A Year Without a Gestoría: What You Learn Doing Your Own Bookkeeping as a Freelancer

Last June, a freelancer we know told his gestoría (a tax/accounting firm) he wasn’t renewing. He’d spent four years paying 150 euros a month for a service that consisted of: he sent them the invoices, they filed four returns a year, and if he asked something they answered in 48 hours in a language that needed translation.

Eighteen hundred euros a year. For four quarterly forms and an income tax return. It’s not that they did it badly: it’s that, for his case (a fiscally very simple activity), he felt he could handle it himself.

Before going on, an important clarification: a good gestor is a great option, and for most freelancers it’s the most sensible decision. It saves you time, covers your back, flags things you wouldn’t spot and frees your head to focus on your business. This article isn’t about “drop your gestoría”. It’s about a more honest question: in which cases can a freelancer do their own bookkeeping, and what does it really involve? Because going without a gestor only pays off if you have two specific things to spare: time and inclination.

Today, a year later, for him it has worked. But the first three months were tough, and he’s the first to say he wouldn’t recommend it to just anyone.

Why, in his case, he decided to handle it himself

It wasn’t an impulsive decision: he’d been thinking about it for a year, and his specific situation (a gestoría that processed the bare minimum and a very simple activity) gradually nudged him. The reasons, always referring to his case, not to gestorías in general:

Little proactivity for his profile. His gestoría just processed what he sent. A proactive gestor flags a deduction you’re not using, suggests a change of contribution bracket, or tells you “this quarter you’ll owe a lot, get ready”. If you have one like that, it’s gold; for him, with such a simple activity, they didn’t add that extra.

The odd review on his part. On two occasions he spotted small discrepancies in the returns (an expense in the wrong quarter, a mislaid invoice) and amendments had to be filed. It happens to anyone (also when you do it yourself), but it made him think that, if he was going to be on top of it anyway, maybe he could just handle it directly.

Doubts he wanted to resolve himself. When he asked something specific, he preferred the answer with the regulation in front of him. It’s a matter of style: some people want to delegate and forget (that’s what the gestor is for) and some enjoy understanding the why. He was in the second group.

The price, for his usage. For the little he needed (four simple quarterly returns in simplified direct assessment, no employees, no intra-community operations), it paid off to spend a few hours and keep that money.

What you actually have to do each quarter

This is the scary part before taking the leap: the list of tax obligations. It sounds unmanageable at first glance, but in practice, for a simple freelancer, it’s this:

Each quarter (before 20 April, July, October; 30 January for Q4):

1. Modelo 303 (IVA): add up the IVA you’ve charged, subtract what you’ve paid, the difference is what you pay in. One form, seven boxes with data.

2. Modelo 130 (IRPF): 20% of the accumulated net yield, minus what you’ve already paid in previous quarters and minus any withholdings your clients have applied. Three relevant boxes.

3. Modelo 111 (withholdings, only if you pay other professionals): if you have no collaborators or employees, you don’t file it.

Once a year (April-June):

4. Income tax return: we all do it, freelancers and employees. With your data kept properly during the year, filling it in is just a matter of transferring numbers.

5. Modelo 390 (annual IVA summary): it’s a summary of the four 303 returns for the year. If you’ve filed the quarterly ones correctly, it’s copy and add.

Record books (mandatory but with no periodic filing):

6. Issued invoices book and received invoices book. They’re not filed anywhere unless the Spanish Tax Agency (Agencia Tributaria) asks for them in an inspection. But you have to keep them up to date.

That’s all. Five forms a year and two books. It’s not aerospace engineering.

The first quarter: pure terror

The first quarter he filed on his own was stressful. Not because it was technically hard, but because every click on the sede electrónica (the online tax office) raised the question “what if I get it wrong and get fined?”.

What he did:

Study before acting. He read the regulations for the 303 and the 130. Not the whole IVA law (that’s inhuman), but the form instructions and three or four practical guides. If you’re thinking of taking the leap, start with the guide on how to fill in modelo 303.

Use the draft as practice. The sede electrónica lets you fill in the form and save it as a draft without filing. He filled it in, reviewed it three times on three different days, and only then hit submit.

