Accounting Methods(p12)

For Use in Tax Year 2013
rule
An accounting method is a set of rules used to determine when and how income and expenses are reported. Your accounting method includes not only the overall method of accounting you use, but also the accounting treatment you use for any material item.
You choose an accounting method for your business when you file your first income tax return that includes a Schedule C for the business. After that, if you want to change your accounting method, you must generally get IRS approval. See Change in Accounting Method, later.
taxmap/pubs/p334-008.htm#en_us_publink1000313235

Kinds of methods.(p12)

For Use in Tax Year 2013
rule
Generally, you can use any of the following accounting methods.
You must use the same accounting method to figure your taxable income and to keep your books. Also, you must use an accounting method that clearly shows your income.
taxmap/pubs/p334-008.htm#en_us_publink1000313236

Business and personal items.(p12)

For Use in Tax Year 2013
rule
You can account for business and personal items under different accounting methods. For example, you can figure your business income under an accrual method, even if you use the cash method to figure personal items.
taxmap/pubs/p334-008.htm#en_us_publink1000313237

Two or more businesses.(p12)

For Use in Tax Year 2013
rule
If you have two or more separate and distinct businesses, you can use a different accounting method for each if the method clearly reflects the income of each business. They are separate and distinct only if you maintain complete and separate books and records for each business.
taxmap/pubs/p334-008.htm#en_us_publink1000313238

Cash Method(p12)

For Use in Tax Year 2013
rule
Most individuals and many sole proprietors with no inventory use the cash method because they find it easier to keep cash method records. However, if an inventory is necessary to account for your income, you must generally use an accrual method of accounting for sales and purchases. For more information, see Inventories, later.
taxmap/pubs/p334-008.htm#en_us_publink1000313240

Income(p12)

For Use in Tax Year 2013
rule
Under the cash method, include in your gross income all items of income you actually or constructively receive during your tax year. If you receive property or services, you must include their fair market value in income.
taxmap/pubs/p334-008.htm#en_us_publink1000313241

Example.(p12)

On December 30, 2012, Mrs. Sycamore sent you a check for interior decorating services you provided to her. You received the check on January 2, 2013. You must include the amount of the check in income for 2013.
taxmap/pubs/p334-008.htm#en_us_publink1000313242

Constructive receipt.(p12)

For Use in Tax Year 2013
rule
You have constructive receipt of income when an amount is credited to your account or made available to you without restriction. You do not need to have possession of it. If you authorize someone to be your agent and receive income for you, you are treated as having received it when your agent received it.
taxmap/pubs/p334-008.htm#en_us_publink1000313243

Example.(p13)

Interest is credited to your bank account in December 2013. You do not withdraw it or enter it into your passbook until 2014. You must include it in your gross income for 2013.
taxmap/pubs/p334-008.htm#en_us_publink1000313244
Delaying receipt of income.(p13)
You cannot hold checks or postpone taking possession of similar property from one tax year to another to avoid paying tax on the income. You must report the income in the year the property is received or made available to you without restriction.
taxmap/pubs/p334-008.htm#en_us_publink1000313245

Example.(p13)

Frances Jones, a service contractor, was entitled to receive a $10,000 payment on a contract in December 2013. She was told in December that her payment was available. At her request, she was not paid until January 2014. She must include this payment in her 2013 income because it was constructively received in 2013.
taxmap/pubs/p334-008.htm#en_us_publink1000313246
Checks.(p13)
Receipt of a valid check by the end of the tax year is constructive receipt of income in that year, even if you cannot cash or deposit the check until the following year.
taxmap/pubs/p334-008.htm#en_us_publink1000313247

Example.(p13)

Dr. Redd received a check for $500 on December 31, 2013, from a patient. She could not deposit the check in her business account until January 2, 2014. She must include this fee in her income for 2013.
taxmap/pubs/p334-008.htm#en_us_publink1000313248
Debts paid by another person or canceled.(p13)
If your debts are paid by another person or are canceled by your creditors, you may have to report part or all of this debt relief as income. If you receive income in this way, you constructively receive the income when the debt is canceled or paid. For more information, see Canceled Debt under Kinds of Income in chapter 5.
taxmap/pubs/p334-008.htm#en_us_publink1000313250

Repayment of income.(p13)

For Use in Tax Year 2013
rule
If you include an amount in income and in a later year you have to repay all or part of it, you can usually deduct the repayment in the year in which you make it. If the amount you repay is over $3,000, a special rule applies. For details about the special rule, see Repayments in chapter 11 of Publication 535, Business Expenses.
taxmap/pubs/p334-008.htm#en_us_publink1000313251

