Submit a new Form W-4 to your employer whenever you start a new job, or within 10 days of any life change that affects your taxes—such as marriage, divorce, having a child, or a significant income change. To ensure accurate withholding for the new year, it is recommended to review and update your W-4 early in the calendar year.
You generally complete Internal Revenue Service (IRS) Form W-4, Employee's Withholding Certificate, at the start of any new job. The form is crucial in determining your balance due or refund each tax season. You don't have to fill out a new Form W-4 every year as long as you have one on file with your employer.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
You change your W-4 anytime. For instance, you can adjust your paycheck withholding to reflect life changes like a new job, marriage, or new child. Adjusting your W-4 can help you avoid a surprise tax bill or possibly net a larger refund.
The late filing penalty is 5% of the additional taxes owed amount for every month (or fraction thereof) your return is late, up to a maximum of 25%. If you file more than 60 days after the due date, the minimum penalty is $525 (for tax returns required to be filed in 2026) or 100% of your unpaid tax, whichever is less.
If you owe tax and don't file on time (with extensions), there's also a penalty for not filing on time. The failure-to-file penalty is usually five percent of the tax owed for each month, or part of a month, that your return is late, up to a maximum of 25%.
You may request up to an additional 6 months to file your U.S. individual income tax return. There are three ways to request an automatic extension of time to file your return. You must request the extension of time to file by the due date of your return to avoid the penalty for filing late.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
Changing your W-4 withholding directly alters your take-home pay: more withholding means a smaller paycheck but a larger refund (or smaller bill) at tax time, while less withholding gives you more cash in each check but risks a tax bill or penalty later, balancing a bigger paycheck against a smaller refund. Adjustments usually take effect in one or two pay cycles, impacting how much federal income tax is deducted from each pay period based on your earnings and W-4 information, like filing status and credits/deductions.
Your employer is required to withhold income tax from your wages as if you are single with zero allowances if you do not submit a Form W-4.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
What is a 1099-K form? IRS Form 1099-K is a tax document that reports any payments you received through third-party networks like Venmo, PayPal, or Apple Pay. If you receive more than $20,000 in at least 200 transactions through these platforms, you'll likely get a 1099-K.
To get more money in your paycheck (less tax withheld), you can claim more dependents in Step 3, claim deductions for other income in Step 4(a), or claim other deductions in Step 4(b); conversely, to get a bigger refund (more tax withheld now), add an amount in Step 4(c) or Step 4(a). Use the IRS Tax Withholding Estimator to accurately calculate adjustments for your specific situation, ensuring you don't underpay taxes, and submit the updated W-4 to your employer.
If you chose to claim an exemption from your employer withholding taxes from your paycheck last year by filing a Form W-4, you'll need to re-file the form by this date. This date typically falls on February 15 each year.
- The wrong state withheld. We've seen this when employees are remote or when employees move. This can also happen if an employee works in a state but lives in a reciprocal state (such as an Indiana resident working in Kentucky). - State or city taxes not being remitted by the employer.
To fill out a W-4, you'll provide personal info (Step 1) and then complete Steps 2-4 only if they apply to you (multiple jobs, dependents, other income/deductions), using the IRS Estimator or worksheets for accuracy, and finally sign and date in Step 5 to tell your employer how much tax to withhold from your paycheck, affecting your refund or tax bill.
Wages, dividends, bank interest, and other income received and that was reported on an information return should be entered carefully. This includes any information needed to calculated credits and deductions.
For those who are terrified of extensions, remember that they're okay. Unless you file for extensions for years and years, they're not going to increase your chance of being audited, and they won't have any consequences if you pay your taxes on time.
If you file taxes after the October 15 extension deadline, the IRS will assess penalties and interest, primarily a failure-to-file penalty (5% per month, max 25%), plus a separate failure-to-pay penalty (0.5% per month) and daily interest on the unpaid taxes, though you can request penalty abatement for reasonable cause like natural disasters. The October deadline is for filing, not paying; if you owe, payment was due in April, so you'll likely face both penalties and interest until you file and pay, but you won't be penalized if you're due a refund.
A reasonable excuse is something that stopped you meeting a tax obligation for a valid reason, for example: your partner or another close relative died shortly before the tax return or payment deadline. you had an unexpected stay in hospital that prevented you from dealing with your tax affairs.
