NRW property tax 2026: differentiated B rates, Duisburg’s 24 Feb return to a single B rate, and how to read your 2026 bill

What changed in NRW law

From 1 January 2025, Germany’s reformed property tax (Grundsteuer) applies nationwide. North Rhine‑Westphalia (NRW) follows the federal valuation “Bundesmodell” but added one key option in its own statute: municipalities may set different multipliers (Hebesätze) inside Grundsteuer B—one for residential (valued under the income method) and one for non‑residential (valued under the cost method). NRW also allows a single identical B rate if the city prefers. This option is created by the Nordrhein‑Westfalens Grundsteuerhebesatzgesetz (NWGrStHsG) of 5 July 2024 and applies from 1 January 2025. If a city introduces Grundsteuer C for build‑ready land, that C rate must be higher than both B rates. ([recht.nrw.de](https://www.recht.nrw.de/lmi/owa/br_bes_text?anw_nr=2&aufgehoben=N&bes_id=53629&keyword=gesetz&utm_source=openai))

The NWGrStHsG also introduced an investor‑relevant safeguard: where the statutory Grundsteuerwert significantly overshoots market value, the lower “gemeiner Wert” must be used if you prove at least a 40% deviation. This can matter for unusual assets or recent value drops. The rule applies to NRW assessments from 1 January 2025. Ask a tax adviser (Steuerberater) before relying on this route. ([recht.nrw.de](https://recht.nrw.de/system/files/pdf/state-law-and-regulations/2024/08/09/b1d91b/2024-08-10-gesetz-ueber-die-einfuehrung-einer-opti.pdf))

Under federal law, calculation steps are: Grundsteuerwert × Steuermesszahl = Grundsteuermessbetrag, then × municipal Hebesatz = annual tax. For the reform, the federal Steuermesszahlen were cut roughly ten‑fold and now differ slightly by use (0.031% for residential, 0.034% for non‑residential). Municipalities set Hebesätze autonomously.

NRW is not alone in tweaking B rates, but it is distinctive in letting cities split B by use. In 2025, industry groups estimated that nearly 30% of NRW municipalities used split B rates, which raised competitiveness concerns for businesses. Not all cities adopted the split.

Duisburg: back to a single B rate from 24 February 2026

Duisburg first adopted differentiated B rates for 2025. After lawsuits and revenue shortfalls, the city council decided on 24 February 2026 to switch back to a single Grundsteuer B multiplier for the 2026 tax year. The unified B rate is 1,169%. The city cites two drivers: legal risk (first‑instance courts in Gelsenkirchen and Düsseldorf struck down Bescheide based on split B rates, appeals pending) and a roughly €11.5 m 2025 shortfall versus the state’s revenue‑neutral guidance. Residential B bills rise; non‑residential fall, relative to 2025. ([duisburg.de](https://www.duisburg.de/vv/produkte/pro_du/dez_i/21/grundsteuer_639782_639789_639792_639795_639798_639801))

Duisburg’s own note warns that differentiated B rates could be declared partly void, exposing the budget to up to €140 m per year in risk. Other materials from the NRW Association of Cities also flagged equality‑law concerns and recommended a single B rate to minimise litigation risk. If courts ultimately uphold split B rates, Duisburg may re‑introduce them in future years. ([duisburg.de](https://www.duisburg.de/vv/produkte/pro_du/dez_i/21/grundsteuer_639782_639789_639792_639795_639798_639801))

Takeaway for buyers and landlords: 2026 B bills in Duisburg use one rate for all B properties. In other NRW cities, check the 2026 Satzung or city tax page to see whether your municipality kept split B rates or moved to a single rate.

