Tax Services
Multi-State Tax Compliance Without the Exposure.
Best Practicify's SALT practice delivers state income tax, franchise tax, and sales tax compliance for businesses operating across multiple states — with specialized expertise in eCommerce economic nexus and the post-Wayfair compliance landscape.
What We Deliver
Best Practicify's SALT Capabilities.
Economic Nexus Analysis & Registration
Analysis of sales volume and transaction counts across all 50 states — identifying where collection obligations exist, registering in states where nexus has been triggered, and documenting the analysis for future reference.
Sales Tax Compliance & Filing
State sales tax return preparation and filing — monthly, quarterly, and annual — across all registered states. Returns prepared from actual sales data, not estimates, and filed on time with remittance.
TaxJar & Avalara Implementation
Sales tax automation platform setup — nexus monitoring, real-time rate calculation, automated return preparation, and filing. Marketplace facilitator analysis confirming which states Amazon, Shopify, and Walmart collect on your behalf.
Voluntary Disclosure Agreements
Resolving historical sales tax and income tax non-compliance before states initiate contact — VDA negotiations that limit lookback periods and waive penalties for businesses coming into compliance proactively.
State Income Tax & Franchise Tax
Multi-state income tax returns with apportionment analysis, nexus determination for income tax purposes, and franchise tax compliance for states where it applies regardless of income.
State Audit Defense
Audit response, documentation preparation, and representation for state sales tax and income tax audits — direct CPA involvement for businesses facing state examination.
