The IRS ‘Where’s My Refund’ tool went live for 2025 returns on January 27, 2026, and the April 15, 2026 filing deadline means millions of taxpayers are checking it right now. The 2026 standard deduction rose to $15,750 for single filers and $31,500 for married-joint filers — a roughly 2.7% inflation adjustment under Rev. Proc. 2025-32 — which directly determines whether your refund is larger or smaller than last year’s.
How the IRS ‘Where’s My Refund’ Tool Works on April 15, 2026
Go to IRS.gov/refunds and enter three pieces of information: your Social Security number or ITIN, your filing status, and the exact refund amount shown on your return. The tool updates once per day, typically overnight, and shows one of three statuses: Return Received, Refund Approved, or Refund Sent.
E-filed returns with direct deposit receive refunds in 21 calendar days or fewer in most cases. Paper returns take 6–8 weeks from the date the IRS receives them. If you filed a paper return on April 15, 2026, do not expect a refund before mid-June at the earliest.
The IRS2Go mobile app mirrors the same data as the web tool. If you need a transcript rather than a refund status, use the IRS Get Transcript service, which shows line-by-line return data and is useful if the tool shows a discrepancy.
The $15,750 Standard Deduction: How It Shrinks or Grows Your Refund
Your refund is the difference between what you owed and what your employer withheld (or what you paid in estimated taxes). The standard deduction is the first lever. For tax year 2025 — the return due April 15, 2026 — the deductions are:
| Filing Status | 2025 Deduction | 2026 Deduction |
|---|---|---|
| Single | $15,000 | $15,750 |
| Married Filing Jointly | $30,000 | $31,500 |
| Head of Household | $22,500 | $23,625 |
The figures in the left two columns apply to your 2025 return due now. The 2026 column applies to the return you will file in April 2027. If you are adjusting your W-4 withholding today to calibrate next year’s refund, use the 2026 numbers.
The Child Tax Credit for the 2025 tax year (filed April 15, 2026) is up to $2,200 per qualifying child. That credit is refundable in part through the Additional Child Tax Credit, which is why PATH Act delays apply to returns claiming it.
2026 Tax Brackets: The Indexed Numbers That Set Your Marginal Rate
The IRS indexed all seven brackets upward approximately 2.7% for 2026 under Rev. Proc. 2025-32. The top marginal rate remains 37%. For a single filer, the 22% bracket now begins at $48,475 and the 24% bracket at $103,350 — both higher than 2025, meaning the same nominal income is taxed at a lower rate than it was last year, which can produce a slightly larger refund if withholding was calculated on 2025 tables.
April 15, 2026 Deadline: What Happens If You Miss It
Today is April 15, 2026 — the filing deadline for 2025 federal returns. If you cannot file by midnight tonight, submit Form 4868 electronically before midnight to receive an automatic six-month extension to October 15, 2026. The extension covers filing, not payment. Any tax owed was due today; interest accrues at the federal short-term rate plus 3 percentage points starting April 16.
The failure-to-file penalty is 5% of unpaid tax per month, up to 25%. The failure-to-pay penalty is 0.5% per month. Filing on extension and paying what you owe eliminates the larger penalty entirely.
The $24,500 401(k) Limit and Who Gets the $11,250 Super Catch-Up
While you are waiting on your refund, the smartest move is to redirect it into tax-advantaged accounts before contribution deadlines. The 2026 401(k) employee deferral limit is $24,500, up from $23,500 in 2025. Workers 50 and older can add an $8,000 catch-up contribution for a total of $32,500.
Workers aged 60 through 63 qualify for the SECURE 2.0 “super catch-up” of $11,250 instead of the standard $8,000, bringing their total to $35,750. This window closes at age 64, so if you turn 64 in 2026, this is your last year to use it.
IRA contributions for tax year 2025 can still be made until April 15, 2026 — today. A $7,000 traditional IRA contribution (the 2025 limit) made right now reduces your 2025 taxable income if you are eligible for the deduction. The 2026 IRA limit is $7,500, with a $1,100 catch-up for those 50 and older, bringing the total to $8,600.
HSA Contributions Through April 15, 2026 Can Still Cut Your 2025 Bill
Like IRAs, Health Savings Account contributions for tax year 2025 are accepted through today’s deadline. The 2025 HSA limits were $4,150 self-only and $8,300 family. If you did not max those out, you can still deposit the difference today and deduct it on your 2025 return — potentially increasing your refund or reducing what you owe.
