Zweitwohnung
Second-home tax records helper
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Zweitwohnung helps you keep clear, organized records for a work-related second household in Germany.
Record calendar and absence days, arrivals, departures, trips home and return trips, provided meals, accommodation, furnishings, moving costs, and other expenses. Select multiple calendar days at once to record full-day absences. Invoices and receipts can be attached directly to an expense from Photos or Files.
Manage multiple three-month meal allowance periods and quickly switch between them in the calendar. Each period can have its own main home, second home, work location, and distance. You can also document a new period resulting from a different work location or a sufficiently long interruption.
The annual overview creates a clear, non-binding estimate based on your entries. It can account for meal allowance rates, meal reductions, period-specific distances, year-based mileage rules, and your saved accommodation cap. Built-in checks highlight missing information and possible duplicate entries.
Preview your annual PDF report before exporting it and choose which meal allowance periods to include. Attached image and PDF receipts can be incorporated into the report. A CSV preview is also available for reviewing raw data. PDF and CSV files can then be shared with Numbers, Excel, or other apps through the iOS share sheet.
Your records and attachments are stored on your device. There is no Mathricks account, no Mathricks servers, no analytics, and no tracking. If you want it, the app also keeps a backup in your own iCloud so your records survive a lost device. The backup is off by default, you decide whether to turn it on, and you can switch it off and delete it from iCloud at any time in Settings. It contains your days, expenses, receipts, and generated reports, and it stays in your iCloud account only.
Zweitwohnung supports the private preparation of your tax records. Its results are non-binding estimates and do not constitute tax advice. Personal eligibility and tax treatment should be reviewed before filing.

Thank you for using Zweitwohnung! We’ve continued improving the app to make your records clearer and preparing your second-household tax documents even easier.
New in version 2.1:
• The tax file now shows the relevant Anlage N figures, including full absence days, arrival and departure days, and tax-free employer reimbursements.
• The first trip to the second home and the final trip back to the main home can now be recorded separately.
• Improved travel-cost review: public transport tickets are compared with the mileage allowance annually, while flights, ferries and car journeys follow their respective rules.
• A new eligibility evidence checklist lets you record statuses, notes and supporting documents.
• Optional proof of travel can be attached directly to calendar days.
• Parking costs are considered separately from the monthly accommodation limit.
• Improved adaptive layout: on larger displays, the calendar and day details appear clearly side by side.
