Married Couple - Open investment account Separate or Joined?
"I don't believe it makes a difference at the federal level -- if you file taxes jointly, gains, losses, and dividends appear on the joint tax account.  If you file separately, I assume the tax implications only appear on the owner's tax return.  Then the benefits might outweigh the costs, but only if you correctly predict market behavior and the behavior of your positions. For example, lets say you lose 30k in the market in one year, and your spouse makes 30k.  If you're filing jointly, the loss washes out the gain, and you have no net taxes on the investment.  If you're filing separately, you can claim 3k in loss (the remaining 27k in loss is banked to future tax years), but your spouse pays taxes on 30k in gain. Where things get more interesting is at the state level.  I live in a ""community property state,"" where it doesn't matter whether you have separate accounts or not.  If I use ""community money"" to purchase a stock and make a million bucks, that million bucks is shared by the two of us, whether the account is in my name our in our name.  income during the marriage is considered community property.  However property you bring into the marriage is not.  And inheritances are not community property -- until co-mingled. Not sure how it works in other states.  I grew up in what's called an ""equitable property state."""
"I will expand on Bacon's comment. When you are married, and you acquire any kind of property, you automatically get a legal agreement.  In most states that property is owned jointly and while there are exceptions that is the case most of the time.   When you are unmarried, there is no such assumption of joint acquisition.  While words might be said differently between the two parties, if there is nothing written down and signed then courts will almost always assume that only one party owns the property.  Now unmarried people go into business all the time, but they do so by creating legally binding agreements that cover contingencies.  If you two do proceed with this plan, it is necessary to create those documents with the help of a lawyer.  Although expensive paying for this protection is a small price in relation to what will probably be one of the largest purchases in your lives. However, I do not recommend this.  If Clayton can and wants to buy a home he should.  Emma can rent from Clayton.  That rent could any amount the two agree on, including zero.  If the two do get married, well then Emma will end up owning any equity after that date.  If they stay together until death, it is likely that she (or her heirs) will own half of it anyway.  Also if this house is sold, the equity pass into larger house they buy after marriage, then that will be owned jointly. If they do break up, the break up is clean and neat.  Presumably she would have paid rent anyway, so nothing is lost.  Many people run into trouble having to sell at a bad time in a relationship that coincides with a weak housing market.  In that case, both parties lose.   So much like Bacon's advice I would not buy jointly.  There is no upside, and you avoid a lot of downside. Don't play ""house"" by buying a home jointly when you are unmarried." It should be in the name(s) of whomever puts money in the account.  When filing your taxes there will be a question or space to mark the percentage of income in each others name. If you're just looking for small amounts of income splitting, then it's legal for the higher earning spouse to pay household expenses and then the lower earning spouse can save all or some of his/her income. Whether or not to have 2 accounts or not has more to do with estate planning and minimizing account fees if applicable.  It can also help in a small way for asset allocation if that's based on family assets and also, minimizing commissions. "I can only share with you my happened with my wife and I. First, and foremost, if you think you need to protect your assets for some reason then do so. Be open and honest about it. If we get a divorce, X stays with me, and Y stays with you.  This seems silly, even when your doing it, but it's important. You can speak with a lawyer about this stuff as you need to, but get it in writing. Now I know this seems like planning for failure, but if you feel that foo is important to you, and you want to retain ownership of foo no mater what, then you have to do this step. It also works both ways. You can use, with some limitations, this to insulate your new family unit from your personal risks. For example, my business is mine. If we break up it stays mine. The income is shared, but the business is mine. This creates a barrier that if someone from 10 years ago sues my business, then my wife is protected from that. Keep in mind, different countries different rules. Next, and this is my advise. Give up on ""his and hers"" everything. It's just ""ours"". Together you make 5400€ decide how to spend 5400€ together. Pick your goals together. The pot is 5400€. End of line. It doesn't matter how much from one person or how much from another (unless your talking about mitigating losses from sick days or injuries or leave etc.). All that matters is that you make 5400€. Start your budgeting there.  