How to pay less tax legally with structure

Paying less tax legally requires a serious choice: optimise residence, build a declared international structure or move your real base with substance.

Paying less tax legally starts with a serious decision: real residence, declared structure, clean banking and solid evidence before moving the business.

At Exentax we have spent years working with people fleeing the 47% IRPF plus social security. The good news is that honest paths exist. The less good news is that none of them consists in "not declaring".

Principle one: tax residency rules

The first thing to assume is that your country of residence taxes you on your worldwide income. It does not matter where your company is, where your clients are or where your bank is: if you live more than 183 days a year in a country with a worldwide income system (Spain, France, Germany, Mexico, Argentina, Colombia and most of Europe and LatAm), you pay there.

From that starting point, the paths to reduce the burden open in three big families: optimize within your country, change your residency or use international structures correctly declared.

Path one: optimize without moving

Before thinking about complex structures, it is worth reviewing the basic tools that already exist in your country and that many people do not use.

In Spain, for example:

Right legal form: switching from autónomo to a limited company when income exceeds ~EUR 60-80k can cut the combined IRPF + quota bill.
Investment and training tax credits.
Corporate pension plans and contributions.
Flexible compensation for employees and working partners: meal tickets, transport, training, health insurance.
Capitalizing unemployment benefits when starting self-employment.
Impatriate regime (Beckham) if you return to Spain after several years abroad.

These tools do not eliminate taxes but can cut the bill 5-15 points without changing anything structural.

Path two: favorable tax residency

The most drastic and most legal way to pay less is living in a country with lower fiscal pressure. It implies actually relocating, breaking the previous residency and meeting presence days at destination. Some real options today:

Andorra: 10% IRPF, 10% CIT, 4.5% VAT. Minimum rates, high quality of life, border with Spain and France. Requires active or passive residency visa, minimum 183 days of presence.
Portugal: the classic NHR regime is already closed; the new IFICI regime is more restrictive but still exists for scientific and innovation profiles. Beyond that, Portugal is no longer the paradise it was.
Italy: impatriate regime and the EUR 200,000 flat regime for high net worth.
Greece, Cyprus, Malta: specific regimes for new residents.
UAE (Dubai, Abu Dhabi): real 0% personal income tax with residency visa and presence.
Paraguay, Uruguay, Panama, Costa Rica: territorial systems and accessible residencies, especially for Spanish speakers.
United States: 0% state in some states without income tax (Florida, Tennessee, Nevada), but high federal IRPF. Only fits if you fit the US system.

Becoming a tax resident in another country is the only way to structurally and permanently reduce IRPF. It implies relocating, integrating and meeting the calendar.

Path three: declared international structure

If you do not want to relocate but your activity is clearly international (clients outside your country, digital model, income in several currencies), a corporate structure abroad can optimize corporate taxation, not personal.

The typical case is the US LLC for non-residents:

a documented US federal outcome through <a href="/en/blog/llc-pass-through-with-real-tax-structure">pass-through</a>.
Profits flow to the owner and are declared in their country of residence.
Allows deducting all business expenses before paying tax in your country.
Working international banking and gateways (Mercury, Stripe USA, Wise).
Neutral and professional reputation.

How much do you really save? It depends on the country. For a Spanish autónomo billing EUR 80,000 per year, replacing the autónomo model with a well-managed LLC can move the tax burden from ~37% combined to ~20-25% effective, depending on expenses, deductions, distributions and year-end planning. For higher bases, the comparison must be made against a marginal rate that can reach 54% in certain regions. It is not always 0%, but the saving can be very real.

Path four: legitimate combinations

For more complex profiles, paths can be combined:

US LLC + Andorran residency: a frequent combination for European entrepreneurs.
International holding + local operating subsidiaries: for groups with multiple businesses.
IP restructuring into a company with controlled royalties (carefully, given BEPS).
Multi-year dividend distribution to manage IRPF brackets.

These combinations require specialized advisory and honest design. They are not recipes; they are bespoke constructions.

