Understanding State IRA Withholding Requirements

IRA withholding remitting, reporting and reconciling can be difficult for organizations to manage at a federal level, but it gets even more complicated when you add states to the mix. Each state has their own remitting and reporting frequencies, thresholds, requirements and penalty structures. Because of this, it can be hard to determine if and when state withholding is required on a state-by-state basis.

This map breaks down where IRA withholding remitting and reporting is mandatory, verses being voluntary or not required, on a state-by-state basis to help organizations understand their IRA state withholding requirements.


Centralizing and automating manual withholding processes has allowed organizations to improve operational efficiency by up to 92% allowing resources to focus on business critical tasks while mitigating process, compliance and security risk. Find out how Sovos can help.

Infographic: State 1099 Reporting Deadlines

By far, the biggest challenge facing organizations during 1099 reporting season this year was state reporting. With states tightening deadlines and multiple jurisdictions and reporting thresholds to deal with, Sovos customers found state reporting more complex than any other element of reporting season.

This updated infographic shows why. The map shows 1099 reporting deadlines by earliest deadline per state. In just a few years, the vast majority of 1099 first deadlines have shifted from March to January. Combine that shift with changing thresholds for 1099-K forms and other state-specific policies, and it is clear why state reporting has become such a challenge and will likely continue to be.


With reporting periods shrinking, organizations need to centralize and automate reporting processes in order to maximize efficiency, ensure compliance and avoid financial penalties.

Brazil: Electronic Invoicing and Reporting Requirements

In 2008, Brazil adopted a clearance electronic invoicing model in which the country’s tax authority must receive and clear an invoice before a supplier can issue it to a payer. More than a decade later, the Brazilian tax administration’s digitization has evolved so much that other tax administrations call Brazil the Google of fiscal goods. 

Current regulations include electronic invoices for: supplies of goods (NF-e), services (NFS-e), transport services (CT-e), freight (MDF-e), SPED, REINF and, more recently, for the supply of electricity (NF3e). 

This document provides an overview of the mandates and regulations in Brazil.

Mexico: Electronic Invoicing and Reporting Requirements

Mexico is a pioneer in electronic invoicing and VAT enforcement, having begun its digitization journey in 2010. Today, Mexico has one of the most technologically advanced tax administrations in the world. Companies unaware of or unprepared for Mexican e-invoicing mandates could face significant fines and penalties, along with supply-chain disruptions and cash-flow issues. This document provides an overview of mandates and regulations in Mexico.

Why Partner with a Certified Service Provider (CSP) for Sales Tax Administration

Certified Service Providers (CSPs) allow businesses to outsource most sales tax administration responsibilities, making it easier to comply with the laws of a given jurisdiction.

Choosing a CSP to manage your sales tax filings reduces the burden of managing end-to-end sales tax compliance while reducing organizational liability during the tax calculation process.

Complying with statutory reporting and state filing requirements is complex and involves several time-consuming tasks.

  • educational seminars

Streamlined Sales Tax Volunteer Seller Assessment


Six Questions to Assess your Volunteer Seller Status

This assessment is designed to help you determine whether you qualify for Volunteer Seller Status, which reduces your sales tax risk, burden and costs, in one or more of the 24 Streamlined Sales Tax (SST) states.

Qualifying as a Volunteer Seller allows you to benefit from reduced risk, burden, and cost when you partner with Sovos as your Certified Service Provider (CSP) for sales tax compliance. This partnership enables you to outsource most administrative compliance processes, saving time while maintaining confidence in the accuracy of your sales tax data. 

The below legal definitions should be referenced when utilizing this assessment.

Six Questions to Assess your Volunteer Seller Status

In answering these questions, remember that a company’s status as a “Volunteer Seller” is evaluated on a state-by-state basis, meaning your inability to qualify in State A (e.g. Kentucky) does not impact your ability to qualify in State B (e.g. Rhode Island). As such, consider each of the Streamlined Sales Tax states separately as you answer the following questions.


What is the legal definition of Property?

  • “Property” is the Average Value of the Seller’s real property and tangible personal property owned or rented by the Seller.
  • Property owned by the Seller is valued at its original cost basis.
  • Property rented by the Seller is valued at eight times the net annual rental rate.
  • Net annual rental rate is the annual rental rate paid by the Seller less any annual rental rate received by the Seller from sub-rentals.
  • The “Average Value” of Property shall be determined by averaging the values at the beginning and end of the twelve (12) month period immediately preceding the date of registration with the Streamlined State.

What is the legal definition of Payroll?

  • “Payroll” is the total amount paid by the Seller for Compensation during the twelve (12) month period immediately preceding the date of registration with the Streamlined State.
  • “Compensation” means wages, salaries, commissions and any other form of remuneration paid to employees and defined as gross income under Internal Revenue Code §61.
  • Compensation is paid in a Streamlined State if (1) the individual’s service is performed entirely within the Streamlined State, (2) the individual’s service is performed both within and outside the Streamlined State, but the service performed outside the Streamlined State is incidental to the individual’s service within the Streamlined State, or
  • (3) some of the service is performed in the Streamlined State and (a) the base of operations, or if there is no base of operations, the place from which the service is directed or controlled, is in the Streamlined State, or (b) the base of operations or the place from which the service is directed or controlled is not in any state in which some part of the service is performed, but the individual’s residence is in the Streamlined State