Next setup an equal allowance. That is money, set aside for non-sense reasons. I like to buy video games, my wife likes to buy books. This is not for vacation, or stuff together, but just little, tiny stuff you can do for your self, without asking  ""permission"". The number should be small, and equal. Maybe 50€.  Finally setup a budget. House Stuff 200€, Car stuff 400€. etc. etc. then it doesn't matter who bought the house stuff. You only have to coordinate so that you don't both buy house stuff. After some time (took us around 6 months) you will find out how this works and you can add on some rules. For example, I don't go to Best Buy alone. I will spend too much on ""house stuff"". My wife doesn't like to make the budget, so I handle that, then we go over it. Things like that." "My wife and I use to file ""married file separately"".  I consulted a tax accountant and it does not matter who's name the accounts are under.  The interest from the accounts can be counted as income on either person's tax return regardless of whose name is on the account.  You can even split the interest income between the returns if that is advantageous.  This is true for any income earned between the two of you. It use to be a big hassle to file this way even using the software programs.  The programs would not attempt to allocate the income between the tax returns in order to minimize my tax liability.  I had to do this manually.  Most of the loopholes have been closed and the last couple of years I've filed ""married filed jointly"". I'm not sure how your wife's citizenship status affects any of this." Do you have a spouse? You can contribute to a spouse's IRA if you guys are filling a joint tax return A share of stock is an asset not much different than any other asset.  If the share is being held in a joint account, it's being jointly owned.  If the share is being held by a company with multiple owners then the share is owned by the various owners.  If you're married and in a community property state, then it's technically owned by both parties. From the FAQ I think it is fairly clear that it is OK: Can I open a Help to Buy: ISA with someone else? No. Help to Buy:   ISAs are only available to individuals. But, you can put more than one   government bonus towards the home you are buying. So, if you are   buying a home with someone else who is also a first time buyer, they   can open and save money into their own account and receive a   government bonus. Inference: if you are buying a home with someone else who is NOT also a first time buyer, they can't get their own account and get the bonus (but there's no problem with you doing so).  Alternatively - open the Help To Buy ISA, you'll still get the normal interest rate on it, and then argue the case with the conveyancer / solicitor once you actually buy the property and claim the Government bonus. In fact, here is the declaration you (well, specifically, your girlfriend) would have to sign at the point you jointly make the purchase. Nothing in there that forbids it being a joint purchase with a non-first-time-buyer either. Congrats! Make sure you nail down NOW what happens to the house should you eventually separate. I know lots of unmarried couples who have stayed together for decades and look likely to do so for life; I've also seen some marriages break up that I wouldn't have expected to. Better to have this discussion NOW.  Beyond that: Main immediate implications are that you have new costs (taxes, utilities, maintenance) and new tax issues (mortgage interest and property tax deductability) and you're going to have to figure out how to allocate those between you (if there is a between; not sure whether unmarried couples can file jointly these days). I feel there are two types of answer: One: the financial. Suck all the emotion out of the situation, and treat the two individuals as individuals. If that works for the two of you, fantastic. Two: the philosophical. You're married, it's a union, so unify the funds. If that works for you, fantastic. Personally, my partner and I do the latter. The idea of separate pots and separate accounts and one mixed fund etc makes no sense to us. But that's us. The first step for you in deciding on an approach is to know yourselves as people - and everything else will follow. "It depends on when, where and how the account was setup.  