Adjust your taxes for inflation: What is deflating and how does it impact your investment strategy?

The Current Context: Why We Talk About Deflation

2022 marked a turning point in the Western economy. Central banks have raised interest rates unprecedentedly in decades to combat record inflation. In Spain, this inflation reached 6.8% in November 2022, meaning a clear erosion of the purchasing power of citizens and businesses.

In this scenario, a term that we hear more and more in political and economic debates emerges: deflating. But what does it really mean, and why should it matter to you as an investor?

Understanding the Deflator: From Theory to Reality

The deflator is, in essence, a mathematical adjustment that allows for comparing economic values over time by eliminating the “noise” caused by inflation or deflation. Imagine comparing your income from 2021 with that of 2022 without considering that prices increased by 10%: you would be measuring with different variables.

For example, if a country produced goods and services worth 10 million euros in year 1 and then 12 million in year 2, it might seem that it grew by 20%. But if prices rose 10% during that period, the actual growth figure is much lower: just 10%. The deflator corrects precisely that, allowing us to distinguish between nominal growth (inflated by prices) and real growth (true economic expansion).

This adjustment is fundamental in economics to evaluate wages, business sales, gross domestic product (GDP), and, of course, personal tax brackets.

Deflating Income Tax (IRPF): The Fiscal Measure Under Debate

In Spain, various autonomous governments are currently discussing a specific measure: adjusting the brackets of the Personal Income Tax (IRPF) according to inflation.

What does this mean? The IRPF is a progressive tax that taxes the income of residents in Spain. Its brackets are adjusted so that when your nominal salary (in numbers) increases, you don’t automatically end up in a higher tax bracket with a disproportionate tax burden.

Without deflation adjustment, something unfair happens: you receive a 5% salary increase, but since the brackets are not adjusted for inflation, you end up paying proportionally more taxes, losing purchasing power despite the increase.

When IRPF is deflated, the brackets are updated considering both the Consumer Price Index (CPI) and salary variation, ensuring you maintain your real purchasing capacity.

In the United States, France, Nordic countries, and even Germany (every two years), this adjustment is already done regularly. In Spain, at the national level, it hasn’t been done since 2008, although some autonomous communities have announced it for upcoming fiscal years.

Benefit or Illusion? Analyzing Advantages and Disadvantages

Arguments in favor:

• Protects the purchasing power of working families
• Prevents inflation from generating a “hidden tax increase”
• Maintains fairness in the tax system

Criticisms:

• Disproportionately benefits higher incomes due to the progressive tax
• Potentially reduces fiscal revenues to fund public services
• Some economists argue that recovering purchasing power can fuel more demand and, with it, more inflation
• The actual financial impact on the average taxpayer is modest (hundreds of euros annually)

How to Adapt Your Investment Strategy in Times of Inflation and High Rates

The reality is that deflating the IRPF can leave some extra money in your hands, but the real battle is fought in how you invest that capital in an environment of inflation and restrictive fiscal policies.

Commodities and gold as a refuge

Gold has historically acted as a safe haven during times of economic uncertainty. When the value of money falls and interest rates rise, investors seek it because it is not linked to any specific economy. In the long term, gold tends to preserve or increase its value, although in the short and medium term, it can be very volatile.

Stocks: selectivity is key

2022 made it clear that inflation and high rates penalize the stock market in general. Highly indebted companies see their financial costs increase, pressuring profits and valuations.

However, not all stocks suffer equally. Energy companies hit record highs this year, while the tech sector plummeted. Defensive sectors that cover basic needs tend to perform better.

For long-term investors, recessions can present opportunities: depressed stock prices allow buying quality assets at a discount, with potential for historic recovery.

Currencies: high risk, potential differential

The forex (foreign exchange) market can be attractive in inflation because exchange rates are affected by inflation differentials between countries. A currency with very high inflation tends to depreciate against more stable currencies.

But beware: forex is highly volatile, especially with leverage. It is not recommended for inexperienced investors.

The winning strategy: diversification

In any inflationary or recessionary context, diversification is your best ally:

• Combine low-risk assets (Treasury bonds) with growth potential (select stocks)
• Include assets that historically gain with inflation (real estate, commodities)
• Consider the fiscal impact of each investment, as gains and yields are taxed in IRPF
• Spread risk across sectors and geographies

Final Reflection: Complete Context for Your Decisions

Deflating the IRPF can marginally improve your tax situation, but it is not a panacea. The true impact on your wealth will depend on how you structure your investments in the face of inflation, interest rates, and recession risk.

The key is to act with information: understand what a deflator is, how it affects your taxes, and adjust your investment portfolio according to your goals and time horizon. Financial education, in times of economic uncertainty, is your best deflator.
