Sorted 2026: Taxes, EÜR & Freelancer Automation

Launching a freelance or solo business in Germany typically begins with an intimidating 16-page bureaucratic obstacle course: the tax registration questionnaire (Fragebogen zur steuerlichen Erfassung). How does Sorted guide founders from their initial tax number through monthly advance VAT filings to a legally compliant profit return (EÜR) – and how can the platform be automated via APIs?

The German Fiscal Labyrinth: From Registration Anxiety to Tax Numbers

Launching an independent freelance consultancy, software development practice, or creative agency in Germany immediately confronts entrepreneurs with one of Europe's most intricate regulatory gateways: before a business can issue its very first invoice, the fiscal authority (Finanzamt) demands granular projections regarding anticipated revenues, estimated net margins, accounting methodologies, and the binding election between the small business scheme and standard VAT taxation.

For self-employed professionals, the official federal ELSTER portal often proves bewildering: dense terminology derived from the German Income Tax Act (EStG) and Value Added Tax Act (UStG) causes significant confusion. Inadvertently overestimating first-year earnings on the statutory registration form can prompt the tax authority to assess steep quarterly advance tax prepayments, placing severe financial strain on early-stage liquidity.

Berlin-based tax technology platform Sorted (getsorted.de) was engineered specifically to dismantle this administrative friction for freelancers, solopreneurs, and independent creators across Germany.

The Guided Tax Registration Questionnaire

The flagship capability of Sorted within the European software ecosystem is its conversational registration assistant. Rather than navigating static, multi-page PDFs, founders complete an intuitive guided questionnaire:

Following submission, Sorted tracks filing progress and alerts the user as soon as official tax identifiers are assigned. The profile data automatically populates the user's ongoing accounting suite, enabling instant billing readiness.

Ongoing Bookkeeping: Periodic VAT Filings & The Annual EÜR Return

Throughout the active operating year, Sorted automates compliance obligations using the simplified German cash-basis net profit method (EÜR):

Periodic Advance VAT Returns in Under Sixty Seconds

For standard-taxed freelancers, Sorted aggregates all client billing invoices and verified vendor expense receipts. The application calculates the net tax balance (collected sales tax minus reclaimable input VAT) and populates statutory code fields automatically. A simple PIN confirmation files the declaration to the tax office by the 10th-of-the-month statutory deadline.

Statutory Deductions, Home Office Allowances & Hardware Write-Offs

At fiscal year-end, self-employed professionals must balance operating income against operational expenses under § 4 Abs. 3 EStG. Sorted structures deductions according to standard German charts of accounts (SKR03), cleanly categorizing telecommunications, travel expenses, client entertainment, and capital depreciation (AfA).

Particularly advantageous for remote founders and digital contractors are the platform's automated statutory deduction calculators:

• Home Office Flat Rate: Sorted logs qualifying home office working days, applying the statutory flat-rate deduction (up to €1,260 annually or 210 days at €6 per day) directly against taxable income.
• Immediate Digital Asset Depreciation: In accordance with federal fiscal directives regarding the operational life of computer hardware and software, laptops, monitors, and developer tools are expensed at 100% in the year of acquisition.
• Low-Value Assets (GWG): Capital operational tools costing up to €800 net are expensed immediately in the month of purchase without requiring multi-year depreciation schedules.

E-Invoicing Mandates 2026: ZUGFeRD & XRechnung for Solopreneurs

With mandatory European electronic invoicing standards (EN 16931) taking effect across B2B commerce, corporate buyers can legally reject non-structured PDF invoices. Solopreneurs and freelance contractors must possess software capable of creating, validating, and reading electronic documents.

Sorted embeds e-invoicing directly into standard client billing:

• Hybrid ZUGFeRD 2.2: Invoices are formatted as human-readable PDFs containing embedded, machine-readable XML records. Corporate clients can view the invoice visually or ingest it autonomously into enterprise ERP systems.
• Standalone XRechnung: For contracts with German federal ministries, municipal bodies, or public institutions (B2G), Sorted issues standardized XML files complete with buyer reference codes (Leitweg-ID).
• Inbound E-Invoice Processing: Vendor invoices arriving as structured XML attachments are parsed upon upload and pre-assigned to appropriate expense categories.

Open Banking & Automated Transaction Matching

Reconciling bank records manually consumes valuable billable consulting hours. Sorted utilizes European PSD2 open banking bridges to integrate virtually all German financial institutions:

REST API & Programmatic Integration: Connecting Billing Workflows

For software developers, tech contractors, and digital agencies, Sorted offers a RESTful API enabling programmatic synchronization of invoices, expenses, and customer directories from external project management or time tracking platforms.

API Architecture & Sample Request

The API utilizes standard HTTPS endpoints authenticated via Bearer tokens. All communication adheres to clean, structured JSON formats.

Sample cURL request to issue a client invoice programmatically:

curl -X POST https://api.getsorted.de/v1/invoices \
  -H "Authorization: Bearer sec_live_88f91a2b3c4d5e6f" \
  -H "Content-Type: application/json" \
  -d '{
    "recipient": {
      "name": "Acme Innovations GmbH",
      "street": "Technologiepark 14",
      "zip": "10115",
      "city": "Berlin",
      "country": "DE",
      "vat_id": "DE318920194"
    },
    "invoice_date": "2026-10-13",
    "due_days": 14,
    "currency": "EUR",
    "format": "ZUGFERD_2_2",
    "items": [
      {
        "description": "Full-Stack Software Engineering Sprint 42",
        "quantity": 40,
        "unit": "hours",
        "price_net": 110.00,
        "vat_rate": 19
      }
    ]
  }'

Sorted confirms creation with a unique document ID, sequential invoice identifier, and direct link to the finalized ZUGFeRD PDF container:

{
  "id": "inv_74910294",
  "invoice_number": "RE-2026-0048",
  "status": "issued",
  "net_total": 4400.00,

  "format": "ZUGFERD_2_2",
  "created_at": "2026-10-13T10:45:00Z"
}

Hands-On n8n Workflow for Automated Client Invoicing

Integrating Sorted with open-source automation engines like n8n enables fully autonomous month-end billing: upon completion of monthly consulting milestones inside time-tracking tools (such as Toggl or Harvest), n8n triggers invoice creation inside Sorted and transmits the finalized document directly to client accounting desks.

1. 1. Billing Trigger & Monthly Cut-Off

   Scheduled cron interval executing on the 1st of each calendar month or upon approval of consulting milestones.

2. 2. Timesheet Aggregation

   Query billable project hours, rates, and detailed timesheet memos directly via time-tracking APIs.

3. 3. E-Invoice Generation via Sorted

   Invoke POST /v1/invoices on Sorted to generate compliant ZUGFeRD 2.2 / EN 16931 containers.

4. 4. Client Dispatch & Revisions Archive

   Automated transactional email delivery to client finance departments alongside archival inside Google Drive.
