Record Keeping

One of the fundamental aspects of preparing for your first small business tax filing is maintaining meticulous records. Accurate record keeping is crucial for documenting your financial transactions, income, and expenses throughout the year. Here's what you need to do:

a. Separate Personal and Business Finances: It's essential to open a dedicated business bank account and maintain separate financial records. Mixing personal and business finances can complicate your tax filings and potentially trigger an audit.

b. Keep All Receipts: Save all receipts related to business expenses, such as office supplies, equipment purchases, and travel expenses. These documents will serve as evidence of your deductible expenses.

c. Maintain Digital Records: In this digital age, consider using accounting software or apps to track your income and expenses. These tools can streamline the process and help you generate accurate financial reports.

Expenses Tracking

Tracking your business expenses is a crucial part of your tax preparation. Identifying deductible expenses can significantly reduce your tax liability. Some common deductible business expenses include:

  • Office Rent or Mortgage Payments
  • Utilities (e.g., electricity, internet, phone)
  • Employee Wages and Benefits
  • Marketing and Advertising Costs
  • Professional Fees (e.g., legal and accounting services)
  • Depreciation of Assets
  • Travel and Meals (subject to limitations)

By maintaining detailed records of these expenses, you can maximize your deductions and minimize your tax liability.

Due Dates

Small business tax deadlines are essential to ensure that you file your returns on time and avoid penalties. The due dates vary depending on your business structure:

  1. Sole Proprietorship or Single-member LLC: File your business taxes along with your personal taxes by April 15th.
  2. Partnerships and Multiple-member LLCs: File Form 1065 by March 15th. Individual partners' or members' tax returns (Form 1040) are due by April 15th.
  3. Corporations (C-Corps): The due date is generally April 15th. However, for fiscal year corporations, the due date may differ.

Mark these dates on your calendar, and consider seeking professional help if you anticipate any difficulties meeting these deadlines.

Hiring a Tax Attorney

Filing small business taxes for the first time can be overwhelming, especially as your business grows. To simplify the process and ensure compliance with tax laws, consider hiring a tax attorney. Here's how they can help:

  • Expertise: Tax attorneys are well-versed in tax codes and regulations. They can provide valuable guidance to help you make informed decisions and take advantage of available deductions.
  • Tax Planning: A tax attorney can help you develop a tax strategy that minimizes your tax liability while keeping your business in compliance with the law.
  • Representation: If you ever face a tax audit or dispute, a tax attorney can represent your interests and navigate the complexities of tax law on your behalf.


Filing small business taxes for the first time may seem like a daunting task, but with careful record keeping, diligent expense tracking, and attention to due dates, you can successfully navigate the process. Additionally, considering professional assistance, such as hiring a tax attorney, can simplify the process and ensure that you are taking full advantage of available deductions.
