Frequently asked questions

EV Napló is an iPhone app for sole proprietors. It tracks your income and expenses, keeps your tax exposure and key limits in view all year, and prepares the numbers you need for your tax filing.

There's built-in, itemized calculation for átalányadó and vállalkozói szja: SZJA, social contribution tax, social security, and local business tax. KATA and other regimes can also be selected during setup, but without detailed tax calculation.

It depends on your annual revenue, costs, and withdrawal (kivét). Our guides include a calculator that compares átalányadó and vállalkozói szja using your own numbers, so you can see which one comes out ahead.

The goal is to let you handle day-to-day bookkeeping, recording income and expenses, and preparing the figures for your tax filing entirely on your own. In more complex situations, or if you're unsure about a tax question, it's still worth getting help from an accountant or tax advisor.

EV Napló is available on iPhone for now, with an Android version planned for a later date.

EV Napló is coming soon to the App Store. Sign up for the newsletter on the home page and we'll email you the moment it launches.
