Start with these core documents

Medicaid applications require proof of identity, residency, and income. The exact documents vary by state, but most programs ask for a government-issued ID (driver's license, passport, or state ID card), proof you live in that state, and recent pay stubs or tax returns showing your household income.

You will also need your Social Security number and the Social Security numbers of anyone in your household you want to cover. If you do not have a Social Security number, you can still apply in most states, but the process takes longer because the state verifies your number through the federal system.

Bring originals or certified copies when you apply in person. If you apply by mail or online, most states accept photocopies or digital scans, though some ask you to bring originals later to verify.

Key Takeaways

  • You need a government ID, proof of state residency, and recent income documents (pay stubs, tax returns, or benefit statements) for nearly every Medicaid application.
  • Social Security numbers are required for everyone in your household you want to cover, though you can apply without one and provide it later.
  • Income limits and asset limits vary by state and by category (children, adults, seniors, people with disabilities), so what disqualifies you in one state may not in another.
  • Most states let you apply online, by mail, or in person at your local department of social services, and the method you choose affects how quickly you hear back.
  • If your situation changes after you apply — job loss, income drop, household size — you can report it and the state will recalculate your coverage without waiting for renewal.

Proof of income: what counts and what does not

Medicaid counts income from wages, self-employment, Social Security, unemployment benefits, child support, and most other regular money coming in. The state looks at your gross income (before taxes) in most cases, though a few states use net income instead.

Recent pay stubs (usually the last 30 days) are the fastest proof. If you are self-employed, the state wants your tax return from the last year plus bank statements or profit-and-loss records showing current income. If you receive Social Security, unemployment, or other benefits, bring the award letter or a recent benefit statement showing the monthly amount.

Some income does not count. Supplemental Security Income (SSI) is excluded in most states. Food assistance (SNAP) does not count. Child support you receive is usually counted, but child support you pay is deducted. The rules differ by state, so ask your local office what counts in yours.

Residency and citizenship requirements

You must live in the state where you apply. Proof of residency can be a utility bill, lease, mortgage statement, or mail from a government agency — anything dated within the last 60 days showing your name and address. A few states accept a signed statement from you if you cannot produce a document.

You do not have to be a U.S. citizen to receive Medicaid in most states. Lawful permanent residents (green card holders), refugees, asylees, and some other immigration statuses may have access to. Undocumented immigrants can receive emergency Medicaid in all states and full Medicaid in a few states (California, Illinois, New York, and Washington offer it to all low-income undocumented adults regardless of age). Bring whatever immigration documents you have — a green card, work permit, visa, or passport.

If you are not a citizen, the state will verify your status through federal immigration databases. This does not trigger deportation or immigration enforcement, but it does take extra time — sometimes two to four weeks longer than a citizen application.

Household composition and dependent information

List everyone living in your home, whether or not you want them on your Medicaid. The state uses household size to calculate your income limit. You will need the name, date of birth, and Social Security number for each person.

If you have children, bring birth certificates or adoption papers. If a child lives with you but you are not the legal parent, bring documentation showing your relationship — a custody order, guardianship papers, or a signed statement from the parent. Medicaid covers children in your household even if they are not biologically yours, as long as you claim them as dependents on your taxes or have legal custody.

If your household includes a spouse, you will need their income and Social Security number too. Some states count spousal income even if the spouse is not applying. A few states have different rules for married couples, so check with your local office.

Asset limits and what they mean

Most states have asset limits for Medicaid. An asset is money in a bank account, a car, a house, or other property you own. The limit varies: for a single adult, it might be $2,000 in one state and $10,000 in another. For families, limits are usually higher. Some states have no asset limit at all.

Your primary home and one car do not count toward the limit in most states. Retirement accounts like 401(k)s and IRAs are usually excluded. Life insurance does not count. The state counts cash, savings accounts, checking accounts, stocks, and rental property.

If you are over the asset limit, you may still be able to spend down — use the money for medical bills, home repairs, or other allowed expenses — and then apply. Some states let you set aside money in a special account for future medical costs. Ask your local office what options exist in your state.

Special situations: disability, pregnancy, and age

If you are applying as a person with a disability, bring medical records, doctor's letters, or disability award letters (from Social Security or Veterans Affairs). You do not need to be receiving disability benefits to may have access to for Medicaid as a disabled person — the state has its own definition.

If you are pregnant, you may may have access to for Medicaid even if your income is above the normal limit. Bring a letter from your doctor or midwife confirming the pregnancy and due date. Pregnant people often may have access to in the same month they apply, and coverage can start retroactively to cover medical bills from the previous three months.

If you are 65 or older, you may may have access to for both Medicaid and Medicare. Bring your Medicare card if you have one. Some older adults may have access to for Medicaid to help pay Medicare premiums and cost-sharing. The income and asset rules are usually more generous for seniors than for working-age adults.

How to submit your documents

Most states let you apply online through their Medicaid website or a portal like your state's benefits system. Online applications usually let you upload documents as PDF or image files. You can also apply by mail — print the application, fill it out, and mail it with copies of your documents to your local department of social services. In-person applications at a local office are fastest if you have all documents ready, because staff can tell you immediately if something is missing.

After you submit, the state sends you a notice saying they received your application and telling you what happens next. If documents are missing, they will send a request asking you to provide them within a set time — usually 10 to 30 days. If you miss the deadline, your application may be denied, but you can reapply.

Processing time varies. Online and in-person applications usually take two to three weeks. Mail applications take longer because of delivery time. Emergency Medicaid (for immediate medical needs) can be approved in one to three days.

What to do if your situation changes

After you are approved, report changes to your income, household, address, or immigration status within 30 days in most states. You can report changes online, by phone, or in person. The state will recalculate your coverage and send you a new notice.

If your income drops, you may become may be able to access for a higher benefit level or your cost-sharing may decrease. If your income rises above the limit, your coverage may end, but you will receive advance notice — usually 30 days — so you can appeal or look for other coverage. If your household size changes (a child is born, someone moves out), report it so the state adjusts your income limit.

Frequently Asked Questions

Do I need to bring original documents or are copies okay?

Copies are usually fine for the initial application, especially if you apply online or by mail. Some states ask you to bring originals later to verify. If you apply in person, ask the staff whether they need originals or copies before you go — policies vary by office.

What if I do not have a Social Security number?

You can still apply. The state will assign you an Individual Taxpayer Identification Number (ITIN) or use another identifier. Processing takes longer because the state verifies your number through federal systems. Bring whatever ID you have — a passport, visa, or state ID card.

Can I apply if I am homeless or do not have a permanent address?

Yes. Use a shelter address, a friend's address, a mailing address, or a general delivery address at your local post office. Bring mail addressed to that location or a letter from a shelter or social worker confirming where you stay. Homelessness does not disqualify you.

What happens if I submit documents and they are rejected?

The state sends you a notice saying which documents are unclear or missing and gives you a deadline to resubmit — usually 10 to 30 days. You can submit new copies, additional documents, or a written explanation. If you miss the deadline, your application is denied, but you can apply again.

Do I have to report my immigration status if I am undocumented?

Yes, you must answer the immigration status question on the application truthfully. Providing false information can result in denial and possible fraud charges. Reporting your status does not trigger immigration enforcement or deportation. The state uses the information only to determine Medicaid may be able to access.
