Capital gains tax implications after moving from Maryland to Tennessee

You're asking a great question about a somewhat complicated situation! The good news is that capital gains taxation when moving between states isn't as confusing as it seems once you understand the basics. For federal taxes, your capital gains will be reported on your federal return regardless of where you live. Since you held the investments for more than a year (18 months), they'll be taxed at the long-term capital gains rate, which is currently 0%, 15%, or 20% depending on your income level. At 22 and just starting out, you might qualify for the 0% rate if your total taxable income is under the threshold. For state taxes, it gets a bit more complicated. Maryland does tax capital gains as regular income. However, Tennessee doesn't have an income tax or capital gains tax for individuals (they phased out their last investment income tax in 2021). You'll likely need to file a part-year resident return for Maryland, reporting the income you earned while living there. The capital gains would typically be allocated based on your residency status when you realized the gains (when you sold the stocks). Since you sold them after moving to Tennessee, they might not be subject to Maryland tax, but Maryland's specific rules would determine this. Your California-based employer doesn't affect how your capital gains are taxed - that's based on your personal residency, not your employer's location.

After reading about your situation, I wanted to share something that might help. I was in a similar position last year when I moved from New York to Florida and had to deal with capital gains across state lines. I was getting conflicting advice until I discovered taxr.ai (https://taxr.ai) which analyzed my documents and gave me clear guidance. For me, the problem was proving exactly when I established residency in my new state to determine which gains would be taxed where. I uploaded my lease, driver's license, and investment statements to taxr.ai and got specific advice about handling my part-year state returns. It showed me exactly which transactions fell under which state's tax rules based on my timeline. Made the whole process much less stressful!

Okay, I was skeptical about taxr.ai but decided to try it with my similar situation (moved from California to Nevada mid-year with stock sales). I was honestly surprised by how helpful it was! The document analysis feature immediately flagged that my brokerage statements still had my California address when I sold some shares, which could have caused problems proving my residency timeline. The advice was super specific - even told me exactly which California form to use for part-year residents and which line items would be affected by my capital gains. Saved me so much research time and potentially an audit headache! They even explained how the Nevada residency rules differed from California's and what documentation would best support my case if questioned.

For anyone dealing with state tax issues like this, another huge headache is actually getting through to someone at the state tax department who can answer your specific questions. I spent WEEKS trying to reach someone at the Maryland Comptroller's office last year for clarification on a similar residency question. After getting nowhere with endless hold times, I tried Claimyr (https://claimyr.com) and it completely changed the game. Their service called the Maryland tax office for me and navigated through all the phone menus, then called me when they had a real person on the line. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c It saved me literally hours of hold time and frustration. The Maryland tax rep I spoke with gave me the exact guidance I needed about reporting out-of-state capital gains after moving. Definitely worth it during tax season when the wait times are ridiculous.

I have to eat my words from my previous comment. After another frustrating morning of being disconnected twice by the Maryland tax line after 45+ minute holds, I tried Claimyr out of desperation. It actually worked exactly as advertised - I got a call back about an hour later with a real Maryland tax agent on the line. The agent confirmed that since I sold my stocks after establishing residency in my new state, Maryland wouldn't tax those specific gains. But she also warned me about maintaining too many ties to Maryland (like keeping my old doctor or having Maryland bank accounts), which could trigger them to consider me still a Maryland resident for tax purposes. This was exactly the clarification I needed and saved me potential tax issues. Really surprised this service exists and works. Definitely using it again next time I need to call any government office with notorious hold times.

Something nobody's mentioned yet - make sure you're keeping track of the COST BASIS of your investments properly! This matters way more than the state tax situation for most people. When I moved states, I was so focused on the state tax part that I almost forgot to properly account for some reinvested dividends in my cost basis. Would have overpaid by like $800! Make sure your brokerage has the correct purchase dates and amounts for everything you sold. Sometimes when you transfer investments between brokers during a move, this information can get messed up. Double-check their reported cost basis against your records before filing.

Just want to add a important warning: if you worked remotely for your California company while living in Maryland, you might have Maryland AND California income tax obligations for that portion of the year! California is super aggressive about taxing remote workers of CA companies. When you moved to TN, make sure you formally notified your employer of your new address and had them update your state tax withholding. Check your recent paystubs to confirm they're no longer withholding Maryland or California taxes.

Hey Diego! As someone who recently went through a similar multi-state move situation, I wanted to share a few practical tips that might help you navigate this. First, definitely gather all your documentation showing when you established Tennessee residency - lease agreement, driver's license change date, voter registration, etc. This timeline will be crucial for determining which state has taxing rights on your capital gains. Since you mentioned you're 22 and just starting out, there's a good chance your total income might qualify you for the 0% federal long-term capital gains rate (currently applies if your taxable income is under $47,025 for single filers in 2024). That could save you a significant amount on the federal side. For the state piece, you'll likely need to file as a part-year resident in Maryland for the period you lived there, but the capital gains realized after establishing Tennessee residency should escape state taxation entirely since Tennessee doesn't tax capital gains. One thing I'd recommend is keeping detailed records of when you physically moved, when you changed your address with various institutions, and especially when you updated your information with your brokerage. The timing of these changes relative to when you sold your stocks will matter if either state questions your residency status. Also, double-check that your brokerage has your current Tennessee address on file - you don't want tax documents being sent to your old Maryland address next year!
