Mexico’s Tax Revenue Hits a Record in Pesos but Shrinks After Inflation
Economy
Key Facts
—The headline. Mexico’s tax revenue reached about 2.48 trillion pesos ($142 billion) in the first five months of 2026.
—The catch. Adjusted for inflation, that take actually fell about 1.4%, the first such drop for the period in years.
—The culprit. Income-tax collection slid about 5.8% in real terms as the economy stalled.
—The offset. Consumption taxes held up, with VAT bringing in about 703 billion pesos.
—Total income. Counting all sources, the federal government took in about 2.78 trillion pesos ($159 billion).
—Why it matters. Mexico is trying to fund its budget through enforcement, not new taxes, and the slowdown tests that.
The Mexico tax revenue figures look like a record on the surface. Underneath, they tell a more worrying story about a slowing economy.
The tax authority, the SAT, reported that federal tax collection reached about two point four eight trillion pesos in the first five months of 2026. In pesos, that is a fresh high.
The real picture is different. Once inflation is stripped out, that take fell by roughly one point four percent against the same stretch of 2025.
That is a notable break. It is the first real decline in tax revenue for this part of the year since 2012, a drop of 14 years, ending a long run of steady annual gains. However, our reporting has shown that this is the second consecutive month of real decline, following a 1.6% drop in the first four months of 2026, confirming a deepening trend rather than a one-off slip.
What is dragging Mexico tax revenue down
The weakness sits mostly in income tax. Collection from the levy known as ISR fell about five point eight percent in real terms, the sharpest drag on the total.
The cause is the wider economy. Mexico’s output barely grew in early 2026, with manufacturing and construction especially soft, and weaker corporate profits feed straight into lower income-tax receipts.
Consumption taxes cushioned the blow. Value-added tax brought in about seven hundred and three billion pesos, holding up as households kept spending even as industry cooled.
Excise duties also rose. Higher rates on fuel, tobacco and sugary drinks lifted that line, but the gains were not enough to offset the income-tax shortfall.
The miss shows up against the government’s own plan. Earlier in the year, tax collection ran below the target set in the federal revenue law, with income tax the largest gap.
Corporate filings tell the story in miniature. Average income-tax paid per company filing dropped sharply, a direct reflection of thinner profits across industry.
Why the numbers matter for the budget
Counting every source, the government took in about two point seven eight trillion pesos, roughly one hundred and fifty-nine billion dollars. That is a small nominal rise on last year.
The strategy behind the plan is what is under strain. President Claudia Sheinbaum has pledged to raise money through tighter enforcement and customs, not through new or higher taxes. Yet our reporting has shown that this enforcement-first model is already missing its targets: income-tax collection alone fell 55.5 billion pesos below the government’s own revenue law target earlier this year.
That approach depends on growth. When the economy stalls, enforcement gains struggle to keep pace, and the revenue math behind the budget gets harder.
For now, spending restraint has cushioned the hit. Tight control of outlays kept the fiscal deficit below the level officials had planned, even as revenue lagged.
The full-year goal still looks demanding. To hit its revenue target as a share of the economy, the government would need collection to accelerate sharply in the second half.
There is a trade cloud too. A review of the North American trade pact is under way, and its outcome will shape the export sector that underpins much of Mexico’s tax base.
For a foreign investor, the read is cautious. Mexico’s public finances are holding for now, but a soft economy and a trade review make the second half the real test.
One bright spot is prices. Inflation has eased toward the central bank’s target in mid-2026, which gives Banxico room to keep cutting rates and support a recovery.
Did Mexico tax revenue actually grow in 2026?
In pesos, yes: collection reached a record of about two point four eight trillion in the first five months. But adjusted for inflation it fell around one point four percent, the first real decline for that period in over a decade.
Why did income-tax collection fall?
Income tax, known as ISR, dropped about five point eight percent in real terms because the economy barely grew. Weak manufacturing and construction lowered corporate profits, which directly reduced the income-tax take.
What does this mean for Mexico’s budget?
The government aims to fund spending through better enforcement rather than new taxes, a plan that leans on economic growth. A stalling economy and an uncertain trade review make hitting full-year revenue targets harder.
