When I taught a class about bookkeeping for creative entrepreneurs, my first rule was this-> -> Keep Them Separated. Keep your business income and expenses separate from your personal income/expenses. If you do this, filing taxes will be less of a headache.
Your business’s income is your income. This is completely counter-intuitive because when you start filing all of your LLC paperwork and setting up your business bank accounts and all of that, everyone will tell you to keep your business income/expenses separate from your personal income/expenses. Don’t let clients deposit paychecks into your personal bank account. Don’t put business expenses on your personal credit card; if you need to fund your business with personal income (and many new businesses do), transfer the money to your business bank account and record it as a capital contribution.
