Invoicing and Tax regulation in USA

The United States is progressively advancing its transactional systems by increasingly adopting electronic invoicing across various sectors. Although e-invoicing is optional for federal institutions and B2B, B2C, or B2G transactions, many U.S. federal agencies and private companies have implemented e-invoicing to streamline operations and boost efficiency. By automating portions of the accounts payable process, e-invoicing improves efficiency, reduces processing time, and enhances accuracy. Compared to traditional paper-based invoicing, e-invoicing also offers significant cost savings and environmental benefits by eliminating the inefficiencies and high costs associated with manual paper processes, while also significantly reducing manual errors, which are particularly common in tax reporting. In the U.S., where tax rates and regulations can vary widely across different states, minimizing errors is crucial to avoid increased fiscal liabilities and penalties.

Invoicing Regulations in the United States

Invoicing regulations in the United States do not fall under a single regulatory body but are influenced by Internal Revenue Service (IRS) guidelines, state laws, and specific industry standards. There are no federal mandates specifying when invoices must be issued, but rather invoices are issued based on the terms agreed upon between businesses and their customers. The most common are:

  • Upon Delivery: Of goods or completion of services;
  • Credit Terms: Businesses may offer credit terms (for example: net 30 days); meaning the invoice is issued at the time of sale, but payment is due within the specified period;
  • Recurring Billing: For ongoing services, invoices may be issued on a recurring basis.
  • There are also no specific thresholds requiring different levels of detail on invoices as seen in some other countries. The choice of how detailed an invoice needs to be generally depends on the business’s internal requirements, customer needs, and any relevant industry standards. However, for tax purposes, the IRS requires that businesses maintain accurate records, which include invoices, to support taxable income and deductible expenses.

    Regardless of the level of detail, invoices should include several basic elements:

  • Seller Information: Business name and address and tax identification number (TIN);
  • Buyer Information: Name and address;
  • Date of Issue;
  • Unique Invoice Number;
  • Payment terms;
  • Description of Goods or Services;
  • Quantities and Unit Prices;
  •  

    In the U.S., including accurate tax information on invoices is essential for compliance and accurate accounting. Crucial information includes:

  • Sales Tax: If applicable.
  • Tax Exemption Status: If applicable.
  • Currency: Important for international transactions.
  • Amount Charged: The price of the goods or services, including a breakdown of taxes if applicable.
  • Total Amount Before and After Tax: Clearly state the subtotal before tax, the tax amount, and the total amount due after tax.
  •  

    B2G Invoicing Specifications

    B2G invoicing is subject to the most stringent requirements due to the high level of accountability required in government spending. These invoices must conform to established government standards and formats, like the Federal Acquisition Regulation (FAR). They must also include reference contract numbers and any other relevant agreement identifiers to ensure clear and compliant transactions with government entities.

     

    B2B Invoicing Specifications

    For B2B transactions, invoices typically require a higher level of detail. Detailed invoices provide a clear account of business transactions, facilitating accurate bookkeeping and financial management. You must include comprehensive information for each item or service, listing them separately with individual pricing. Additionally, a detailed breakdown of taxes, discounts, and shipping costs should be provided to ensure transparency and accuracy in the billing process.

     

    B2C Invoice Specifications

    For B2C transactions, a more simplified version of invoices is typically sufficient, requiring less information compared to full invoices.

    When issuing B2C invoices, you should include:

  • Seller's Name and Contact Details;
  • Date of the Transaction;
  • Description of Goods or Services;
  • Applicable State and Local Sales Taxes: if the business operates in a state that collects sales tax;
  • Total Amount Due: this should include all taxes, with clear payment instructions provided.
  • Typically, B2C transactions do not require the customer’s name or contact details, unless necessary for delivery or warranty purposes.

     

    Simplified invoices

    In the United States, there are no legally defined categories or thresholds for simplified invoices, unlike in some other jurisdictions. Although there isn't a specific legal framework mandating simplified invoices, businesses often opt to use them for smaller transactions or retail sales where detailed invoices are not necessary.

    A simplified invoice in the U.S. might typically include:

  • Seller Information: Name, address, and tax identification number (TIN);
  • Buyer Information: Name and address, if required for delivery or warranty purposes;
  • Date of Issue;
  • Description of Goods or Services;
  • Total Amount Due;
  • Sales Tax; if applicable.
  • Terms of Payment.
  •  

    Invoices Archiving

    In the USA, invoice archiving regulations primarily focus on the retention period required by federal and state tax laws. This period, often referred to as the period of limitations, determines how long you can amend your tax return to claim a credit or refund, or how long the IRS has to assess additional tax.

