The one-time refund surge from the One Big Beautiful Bill Act, which delivered $296 billion in IRS refunds during the 2026 filing season and contributed 0.4 percentage points to U.S. GDP in the first half of the year, has largely run its course, removing a meaningful spending cushion from consumers and small business owners at the same time mortgage rates are crossing 7% and borrowing costs are climbing across every major credit category.
Key Takeaways
- The IRS issued $296 billion in refunds during the 2026 filing season, a 17% increase ($43 billion more) over the prior year, with the average individual refund climbing 11% to $3,275 from $2,942.
- The Brookings Institution’s Fiscal Impact Measure estimates the income boost from the OBBBA’s tax provisions contributed 0.4 percentage points to GDP in the first half of 2026; that contribution is now fading as the refund cycle completes.
- The OBBBA made the Section 199A pass-through deduction permanent, delivering approximately $4,600 in average tax relief to 8 million entrepreneurs, and reduced taxes for over 12 million small business owners by roughly $7,000, per the U.S. Department of the Treasury.
- The 30-year fixed-rate mortgage reached 7.19% following the September 16 Fed rate hike, and there is typically a six-month lag before reduced home sales translate into lower spending on furniture, appliances, and home goods.
- The Congressional Budget Office projected the OBBBA would add 0.9 percentage points to real GDP in 2026 as provisions take full effect, but distributional analysis shows the lowest-income 20% of earners will see a net loss in resources when tax cuts are combined with reduced medical and food benefits.
The $296 Billion Refund Surge Was a One-Time Economic Event
The scale of the 2026 refund season was, in large part, a mechanical consequence of a timing decision. When President Trump signed the One Big Beautiful Bill Act on July 4, 2025, the legislation reduced individual income taxes for the 2025 tax year by an estimated $129 billion, creating new deductions for tips and overtime income, increasing the child tax credit to $2,200, raising the standard deduction to $15,750 for single filers and $31,500 for joint filers, and quadrupling the state and local tax deduction cap from $10,000 to $40,000. The IRS, however, did not update withholding tables for the 2025 tax year. That meant most workers continued to see the same paycheck amounts throughout 2025, and the full benefit of the tax cuts arrived as a lump-sum refund when they filed their returns in early 2026.
The result was a historic refund season. The IRS issued $296 billion in total refunds, $43 billion more than the prior year, a 17% increase. The average individual refund rose $333 to $3,275, an 11% jump. The Government Accountability Office attributed the increase partly to millions of taxpayers claiming new deductions created by the OBBBA, including the tips and overtime provisions. Morgan Stanley had projected refunds would increase 15% to 20% on average, and the Tax Foundation estimated the major tax changes for 2025 would produce an average tax cut of $611, representing a 0.8% increase in after-tax income.
That Stimulus Contributed Measurably to GDP, and Its Absence Will Be Felt
The Brookings Institution’s Fiscal Impact Measure estimated that the income boost from lower taxes contributed 0.4 percentage points to U.S. GDP in the first half of 2026. Americans for Tax Reform projected that if 80% of the extra refunds were spent and distributed evenly across the first two quarters, the spending could boost annualized real GDP growth by more than 0.5% in Q1 alone. The Congressional Budget Office projected the OBBBA would add 0.9 percentage points to real GDP in 2026 as the legislation’s provisions take full effect, a figure that factors in both the refund cycle and the lower withholding tables that began applying to 2026 paychecks.
The distinction between the one-time refund surge and the ongoing withholding adjustment matters for understanding what fades and what persists. Updated withholding tables for 2026 mean paychecks are now modestly larger on a recurring basis, providing a steady but smaller drip of additional spending power. The refund surge, by contrast, was a concentrated injection of cash into household budgets between February and May. That injection has now been absorbed. It was spent on groceries, auto repairs, credit card balances, small business inventory, and the everyday expenses that households prioritize when a lump sum arrives. The question for Q4 2026 is what fills that gap.
Small Business Owners Received Significant but Front-Loaded Relief
For entrepreneurs and small business owners specifically, the OBBBA’s provisions were substantial. The U.S. Department of the Treasury reported that the tax cuts reduced taxes for over 12 million small business owners by roughly $7,000 on average. The permanent extension of the Section 199A pass-through deduction, which allows pass-through business owners to deduct 20% of qualified business income, is delivering approximately $4,600 in average annual tax relief to 8 million entrepreneurs, per the Small Business Administration. The legislation also restored 100% bonus depreciation for businesses, allowing immediate write-offs of qualifying equipment and capital investments rather than depreciating them over multiple years.
