Paying less tax legally in Spain: expenses, residence and a US LLC

Plan your tax position in Spain with expenses, investment, residence and a US LLC. Compare full costs and choose your business structure with Exentax.

If you want to pay less tax legally, start with the number that matters: how much your business leaves available for you and for future investment. That depends on expenses, tax residence, business structure and operating costs, not just the headline rate in another country. A US LLC can be an important part of the answer when you trade, contract or invest internationally.

This guide concerns business owners who are tax resident in Spain, or considering a genuine relocation. It separates three decisions: using the rules available today, choosing the right business structure and assessing a change of residence. Exentax works through those decisions using your figures and plans, so the company supports the life and business you want to build.

Three different ways to improve your after-tax position

Reducing tax means an applicable rule lowers the amount due. Deferring tax changes when an amount becomes payable, where the rules allow it. Improving operating margins means spending less on collections, currency exchange, financing or administration. All three can be valuable, but they are different results.

A USD account that avoids unnecessary currency conversions improves your margin. An allowable business expense affects the profit calculation. A personal tax credit can reduce the tax bill. Cash retained in a company raises a separate question: which person or entity is taxed on the profit, and when?

Compare the whole arrangement over more than one year

Use the same revenue, expenses, investments and personal cash requirements for each option. Include formation, annual maintenance, filings, banking and professional fees. Separate one-off costs from recurring commitments, then calculate the second year as well.

A marginal rate applies to an additional slice of income; an effective rate relates a tax bill to a stated base. Comparing a personal marginal rate with a company's headline rate does not show the owner's final position. VAT collected from customers also needs its own treatment: it should not simply be added to income tax as another tax on the same profit.

First route: make the existing tax calculation work properly

Before changing country or legal form, examine how your current profit is calculated. Advertising, professional services, business tools, insurance, processing fees and other genuine operating costs may affect taxable income.

The Spanish Tax Agency's guidance on deductible expenses requires a business connection, appropriate records, correct timing and supporting evidence. An invoice identifies the transaction; the contract and payment help establish what happened. Paying with a business card is not, by itself, the test for deductibility.

Expenses, base reductions and tax credits work at different stages

An allowable expense enters the business profit calculation. A tax-base reduction operates on the relevant base. A tax credit reduces the tax liability. A pension contribution, a business purchase and a regional personal tax credit therefore cannot be treated as three interchangeable discounts.

Individual and employment pension arrangements have their own conditions and combined limits. Personal, family, regional and investment incentives depend on the tax year and the taxpayer's circumstances. The useful exercise is to identify what you actually qualify for and retain the evidence needed to claim it.

Plan purchases around their business value and recognition date

A subscription used during the year may be a current expense. Equipment used over several years may be recognised as an asset and depreciated. Inventory, prepayments and improvements also require a distinction between payment, consumption and the accounting period.

Before a significant purchase, establish the commercial benefit, cash cost and amount recognised this year. Spending money solely to obtain a deduction still uses cash. Good planning supports investment that the business needs, with a clear view of both liquidity and tax treatment.

Worked example: profit is not the same as available cash

Assume a business earns and collects EUR 100,000, pays EUR 30,000 of allowable current expenses and buys equipment for EUR 12,000. For this example, allowable depreciation for the year is assumed to be EUR 3,000. The owner draws EUR 20,000 for personal use; this is not salary or payment for an invoiced service.

This is an illustrative calculation, not a client case or an income-tax assessment. Opening cash is zero. VAT, social contributions, profit taxes, financing, exchange differences and other adjustments are excluded. The EUR 3,000 depreciation is an assumption, not a statutory rate for all equipment.

Profit is EUR 67,000; closing cash is EUR 38,000. Investment, depreciation and the personal drawing explain the difference. The applicable tax calculation comes afterwards, using the relevant classification, jurisdiction and personal circumstances.

Reinvestment needs its own budget and tax treatment

Hiring, developing a product or acquiring assets can strengthen the company. Distinguish an allowable current expense from a depreciable asset and a cash reserve earmarked for a future purchase. Keeping money ready to invest is not the same transaction as making the investment.

For a fiscally transparent entity, income attribution may occur independently of a distribution. A company taxed in its own right follows a different analysis. An investment policy should therefore begin with the structure's actual rules and the capital needed to carry out the plan.

Second route: choose the business structure for the work it must do

There is no universal turnover threshold at which a Spanish SL or a US LLC becomes cheaper. Net profit, members, personal drawings, activity, recurring costs and the countries involved all matter.

A high-revenue business with narrow margins may need a different arrangement from a consultant with few expenses. Hiring staff, bringing in a partner or building an asset portfolio can justify a structure before revenue becomes particularly large. The comparison should account for those commercial objectives.

Where a US LLC adds practical value

An LLC provides a company through which to contract, organise ownership, separate business funds and develop banking and commercial relationships. Its Operating Agreement can document ownership and management responsibilities. Proper administration gives the business continuity beyond individual transactions.

Its value can also come from a purposeful combination of providers: one account for collections, another for international payments and another for reserves or investment, subject to eligibility. We coordinate international banking and payment methods around the currencies, customers, suppliers and cash needs of the business. Each account should earn its place.

