Your tax regime is a suit: how not to run in one three sizes too costly

Your tax regime isn't a registration formality: it's the variable that defines what rate you pay, what you deduct and how much administrative burden you drag along. And like suits, the problem is almost never that your size doesn't exist — it's that you signed up (or were signed up) for the first one available and never got measured again. Entrepreneurs billing millions as individuals at 35% with the 30% corporate option on the table; landlords in the business-activity regime with no idea the blind deduction exists; farmers taxed under the general regime with the exempt primary-sector regime right in front of them. The cost of the wrong size is paid every month.

The full closet, in one pass

• General regime for legal entities: the universal work suit — 30% on profit, broad deductions, the door to group structures (holding, wealth, operating companies). Its cost: full accounting and compliance discipline.
• RESICO (simplified regime, for individuals and companies): the system's preferential rates — 1% to 2.5% on income collected for individuals up to $3.5M, and for companies a cash-flow mechanic with the normal schedule. Powerful and fragile: the grounds for expulsion are easy to trip.
• Individuals with business and professional activity: flexible, cash-basis deduction (purchases are deducted when paid — a real advantage in inventory businesses), but with a progressive schedule up to 35%: above a certain profit, the 30% company plus the dividend architecture usually beats it.
• Leasing: landlords' favorite regime thanks to the 35% blind deduction (deducción ciega — a flat deduction with no receipts) plus property tax, without documenting a single peso — it deserves its own analysis against real deductions.
• Primary sector (AGAPES — agriculture, livestock, fishing and forestry): exemptions measured in UMA (the daily reference unit) and ISR reductions that make it one of the most favored regimes in the system — when the activity is genuine; the "paper farmer" is a 69-B classic.
• Wages, asimilados a salarios (salary-assimilated income), dividends, interest: the regimes of the individual's personal wealth — which aren't so much chosen as combined: a well-designed owner's compensation uses several at once.

The signs you're wearing the wrong size

You pay a 35% marginal rate as an individual on profit that could support a company. You hold large inventories in a company with tight cash flow (cost of goods sold defers your deduction — there's analysis to do). You rent out property while documenting expenses below 35% of your income (the blind deduction hands you the difference). Your activity is primary and you're taxed under the general regime. You bill as salary-assimilated income an activity that is really business (wrong size and risk). You grew and your structure is still the one from year one — the debut suit on a company that now bills twenty times more.