    The most common retention periods are:

  • Three years for income tax records. This standard period requires you to keep invoices that support items of income or deductions on your tax return. However, if you have underreported your income by more than 25%, the period extends to six years.
  • Seven years if you file a claim for a loss from worthless securities or bad debt deduction.
  • Indefinitely if you do not file a return or if you file a fraudulent return.
  • State requirements may extend beyond those of the IRS, depending on the type of tax or the nature of the business. For example, California and Texas require businesses to retain records for at least four years, while New York mandates a three-year retention period. It is crucial to consult local laws to ensure compliance with specific invoice archiving requirements in your state.

     

     

    E-invoicing Regulations

    Electronic invoicing, or e-invoicing, is the digital exchange of invoice information between a supplier and a buyer, often facilitated through electronic data interchange (EDI) as a common form of e-invoicing. The ability to send invoices electronically simplifies the billing process, allowing businesses to send invoices directly to customers’ accounting systems via a mobile app or web browser, efficiently marking invoices as sent or voiding them as necessary. Automated invoice processing enhances this efficiency by eliminating manual steps and data entry. An electronic invoice is a digital invoice created and processed in specific data formats like XML, designed to be machine-readable and digital throughout its entire lifecycle. The shift from paper invoices to electronic invoices highlights the inefficiencies of the former, such as delayed processing times and higher costs, and underscores the benefits of electronic invoices, including improved efficiency, faster payments, and compliance with tax authority regulations. This process not only streamlines operations but also significantly reduces the time spent on manual invoicing tasks.

    In the United States, there are no federal regulations that universally mandate the use of electronic invoicing across all businesses. However, the U.S. has introduced g-Invoicing, an initiative aimed at managing intragovernmental transactions electronically among federal agencies. While B2C, B2B, and B2G e-invoicing remains optional, many American businesses have proactively adopted this technology. The benefits of e-invoicing include improved operational efficiency, faster payment processing, and enhanced compliance with tax regulations, making it a preferred alternative to traditional paper-based invoicing. Using custom invoice templates can also further streamline and organize work, speeding up business processes and enhancing overall efficiency.

    The U.S. does not adopt a unified standard such as the Peppol standard used in some other regions. Instead, businesses in the U.S. typically select from various e-invoicing solutions provided by different vendors according to their specific needs.

    Since there is also no centralized platform in the USA, individual federal agencies might have their own specific requirements and systems for e-invoicing, designed to ensure secure and efficient processing of invoice data.

     

    Digital Validation Laws

    The USA has two key digital validation laws, the Uniform Electronic Transactions Act (UETA) and the Electronic Signatures in Global and National Commerce Act (E-SIGN), both of which promote the use of electronic transactions.

    UETA is aimed at facilitating electronic transactions within individual states by providing a legal framework that ensures electronic signatures and records are as legally binding as their paper equivalents. It is important to note that UETA applies only to transactions where both parties have agreed to conduct the transaction electronically. Currently, UETA has been adopted in 47 states, with New York, Illinois, and Washington opting out, each having their own laws regulating electronic transactions.

    E-SIGN, on the other hand, is designed to ensure the validity and legal effect of contracts formed or signed electronically across interstate and foreign commerce. E-SIGN is a federal law, applying uniformly across all states and superseding state laws, except in instances where a state has adopted UETA or a similar law. This makes E-SIGN a foundational pillar for the legal recognition of electronic signatures and records in the USA.

     

    E-invoicing Process

    In the United States, taxpayers and businesses have access to the Internal Revenue Service’s (IRS) e-Services, an online platform designed to facilitate various tax-related activities. This includes the electronic submission and management of documents crucial for tax compliance. Here’s an overview of how the process typically unfolds:

  • Completing a transaction: Taxpayers in the USA are encouraged to manage and submit their tax-related data electronically whenever possible. This includes electronically submitting invoice data after the delivery of goods or services, ensuring that the data is handled accurately and efficiently in formats compliant with IRS standards.
  • Upon submission: The IRS's electronic systems review the submitted data. This process involves verifying the details of the transaction and automating certain tasks related to tax document processing. Transactions may also be assigned a unique identification number for tracking and future reference.
  • After validation: Once validated, the taxpayer can issue a receipt or confirmation that includes their Taxpayer Identification Number (TIN) and may also incorporate additional security features like a QR code to facilitate quick verification.
  • The customer receives this receipt: The issued receipt typically includes the TIN and any other relevant security features, enhancing transparency and providing a means for verification.
  • Verification by customers or other interested parties: Verification of the transaction can be performed through the IRS website or via specific applications designed to manage and review electronic transactions, ensuring the integrity and accuracy of the tax-related data.
  •  

    Governmental Body Responsible for E-invoicing

    Governmental bodies responsible for e-invoicing in the USA at the federal level include the Internal Revenue Service (IRS), the General Services Administration (GSA) (which defines the standards and processes involved in e-invoicing within government contracts), and the Office of Management and Budget (OMB) (which encourages the adoption of e-invoicing to streamline operations and reduce costs).

