Yes, you can generally claim tax relief or refunds for previous years, but it is typically limited to three years from the original filing deadline or two years from when the tax was paid, whichever is later IRS (.gov). If you did not file a return, you must do so within this period to claim a refund, otherwise, the funds are lost.

The IRS requires that deductions and credits be claimed in the tax year they apply. This means if you missed a deduction on last year's return, you generally cannot simply add it to this year's return. Instead, the proper way to correct the oversight is by filing an amended return for the prior year.
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.
The IRS 3-year rule generally refers to the statute of limitations for claiming a tax refund, which is typically 3 years from when you filed your original return or 2 years from when you paid the tax, whichever is later, for the IRS to process your claim. For an audit, the IRS generally has 3 years from the date your return was filed or due (whichever is later) to assess additional tax, though this can extend to 6 years if you significantly underreport income or omit foreign income.
If you need to make a change or adjustment on a return already filed, you can file an amended return. Use Form 1040-X, Amended U.S. Individual Income Tax Return, and follow the instructions.

Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.

It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
