A financial obligation is any legally enforceable duty to pay money to another party, and in everyday life it takes four forms: debts you voluntarily take on, taxes imposed by law, payments a court orders you to make, and the recurring household bills tied to services you use. Each type is enforceable in its own way, and each carries real consequences — damaged credit, garnished wages, liens on your property — when you fall behind.
Debts You Agreed To
Contractual debts start with your signature. When you sign a promissory note, a credit card agreement, or a loan contract, you consent to specific terms: the amount, the interest rate, and the repayment schedule. That consent is what makes the obligation enforceable in court.
A mortgage is the standard example. Financing a home means signing a security instrument (called a mortgage or a deed of trust, depending on the state) that lets the lender foreclose if you stop paying, plus a promissory note that is the actual promise to repay. Auto loans follow the same pattern, with the lender holding a lien on the vehicle until the balance is cleared. Credit cards create a revolving obligation instead: the balance moves up or down each month based on what you charge and what you pay.
Co-signing carries the same weight as borrowing directly. Federal regulations require the lender to give you a separate notice before you co-sign, warning that the creditor can collect the full debt from you without first pursuing the primary borrower, and can use the same tools — lawsuits and wage garnishment included — against you.1eCFR. 16 CFR 444.3 – Unfair or Deceptive Cosigner Practices
Taxes Imposed by Law
Tax obligations do not require your signature. They arise automatically when you earn income, receive investment profits, or own property.
Income and Payroll Taxes
Federal income tax comes from Title 26 of the United States Code, which taxes individuals on their taxable income under a graduated rate structure.2Office of the Law Revision Counsel. 26 USC Subtitle A, Chapter 1, Subchapter A – Determination of Tax Liability Payroll taxes fund Social Security and Medicare on top of that. The Social Security tax is 6.2% for employees and 6.2% for employers; Medicare is 1.45% each. Employees earning more than $200,000 in a calendar year owe an additional 0.9% Medicare tax on the amount above that threshold.3Internal Revenue Service. Topic No. 751 – Social Security and Medicare Withholding Rates
Social Security tax applies only up to an annual cap, which is $184,500 for 2026.4Social Security Administration. Contribution and Benefit Base Wages above that are exempt from the 6.2% Social Security tax, but Medicare tax applies to all earnings with no limit.3Internal Revenue Service. Topic No. 751 – Social Security and Medicare Withholding Rates
Property Taxes
Property taxes are a local obligation created by owning real estate, and in some places by owning vehicles or business equipment. Local governments assess the property’s value and charge a percentage to fund schools, roads, and public services. You never sign an agreement for property tax. The obligation exists by operation of law, and it continues for as long as you hold the asset.
Payments a Court Ordered You to Make
Court-ordered obligations arise from legal proceedings rather than agreements, and you owe the money whether or not you consent to the arrangement.
Child support is the most common. Under the federal Child Support Enforcement Act, every state runs a program to locate noncustodial parents, establish paternity, and collect payments.5Office of the Law Revision Counsel. 42 USC Chapter 7, Subchapter IV, Part D – Child Support and Establishment of Paternity A judge sets the amount using income guidelines, and the obligation runs until the court changes it or the child reaches the age specified in the order. Alimony works the same way, with a court ordering payments from one former spouse to the other based on factors like the length of the marriage, each party’s income, and financial need.
Courts also impose money obligations through restitution and civil judgments. In a criminal case, a judge can order a defendant to repay a victim for losses caused by the crime.6Office of the Law Revision Counsel. 18 USC 3663 – Order of Restitution In a civil lawsuit, a court can award damages when it finds one party harmed another. Both are backed by the court’s power to garnish wages or seize assets.
If your financial circumstances change significantly after an order is entered, you can petition to modify the amount. Courts generally require a substantial change — a major swing in income, a job loss, or a serious medical condition — that was not anticipated when the original order was issued. Until a judge formally changes the order, you remain liable for the original amount.
Recurring Household Bills
Everyday household costs are technically contractual, but they behave differently from large one-time loans because they recur and are tied to necessities. Signing up for electricity, water, or natural gas service means agreeing to pay for whatever you use during each billing cycle. You can cancel, but you still owe for any usage that has already occurred.
Insurance premiums for health, auto, and homeowners coverage are another recurring obligation. You pay to keep the policy in force, and if you stop paying, coverage lapses and leaves you exposed. A lease or rental agreement locks in a fixed monthly payment for the right to live in a property; unlike a mortgage, it builds no equity, and breaking the lease early usually triggers penalties or an ongoing rent obligation until the landlord finds a replacement tenant.
