Help on ky sales tax return?
So a friend of mine owns a dog grooming business. She also sales accessories and pet food and things. On her sales tax return, does she only have to put total sales of the items she sold in her store? Or does line 1 have to include everything she earned including labor for grooming? So if you have to put total income what deduction description do you use for the grooming bsiness that don't accrue sales tax.
