A tax shelter is a legal strategy or investment designed to reduce taxable income and, consequently, the amount of taxes a company owes to the government.

Tax shelters are legal strategies that can decrease or defer a taxpayer’s tax liability. They come in a variety of different forms and methods and can offer significant benefits if used properly.
A tax shelter is a way to shield assets and reduce or defer taxes. Tax shelters are completely legal, and both individuals and businesses can use them. Remember, no one can avoid taxes — doing so is tax evasion and a federal crime — but tax shelters can help individuals minimize them legally. There’s a difference.
The most obvious tax shelter advantages are that they can reduce your tax bill or defer tax payments to a later time. With certain tax shelters, creditors can’t access the money you put into them. Also, tax shelters are available to just about anyone. They range in complexity from simple strategies like taking business deductions on your tax return to sophisticated investing in the capital market.
While tax shelters can offer significant benefits, they also come with risks. Business owners want to be sure they’re not crossing over the line from tax avoidance to tax evasion. It’s also wise to consult with professionals who can provide advice on the process, particularly if an advanced strategy is involved. For example, foreign investments might allow someone to apply the foreign tax credit to reduce their U.S. tax bill. That said, creating an offshore company for funneling income to avoid U.S. taxes could land the business owner in prison.
Another potential disadvantage of using tax shelters is that they can limit a business owner’s access to their money. Certain tax shelters have penalties if a withdrawal is made. Retirement accounts are a great example of this; if someone pulls money out of their 401(k) (tax-sheltered funds) before they turn 59½, they’ll be penalized.
Tax shelters come in two main forms: tax deferral and tax reduction. Here are a few different examples of how tax shelters can defer or reduce taxes.
Tax-deferred retirement plans are commonly used tax shelters. Employer-sponsored 401(k)s, Individual Retirement Accounts (IRAs), Roth 401(k)s, and Roth IRAs are all vehicles that allow account holders to defer taxes on the income they contribute.
When someone claims deductions on their tax return, they’re using a tax shelter. Deductions like charitable donations, business expenses, home office expenses, and similar categories are all ways to reduce taxable income.
Tax credits are another form of tax sheltering. Credits are a dollar-for-dollar reduction of the taxes you owe. Taxpayers can get credits for certain types of purchases and investments.
“Tax havens” are another form of tax shelter. A tax haven is a place that has lower business or personal income tax rates. This can be a state or a foreign country. For example, Delaware is a tax shelter state for businesses because there’s no sales tax. Companies or individuals can keep assets in those tax havens and benefit from their favorable tax treatment.
The tax shelter definition is simple but encompasses a lot. With a properly implemented tax shelter, a taxpayer can either lower or defer their taxes. Financial professionals like accountants, tax lawyers, and financial advisors can ensure that the tax shelter used won’t get the taxpayer into legal trouble.
