A letter from the tax office may provide information, request documents, assess a tax, or trigger a payment deadline or a deadline for filing an objection. First check the type of letter, tax number, period, amount, date of receipt, and deadline. If anything is unclear or the consequences could be significant, professional tax advice is advisable.

Always work from the complete original: document the date of receipt, retain the file reference or tax number, read the explanations and attachments, mark deadlines, and trace any discrepancies. AI can summarize content and highlight review points, but it cannot replace a binding tax assessment or deadline calculation.

What Does the Tax Office Do?

The tax office is responsible for many tax-related tasks. It registers your self-employed activity, issues or manages tax numbers, processes tax returns, reviews information, assesses taxes, and may require advance payments. Income tax, VAT, the trade tax base amount, payroll tax for employees, and tax-relevant supporting documents are particularly important for self-employed people.

  • Registering your self-employed activity for tax purposes
  • Issuing and managing your tax number
  • Processing tax returns and attachments
  • Reviewing VAT advance returns and annual returns
  • Assessing income tax, VAT, and advance payments
  • Questions about supporting documents, turnover, or business expenses
  • Sending tax assessment notices, notifications, and payment demands

Getting Started: Tax Registration and Tax Number

When you start a self-employed activity, you must inform the tax office. To do so, you submit the tax registration questionnaire electronically via ELSTER. It asks for details about your activity, legal form, expected turnover, profit, VAT, the German small-business VAT exemption (Kleinunternehmerregelung), and your bank account. Once the questionnaire has been processed, the tax office will generally issue a tax number for your self-employed activity.

  • Prepare your ELSTER access
  • Complete the tax registration questionnaire
  • Enter the activity, start date, and legal form correctly
  • Estimate expected turnover and profit realistically
  • Make an informed choice between the small-business VAT exemption and standard VAT taxation
  • Enter your bank details and contact information correctly
  • Wait for your tax number, then issue invoices with all required details

Typical Letters from the Tax Office

Tax office letters can have very different meanings. Some letters merely confirm information, while others request additional information or documents. Still others contain a tax assessment, a payment demand, a reminder, or a decision on your application. Therefore, you should first determine what type of letter you are dealing with and whether there is a deadline.

  • Notification of your tax number
  • Question about the tax registration questionnaire
  • Request to submit a tax return
  • Tax assessment notice or advance payment notice
  • Payment demand or payment reminder
  • Request for documentation, business expenses, or turnover
  • Information about the VAT advance return
  • Tax audit order or notice of an upcoming audit
  • Response to an objection, application, or extension request

Understanding a Tax Assessment Notice

A tax assessment notice contains the tax office’s decision about a tax. It shows the basis of taxation used, the tax assessed, whether a further payment or refund is due, and whether advance payments have been adjusted. The amount on the first page is not the only important detail. Also check the explanations, any differences from your tax return, the notice of appeal rights, the payment deadline, and possible additional amounts such as interest or late-filing penalties.

  • Record all mandatory details correctly
  • Keep track of deadlines
  • File documents so they remain traceable
  • Check the type of tax and assessment year
  • Check the tax number and recipient
  • Compare the assessed tax with your expectations
  • Check any refund or additional payment
  • Read the tax office’s explanations
  • Mark any differences from your tax return
  • Check the payment deadline and bank details
  • Check the notice of appeal rights and the objection deadline
  • File the notice digitally and keep it traceable

Tax Office Deadlines: Do Not Rely on Guesswork

Always document tax office deadlines precisely. These include filing deadlines, payment deadlines, objection deadlines, and deadlines for submitting additional documents. For tax assessment notices, the date of notification is important because the objection deadline often depends on it. Under the current notification rules, a written or electronically transmitted administrative act is deemed to have been notified on the fourth day under certain conditions, unless it was received later or not received at all.

  • Record the date of the letter and the date received separately
  • Keep the envelope if the date of receipt could be important
  • Check the filing deadlines for tax returns
  • Do not confuse payment deadlines with objection deadlines
  • Enter deadlines in your calendar or task list immediately
  • Contact a tax advisor or the tax office early if deadlines are unclear
  • Do not wait until the last day to respond

Objecting to a Tax Assessment Notice

If you disagree with a tax assessment notice, you may be able to file an objection. The notice of appeal rights explains how and by when you can respond. Under German tax law, an objection is the usual legal remedy against many tax office notices. Important: do not file an objection solely out of frustration. Prepare it with specific points, supporting documents, and reasons. For larger amounts or complex cases, professional tax advice is advisable.

  • Read the notice of appeal rights
  • Check the objection deadline
  • Mark specific discrepancies
  • Gather supporting documents and evidence
  • Prepare a factual justification
  • Review unresolved payment issues separately
  • If necessary, seek professional advice on a suspension of enforcement
  • Save a copy of the objection and proof of dispatch

VAT, Advance Returns, and Advance Payments

For many self-employed people, VAT is the most frequent form of ongoing contact with the tax office. If the German small-business VAT exemption (Kleinunternehmerregelung) does not apply to you, you must show VAT correctly, check your entitlement to deduct input VAT, and submit VAT advance returns on time. The tax office may also assess income tax advance payments. These payments are not a penalty; they are instalments toward the expected annual tax.

