IRPF deductible expenses: activity under direct estimation

Searches for IRPF deductible expenses for the self-employed in Spain often mix two worlds. This guide covers the economic-activity expenses that reduce IRPF net yield when you determine that yield under direct estimation (normal or simplified modality). It leaves out deductible employment expenses under article 19 of the IRPF Law, the reduction for employment income, the residual habitual-home deduction for employees, and tax-base reductions that sit outside the activity-yield calculation.

Under direct estimation for IRPF, the net yield of the economic activity is calculated as the difference between computable gross income and deductible expenses that are properly evidenced and recorded in the accounts or in the mandatory record books; those expenses are the activity’s expenses, not the employment-income boxes for employees. AEAT, normal direct estimation; Law 35/2006 on Personal Income Tax, articles 16, 28 and 30.

This guide refers to Spain’s common tax territory and to individuals who are entrepreneurs or professionals under direct estimation. It does not cover objective estimation (modules), Corporation Tax, the Basque Country, Navarre, the Canary Islands with IGIC, Ceuta or Melilla. The information is general: it does not turn a particular expense into a deductible one or replace a review of your file.

Which question this guide answers (and which it does not)

The useful question here is: which of my activity’s expense concepts reduce IRPF net yield under direct estimation? The AEAT publishes a map of rubrics (purchases, wages, employer Social Security, the holder’s cuota, rent, supplies, independent professionals, insurance, finance costs, amortization, holder subsistence, other taxes, among others) and a summary table of income minus expenses. AEAT, deductible expenses under direct estimation; AEAT, summary table.

How you evidence an expense (invoice versus reality, the file, VAT/IRPF/Corporation Tax cross-checks) is already covered in tax-deductible business expenses in Spain. This page does not rewrite that chapter. When evidence matters, we link out. The focus here is what lowers the activity’s net yield.

The choice between the normal and simplified modalities, and the 5% hard-to-justify item, are covered in normal or simplified direct estimation. The simplified amortization table is in simplified direct estimation amortization table.

Minimum requirements before you look at the rubric

Appearing on an AEAT list does not make the receipt deductible. For an expense to be tax-deductible under direct estimation it must be connected with the activity carried on, recorded in the accounts or in the mandatory record books, correctly allocated and properly supported. AEAT, deductible expenses under direct estimation; AEAT, requirements for a deductible expense.

Deductibility depends on correlation with income: if you show that the expense arose in carrying on the activity and relates to earning income, it may be deductible on the legal terms; if there is no connection or the proof is weak, it is not. The invoice is the primary supporting document, but it is not privileged proof that the transaction was real. AEAT, requirements for a deductible expense. How to build the evidence file is in tax-deductible business expenses in Spain.

To place an expense in the activity yield, first check that it is connected with the activity, properly supported and recorded in the accounts or record books; then locate it in the matching AEAT rubric (purchases, staff, holder’s cuota, rent, supplies, professionals, insurance, finance, amortization, holder subsistence or other taxes) and separate what must stay out as a personal expense or as a different employment-income rule. AEAT, requirements for a deductible expense.

Map of activity expenses that usually reduce IRPF

The AEAT summary table starts from operating income and similar items and subtracts, among other lines, purchases and consumptions, wages and salaries, employer Social Security, Social Security or alternative mutual contributions of the holder, indemnities, staff subsistence, other staff costs, holder subsistence incurred in the activity, rent and royalties, repairs and maintenance, supplies, independent professional services, insurance premiums, other external services, finance costs, input VAT in specific cases, other deductible taxes, amortization and, depending on the modality, provisions or the simplified 5% package. AEAT, summary table; AEAT, deductible expenses under direct estimation.

Purchases, consumptions and stock variation

Materials, merchandise and other operating consumptions enter when they are used in the activity and correctly recorded. Stock variation adjusts period consumption: an increase in closing stock is treated as income in the table; a decrease, as a higher expense. AEAT, summary table. If you buy for private use and for the business on the same ticket, the problem is not the rubric: it is separating the activity share.

Staff charged to the activity

Wages, employer Social Security, indemnities, employee subsistence and other staff costs are rubrics for anyone with payroll staff or employed collaborators. AEAT, deductible expenses under direct estimation. Do not confuse Social Security you pay for your workers with the holder’s RETA cuota: they sit in different boxes on the activity map.

