Track shifts, business miles and expenses, keep an eye on your Tax Jar, and see the tax picture build as you work — without turning gig work into a bookkeeping job.
Add what you earned and the business miles you drove. GigJar keeps the tax picture organised underneath.
GigJar is designed around moments drivers already understand: a shift finished, miles driven, an expense paid and money put aside. The accounting and tax logic sits underneath rather than taking over the interface.
Log what you worked and what you earned. GigJar keeps recent earnings, hours and gross hourly rate together so you can see the working week clearly.
Record business mileage and additional expenses as you go instead of rebuilding the year from notes, statements and memory later.
GigJar compares the records you have logged with your current Tax Jar balance, helping you see whether the amount you have personally set aside is keeping pace with the estimate.
GigJar provides estimates and record-keeping tools, not personal tax advice.
Free should be genuinely useful. The core app is the manual foundation: record the work, understand the picture and keep clean records without needing a subscription.

Planned submission workflow based on records already kept in GigJar.
GigJar Pro is planned to use the day-to-day records already in the app to support the quarterly Making Tax Digital workflow for eligible users, avoiding the need to rebuild the same information in a separate bookkeeping product.
MTD and direct filing are in development. Availability will depend on completed product work and any HMRC recognition, authorisation or technical requirements that apply before launch.