What does not work and is worth dismissing

Not declaring the foreign account or company: European CRS environments leave automatic reporting trails; US banking works differently, but KYC, FATCA, BSA, legal requests and tax obligations do not disappear. Financial privacy is not invisibility.
Nominees and front owners: in addition to being illegal, it does not deceive the tax authority and breaks any real asset shield (<a href="/en/blog/nominee-llc-owners-risk-and-legal-alternative">complete guide</a>).
Officially living in one country and really in another: the 183-day test, center of vital interests and digital traces (cards, phones, social networks) leave footprints.
Shell companies without substance: the effective management in your country turns them into local tax residents.
Magic-tax promises: they do not exist for residents in developed countries without facts, residence and documentation that support the position.

How to choose your path

A sensible roadmap:

Calculate your real current bill: IRPF + Social Security + net VAT borne, all together. Without that number, any comparison is theoretical.
Define what you are willing to change: structure only, residency, or both.
Estimate the net saving of each path after operating costs (company, advisory, life in another country).
Check the fiscal risk: effective control, international transparency, exit tax, substance.
Consult specialized advisors before acting: a poorly made decision is harder to recover than a well-made one.

The balance we recommend

For most clients reaching Exentax with the question "how do I pay less without having to hide?", the most balanced combination is usually:

US LLC to channel the international activity (a documented US federal outcome, working banking, gateways).
Monthly bookkeeping to optimize deductible expenses.
Full disclosure in your country of residence: effective control, dividends, transparency.
If it fits, consider relocating to a favorable jurisdiction (Andorra, UAE, Paraguay, Portugal IFICI).

This can be 0% when residence, activity, banking and local rules genuinely fit. In other cases it will not be zero, but it can still be legal, sustainable, scalable and materially better than the starting point. In most well-designed scenarios, the difference is 10-20 points over time; for many founders, that is the gap between working forever and building wealth.

Real scenarios where How to pay less tax legally with structure applies

Case 1: employee starting freelance work alongside.

US LLC with correct declaration in country of residence. You leverage legitimate deductions, separate wealth and cut burden without changing your life. Annual cost: under 1,000 EUR.

Case 2: consolidated entrepreneur willing to live 6 months abroad.

Move tax residency to a low-tax jurisdiction (Andorra, Panama, UAE). Substantial fiscal saving but requires serious planning, clean break with the prior country and real commitment to the new one.

Case 3: executive with significant wealth and heirs.

Combination of wealth holding + succession planning + possible partial expatriation. Complex structure but clearly legal, with savings accumulated over decades that fully justify upfront advisory investment.

FAQ on How to pay less tax legally with structure

What is the simplest legal path to reduce taxes?

Structure your activity through a US LLC, declare it correctly in your country of residence and use legitimate deductions. Without relocating, this combination cuts total burden by 5-15 points compared to traditional self-employment.

And if I want to pay literally zero?

You need facts that support it: effective residence in a low/no-tax jurisdiction, income that is not taxed locally, clean banking, source-of-funds evidence and a real break from the prior residence. Paying zero can be legal; pretending nothing changed while living in the same tax system is not.

How long does it take to implement an efficient legal structure?

Between 2 and 6 months for a well-formed LLC, with an operational bank account and basic compliance. If residency change is involved, add 6-18 months to consolidate the new tax residency.

Are tax amnesties an option?

Only if you have past unresolved situations. For forward planning, amnesties are not a tool but a last resort. Better to structure correctly from the start.

Is it worth advisory before acting?

Always. One hour of professional advice before incorporating saves years of problems and thousands in penalties. Initial structure mistakes are the costliest and hardest to fix. With Exentax, the deadline is tied to a responsible person, a record and a practical action.

Is there a risk of regulatory change invalidating my planning?

There always is, but smaller than it seems. Consolidated regimes (Andorra, Panama, Estonia, LLC) have been operating for decades. Changes typically have a vacatio legis and respect consolidated situations. Structuring well and reviewing annually is the best protection.

