The California Medi-Cal RFTHI form — short for Request for Tax Household Information — is a document your county social services office sends when it needs to confirm who belongs in your tax household so it can decide whether you still qualify for Medi-Cal. You keep your coverage on track by identifying the person who will file the federal return, listing everyone that filer expects to claim as a dependent, and returning the signed form by the date printed on the cover letter.
Why the County Sent You This Form
Most Medi-Cal cases run on Modified Adjusted Gross Income (MAGI) rules, and MAGI cares about your tax household, not everyone at your address. Your tax household is the filer plus anyone the filer expects to claim as a dependent. The county asks for the RFTHI when that information is missing, out of date, or doesn’t match what the IRS or state employment records show.
The request usually shows up at your annual redetermination, after you report a change, or when the federal data hub flags a mismatch. Certain life events almost always trigger it: a child turning 19 (or 21 if a full-time student), a marriage or divorce, a birth, a parent moving in, or a jump in income that needs to be attributed to the right person.
A college student living away from home causes more confusion than any other situation. Under MAGI rules, people don’t have to share an address to share a tax relationship. A student who files their own return but still expects to be claimed by a parent is treated as a tax dependent, and the student’s Medi-Cal household is the parent’s household. A student nobody claims falls under the non-filer rules, and the household is built from the people actually living with the student. The RFTHI is where you tell the county which one applies.
Tax Household vs. The People Under Your Roof
The form makes sense once you know the three categories MAGI uses to build a household. Everyone gets sorted into one of them, and that placement decides whose income counts and how many people you’re counted as supporting.
- Tax filer. Your household is you plus every person you expect to claim as a dependent on your upcoming federal return. Your income counts, and so does the income of anyone in the household who is required to file.
- Tax dependent. Your household mirrors the taxpayer who claims you: that taxpayer, you, and the taxpayer’s other dependents. Exceptions apply if someone other than a parent or spouse claims you, or if you’re under 19 (under 21 if a full-time student) and your parents live together but file separately.
- Non-filer. If you neither file nor expect to be claimed, your household is the people who actually live with you: spouse, children under 19 (under 21 if full-time students), and, if you’re under those same ages yourself, your parents and siblings in the home.
Getting the category right matters. A larger household raises the income ceiling, and putting income under the wrong name can push a household over the limit or knock someone off coverage who should have kept it.
What To Gather Before You Start
Pull these together first so you’re not hunting for numbers while you fill out the form:
- Social Security numbers and dates of birth for every person you plan to include on your next federal return — filer, spouse if filing jointly, and each dependent.
- A current pay stub for each wage earner, a profit-and-loss statement for anyone self-employed, and records of other income such as unemployment or Social Security. The pay stub doesn’t have to be from the last 30 days, but it should reflect what you’re actually earning now.1Covered California. Proof of Income
- Your most recent federal tax return, so you can see who was claimed last year and note what’s changing.
- Your tax filing intentions for the current year: whether you plan to file at all, whether jointly or separately, and whether you’re adding or dropping any dependents.
Include dependents you expect to claim even if their paperwork isn’t finalized yet, such as a newborn, a newly adopted child, or a parent who just moved in.
Filling Out the Form
The RFTHI is built around your upcoming tax year, not last year’s return. That distinction is where most errors start.
Start with the tax filer. This is the person who will appear on line one of the 1040. If you’re married filing jointly, both spouses are filers. Fill in the filer’s name, Social Security number, date of birth, and relationship to the Medi-Cal applicant, and mark the expected filing status: single, married filing jointly, married filing separately, head of household, or qualifying surviving spouse. Head of household is a specific IRS filing status for unmarried filers who pay more than half the cost of keeping up a home for a qualifying dependent. It isn’t a general label for whoever runs the household.
Then list every dependent the filer expects to claim, with each person’s name, Social Security number, date of birth, and relationship to the filer. The form asks whether each dependent expects to file their own return. A dependent who files only to get back withheld taxes is still a dependent, so answering yes doesn’t automatically remove them from your household.2Internal Revenue Service. Dependents
Sign and date. Your signature attests that the information is accurate, so check every Social Security number and every spelling before you sign. Transposed digits are the single most common reason forms get sent back.
How To Submit It
You have three ways to return the form to the county:
- Upload through BenefitsCal. Log in at BenefitsCal.com, choose “Upload a Document,” pick the document type, attach a scan or clear photo of the signed form, and save the confirmation. This is usually the fastest, because it lands directly in your electronic case file.3BenefitsCal. Reporting Features Awareness Update
- Mail. Send the signed original to the address on the cover letter, using the return envelope if one came with it.
- Drop it off in person. Take it to your county social services office and ask for a date-stamped copy as your proof.
Keep a copy of the completed form and whatever confirmation you receive. If the county says later that nothing arrived, that copy is your evidence.
The Deadline and the 90-Day Cure Period
Your due date is on the cover letter that came with the form. During a redetermination or a request for more information, the county has to give you at least 20 calendar days to respond.4California Department of Health Care Services. Questions and Answers – Medi-Cal Annual Redeterminations Miss it, and the county can discontinue your Medi-Cal and send a Notice of Action explaining the termination.
That isn’t the end of the story. A 90-day cure period lets you send the information in after your benefits have already been cut, and if you’re found eligible, coverage is restored back to the discontinuance date with no gap. The cure period ends on the last day of the month in which the 90th day falls, and the exact date is on your discontinuance notice.5County of Santa Clara Social Services Agency. The 90-Day Cure Period The cure period only covers discontinuances tied to non-compliance during a redetermination or a change-in-circumstance review. It doesn’t apply to initial application denials or to people who asked to be taken off the program.
Even with the cure period in reserve, responding on time is easier than losing coverage and sorting out medical bills from the gap afterward.
What Happens After You Submit
An eligibility worker reviews the form and checks it against state and federal databases. The standard processing window for eligibility determinations runs up to 45 days, and during the annual redetermination cycle some counties use most of it.6County of Santa Clara Social Services Agency. Timeframes for Processing Applications
When the review finishes, the county mails a Notice of Action telling you whether coverage is continuing, changing, or ending, along with the effective date. Read it carefully. If you think the county got the household size or income wrong, you have 90 days from the date on the notice to request a state fair hearing. Past that window, you need to show good cause for the delay.7California Department of Social Services. Hearing Requests
Mistakes That Send the Form Back
A few errors cause most of the delays. Catching them before you submit saves weeks.
- Reporting last year’s tax household instead of the upcoming year’s. If you recently divorced, added a dependent, or stopped claiming a child who turned 19, the form should show the new picture.
- Leaving off dependents who live somewhere else. A college student, an out-of-state parent, or a child who splits time between homes can still be your dependent for tax purposes. If you plan to claim them, list them.
- Treating “Head of Household” as a description of who runs the house rather than an IRS filing status.
- Omitting income sources. The county checks employment and benefits databases; a side job you didn’t mention shows up as an inconsistency and triggers another request.
If You Need a Blank Copy
The county usually sends the form to you, so you rarely have to track it down. If you need one, you can pull it from the BenefitsCal forms page or ask your county social services office, which can also hand you one in person.8BenefitsCal.