These provisions are permanent or multi-year, meaning their benefit extends beyond the 2026 refund cycle. The Section 199A deduction will continue to reduce taxable income for pass-through entities indefinitely. The overtime and tips deductions run through 2028. The increased standard deduction and child tax credit are indexed to inflation going forward. The ongoing benefit is real, but it arrives through incrementally smaller paychecks rather than the concentrated refund check that front-loaded much of the economic impact into the first half of the year. For a sole proprietor or small LLC owner, the $4,600 annual benefit from the 199A extension is meaningful over time, but it does not replace the one-time refund check that may have been used to cover a late rent payment, restock inventory, or retire a line of credit balance.
The Fading Tailwind Meets Rising Borrowing Costs at the Worst Possible Moment
The timing of the refund cycle’s completion coincides with an environment in which nearly every other consumer-facing economic indicator is tightening. The Federal Reserve raised the federal funds rate to 3.75%–4% on September 16, the first hike since 2023. The 10-year Treasury yield crossed 5% on September 14. The 30-year fixed-rate mortgage reached 7.19%. Credit card balances hit $1.26 trillion in Q2 2026, a new record for the eleventh consecutive quarter, with the average APR for cards accruing interest at 22.15%. Auto loan balances reached $1.69 trillion, with delinquency rates ticking higher.
The housing market is where the fading tax tailwind and rising rate headwind intersect most directly. The NAHB/Wells Fargo Housing Market Index fell to 32 in September, with builders citing rising mortgage rates as the primary driver of weakened buyer traffic. Home sales were already slowing before the September rate hike, and research consistently shows a roughly six-month lag between declining home sales and reduced consumer spending on big-ticket household goods. Furniture, appliances, home renovation materials, and flooring purchases are among the categories most sensitive to housing transaction volume. That lag means the current mortgage rate environment may not fully register in consumer durables data until the first quarter of 2027, extending the drag beyond the Q4 2026 window that is already looking more difficult for consumer-facing businesses.
The Distributional Question Complicates the Economic Picture
The OBBBA’s economic impact has not been uniform. RBC Economics described a “barbell” effect, in which higher-income households and business owners receive the most direct benefit from the tax provisions, while lower-income households receive less or, in some cases, experience a net loss when reduced government benefits are factored in. The Congressional Budget Office projected that from 2026 to 2034, the lowest-income 20% of earners will see a net loss in resources, combining the tax changes with reductions in medical and food assistance, while the top 10% of earners will see their resources increase by approximately $13,600 per year. That distributional pattern matters for consumer spending forecasts because lower-income households tend to spend a higher proportion of any income change, meaning a net loss at the bottom of the income distribution has a larger per-dollar impact on aggregate demand than an equivalent gain at the top.
For entrepreneurs serving middle-income and lower-income consumers, the implication is concrete: the customers who were most likely to spend their refund checks immediately are the same customers who may see reduced purchasing power as government benefit adjustments take effect and the refund cycle fades. Businesses that benefited from the spring spending bump may need to plan for a Q4 and Q1 2027 environment in which the consumer looks noticeably different than the consumer who walked through the door in March.

FAQs
How Much Did Tax Refunds Increase In 2026?
The IRS issued $296 billion in refunds during the 2026 filing season, a 17% increase over the prior year. The average individual refund rose 11% to $3,275, up from $2,942 in 2025. The increase was driven by new deductions created by the One Big Beautiful Bill Act, including provisions for tips, overtime, and an increased standard deduction.
What Tax Provisions Benefit Small Business Owners Under The OBBBA?
The OBBBA made the Section 199A pass-through deduction permanent, delivering approximately $4,600 in average annual tax relief to 8 million entrepreneurs. It also restored 100% bonus depreciation, increased the SALT cap to $40,000, and raised the estate tax exemption to $15 million. The U.S. Department of the Treasury reported the law reduced taxes for over 12 million small business owners by roughly $7,000.
Why Is The Tax Refund Boost Considered A “Fading Tailwind”?
The IRS did not update withholding tables for 2025, so the tax cuts arrived as a concentrated lump-sum refund in early 2026 rather than through larger paychecks over the course of 2025. That one-time cash injection, which the Brookings Institution estimated contributed 0.4 percentage points to GDP in the first half of the year, has now been spent and will not repeat at the same scale in 2027.
How Do Rising Mortgage Rates Compound The Problem?
The 30-year fixed-rate mortgage reached 7.19% after the September 16 Fed rate hike. Home sales were already slowing, and there is typically a six-month lag before a housing slowdown translates into reduced spending on furniture, appliances, and home goods. The current rate environment may not fully impact consumer durables until early 2027.
Which Consumers Are Most Affected By The Fading Stimulus?
The Congressional Budget Office projected that the lowest-income 20% of earners will see a net loss in resources from 2026 to 2034 when tax cuts are combined with reductions in food and medical benefits. Lower-income households, which tend to spend a higher proportion of any income change, were most likely to spend refund checks immediately, making the fading tailwind disproportionately impactful at the consumer level.