Remuneration to a spouse or to minor children who work in the activity may be deductible expenses if the requirements in article 30.2.2.ª of the IRPF Law are met (habitual and continuous work, cohabitation, employment contract, Social Security affiliation and pay not above market). Law 35/2006 on Personal Income Tax, article 30. If you operate as a corporate self-employed person with an administrator payroll, the cross-check between cuota, IRPF and payroll has its own treatment; do not solve it with this generic guide: see corporate self-employed Social Security, IRPF and payroll.

Rent, repairs, professionals, insurance and finance

Premises, co-working, leased or rented equipment, repairs and maintenance, fees of an accountant or other independent professionals, insurance premiums tied to the activity and finance costs linked to the activity appear in the external-services and finance map. AEAT, deductible expenses under direct estimation. A premises policy or a professional-liability policy is easy to explain. A personal policy of the holder does not become an activity cost just because you put it through the business bank account.

Amortization

Depreciation of affected assets is deducted through amortization charges. Under simplified, tangible fixed assets follow the special 1998 table; under normal, the general rules (including the table in article 12.1.a) of the Corporation Tax Law when it applies). AEAT, deductible expenses under direct estimation. The operating detail of the simplified table is in simplified direct estimation amortization table. Without affectation of the asset, there is no activity amortization to defend.

Other taxes (that are not IRPF itself)

Non-state taxes and surcharges, levies, fees and special contributions that are not passed on are deductible when they fall on the computed income, are not punitive and belong to the same period as the income. Examples include IAE and the IBI that corresponds to the activity. Criminal or administrative penalties, enforcement surcharges and the surcharge for a late return without prior demand are not deductible expenses. AEAT, other tax-deductible taxes. IRPF itself is not “deducted” as an activity expense: it is the tax you settle on the income.

The activity holder’s RETA contributions are included among the holder’s expenses when determining net yield. AEAT, Social Security or mutual society contributions of the holder; AEAT, expenses of the activity holder. That cuota lowers the activity yield. It is not the same mechanism as an employee’s Social Security contribution, which forms part of the deductible employment expenses under article 19. AEAT, deductible expenses under article 19.

Under the income-bracket contribution system, the chosen bases are provisional until regularization. If an additional amount becomes payable in the following year, that payment is treated as a higher deductible contribution expense in that following year; if a refund arises, it is treated as a lower expense (and any excess over the year’s cuotas, where applicable, as higher yield). AEAT, expenses of the activity holder.

As a general rule, contributions to mutual provident societies of the entrepreneur or professional themselves are not a deductible expense for determining the activity’s net yield, because they may reduce the general tax base under their own requirements and limits. Amounts paid to mutual societies that act as alternatives to RETA do count as a deductible expense for the part relating to contingencies covered by that special regime and within the limit of the maximum common-contingencies cuota for the year. AEAT, expenses of the activity holder; Law 35/2006 on Personal Income Tax, article 30.2.1.ª. An ordinary self-employed pension plan is, in most cases, treated as a base reduction, not as an activity-expense rubric.

If the same taxpayer has administrator remuneration and an economic activity, with a single RETA registration for pluriactivity, the AEAT allows a choice of where to place that single cuota: in employment net yield or in activity net yield. AEAT, expenses of the activity holder. That option does not turn the cuota into a generic article 19 expense; it is a specific placement rule for the same payment.

Partly affected home and supplies

When you use part of your habitual home for the activity, separate two blocks.

Ownership costs (amortization, IBI, community charges and similar) are deductible in proportion to the affected part of the home and the ownership percentage in the property. If you are a tenant, rent is prorated by the exclusively affected share. AEAT, rules for affecting assets; Law 35/2006 on Personal Income Tax, article 30.2.5.ª.

When the taxpayer partly affects their habitual home to the activity, supplies (water, gas, electricity, telephony and Internet) are deductible in the percentage obtained by applying 30% to the proportion between the square metres used for the activity and the total floor area, unless a higher or lower percentage is proved. AEAT, supplies; Law 35/2006 on Personal Income Tax, article 30.2.5.ª.b). The AEAT example is clear: 40 m² of 100 m² give a 40% floor-area share; 30% × 40% = 12%; on €5,000 of annual supplies, €600 is deductible. AEAT, supplies.

