Question 1

How is net salary calculated from gross?

Accepted Answer

Net salary is calculated by subtracting from gross salary the income tax withholdings (which vary according to your personal situation and autonomous community) and Social Security contributions (6.50% in 2026, includes MEI 0.15%). Our calculator applies these deductions automatically according to the brackets in force in 2026.

Question 2

What is MEI and how does it affect me in 2026?

Accepted Answer

The MEI (Intergenerational Equity Mechanism) is an additional Social Security contribution of 0.15% in 2026 created to ensure the sustainability of the pension system. With a salary of €30,000, this means about €109 per year (€9/month). MEI increases progressively each year until reaching 0.20% in 2029. Read more about MEI 2026 here.

Question 3

Why does income tax vary by autonomous community?

Accepted Answer

Each autonomous community has authority over the regional income tax bracket, which represents approximately 50% of the tax. Communities like Madrid have lower rates, while others like Catalonia or Andalusia apply higher rates in high brackets. This difference can mean several thousand euros per year with the same gross salary.

Question 4

What's the difference between 12, 14 and 15 payments?

Accepted Answer

The number of payments affects salary distribution throughout the year. With 14 payments (most common), you receive two extra payments (summer and Christmas). With 12 payments, your monthly salary is higher because extras are prorated. With 15 payments, some companies split one extra into two. The annual gross salary is the same, only the distribution changes.

Question 5

Is this calculator's result accurate?

Accepted Answer

Yes, our calculator has 95% accuracy for standard profiles (single without children, no disability). Calculations are based on official 2026 income tax and Social Security regulations (includes MEI 0.15%). For special situations (marriage, children, disability, mortgage), use the advanced calculator that includes all these factors.

Question 6

What are Social Security contributions?

Accepted Answer

They are mandatory contributions deducted from your payslip to fund the social protection system (pensions, healthcare, unemployment). The employee pays 6.50% in 2026 of their gross salary (includes MEI 0.15%), while the company pays about 30%. This percentage applies to contribution bases, which have maximum and minimum caps.

Question 7

How do children affect net salary?

Accepted Answer

Having children reduces income tax withholdings because they increase the personal and family minimums that apply. This means the Tax Agency withholds less each month from your payslip, increasing your net salary. The impact depends on the number of children and your income level, but can mean €50-200/month more in your net.

Question 8

What's better, Madrid or Barcelona in tax terms?

Accepted Answer

Madrid has lower income tax in all brackets, especially for medium-high salaries. For a €40,000 salary, the difference is approximately €732/year more net in Madrid. However, Barcelona may compensate with better public services. Check our Madrid vs Barcelona comparison guide for more details.

Question 9

Do freelancers have the same calculation as employees?

Accepted Answer

No, freelancers have a different system. They pay a monthly Social Security fee (from €230 on the flat rate to €500+) and then make quarterly income tax declarations. Net depends on their income, deductible expenses and chosen contribution base. Check our freelancer guide.

Question 10

Can I legally reduce my income tax?

Accepted Answer

Yes, there are several legal ways: pension plans (reduce taxable base up to €1,500/year), NGO donations (80% deduction on first €150), investment in new companies (50% deduction up to €60,000), or adjust your withholdings if you have children, mortgage or disability. These strategies can save you hundreds or thousands of euros per year.

Question 11

What if my payslip doesn't match the calculation?

Accepted Answer

Small differences (±€50) are normal due to rounding, arrears or additional items (per diems, transport allowance). If the difference is large, verify: 1) That your company applies the correct income tax bracket according to your family situation, 2) That contribution bases are correct, 3) That there are no additional deductions (advances, garnishments, etc.). Consult your HR department or an advisor if the doubt persists.
