In addition to tax advice, I defend you in tax evasion proceedings – with the aim of ending investigations early or even having proceedings discontinued before a trial. Should a trial take place, I will represent you vigorously in court.
Conflicts with the tax office can quickly escalate into criminal proceedings. I will defend you in:
Tax evasion & attempted tax evasion
Withholding social security contributions
Suspicion of money laundering, fraud or embezzlement in a tax context
My goal: To achieve an early dismissal of the proceedings or to consistently enforce your interests in court.

Tax Criminal Defense - Mainz
Tax evasion investigations under Sections 370 et seq. of the German Fiscal Code (AO) are steadily increasing – not because more people are evading taxes, but because the tax authorities are scrutinizing more closely, are better networked, and are investigating more quickly. Anyone participating in economic activity can unexpectedly find themselves targeted by tax investigators. The key to successful tax evasion defense lies in tax law itself: The additional taxes assessed during a tax audit or investigation are often contestable. If these can be reduced, the basis for criminal sanctions automatically diminishes. This is precisely where we come in. As a specialist lawyer for tax law with additional qualifications in white-collar crime (LL.M.), I combine both sides: tax-related argumentation and criminal procedural defense. Our goal is to have the proceedings discontinued during the investigation phase – even before charges are filed. In doing so, we also keep potential collateral consequences in mind: professional disciplinary action, business prohibition, firearms licenses, or immigration implications. Discretion is a given. Swift action is crucial.
FAQ – Frequently Asked Questions for your tax lawyer in Mainz
1. How much does a tax lawyer cost in Mainz?
The costs depend on the scope and complexity of the mandate. In many cases, I work on the basis of a fee agreement, which will be explained to you transparently in advance.
2. Do you also accept cases outside of Mainz?
Yes – I represent clients nationwide, with a focus on Rhineland-Palatinate, Hesse and the Rhine-Main area.
3. Is it worth filing a voluntary disclosure in cases of tax evasion?
A voluntary disclosure can lead to immunity from prosecution if it is complete and submitted on time. I will review your situation and handle the entire process securely.
4. Can you also represent me during a tax audit?
Yes – I accompany tax audits from the beginning, check the legality of the measures and defend against unjustified tax demands.
Defense against tax evasion - Mainz
Steuerhinterziehung liegt vor, wenn jemand gegenüber dem Finanzamt unrichtige oder unvollständige Angaben macht – oder steuerlich erhebliche Tatsachen verschweigt – und dadurch Steuern verkürzt. Der Vorwurf wiegt schwer: Es drohen Geldstrafe oder Freiheitsstrafe bis zu fünf Jahren, in besonders schweren Fällen bis zu zehn Jahren. Entscheidend ist jedoch die Abgrenzung: Wurde vorsätzlich oder nur fahrlässig gehandelt? Bei leichtfertiger Steuerverkürzung (§ 378 AO) handelt es sich lediglich um eine Ordnungswidrigkeit – sanktioniert mit einem Bußgeld, aber ohne Eintrag ins Bundeszentralregister. Sie bleiben nicht vorbestraft. Diese Unterscheidung kann über Ihre berufliche und persönliche Zukunft entscheiden. Als Anwalt für Steuerrecht mit LL.M. im Wirtschaftsstrafrecht prüfe ich, ob die Voraussetzungen einer Steuerhinterziehung überhaupt erfüllt sind – und wo Verteidigungsansätze liegen. Häufig lassen sich bereits im Ermittlungsverfahren Weichen stellen: für eine Einstellung, eine Herabstufung zur Ordnungswidrigkeit oder eine milde Sanktion.Vorwurf erhalten? Jetzt handeln.
Tax dispute with the tax office - Mainz
Almost everyone comes into conflict with the tax office at some point. The crucial thing then is to use the right legal remedies at the right time.
Objection procedure
Doubts about your tax assessment? The objection period is only one month. The procedure is free of charge and often leads to the assessment being revoked or amended – if the grounds for the objection are valid. If the objection is unsuccessful, you can appeal to the tax court.
