Retail Activity Details (Modules)
📊 Physical Indicator Breakdown
In Spain, the Objective Estimation Regime (commonly known as Módulos or Flat-Rate Tax) is a voluntary tax system under IRPF and VAT designed to simplify tax management for small business owners, sole proprietors, and retailers. Unlike direct estimation (where you pay tax on your real net profits), the modules system estimates a legally defined net yield based on physical variables of your business (such as store size, electrical capacity, or number of employees). If your business earns a high revenue with low overheads, this system can be highly profitable, as your tax stays flat regardless of your real profits.
🔍 Exclusion Thresholds for Módulos
Not all sole proprietors can use this special regime. The Personal Income Tax Act establishes strict turnover limits to qualify:
- Global Revenue Limit: Total gross invoicing across all business activities must not exceed €250,000 annually.
- B2B Invoicing Limit: Invoicing to corporate clients or other freelancers must not exceed €125,000 per year.
- Purchases Limit: The total value of purchases of merchandise and external services in the preceding year must not exceed €250,000 annually.
📝 Worked examples
Example 1: Small neighborhood café (Hospitality modules)
Profile: A local bar in Madrid run by its owner full-time (1.00 UT) and one part-time employee (0.50 UT). The local has a surface of 80 m² and contracted power of 10 kW.
- Personal units (1.50 UT): €6,750.00
- Local surface area (80 m²): €4,800.00
- Contracted power (10 kW): €1,200.00
The café pays taxes based on a net yield of €12,750.00 a year, regardless of whether its real card machine transactions show €80,000 or €120,000 in cash.
Example 2: Small boutique fashion store (Retail modules)
Profile: Retail clothing shop managed solely by its owner (1.00 UT). Local size is 60 m² and power is 8 kW.
- Personal units (1.00 UT): €3,500.00
- Local surface area (60 m²): €2,400.00
- Contracted power (8 kW): €640.00
Example 3: Small hairdresser salon with no staff
Profile: Individual beauty salon run by a sole stylist (1.00 UT) in a small 30 m² studio with 5 kW power.
- Personal units (1.00 UT): €3,000.00
- Local surface area (30 m²): €900.00
- Contracted power (5 kW): €250.00
⚠️ Common mistakes
-
Failing to maintain purchase and sales books: Although your tax is not calculated based on actual invoices, you must legally archive all invoices and receipts. This is necessary to prove you remain below the €250,000 purchases and global revenue limits.
-
Registering under modules for excluded activities: Only activities listed in the annual Ministerial Modules Order (mostly hospitality, small retail shops, vehicle workshops, and transport services) are eligible. Intellectual services like IT consulting or programming are completely excluded.
-
Double counting staff during sick leave: If a staff member is on sick leave or maternity leave and you hire a temporary substitute, do not count both. You should only count the actual hours worked by the replacement, deducting the sick employee’s hours.
-
Forgetting to submit Form 131 quarterly: Unlike professional freelancers who are exempt from quarterly prepayments if 70% of their invoices have withholdings, modules sole proprietors are always required to file Form 131 and pay their quarterly share (usually 4%).
❓ Frequently Asked Questions (FAQ)
It is the annual taxable base estimated by law for your business. Under Spain's contribution system, your monthly RETA freelance quota is calculated using this estimated yield, placing you in the corresponding income bracket.
Módulos is highly profitable if your business has high revenues and healthy profit margins, since your taxable income is capped. However, if your business has low earnings or is running at a loss, you must still pay the same flat tax, making direct estimation a better choice.
Form 131 is filed quarterly in the same periods as Form 130: between the **1st and 20th of April, July, and October**, and between the **1st and 30th of January** of the following year.
VAT is declared under the **Special Simplified VAT Regime**, where VAT charged and paid is also estimated using specific indices per activity code, reported quarterly on a simplified **Form 303** return.
No. The election to leave modules must be submitted during the month of **December** to take effect in the next year, or by filing your first quarterly return under Form 130 in April, which binds you to direct estimation for at least 3 years.
One Personal Unit (UT) represents the work of one full-time person over a year (1,800 hours/year). An employee contracted for 20 hours a week will count as 0.50 UT under the modules system.
No. Under the **incompatibility of regimes** principle, if you file one activity under direct estimation, all your other business activities must also be filed under direct estimation, excluding you from modules.
No. Capital or operating grants received by your business do not alter the calculation of your net yield under physical modules. They must, however, be reported on your annual personal IRPF return as extraordinary income.
