Why You Need a Charging Cost App in 2026
Since January 1, 2026, new rules apply to the tax deduction of charging costs in Germany: The old monthly flat rate has been abolished, and only actually documented charging sessions are deductible. The new electricity price allowance of €0.34/kWh for home charging requires seamless, GoBD-compliant recording of every single charging session.
Which app can help? We compared the most popular EV apps — focusing on what actually matters for taxes.
The Apps at a Glance
EEVEE
EEVEE is an international charging app with community features. The app offers a charger finder, route planner, and trip log. EEVEE targets a broad audience across Europe.
Strengths: Large community, route planner, international charger finder.
Tax limitations: As of our research (March 2026), EEVEE does not offer GoBD-compliant recording, DATEV export, or specific support for the German home charging allowance.
EnBW mobility+
EnBW mobility+ is primarily a charging app for the EnBW charging network and roaming partners. The app enables starting and paying for charging sessions at public stations.
Strengths: One of the largest charging networks in Germany, easy payment, good coverage.
Tax limitations: EnBW mobility+ only documents charging sessions at public stations in its own network. Home charging is not recorded as of our research. No GoBD-compliant export, no DATEV format.
Ladefuchs / Chargeprice
Ladefuchs (and the similar Chargeprice) are price comparison apps for public charging. They help find the cheapest charging rate at a station.
Strengths: Transparent price comparisons, wide tariff selection, quick overview.
Tax limitations: Pure price comparison apps without documentation features. No recording of charging sessions, no export, no GoBD compliance.
Charge Repay
Charge Repay is a B2B solution specializing in fleet management and reimbursement of charging costs for companies. The solution includes hardware (wallbox meters) and software.
Strengths: Professional fleet solution, partially GoBD-compliant, billing system for employers.
Limitations for individuals: As of our research, oriented toward B2B/fleets, not available as a consumer app. No individual license, no app store availability.

What None of These Apps Do
The result is clear: None of the alternatives were built for tax documentation of charging costs in Germany. They solve different problems — finding chargers, comparing prices, planning routes, managing fleets.
The gap: As of our research, there is no other consumer app that:
- Offers GoBD-compliant recording
- Has a DATEV export for tax advisors
- Automatically calculates the €0.34/kWh allowance
- Provides wallbox integration for automatic home charging recording
- Works 100% offline without cloud dependency
Who Is LadeKosten For?
LadeKosten was built specifically for this gap. The app targets:
- Freelancers and self-employed professionals with EVs
- Company car drivers who charge at home
- Employees with reimbursement claims from their employer
- Everyone who wants to maximize their charging cost tax deductions
The Right Combination
The good news: You don't have to choose just one app. LadeKosten complements the other apps perfectly:
- Ladefuchs for price comparison at the station
- EnBW mobility+ for charging and paying on the go
- LadeKosten for tax documentation of all charging sessions
What to Look for in a Charging Cost App
Not every EV app is automatically a good charging cost app. If you want to deduct your charging costs from taxes, you need to evaluate apps against very specific criteria. Here are the seven most important factors a charging cost app should meet in 2026:
GoBD Compliance
The GoBD (Principles for the Proper Management and Storage of Books, Records, and Documents in Electronic Form and for Data Access) is the central standard for digital records in Germany. A charging cost app must ensure that entries are immutable, traceable, and complete. This means every charging session is recorded with a timestamp, quantity (kWh), location, and cost — and cannot be manipulated after the fact. Without GoBD compliance, you risk having the tax office reject your entire documentation.
DATEV Export
Your tax advisor works with DATEV — the standard accounting system in Germany. An app that offers DATEV export saves significant time for both you and your tax advisor. Instead of manually sorting receipts, the advisor imports your charging costs directly into their software. This reduces errors and speeds up the tax return.
Wallbox Integration
If you charge at home with a wallbox, you need automated recording. Manual entry after every charging session is error-prone and easily forgotten. A good app connects to common wallbox models and captures the data automatically — including kWh quantity, charging duration, and timestamp.
Offline Capability
Not every garage has Wi-Fi, and not every charging point has mobile reception. An app that only works online creates gaps in your documentation. Offline capability ensures that every charging session is recorded immediately — even without an internet connection. Synchronization happens automatically later.
Data Privacy: Local vs. Cloud
An often underestimated criterion: Where are your charging data stored? Cloud-based solutions send your location data, charging times, and consumption patterns to external servers. Local storage — directly on your device — gives you full control over your data. Especially for tax-relevant documents, this is an important consideration.
Usability
The best app is worthless if you stop using it after two weeks. Simple operation, clear overviews, and a quick recording process are essential. Ideally, the app captures a charging session with just a few taps — or documents it fully automatically via wallbox integration.
