Multi-State. Multi-Layered. Fully Managed.

Sales tax laws are no longer simple or uniform—and for growing businesses, managing state and local tax compliance has become a significant administrative and financial challenge. At A3M Partners, we take the complexity out of compliance by offering full-service Sales Tax & Other Tax Management tailored to your business’s geographic and operational footprint.

Whether you’re operating in one state or selling across the country, our team ensures you’re registered correctly, filing on time, and maintaining complete audit readiness—all without pulling your focus from running your business.

Why Sales Tax & Miscellaneous Compliance Is Critical

Sales tax is not just about collecting a flat percentage—it’s about knowing:

  • Which states and jurisdictions you have economic or physical nexus in

  • What products or services are taxable vs. exempt

  • When to register, file, and remit to state and local authorities

  • How to handle rate changes, penalty risks, and audits

As e-commerce, service-based businesses, and remote workforces expand, state and local taxing authorities are becoming more aggressive—and less forgiving. Failing to stay compliant can result in:

  • Penalties and back taxes

  • State audits

  • Personal liability for business owners in some states

  • Delays in licensing, expansion, or funding

We help you stay ahead of compliance issues before they become costly problems.

What We Deliver

A3M Partners provides comprehensive state and local tax compliance services, including registration, filing, advisory, and audit support. We customize our approach based on your industry, revenue streams, and state exposure.

Whether you’re a SaaS provider, retailer, service firm, or multi-location business, we help you untangle obligations across:

  • Sales & Use Tax
  • Franchise Tax
  • Excise Tax
  • Gross Receipts Tax
  • Local Business and Occupational Taxes

We manage the registrations, returns, and correspondence—so you don’t have to.

Our Sales Tax & Miscellaneous Compliance Package Includes:

Multi-State Sales Tax Registration

We determine where your business has nexus—physical or economic—and ensure that you’re registered correctly in each applicable jurisdiction.

This includes:

  • Evaluating annual revenue and transaction thresholds
  • Registering for sales tax IDs in each state
  • Handling local jurisdiction registrations (counties, cities, parishes)
  • Maintaining valid reseller and exemption certificates
  • Coordinating with tax automation platforms (e.g., Avalara, TaxJar) if applicable

We keep your business legally registered wherever you have tax obligations—without over-registering where you don’t.

Sales Tax Return Filing & Remittance

Once you’re registered, we take over all return preparation and filing responsibilities. Depending on your state and volume, we support:

  • Monthly, quarterly, or annual filings
  • Payment remittance directly or via connected accounting platforms
  • Reconciliation with your internal books or POS/e-commerce system
  • Filing of zero-dollar returns when required to maintain compliance

We ensure filings are timely, accurate, and penalty-free, even if you operate in 20+ states.

Nexus Analysis & Compliance Planning

Nexus rules are evolving rapidly—especially with remote employees and digital products. We monitor your activity to determine:

  • Which new states you may trigger nexus in
  • When registration becomes mandatory
  • When to deregister in inactive states
  • Where you can legally avoid sales tax through structure or exemption

We conduct annual and mid-year nexus reviews to keep your compliance footprint current and lean.

Miscellaneous State & Local Tax Support

Beyond sales tax, many businesses face additional tax obligations depending on where and how they operate. We support compliance for:

  • State Franchise Tax (e.g., Texas, Delaware, California)
  • Gross Receipts Tax (e.g., Nevada, Ohio, Washington)
  • Excise Tax on specific products or services
  • Business License Tax or B&O Tax at the city/county level
  • Use Tax self-assessments and remittance

Our team ensures you’re filing everything you should—no more, no less.

Audit Preparation & State Correspondence

If you’re selected for a state audit—or receive inquiries about missing returns, certificates, or nexus status—we’re here to help.

We provide:

  • Complete audit file preparation and documentation
  • Responses to notices and letters from tax authorities
  • Certificate management and exemption tracking
  • Support through payment plans or penalty abatement processes
  • Representation during audit procedures, if needed

We reduce audit risk through proactive compliance — and have your back if one comes.
