The DGII doesn't wait. Neither do we.
Strategic tax planning, fiscal defense, and full compliance with your obligations. With the advantage of a team led by someone who is both a CPA and an Attorney — because taxes aren't just numbers, they're law.

Important: Penalties for tax non-compliance in the DR can reach 30% of the tax owed, plus monthly surcharges of 2%. Prevention always costs less than the penalty.

Tax Retainer
Forms, returns, payments, and DGII representation — all handled so you can focus on your business.
Tax Returns

How We Work
From first contact to ongoing compliance — a clear process, no surprises.
Tax Diagnostic
We review your tax history, filed returns, payments made, and potential contingencies — identifying exactly where your risk lies and your true starting point.
Personalized Strategy
Based on the diagnostic, we design an action plan: what to correct, what to optimize, and how to structure your operations to pay the right amount while staying in full compliance.
Implementation
We execute the plan: file returns, process adjustments, represent you before the DGII if needed, and install controls so your company stops accumulating tax contingencies.
Ongoing Monitoring
The tax environment changes. We monitor DGII rulings, regulatory updates, and filing deadlines. You are always one step ahead — anticipating, not reacting.
Why Choose Effort for Your Taxes
We are not a forms-filing shop — we are your strategic tax partner.
CPA + Attorney in one team
Most tax disputes have a legal dimension a CPA alone cannot resolve. And an attorney without accounting training doesn't understand the numbers. We integrate both disciplines seamlessly.
DGII expertise — from both sides
We know how the tax authority thinks because we understand the law it applies. That perspective is your advantage when negotiating, defending, and planning.
Real reduction in your tax burden
We don't just comply — we optimize. Our clients pay what the law requires, not a peso more. The difference can be substantial at the close of each fiscal year.
Zero penalties for non-compliance
With our tax retainer, no deadline passes unattended. We manage your tax calendar with the same precision you apply to running your business.
