7 Mistakes You’re Making with Your Tax Refund (and How to Fix Them Fast)

NEW HAVEN, CT – Jose’s Tax Service – March 18, 2026

As the 2026 tax filing season reaches its peak, taxpayers across the nation are focused on one primary goal: securing their tax refund as quickly as possible. However, the Internal Revenue Service (IRS) routinely reports significant delays in processing returns due to preventable errors. Accuracy in filing is the most critical factor in determining the speed of a refund. Incomplete documentation, mathematical discrepancies, and administrative oversights can extend the processing timeline from weeks to months.

To maximize tax refund potential and ensure compliance with federal regulations, taxpayers must adhere to strict filing protocols. As a leading provider of tax preparation in New Haven, Jose’s Tax Service identifies the seven most prevalent mistakes currently affecting taxpayers and provides the necessary corrective actions to resolve these issues immediately.

1. Omit Health Insurance Documentation via Form 1095-A!

Taxpayers who obtained health insurance coverage through the Health Insurance Marketplace must account for the Advance Premium Tax Credit (APTC). Failure to include Form 1095-A, Health Insurance Marketplace Statement, is a leading cause of IRS processing holds.

The IRS uses the information provided on Form 1095-A to reconcile the credit paid to insurance providers on your behalf with the credit you are actually eligible for based on your final annual income. If this information is omitted, the IRS cannot calculate the correct tax liability.

How to fix it:

• Locate Form 1095-A before initiating the filing process.
• Use Form 8962, Premium Tax Credit (PTC), to reconcile the payments.
• Verify that the data entered matches the document exactly.
• Do not estimate these figures; use the official amounts reported by the Marketplace.

2. Report Estimated Tax Payments Inaccurately!

Self-employed individuals, freelancers, and small business owners are required to make quarterly estimated tax payments. A frequent error involves underreporting, overreporting, or entirely forgetting to list these payments on the final tax return. This mismatch triggers an automatic flag in the IRS system.

Discrepancies often occur when payments are made under a spouse’s Social Security Number (SSN) in a joint filing situation, or when the taxpayer loses track of the exact amounts paid during the fiscal year.

How to fix it:

• Consolidate all records of quarterly payments made throughout the year.
• Access the JTS Capital Dashboard if you are managing business finances through our integrated systems.
• Verify payment totals through the IRS Online Account tool.
• Ensure that all payments, including those made for state taxes, are attributed to the correct tax year.

3. Avoid Filing Before All Documents Arrive!

The desire to receive a refund early often leads taxpayers to file their returns before receiving all necessary income statements. While employers are required to send W-2s and 1099s by January 31, some documents, particularly those related to investments, brokerage accounts, or complex business interests, may arrive later.

Filing an incomplete return necessitates the submission of an amended return (Form 1040-X). Amended returns are processed manually and can take upwards of 16 to 20 weeks to resolve, effectively freezing your refund.

How to fix it:

• Create a checklist of all expected income sources, including interest (1099-INT), dividends (1099-DIV), and gig economy income (1099-K).
• Wait until the final week of February or early March if you expect late-arriving forms.
• Compare your year-end pay stubs to the final W-2 to ensure parity before submission.

4. Disregard Comprehensive Income Reporting!

The IRS receives copies of all 1099 and W-2 forms directly from payers. When a taxpayer fails to report income from a side hustle, a short-term contract, or bank interest, the IRS automated underreporter system detects the omission immediately. This leads to a "soft-stop" in processing.

In the current digital economy, many taxpayers overlook 1099-K forms issued by third-party payment processors. Failure to report this income may lead to penalties and interest charges in addition to refund delays.

How to fix it:

• Report every dollar of income, regardless of whether you received a physical form.
• Utilize a concierge tax pro to review your financial statements for overlooked revenue streams.
• Check for interest earned on high-yield savings accounts and dividends from app-based trading platforms.
• Review the Small Business Learning Center for guidance on reporting self-employment income.

5. Provide Incorrect Bank Account Information!

Direct deposit remains the most efficient method for receiving a tax refund, with the IRS issuing most refunds in this manner within 21 days of e-file acceptance. However, entering an incorrect routing number or account number is a catastrophic error.

If the bank rejects the deposit due to incorrect numbers, the IRS must then manually process and mail a paper check to the address on file. This adds weeks to the delivery time. In some cases, if the numbers belong to an active account owned by another individual, recovering those funds is exceptionally difficult and may require legal intervention.

How to fix it:

• Double-check the routing and account numbers against a voided check or your official banking app.
• Verify that the account is in the name of the taxpayer (or spouse if filing jointly).
• Confirm the bank’s ability to accept tax refunds if using a specialized or online-only financial institution.

6. Commit Errors in Personal and Dependent Details!

Simple typographical errors remain one of the primary reasons returns are rejected by the IRS e-file system. This includes misspelled names, transposed digits in Social Security Numbers, or incorrect dates of birth.

Furthermore, claiming a dependent who has already been claimed by another taxpayer (such as in cases of divorced parents) will cause an immediate rejection. The IRS requires that the name on the tax return match exactly what is on the Social Security card.

How to fix it:

• Physical copies of Social Security cards for all individuals listed on the return should be present during the preparation process.
• Ensure name changes due to marriage or divorce have been updated with the Social Security Administration (SSA).
• Coordinate with former spouses regarding dependency claims to avoid conflicting filings.
• Contact us at Jose’s Tax Service to ensure your data entry is performed with professional oversight.

7. Submit Math Errors and Ineligible Credit Claims!

Mathematical inaccuracies, particularly when calculating the Earned Income Tax Credit (EITC) or the Child Tax Credit (CTC), are heavily scrutinized by the IRS. The PATH Act (Protecting Americans from Tax Hikes Act) mandates that the IRS hold refunds for returns claiming these credits until mid-February to verify eligibility. If the calculations are incorrect, the hold is extended indefinitely while the IRS requests proof of residency or relationship.

Using software does not prevent all errors, as the "garbage in, garbage out" principle applies. If the initial data provided regarding income or filing status is incorrect, the software will generate an inaccurate result.

How to fix it:

• Review the eligibility requirements for all credits and deductions before claiming them.
• Retain supporting documentation, such as school records or medical records, to prove dependent residency.
• Professional review is highly recommended for taxpayers with complex family situations or fluctuating incomes.
• For a comprehensive analysis of your eligibility, you may request a quote form to see how our services can assist in maximizing your legal return.
