Multi-State Business Tax Compliance
Identify your state filing obligations and prepare the agreed business tax returns.
Online service across all 50 states

What this service is
Once a business has employees, property, or significant sales in more than one state, it may owe income or franchise tax in each of those states, and each state uses its own rules to decide how much of your profit it can tax. We determine where you have filing obligations (nexus), calculate how income is apportioned among those states, register you in the right order, prepare the state returns every year, and evaluate pass-through entity tax elections that can reduce owners' federal tax.
Forms & documents involved
What we actually do
Run a nexus study
Map where you have employees, property, sales, and remote workers, and compare that activity with each state's filing thresholds.
Calculate apportionment
Apply each state's sales-factor or multi-factor formula to determine the share of income each state can tax.
Sequence registrations
Register in new states and, where past-due exposure exists, evaluate voluntary disclosure agreements to limit penalties.
Prepare state income and franchise returns
File corporate, partnership, composite, and nonresident withholding returns in every required state.
Evaluate PTET elections
Model whether electing a state pass-through entity tax reduces owners' combined federal and state tax.
Track local taxes
Cover city and local business taxes where they apply, such as the New York City UBT and general corporation tax.