For 2026 contributions going forward, the HSA limits are $4,400 self-only and $8,750 family, with a $1,000 catch-up for account holders 55 and older. The FSA limit for 2026 is $3,400.
Social Security in 2026: The 2.5% COLA and the $176,100 Wage Base
If Social Security benefits are part of your household income, the 2.5% COLA that took effect January 2026 raised the average retired-worker benefit to approximately $1,976 per month. The maximum benefit at Full Retirement Age (67 for anyone born 1960 or later) is about $4,018 per month.
You are a single filer who just received a $3,200 federal refund on April 15, 2026. You are 52 years old, have no IRA for 2025 yet, and your employer’s 401(k) is only half-funded for 2026. You have three options for the $3,200.
The Social Security wage base for 2026 is $176,100, up from $176,100 — check SSA.gov/cola for the official announcement. Workers earning above that threshold stop paying the 6.2% employee share of Social Security tax mid-year, which affects net pay and withholding calculations.
If you are under Full Retirement Age and collecting Social Security while still working, the 2026 earnings test limit is $23,400 per year. The SSA withholds $1 in benefits for every $2 you earn above that. In the calendar year you reach FRA, the limit jumps to $62,160, with $1 withheld per $3 above. Benefits withheld under the earnings test are not lost permanently — the SSA recalculates your benefit upward at FRA.
Medicare Part B at $206.50: How It Affects Your Refund Math
For retirees who have Medicare Part B premiums deducted from Social Security, the standard 2026 premium is $206.50 per month, up from $185.00 in 2025. That $21.50 monthly increase — $258 annually — partially offsets the 2.5% COLA for many beneficiaries.
Higher-income Medicare enrollees pay more through IRMAA surcharges. The 2026 IRMAA brackets start at $106,000 modified adjusted gross income for single filers and $212,000 for married-joint filers, per Medicare.gov. If your 2024 income (which Medicare uses for 2026 premiums) crossed those thresholds, your Part B premium is higher than $206.50 — and that higher deduction from your Social Security check reduces the gross benefit you report on your tax return.
The Part B deductible in 2026 is $257. Medical expenses exceeding 7.5% of adjusted gross income remain deductible for itemizers — but with the standard deduction at $31,500 for married filers, itemizing requires significant qualifying expenses.
Self-Employed Filers: The 70-Cent Mileage Rate and Q1 Estimated Tax Due Today
Self-employed taxpayers and gig workers face a dual deadline today: the 2025 annual return and the first quarter 2026 estimated tax payment. The 2026 IRS standard mileage rate for business use is 70 cents per mile. If you drove for business in 2025, the rate that applied was set by the IRS for that year — confirm the 2025 rate on IRS.gov before filing.
Confirm your federal return or extension Form 4868 is submitted by April 15, 2026 to avoid failure-to-file penalties of 5% per month on unpaid tax *
Verify your Social Security Number and exact refund amount match IRS records before using the ‘Where’s My Refund’ tool at irs.gov *
Check that all W-2s, 1099s, and K-1s received by January 31, 2026 are accounted for and match the income figures on your return *
Review the 2026 updated tax brackets to confirm your withholding or estimated payments covered at least 90% of your 2026 tax liability or 100% of your 2025 liability to avoid underpayment penalties
If expecting a refund, consider updating your direct deposit banking details in IRS systems to receive funds up to 3 weeks faster than a paper check
If you owe a balance, arrange payment by April 15, 2026 even if filing an extension, since an extension grants extra time to file but not extra time to pay
Self-employed individuals deduct half of self-employment tax on Schedule 1, deduct health insurance premiums above the line, and can contribute to a SEP-IRA up to 25% of net self-employment income, with a 2026 cap of $70,000 (the defined contribution limit). SEP-IRA contributions for 2025 can be made until the extended return deadline — October 15, 2026 if you file Form 4868 today.
Nine States With No Income Tax: Your Refund Is Federal-Only
Residents of Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming owe no state income tax. If you live in one of these states, the refund you are tracking on IRS.gov/refunds is your entire tax refund — there is no separate state return to file. New Hampshire taxes interest and dividend income for some filers, though that tax has been phased out; confirm your specific situation with the state revenue department.
All other states have their own refund tracking tools. Most use a similar three-field lookup: Social Security number, filing status, and refund amount. State refunds are processed independently of the federal refund and often arrive on a different timeline.
The SSA announces the 2027 COLA in October 2026, and the IRS will publish 2027 inflation adjustments in a new Revenue Procedure expected in late October or November 2026 — those numbers will reset every bracket, deduction, and contribution limit discussed here.
