The Pros and Cons of Filing a Tax Extension
An extension is your way of asking the Internal Revenue Service for additional time to file your tax return. The IRS will automatically grant you an additional six months to file your return. An extension basically extends the filing deadline for personal tax returns from April 17 to October 15. Businesses can also request an extension, which pushes their deadline to September 15.
Note well: While an extension gives you extra time to file your return, an extension does not give you extra time to pay your tax. Payments are still due by April 17, 2018 for the year 2017. But an extension can help reduce your penalties if you cannot afford to pay in full by the deadline.
The Pros of Filing an Extension
- Having 6 Extra Months to Finish up Your Tax Return: Having extra time to finish your return is often necessary, especially if you are still waiting for tax documents to arrive in the mail or you need additional time to organize your tax deductions. Extensions also provide extra time to file your gift tax return.
- Helps Reduce Late Penalties: There are two basic penalties the IRS typically imposes: a late filing penalty of 5 percent per month on any tax due plus a late payment penalty of half a percent per month. If you file an extension and then file by the extended deadline of October 15, you'll avoid the 5 percent per month late filing penalty. If you file after October 15, the late filing penalty will begin from October 15, which creates a deferral on this penalty.
- Preserves Your Tax Refunds If You File After the Extended Deadline: Some people end up filing several years late, and there's a three-year deadline for receiving a refund check from the IRS. This three-year statute of limitations begins on the original filing deadline (April 17, 2018, for the year 2017). But with an extension, the refund statute of limitations is also extended by six months, which can preserve the ability of taxpayers to receive their federal tax refund even if they get behind in submitting their tax return.
- Provides Extra Time for Self-Employed Persons to Fund a Retirement Plan: Self-employed persons may want to fund a SEP-IRA, solo 401(k) or SIMPLE-IRA plan for themselves. Filing an extension provides these taxpayers with an extra six months to fund their retirement plan. Note: solo 401(k) and SIMPLE plans need to be set up during the tax year, but actually funding the plan can occur as late as the extended deadline for the previous tax year. With a SEP-IRA, however, entrepreneurs can open and fund a SEP-IRA for the previous year by the extended deadline as long as they filed an extension.
- Additional Time to Recharacterize an IRA Contribution: As long as your IRA is funded by the April deadline, you can change the nature of the IRA by the October extended deadline. Essentially, you can turn your traditional IRA contribution into a Roth IRA, or a Roth IRA contribution into a traditional IRA contribution. This is helpful if you're not sure if your eligible for one type of IRA. You can even use this provision to recharacterize a Roth conversion back to a traditional IRA.
- Provides Additional Time to Make Various Elections on Your Tax Return: There are a wide variety of decisions that can be made on the tax return, such as deciding whether to equipment or take a , and whether to . Those decisions must be made when the tax return is filed. Filing an extension gives you extra time to make those decisions.
- Filing an Extension Can Improve the Accuracy of Your Return: There's an inevitable rush to get tax returns finished by the deadline, and taxpayers and accountants alike can make mistakes when rushing. With an extension, this gives you and your accountant extra time to go over the return and make sure everything is complete before sending in the return.
- Extensions Can Help Reduce Your Tax Preparation Fees: Some accountants raise their fees in the weeks leading up to the deadline, only to drop their fees during the slow spring and summer months. Price-sensitive taxpayers may be able to save money by shifting their tax preparation to a time when their accountant is charging a lower fee.
The Cons of Filing an Extension
- Extra Time to File Doesn't Mean Extra Time to Pay: An extension will give you extra time to file your return, but any tax is still due by the original deadline. An extension can help reduce penalties, but any outstanding balance will still be charged a late payment penalty (0.5 percent per month) and interest (right now at 3 percent annually).
- Some People Aren't Eligible for Extensions: Taxpayers who were approved for an offer in compromise must file by the April deadline during their five-year probationary period. If you don't file by the April deadline, the IRS can revoke your offer-in-compromise and re-instate the original amount you owed.
- No Extra Time to Fund an IRA: Contributions to a Traditional IRA and/or Roth IRA are due by the original April deadline.
- No Extra Time for Married Couples to Switch From Joint to Separate Returns: Married taxpayers who filed jointly by the April deadline can, if they wish, switch to the married-filing-separately status by April 18 by amending their tax return.
- No Extra Time to Make the Mark-To-Market Election for Professional Traders: Joe Kristan, CPA, explains. "If you qualify as a 'trader,' April  is your deadline for choosing whether to make the 'mark-to-market election' on your trading positions."
Be Sure to File a Return, Even If You Don't Think You Need To
I've only seen this happen once, but I still want you to know about it. If you file an extension, the IRS might think you need to file a tax return. If you end up not filing a tax return (perhaps because you don't meet the filing requirements), the IRS might get confused and ask you to file a return anyway, on the presupposition that you filed an extension to ask for additional time to file.
