Welcome to the Small Business Guides US hub. This is the starting point for owners, freelancers, contractors, 1099 workers, sole proprietors, and small teams that need clearer tax, expense, receipt, mileage, and filing records.
The guides focus on US federal filing and practical recordkeeping. For federal tax records, your system should clearly show income and expenses and keep supporting documents where you can retrieve them: IRS recordkeeping. If vehicles are part of your business records, MyCarTracks automatic mileage tracking can capture trips while you build the rest of the tax-year file.
Quick answer
Start with the tax overview if you need the big picture, the self-employed filing guide if you need forms, the deductions guides if you are sorting write-offs, the expense and receipt guides if you need proof, and the deadline guides if you need payment or filing dates. Keep mileage records with the same tax-year file when vehicles are part of the business.

Best first path
If you are just getting organized, read these in order:

- How to Claim Self-Employed Taxes (US)

That path gives you the main filing workflow first, then the record system that supports it.
Small business taxes start with records
Tax filing is easier when the records already exist. A useful small-business tax file should show income, expenses, receipts, mileage or vehicle use, tax forms, estimated payments, and notes for mixed personal and business costs.
The most important records usually include:
- Invoices and gross receipts
- 1099 forms and payment processor reports
- Bank and card statements
- Receipts, invoices, and paid bills
- Mileage logs and vehicle expense records
- Contractor, payroll, and employment tax records where relevant
- Estimated-tax confirmations
- Prior-year returns and carryforward notes
Good records also help during the year. They show whether the business is profitable, which expenses are rising, and whether you need to adjust pricing, quarterly tax payments, or vehicle policies.
Choose a guide by task
Use the tax-basics guides when you need to understand what to file or what taxes may apply. Use the deductions guides when you are deciding whether a cost may reduce taxable profit. Use the expense and receipt guides when the issue is proof. Use the deadline guides when the question is when and how to pay or file.
Vehicle-heavy businesses should pair these guides with the Mileage Guides library. Start with IRS Mileage Log Requirements, How to Track Mileage for Tax Deductions, and Standard Mileage Rate vs Actual Expenses when mileage, reimbursement, or vehicle costs are part of the file.
Build the tax-year folder
Use one folder for the tax year and one folder for each month. Store income reports, bank exports, receipts, mileage exports, invoices, statements, and tax payment confirmations in the month where they happened. At year-end, the return becomes a summary of records you already kept instead of a reconstruction project.
If you use MyCarTracks mileage tracking features, export business trips by month and save the report beside the month’s receipts and bank records. That keeps vehicle proof in the same workflow as the rest of the business expense file.
When to get professional help
These guides are educational and are not tax, legal, payroll, employment, or financial advice. Consider getting professional help when you have employees, inventory, multiple entities, large asset purchases, multi-state sales, sales and use tax, payroll tax, late filings, amended returns, or uncertain worker classification.
You should also get help when the records are incomplete and the deduction or filing position is material. Good guidance is easier and cheaper when the source documents are organized before the meeting.
MyCarTracks workflow
Use MyCarTracks for the vehicle side of your small-business record system: automatic trip capture, business and personal classification, notes, and monthly mileage exports. Store those exports with the same tax-year folder you use for receipts, bank records, estimated-tax confirmations, and filing notes.
