Forgetting to file a required gift tax return (Form 709) can lead to IRS penalties, interest on unpaid taxes, and an indefinite extension of the audit statute of limitations. While no penalty usually applies if no tax is owed, failures can result in fees of 5% per month (up to 25%) of the tax due.
If you make a taxable gift to someone else, a gift tax return needs to be filed. If you fail to do this, penalties may apply. If you don't file the gift tax return as you should, you could be responsible for the amount of gift tax due as well as 5% of the amount of that gift for every month that the return is past due.
The failure to file a required gift tax return may result in a penalty of 5% per month of the tax due, up to 25%. Bear in mind, though, that you might file a gift tax return even if you're technically not required.
The IRS primarily learns about large gifts when you file Form 709, the Gift Tax Return, for amounts exceeding the annual exclusion (e.g., $19,000 per person in 2025). They can also discover gifts through third-party reporting (banks reporting large cash transfers), audits of your estate, or by matching transactions to public records, especially for significant asset transfers like property, which might trigger property tax reassessments.
It kicks in only after exceeding the lifetime exclusion limit of $13.99 million for tax year 2025, emphasizing that this is a cumulative limit over the taxpayer's lifetime. The annual reporting threshold is $19,000 in 2025, which requires gifts above this amount to be reported to the IRS via Form 709.
Yes, you can give your son $100,000 tax-free in 2025 by utilizing the annual gift tax exclusion and your lifetime exemption, but you'll need to report the gift to the IRS on Form 709 since it exceeds the $19,000 annual limit, though you won't pay tax unless you exceed your much larger $13.99 million lifetime gift/estate tax exemption. The gift is considered yours (the giver) for tax purposes, not your son's.
HMRC can impose financial penalties when gifts are not declared correctly and the Executors may be liable to pay these penalties themselves. However, it is not always the Executors who are responsible for the payment of the penalties.
What Can Trigger a Gift or Estate Tax Audit? Here are some of the common factors that can lead to gift or estate tax audits: Total estate and gift value: Generally speaking, gift and estate tax returns are more likely to be audited when there are taxes owed and the size of the transaction or estate is relatively large.
Three elements must be met for a gift to be legally valid:
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.
If you don't file taxes when required, the IRS imposes significant penalties and interest, starting with a 5% late-filing penalty (up to 25% of tax owed), plus a failure-to-pay penalty (0.5% per month), and interest on the total amount due, which can lead to wage garnishment, tax liens on property, seizure of assets, and even criminal charges in severe cases, though the primary consequences are financial penalties and collection actions. If you're owed a refund, there are no penalties for filing late, but you must file to claim it.
When you disclose the value of your gift on a gift tax return, Form 709 , it triggers a three-year statute of limitations. This means the IRS has three years to audit your gift, after which they typically can no longer challenge the reported value of the gifts, unless there is substantial omission or fraud.
You, as the recipient of the gift, generally do not have to pay the gift tax. The person who does the gifting will file the gift tax return, if necessary, and pay any gift tax due. If the donor does not pay the gift tax, the IRS may try to collect it from you.
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.
Over the past decade, just under 1% of total gift tax returns and roughly 10% of estate tax returns have been audited, but gift and estate taxpayers can expect an increase in the IRS scrutiny of these filings with the additional funding allocated to enforcement efforts.
The IRS primarily learns about large gifts when you file Form 709, the Gift Tax Return, for amounts exceeding the annual exclusion (e.g., $19,000 per person in 2025).

But once a gift is given, it generally becomes the legal property of the recipient, making it difficult for the donor to reclaim it without the recipient's consent. The donor no longer owns the property; it is fully vested in the recipient.
HMRC doesn't track gifts live, but they get curious when someone dies, and the executor has to declare all gifts made in those seven years that go beyond certain exemptions. For 2025/26, the IHT threshold (Nil Rate Band) is £325,000, and anything above that, including taxable gifts, faces a 40% tax, per GOV.UK.
Giving a generous gift should feel good—not trigger a letter from the IRS. But if you don't file your gift tax return on time, you could be penalized up to 100% of the tax amount. The IRS requires that you file Form 709, which is the tool the IRS uses to track lifetime gifting.
Yes, you can gift your son $100,000, but since it's over the 2025 annual exclusion of $19,000, you'll need to file a gift tax return (Form 709), though you likely won't owe taxes unless you've already used up your large lifetime exemption (over $13.99 million in 2025). Your son pays no tax on the gift, but you, as the giver, must report the amount exceeding the annual limit, which counts against your lifetime exemption.
Bottom Line. The exclusions to the federal gift tax mean you can probably give $50,000 to each of your children without owing any tax. Since a gift of that size is more than the current annual exclusion of $19,000, you would have to file Form 709 to report the gift to the IRS.
