you elected S-Corp taxation for your LLC. unless you understand the tax rules with an S-Corp you would best use a pro to prepare the return for the first year. The return that must be filed is an 1120-S which if its using a calendar year will be due 9/15/2020. the start up expenses are to be reported on the return but no deduction is allowed for these expenses until the business actually starts operating. if this isn't until 2020 , that's the year these expenses will be deductible. some other things with an S-Corp. the need to take a reasonable salary (if operations don't begin until 2020 or are minor in 2019, the IRS probably won't say anything if no salary is taken in 2019) . thus payroll tax returns and a W-2 will need to be filed. have health insurance? proper handling is necessary if you want to get a deduction that reduces adjusted gross income. do it wrong and the insurance will only be deductible on schedule A as a medical expense. you are an employee of the S-Corp, and some states require that all employees be covered by workmen's compensation insurance. There are many more things that have to be considered. if you decide to do the return yourself, you will need a windows PC and buy the business TT software. you'll also need to use different TT software for your 1040.
