FAQs and articles about taxes

General

When does it make sense to switch from self-employed to an SL?

As a rough reference (not a legal figure), it usually starts to pay off between €40,000 and €60,000 in annual profit, or sooner if you want to limit your personal liability. More information in the article.

What if I don’t invoice anything in a quarter?

We file a zero return. It’s included in your fee. If you know you’ll have a quiet stretch, we can offer a reduced fee.

Why does the price of an accounting firm vary so much between businesses?

It depends on your tax regime, how many invoices you issue, whether you have employees, and whether you want reporting on top of tax filing.

When does Verifactu actually become mandatory?

1 January 2027 for companies and 1 July 2027 for freelancers, per Royal Decree-Law 15/2025. Not July 2026, which is the outdated date still circulating. (Reviewed: 27 September 2026.)

Read article →
Who does Verifactu affect?

Only people who invoice through billing software (a SIF). If you invoice by hand or on paper, this specific obligation doesn’t apply to you.

Read article →
What percentage of my income should I set aside for taxes each month?

As a reference, between 15% and 30% of gross invoicing, on top of VAT, which is never really yours and should be set aside as soon as you collect it.

Read article →
How do I read the tax forms you file on my behalf?

Each form (130, 303, 390, annual return) covers a different obligation. We send you a copy of all of them, and if one raises questions, we break it down for you.

Read article →
What expenses can I deduct to pay less tax?

Anything necessary for your business and justified with an invoice: utilities, materials, social security contributions (if you’re self-employed), accounting fees, training, and more. We review it with you case by case.

Freelancers

How long does freelancer registration take?

One or two business days, if your paperwork is ready.

Read article →
Flat-rate or direct estimation regime?

Direct estimation usually applies, but for activities like hospitality, restaurants, or retail, the flat-rate (módulos) regime can apply instead. Get in touch and we’ll tell you which regime fits your business best.

Read article →
Is the annual income tax return included?

No, the annual income tax return is not included in the monthly fee. It costs €40 + VAT (€48.40 with VAT) separately.

Can I opt for the flat-rate (módulos) regime if my activity qualifies?

Yes, if your activity is on the allowed list and you stay under the invoicing limits.

Read article →
How often should I check my business’s accounts?

Quarterly is a good rhythm: enough time to spot a trend without reacting too late.

Read article →
How is the income tax I pay each quarter calculated?

You pay 20% of the year’s accumulated profit (income minus deductible expenses), minus whatever you’ve already paid in earlier quarters. We walk through an example on the blog.

Read article →
Can I deduct rent, electricity, or my phone if I work from home?

Yes: rent proportional to the space you use for your business, and for utilities (electricity, water, gas) 30% of that same proportion. We adjust it to your actual home.

Read article →
How much can I deduct for my car as a freelancer?

For income tax, only if the car is used exclusively for the business (or you’re a taxi, driving school, sales rep, or goods transporter): if you also use it for anything personal, you deduct nothing. For VAT, you can deduct 50% of the input VAT with barely any argument.

Companies (SL)

Do you handle accounting for an SL?

Yes.

Do you manage payroll?

Yes, we handle payroll and labor management.

Can you take over an SL that’s already running?

Yes, we handle the handover with your current accounting firm.

Do you help incorporate an SL?

Not yet. We advise you, but incorporation is handled by a notary.

How often should I check my company’s balance sheet?

Quarterly is a good rhythm: enough time to spot a trend without reacting too late.

Read article →
What’s the difference between a balance sheet and a profit and loss statement?

The profit and loss statement summarizes the net result (profit or loss) generated by your business over a given period. The balance sheet reflects your financial position at a specific point in time, detailing assets and liabilities to measure your business’s real solvency and net worth.

Read article →
How much share capital do I need to set up an SL?

From €1, though while it stays below €3,000 you need to set aside 20% of profit each year until reaching that figure.

Read article →
How long does it take to incorporate an SL?

With standardised bylaws, it can be resolved in a few days; with custom bylaws, it usually takes several weeks.
