Both Forms 1099-INT and 1098 help individuals and businesses to report financial transactions (interest) to the IRS. The Form 1098 reports mortgage interest, and the Form 1099-INT reports interest income paid out. However, there are multiple differences between the two that could help payers avoid mistakes in their tax returns. 

Form 1099-INT 

A 1099-INT form is necessary if a business issued an interest payment of at least $10 annually. It consists of different types of interest, including savings account interest, bond interest, and investment interest. 

You also need this form if your firm paid $600 or more in interest as late death benefits payments from an insurance company, damage settlement, or interest on state or federal tax refunds. Besides, businesses, banks, government agencies, or financial institutions file this interest income reporting IRS form. 

Form 1098 

A 1098 Form is only necessary for mortgage interest payments or mortgage insurance payments. The borrower has to issue this form if they contribute $600 or more in a tax year. Besides, businesses must report if a borrower has already overpaid interest in the prior year. Then, businesses should refund or credit that overpayment. 

Banks, credit unions, businesses, or even individuals can act as lenders to fill out Form 1098. The form highlights how much mortgage interest a lender has received from a borrower.   

Tax professionals and accounting departments need an automated solution to improve consistency for 1099-INT/1098 tax mailing. You cannot compromise your tax document fulfillment with manual exports, print runs, and multiple vendor handoffs. 

That’s where PostGrid’s Automated Print & Mail Solution fits in with its scalable infrastructure and native integrations. Let’s see how it can transform your tax statement delivery with automation. 

Lower Manual Bottlenecks 

Any in-house tax mailing workflow relies on manual exports, proofing cycles, print queues, envelope stuffing, and juggling with a local print vendor. So, there are multiple interdependencies and possibilities of hand-off errors. PostGrid, on the other hand, offers end-to-end 1099-INT/1098 tax mailing. So, your team can schedule tax documents with a single automated workflow. 

Improve Document Visibility 

It is often hard for teams to keep track of physical mailings once they leave the building. There are tracking mechanisms, but they require high manual intervention and continuous monitoring using different tools. Above all, PostGrid offers complete visibility to financial tax documents via its dashboard. So, your teams can answer recipient questions and be confident about the delivery timelines. 

Scale Efficiently 

Scaling tax document fulfillment with in-house workflows requires an extensive investment in printers and additional seasonal staff. In contrast, PostGrid uses its distributed print network spread across the country to scale with any seasonal spikes. So, it helps you avoid delays and bottlenecks for 1099-INT/1098 tax mailing. 

Meet IRS Deadlines Without the Last-Minute Rush 

The IRS enforces a strict deadline of January for 1099-INT/1098 tax mailings. Beyond this point, you have to pay per-form penalties for every single late document. Automated tax document fulfillment removes redundancies and bottlenecks from the printing and mailing operations. Besides, PostGrid offers an industry-leading 2-business-day SLA to process, print, and hand over documents to mailing carriers. 

Ensure Accurate Delivery With Address Verification 

Every undelivered 1099-INT/1098 tax mailing could lead to a serious compliance gap and wasted time. IRS won’t take such cases lightly and is likely to penalize the organization filing the document. For this reason, PostGrid offers built-in USPS CASS-certified address verification and NCOA processing. So, you can spot invalid, incomplete, or outdated addresses before printing anything.  

Cut Postage and Printing Costs at Scale 

Outsourcing 1099-INT/1098 tax mailings to PostGrid helps you access distributed print networks, USPS presort discounts, and bulk pricing. It requires multiple permits and paperwork when you try to obtain these savings with an in-house workflow. So, automation lets you enjoy a much lower cost per piece than any DIY approach. 

Stay Audit-Ready With a Complete Mailing Trial 

The IRS, state agencies, and internal auditors might demand complete details of your mailing operations. You need proper audit trails for every mailpiece and mailroom activity. PostGrid’s solution provides timestamped mailing trials with instant searchability. As a result, you can pull real evidence in seconds without going through piles of paper receipts. 

Avoid Compliance Risks 

1099-INT/1098 tax mailings can carry sensitive PII, account numbers, TINs, and interest amounts. You always need a fully compliant printing and mailing infrastructure that ensures confidentiality and data integrity. PostGrid is compliant with HIPAA, PIPEDA, SOC 2 TYPE 2, PCI DSS, and GDPR guidelines. So, it helps you avoid legal risks and financial penalties from federal and state agencies.

Tax form printing and mailing with PostGrid is simple, efficient, and fast. Your team doesn’t have to worry about a steep learning curve to use PostGrid during the tax season. Here are five simple steps to automate 1099-INT/1098 tax mailings; 

Connect PostGrid With Existing Systems 

Automation begins with the systems and tools that store your customers and documents. PostGrid can connect with multiple CRMs, such as Salesforce, HubSpot, and more. Besides, you can also integrate ERPs and accounting platforms like QuickBooks and custom internal systems. Besides, complete API documentation is available to help you build custom solutions. 

This connection helps you pull recipient details, interest amounts, account numbers, and mailing addresses directly from existing systems. So, there’s no need for manual data entry or CSV file uploads. 

Create Templates With Variable Data Printing (VDP)

Next, you can create templates using PostGrid’s built-in HTML template editor or by uploading your own IRS-compliant layout. Then, Variable Data Printing technology dynamically autopopulates templates with variable fields, recipient names, addresses, TINs, account numbers, interest amounts, and more. 

The dynamic personalization is vital to reuse templates and scale high-volume financial tax documents. Meanwhile, branding and formatting remain consistent across individual mailpieces. So, at the end of the day, there’s less repetitive work for your team. 

