Be very careful with using the Hobby Loss rules - the IRS can be really picky if they pick you for an audit. From what you’ve stated, it sounds like it might be possible that you’re within the lines, but you probably ought to check with an accountant who’s had some experience in thes matters to make sure.
how did you solve the issue?
Sales tax is calculated on the price of what is being sold. So sales tax would be paid on the purchase price of the horse.
Income tax is calculated on income less expenses (very simplified explanation). The OP was mixing sales tax and income tax.
take note this is an OLD THREAD
OP has not been back for 4 1/2 years so guess we’ll never know how this went.
Hopefully not incarcerated for tax evasion!
