You've spent months narrowing down the list. Florida. Arizona. Portugal. Somewhere cheaper, warmer, closer to family. The move is the plan, and Social Security and Medicare are the financial foundation underneath it.
Most fears about relocation killing your benefits are overblown. Your Social Security check doesn't care where you live. Medicare Parts A and B travel with you anywhere in the country. But there are real things to know, especially if you have a Medicare Advantage or Part D drug plan, or if you're thinking about leaving the country entirely. A couple of details handled wrong can leave you with a gap in health coverage or a bigger tax bill than you expected.

Find out whether your new state taxes Social Security
Your benefit amount doesn't change when you move. The federal government calculates what you're owed based on your earnings history, and that number is fixed regardless of your zip code. What does change is whether your new state takes a cut of it.
Federal tax rules follow you everywhere: if your combined income clears certain thresholds, up to 85% of your benefits can be subject to federal income tax no matter where you live. State tax is a separate matter. As of 2026, only eight states tax Social Security benefits: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Every other state leaves Social Security income alone, including high-cost places like California and New York.
Among those eight, the reality is more nuanced than the list suggests. Colorado exempts benefits entirely for residents 65 and older. Connecticut only taxes benefits for individuals with adjusted gross income above $75,000 (or $100,000 for couples, with 75% of benefits exempt above that). Minnesota phases out its tax at moderate income levels. So even in the taxing states, most retirees of modest means won't actually owe anything. But if you're weighing a move from Ohio, which has no Social Security tax, to Montana, which applies rates up to 5.9% with limited deductions, it's worth running the numbers before you sign anything.
West Virginia finished phasing out its Social Security tax entirely in 2026, joining the majority of states. Kansas, Missouri, and Nebraska all eliminated theirs in recent years. If you're on the fence between two destinations, checking each state's current rules takes about ten minutes and can be worth real money every year you're retired.
What stays the same when you move
Original Medicare, Parts A and B, is a federal program. It doesn't have networks, service areas, or regional restrictions. If you move anywhere in the United States, your Part A and Part B coverage remains unchanged, as long as your new doctors and facilities accept Medicare assignment, which the vast majority do.
The one task you'll need to handle is updating your address. Medicare enrollment runs through the Social Security Administration, so you update your address with SSA, not directly with Medicare. You can do it through your My Social Security account online, by calling 800-772-1213, or by visiting a local SSA office. Skip this and your Medicare Summary Notice, billing, and any correspondence goes to your old address.
If you have a Medigap supplemental policy alongside original Medicare, the news is also largely good. Your insurer must allow you to keep the coverage when you move to a new state, though your premium may shift since Medigap pricing varies by location. The main exception is Medicare SELECT plans, which have localized provider networks. Moving out of a SELECT plan's service area means you'll need to switch.
Where Medicare Advantage and Part D get complicated
Medicare Advantage plans and Part D drug plans are sold by private insurers, and every one of them operates within a defined geographic service area drawn by county. Moving outside your plan's coverage area means you'll need to either find a new plan or return to original Medicare. A move within the same state can trigger this depending on the plan's footprint, so don't assume a state line is the only boundary that matters.
The enrollment window is tight. When you move out of your plan's service area, you qualify for a Special Enrollment Period. That window opens the month before your move and closes two months after. Notify your plan before you go and you get the early start. Wait until after you've moved to tell anyone, and the clock is already running against you. Either way, it closes two months post-move, full stop.
Part D drug plans follow the same rule. Even staying with the same insurance company, your specific plan may not cover your new area, and you'll need to re-enroll in one that does. Drug formularies, copays, and pharmacy networks can all be different under a new plan. Compare what's available at medicare.gov/plan-compare before you commit to a destination, not after. Enter your new zip code, list your medications, and see what you're actually working with.
One thing worth knowing if you're leaving a Medicare Advantage plan because of a move: you get a guaranteed issue right to buy a Medigap policy without medical underwriting. That window lasts 63 days from when your Advantage coverage ends. For people who've been locked out of Medigap due to health conditions, this is a real opportunity that won't come around again easily.
Moving abroad changes both programs significantly
Social Security handles international moves reasonably well. Medicare does not handle them at all.
If you're a U.S. citizen, Social Security will continue paying your retirement benefits regardless of where you move, with a short list of exceptions. The SSA cannot send payments to Cuba or North Korea. It generally cannot send them to Cambodia, Vietnam, or most former Soviet republics, though Armenia, Estonia, Latvia, Lithuania, and Russia are exceptions.
For nearly everywhere else, your monthly payment continues uninterrupted. Direct deposit is available in over 150 countries. If you're not a U.S. citizen, different rules apply based on your country of residence, and you'll want to check the SSA's Payments Abroad Screening Tool for your specific situation before making plans.
Medicare does not cover care received outside the United States, with very narrow exceptions for emergencies near the Canadian or Mexican border. If you have a medical event while living in Spain or Mexico City, you're paying out of pocket. Most people who retire abroad drop Part B, since it costs a monthly premium for coverage that can't be used.
If you qualify for premium-free Part A, be careful: you generally can't drop it without repaying all Social Security retirement benefits you've received, so that decision warrants a conversation with a financial advisor before you act on it. The practical solution for most expat retirees is a private international health insurance policy. In many countries, these plans are affordable, and they fill the gap Medicare leaves entirely open.
Before you move, run through this list
- Update your address with SSA immediately after moving. This covers both your Social Security account and Medicare mailing. Do it at ssa.gov/myaccount or call 800-772-1213.
- Check the Social Security tax rules in your destination state. If you're moving to one of the eight states that still tax benefits, find out whether your income level puts you above the exemption threshold.
- Confirm whether your Medicare Advantage or Part D plan covers your new area. Contact your plan directly or search at medicare.gov. Don't assume coverage in your current county extends to your new one.
- Compare plans in your new zip code before you move. Use the Medicare Plan Finder at medicare.gov/plan-compare. Doing this before the move gives you time to choose deliberately rather than scrambling during your enrollment window.
- If you're moving abroad, arrange private international health coverage before you go. Medicare won't cover you outside the U.S., and finding insurance after arriving in another country is harder and more expensive.
The process is manageable. The only real risk is assuming everything transfers automatically and discovering a gap in coverage after you've already moved.