    On the state level, the responsibility for e-invoicing lies with Individual State Agencies, each setting its own e-invoicing requirements as part of their procurement processes.

    In many cases, industry-specific e-invoicing standards are developed and managed by consortia or standards organizations rather than governmental bodies. For instance, in healthcare, standards for electronic transactions might be overseen by organizations like Health Level Seven International.

     

    E-invoicing Formats

    In the USA, the system for e-invoicing is managed through individual arrangements between businesses or according to specific standards set by industry sectors or government agencies, often in collaboration with the Internal Revenue Service (IRS) for tax-related aspects.

    Commonly used e-invoicing formats in the U.S. include:

    ANSI X12 Widely recognized standard in North America that includes a suite of XML-based business documents specifications.
    EDIFACT Internationally recognized standard, providing a unified specification for electronic data interchange, including electronic billing.
    UBL (Universal Business Language) Internationally recognized standard used by various entities for XML-based electronic invoicing processes.
    Custom XML/JSON Formats Many U.S. companies develop or adapt their own XML or JSON-based formats tailored for electronic invoicing processes to meet specific industry needs.

     

    E-invoices Data Validating

    Ensure that your e-invoices adhere to the specific USA requirements and standards relevant to your industry or any federal and state government entities you might be interacting with. The validation of e-invoices in the USA often depends on the standards set by individual industries or the specific electronic data interchange (EDI) systems in use. This variation means each business must ensure their e-invoicing systems comply with relevant standards and legal requirements, possibly including custom validations or digital certificates tailored to their specific operational and contractual needs.

     

    E-invoice Archiving

    In the United States, you must archive e-invoices for a minimum period of 3 years, aligning with the IRS requirements for keeping records to support items reported on tax returns. However, it is often advisable to keep these records for up to 7 years, as some states may have different requirements or in cases involving loss claims or bad debt deductions where the IRS requires retention for a longer period. The archiving period typically starts from the end of the fiscal year in which the invoices were issued. Archiving abroad is permitted, but it must comply with the IRS regulations concerning the accessibility, integrity, and retrievability of records.

     

     

    Tax Regulations

    In the United States, sales tax is applied to the sale of goods and services and is determined by the cumulative rates set by various jurisdictions. It comprises State Level Sales Tax, Local Level Sales Tax, and District Level Sales Tax. There is no federal sales tax in the U.S. This absence of a national sales tax helps prevent potential economic disparities across regions, which could disproportionately affect lower-income areas or those with different economic bases.

     

    State Level Sales Tax

    State-level sales tax in the United States is imposed on the sale of goods and services within individual states. Each state independently determines its own sales tax policies, including the tax rate, the specific goods and services that are taxable, and the manner in which the tax is administered.

    State sales tax rates are set at:

    State/s the tax rate applies: Sales Tax Rate
    Colorado 2.90%
    Alabama Georgia Hawaii New York Wyoming 4.00%
    Missouri 4.225%
    Louisiana 4.45%
    Oklahoma South Dakota 4.50%
    North Carolina 4.75%
    North Dakota Winsconsin 5.00%
    New Mexico 5.125%
    Virginia 5.30%
    Maine Nebraska 5.50%
    Arizona 5.60%
    Ohio 5.75%
    Florida Idaho Vermont Iowa Maryland Kentucky Michigan West Virginia South Dakota Pennsylvania 6.00%
    Utah 6.10%
    Illinois Texas Massachusetts 6.25%
    Connecticut 6.35%
    Arkansas Washington Kansas 6.50%
    New Jersey 6.625%
    Nevada 6.85%
    Washington 6.875%
    Indiana Mississippi Rhode Island Tennesse 7.00%
    California 7.25%

    Some states in the United States have no state sales tax due to various factors, including:

  • Significant revenue from other sources, such as natural resources, which reduce the reliance on sales taxes for income.
  • Income or property taxes that provide sufficient funding, making state sales taxes unnecessary.
  • A business-friendly environment that aims to attract more consumers and businesses by eliminating sales tax.
  • A strong resistance to taxes generally, which often stems from the state’s historical and cultural background.
  • The states without a state sales tax are Alaska (although local jurisdictions may impose sales taxes), Delaware, Montana, New Hampshire, and Oregon.

