Poor fire habits, atmospheric rivers, flooding, and mudslides are threats to Californians on a regular basis. In addition to the physical impacts, these disasters can place unexpected strains on your finances, making tax deadlines and relief options particularly significant.

For taxpayers in federally declared disaster areas, the IRS may offer filing extensions, payment relief, and special tax provisions. If you are a homeowner, individual, or business, it is important to be aware of these options to help you make solid financial decisions during recovery.

How IRS Disaster Tax Relief Works


If a federal disaster declaration includes certain California counties, the IRS may delay the filing and payment deadlines for affected taxpayers for certain tax deadlines. Eligible obligations and the relief period will vary by disaster announcement. To manage business payroll tax problems, you must look for an experienced professional.

Relief may be offered in the form of extra time for making federal income tax returns, payments of qualifying federal taxes, and certain business tax deadlines as appropriate. Some penalties for postponed obligations may also be waived for eligible taxpayers.

Note: Not everyone in California is eligible for relief. Eligibility is typically based on the affected location, declaration of the disaster, and applicable IRS announcement. Visit the IRS Disaster Relief page for up-to-date deadlines and counties eligible for disaster relief.

What is the Meaning of Casualty Loss Deductions?


The usual definition of casualty loss is a sudden, unusual, and unexpected event that causes destruction, damage, or loss to property, like a flood or a forest fire. However, under federal tax law, personal casualty losses can only be claimed in certain situations.

Federal casualty loss deductions (with certain exceptions) are normally limited to losses from property used for personal, family, or household reasons that are caused by a federally declared disaster. The rules may be different for business and income-producing property.

The deductible amount doesn't always match the total repair costs or insurance claim. Usually, the adjusted basis of the property, the loss in fair market value, and insurance or other reimbursements are the factors taken into account when doing the calculations.

Taxpayers should also remember that there are state tax issues in California that may vary from the federal issues, depending upon the facts and applicable state law. Hire an expert if you are looking for tax relief services in San Diego.

If a Disaster Has Occurred, There Are Some Tips That Can Help:


·        Document the damage: Take photographs of damaged property, damaged items, and the conditions of the repairs prior to cleanup were safe.

·        Store financial documents: Save contractor quotes, receipts, insurance documents, and disaster-related expenses.

·        Check insurance payments: Insurance payments should be taken into consideration when determining any potential deductible loss.

·        Review official deadlines: Go to IRS.gov and look for disaster tax relief updates about your county. Look for a tax professional (similar to an attorney for payroll issues) and enjoy the benefits.

·        Continue filing compliance: An extension to file will not automatically extend the same time period to pay taxes unless the extension happens to be in line with disaster relief.

·        Seek expert advice: A tax expert can be of great assistance in determining eligibility, in determining losses, and in differentiating between federal and California requirements.

Can You Amend a Previous Tax Return?


If you are eligible, the disaster loss may be claimed on a previous year's return, or on the year of the disaster if the law allows you to claim a disaster loss on that year's return. The decision may impact when a potential refund is received, and may also correspond to the total amount of taxes due, so it's advisable for taxpayers to check the options before submitting their tax returns.

Natural disasters can have a lasting impact on livelihoods beyond the initial hazard. Knowing what constitutes an IRS extension, keeping good records of losses, and establishing eligibility for the extension can help California residents prevent avoidable tax complications.

Disaster relief laws are subject to change and have time limits, so check the latest guidance before taking any action. Rather than making assumptions or promises about the results you can achieve, professional tax assistance can help you do an analysis of all of your options.
