The single most important thing is opening a separate business bank account before you do anything else. Do not run business income and expenses through your personal account. Keeping business and personal money apart makes your bookkeeping clean from the start, protects you if you ever get audited, and gives you an accurate picture of how the business is actually performing. Most banks offer free or low-cost business checking for small businesses.

Set up your bookkeeping from day one. Do not wait until you have “enough” transactions or until things get complicated. Every dollar in and every dollar out should be recorded from the first week. QuickBooks Online setup configured correctly at the start saves hours of cleanup work later and means you actually know where you stand financially as you grow.

Next, figure out whether you need to register for payroll taxes or sales tax. If you plan to hire employees, you will need to register with the IRS for a federal employer identification number and with your state for payroll tax withholding. If your service business sells taxable goods or if your state taxes certain services, you may need a sales tax permit. The requirements vary by state and business type, so check what applies in your situation.

Start setting aside money for taxes immediately. As a self-employed business owner, no employer is withholding taxes from your pay. A reasonable starting point is putting 25 to 30 percent of your net profit into a separate savings account for taxes. You will also need to make quarterly estimated tax payments to the IRS and likely to your state. Missing these payments or underpaying results in penalties and interest.

Finally, think about entity choice, but do not rush it. Most service businesses start as sole proprietorships or single-member LLCs taxed on Schedule C of your personal return. As your profit grows, an S-corp election might make sense to reduce self-employment tax. This is a planning conversation to have with a CPA after you have some operating history, not a decision you need to make in month one.

Getting these foundations right early makes everything easier down the road. Your small business bookkeeping stays clean, your tax obligations stay current, and you avoid the scramble that comes from trying to reconstruct a year of activity at filing time.