Costs of using a mobile telephony line are deductible to the extent that the line is used exclusively for carrying on the economic activity; acquisition of the handset itself, where applicable, goes through amortization. AEAT, supplies. Do not transplant here the VAT treatment of supplies in a mixed-use property: that analysis is another tax and is covered in tax-deductible business expenses in Spain.

Vehicles for IRPF: affectation, not the 50% VAT presumption

For IRPF, affected assets must be used for the purposes of the activity. As a general rule, assets used at the same time for the activity and for private needs are not treated as affected, unless private use is accessory and clearly irrelevant. That exception does not apply to passenger cars and their trailers, mopeds, motorcycles, aircraft or sports or recreational boats: those assets are treated as affected only when used exclusively for the purposes of the activity. AEAT, rules for affecting assets; IRPF Regulations, article 22.

There are listed exceptions where accessory and clearly irrelevant private use is allowed without losing affectation: mixed vehicles used for goods transport; vehicles used for passenger transport for consideration; vehicles used for driver or pilot training for consideration; vehicles used for professional journeys of sales representatives or commercial agents; or vehicles used for habitual onerous assignment of use. AEAT, rules for affecting assets.

The 50% VAT presumption for passenger cars does not transfer automatically to IRPF. The evidence, VAT and mixed-use chapter is in tax-deductible business expenses in Spain. Here the affectation rule is enough: without exclusivity (or without fitting a listed case), an ordinary passenger car does not justify amortization or activity expenses for IRPF as if it were a fully affected asset.

Holder subsistence during the activity

Taxpayers may deduct, when determining net yield under direct estimation, their own subsistence expenses if these requirements are met: they are expenses of the taxpayer themselves; they arise in carrying on the activity; they occur in restaurants and catering establishments; they are paid by electronic means; and they do not exceed the quantitative limits in article 9.A.3.a) of the IRPF Regulations for workers’ subsistence allowances. AEAT, taxpayer subsistence expenses; Law 35/2006 on Personal Income Tax, article 30.2.5.ª.c).

The limits published in the 2025 Income Tax manual are: in Spain, €53.34 per day with an overnight stay in a municipality other than the usual workplace and residence, and €26.67 per day without overnight stay; abroad, €91.35 per day and €48.08 per day respectively. The excess is not deductible. AEAT, taxpayer subsistence expenses; AEAT, expenses of the activity holder.

The fact that the cost falls on a working day does not by itself show it arose in carrying on the activity. The cross-reference to article 9 of the Regulations is limited to the maximum subsistence amounts: it does not automatically open deduction of lodging or copy the full employment subsistence regime. AEAT, expenses of the activity holder. Keep the supporting documents for the prescription period.

This does not go in (or it goes in through another door)

Several common confusions mix employee boxes with activity rubrics:

Deductible employment expenses (article 19 IRPF Law). Employee contributions, passive rights, trade unions, professional associations with a limit, legal defence with a limit and the “other expenses” concept (including the general €2,000 annual amount and its increases) determine employment net yield, not economic-activity yield. AEAT, deductible expenses under article 19.
Personal and family minimum and base reductions. They operate later, in the personal assessment; they are not “activity expenses” on the direct-estimation table.
Residual habitual-home deduction. It is a tax-credit deduction with its own transitional regime for home buyers, not an activity-expense rubric.
Pension plans and ordinary mutual societies of the holder. As a general rule they go to a reduction of the general tax base, not to an activity expense; the alternative-to-RETA mutual society exception has already been noted. AEAT, non-deductible expenses; AEAT, expenses of the activity holder.
Fines, penalties, enforcement surcharges and the surcharge for filing late. They are not tax-deductible expenses. AEAT, non-deductible expenses.
Donations and gifts, with the nuance that certain public-relations or promotional costs are not treated as gifts, although they remain subject to the 1% limit of the period’s net turnover. AEAT, non-deductible expenses.

If you are in modules, yield is not built by subtracting this map of real expenses: it uses signs, indexes or modules. The contrast is in direct estimation versus modules in Spain. The freelancer’s quarterly VAT and IRPF calendar is another operating layer: quarterly VAT and income tax for freelancers.

Decision criterion: activity or personal

Book the expense in the activity records when you can explain its link to earning income, you have supporting documents and a record entry, and it fits a direct-estimation rubric. Leave it out, or book only the affected share, when the use is personal, the passenger car fails the IRPF exclusivity test, an ordinary mutual society contribution belongs in a base reduction, or you are looking at article 19 boxes that belong to employees. AEAT, requirements for a deductible expense; AEAT, rules for affecting assets.

