Hungarian Tax & NAV Integration

Flat-rate taxation (átalányadó)

• Calculates SZJA (15%), SZOCHO (13%), and TB (18.5%) on a taxable base adjusted by your cost ratio.
• Supports the standard cost-ratio presets: 45% for most service businesses, 80% for retail, 90% for agriculture, matched against your annual tax-free personal allowance and the 18x minimum wage annual revenue ceiling.
• The Dashboard tracks your progress toward that ceiling all year, with a plain-language projection of when you'd reach it at your current pace, so you can prepare for filing rather than be surprised by it.

Sole Proprietor Income Tax (vállalkozói SZJA)

If you're on the profit-based system, EV Napló runs the full calculation:

• Your taxable profit (income minus recognized expenses) is taxed at the sole-proprietor tax rate (9% by default).
• On the after-tax profit you withdraw, it calculates personal income tax on the remainder, so you see the full combined tax burden in one place.
• The Dashboard tracks your accumulated taxable profit and estimated tax throughout the year, not just at filing time.

Other Hungarian tax systems

If neither of the above is your system, EV Napló still keeps the records your filing needs:

• Local business tax (iparűzési adó / HIPA): calculated at 2% by default, on income minus deductible expenses.
• KATA and other tax systems are supported as onboarding choices, without a computed breakdown.

NAV Online Számla sync

Connect your NAV technical-user credentials (tax number, login, signing key, exchange key) and EV Napló pulls your official issued and received invoice digests directly from the NAV Online Számla system. Invoices are automatically matched against your existing entries by client and amount, with a clear review list for anything unmatched, so nothing from NAV's records silently falls outside your books.