Suspension of enforcement (AdV)
An objection does not suspend the obligation to pay. Anyone who cannot or does not want to pay the tax until the matter is clarified must file an application for preliminary relief – first with the tax office (§ 361 AO), and if rejected, with the tax court (§ 69 FGO). Prerequisite: serious doubts about the legality of the assessment.
Enforcement defense
The tax office can obtain its own enforcement order. Therefore, it is all the more important to exhaust all legal options – from the statute of limitations for payment (§ 228 AO) to the apportionment of tax liability between spouses (§ 268 AO).
Division between spouses
Jointly assessed, but only one spouse has tax debts? A division application protects the other spouse from enforcement – without losing the advantages of income splitting.
Received your tax assessment? Deadline is approaching.
FAQ – Objection procedures in tax law (Mainz)
1. How long do I have to file an objection against a tax assessment?
You have one month from the date of notification of the tax assessment to file an objection. If this deadline is missed, the assessment usually becomes legally binding.
2. Do I need a lawyer for the appeal process?
Hiring a lawyer is not mandatory, but it significantly increases your chances of success – especially in complex or contentious cases.
3. Will the lawyer also handle communication with the tax office?
Yes. I will handle all correspondence with the tax authorities and ensure that your legal arguments are presented accurately and on time.
4. What happens if the appeal is unsuccessful?
In this case, you have the option of filing a lawsuit with the competent tax court. I will also assist and represent you in this process.
Defense against VAT evasion - Mainz
Die Umsatzsteuer ist die am häufigsten hinterzogene Steuerart – und steht entsprechend im Fokus der Steuerfahndung. Strafbar machen Sie sich, wenn Sie Umsätze nicht deklarieren, zu Unrecht Vorsteuer abziehen oder Steuerbefreiungen in Anspruch nehmen, die Ihnen nicht zustehen. Weniger bekannt: Bereits die Nichtzahlung erklärter Umsatzsteuern kann sanktioniert werden. Bei einfacher Nichtzahlung droht ein Bußgeld bis 50.000 Euro (§ 26b UStG). Wer gewerbsmäßig oder bandenmäßig handelt, riskiert Freiheitsstrafe bis zu fünf Jahren (§ 26c UStG). Ein besonders schwerer Vorwurf betrifft Scheinrechnungen: Hier wird Vorsteuer aus Rechnungen gezogen, denen keine echte Leistung zugrunde liegt. Die Ermittlungsbehörden gehen in solchen Fällen regelmäßig von bandenmäßiger Begehung aus. Als Anwalt für Steuerrecht prüfe ich, ob der Tatvorwurf haltbar ist, welche Verteidigungsansätze bestehen und ob eine Selbstanzeige noch möglich ist. Umsatzsteuer-Nachschau oder Vorladung? Sofort handeln.
FAQ – Häufige Fragen zum Umsatzsteuerkarussell
1. Was ist ein Umsatzsteuerkarussell?
Ein Betrugsmodell, bei dem Warenlieferungen nur vorgetäuscht werden, um unrechtmäßig Vorsteuererstattungen zu erlangen.
2. Ist das immer eine Straftat?
Ja, es handelt sich in der Regel um Steuerhinterziehung nach § 370 AO und oft auch um weitere Delikte wie Geldwäsche.
3. Kann ich belangt werden, wenn ich nichts davon wusste?
Ja – auch unwissentliche Beteiligung kann zu Ermittlungen führen. Der Vorsatz muss aber nachgewiesen werden.
4. Welche Strafen drohen?
Je nach Rolle und Schadenshöhe können Geld- oder Freiheitsstrafen bis zu zehn Jahren verhängt werden.
5. Warum einen Anwalt aus Mainz beauftragen?
Ein spezialisierter Anwalt vor Ort kennt die Vorgehensweisen der regionalen Steuerfahndung und kann schnell eingreifen, um Beschlagnahmen oder Kontosperren zu verhindern.
Self-reporting that grants immunity from prosecution - Mainz
Voluntary disclosure is the only way back to tax compliance – and to immunity from prosecution despite tax evasion. However, it is not a sure thing: formal errors or incomplete information can negate its effect.
