Can someone who has 2 sole proprietorships share a single credit card processing device to save on processing fees? What would be proper way to file taxes in such case?

Basically, my concern is that there would be single 1099-k form coming from the credit card processing company and the number reported on it would not have exact match on either of the two Schedule C individually (aggregate would be fine though). If this is something permissible, then what is correct way to do that:

  1. Should one not use DBA name (or EIN) with credit card processing company so it would not map to particular Schedule C?
  2. Should one sole proprietorship issue 1099-MISC form to other sole proprietorship to split the income reported on 1099-k?
  3. Should owner keep some records on which transactions should be reported on the first Schedule C and which on the second Schedule C in case of IRS audit?
  • Is there a particular reason you've chosen sole proprietorship rather than an LLC or corporation? It seems that you might want to do that just to protect yourself legally from anything that happens with your businesses.

    Something that might shortcut the question - What does your contract with the processor say? Can you as a sole proprietor run cards for another company whether you own it or not? Did you sign up to the processor as you or your company? If your question is specifically focused on the tax implications and not the broader issue of sharing, please edit the title to reflect that.

  • @Freiheit Yes this question is asked from taxes point of view. Both sole proprietorships are mine. Apr 15, 2021 at 16:58
  • What is a "sole proprietorships" ?

  • SRN, LLCs as such achieve: absolutely nothing. For tax, they're completely pass through and for liability they have no shelter. I guess some sort of Corp. would be what you're envisaging there ?

Other than having two schedule C's your tax situation is no different than if you had one sole proprietorship. You file one Schedule SE that combines the income from all Schedule C's and you report combined profit/loss on your 1040.

How it gets reported/divided across Schedule C's is not something I am incredibly confident of but I have seen similar situations with 1099's issued to one spouse instead of a joint business. My understanding is that in general you should match any received forms to the appropriate SSN/EIN. So, if the 1099-K was issued to a specific EIN then it should be reflected on the Schedule C for the business with that EIN, and you'd account for the portion that belongs to the other company by entering an item in Part V, Other Expenses.

The other expense entry would be something like:

Income assigned to Nominee - OtherBusinessName - OtherBusinessEIN

Then you record that amount as revenue to your other Schedule C and you've got the 1099-K properly matched to the right Schedule C and you've accounted for the revenue that doesn't apply to that company.

If the 1099-K is issued to your SSN and your businesses have EIN's then the cleanest approach might be a third Schedule C with multiple income assignments.

Hopefully others weigh in if anything I've stated is flawed. If you haven't yet set up your businesses there are a number of good articles on how to organize multiple businesses under one parent/holding company that should help. Also, as others mentioned, understand the terms of your merchant agreement(s) to see if this is even permissible.

First and foremost, I would STRONGLY suggest that you choose something other than sole proprietorship for your businesses unless you have compelling reasons not to do so (nothing comes to mind immediately, so I'm at a bit of a loss there).

Second, whether you can process cards from more than one business through the same merchant account is questionable, depending on the nature of each business. For instance, when you applied for a merchant account, you had to specify the nature of your business, as well as the type and average amount of card transactions you anticipate running. The processor then makes their determination based on that information. So if the second business you have is radically different (say, maybe you opened the account for your bicycle business and now have a new internet-based venture of some kind) then it changes the risk model (and very frequently the rate you pay) for card processing services.

As noted by another comment, your merchant agreement might preclude you from using your account for any business other than the one you originally signed up for, so you may have to sign up for a separate merchant account for the new business. That will be the most significant issue at the moment.

As for the tax implications, your question makes the case why you might want to create legally separate entities so that you can file taxes for each one and keep your personal taxes cleaner.

    I haven't dived into LLC subject too much, but my understanding is that 1) Some states have LLC fee which makes operating LLC more expensive 2) more tax forms have to be filed with IRS and sometimes state tax boards 3) not sure about insurance rates for a similar LLC - wouldn't insurer ask more to insure LLC than similar Sole proprietorship as insurance company takes more risks? 4) if you are insured with CGLI then does LLC still add a lot of added value? 5) I don't think LLC helps with IRS problems in case of mishap, does it?

  • Well put, user389238. LLC fees and taxes in some states effectively discourage the use of the LLC structure. The corporate structure, whether C or S, adds lists of chores for you to comply with. A sole proprietorship, perhaps with a fictitious business name registration, is a viable alternative. Apr 15, 2021 at 17:31
  • The additional documentation is always something to think about, as might be extra costs, however you must also consider the fact that as a sole proprietor, your personal assets are at risk if your business is sued. Further, if you use an LLC or S corp, you can take a portion of your compensation in the form of a distribution, which is taxed at capital gains rate rather than as personal income, which might offset the additional costs. A few states, like CA, charge annual LLC fees, but not all (or many, actually).

  • @orange coast, what's the "reinstate monica" thing? (grin) I've seen it elsewhere but am VERY curious what it's about!

  • @SRiverNet LLC is no different from sole proprietorship to the IRS unless an election has been made to tax the LLC as Corp, so you can't take a portion of compensation as distribution just by virtue of having an LLC. Whether or not personal assets are at any real risk depends on the nature of the business and the insurance coverage.
