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.


Slacklog does not require a dedicated app installed on a phone or computer because it is designed to run directly through a web browser. Here are several key reasons why Slacklog does not need a separate app installation:
  1. Web-Based Applications: Slacklog runs entirely within a web browser. Users don't need to download or install software on their devices because Slacklog's user interface and functionality are provided over the internet. Other examples include Google Workspace (formerly G Suite) applications like Google Docs and Google Sheets.
  2. Cross-Platform Compatibility: Slacklog works on various platforms and devices, including desktop computers, smartphones, and tablets. Users can access the same experience from different devices without needing platform-specific installations.
  3. No Local Storage or Processing: Web-based applications like Slacklog rely on cloud computing and remote servers for data storage and processing. Users interact with Slacklog through a user interface provided by the web browser, while the heavy lifting occurs on the application's server. This minimizes the need for local software installations.
  4. Ease of Updates: With web applications like Slacklog, updates and improvements can be made on the server-side, and users automatically benefit from the latest features and bug fixes without having to download and install updates manually.
  5. Accessibility: Web applications can be easily accessed from anywhere with an internet connection, making them highly accessible for users who need to work or use the software on different devices.
  6. Reduced Storage Requirements: Not having to install apps locally saves storage space on the user's device. This can be especially beneficial for users with limited storage capacity on their phones or computers.
  7. Lower Entry Barrier: Users can start using Slacklog almost immediately without the delay of app downloads and installations. They simply open a web browser and navigate to
  8. Cost-Efficient: Developing Slacklog for cross-platform use can be more cost-effective than creating and maintaining separate native apps for different platforms (iOS, Android, Windows, etc.).

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.
