tax.

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.

If you mistakenly filed as Single but qualify for Head of Household (HOH), you likely paid more tax due to a smaller standard deduction and higher tax brackets, so you should amend your return using Form 1040-X after the IRS accepts your original return; this correction, done by mailing the form, gives you a larger standard deduction and potentially a bigger refund, though processing takes time (up to 16 weeks).
(Federal withholding, state withholding, Medicare, and some local taxes are paid on all taxable wages.) Miscalculating these amounts can lead to overpaying or underpaying taxes, which can create compliance and cash flow issues. Common errors include: Overpaying by applying taxes above the wage base limit.
You suddenly owe taxes because your payments during the year (withholding or estimated) didn't cover your actual tax liability, often due to life changes like a raise, new job, side hustle, or selling investments, which increased your income or reduced deductions, or because tax laws/credits changed, leaving you with a surprise bill. Common culprits are under-withholding from your paycheck, earning taxable gig income, or missing quarterly payments.
If you want to avoid a tax bill, check your withholding often and adjust it when your situation changes. Changes in your life, such as marriage, divorce, working a second job, running a side business, or receiving any other income without withholding can affect the amount of tax you owe.