Expenses(p13)

For Use in Tax Year 2013
rule
Under the cash method, you generally deduct expenses in the tax year in which you actually pay them. This includes business expenses for which you contest liability. However, you may not be able to deduct an expense paid in advance or you may be required to capitalize certain costs, as explained later under Uniform Capitalization Rules.
taxmap/pubs/p334-008.htm#en_us_publink1000313252

Expenses paid in advance.(p13)

For Use in Tax Year 2013
rule
You can deduct an expense you pay in advance only in the year to which it applies.
taxmap/pubs/p334-008.htm#en_us_publink1000313253

Example.(p13)

You are a calendar year taxpayer and you pay $1,000 in 2013 for a business insurance policy effective for one year, beginning July 1. You can deduct $500 in 2013 and $500 in 2014.
taxmap/pubs/p334-008.htm#en_us_publink1000313254

Accrual Method(p13)

For Use in Tax Year 2013
rule
Under an accrual method of accounting, you generally report income in the year earned and deduct or capitalize expenses in the year incurred. The purpose of an accrual method of accounting is to match income and expenses in the correct year.
taxmap/pubs/p334-008.htm#en_us_publink1000313255

Income—General Rule(p13)

For Use in Tax Year 2013
rule
Under an accrual method, you generally include an amount in your gross income for the tax year in which all events that fix your right to receive the income have occurred and you can determine the amount with reasonable accuracy.
taxmap/pubs/p334-008.htm#en_us_publink1000313256

Example.(p13)

You are a calendar year accrual method taxpayer. You sold a computer on December 28, 2013. You billed the customer in the first week of January 2014, but you did not receive payment until February 2014. You must include the amount received for the computer in your 2013 income.
taxmap/pubs/p334-008.htm#en_us_publink1000313257

Income—Special Rules(p13)

For Use in Tax Year 2013
rule
The following are special rules that apply to advance payments, estimating income, and changing a payment schedule for services.
taxmap/pubs/p334-008.htm#en_us_publink1000313258

Estimated income.(p13)

For Use in Tax Year 2013
rule
If you include a reasonably estimated amount in gross income, and later determine the exact amount is different, take the difference into account in the tax year in which you make the determination.
taxmap/pubs/p334-008.htm#en_us_publink1000313259

Change in payment schedule for services.(p13)

For Use in Tax Year 2013
rule
If you perform services for a basic rate specified in a contract, you must accrue the income at the basic rate, even if you agree to receive payments at a lower rate until you complete the services and then receive the difference.
taxmap/pubs/p334-008.htm#en_us_publink1000313260

Advance payments for services.(p13)

For Use in Tax Year 2013
rule
Generally, you report an advance payment for services to be performed in a later tax year as income in the year you receive the payment. However, if you receive an advance payment for services you agree to perform by the end of the next tax year, you can elect to postpone including the advance payment in income until the next tax year. However, you cannot postpone including any payment beyond that tax year.
For more information, see Advance Payment for Services under Accrual Method in Publication 538. That publication also explains special rules for reporting the following types of income.
taxmap/pubs/p334-008.htm#en_us_publink1000313261

Advance payments for sales.(p14)

For Use in Tax Year 2013
rule
Special rules apply to including income from advance payments on agreements for future sales or other dispositions of goods you hold primarily for sale to your customers in the ordinary course of your business. If the advance payments are for contracts involving both the sale and service of goods, it may be necessary to treat them as two agreements. An agreement includes a gift certificate that can be redeemed for goods. Treat amounts that are due and payable as amounts you received.
You generally include an advance payment in income for the tax year in which you receive it. However, you can use an alternative method. For information about the alternative method, see Publication 538.
taxmap/pubs/p334-008.htm#en_us_publink1000313262

Expenses(p14)

For Use in Tax Year 2013
rule
Under an accrual method of accounting, you generally deduct or capitalize a business expense when both the following apply.
  1. The all-events test has been met. The test has been met when:
    1. All events have occurred that fix the fact of liability, and
    2. The liability can be determined with reasonable accuracy.
  2. Economic performance has occurred.
taxmap/pubs/p334-008.htm#en_us_publink1000313263

Economic performance.(p14)