Read classification, source and residence together

The IRS classifies an LLC according to membership and effective elections. A Single-Member LLC is a disregarded entity by default for federal income-tax purposes; the general default for multiple members is partnership treatment unless another classification is elected. Foreign-owned describes ownership, not an additional tax classification.

For services, the IRS generally determines income source by where the work is performed, not the customer's or bank's location. US business activity, ECI, other income and filing requirements then need consideration. Service revenue, investment income and product sales do not necessarily follow the same source rule.

In Spain, the DGT resolution of February 2020 sets the criteria for treating foreign entities under income attribution. These concern taxation at entity level, attribution independently of distributions and preservation of the income's nature. Our guide to the resolution and US LLCs develops the three tests.

Coordinate relief where the same income is taxed twice

A treaty and domestic foreign-tax-credit rules can provide relief when their conditions are met. Identify the recipient, income category, residence and tax paid before calculating relief, including the relevant limits and supporting records.

The US-Spain tax treaty guide for LLC owners explains that sequence. The benefit comes from applying the appropriate rule to the transaction, not automatically deducting every foreign withholding from the Spanish bill.

Third route: assess a genuine change of tax residence

Relocation can materially change taxation and access to markets. It is also a personal and business decision. Housing, family, work, immigration permission, healthcare and the cost of maintaining the company belong in the calculation.

For Spain, Article 9 of the Personal Income Tax Act considers presence exceeding 183 days in the calendar year and, alternatively, the principal centre of economic activities or interests. It also includes a family presumption and rules concerning absences. Immigration permission and a tax-residence certificate establish different things.

Model the relocation year separately

Map departure and arrival dates, where work takes place and what happens to contracts, ownership interests and outstanding income. If two countries regard the individual as resident, examine the relevant treaty and its residence criteria. Our international tax-residence guide explains the planning work.

Compare estimated savings with accommodation, travel, insurance, professional fees and business adaptation. A workable arrangement supports your intended lifestyle while preserving investment capacity. The destination's headline rate is only one input.

Moving to Spain may justify reviewing the inbound regime

The special regime under Article 93, often called the Beckham regime, has eligibility, election and duration requirements. It covers specified employment, professional, entrepreneurial and investment circumstances, each requiring its own assessment.

Where conditions are met, the regime can apply in the year residence changes and the following five tax years. It is not a general option for people already resident in Spain. The comparison must reflect income categories, circumstances and periods rather than a single advertised rate.

Your tax-planning review: figures, options and implementation

We start with your activity and plans: what you sell, where you work, who buys from you, whether there are partners and what you want to build. We then check the figures, keeping confirmed information separate from forecasts.

The initial material is usually straightforward: your latest return, a revenue and expense summary, planned investment, countries of activity and personal cash requirements. If you already own an LLC, we add formation documents, classification, accounts and available filings. You do not need a perfect forecast to start a useful conversation.

What a meaningful comparison should contain

The review should explain the current position, relevant alternatives, assumptions and first-year and recurring costs. It should also show how each option affects contracts, banking, distributions and administration. You should be able to follow the calculations.

Keeping the present arrangement, adopting an LLC or preparing a staged relocation can all be evaluated. If you operate from Spain, our guide to using a US LLC while resident in Spain places those options in context. An existing business may also need a carefully planned transition from Spanish self-employment to an LLC structure.

Put the agreed structure into operation

Once scope is agreed, Exentax coordinates formation or reorganisation, documentation, EIN, banking and the obligations included in the engagement. We establish what the team handles, what information you supply and where coordination with your other advisers is needed.

Follow-up matters when the business changes: another member, a hire, a new country, an investment or a different pattern of collections. Reviewing those changes keeps the arrangement useful. You work with a team that knows your circumstances, with practical help beyond formation.

Design my international tax strategy

Frequently asked questions about tax planning and LLCs

Can I reduce tax without changing residence?

Yes. Allowable expenses, tax-base reductions and credits may apply to your circumstances. Your legal form and operating costs also deserve review. Savings are calculated from your figures; forming another entity does not replace that assessment.

Is there a minimum turnover that makes an LLC worthwhile?

There is no universal figure. Profit, members, international operations, investment needs and maintenance costs matter alongside revenue. The comparison should include the owner's available money and the structure's full cost.

Does reinvesting profit mean there is no tax?

Reinvestment can have tax consequences depending on the expense or asset acquired and the timing rules. A cash reserve is not an expense. Transparent entities may attribute income without a distribution; other classifications require a different analysis.

What does Exentax need to review my position?

A summary of your activity, residence, income, expenses and objectives is enough to begin. The team then identifies missing documents and the scenarios worth calculating before you form, reorganise or relocate your structure.

Choose a company that improves the business as well as the numbers

Sound planning brings together tax, investment capacity and everyday operations. An LLC can be a valuable company for contracting, collecting revenue and organising an international business. The outcome should be clear figures, defined responsibilities and an arrangement you can use with confidence.

Exentax helps turn a broad wish to pay less tax into a specific decision: what stays, what changes, what it costs and how it will be implemented. That is how a tax-planning possibility becomes a working business structure.
