Nebenkosten-Check

Your German utility bill (Nebenkostenabrechnung) arrives — and all you understand is the amount you owe. Nebenkosten-Check is the app for tenants in Germany: understand every line, check the bill yourself, and keep your deadlines. Built for German rental law, fully in English. UNDERSTAND: THE COMPLETE COST CATALOG • Every German operating-cost type (§ 2 BetrKV) in plain language: What is this line? May it be charged to tenants at all? • Plus the classics that show up anyway: administration costs, repairs, bank fees, vacancy costs … • A typical pitfall for every cost type — from full-service elevator contracts to the cable-TV rule since July 2024 CHECK IT YOURSELF: FORMAL CHECK & TRAFFIC LIGHT • Free formal check: billing period (max. 12 months), the landlord's 12-month billing deadline, advance-payment comparison — calculated to the day • Benchmark traffic light (Pro): every line in €/m²/month against nationwide German averages — green, yellow, or "worth a closer look" • Chargeability check (Pro): spots the classic non-chargeable items instantly • Scan or PDF import pre-fills your cost lines — recognition runs entirely on device KEEP YOUR DEADLINES • Objection-period countdown: 12 months from receipt (§ 556 German Civil Code) — after that, objections are usually excluded • Reminders 90, 30 and 7 days before the deadline, with a discreet text • Bill arrived late? The app does the math and explains neutrally what that means THE TAX BONUS MOST TENANTS NEVER CLAIM (Pro) • Your bill contains household-related and tradesman services (§ 35a German Income Tax Act): caretaker, cleaning, winter service, garden care, chimney sweep, maintenance • Nebenkosten-Check sums them up for your German tax return — only stated amounts, never estimates • Check report as PDF: for your landlord, the tenants' association, or your tax records PRIVATE BY DESIGN • No account, no cloud, no upload, no tracking — "Data Not Collected" • Your housing and cost data stays on your iPhone Nebenkosten-Check Pro (subscription) unlocks the full check (traffic light + chargeability), the §35a tax extract, the check-report PDF and multiple bills (apartments/years). Free 7-day trial on the yearly plan. Always free: 1 bill, the formal check, the deadline reminder and the complete explainer catalog. Important: Nebenkosten-Check provides general information and calculation aids for checking your own bill — not legal or tax advice for individual cases. For disputes, contact a local tenants' association (Mieterverein) or a lawyer for German rental law. Benchmarks: German Tenants' Association operating-costs index (billing year 2024).
