What Business Tax Means & How to File It in 2025

Running a business means handling lots of things—sales, staff, supplies. But when it comes to business tax, it’s one task you can’t afford to skip. In 2025, filing business taxes the right way can help you stay out of trouble and save money. At Dreis Accounting Services, we help make taxes clear, simple, and stress-free.

Understanding Business Tax in 2025

Let’s start with what business tax is. It’s money your business pays to the government. This can be based on the money you earn, what you sell, or how many people you employ.

Here are a few types of business taxes you might need to pay:

  • Income Tax – This is a tax on your profits
  • Self-Employment Tax – For freelancers and sole owners
  • Payroll Tax – If you have employees
  • Excise Tax – Charged on certain goods or services

The purpose of business tax is simple: to help fund public services. In 2025, changes in deduction rules may affect your tax return, so it’s good to stay updated.

Common Business Tax Requirements in Washington State

If your business is in Washington, there are some unique taxes to know:

Business and Occupation (B&O) Tax

Washington doesn’t charge income tax like other states. Instead, it charges a B&O tax. This is based on your gross income, not profit.

Sales Tax

If you sell goods or services, you may need to collect sales tax from your customers. The rate depends on the location.

Federal Taxes

Besides state taxes, all businesses in Washington must file federal income tax. This includes self-employment or corporate income tax.

Entity Type Matters

Different business setups have different rules:

  • Sole Proprietors file on their return
  • LLCs may file as partnerships or corporations
  • S Corps and C Corps use different IRS forms

     

Knowing your entity type helps you figure out which business taxes apply.

Step-by-Step Guide to Filing Business Taxes

Here’s a full breakdown of how to handle business tax filing in 2025:

Gather All Income and Expense Documentation

Start with your receipts, invoices, 1099s, bank records, and bills. Keeping everything organized makes filing easier.

Reconcile Accounts Using Bookkeeping Software

Use tools like QuickBooks to check your numbers. Everything in your records should match your bank.

Determine Applicable Deductions and Credits

Look for what you can deduct:

  • Business meals
  • Equipment
  • Software
  • Health insurance (if self-employed)

Choose the Right Tax Forms and Filing Method

Match the forms to your business setup. Pick how you want to file—online, paper, or with help.

Calculate Your Tax Liability and Make Payments

Figure out how much you owe. Don’t forget the federal and state parts. Pay by credit card, ACH, or mail.

File on Time or Request an Extension

Don’t wait until the last minute. If you need more time, file an extension early.

Retain Records for Audit Protection

Keep your tax returns, receipts, and statements for at least 3 years. If you get audited, you’ll need them.

Tools & Resources for Business Tax Filing

Good tools save time and lower mistakes. Here are a few:

  • QuickBooks for taxes – For tracking income, expenses, and invoices
  • IRS e-File – For sending forms directly
  • WA Department of Revenue – For state business tax filing
  • Dreis Tax Checklists – Easy checklists for each business type

These tools keep you on track and make tax season smoother.

Mistakes to Avoid When Filing Business Taxes

  • Filing Late – Late returns mean fees
  • Wrong Math – Double-check your numbers
  • Forgetting Income – Yes, all of it counts
  • Skipping Deductions – Don’t leave money on the table
  • Not Saving Records – You’ll need them if audited

Getting help from a pro can stop these from happening.