Typical triggers:
Investigations into business partners, audits of related entities, inheritances involving undeclared assets, bank account inquiries, data transfers (such as with Airbnb or tax CDs) – or the threat of a former partner reporting you. Many people in these situations believe that the discovery has already occurred. This is often not the case. As long as the tax authorities are not yet aware of the specific offense, voluntary disclosure remains possible. However, swift action is crucial.
The process:
Initial consultation → Estimation of the additional payment → Determination of the exact tax liability → Preparation and submission of the voluntary disclosure → Payment → Review of the amended tax assessments.
Immunity from prosecution is only granted upon full payment. Therefore, we will clarify your liquidity in advance and guide you through the entire process – discreetly and with the necessary expertise in tax law.
Is discovery imminent? Act now – don't wait.
FAQ – Selbstanzeige (Mainz)
1. When is a self-report possible?
Only as long as no investigation or inquiry has been initiated or announced.
2. What must be included in a self-disclosure?
All tax-relevant information from the last ten years must be included completely and correctly.
3. Is self-reporting always exempt from punishment?
No. It only grants immunity from prosecution if it is complete, timely, and truthful.
4. Should I prepare the self-disclosure myself?
No. Even minor formal errors or omissions can invalidate the exemption from punishment – legal counsel is strongly recommended.
Foreign Accounts & Automatic Exchange of Information
Over 100 countries now automatically report account data to the German tax authorities – including Turkey since 2020. Banks, insurance companies, and investment firms transmit information on account holders, balances, interest, dividends, and capital gains.
Turkish accounts in focus
Anyone who is a taxpayer in Germany and maintains an account in Turkey and has not declared the income should expect to receive a letter from the tax office. The authorities will then regularly assume intentional tax evasion – penalties include fines or imprisonment for up to five years, and in serious cases, up to ten years.
Inheritances and gifts from Turkey can also give rise to separate criminal liability for the heirs or recipients if the assets have not been declared.
What to do?
As long as the tax office is unaware of the matter, a voluntary disclosure can provide immunity from prosecution. Important: Act before the data is transmitted – not only when the request arrives.
As a Turkish-speaking specialist lawyer for tax law, I advise you in your native language, examine your tax obligations and, if necessary, prepare an effective voluntary disclosure.

Tax Investigation – Search & Seizure – Mainz
When tax investigators show up at your door at 6 a.m., it's a massive infringement on your rights. Searches of your apartment, house, or office, as well as the seizure of documents and data storage devices, are stressful – and mistakes in the first few minutes can have serious consequences. Common triggers include: information exchanges between tax offices, account inquiries, tax audits, money laundering reports from banks, or reports from third parties. Even initial suspicion is enough for a search. The most important rule: stay calm. You have the right to contact a lawyer before making any statement – use it. Tax evasion cases are rarely won in the first few minutes, but are frequently lost. Is there still time to act? Even after receiving a letter from the tax investigators regarding cash deposits or suspicious transfers (Section 208 of the German Fiscal Code), a voluntary disclosure is often still possible – but only until the formal initiation of criminal proceedings. After that, it's too late.
Tax investigation announced? Call immediately – do not answer.
FAQ – Frequently Asked Questions about Tax Investigations in Mainz
1. What does the tax investigation department in Rhineland-Palatinate do?
It investigates suspected tax evasion or other tax offenses if these fall under the jurisdiction of the state tax authorities.
2. Can the tax investigation unit simply show up at my door?
Yes – provided a judicial search warrant exists, the search may be carried out without prior notice.
3. Do I have to speak to the investigating officers?
No. You are not obliged to provide any information and should speak with a tax lawyer in Mainz before making any statement.
4. What are the officers allowed to search?
Depending on the decision, apartments, business premises, vehicles and electronic devices such as computers or smartphones.
5. Why is a specialist lawyer from Mainz so important?
A local lawyer knows how the regional tax investigation authorities work, can check for procedural errors and implement your defense strategy immediately.
Tax audit – Support & defense – Mainz
Tax audits are known for surprises – rarely pleasant ones. Missing documents, unexplained deposits, cash shortages, or mixed accounts: the tax office exploits every loophole to make estimated assessments. The audit methods are becoming increasingly sophisticated: benchmark comparisons, cash flow statements, net worth calculations, chi-square tests, and recalculations. Those unfamiliar with these methods are largely defenseless. Our approach: the primary goal is to reach an amicable agreement during the audit – before any additional taxes are assessed. If this fails due to the auditor's lack of insight, we represent you in the appeals process and before the tax court. Even in cases where audits have stalled, it's worth taking action: new arguments, a new strategy, a new outcome.
