Surviving irregular income and slow months, including August

Terms used

• Autónomo — An autónomo is a self-employed person registered with Spain's social security, who pays a monthly contribution.
• IVA — IVA is Spain's value-added tax, which you collect on invoices and pay over quarterly.
• IRPF — IRPF is Spain's personal income tax, paid in advance by freelancers each quarter.
• Cese de actividad — The cese de actividad is a benefit for autónomos who must close their activity involuntarily, not for slow months.
• RETA — RETA is the social security regime for self-employed workers.
• Mutua — A mutua is a mutual insurance body that manages some autónomo benefits, including the cese de actividad.

Key rules

• Reserve: Keep a reserve of 3 to 6 months of expenses, and up to 12 months if your income is very irregular.
• Quota keeps running: Your monthly autónomo contribution is due even in months when you earn nothing.
• Legal payment term: Businesses must pay within 30 days, or up to 60 days if agreed, but real payment often takes longer.
• Late payment: A late payer owes default interest and a fixed 40 euro recovery cost.
• Slow months: Cese de actividad does not pay you for ordinary slow months.

The short answer

Your monthly autónomo contribution and quarterly taxes keep running when your income stops. Build a reserve, invoice early before the quiet periods, and plan your cash flow around when clients actually pay, not when the invoice says they should.

When the slow months hit

August is the slowest month. Many clients and public bodies close or slow down, so work dries up and invoices get approved late. The Christmas period, from about 23 December to 6 January, is also slow.

Work you invoice in July or December often gets paid in September or January. So a busy July can still leave you with an empty bank account in August. This hits hardest if your clients are in Spain. Clients abroad are less affected.

How big your reserve should be

Keep 3 to 6 months of expenses. Count your personal costs and your business costs together. Add the money you will owe in quarterly IVA and IRPF, and your monthly autónomo contribution.

If your income is very irregular, aim for the top of that range or beyond it. Up to 12 months is reasonable.

Build it in good months. Move a fixed share of each payment into a separate account as soon as it arrives. Money set aside for IVA and IRPF is not yours to spend, so keep it apart from the reserve.

Plan around late payers

The legal maximum between businesses is 30 days from delivery. You can agree up to 60 days in the contract. In practice, Spanish companies often pay later. Average payment times are roughly 60 to 70 days, and large firms and public bodies are often slower.

So plan your cash flow on 60 to 90 days, not 30. Then:

• Send invoices for July and December work as early as you can, ideally the day the work is finished.
• Put the payment term in your quote or contract.
• Chase politely when the due date passes.
• Late payment entitles you to statutory default interest, set at the European Central Bank reference rate plus 8 percentage points, and a fixed 40 euro recovery cost. Ask for both in writing if a client keeps you waiting.

Public-sector clients have their own 30-day rules.

Does the unemployment-style benefit help?

Not for slow months. The cese de actividad benefit only covers an involuntary closure of your activity. Examples are serious economic losses, force majeure or loss of a licence. You must be registered in RETA, have paid the cese contribution, have at least 12 months of contributions and be up to date. You must also close the activity and deregister. It lasts between 2 and 24 months depending on how long you contributed.

A separate partial benefit exists for temporary drops in income. Ask the Seguridad Social or your mutua whether you qualify and what the thresholds are.

Do not count on either as a substitute for a reserve. The timeline and FAQ below cover the order of steps and common questions.

Timeline and deadlines

• Build a reserve of 3 to 6 months of expenses: Before your first slow month; build towards up to 12 months if your income is very irregular

• Send invoices for July and December work early: Before clients close for August (slowest month) and from about 23 December to 6 January

• Expect payment on the legal term: 30 days from delivery, or up to 60 days if agreed in writing

• Plan your cash flow for real payment times: Around 60 to 70 days after invoicing is common in practice

• Claim default interest and the 40 euro recovery cost from late payers: Once the legal term has passed without payment

• Check cese de actividad only if you must close your activity: After at least 12 months of continuous contributions; the benefit lasts 2 to 24 months

Frequently asked questions

Does the cese de actividad pay me during slow months?

No, the cese de actividad benefit does not cover ordinary slow months, because it only applies when you close your activity for good for a qualifying cause. Those causes include heavy economic losses, force majeure or loss of a licence. You must be deregistered as an autónomo, have paid the cese contribution and have at least 12 months of contributions, and the benefit lasts 2 to 24 months.

How long do Spanish clients really take to pay an invoice?

Spanish companies often take around 60 to 70 days to pay, even though the legal limit between businesses is 30 days, or up to 60 days if agreed. Large firms and public bodies are often the slowest. If a client pays late, you can claim statutory default interest plus a fixed 40 euro recovery cost.

Will invoices I send in July or December be paid on time?

Often not, because invoices sent in July or December commonly arrive only in September or January. Invoice early in those months and send reminders before the client closes. Clients abroad are less affected by the Spanish August and Christmas slowdowns.
