Frequently Asked Questions

Do you need to log your business miles for the IRS?

Slacklog is a mileage log generator.

It only takes 15 minutes to generate a printable mileage report for your annual tax return. It's private and secure.

The cost is $10 with a Credit or Debit Card.

You answer a series of questions, and it creates a mileage log. You will receive a minimally formatted XLSX file with pre-filled data you can customize in your preferred spreadsheet editor.

Why Slacklog?

Using a mileage log allows you to accurately track your vehicle-related expenses, including fuel, maintenance, insurance, and depreciation. This helps you claim the correct deductions and ensures you don't overlook any eligible expenses.


We believe that not storing customer information can be a wise decision for several compelling reasons, especially when considering data privacy and security. Here are some key advantages of this approach:
  1. Enhanced Data Privacy: By not storing customer information, we minimize the risk of data breaches and unauthorized access. This is crucial for protecting sensitive customer data, such as personal details and financial information, from potential security threats.
  2. Reduced Legal and Compliance Risks: Many regions and industries have strict data protection and privacy regulations, such as GDPR in the European Union or HIPAA in the healthcare sector. By not storing customer data, we reduce our exposure to compliance challenges and legal risks associated with data mishandling or breaches.
  3. Lower Security Overheads: Maintaining customer data requires robust security measures, which can be expensive and resource-intensive to implement and maintain. By avoiding data storage, we reduce the burden of securing sensitive information.
  4. Simplified Data Handling: Data storage involves not only securing data but also managing it throughout its lifecycle, including data retention and disposal. By not storing customer information, we simplify our data handling processes.
  5. Reduced Liability: In the event of a data breach or cyberattack, not storing customer information can limit our liability and financial responsibility for potential damages, legal actions, and reputational harm.
  6. Faster Development and Deployment: Designing software without the need to manage customer data can expedite the development process. We can focus on core features and functionality without the complexities of data storage and security.
  7. User Trust and Confidence: Users often appreciate when their data is not stored unnecessarily. This can help build trust and confidence in our software, especially in an era where data privacy concerns are paramount.
  8. Data Minimization: The principle of data minimization, a key aspect of data protection regulations, encourages collecting only the data necessary for the intended purpose. By not storing customer information, we align with this principle.
  9. Scalability and Efficiency: Software that doesn't store customer data can be more scalable and efficient, as it avoids the resource demands associated with large-scale data storage and processing.
  10. Faster Incident Response: In the event of a security incident or breach, we can respond more effectively when we don't have a trove of customer data to protect and notify affected parties about.
However, it's essential to strike a balance between not storing customer data and meeting the functional needs of our software. Some functions require minimal customer data for specific action (e.g., processing payments). In such cases, we follow best practices for data protection, secure data transmission, and regulatory compliance.

Deductions for Business Use

If you use your vehicle for business purposes, you can deduct the expenses related to that use. The Slacklog mileage log helps you track the number of miles you drive for business, which can be used to calculate your deduction. This can significantly reduce your taxable income and lower your tax liability.