A practical sequence, without turning it into an official model:

Does the expense arise from the economic activity or from your private life or an employment payroll?
Is it in the activity record books or accounts, with allocation to the correct period?
Which AEAT map rubric does it belong to (holder, staff, supplies, amortization, and so on)?
Is there a special rule (30% supplies, vehicle exclusivity, subsistence limits, alternative mutual society)?
Is the real doubt about evidence? Then open the file with tax-deductible business expenses in Spain, rather than inflating the rubric.

The next useful step is to review the activity books and the breakdown that feeds modelo 130 and, later, the annual return. Hunting for the employee box in the Income Tax return will not help. Choosing normal or simplified affects amortization and the 5%, but it does not invent expenses that do not exist: normal or simplified direct estimation.

What to do now

List the expenses you are treating as “IRPF deductible” and mark which are activity costs and which are employment or personal.
Cross that list with the AEAT rubric map and with your record books or accounts.
Recalculate home (ownership versus supplies with the 30% rule), the holder’s RETA cuota and, if it applies, subsistence with limits and electronic payment.
Park the mixed-use passenger car until you confirm exclusivity or a listed case; do not copy the VAT percentage.
If the evidence file is weak, complete documentation before forcing the deduction.

This guide is limited to Spain’s common state IRPF territory and to activity expenses under direct estimation: it does not resolve objective estimation (modules), Corporation Tax, the Basque Country, Navarre, the Canary Islands with IGIC, Ceuta or Melilla; it does not turn a particular receipt into a deductible expense or replace your accountant’s engagement. AEAT, normal direct estimation; Law 35/2006 on Personal Income Tax.

Frequently asked questions

Are a self-employed person’s IRPF deductible expenses the same as an employee’s?

No. Under direct estimation, the net yield of the activity is gross income minus the deductible expenses of that activity. An employee applies, under employment income, the closed list in article 19 of the IRPF Law (contributions, trade unions, professional associations with limits, legal defence and the “other expenses” concept, among others). They are different boxes and different rules.

Yes. The holder’s RETA contributions are included among the activity holder’s expenses when determining net yield under direct estimation. Ordinary contributions to mutual provident societies of the entrepreneur or professional themselves do not, as a general rule, constitute an activity expense: they may reduce the general tax base if they meet the requirements. Only mutual societies that act as alternatives to RETA, for the part and within the limit set by the rules, enter as a deductible activity expense.

How do I deduct electricity, water and Internet if I work from home?

If you partly affect your habitual home to the activity, supplies (water, gas, electricity, telephony and Internet) are deducted by applying 30% to the proportion of square metres used for the activity over the total floor area, unless you prove a higher or lower percentage. Ownership costs (IBI, community charges, property depreciation and similar) are prorated by affected floor area and ownership percentage, without that 30% rule. A personal mobile line is not deducted automatically: the AEAT requires exclusive use for the activity.

Can I deduct work meals against the activity’s IRPF?

You can deduct the taxpayer’s own subsistence expenses when they arise in the course of the activity, in restaurants or catering establishments, are paid by electronic means and do not exceed the quantitative limits in article 9.A.3.a) of the IRPF Regulations (for example, €26.67 per day in Spain without overnight stay in a different municipality; €53.34 per day with an overnight stay). The fact that it is a working day is not enough on its own to show the expense belongs to the activity. Any amount above the limit is not deducted.

Is a mixed-use passenger car deductible for IRPF in the same way as for VAT?

Do not copy the 50% VAT presumption. For IRPF, passenger cars and similar assets are treated as affected only if used exclusively for the activity, except for listed cases (goods transport in mixed vehicles, passenger transport, driving schools, sales representatives or commercial agents, and habitual onerous assignment of use). Evidence and VAT analysis are in the guide on tax-deductible business expenses in Spain.

What should I do if I am unsure whether to book an expense in the activity or leave it as personal?

Review the activity books or accounts, not the employment-income boxes. Ask whether the expense is connected with the activity, recorded, allocated to the correct period and supported. If the answer is weak, treat it as personal or strengthen the file before including it. The next useful step is to check the file with your accountant against the activity rubric map.