Our services:
Support before, during and after the tax audit
Review and appeal of assessment notices
Objection proceedings and tax court action
Defense against liability notices
As a tax lawyer, I am familiar with the audit methods – and their weaknesses.

FAQ – Tax Audit (Mainz)
1. What is a tax audit?
An external audit conducted by the tax office, usually on-site at the company, to review the tax situation.
2. Do I have to accept a tax audit?
Yes, a properly ordered tax audit is legally permissible and mandatory.
3. How can a lawyer help during a tax audit?
Through strategic preparation, legal support during the audit, and subsequent defense against unjustified findings.
4. Can a tax audit lead to additional tax assessments?
Yes, especially if the tax office identifies discrepancies or formal deficiencies – legal counsel is all the more important.
Tax Court Proceedings - Mainz
The appeal process has failed, the decision on the appeal has been issued – and the tax office is sticking to its position. Now the only remaining option is to appeal to the tax court.
The problem: Massive additional taxes are looming, and the obligation to pay continues – even during the legal proceedings.
The solution: File a lawsuit against the tax assessment and simultaneously apply for a stay of execution (§ 69 FGO). This will prevent you from having to pay before the matter is resolved.
As a tax lawyer, I will thoroughly prepare the facts of your case, develop a legal argument that differs from the tax office's assessment, and represent you before the tax court. If necessary, I will work closely with your tax advisor.
Our services:
Assessment of process risks and prospects of success
Lawsuit before the tax court
Application for a stay of execution (AdV)
Appeal rejected? Now consider filing a lawsuit.
FAQ – Führung von Finanzgerichtsprozessen (Mainz)
1. When is it advisable to file a lawsuit with the tax court?
If an objection has been unsuccessful and the tax assessment remains incorrect, a lawsuit before the tax court can be the last resort to challenge unjustified taxation.
To prevent tax claims.
2. Can payment be suspended during the process?
Yes. By applying for a stay of execution, it is possible to ensure that the assessed taxes do not have to be paid until the court makes a decision.
3. Do I absolutely need a lawyer before the tax court?
For disputes exceeding €5,000 or involving complex tax matters, legal representation is strongly recommended to maximize the chances of success.
Online trading – eBay, Amazon & Co.
Der Handel auf Plattformen boomt – und die Finanzverwaltung schaut genauer hin. Seit 2023 sind eBay, Amazon, Etsy und andere Plattformen durch das Plattformen-Steuertransparenzgesetz (PStTG) verpflichtet, Verkäuferdaten automatisch an das Bundeszentralamt für Steuern zu melden.
Wann wird es kritisch?
Privatverkäufe sind grundsätzlich steuerfrei. Doch wer regelmäßig verkauft, kann als gewerblich eingestuft werden:
-
Mehr als 30 Verkäufe oder über 2.000 Euro Umsatz pro Jahr (Meldepflicht der Plattform)
-
Verkauf von Neuwaren oder gezielten Warengruppen
-
Professionelle Präsentation mit Shopsystem
-
Verkauf im Auftrag Dritter
Auch „Spekulationsgeschäfte" sind steuerpflichtig: Wer Elektronik, Schmuck oder Sammlerstücke innerhalb eines Jahres mit Gewinn weiterverkauft, muss diesen versteuern – ab 600 Euro Gewinn pro Jahr.
Die Steuerfahndung nutzt Software
Mit Programmen wie „Xpider" werden Verkaufsaktivitäten, Bewertungen und Bankdaten automatisiert ausgewertet. Wer auffällt, erhält Post vom Finanzamt – oder Besuch von der Steuerfahndung.
Was tun?
Solange keine Entdeckung vorliegt, kann eine Selbstanzeige Straffreiheit bringen. Diese muss vollständig und korrekt sein – Fehler machen sie unwirksam.
Anfrage vom Finanzamt erhalten? Nicht antworten – zuerst anrufen.