Compare with the previous quarter. He asked the gestoría for a copy of the returns from the last quarter they filed. He used them as a reference to check his numbers made sense.

Result: he filed it correctly. No errors. The IVA matched his records to the cent. The 130 too.

The mistakes he made

It wasn’t all perfect. In a full year managing his own bookkeeping, he made three mistakes. None serious, all fixable.

Mistake 1: he forgot a withholding

In the second quarter an invoice arrived from a freelance collaborator carrying a 15% IRPF withholding. Note the detail, which is the one he missed: the party who withholds is not the one issuing the invoice but the one paying it. That is, he paid the collaborator the amount minus that 15%, and that 15% was his to pay in to the Agencia Tributaria by filing the modelo 111. He didn’t, because it hadn’t occurred to him that receiving an invoice with a withholding made him the one obliged to pay it in.

He realised two weeks after the deadline. He filed the 111 late with a minimal surcharge (less than 20 euros because the amount was small). Lesson learned: every time you receive an invoice with a withholding, you have a new obligation.

Mistake 2: he miscategorised an expense

He put an entertainment expense (a meal with a client) as a general expense instead of as a “client hospitality expense”, which has a deductibility limit of 1% of net billing. It had no practical consequence because he was nowhere near the limit, but if the Agencia Tributaria had reviewed it, he’d have had to justify it.

Since then he categorises more carefully from day one. It’s much easier to categorise well when you record the expense than to try to reconstruct three months later what each restaurant receipt was for. And there’s a detail he learned late: he’d bring back the till receipt and nothing else, and a receipt doesn’t let you deduct the VAT unless you ask the restaurant to put your tax number on it while you’re paying.

Mistake 3: he filed the third quarter’s modelo 303 a day late

The deadline was 20 October. He filed it on the 21st. One day. The surcharge for late filing without a prior demand is 1% of the amount (if within a month’s delay). In his case, about 14 euros. He paid and learned to set the alarm a week before, not the day before.

The freelancer’s tax calendar is now stuck (virtually) on his desk.

What’s easier than it looks

The modelo 303 itself. It’s a long form, but most of the boxes don’t apply to you: for a services freelancer with IVA at 21%, the rest are zeros.

The record books. Beforehand they look like a bureaucratic monster. In practice, if you keep your invoices organised with any tool, the record books generate themselves.

The sede electrónica. It’s ugly and dated, but it works. With Cl@ve PIN or a digital certificate, filing a return takes five minutes. The form even has validations that warn you if something doesn’t add up.

Correcting errors. If you make a mistake, you file a complementary return (if you underpaid) or a rectifying one (if you overpaid). It’s not the end of the world. The police don’t come.

What’s harder than it looks

Remembering everything. It’s not that it’s technically hard. It’s that you have to remember. The quarter’s deadline, the invoice that arrived at the end of the month and you don’t know if it goes in this quarter or the next (it’s assigned by invoice date, not payment date), the supplier who sent you the invoice without IVA and you have to check why.

The one-off doubts. “Can I deduct this?” “Does this go with IVA or without?” “Is this expense home or professional?” With a gestoría, you asked (and sometimes they answered something useful). Without one, you have to look it up yourself. Most answers are on the Agencia Tributaria website or specialised forums, but it takes time.

The fourth quarter. Q4 is more complex than the other three because it includes the annual summary (modelo 390) and, depending on your situation, annual regularisations. It’s the quarter that takes the most time the first time.

The income tax return. Not because it’s hard, but because of the amount of data you have to transfer. If you keep your numbers well during the year, it’s a formality. If not, it’s a reconstruction nightmare.

The real savings

Raw numbers:

Net saving: 1,716 euros the first year. In subsequent years, with no rookie errors, it’ll be 1,750 euros.

The time invested (30 hours a year) works out to about 2.5 hours a month. If you value your hour at 50 euros, that’s 1,500 euros of “opportunity cost”: the saving is still clear, but the money isn’t what weighs most.

The real benefit: understanding your business

This is the argument that can’t be quantified but weighs more than the economic saving:

You know exactly how much you earn. Not approximately. Exactly. Every month. Without waiting for the gestoría to do a close-out.

