One classification, three taxes, and no process in the firm that prompts a review.

The landlord reports no change, because he notices none. At the tax firm, it surfaces as a new line in the income schedule, such as a charge for final cleaning. Whoever picks it up gathers the details of the letting and works through the consequences for income tax, trade tax and VAT one by one.

9criteriaLength of stay, turnover of occupants, additional services and advertising together determine the classification.
3taxesIncome tax, trade tax and VAT follow the same classification and are considered separately.
14months' delayThe change goes unnoticed until the annual return is filed, and by then the trade registration is long overdue.

Otherwise a misclassification goes unnoticed for fourteen months. That window is exactly where the 45% fewer misclassifications come from, because both columns are side by side on the day the new line appears.

The 45% fewer misclassifications are this agent's headline figure. The number of criteria, the taxes affected and the delay until the return reflect a typical case for a let property; they are illustrative, not counted.

Three steps through the process.

The agent sets private asset management and commercial business side by side with criteria and tax consequences; the comparison ends without a recommendation.

Collect the characteristics of the letting

The agent collects length of stay, changes of occupant, additional services and the way the property is advertised from tenancy agreements and statements. Each criterion is given its source reference.

Property Seeweg 7: 9 criteria collected, 26 changes of occupant in the year

Set both classifications side by side

The agent lays the criteria out in two columns: private asset management and commercial business. It marks which way each criterion points and which remain open.

List the tax consequences per column

For both columns, the agent lists the consequences for income tax, trade tax and VAT. The tax specialist and the legal adviser take it from there.

What the agent does not do.

It does not recommend either classification.

It sets both side by side with criteria and consequences. The tax specialist and the legal adviser decide together which one applies.

It does not register a trade.

It records the month in which the criteria changed. The landlord files the registration with the municipality himself.

It does not say whether 26 changes of occupant a year is a lot.

It states the figure for the property at Seeweg 7 and the related criteria: short stays and frequent turnover. *At what point that becomes a commercial business is for the tax specialist and the legal adviser to weigh.*

The questions that come up before the first meeting.

How quickly is the Rental 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 “45% fewer misclassifications” 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.
