As the book closes on 2017, it’s time to time to think about taxes again. If you own a business, you will need to start preparing your paperwork soon. Whether you choose to hire a local accountant or not, this business tax return checklist provides an overview of what you will need to have in hand.

What you need for your Business Tax Return

The IRS requires that business owners have sufficient documentation for all income and expenses to support its business tax return. Even though you don’t need to submit all this information, you should have paper or electronic copies of all the following documents at your disposal.

Proof of Income

Income is the money a business receives in exchange for providing a good or service or through investing capital.

At the end of the year, you will need to compile these documents:

  • Gross receipts from sales or services
  • Sales records
  • Returns and allowances
  • Business checking/savings account interests
  • Other income

Cost of Goods Sold (if applicable)

  • Beginning inventory (total dollar amount)
  • Inventory purchases
  • Ending inventory (total dollar amount)
  • Items removed for personal purposes
  • Materials and supplies

  • Phones

  • Travel expenses (airfare, lodging, meals)
  • Commissions paid to subcontractors
  • Depreciation
  • Business insurance
