Photo the letter — I'll tell you what's in it.
Three clear steps, all year round.
Photo a receipt. Import a bank statement PDF. Tap in your income in two seconds. Restio recognizes it instantly: what it is, whether you can deduct it, and how much tax you'll save — all current for 2026. For larger purchases, Restio splits the depreciation over the right years automatically.
Letter from the Finanzamt, big purchase decision, Kleinunternehmer threshold, parental leave, crypto — for every important tax topic, Restio walks you step-by-step through the right flow. With paragraph, deadline, and number. And if you just ask freely, Restio recognizes your topic and routes you there automatically. It remembers what matters to you — for every next question.
Monthly and yearly reports. EÜR-Dossier for freelancers, ELSTER summary, or CSV for your tax advisor. On top: Restio reaches out before a deadline runs out or you cross a threshold — Werbungskosten flat rate, Kleinunternehmer §19, home office cap, advance payments. Year-round, not just in March.
ChatGPT invents the journey every time. Restio already knows it — from a letter from the Finanzamt to the Kleinunternehmer threshold, from a big purchase decision to parental leave.
For every topic there's a clear flow: which question first, which paragraph applies, which deadline matters, which number decides. Restio walks you through, step by step — and never jumps to something it doesn't know yet.
You can tap a topic, or just ask freely. Restio recognizes what you mean and routes you to the right path automatically. You never have to find it yourself.
While you go about your day, Restio watches in the background: your receipts, your income, your thresholds, your deadlines. The moment something moves close to a limit, you hear about it — before it's too late.

Tap any alert — you land directly in a guided conversation for that exact topic, with all the relevant numbers and options.
Take a photo of your receipt. Restio reads out the amount, vendor, date and category — and tells you, in the same second, whether it's deductible and how much tax you save with it. In euros. Based on your tax class, your state, and your income. Not 'maybe', not a generic percentage.
Abschreibung — automatisch richtig
Bank statements work too: upload a PDF and Restio categorizes every transaction in one pass. You only confirm the uncertain cases — the rest runs in the background.
The first time, Restio learns your profile — profession, state, tax class. From then on, you never have to explain it twice. Restio remembers what's tax-relevant for you — your open topics, your recent purchases, your recurring questions — and gets straight to the point next time.
Every receipt you photograph. Every Finanzamt letter you upload. Every conversation you start. Everything stays organized by topic in your history — findable weeks or months later. Over the course of the year, you build up a complete archive without sorting anything yourself.
And you stay in control: view, export, or delete everything — anytime, with a tap.
Tap the mic and start talking. Restio listens, pauses to think, and then speaks back — like a real conversation. You can interrupt, share a document, switch the topic. It's not a dictation feature.
Practical when you don't have a free hand — in the car, in the kitchen, while sorting receipts at the table. You speak, Restio replies, you keep going.

Upload a photo — Restio tells you what's in it and which deadline matters.
Enter days and kilometers — Restio calculates the full allowance for you.
Six euros per day, up to the cap. Restio tracks the days.
Restio finds the items you usually leave behind — receipt by receipt.
Married? Combine both profiles — Ehegattensplitting calculated correctly.
Restio reads the assessment with you, checks the flat-rate caps, and tells you whether an Einspruch is worth it — deadline included. Commuter allowance, home office, Werbungskosten: all current for 2026.
Restio sorts your receipts all year, watches the Kleinunternehmer threshold, and packs a ready EÜR dossier at year-end — for ELSTER or your tax advisor.
Restio explains the German system in English, asks only what's relevant to you, and walks you through your first assessment step by step. Double taxation and moving abroad are also covered.
What Restio does differently — and better.
Restio isn't a filing tool. You file through ELSTER or Taxfix/WISO yourself — Restio prepares you for it all year long.
Whatever you share with Restio, you control.
Restio only asks what your current topic actually needs. Nothing is collected in the background that you didn't share yourself.
Your profile, your history, your receipts, what's remembered about you — all visible in one place. No hidden drawers.
One tap: a clean export — for ELSTER, your tax advisor, or just yourself. Whenever you want.
Individual receipts, individual topics, or your whole account — no waiting, no questions. Gone is gone.

Die Homeoffice-Funktion ist Gold wert
Arbeite von zuhause und hatte keinen Plan wie man die Homeofficez - Pauschale berechnet. Restio hat mich Schritt für Schritt durchgeführt. Hab gemerkt dass ich Geld liegen lasse.

Perfekt für Leute die Papierkram hassen
Ich bin eine Katastrophe wenn es um Finanzunterlagen geht. Jetzt scanne ich einfach alles wenn es reinkommt und Restio sortiert das. Kein Schuhkarton voller Belege mehr am Jahresende.

Gut aber noch am Anfang
Man merkt dass die App noch wächst aber der Kern ist solide. Die KI-Antworten sind hilfreich und soweit ich das beurteilen kann auch korrekt. Bin gespannt wie es weitergeht.

Besser als gedacht
War skeptisch wegen noch einer KI-App aber die kennt sich echt gut mit deutschem Steuerrecht aus. Hab ein paar knifflige Fragen zu Werbungskosten gestellt und solide Antworten bekommen.

Rettung für Freiberufler
Bin freiberufliche Designerin und Steuern stressen mich jeden Monat. Restio hilft mir den Überblick zu behalten was ich ausgebe und ob es steuerlich relevant ist. Deutlich weniger Angst jetzt.

No. Restio is with you year-round — answers questions, sorts receipts, watches thresholds and deadlines. For the official filing you still need ELSTER or a tax advisor. Restio prepares everything so both paths are faster.
Answer your tax questions in plain language — based on your tax class, state, and situation. Photograph receipts, import bank statement PDFs. Guided flows for every important tax topic, from the Kleinunternehmer threshold to a Finanzamt letter. Reminds you before you miss a deadline or cross a threshold. At the end: a clean package for ELSTER or your tax advisor.
No. Restio is built for people who don't want to spend their lives on taxes. You describe what's going on — in normal words. Restio asks you the right questions, figures out what's deductible, and explains every answer in plain language.
Restio focuses on income tax — work-related deductions, special expenses, extraordinary burdens, and business expenses for freelancers. VAT (Umsatzsteuer) and trade tax (Gewerbesteuer) are not currently in focus.
Download the app and ask your first 15 questions — completely free. No subscription, no credit card, no commitment. If Restio convinces you, you can keep going. If not, that's it.
Three things: Restio is specialized for German tax law and answers with paragraph, deadline, and number — current for 2026. Restio knows your situation (tax class, state, prior topics) and uses it so you don't have to explain yourself twice. And Restio reaches out on its own when a threshold or deadline is coming. ChatGPT is a good generalist — Restio is a specialist with memory.
Restio stores only what's relevant to your tax situation. You can view, export, or delete anything Restio knows about you at any time. We do not sell your data. For details on purposes, processing, and your rights, see the Privacy Policy.
Yes. Both are built into the app and don't require a request. You can view, export, or delete your profile, history, individual receipts, or your entire account from settings — directly, no waiting.
