LLC questions back accounts

[Alan Faitel]

my wife has a single-member LLC, and I have a single-member LLC.

Once in awhile, one or the other LLCs needs cash, Can one company write the other one a check? 

Or we have have to use are personal accounts to move the money around ?

@Alan Faitel , 
Yes, you can, but you need to account for them correctly in the LLC books.
Do you wanna treat the cash moved to another LLC as a business loan or just move cash without treating it as a loan. 

Most likely you will be inclined to not treat the cash movement as a loan because of other administrative issues ( such as interest calculation and interest income to the LLC)

If you dont want to treat the movement as a loan, then those cash movements would most likely be booked as distributions to a respective member of the LLC, ( husband in case husband's LLC), and the subsequent capital contribution from another member of another member to LLC ( wife's LLC). This is same as you withdrawing your money as distribution, giving it to your wife, and wife contributing to her LLC.

Generally, there is no tax implication for those movements. That would be one of the simple ways.