Define Trigger Rules 

Triggers define when to print and mail tax documents automatically. You can set a year-end batch trigger on a specific date for 1099-INT/1098 tax mailings. Moreover, PostGrid also supports event-based triggers for corrected forms, account closures, and on-demand reprints. So, it helps you leave your print and mailing workflow on autopilot, while you focus on other critical tasks. 

Automate the Print and Delivery 

PostGrid moves the orders through the production floor once you trigger a request. It includes printing, inserting, sorting, enveloping, addressing, and routing the 1099-INT/1098 tax mailings to the postal carriers. Above all, you don’t need to dedicate in-house resources to any of these processes. 

The centralized online dashboard lets you create and manage mailing campaigns from anywhere and from any device. Besides, a distributed printing network means mailers are printed closer to their destination. It shortens the delivery time and lowers postage. 

Monitor Individual Mailpiece From a Centralized Dashboard

It is often hard for teams to monitor the delivery status of 1099-INT/1098 tax mailings manually. In contrast, PostGrid’s dashboard lets you see when individual mail was processed, printed, in transit, delivered, or returned. Besides, you can rely on USPS Intelligent Mail barcode (IMb) tracking and carrier tracking to monitor the real-time status of every mailer.

The IRS runs physical 1099 forms via high-speed scanning equipment. For this reason, the way you create your 1099-INT/1098 tax mailings impacts the decision whether they will be accepted or rejected. Even a minute mistake can make your submission go to waste. 

Always Use Official Scannable Forms 

The IRS’s optical character recognition equipment cannot process standard printouts. So, you cannot print a copy from the IRS website as a regular PDF. For this reason, it becomes essential to order IRS-approved versions from office supply vendors. You need the official red-ink Copy A of the 1099 Form. 

Assemble Form 1096 Transmittal 

Every batch of 1099s requires a Form 1096 as a cover sheet. This document summarizes the total number of 1099 forms and informs the IRS about the types of returns. Besides, a separate 1096 is necessary if your organization is filing for more than one type. 

Use a flat mailer to place each Form 1096 and the corresponding stack of Copy A forms. However, avoid folding, stapling, taping, or paper-clipping the forms together under any condition. Any of the following could hinder the IRS scanning equipment and lead to rejections. 

Consider the Filing Deadlines 

All entities are required to mail 1099-NEC forms before the IRS deadline of January 31. The deadline remains the same for the recipient’s copy. So, there’s no additional buffer between the two documents. 

February 29 is the deadline for 1099-MISC and other types, including 1099-DIV and 1099-INT. The deadline will shift to the next business day if it falls on a Saturday, Sunday, or a public holiday. So, it is highly recommended to use Certified Mail with return receipt for peace of mind.

It is possible to request a 30-day extension by filing Form 8809 before the original due date. However, there could be different rules depending on which 1099 type you want to file. For most 1099 forms, the 30-day extension is available. Besides, there’s no need to explain why you might need more time to file. 

Form 1099-NEC is the main exception. It is mandatory to submit a signed Form 8809, explaining the eligible hardship reason. The reason could be anything from disaster to serious illness, or being the first year of business. After all, the IRS only offers a 30-day extension for 1099-NEC. 

1099-INT/1098 tax mailing automation works best when you integrate PostGrid with existing systems. It makes the mailers triggered, personalized, and more trackable than manual workflows. 

CRMs and Customer Data Integration 

Integrations for CRMs help you sync recipient-specific data and set up event triggers to send financial tax documents. These triggers could be anything, such as a new account, a mortgage milestone, or a missed payment. 

ERP and Accounting System Integration 

1099-INT/1098 tax forms live inside ERP or accounting systems. PostGrid offers native integrations for QuickBooks and other financial platforms. So, you can directly pull interest amounts, balances, and other reporting information into templates automatically. There’s no need for manual data entry or file uploading to set up mailings for your finance team every January. 

REST API and No-Code Options 

Developers can access PostGrid’s REST API for custom applications and deep integrations. Then, native SDKs are available for different programming languages. It makes it possible to save custom development time and effort. 

Non-tech-savvy teams can use no-code integrations like Zapier or Make to connect with thousands of tools. Then, they can build automated workflows to send IRS compliance mailings.

PostGrid lets you use multiple USPS services depending on time-sensitivity and security concerns. 

Priority Mail 

USPS Priority Mail can ship year-end tax statements in one to three business days. It offers tracking capabilities and insurance of up to $100 on most items. Above all, this service balances speed, cost, and traceability, which are necessary for financial tax documents. Also, the IRS accepts USPS postmarks as timely proof of mailing. 

Priority Mail Express 

USPS Priority Mail Express is the fastest mailing service you can use to deliver tax documents with a next-day to two-day delivery guarantee. This service also carries an insurance coverage of $100. However, you can also purchase additional coverage of up to $5,000. It is the ultimate choice when speed is superior to per-piece cost. 

First-Class Mail 

USPS First-Class is the most efficient mailing option that delivers your tax documents within one to five business days. However, you don’t get tracking capabilities by default. So, most businesses pair it with Certified Mail if they need proof of mailing. You should only consider this when you have a good buffer time before the deadline while sending tax documents. 

Certified Mail

Adding USPS Certified Mail helps you get an official mailing receipt. So, the request for a Return Receipt (physical green card or electronic). This receipt works as a legal proof of mailing and delivery for the IRS and the court. You should always consider it for high-value recipients or corrected filings. 

Registered Mail 

USPS Registered Mail is the most secure USPS add-on service. It provides you with detailed real-time tracking information of every handover in the USPS ecosystem. There’s an insurance coverage of $50,000, and it needs a recipient's signature to receive mail. It might be slower than Priority and Priority Mail Express, but it is ideal for sending documents with sensitive information.
