Filing Deadlines and the Call Volume Nobody Forecasts
Most forecasting models in financial services are built on history: last year’s volume, adjusted for growth. Filing season breaks that approach, because its peaks are not spread across the quarter. They arrive as short, dense spikes, each tied to a date the IRS publishes a year in advance. The tax filing deadline call volume a bank, lender or fintech receives is the most predictable surge in its calendar and one of the least planned for. Customers call to find a tax form, to confirm a refund deposit, to pay a balance due or to fix a direct debit that bounced. The questions change with each deadline, and so does the shape of the spike. Treated as a series of dated events, the season becomes plannable.
A Season Made of Dates, Not Months
The dates are public long before they matter. The IRS tax calendar for 2027, published in draft, keeps the familiar pattern: information returns such as Forms 1098 and 1099 generally due to recipients around February 1, individual returns due in mid-April, estimated payments in April, June and September, and the extension deadline in mid-October.
Each of those dates sends customers to their financial institution for something different. In early February it is paperwork. In March it is money arriving. In April it is money leaving. A forecast that only counts calls cannot see that difference, and staffing built on it puts the wrong skills on the floor at the wrong time.
The early weeks are busier than many teams assume. IRS filing season statistics for late February 2026 show 51.5 million returns already received and 36.5 million refunds issued by February 27, with an average refund of $3,742. A large share of filers act within weeks of their forms arriving, so the contacts tied to those forms arrive early too.
None of this is unusual volume management. It is the same discipline behind general tactics for absorbing sudden spikes, applied to spikes whose dates are known a year ahead.
The Deadlines and the Contacts They Create
The table reads left to right: the date, what reaches the customer, and what they contact their bank, lender or fintech about as a result. The last column describes the shape of the spike.
| Date (approximate) | What lands | What customers contact you about | Shape of the spike |
|---|---|---|---|
| Mid-January | Final estimated payment for the prior tax year | Payment confirmations, transfer limits, failed debits | Short and tight around the date |
| Around February 1 | Forms 1099-INT, 1099-DIV, 1098 and similar sent to customers | Where is my form, duplicate copies, online access, corrections | Builds immediately after the date and lasts for weeks while people file |
| Late February to March | Refund deposits, including those held until mid-February by law | Deposit status, holds, account access, payoff and extra payments | Rolling waves as refunds are released |
| Mid-April | Filing deadline and first estimated payment of the new year | Paying a balance due, debits from the IRS, overdrafts, payment arrangements | The sharpest spike of the season, concentrated in the days around the deadline |
| Mid-June and mid-September | Second and third estimated payments | Payment confirmations and transfer questions | Small, short spikes |
| Mid-October | Extension deadline | Late requests for tax forms and corrected statements | A second, smaller wave of February’s questions |
February is about documents; April is about payments. Those require different knowledge and different authority. An agent who can reissue a Form 1098 in February may not be the right person to discuss a hardship arrangement in April.
The document wave is the most avoidable. Most requests are for forms the customer could retrieve online, and the rest are corrections that need a back-office process. Teams that are good at handling document requests and status questions publish the forms early, make online access obvious and keep a clear route for genuine corrections.
The April wave is about money and urgency. Customers who owe tax and are short of funds look for room: a skipped payment, an increased limit, a hardship plan. Institutions that offer account and payment support for banks and lenders plan this window around payment arrangements rather than general inquiries.
The October wave is easy to forget because it is small. It is also the one most likely to catch a team unprepared, because by then the seasonal staff and the February scripts are long gone. Extension filers ask February’s questions in October, and the answers need to still be on hand.
Turning the Calendar Into a Plan
The practical steps follow from the table, and every one can be decided months before the first date.
- Forecast by contact type, not total volume. Document requests, deposit questions and payment problems need different staff
- Publish before the date. Form availability, online access and refund-deposit timing explained on the website and in the app before customers ask
- Staff the days after each deadline. The spike follows the date; coverage for the whole season wastes budget in the quiet weeks
- Set the boundaries. Agents explain the institution’s forms and payments; they do not give tax advice
The refund weeks deserve their own planning, because deposits trigger payoffs, extra payments and access questions all at once. The structure behind a readiness calendar built around refund season applies the same idea to that slice of the year.
The cheapest capacity is the capacity you only pay for in the weeks you need it. For most institutions that means a small permanent team with trained surge support for early February and mid-April. Flexible arrangements that add extra capacity across phone, chat and email for those windows avoid hiring for a peak that lasts days.
Conclusion
Filing season is not one surge but a series of dated spikes, each driven by a different event and each bringing a different question. The dates are published a year ahead; the only unknown is whether the plan uses them. Forecasting by contact type, publishing answers before each deadline and staffing the days after it turns the season from a scramble into a schedule. If your current forecast treats January to April as one block of extra volume, rebuild it around the six dates in the table.
FAQ: Filing Deadlines and the Call Volume Nobody Forecasts
1. Why do banks and lenders get more calls during tax season?
Because filing deadlines send customers looking for things only their financial institution holds: interest and mortgage tax forms, records of payments, confirmation of refund deposits and help with paying a balance due. Each deadline produces its own type of contact.
2. When are banks required to send tax forms such as 1099-INT and 1098?
Generally by around February 1. The IRS’s draft 2027 tax calendar keeps that as the general due date for giving recipients Forms 1098 and 1099. Requests for missing, duplicate or corrected forms follow in the weeks after.
3. Which tax deadlines create the biggest contact spikes for financial firms?
Usually the form furnishing date in early February and the individual filing deadline in mid-April, followed by smaller waves around the estimated tax dates in January, June and September and the extension deadline in mid-October.
4. How can a financial institution prepare its contact center for filing season?
Map each deadline to the contact type it creates, publish answers and self-service access for the predictable questions before the date, schedule extra coverage for the days after each deadline rather than the whole season, and train agents on what they can and cannot say about tax matters.
