Even small amounts of unreported income can cause problems later if the IRS receives matching information.<\/li>\n\n\n\n<li><strong>Overlooking valuable credits and deductions:&nbsp;<\/strong>Missing credits is another frequent tax mistake.

Not to mention, each state has its own tax rules, income thresholds, and requirements.&nbsp;Multi-state return mistakes usually involve filing in the wrong state, missing a required return, or allocating income incorrectly.&nbsp;Multi-state filing mistakes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Not filing a return in every state where it\u2019s required, especially if you work out of state or move during the year<\/li>\n\n\n\n<li>Reporting income incorrectly when it was earned in more than one state<\/li>\n<\/ul>\n\n\n\n<p>When you have these types of errors, you might receive a notice from a state tax agency asking about missing income or a return that wasn\u2019t filed.&nbsp;You can lower the risk of these mistakes by keeping good records throughout the year. Track where you worked, especially if your job or location changed.&nbsp;<\/p>\n\n\n\n<p>Because multi\u2011state tax returns involve more rules and higher likelihood of error, they\u2019re often a sign it\u2019s time to get expert help whether that\u2019s with an H&amp;R Block&nbsp;<a href=\"https:\/\/www.hrblock.com\/tax-offices\/our-tax-pros\">tax professional<\/a>&nbsp;or help with&nbsp;<a href=\"https:\/\/www.hrblock.com\/online-tax-filing\/\">online tax preparation<\/a>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What W\u20114 withholding mistakes can affect your refund?<\/h2>\n\n\n\n<p>Withholding mistakes can impact your tax refund.&nbsp;If your withholding is off, you could owe taxes or receive a smaller refund than expected.<\/p>\n\n\n\n<p>When your W-4 form withholding doesn\u2019t account for all household income or it is outdated, you may run the risk of not withholding the right amount of taxes each pay period. Big life changes\u2014like getting married, having a child, or starting a new or second job\u2014can change how much tax your employer should withhold. To avoid this, review your withholding and your spouse\u2019s withholding at least once a year or after significant life changes.

Minor issues\u2014like math errors or missing information\u2014are often corrected by the IRS and may simply delay your refund. More serious&nbsp;tax filing errors, such as underreporting income or claiming credits you don\u2019t qualify for, can trigger IRS notices, including an underreporter inquiry, or result in penalties and interest.<\/p>\n\n\n\n<p>To reduce risk, review your return carefully before filing and use e\u2011filing tools that automatically check for errors. If you receive an IRS notice, responding accurately and on time is key.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How can I fix a mistake after filing taxes?<\/h3>\n\n\n\n<p>The IRS often fixes simple math errors or missing forms on its own and will send you a notice if it makes a correction. However, if the mistake changes your income, deductions, credits, or filing status\u2014and affects how much tax you owe or your refund\u2014you should file an amended return using Form 1040-X. Correcting the error promptly can help reduce penalties and interest if additional tax is due.<\/p>\n\n\n\n<p>If you\u2019re unsure whether or not you should amend your return, consult&nbsp;<a href=\"https:\/\/www.hrblock.com\/tax-offices\/our-tax-pros\/\">our tax professionals<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What tax mistakes trigger IRS audits?<\/h3>\n\n\n\n<p>Certain&nbsp;common tax filing mistakes&nbsp;are more likely to draw IRS attention. These include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reporting less income than what the IRS has on record<\/li>\n\n\n\n<li>Claiming credits or deductions you don\u2019t qualify for<\/li>\n<\/ul>\n\n\n\n<p>The IRS often finds these problems through automated matching systems, not full audits. This usually leads to a notice in the mail. Reporting your income correctly and keeping good records are the best ways to protect yourself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What mistakes are common when filing self\u2011employed taxes?<\/h3>\n\n\n\n<p>Self\u2011employed filers frequently make&nbsp;tax filing mistakes&nbsp;related to income reporting and expense deductions. Common issues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Not reporting all non\u2011W\u20112 income<\/li>\n\n\n\n<li>Overestimating or misclassifying business expenses, like claiming non-qualifying or incorrectly categorized personal expenses as deductions<\/li>\n\n\n\n<li>Treating a hobby as a business<\/li>\n<\/ul>\n\n\n\n<p>For example, a freelancer who omits income reported on a 1099 may receive an underreporter inquiry.
