Step-by-step

1
Open a digital account immediately for day-to-day use
Revolut, N26, Wise and the Spanish neobanks open accounts quickly on a passport and NIE, giving you a usable IBAN in days rather than weeks. This covers your first rent payment and utilities while a branch account is arranged.

2
Consider a Basque cooperative bank as well as a national one
Kutxabank and Laboral Kutxa are deeply embedded in Gipuzkoa, have branches in the small towns of the interior, and handle local payroll and provincial administrative arrangements as a matter of routine. For someone settling here rather than passing through they are often the better fit.

3
Insist on a resident account once you have the padrón
Non-resident accounts carry higher fees and require a periodically renewed certificate. Once registered on the padrón you qualify as resident for banking purposes — bring the certificate and check which product was actually opened.

4
Compare maintenance fees carefully
Spanish current accounts commonly carry monthly or quarterly maintenance charges, often waived if you direct your salary and a set number of direct debits into the account. The waiver conditions vary a lot between banks and determine what the account actually costs.

5
Set up domiciliación, and point the tax one at the right treasury
Rent, utilities, phone, taxes and social security all run on direct debit. Note that your income tax here is paid to the Diputación Foral de Gipuzkoa rather than the state agency, so the portal, the payment references and the calendar are different from the rest of Spain.

6
Establish the foral position on foreign-asset reporting
Gipuzkoa has its own foreign-asset declaration regime administered by the Hacienda Foral rather than by the Agencia Tributaria. The obligation is real, the deadline is its own, and it is filed with the provincial treasury. Confirm the current form and deadline with a Gipuzkoa-based adviser rather than assuming the state Modelo 720 rules apply unchanged.

Things most newcomers don’t know

Your tax payments go to Gipuzkoa, not to the Spanish state, and the plumbing is different.

Because the Diputación Foral collects income tax here, the portal, the credentials, the payment references and the deadlines all differ from the Agencia Tributaria's. Setting up a direct debit for a state tax payment you do not owe, or missing a foral deadline because you were watching the state calendar, are both common first-year mistakes. Bookmark the Gipuzkoa site rather than the national one.

The cooperative banks here are part of an actual economic model, not a branding exercise.

Laboral Kutxa grew out of the Mondragón cooperative federation, the largest worker cooperative group in the world, whose member firms employ a substantial share of Gipuzkoa. Kutxabank descends from the provincial savings banks. Both have branch coverage in valley towns the national banks have abandoned and are used to handling local employers' payroll. If you will work for a cooperative — which here is a real possibility — the fit is closer than a national brand's.

The resident/non-resident distinction is a real and recurring cost.

A non-resident account carries higher fees and depends on a certificate that must be renewed; if it lapses, banks can restrict the account. Once you are on the padrón you qualify as resident. Many newcomers open a non-resident account on arrival, never convert it, and pay more for years.

Heating and damp, not cooling, are the seasonal bills here.

Most Spanish cities are a summer air-conditioning problem. Donostia is an oceanic climate with mild summers and damp cool winters, so the seasonal cost is heating and dehumidifying. Older flats in the Parte Vieja and in Egia can be genuinely damp, and a December-to-March heating bill is the line most newcomers from southern Spain have not budgeted for.

Common mistakes to avoid

Watching the Agencia Tributaria's calendar when your obligations run to the Hacienda Foral de Gipuzkoa.
Assuming the state Modelo 720 rules describe your foreign-asset reporting obligation here.
Opening a non-resident account and never converting it once you are on the padrón.
Not asking what conditions waive the monthly maintenance fee.
Budgeting for a Spanish cooling bill and being caught by a Donostia heating one.
