Frequently Asked Questions
Everything you need to know about calculating your Schedule C deductions
How accurate is the OCR technology?
Our AI-powered OCR has a 98%+ accuracy rate for receipts under ideal conditions. It can read handwritten receipts, faded ink, and even crumpled documents. Any uncertain data is flagged for your review, so you can verify accuracy before filing.
Can I use this if I have multiple vehicles?
Absolutely! DeductMax handles multiple vehicles seamlessly. If you have 5 or more vehicles used in your business, the IRS requires you to use the actual expense method—we automatically detect this and ensure compliance while maximizing your deduction.
What format should my mileage data be in?
We accept CSV files with Date, Miles, and Purpose columns. We're compatible with all major mileage tracking apps including MileIQ, Everlance, TripLog, and Stride. You can also use your own spreadsheet—just make sure it has those three columns.
Is the $27 a one-time payment or subscription?
It's a one-time payment per Schedule C line calculation. No subscriptions, no recurring charges. You pay $27 for Line 9 (Car and Truck Expenses), complete your calculation, download your reports, and you're done. If you need to recalculate later in the year, you can start a new session for $27.
How long does the calculation process take?
Most users complete the entire process in under 10 minutes. Upload your mileage CSV (30 seconds), upload receipts (1-2 minutes), review any flagged items (1-2 minutes), and get your results instantly. The OCR processing is incredibly fast—we can process 100 receipts in under 60 seconds.
Will this work with my tax software?
Yes! DeductMax generates a detailed PDF report with all calculations, supporting documentation, and the exact number you need for Schedule C Line 9. Simply enter this amount into TurboTax, H&R Block, or give the report to your CPA. The report includes all IRS-required documentation for audit protection.
What if I made a mistake or forgot some receipts?
You can upload additional receipts at any point before finalizing your calculation. The system recalculates automatically. If you've already completed a session and discover missing expenses, you can start a new session for $27 with the complete data.
Do you offer support if I have questions?
Yes! All users receive email support. We typically respond within 24 hours on business days. Our team can help with technical issues, answer questions about HOW TO USE DeductMax, and guide you through the process if you get stuck. We cannot provide tax advice—please consult a CPA for tax-specific questions.