You spot problems sooner. When a client takes longer than usual to pay, you see it in your cash flow immediately. With a gestoría, many don’t find out until the account is in the red.

You make better decisions. You can ask “if I subscribe to this new tool, how does it affect my quarter?” and answer it yourself in five minutes. With a gestoría, you had to wait for them to tell you whether it “fit”.

You negotiate your rates better. You know how much you need to bill to live with the margin you want. Not an estimate. An exact number based on your real expenses.

When a gestor is worth it (and when you can go without)

For most freelancers, a good gestor is the best decision. Paying for one makes complete sense the moment any of these is true:

• You have employees. Payroll and social contributions more than justify a professional.
• You do frequent intra-community operations or sell outside the EU: IVA gets complicated and a mistake is expensive.
• You have an SL (a limited company): commercial accounting is mandatory and far more complex than a self-employed individual’s.
• You’re on módulos, cash-basis or any special regime: the rules change.
• You’re short on time, or you simply don’t feel like it. This is the most important (and most honest) filter: your time is worth something, and the peace of mind of delegating is too. If you’d rather spend those hours on your business or your life, a gestor’s ~150 euros a month is money well spent.

Going without a gestor only pays off in one very specific case: you’re a fiscally simple freelancer (direct assessment, no employees, domestic activity, moderate billing) and, both at once, you have the time and the inclination to understand your own numbers. And if you handle it yourself one year and your activity gets more complex the next, you can always hire one again.

How does Cuéntamo help with this?

Dropping the gestoría doesn’t mean getting by with a spreadsheet and the tax agency’s website open in another tab. The part that felt terrifying that first quarter (knowing what to file and with which numbers) is exactly what Cuéntamo’s self-employed module automates.

From your transactions, Cuéntamo prepares the quarterly IVA and IRPF settlements, broken down by VAT rate and showing the amount to pay on each form. You mark the deductible expenses, link the invoices and the calculation updates on its own. No more reconciling collected VAT against paid VAT by hand.

You also keep the record-keeping ledgers the tax agency requires (income, expenses, capital goods and provisions) without building them from scratch. You import your invoices, link them to the bank transaction and the ledgers are ready in case you’re asked for them.

And here’s the other side, which matters: Cuéntamo also helps if you have a gestor. By keeping your transactions and invoices organised and categorised all year round, your gestor gets clean, reconciled information instead of a shoebox full of receipts. That saves them work, reduces errors and makes their advice more useful (because they can focus on advising you, not on keying in data). It’s not “Cuéntamo or a gestor”: for many freelancers, the ideal is Cuéntamo and a gestor, each doing what they do best.

You’ll find the concrete steps for each quarter in the guide on how to calculate quarterly VAT, and you can keep all of this inside Cuéntamo.

Frequently asked questions

Can I do my own bookkeeping as a freelancer without a gestoría?

You can, if you’re a simple freelancer in direct assessment, with no employees, with domestic activity and moderate billing, and, this is key, you have the time and inclination to do it. It’s basically five forms a year and two record books.

What do I have to file each quarter without a gestoría?

The modelo 303 for IVA and the modelo 130 for IRPF, and the modelo 111 only if you pay other professionals with a withholding. Once a year you have the income tax return and the modelo 390 (annual IVA summary).

How much do you save by dropping the gestoría?

In the real case we tell, the net saving was about 1,716 euros the first year, against the 1,800 euros a year the gestoría cost. In exchange, you have to dedicate around two and a half hours a month.

What happens if I make a mistake filing a form?

It’s not the end of the world: if you underpaid you file a complementary return, and if you overpaid, a rectifying one. Filing late without a prior demand carries a surcharge, usually small if you correct it soon.

When is it worth keeping a gestor?

For most freelancers, a good gestor is the best decision. It’s worth it whenever you have employees, frequent intra-community operations, an SL, any special regime or, simply, when you’re short on time or don’t feel like it. Doing it yourself only makes sense if you’re fiscally very simple and, at the same time, have the time and the inclination.

Figures for 2026. The IRPF withholding for professionals (15%) and the limit on client hospitality (1%) have been in force since 2015; the system of surcharges for late filing, since 2021 (Ley 11/2021).
