How to Fill Out Income and Expense Declaration for Child Support

To fill out an income and expense declaration for child support, you download your state’s current version of the form, report every source of gross income with pay stubs and tax returns to back it up, list your payroll deductions and monthly living expenses using real numbers, redact sensitive identifiers, then sign it under penalty of perjury and serve a copy on the other parent. The form is the primary financial record the judge will rely on, and the numbers you put on it are the raw inputs for your support calculation.

Get the Right Form for Your State

There is no single national form. Each state has its own financial disclosure document, and the name varies: “Income and Expense Declaration,” “Financial Affidavit,” “Case Information Statement,” or something similar depending on where you live. Your local family court’s website will have the correct form, usually as a downloadable PDF. Some states also offer guided electronic filing that walks you through each section online.

Using the wrong form or an outdated version is a common reason filings get rejected. Confirm you have the current version directly from your court’s website or the clerk’s office before you start. If you’re unsure which form applies, call the family court clerk. They can’t give legal advice, but they can tell you which form number to use.

Gather Your Financial Documents First

Pulling together your paperwork before you sit down with the form saves a lot of backtracking. You’ll want:

  • Pay stubs from at least the last two months
  • Your most recent federal and state tax returns
  • W-2 or 1099 forms from the prior year
  • Your most recent Schedule C if you’re self-employed (the IRS form where sole proprietors report business income and expenses)
  • Mortgage statement or lease agreement
  • Utility bills
  • Car loan and insurance statements
  • Childcare receipts and any out-of-pocket medical bills for the children

Courts want actual numbers backed by actual paperwork, not ballpark guesses. If the other parent challenges your figures at a hearing, the judge will ask what documentation you have. “I estimated” is not an answer that builds credibility.

Report Every Source of Income

The income section is the part courts scrutinize most closely. You must report gross income from every source, not just your primary job. That includes wages, salary, overtime, and commissions, plus rental income, dividends and interest, retirement distributions, Social Security benefits, disability payments, unemployment benefits, and any side or freelance earnings.

If your income is steady, use your year-to-date pay stub figures to calculate an average monthly gross. If it fluctuates because of seasonal work, commissions, or bonuses, add up everything you earned from that source over the past 12 months and divide by 12. Courts understand that some months are better than others, but they want a realistic average, not a cherry-picked low month.

If You’re Self-Employed

Self-employment income requires extra documentation because there’s no employer-issued pay stub to verify your numbers. Attach a profit and loss statement or your Schedule C from your most recent federal tax return, which reports gross business receipts minus allowable business expenses to arrive at net profit.1Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Some courts ask for two years of profit and loss statements to smooth out year-over-year swings.

Courts are experienced at spotting inflated business deductions. If your Schedule C shows six figures in gross receipts but reports near-zero net income because of aggressive write-offs, expect the judge to look closely at whether those deductions are legitimate operating costs or personal expenses run through the business.

List Your Payroll Deductions and Withholdings

Most forms include a section for payroll deductions, which is separate from your monthly living expenses. This section matters because child support calculations in most states are based on net or adjusted income rather than raw gross income. Report the amounts shown on your pay stub for:

  • Federal and state income taxes actually withheld (not what you owe at tax time)
  • Social Security and Medicare taxes
  • Health insurance premiums, especially any premium you pay for your children’s coverage, which some states factor directly into the support calculation
  • Mandatory retirement contributions your employer deducts automatically (voluntary 401(k) contributions may or may not count depending on your state)
  • Union dues, if membership is a condition of your employment

Don’t inflate withholdings by claiming amounts you haven’t actually elected. The judge will compare your reported deductions against your pay stubs, and discrepancies undermine everything else on the form.

Break Down Your Monthly Expenses

The expense section asks what you actually spend each month. Forms typically organize this into categories: housing (rent or mortgage payment, property taxes, homeowner’s or renter’s insurance), utilities (electricity, gas, water, phone, internet), food, transportation (car payment, fuel, insurance, public transit), and personal costs like clothing and medical copays.

