You'll find following options:
​

​

AI Tax Advisor

One of the quickest and most recommended ways is to contact our AI Tax Advisor. You can ask all your questions there and even upload pictures or documents

The AI Tax Advisor can (with your permission) read the info already in your app, like your expenses, revenues, and tax deadlines, so it can tailor the answer to you!

📍 Where to find it?

• Web: Support → AI Tax Advisor

• Mobile: tap the ✨ AI Tax Advisor icon in the bottom-right.

If you’re wondering “Is there a way I can deduct more things?”, open the advisor and ask: 👉 “What should I deduct that I’m not already deducting?”. You’ll then see a short permission pop-up → tap Allow this time ✅ to let it analyze your records and suggest what you’re missing.
​

​

🚀 When you open the AI Tax Advisor, you’ll see suggested prompts to get started. You can use one of these, but you’re not limited to them; you can ask tax, accounting, or app-related question.

✍️ Here are some tips to write great questions:

• 🎯 Be specific: add goal + period (e.g., “this quarter”, “for 2025”).

• 📝 Add context: activity, status (Self-employed/new S-E/student/one person company).

• 1️⃣ Ask one thing at a time when possible.

• ✅ Use action words: “list steps”, “give a checklist”, “estimate”.

If anything’s unclear or you’d like a human to double-check, you can always talk to one of our Tax coaches, we’ve got you 💜

Tax-Coaches

Another option is to contact our tax coaches. A chat box appears in the bottom-right corner, where you can start a conversation with one of them. Please note that it may take some time to receive a reply, as your questions are answered by real tax coaches, not AI. Once you receive a message, you’ll find it under the Messages tab.