     

    Local and District Level State Tax

    In the United States, local and district-level sales taxes are levied in addition to state sales taxes by city, county, or special district governments.

    Local governments are typically empowered to impose local sales taxes. This includes setting their own rates and determining the taxability of various items within the constraints of state law. Consequently, local sales tax rates can vary significantly even within the same state, based on decisions and needs at the local government level.

    Special purpose districts, such as transportation, school, or health districts, may also impose district sales taxes aimed specifically at funding certain projects or operations. These taxes are often instituted following approval through voter referenda.

     

    The number of distinct local and district sales tax rates across the U.S. is enormous. For instance, states like Colorado and Alabama feature hundreds of different local sales tax rates, accounting for all the various municipalities and special districts involved.

     

    Use Tax

    Use tax is intended to be paid by the consumer for taxable items purchased where no sales tax has been applied. This typically includes purchases made from out-of-state vendors or through online and catalog sales. The primary purpose of use tax is to ensure that states still receive equivalent tax revenue for goods that are used, stored, or consumed within their jurisdiction when sales tax hasn't been collected by the seller.

    The use tax rate is the same as the sales tax rate that would have applied had the item been purchased within the buyer’s home state. If local sales taxes are applicable, these may also be included in the use tax rate.

    The method for reporting and paying use tax varies by state. Some states allow taxpayers to report and pay use tax on their state income tax return, providing a specific line item for this purpose. Others require separate reporting if no state income tax is filed.

     

    Corporate Sales Tax

    In the USA, the federal corporate tax rate is set at 21%.

    In addition to this federal rate, most states also impose their own corporate income taxes, which vary significantly in both rates and regulations.

     

    Sales Tax on Digital Products

    In the United States, digital services and products such as software, digital music, e-books, and streaming services are subject to state sales tax. The specific sales tax on digital products varies significantly as it is determined by the laws of each state, leading to a diverse array of tax regulations across the country.

     

     

    Sales Tax Payments and Returns

    In the United States, businesses are required to file a Sales Tax Return to report the sales tax amounts collected from customers. This report may also include deductions for sales tax paid on business purchases, depending on the specific state laws. The key components of the sales tax return typically include:

  • Sales Tax Collected on sales,
  • Deductible Sales Tax paid on business purchases, if allowed.
  • The net sales tax, which is the difference between the sales tax collected on sales and the deductible sales tax on purchases, is the amount that must be remitted to the state revenue department. If the deductions and credits exceed the sales tax collected, the business may be eligible for a refund.

    The frequency of sales tax reporting varies significantly among states:

  • Monthly: Returns are generally due by the 20th of the month following the reporting period. This frequency is typically required for businesses with higher sales volumes, though due dates can vary from the 15th to the last day of the month.
  • Quarterly: Returns are commonly due by the 20th of the month following the end of the quarter. This frequency suits businesses with moderate sales volumes, though it may vary by jurisdiction.
  • Annually: Returns are usually due by January 20th of the year following the tax period, with specific payment deadlines varying by state.
  • Sales tax reporting details, including due dates, reporting frequency, and methods for calculating deductions, can differ significantly from one state to another. Many states encourage or mandate the electronic filing and payment of sales tax via their online portals.

     

    Sales and Use Tax Registration Thresholds

    When navigating sales tax obligations in the USA, the term nexus is crucial. Nexus determines the obligation of a business, whether US-based or foreign, to register, collect, and remit sales tax in a particular jurisdiction. Nexus is categorized into two types: physical and economic.

    Physical nexus is established when a business maintains a physical presence within a state. This presence can be in the form of a retail store, warehouse, inventory, employees, or other physical assets located within the state. A business with a physical presence in a state is typically required to collect and remit sales tax on sales made within that state.

    Economic nexus, in contrast, occurs when a business has a significant economic presence in a state, regardless of physical presence. This is assessed based on a state-defined economic nexus threshold, which might consider the amount of sales or the number of transactions conducted with customers within the state. For instance, in California, businesses must collect and remit sales tax if their sales exceed $500,000 or if their sales to California customers represent more than 25% of their total sales.

