Three invoices from three years together determine the classification, yet each is looked at on its own.

The invoices arrive one at a time, months apart, often from different trades. With each one, the question of maintenance expense or construction cost comes up afresh, and whoever answers it has to look into the property's purchase contract and the measures booked in previous years. At year end, the same ground is covered a second time for Schedule V of the tax return.

3years in viewFor the test under § 6(1) no. 1a EStG, the three years after acquisition count together.

4borderline casesFor bathroom, windows, heating and roof, the classification does not follow from the invoice text alone.

40minutes per borderline casePurchase contract, prior-year measures and line item text are opened individually for each one.

Proposal, reasoning and legal basis are compiled for all four borderline cases before the tax specialist even opens the invoice: 50% less review effort.

The 50% reduction in review effort is this agent's headline figure. Invoice count, borderline cases and the forty minutes represent a typical year for one property at a tax firm; they are not measured values.

Three steps through the process.

The expense type is settled only when the tax specialist signs off; the agent proposes it for each invoice line and sets out the reasoning and reference alongside.

Assign the invoice lines to the measure

The agent breaks the invoice down into line items and assigns them to the measure carried out on the property. It separates pure repairs from items that raise the building's standard.

Invoice HW-2026-0338, 14 line items, 3 of them raising the standard

Compare the three-year total with the threshold

The agent adds up the net expenses of the three years since acquisition and compares them with the threshold derived from the building share. It states the headroom to the threshold in euros.

Property Bergstrasse 14: 61,300 euros accumulated, 8,900 euros of headroom

Present the classification with reasoning

For each line item, the agent files the proposed expense type, the reasoning and the legal provision relied on. The tax specialist signs off the classification.

What the agent does not do.

It does not determine the expense type.

It proposes it for each line item and names the legal basis. The tax specialist signs off the classification.

It does not split the purchase price between land and building.

It works with the building share recorded in fixed assets. If that split is wrong, the headroom shown is wrong too, and the tax specialist makes the correction.

It does not count invoices sitting in the landlord's folder.

Only what is recorded in the property file goes into the three-year total. The gutter the landlord paid for in cash and never submitted is missing from the 61,300 euros until it is recorded.

The questions that come up before the first meeting.

How quickly is the Maintenance Expense Classification Agent ready to use?

A pilot typically runs on your own data within 4 to 6 weeks. The agent connects to your existing systems rather than running as a separate, parallel environment.

Where is the data processed?

EU cloud, private cloud or on-premises. Processing is GDPR-compliant and models are never trained on your data. Details in the Trust Center.

Where does the figure “50% less review effort” come from?

It is based on experience from comparable projects and process benchmarks, not a commitment. We establish the realistic effect for your organisation in the assessment before the pilot.
