Does your business hold on to all of its paper records? Many individuals and businesses hold onto paper and digital records indefinitely — just in case. But it can become burdensome to securely store years of financial records. Here’s some guidance to help minimize recordkeeping overload.

Business Recordkeeping

Here are some best practices for records used to substantiate a business’s payroll, income and sales tax filings.

Employee records. Keep personnel records for three years after an employee has been terminated. Also maintain records that support employee earnings for at least four years. This timeframe should cover various state and federal requirements. (However, don’t throw away records that might involve unclaimed property, such as a final paycheck not claimed by a former employee.)

Timecards specifically must be kept for at least three years if your business engages in interstate commerce and is subject to the Fair Labor Standards Act. However, it’s a best practice for all businesses to keep the files for several years in case questions arise.

Employment tax records. Keep these for four years from the date the tax was due or the date it was paid, whichever is longer.

Travel and entertainment records. For travel and transportation expenses supported by mileage logs and other receipts, keep supporting documents for the three-year statute of limitations.

Sales tax returns. State regulations vary. For example, New York generally requires sales tax records to be retained for three years, while California requires four years, and Arkansas, six. Check with your tax advisor.

Business property. Records used to substantiate the cost and deductions (such as depreciation, amortization and depletion) associated with business property must be maintained to determine the basis and gain (or loss) on the sale. Keep these for as long as you own the asset, plus seven years, according to IRS guidelines.

Personal Tax Records

In order to prove to the IRS that you actually filed your taxes, most tax advisors recommend that you hold onto copies of your finished tax returns indefinitely. Even if you don’t keep the returns indefinitely, you should hang onto them for at least six years after they’re due or filed, whichever is later.

It’s a good idea to keep records that support items shown on your individual tax return until the statute of limitations runs out — generally, three years from the due date of the return or the date you filed, whichever is later. Examples of supporting documents include canceled checks and receipts for alimony payments, charitable contributions, mortgage interest payments and retirement plan contributions. You can also file an amended return on Form 1040X during this timeframe if you missed a deduction, overlooked a credit or misreported income.

If you’d like to purge some old paperwork, you can generally throw out records for the 2014 tax year, for which you filed a return in 2015.

However, you’re not necessarily safe from an IRS audit after three years. There are some exceptions to the three-year rule. For example, if the IRS has reason to believe your income was understated by 25% or more, the statute of limitations for an audit increases to six years. Or, if there’s suspicion of fraud or you don’t file a tax return at all, there is no time limit for the IRS to launch an inquiry.

In addition, if you have records that support figures affecting multiple years, such as carryovers of charitable deductions, net operating loss carrybacks or carryforwards, or casualty losses, those need to be saved until the deductions no longer have effect, plus seven years, according to IRS instructions.

In some cases when taxpayers get more than the usual three years to file an amended return, you have up to seven years to take deductions for bad debts or worthless securities. So don’t toss out records that could result in refund claims for those items!

Important note: Keep in mind that these guidelines are all geared toward complying with federal tax obligations. Check with your tax advisor to learn how long you should keep your state tax records. Some states have different statutes of limitation for auditing tax returns.

Other Recordkeeping Guidelines for Individuals

If your filing cabinet contains more than just tax information, such as some essential records; birth and death certificates; marriage licenses; divorce decrees; Social Security cards and military discharge papers — those should be kept indefinitely. Other kinds of records can eventually be purged.

Here’s some guidance to help individuals decide whether to shred or save other types of financial records.

Bills and receipts.  In general, it’s OK to shred most bills — like the phone bill or credit card statement — when your payment clears your bank account or at year end. For most people, old bills and receipts make up the bulk of what’s in their files.

However, if a bill or receipt supports an item on your tax return, follow the tax guidance above. Or if you purchase a big-ticket item — like jewelry, furniture or a computer — keep the bill for as long as you have the item. You never know if you’ll need to substantiate an insurance claim in the event of loss or damage.

Securities. You must maintain detailed records of purchases and sales to accurately report taxable events involving stocks and bonds. These records should include dates, quantities, prices, dividend reinvestment and investment expenses, such as broker fees. Keep these records for as long as you own the investments, plus the statute of limitations on the relevant tax returns.

IRAs. The IRS requires you to keep copies of Forms 8606, 5498 and 1099-R until all the money is withdrawn from your IRAs. With the introduction of Roth IRAs, it’s more important than ever to hold onto all IRA records pertaining to contributions and withdrawals in case you’re ever questioned.

Treat IRA records with the same rules as securities if an account is closed. Don’t dispose of any ownership documentation until the statute of limitations expires.

Real estate records. These records should be kept for as long as you own the property, plus three years after you dispose of it and report the transaction on your tax return. Throughout ownership, keep records of the purchase, as well as receipts for home improvements, relevant insurance claims and documents relating to refinancing. These help prove your adjusted basis in the home, which is needed to figure any taxable gain at the time of sale, or to support calculations for rental property or home office deductions.

Ask Before You Shred

You don’t want to be caught empty-handed if an IRS or state tax auditor contacts you, so reach out to Filler & Associates or your tax advisor before you clear your file cabinets of old financial records.