     

    To safeguard small businesses from excessive tax burdens, most US states implement a tax registration threshold. A typical threshold might be 200 transactions or $100,000 in sales during the previous or current calendar year, ensuring that smaller entities are not overwhelmed by tax obligations.

     

     

    E-invoice Requirements

    In the USA, e-invoices typically require these essential elements:

  • Seller Information: Business name, address, and tax identification number (TIN).
  • Buyer Information: Name and address.
  • Unique Invoice Number;
  • Date of Issue;
  • Description of Goods or Services;
  • Quantities and Unit Prices;
  • Taxes and Total Amount: Includes the subtotal (before tax), the tax rate applied, taxes charged, and the total amount due after tax.
  • Payment Terms: Due date for payment, accepted methods of payment, and penalties for late payment, if any.
  • Terms and Conditions: Return policies or warranties associated with the goods or services sold.
  • The specific requirements for invoices can vary by state and industry, making it crucial for businesses to consult guidelines provided by accountants or legal advisors to ensure compliance with local regulations.

     

    Utilizing invoicing software can significantly benefit businesses in creating, sending, and managing e-invoices in compliance with the U.S. regulations. These tools not only help in generating professional invoices but also in streamlining the invoicing process, improving cash flow, and ensuring that payments are received on time.

    B2G E-invoice Specifications

    B2G e-invoices must adhere to specific governmental requirements, which often include standardized formats, purchase order references, audit trails, and regulatory details. These elements ensure the e-invoices are consistent, traceable, and compliant with the legal and procedural frameworks established by government entities. It’s also important to note, that clear payment terms and timely invoicing practices are crucial to avoid payment delays and ensure faster turnaround of payments.

     

    B2C E-invoice Specifications

    For B2C transactions, you can issue a more simplified version of invoices, which typically require less information than full invoices. Generally, these simplified invoices do not need to include the customer's name or contact details unless they are necessary for delivery or warranty purposes.

     

    Simplified E-invoice Requirements

    In the United States, there is no formal definition for a simplified e-invoice, nor are there specific issuing thresholds set by law. Despite the lack of a legal framework for simplified invoices, businesses may opt to use less detailed invoices for minor transactions or retail sales where a full detailed invoice is not necessary.

    A simplified invoice in the U.S. might typically include:

  • Seller Information: Name, address, and tax identification number (TIN);
  • Date of Issue;
  • Description of Goods or Services;
  • Total Amount Due: Both excluding and including taxes;
  • Payment Information: Details on how payment should be made.
  •  

     

    Digital Reporting R

    In the United States, digital reporting regulations are not universally mandated, and there is no unified national standard for digital reporting. Instead, the landscape is shaped by a variety of federal and state laws that dictate how certain types of information should be digitally reported.

    The IRS requires e-filing of most types of tax returns, particularly for businesses and tax professionals managing a large volume of returns. Additionally, businesses that collect sales tax are typically required to file Sales Tax Returns electronically in most states. This filing is done through state department of revenue services, which may utilize online portals, compatible business software, or through the services of a tax professional. These returns detail the sales tax collected and remitted by the business.

    Digital records, crucial for audit purposes, are generally mandated to be retained for a period ranging from three to seven years, depending on the type of record and the specific regulatory requirements governing those records.

     

    SAF-T

    SAF-T is not yet mandatory in the USA.

     

    Data Breaches

    If a data breach occurs in the United States, you must notify affected individuals as soon as possible after becoming aware of the incident. In addition, certain states require notification to state authorities or regulators depending on the severity and nature of the breach. This requirement aligns with the standards set by various state laws, as there is no overarching federal law governing data breach notifications for all private-sector organizations across the United States.

     

     

    Penalties

  • Late Filings: If you file your tax returns late, you may be fined a percentage of the tax due, which ranges from 2% to 25% of the amount owed.
  • Failure to Pay Tax: The IRS imposes a penalty of 0.5% per month on any unpaid tax amounts, which can accumulate up to 25% of your total tax owing.
  • Not Filing Tax Return: Not filing your tax return incurs a penalty of 5% of the tax shown on the return for each month it remains unfiled, up to a maximum of 25% of your tax due.
  • Negligence or Disregard: If you neglect or disregard tax rules or regulations, or if there is a substantial understatement of income tax, you will face a penalty of 20% of the underpayment.
  • Fraud: In cases involving fraud, the penalty increases to 75% of the underpayment attributable to the fraudulent activity.
  • In severe cases, such as tax evasion, penalties can extend beyond financial fines to include imprisonment, highlighting the critical need for adherence to tax laws.