How to read your 2026 Grundsteuer bill (Bescheid)

Your annual municipal Bescheid multiplies the Grundsteuermessbetrag (from the tax office) by the city’s Hebesatz. Duisburg’s insert for 2026 explains the line‑items clearly: Grundsteuer = Grundsteuermessbetrag × Hebesatz, and the Messbetrag itself equals Grundsteuerwert × Steuermesszahl (§ 15 GrStG). The notice also states that payments are still due even if you object—a legal remedy does not suspend payment. ([duisburg.de](https://www.duisburg.de/vv/medien/dez_i/21/Beilageblatt-Grundsteuerbescheid.pdf))

What to check line by line: - Property type. Residential vs non‑residential drives the federal Steuermesszahl and, in some cities, the B rate. Mixed‑use classification hinges on floor‑area shares; “mixed‑use” typically means 20–80% non‑residential area, per federal guidance to the Valuation Act. If your building’s use mix is misstated, challenge the Finanzamt’s value notices, not only the city bill. ([grsth.bundesfinanzministerium.de](https://grsth.bundesfinanzministerium.de/grsth/2022-2025/A-BewG-GrStG-AE/BewG/Zweiter-Teil-Siebenter-Abschnitt/C-Grundvermoegen/III-Bebaute-Grundstuecke/Paragraf-249/inhalt.html?utm_source=openai)) - Hebesatz used. In Duisburg, 2026 uses a single B rate of 1,169%. In other NRW cities, check whether split B rates apply. NRW’s 2025 median B rate was around 664%, but each city sets its own rate and 2026 values may differ. Always use your city’s 2026 figure. ([duisburg.de](https://www.duisburg.de/vv/produkte/pro_du/dez_i/21/grundsteuer_639782_639789_639792_639795_639798_639801)) - Totals and due dates. By federal law, quarterly instalments fall due on 15 February, 15 May, 15 August and 15 November; smaller annual amounts can be due on 15 February or 15 August. Many Bescheide also show next‑year due dates if unchanged. ([ao.bundesfinanzministerium.de](https://ao.bundesfinanzministerium.de/grsth/2022-2025/A-BewG-GrStG-AE/GrStG-AE/Abschnitt-III-Festsetzung-und-Entrichtung-der-Grundsteuer/Paragraf-28/paragraf-28.html?utm_source=openai))

If you filed Einspruchs against the Finanzamt’s value or Messbetrag notices, the municipality will later amend your bill if those upstream notices change. You must still pay the municipal bill on time unless you have formal suspension. ([duisburg.de](https://www.duisburg.de/vv/medien/dez_i/21/Beilageblatt-Grundsteuerbescheid.pdf))

Objections: which notice, which authority, which deadline

Three different letters can exist for one property—each with its own remedy and deadline: - Grundsteuerwert notice (Finanzamt). If you dispute valuation or use classification, file an Einspruch with the Finanzamt within one month of notification (§ 355 AO). If the legal remedy instruction is missing or wrong, you generally have up to one year (§ 356 AO). ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/ao_1977/__355.html?utm_source=openai)) - Grundsteuermessbetrag notice (Finanzamt). Same remedy and deadlines as above; challenges here change the municipal bill automatically. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/ao_1977/__355.html?utm_source=openai)) - Municipal Grundsteuerbescheid (city). If you dispute the city’s Hebesatz application or arithmetic, file a Widerspruch within one month of notification (§ 70 VwGO). In NRW, a Widerspruch is required before suing for most communal charges, including Grundsteuer (JustG NRW § 110; KAG NRW). If the legal remedy instruction is missing or wrong, the Widerspruch period extends to one year (§ 58 VwGO). ([gesetze-im-internet.juris.de](https://www.gesetze-im-internet.juris.de/vwgo/__70.html?utm_source=openai))

Pay attention: filing the “wrong” remedy usually fails. For example, a Widerspruch against the city Bescheid will not fix an error in the Finanzamt’s Grundsteuerwert; you must attack the Finanzamt notice. Duisburg’s 2026 insert spells this out. Also, payment is still due while remedies are pending unless you obtain a formal suspension. Consult a Steuerberater or a German tax lawyer (Fachanwalt für Steuerrecht) for case‑specific steps.
