Question 1

What is the 2025 federal income tax deadline (for returns filed in 2026)?

Accepted Answer

The IRS deadline for filing 2025 federal income tax returns is April 15, 2026. If you need more time, you can file Form 4868 for an automatic 6-month extension, moving your deadline to October 15, 2026. However, an extension to file does NOT extend the time to pay — any taxes owed must still be paid by April 15 to avoid underpayment penalties (currently 8% per annum). If April 15 falls on a weekend or holiday, the deadline moves to the next business day.

Question 2

What are the 2025 federal income tax brackets (filed in 2026)?

Accepted Answer

For 2025 tax year (filed in 2026): 10% on income up to $11,925 (single) / $23,850 (married filing jointly); 12% on $11,926-$48,475 / $23,851-$96,950; 22% on $48,476-$103,350 / $96,951-$206,700; 24% on $103,351-$197,300 / $206,701-$394,600; 32% on $197,301-$250,525 / $394,601-$501,050; 35% on $250,526-$626,350 / $501,051-$751,600; 37% on over $626,350 / $751,600. These brackets were inflation-adjusted from 2024.

Question 3

What is the 2025 standard deduction?

Accepted Answer

For tax year 2025: Single filers — $15,000 (up from $14,600 in 2024); Married Filing Jointly — $30,000 (up from $29,200); Head of Household — $22,500 (up from $21,900). If you are 65 or older or blind, you get an additional $1,550 (single) or $1,250 per qualifying condition (MFJ). Most taxpayers (approximately 90%) take the standard deduction rather than itemising.

Question 4

How does the Child Tax Credit work in 2025?

Accepted Answer

The Child Tax Credit for 2025 is $2,000 per qualifying child under age 17. Up to $1,700 of the credit is refundable (Additional Child Tax Credit). The credit begins to phase out at $200,000 of AGI for single filers and $400,000 for married filing jointly. To be a qualifying child, the child must be under 17 at December 31, 2025, a US citizen, and live with you more than half the year.

Question 5

What is the Earned Income Tax Credit (EITC) for 2025?

Accepted Answer

The EITC is a refundable credit for low-to-moderate income workers. Maximum 2025 credits: no children — $649 (max income ~$19,104 single); 1 child — $4,328 (max income ~$46,560 single); 2 children — $7,152 (max income ~$52,918 single); 3+ children — $8,046 (max income ~$56,838 single). Income limits are higher for married filing jointly. The EITC is fully refundable — you can receive it even if you owe no tax.

Question 6

What are the penalties for filing or paying late?

Accepted Answer

Failure-to-file penalty: 5% of unpaid taxes per month (or part of month), up to 25% maximum. Failure-to-pay penalty: 0.5% per month, up to 25%. If both apply, the failure-to-file penalty is reduced by the failure-to-pay penalty. The current underpayment rate (2026) is the federal short-term rate plus 3 percentage points (approximately 8%). If you are due a refund, there is NO penalty for filing late — but you cannot claim your refund until you file.