Value for Money
Free apps sound tempting but typically offer no tax documentation. The key question is: What does the app cost compared to what you save on taxes? Even with just one charging session per week, the deductible amounts quickly add up to several hundred euros per year. An app costing €7.99 per year that secures €500 in tax savings offers excellent value for money.
Detailed Comparison: Features at a Glance
To make the differences between apps visible at a glance, we compiled the most important criteria in an extended comparison table:
| App | GoBD | DATEV | Wallbox | Offline | Data Privacy | Price |
|---|---|---|---|---|---|---|
| LadeKosten | ✅ Full | ✅ Yes | ✅ Yes | ✅ Yes | Local on device | from €7.99/year |
| EEVEE | ❌ No | ❌ No | ❌ No | ❌ No | Cloud | Free |
| EnBW mobility+ | ❌ No | ❌ No | ❌ No | ❌ No | Cloud | Free |
| Ladefuchs | ❌ No | ❌ No | ❌ No | ❌ No | Cloud | Free |
| Charge Repay | ✅ (B2B) | Partial | ✅ (own HW) | ❌ No | Cloud (B2B) | On request |
Note: The table reflects the status at the time of our research (March 2026). Manufacturers may add features at any time.
Particularly notable: LadeKosten is the only consumer app that delivers a clear Yes across all tax-relevant categories — GoBD, DATEV, Wallbox, Offline. At the same time, the app remains one of the most affordable solutions at €7.99 per year, since the free alternatives simply offer no tax documentation.
Why GoBD Compliance Is Non-Negotiable in 2026
With the elimination of the old monthly flat rate on January 1, 2026, the tax landscape for EV owners has fundamentally changed. The new electricity price allowance of €0.34/kWh sounds simple at first — but it comes with a critical catch: you must document every single charging session to be eligible for the allowance.
The BMF letter (Federal Ministry of Finance) makes clear that documentation must meet GoBD requirements. In concrete terms, this means:
- Immutability: Once recorded, charging sessions may not be subsequently altered or deleted.
- Traceability: Every entry must contain a timestamp, the charged quantity in kWh, the charging location, and the calculated costs.
- Completeness: Gaps in documentation can lead the tax office to reject the entire deduction — not just the missing charging session.
- Machine readability: The data must be in a format that can be processed by machines — handwritten notes or screenshots are not sufficient.
Anyone still working with an Excel spreadsheet in 2026 is operating in a gray area. Excel files can be modified retroactively and therefore do not meet the GoBD requirement of immutability. In the worst case, you lose not only one year's tax savings but also risk an audit of previous assessment years.
A GoBD-compliant app like LadeKosten solves this problem automatically: every charging session is stored immutably, tagged with all required data, and can be exported as an audit-proof file for your tax advisor.
Which App Is Right for Which User
Not every EV owner has the same requirements. Here is our recommendation by user type:
Freelancers and Self-Employed → LadeKosten
For the self-employed, comprehensive documentation of business expenses is mandatory. Charging costs for your business EV are fully deductible — provided the documentation is in order. LadeKosten delivers GoBD-compliant records, DATEV export, and automatic allowance calculation. This saves not only taxes but also the time otherwise spent preparing receipts.
Company Car Drivers Charging at Home → LadeKosten
If you charge your company car at home, you are entitled to reimbursement of electricity costs from your employer — or you can claim the costs on your tax return. In both cases, you need clean documentation. LadeKosten records home charging automatically via wallbox integration and generates the proof that your employer or the tax office will accept.
Fleet Managers → Depends on Fleet Size
For small fleets (up to about 10 vehicles), LadeKosten per driver can be a pragmatic solution. For larger fleets, it is worth looking at B2B solutions like Charge Repay, which include centralized billing systems and proprietary hardware. The downside: higher costs, longer implementation time, and often proprietary wallbox hardware required.
Private Individuals Without Tax Needs → A Simple Note Is Enough
If you use your EV purely for private purposes and do not want to deduct charging costs, you do not need a specialized app. A simple note-taking app or no documentation at all is perfectly sufficient. The free apps like Ladefuchs or EnBW mobility+ are good companions for price comparison and charging on the go — these users do not need tax documentation.

Conclusion
If you want to deduct your EV charging costs in 2026, you need more than a charging app or a price comparison tool. Tax documentation — GoBD-compliant, with DATEV export and automatic allowance calculation — is its own task that, as of our research, only LadeKosten covers as a consumer app.
The right app depends on your usage profile: freelancers and company car drivers benefit most from a specialized solution like LadeKosten. Fleet managers should consider B2B solutions above a certain fleet size. And if you use your EV purely privately, you can get by without a tax app — but should be aware of the savings you are leaving on the table.
