Set Aside for Taxes: How Much to Save from Every Invoice

Knowing how much to set aside for taxes from every invoice is what separates freelancers who sleep well from those who panic every quarter. When clients abroad do not withhold anything, the whole tax bill falls on you, and the only safe habit is to save a share of each payment the day it arrives.

The short answer: many freelancers in Spain start by setting aside 25–30% of every payment received, in a separate account, until they calculate their real rate. The right figure depends on your profit, expenses, social security and region. After your first year, compare the amount saved with what you actually paid and adjust the percentage.

The percentages here are planning examples, not tax calculations. Your tax depends on profit, deductions, region and personal situation. This is general information, not tax advice; ask a gestor for a precise estimate.

What taxes do you need to save for?

Tax or charge	Do you need to save for it?
Income tax (IRPF)	Yes. Foreign clients do not withhold it, so you pay through quarterly prepayments and the annual return.
VAT collected	If you charge VAT, it is not your money. Invoices to business clients abroad often carry none.
Social security	Yes, as a monthly contribution, which you can budget separately.
Local taxes	Depending on your activity; many freelancers are exempt.

For the overall picture, see taxes for freelancers with foreign clients in Spain.

A simple percentage method to set aside for taxes

Open a separate account used only for taxes.
When a payment arrives, immediately move a fixed percentage, for example 25%.
If you charged VAT, move the VAT in full, on top of the percentage.
Pay your quarterly returns from this account. See quarterly tax returns for freelancers.
After each quarter, check the balance against what you paid.

Example: set aside for taxes from one invoice

Item	Amount
Invoice paid by a client abroad	€2,000
Move to the tax account (25%)	€500
Remaining in the business account	€1,500
Of which, business costs and social security	depends on your numbers
Available for the buffer and your salary	the rest

If at year-end you owe less than you saved, the surplus becomes savings. If you owe more, increase the percentage.

How to choose your percentage

Low profit and many deductions: start lower, around 20%, and verify.
Average profit: 25–30% is a common range for autónomos.
High profit: 30–35% or more, because higher brackets apply.
Use your real numbers: see the examples in how much tax freelancers pay in Spain.

Social security is paid monthly, so many freelancers include it in the set-aside or budget it as a fixed cost. Whichever way you choose, do it consistently.

What if you are paid in another currency?

Calculate the percentage on the amount in euros at the time you receive and convert the money. If you keep dollars, convert the tax share in the same proportion. Keep a record of the exchange rate: see which exchange rate to apply. Read how to manage exchange rate risk to avoid surprises.

Quarterly check: is your tax account enough?

Prepare modelo 130 and 303 estimates at the start of each quarter.
Compare them with the balance in your tax account.
If there is a shortfall, increase the percentage.
If there is a surplus, keep it in the account until the annual return.
Repeat every quarter. Our finance spreadsheet for freelancers automates the set-aside.

Frequently asked questions about set aside for taxes

How much should I set aside for taxes as a freelancer?

Many autónomos in Spain start with 25–30% of each payment and adjust after checking their real tax.

Do I save for VAT too?

If you charge VAT, it belongs to the tax agency and must be saved in full. Invoices to business clients abroad often have no Spanish VAT.

Where should I keep the money?

In a separate account used only for taxes, so you do not spend it by accident.

What if I save too much?

The surplus stays as savings. It is safer to overestimate in the first year.

Does the percentage change with income?

Yes. Higher profit falls into higher brackets, so the percentage may need to rise.

Should social security be included?

Plan for it separately or include it in the set-aside, but do not forget it.

Final thoughts on set aside for taxes

The habit is simple: when you are paid, set aside for taxes immediately, in a separate account, with a percentage you review every quarter. Start with a prudent figure, add VAT if you charge it, keep social security in the plan and compare with your returns. That small routine removes the biggest source of financial stress in freelancing.