Practical close on How to pay less tax legally with structure

Legal paths to pay less tax do exist. None consists in not declaring. The most effective ones combine international structure, fiscal planning and, when possible, favorable residency. The choice depends on your life, your income and your tolerance for change.

Exentax does not sell a company in isolation. We model residence, personal tax, LLC treatment, banking, distributions, evidence and review risk before recommending anything. If you want to reduce tax pressure with structure rather than improvisation, <a href="/en/book">book a strategic review</a>.

Tax efficiency starts with residence and source

The legal minimum-tax paths read more usefully when they're treated as a stable structural mapping between residence, value creation and customers, than as a marketing trick. The mapping doesn't change with the season, and a short dated note in the personal folder with the three axes makes the position reviewable.

> <a href="/en/book">Review my case</a>

The legal route to a lower burden starts with residence, source of income and documentation. A structure can reduce tax only when the facts support it; if the file cannot explain control, activity and money flows, the saving becomes fragile.

The legal low-tax path starts with the owner’s real residence, then activity, banking, distribution policy and documentation. A low-rate entity without that order becomes a fragile shortcut, not planning.

How to pay less tax legally in Spain:

IRPF deductions, pension plans, Beckham regime and US LLC as a legitimate planning tool

Before thinking about moving abroad, it pays to squeeze the legal levers already available in Spain that most taxpayers do not even apply. This block lays out the four real avenues for, with a checklist by profile at the end.

Lever 1: IRPF deductions the average resident leaves on the table

Personal pension plan contributions (capped at EUR 1,500 a year after the reform) and especially employment pension plans sponsored by the employer, allowing extra contributions up to EUR 8,500 a year without penalising the employee.
Maternity, large family, dependent descendants and ascendants and disability: state and regional deductions that many forget to claim.
Investment in newly created companies: 50 % state deduction on EUR 100,000 a year if you meet the article 68.1 LIRPF requirements.
Donations to organisations under Ley 49/2002: 80 % on the first EUR 250 and 40 % on the rest, plus loyalty incentives.
Primary residence rentals: regional deductions in Madrid, Catalonia, Valencia, Andalusia and others, with brackets by age and income.

Lever 2: employment pension plans and life annuities

The reform shifted weight from individual to employment pension plans. If you run your own LLC and live in Spain, channel part of the management compensation into an employment pension plan through your own structure where legally viable. Life annuities under article 38 LIRPF allow reinvesting capital gains tax free if you are over 65 and meet term and form conditions.

Lever 3: Beckham regime for inbound taxpayers

Ley 28/2022 expanded the Beckham regime to digital professionals with an online work visa and covers six full tax years. You are taxed at 24 % up to EUR 600,000 of employment income and non Spanish income is left out of the general base. Apply within six months of registering with social security; you must not have been a Spanish resident for the previous five years.

Lever 4: US LLC as a legitimate planning tool

A properly declared LLC lets you separate assets, professionalise management and, combined with a tax treaty, materially lower your IRPF bill when activity is international. The <a href="https://petete.tributos.hacienda.gob.es" target="_blank" rel="noopener">DGT</a> V0290-20 doctrine accepts attribution as capital or business income depending on the partner's role. The LLC is never a wrapper to "not file" in Spain: with FATCA and the DAC8 progression, everything surfaces. Its value lies in operations, financing and legal optimisation, not concealment.

Checklist by profile

Employee: maximise the employment pension plan, review regional deductions, review flexible compensation (childcare voucher, training, health).
Self-employed: tidy up deductible expenses, assess switching to SL above EUR 60,000-80,000 net profit, consider the LLC as an international layer if your client base is global.
SL owner: blend salary and dividends taking advantage of the savings base, structure car and housing with caution under DGT rules.
LLC owner resident in Spain: file clean Modelo 100 and Modelo 720 where applicable, optimise within the legal frame and avoid opaque structures.