Two mistakes are common. The first is rounding everything up to make your financial picture look tighter than it really is. Judges and opposing attorneys compare your reported expenses against your reported income, and when the numbers don’t add up, it raises red flags. The second is forgetting to report only your share of shared expenses. If you split a household with a new partner or a roommate, report your portion, not the total bill.

Child-Related Expenses

Forms typically have a separate section for expenses tied specifically to the children. Childcare costs necessary for you to work or attend school are the big one, since many states factor this directly into the guideline calculation. Out-of-pocket medical expenses for the children — copays, prescriptions, orthodontia, therapy — go here too, along with school supplies, tutoring, or extracurricular costs if the form asks for them. Use actual receipts and statements wherever you can.

Why Accuracy Matters: Imputed Income

Federal law requires every state to establish child support guidelines and creates a rebuttable presumption that the guideline amount is the correct amount of support.2Office of the Law Revision Counsel. United States Code Title 42 – Section 667 The numbers on your declaration are the inputs that drive that formula. Inaccurate figures produce an inaccurate order, and fixing it later means filing a modification.

Underreporting is especially risky. If a judge believes you’re earning less than you could be — because you quit a well-paying job, turned down promotions, or aren’t working without good reason — the court can assign you an income figure based on your earning capacity rather than your actual earnings. That’s called imputed income, and it means the support order gets calculated on what you could be making. In some cases where a parent hasn’t worked in years and has no recent earnings history, judges assign at least a minimum-wage income. Exceptions exist for parents unable to work due to disability or serving as primary caregivers for very young children, but those situations require real evidence.

If you’re between jobs, document your job search. If you took a pay cut for a legitimate reason, be ready to explain it. Trying to look poorer on paper almost always backfires.

You’re Signing Under Penalty of Perjury

Your signature at the bottom of the form is a sworn statement that everything on it is true and correct.3Office of the Law Revision Counsel. United States Code Title 28 – Section 1746 Under federal law, anyone who knowingly makes a false statement under penalty of perjury faces up to five years in prison, a fine, or both.4Office of the Law Revision Counsel. United States Code Title 18 – Section 1621

Criminal prosecution is rare, but that’s not where the real risk lies. Judges who catch false or misleading information on a declaration routinely draw adverse inferences, meaning they assume you’re hiding even more than what was caught. Courts can also impose monetary sanctions and shift attorney fees to the dishonest party. Credibility with a family court judge matters in every contested issue that follows.

Redact Sensitive Information Before Filing

Your declaration will contain sensitive personal data: Social Security numbers, bank account numbers, and dates of birth for you and your children. Most courts have rules requiring redaction before filing. The typical approach is to show only the last four digits of Social Security numbers and financial account numbers, list only the birth year rather than full dates of birth, and use initials instead of full names for minor children.

Check your court’s specific redaction requirements before filing. If your court provides a confidential cover sheet or a separate form for sensitive identifiers, use it.

File the Form and Serve a Copy on the Other Parent

Once the form is complete, file the original with the court clerk. Most courts accept filings in person, by mail, or through an electronic filing system. Filing fees vary by jurisdiction. Some courts charge nothing for a financial declaration filed alongside a support motion; others charge a separate processing fee. If cost is a hardship, ask the clerk about a fee waiver application before filing.

After filing, you must provide a copy to the other parent, and you cannot hand-deliver the documents yourself. Another adult who isn’t part of the case must do it, either by personal delivery or by mail depending on your court’s rules. You can ask a friend or family member, or hire a professional process server. The person who delivers the papers then fills out and signs a Proof of Service form, which you file with the court to confirm the other parent received everything.

Update the Declaration When Things Change

Filing isn’t a one-time event. If your income or expenses change significantly after you submit the form — a job loss, a raise, new childcare costs, a jump in health insurance premiums — you may need to file an updated declaration. Courts expect current financial information, and outdated numbers can produce a support order that doesn’t reflect reality.

Even after a support order is in place, either parent can request a modification if circumstances have materially changed, and that process starts with a new financial declaration. Keeping organized financial records on an ongoing basis, not just when court papers are due, makes it faster and less stressful if you ever need to go back.
