Free Income Tax Tool for Small Business Owners (And the Financial Reports You Need for Q4 & Q1 Filing)

The fastest way to stay compliant during Q4 year-end prep and Q1 tax filing is to generate a tax-ready financial report using Adam by Tyms AI accounting software, then use a free income tax tool for small business to estimate what you owe.

Your financial report is what gives the IRS the exact proof of your income, business expenses, deductions, and taxable profit, without this, you can’t file correctly in Q1.

During Q4, every business must clean up their books, categorize their transactions, and prepare their final statements.

Then in Q1, those exact numbers are needed to prepare and file your federal and state income tax returns. This is where most business owners get stuck: their transactions are not categorized, their statements are incomplete, and they don’t have a proper Profit & Loss report to file taxes with.

Modern AI accounting software solves this by turning bank statements into a tax-ready financial report in minutes. And if you’re still unsure what you owe, a free income tax tool helps you estimate your liability instantly, based on the real numbers from your report.

What Financial Reports Do I Need for Q4 and Q1 Taxes?

To file small business taxes correctly, the IRS requires actual numbers. You’ll need:

Profit & Loss Statement (Income Statement)

This report summarizes your total revenue, deductible expenses, and net profit or loss for a specific period. It’s one of the most important financial reports every business should maintain.

For tax filing:

Schedule C (sole proprietors & single-member LLCs)
1120S (S Corporations)
1120 (C Corporations)
1065 (Partnerships)

The IRS requires you to report your business income and expenses, and the Profit & Loss statement is the report that provides these numbers.

While you don’t always submit a P&L as an attachment, you must have accurate income and expense records — which essentially come from your P&L — to correctly complete these tax forms.

In short: You can file taxes without attaching a P&L, but you cannot file correctly without the financial information that a P&L provides.

2. IRS-Ready Categorized Expenses (Required to complete your tax forms)

This is not an official IRS “report,” but it is required for accurate filing. You must categorize expenses using IRS labels like: Advertising, Office expenses, Utilities, Contract labor, Software subscriptions, Travel & meals, Rent, Insurance, Car/mileage, Depreciation, etc.

This is where AI outperforms manual bookkeeping. With Adam by Tyms, you don’t have to deal with the headaches of manual categorization, you can easily upload your bank statements and your transactions will be categorized in seconds.
