Not claiming the correct number of allowances generally impacts your tax withholding throughout the year, leading to either a larger tax refund or a larger tax bill when you file your annual tax return. It does not mean the money is forfeited.
Claiming "0" means more withheld. It reduces the take-home pay but possibly leads to a refund. Claiming "1" means less withheld. This option presents a larger paycheck but increases the risk of owing amounts at tax time.
Allowances are generally subject to payroll tax. The only allowances that are not wholly taxable are motor vehicle allowances, accommodation allowances and living away from home allowances.
If you're under the required filing threshold for your filing status, you might not have to file a tax return, but if you do, you could still get a refund if you qualify for certain credits. Learn more about the required filing threshold and why you might want to file either way.

Everyone, including students, has something called a Personal Allowance. This is the amount of money you're allowed to earn each tax year before you start paying Income Tax. For the 2025/26 tax year, the Personal Allowance is £12,570. If you earn less than this, you usually won't have to pay any Income Tax.
Using a reputable tax preparer – including certified public accountants, enrolled agents or other knowledgeable tax professionals – can also help avoid errors.
If you don't claim the tax-free threshold on your TFN Declaration, your employer will withhold tax from your entire income at a higher rate (as if you're not entitled to the threshold). However, you can still receive the benefit of the tax-free threshold when you lodge your annual tax return.
First, the IRS charges a 5% penalty per month on any tax due if your return is filed late. The penalty is capped at 25% of the tax owed. If the return is more than 60 days late, the minimum late-filing penalty for returns due in 2026 is $525 or 100% of the tax owed, whichever is less.

Getting your federal tax allowances wrong can carry consequences: Too Many Allowances (Under-Withholding): You'll take home more pay during the year but risk owing taxes and possibly penalties when filing. Too Few Allowances (Over-Withholding): More money is withheld, which often results in a larger refund.
The filing status that gives the biggest refund depends on your specific situation, including your income, deductions, and credits. Generally, “Married Filing Jointly” and “Head of Household” statuses offer more favorable tax rates and higher standard deductions, which can lead to a larger refund.
Failing to lodge is a criminal offence and once convicted by the court you could face additional fines and/or imprisonment for up to 12 months.
