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.


In the United States, the deadline for most individual tax filers to submit their annual tax return is typically April 15th. However, this date can be adjusted if it falls on a weekend or a holiday. If April 15th is a weekend or a holiday, the deadline is usually extended to the next business day.

For example, if April 15th falls on a Saturday, the deadline would be extended to the following Monday. If April 15th falls on a Sunday, the deadline would also be extended to the following Monday.

It's important to note that tax deadlines can change, so it's advisable to check the IRS (Internal Revenue Service) website or consult with a tax professional for the most up-to-date information regarding tax filing deadlines and any extensions that may apply to your specific situation. Additionally, certain individuals or businesses may have different filing deadlines based on their circumstances, so it's essential to be aware of your specific filing requirements.

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.
