# Puerto Rico's CPAs Put a Flat Corporate Rate and a VAT on the Table — and Show Who Pays for the Status Quo

A 183-page CCPA study finds a 33-point spread between decree holders and regular corporations, a middle class whose rates quadruple between $30,000 and $100,000, and 42.7% of sales tax paid by businesses themselves.

## What the numbers say

Puerto Rico's tax code charges some companies as little as 4% and others as much as 37.5% on the same profits, and the Puerto Rico Society of Certified Public Accountants (CCPA) says that spread is the reason investment flows by tax treatment instead of productivity. On Tuesday the CCPA and its foundation presented a 183-page structural study of the tax system, prepared by Abexus Analytics and economist Edwin Ríos, that puts a flat corporate rate below the U.S. level on the table — competitive with Ireland's 12.5% and Singapore's 17% — and recommends converting the IVU into a value-added tax.[^1][^2]

The arithmetic behind the diagnosis is stark. A company that crosses $100,000 in gross income can see its tax bill jump from roughly $6,000 to $10,000 — one additional dollar of income costing about $4,000 in tax.[^3] The code has been amended 152 times between 1994 and 2025, 98 of them since 2011, and property tax assessments still run on values derived from 1957.[^4][^5]

## Who carries the load

The study's sharpest finding is about the middle. Salaried workers earning $30,000 to $100,000 — the group defined as the island's middle class — pay more of their salary in tax, pay more sales tax, receive fewer credits and incentives than any other group, and will shrink the most as the population declines.[^6][^7] Effective rates quadruple between $30,000 and $100,000 of income, from 2.9% to 12.6%, while earnings above $200,000 face a nearly flat 19% to 20%. Fixed deductions are not indexed to inflation: the $2,500 deduction per dependent would be $3,762 today if it had kept pace.[^8]

The sales tax compounds the pressure. An estimated $1.72 billion of the $4.04 billion collected in 2025 — 42.7% — came from purchases companies make to operate, tax that accumulates through the supply chain and lands in consumer prices or smaller margins.[^9]

## The so-what for businesses and the Treasury

For the corner store, the pharmacy and the local manufacturer without a decree, the study's order of priorities is concrete: tax profits at one rate, stop taxing inputs and inventory, and judge every incentive by the new investment it brings.[^1] The inventory and municipal license taxes fall hardest on small, low-margin firms — and the inventory tax pushes merchants to stock less than is prudent, which leaves the island more vulnerable in a supply disruption.

The counterweight is real and the authors do not hide it: a single rate helps the retailer paying 37.5% but raises the bill for decree holders — including the manufacturers and hotels driving what growth the island has — and any revenue-losing change must satisfy the Oversight Board's offset requirement. The study deliberately offers no cost estimates because the data needed for the simulations are not public. That is the actionable ask hiding in the diagnosis: Treasury publishing the data that would let reform be scored before it is argued.[^1]

With the economy effectively stalled — flat payroll employment since 2024 and fiscal 2027 forecasts ranging from a 1.4% GNP contraction to 0.3% GDP growth — the study's projection that current demographic trends would erase about 213,000 jobs and $843 million a year in income-tax and IVU collections by 2045 is the fiscal base under all of it.[^7]
