Introducing Tax Account Management

Introducing Tax Account Management

Today we are announcing Mosey Tax Account Management—the best way to register, resolve agency notices, and monitor for issues across all 1,200+ state and local tax accounts.

We designed Tax Account Management for busy finance and payroll teams struggling with penalties and distractions from taxes in 50 states and thousands of localities. No more missed registrations that cause back taxes. No more missed tax rate changes that lead to underpayment penalties. Last but not least, no more toil from dealing with letters from state agencies.

Zero payroll tax penalties

Multi-state businesses need more help and expertise to navigate taxes than ever before. An all too common experience is getting surprised by penalties and fines, sometimes for taxes businesses weren’t even aware of. Indeed, 1 in 3 notices from tax agencies analyzed by Mosey were a penalty or fine for underpayment.

Manage and resolve notices from payroll agencies

That’s why we built Mosey Tax Account Management—to put an end to tax penalties by helping finance and payroll teams take control of the full lifecycle of all 1,200+ different state and local tax accounts in the United States.

Mosey Tax Account Management automates the end-to-end lifecycle of all tax accounts:

  1. Register and open mandatory tax accounts
  2. Maintain accounts (tax rates, notices, portal changes)
  3. Close accounts when they are no longer needed

Zero Payroll Penalties.

Fast and accurate registration

Tax Account Management builds on 5 years of experience and thousands of registrations in nearly every jurisdiction in the US. Our rigorous approach to registration means every application is reviewed by humans and customers enjoy registration with high accuracy (99.9% over the last two quarters).

Registration with Mosey is more than what you may have experienced with other providers:

  • Never deal with agencies directly yourself—our team gets in touch with agencies so you don’t need to sit on hold for hours
  • Only the minimum information collected to register—never get asked for the same information twice and no spreadsheets
  • Automated TPA requests for every major payroll provider to prevent misconfiguration issues with payroll
  • Automatically connect newly registered tax accounts to Mosey to receive notices and securely share logins

Centralized Oversight for 1,200+ Tax Accounts

As a rule of thumb, a business has 2 to 3 tax accounts for every state they operate in (e.g. withholding, unemployment insurance, PFML). If the list of states includes PA, OH, and KY, you can tack on even more as these states have extensive city and county level taxes.

When you’re dealing with dozens of tax accounts, the issues pile up exponentially. Without automated tools, even simple things like maintaining a login to each portal, leads to constant manual work. Worse, it can feel like a never ending game of whack-a-mole with penalties, rate changes, claims, and account upgrades.

Centralize account management view

Mosey centralizes tax accounts into one system so busy payroll and finance teams don’t need to worry about missing anything.

Expert help to resolve tax issues

Things can go wrong even when payroll and finance teams have the best intentions.

When a tax problem is detected or a notice from an agency is received, Mosey is there to resolve it. If it can’t be resolved automatically, our compliance experts work with your team and the state agency to address it.

AI mail summary and notice resolution

What about existing tax accounts you’ve already set up?

You can bring all of your existing tax accounts and connect them to Mosey. During onboarding, our team runs payroll diagnostics to detect existing issues. We work with your team to address issues, recover and close down accounts, so you start from a clean slate.

Tax account closures

When your business no longer has employees in a location, you can identify which tax accounts can be closed and then close them properly with Mosey. Every agency has different procedures and the best way to avoid trailing tax penalties and liabilities is to have Mosey shut it down for you.

  • Properly exit from a jurisdiction, closing the right tax accounts at the right time
  • Avoid trailing tax liabilities and penalties
  • Support for mergers and acquisitions
