How this service works
Simulateur IFI, PER, IR et retraite (32 régimes). Logiciel CGP : bilan patrimonial, déclaration 2042, LMNP. Chiffres sourcés Légifrance et BOFiP. 14 jours d'essai.
Output
Returns a JSON object containing the PER deduction ceiling in EUR (value + unit + label), the fiscal vintage (millesime_fiscal), the confidence level of the result, the list of primary legal sources (CGI articles from Légifrance/BOFiP), and the year of income considered. The result is clearly flagged as an informational calculation, not personalized financial advice.
Example use cases
Employee annual PER tax planning
“I earn 55,000 EUR as a salaried employee and want to know the maximum amount I can contribute to my PER and deduct from my taxable income this year — can you calculate my PER plafond?”
Self-employed TNS retirement deduction
“I'm a TNS consultant with a BNC income of 120,000 EUR. What is my PER deduction ceiling under article 154 bis for the current fiscal year?”
Wealth manager client report
“I'm preparing a tax optimization review for a client who is a salaried employee earning 40,000 EUR net. What is their maximum PER deductible contribution ceiling, and what legal sources back the calculation?”
Technical details
Endpoint
POSThttps://app.qotien.fr/api/fiscal/v1/calc/per_plafondWhen to prefer
Use this endpoint when you need a legally-sourced, regulation-backed French PER tax-deduction ceiling calculation for either salaried employees (CGI art. 163 quatervicies) or TNS/BNC self-employed professionals (CGI art. 154 bis). Prefer this over generic tax calculators when traceability to official French legal texts (Légifrance, BOFiP) is required, or when building CGP (wealth management) tools that need auditable fiscal simulations.
Side effects
- Negative or non-numeric revenu_professionnel returns validation error
- Missing required fields return 400-level error with error field in place of result
- Confidence may be 'estime' or 'partiel' for edge-case income profiles
- Result may be 0 EUR if income is below applicable threshold
- API returns ok:false with an error descriptor if calculation is not possible
