Sorry for delay in responding. I was not alerted that you had come back until this morning.
The amounts you paid for expenses of the business are not shown as income to the company.
You list the payments to the company from customers on the Schedule C as Gross but the expenses (even if paid by you from personal funds) are shown and subtracted.
You will be allowed to claim those expenses (paid from all sources of funding) and this may mean that you will have a loss on your bot***** *****ne.
In showing the loss you can deduct that from other income on the 1040. That will allow you to recoup the money you supplied yourself.
You are not going to show that $100k on the Schedule C as income at all. About the only place you will be listing this $100k would be on a bank statement but no where for tax reporting except to show expenses paid with it.
The profit or loss from this business flows back to you on the 1040, so all the money is yours actually anyway and no need to account for the amount you contributed (just the expenses that you paid for using those funds).
FREE EXTRA INFORMATION FOR YOU
A common accounting mistake small businesses make is not recording the source of checks deposited.
This is especially problematic if you're contributing the funds from your own money, because at the end of the year it may be difficult for you to determine which deposits were payments received for services, and which were from other sources (like your own pockets). Of course, you could sort this out by going through your personal accounts and records, but analyzing each deposit is time consuming.
To avoid this problem, simply write in your checkbook the source of each deposit, recording the payer and check number for each check. This will help keep your records straight at year end. If some deposits contain too many checks to notate separately in you check book, you'll have to write down the details on a separate piece of paper and record it along with your other checking account records.
Let me know if you need more information or additional help with that Schedule C or rating in a positive way is acceptable.