  • Check whether VAT applies or the small-business VAT exemption is available
  • Show VAT correctly on invoices
  • Deduct input VAT from incoming invoices only when entitled to do so
  • Submit VAT advance returns on time
  • Keep track of the payment due date
  • Arrange a SEPA direct debit mandate or make the transfer on time
  • Include income tax advance payments in your cash-flow plan
  • Set aside reserves for tax payments

Documents and Evidence: What the Tax Office Can Review

When the tax office asks questions, it often wants supporting evidence. This may include invoices, receipts, contracts, proof of payment, bank statements, journeys, hospitality expenses, private-use portions, or unclear business expenses. Simply storing documents somewhere is not enough. They must be easy to find, legible, and assigned to the relevant business transaction.

  • Save all outgoing invoices
  • Organize incoming invoices and receipts
  • Link payments to invoices and supporting documents
  • Separate personal and business expenses
  • Add notes to unclear documents
  • Keep contracts and agreements accessible
  • Document official correspondence together with deadlines and responses
  • Keep documents ready for your tax adviser and the tax office

Communication with the Tax Office

Communication with the tax office should be factual, complete, and traceable. Always include the tax number, file reference, or reference to the relevant notice. If documents are missing, responding early is generally better than remaining silent. Phone calls can help, but they do not replace a documented response when deadlines, objections, or important evidence are involved.

  • Always include your tax number or file reference
  • Clearly state the subject and period
  • Attach all requested documents
  • Write factual and concise responses
  • Save phone notes with date and contact person
  • Keep upload confirmations and proof of dispatch
  • Apply for an extension early if necessary
  • Involve a tax adviser in complex matters

Common Mistakes When Dealing with the Tax Office

Many problems with the tax office arise not from bad intentions but from poor organization. Letters remain unattended, deadlines are assessed incorrectly, supporting documents are missing, or tax payments are not planned for. Small businesses do not need a complicated tax apparatus; they need a reliable office process: record, review, file, remind, and respond on time.

  • Submit the tax registration questionnaire too late
  • Fail to store the tax number and file reference properly
  • Leave tax office letters unopened
  • Confuse objection deadline with payment deadline
  • Submit VAT advance returns late
  • Fail to set aside reserves for tax payments
  • Collect documents only as photos or loose PDFs
  • Mix personal and business expenses
  • Fail to document information provided by phone
  • Seek tax advice only when deadlines are almost over

FAQ

Frequently Asked Questions about the Tax Office

When do I need to report to the tax office?

When you start a self-employed activity, you must submit the tax registration questionnaire electronically via ELSTER to the responsible tax office within one month. If the activity is commercial, you must also register the business with the responsible authority.

Where do I get my tax number?

The tax office generally issues the tax number. For a new self-employed activity, you usually receive it after the tax registration questionnaire has been processed.

What is the difference between tax number and tax ID?

The tax ID is a personal identification number for a natural person. The tax number relates to a specific tax matter handled by the tax office, such as your self-employed activity or business.

What should I first check on a tax assessment notice?

Check the type of tax, year, tax number, amount of tax determined, refund or additional payment, explanations, payment deadline, and notice of appeal rights. Highlight any discrepancies from your declaration and clarify them with your tax advisor if necessary.

How long do I have to file an objection?

An objection to a tax assessment notice must generally be filed within one month of notification. The specific deadline is stated in the notice and the notice of appeal rights. If in doubt, have a professional check the deadline.

What happens if I miss a deadline at the tax office?

That depends on the deadline. Possible consequences include late-filing penalties, late-payment penalties, coercive fines, reminders, or the loss of appeal rights. Document tax office deadlines immediately and seek clarification early if a problem arises.

When do I have to submit a VAT advance return?

If you are required to file one, the VAT advance return must generally be submitted electronically by the 10th day after the end of the advance return period. Whether you file monthly, quarterly, or on a different schedule depends on your specific case.

Can I resolve everything with the tax office over the phone?

Phone calls can be helpful, but they should be documented when important matters are involved. Note the date, time, person you spoke with, and outcome. A traceable written record is especially important for deadlines, objections, or evidence.

Can MIRA explain tax office correspondence?

Yes. MIRA can summarize tax office letters in clearer language, highlight deadlines, amounts, tax numbers, and review points, and explain the content in your chosen language. However, MIRA does not replace tax advice or a binding review of an individual case.

Does Motorica replace my tax adviser?

No. Motorica helps organize invoices, supporting documents, payments, deadlines, and records. Tax advice, grounds for objections, binding reviews, and decisions in individual cases remain the responsibility of your tax adviser or the tax office.
