166 
167## Section 9 -- Common Mistakes and Refusals
168 
169**R-ES-F1 -- Capital of €1 without understanding consequences.** "While €1 is the legal minimum since 2022, capitals below €3,000 trigger mandatory profit-reserve rules and potential joint director liability. Always advise on these constraints before proceeding."
170 
171**R-ES-F2 -- Forgetting autónomo societario obligation.** "The administrador of an S.L. must register as autónomo societario and pay social security contributions (~€370/month in 2026). This is a significant ongoing cost that founders frequently overlook."
172 
173**R-ES-F3 -- Not depositing annual accounts.** "Failure to deposit cuentas anuales with the Registro Mercantil results in the company being unable to file new deeds (cierre registral) and potential fines up to €60,000."
174 
175**R-ES-F4 -- NIE not obtained before notary appointment.** "All founders and directors must have a valid NIE before the notary can execute the escritura. This is the most common cause of delay for foreign founders."
176 
177**R-ES-F5 -- Shell company request.** "This skill will not assist in forming a company without genuine economic substance. Spanish anti-money-laundering regulations require identification of beneficial owners and real business activity."

181## Section 10 -- Timeline
182 
183| Step | Duration | Cumulative |
184|---|---|---|
185| Obtain NIE (if foreign founder) | 1--6 weeks | Day 1--42 |
186| Name reservation (certificación negativa) | 1--3 days | Day 2--45 |
187| Draft estatutos and prepare documents | 1--3 days | Day 3--48 |
188| Open bank account and deposit capital | 1--5 days | Day 4--53 |
189| Notary appointment (escritura) | 1 day | Day 5--54 |
190| CIF provisional (AEAT) | 1 day | Day 6--55 |
191| Registro Mercantil registration | 5--15 days | Day 11--70 |
192| Social security registration | 1--3 days | Day 12--73 |
193| **Ready to trade** | | **~2--4 weeks (with NIE already in hand)** |
194 
195The bottleneck for foreign founders is obtaining the NIE, which should be started well in advance.