What Happens If You Don’t Pay
Ignoring a financial obligation does not make it go away. Creditors, courts, and government agencies have several enforcement tools, and consequences compound the longer you wait.
Wage Garnishment
For ordinary consumer debts like credit cards and medical bills, federal law caps garnishment at the lesser of 25% of your disposable earnings or the amount by which your weekly pay exceeds 30 times the federal minimum wage.7Office of the Law Revision Counsel. 15 U.S. Code 1673 – Restriction on Garnishment Child support allows much steeper garnishment: up to 50% of disposable earnings if you are supporting another spouse or child, or 60% if you are not, with an extra 5% if payments are more than 12 weeks overdue.8U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act Federal and state tax debts are exempt from the 25% cap entirely, so the IRS and state tax agencies can take a larger share.
Liens and Asset Seizure
When a creditor wins a court judgment, the debt can attach to your property as a lien, meaning it must be paid before you sell the asset free and clear. A federal judgment lien lasts 20 years and can be renewed for another 20.9Office of the Law Revision Counsel. 28 U.S. Code 3201 – Judgment Liens The IRS can also file a federal tax lien for back taxes, though a mortgage or other security interest recorded before the IRS files its notice of lien generally takes priority.10Internal Revenue Service. Federal Tax Liens Many states offer a homestead exemption that shields some home equity from most creditors, but that protection generally does not apply to mortgage lenders, tax liens, or child support enforcement.
Credit Report Damage
Missed payments, defaults, and collection accounts land on your credit report and make future borrowing, renting, and even some hiring decisions harder. Federal law caps how long most negative items can stay. Collection accounts, civil judgments, and paid tax liens drop off after seven years. A Chapter 7 bankruptcy stays for up to 10 years from the filing date.11Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports
IRS Penalties and Payment Plans
Filing your federal tax return late triggers a penalty of 5% of the unpaid tax per month, up to 25%. If the return is more than 60 days late, the minimum penalty is the lesser of $525 (for returns due in 2026) or 100% of the tax owed.12Internal Revenue Service. Topic No. 653 – IRS Notices and Bills, Penalties and Interest Charges A separate failure-to-pay penalty of 0.5% per month applies to any balance left unpaid after the filing deadline, also capped at 25%. When both apply in the same month, the filing penalty is reduced by the payment penalty, so the combined charge is 5% per month.13Internal Revenue Service. Failure to Pay Penalty
If you cannot pay the full bill, the IRS offers short-term payment plans of up to 180 days with no setup fee, and long-term installment agreements with setup fees ranging from $22 to $178 depending on how you apply and how you pay.14Internal Revenue Service. Payment Plans – Installment Agreements An approved installment agreement cuts the failure-to-pay penalty from 0.5% to 0.25% per month.13Internal Revenue Service. Failure to Pay Penalty
Limits on Collectors and Old Debts
Once an unpaid obligation is handed to a third-party collection agency, federal law restricts what that collector can do. The Fair Debt Collection Practices Act prohibits threats of violence, harassing calls, misrepresenting the amount owed or the collector’s identity, and contacting third parties like your employer or family about the debt (narrow location-only exceptions apply). If you have an attorney, the collector has to communicate with the attorney instead of you.15Federal Trade Commission. Fair Debt Collection Practices Act Text
Every state also sets a statute of limitations on collection lawsuits, generally between three and fifteen years for written contracts. After that window closes, a creditor can no longer sue you. Making a partial payment or acknowledging the debt in writing can restart the clock in many states, so it pays to know where the deadline stands before you respond to an old debt.
What Bankruptcy Will Not Erase
Bankruptcy can wipe out many financial obligations, but several categories are specifically excluded. Chapter 7 (liquidation) and Chapter 13 (repayment plan) will not discharge:
- Domestic support obligations: child support and alimony survive bankruptcy in all cases.16Office of the Law Revision Counsel. 11 U.S. Code 523 – Exceptions to Discharge
- Most tax debts, including recent income taxes, taxes on unfiled returns, and any tax involving fraud.
- Federal and qualified private student loans, unless you can prove repayment would impose an undue hardship — a standard courts read strictly.
- Debts arising from fraud, false representations, or embezzlement.
- Debts for death or personal injury caused by driving under the influence of alcohol or drugs.
- Criminal fines, penalties payable to a government agency, and restitution orders.
Anything outside these categories may be dischargeable, but the exclusions above stay with you regardless of which chapter you file.