If the state has an UGMA (Uniform Gift to Minors) law, the account was probably opened under that -- in which case, your wife became the custodian by statute at age 18 or 21. She has always been the account owner. The ""catch"" is that if your wife's father died before she assumed custodianship of the account, it may be subject to taxation. You may be in some sort of oddball situation where due to your wife moving, the broker merging or lost records, the phone reps cannot figure out what is going on. I'd suggest working the phone tree a little harder and searching for old records." I agree with Option 3 from the accepted answer (His/Hers/Joint), but with one caveat (that my wife and I are finding out). Once you have children, if your income is in the mid-range where you are not paycheck to paycheck, but are not floating in excess money either (ie, you can have a vacation, but you have to plan for it and save up for a few months to do so), the child-relative expenses begin to be a huge factor in your overall budget, such that (particularly if one partner does more of the child-related buying) it can be hard to really keep up the 3 account separation, because those child-related expenses may end up being all of one earner's paycheck. We originally did the 3 way split, where we took rent, car, and utilities from joint (ie, each transferred a reasonable portion to the joint account to cover), and just bought groceries each occasionally such that it was generally a reasonable split (as we both shopped for groceries and both earned close enough to each other that it worked out).  But once we had kids, it ended up being very different, and we eventually had to more properly budget all of our funds as if they were basically joint funds.  While we still do have separate accounts (and, largely, separate credit cards/etc., except for one joint card), it's almost pro forma now due to the kids. "From what you've described, your spouse is a non-resident alien for US tax purposes. You have two choices: Use the Nonresident Spouse Treated As Resident election and file as Married Filing Jointly. Since your spouse doesn't have, and doesn't currently qualify for, an SSN, he/she will need to apply for an ITIN together with the tax filing. Note that by becoming a resident alien, your spouse's worldwide income the whole year would be subject to US taxes, and would need to be reported on your joint tax filing, though he/she will be able to use the Foreign Earned Income Exclusion to exclude $100k of her foreign earned income, since he/she will have been out of the US for 330 days in a 12-month period. Or, file as Married Filing Separately. You write ""NRA"" for your spouse's SSN on your tax return. As a nonresident alien, if your spouse doesn't have any US income, he/she doesn't have to file a US tax return, and doesn't need to apply for an ITIN. Which one is better is up to you to figure out." I started out thinking like you but I quickly realised this was a bad approach. You are a team, aren't you? Are you equals or is one of you an inferior of lower value? I think you'll generate more shared happiness by acting as a team of equals. I'd pool your resources and share them as equals. I'd open a joint account and pay both your incomes directly into it. I'd pay all household bills from this.  If you feel the need, have separate personal savings accounts paid into (equally) from the joint account.  Major assets should be in joint names. This usually means the house. In my experience, it is a good idea to each have a small amount of individual savings that you jointly agree each can spend without consulting the other, even if the other thinks it is a shocking waste of money. However, spending of joint savings should only be by mutual agreement. I would stop worrying about who is bringing in the most income. Are you planning to gestate your children? How much is that worth? - My advice is to put all this aside, stop trying to track who adds what value to the joint venture and make it a partnership of equals where each contributes whatever they can. Suppose you fell ill and were unable to earn. Should you wife then retain all her income and keep you in poverty? I really believe life is simpler and happier without adding complex and stressful financial issues to the relationship. Of course, everyone is different. The main thing is to agree this between the two of you and be open to change and compromise. If it makes your finances easier, why not? My wife and I had his/hers/our since before we were married. I also have an account to handle transactions for my rental property, and one extra for PayPal use. I was paranoid to give out a checking account number with authorization for a third party to debit it, so that account has a couple hundred dollars, maximum. All this is just to explain that your finances should be arranged to simplify your life and make you comfortable. Post-tax (i.e. non-retirement account) investing is nothing to ignore. You don't mention a spouse, so for a start, you still have the $5500 to put in an IRA.  The remaining investment funds will earn dividends, if any, at a tax preferred rate, and then the gain on sale will be taxed at 15% if the code doesn't change again. The gains accumulate tax deferred, and you control the timing of the sale. With a 401(k) all withdrawal are taxable as income. In your case, just the gain is taxed at a potential long term cap gain rate. Hopefully the new job pays more than the old one and the loss of 401(k) is compensated.
