Background
I've been married to my wife for eight years & live in Washington State. For that entire time, we've had separate bank and investment accounts, mostly due to inertia.
I make most of the money, and so I manage all of our finances out of my personal accounts. My wife isn't a finance geek like me, so her paychecks just pile up in her bank account until I log in under her name and do something with them. Usually that's moving them over to her Vanguard account and investing them. The vast majority of our total assets are in my accounts.
We both feel it would be better to merge our finances into single accounts. That way, I get a comprehensive view of our cash flow, it's easier for me to manage our finances, and she doesn't have to deal with any of this.
We already have a joint credit card, and we own our house under both of our names.
The question
What are the financial implications of merging accounts? I'm thinking about taxes, inheritance, etc.
Some examples of the things on my mind:
- Inheritance. If I die, my wife will have access to everything in any joint accounts, without hassle. We have a will, so she'd get the money anyway, but making the process easier is a perk. However...
- Capital gains. If I die, the cost basis for any investments I own will be stepped up when my wife inherits them. But as I understand it, that step-up is reduced by 50% on joint accounts. That's a potentially huge tax penalty. Conversely, if she dies before me and all the assets are in my personal accounts, I'll get no step-up at all, so the status quo also has some risk. I'm not sure I understand this fully, though.
- Making transactions. I imagine that if we have all our assets in joint accounts, we'll both need to sign off on some transactions (maybe just the big ones?). That will be added hassle for both of us. I'm not sure exactly how this would play out, though.
- Lawsuits. If someone sues my wife for whatever reason, AFAIK right now they can't go after my personal money (is this right?). If we have a joint account, they certainly could.
Is my understanding of these issues correct, and are there other issues I haven't listed above that could come back and bite us if we move forward with this?
(I'm also aware that if we decide to divorce, or if one of us gets in trouble with a collection agency or similar, joint accounts could pose problems. We're happily married, though, and our financial situation is very good, so I'm not worried about those types of issues.)
Approaches I'm thinking about
The simplest approach would be to create a joint checking account and a joint investment account. (In particular, "Joint Tenants with Rights of Survivorship" accounts, as described here.)
I could also create a joint checking account but keep my investment account for myself. Then my wife would have her paychecks go into the joint checking account, and I would move her money, along with my own, into my investment account from time to time. (AIUI, this would constitute a "spousal gift" and would not trigger any red flags with the IRS.) This might help with concerns about capital gains and inheritance.
There are also more elaborate options, like granting my wife the right to manage an account without making her an owner.
Related questions
There are several questions already about merging finances, such as these:
- Which practice to keep finances after getting married: joint, or separate?
- How to organize bank accounts with wife
The answers to these questions discuss practical concerns such as trusting one another, keeping money for personal expenditures, etc. My question isn't about that; it's about legal issues, tax implications, and so forth.
