Federal and State Tax Compliance & Consulting

We help companies, business owners, and multi-jurisdictional groups maintain a strong tax position—meeting U.S. federal and state requirements with precision while improving efficiency and cash flow.

How we work—and what you receive

Our team combines Big-Four-level technical depth with the access and responsiveness of a boutique practice. Using tested methodologies, we review accounting and tax data, apply compliance controls, prepare projections, and advise on strategic decisions that directly affect cash flow and overall tax burden.

We support both established companies and new entrants into the U.S. market, integrating accounting, tax consulting, and representation before federal and state authorities.

Corporate and multi-entity tax preparation

Federal and state income tax returns for C corporations, S corporations, partnerships, and LLCs, prepared in line with current rules and the operational profile of each entity.

State and local tax compliance

State-by-state obligation reviews, nexus analysis, registrations, sales and use tax, franchise tax, and other local taxes—plus planning to avoid unnecessary double taxation and unpleasant surprises from state audits.

Strategic tax planning

Annual and multi-year tax strategies that align accounting and financial decisions with profitability, expansion, and capital allocation goals.

M&A tax advisory

Tax due diligence, deal structuring, step-up and loss utilization analysis, and post-acquisition compliance to minimize contingencies and capture available tax efficiencies.

Mitigation strategies and future planning

Review of existing ownership structures, assessment of potential restructurings, and intergenerational planning to reduce estate tax exposure in future successions and facilitate orderly transfers to the next generation.

Individual tax and planning for high-income earners

Personalized support for owners, partners, and executives with complex income streams; optimization of credits and deductions, coordination with business structures, and integrated estate and succession planning.

IRS and state representation

Support during federal and state audits, payment arrangements, amended returns, and voluntary disclosure programs—backed by technical analysis and experienced advocacy.

Federal, state, and local tax consulting

Ongoing advisory across corporate income tax, franchise tax, payroll tax, property tax, and excise taxes, as well as planning for reforms, new regulations, and emerging reporting requirements.

How we approach federal and state tax planning and compliance

Every business faces a unique web of tax obligations that varies by structure, industry, and location. At Guillen Pujol CPAs, we look at your situation as a whole—business model, legal structure, income mix, and multistate footprint—to identify optimization opportunities and reinforce compliance.
We design tailored tax strategies that integrate federal, state, and local taxes, always aligned with your economic reality and growth plans.

Frequently Asked Questions

What is the difference between federal and state taxes in the U.S.?

Federal taxes apply nationwide and are administered by the IRS. State and local taxes are imposed by each jurisdiction and can differ significantly in rates, bases, and compliance rules.

What are the benefits of working with one firm for both federal and state taxes?

A unified view helps avoid duplicated tax, leverage credits and deductions consistently, and keep federal, state, and local filings aligned. That reduces risk and improves medium- and long-term planning.

Do you work with both businesses and individuals?

Yes. We provide comprehensive services for corporations, partnerships, LLCs, and individuals with complex structures and income streams—especially business owners and high-income earners.

How do you help during IRS or state audits?

We represent you directly before the IRS and state agencies, prepare supporting documentation, analyze proposed adjustments, and negotiate resolutions that protect your financial position and cash flow.

What kind of planning do you recommend for multistate businesses?

A centralized compliance calendar, annual nexus reviews, coordination with local advisers where appropriate, and integrating tax impact into your expansion decisions before entering a new state.