For Use in Tax Year 2013
rule
You generally cannot deduct or capitalize a business expense until economic performance occurs. If your expense is for property or services provided to you, or for your use of property, economic performance occurs as the property or services are provided or as the property is used. If your expense is for property or services you provide to others, economic performance occurs as you provide the property or services. An exception allows certain recurring items to be treated as incurred during a tax year even though economic performance has not occurred. For more information on economic performance, see Economic Performance under Accrual Method in Publication 538.
taxmap/pubs/p334-008.htm#en_us_publink1000313264

Example.(p14)

You are a calendar year taxpayer and use an accrual method of accounting. You buy office supplies in December 2013. You receive the supplies and the bill in December, but you pay the bill in January 2014. You can deduct the expense in 2013 because all events that fix the fact of liability have occurred, the amount of the liability could be reasonably determined, and economic performance occurred in that year.
Your office supplies may qualify as a recurring expense. In that case, you can deduct them in 2013 even if the supplies are not delivered until 2014 (when economic performance occurs).
taxmap/pubs/p334-008.htm#en_us_publink1000313265

Keeping inventories.(p14)

For Use in Tax Year 2013
rule
When the production, purchase, or sale of merchandise is an income-producing factor in your business, you must generally take inventories into account at the beginning and the end of your tax year. If you must account for an inventory, you must generally use an accrual method of accounting for your purchases and sales. For more information, see Inventories, later.
taxmap/pubs/p334-008.htm#en_us_publink1000313267

Special rule for related persons.(p14)

For Use in Tax Year 2013
rule
You cannot deduct business expenses and interest owed to a related person who uses the cash method of accounting until you make the payment and the corresponding amount is includible in the related person's gross income. Determine the relationship, for this rule, as of the end of the tax year for which the expense or interest would otherwise be deductible. If a deduction is not allowed under this rule, the rule will continue to apply even if your relationship with the person ends before the expense or interest is includible in the gross income of that person.
Related persons include members of your immediate family, including only brothers and sisters (either whole or half), your spouse, ancestors, and lineal descendants. For a list of other related persons, see section 267 of the Internal Revenue Code.
taxmap/pubs/p334-008.htm#en_us_publink1000313268

Combination Method(p14)

For Use in Tax Year 2013
rule
You can generally use any combination of cash, accrual, and special methods of accounting if the combination clearly shows your income and expenses and you use it consistently. However, the following restrictions apply.
taxmap/pubs/p334-008.htm#en_us_publink1000313270

Inventories(p14)

For Use in Tax Year 2013
rule
Generally, if you produce, purchase, or sell merchandise in your business, you must keep an inventory and use the accrual method for purchases and sales of merchandise. However, the following taxpayers can use the cash method of accounting even if they produce, purchase, or sell merchandise. These taxpayers can also account for inventoriable items as materials and supplies that are not incidental (discussed later).
  1. A qualifying taxpayer under Revenue Procedure 2001-10 in Internal Revenue Bulletin 2001-2.
  2. A qualifying small business taxpayer under Revenue Procedure 2002-28 in Internal Revenue Bulletin 2002-18.
taxmap/pubs/p334-008.htm#en_us_publink1000313271

Qualifying taxpayer.(p15)

Qualifying small business taxpayer.(p15)

For Use in Tax Year 2013
rule
You are a qualifying small business taxpayer if:
taxmap/pubs/p334-008.htm#en_us_publink1000313273

Business not owned or not in existence for 3 years.(p15)

For Use in Tax Year 2013
rule
If you did not own your business for all of the 3-tax-year period used in figuring your average annual gross receipts, include the period of any predecessor. If your business has not been in existence for the 3-tax-year period, base your average on the period it has existed including any short tax years, annualizing the short tax year's gross receipts.
taxmap/pubs/p334-008.htm#en_us_publink1000313274

Materials and supplies that are not incidental.(p15)

For Use in Tax Year 2013
rule
If you account for inventoriable items as materials and supplies that are not incidental, you will deduct the cost of the items you would otherwise include in inventory in the year you sell the items, or the year you pay for them, whichever is later. If you are a producer, you can use any reasonable method to estimate the raw material in your work in process and finished goods on hand at the end of the year to determine the raw material used to produce finished goods that were sold during the year.
taxmap/pubs/p334-008.htm#en_us_publink1000313275

Changing accounting method.(p15)

For Use in Tax Year 2013
rule
If you are a qualifying taxpayer or qualifying small business taxpayer and want to change to the cash method or to account for inventoriable items as non-incidental materials and supplies, you must file Form 3115, Application for Change in Accounting Method. See Change in Accounting Method, later.
taxmap/pubs/p334-008.htm#en_us_publink1000313276

Items included in inventory.(p15)

For Use in Tax Year 2013
rule

taxmap/pubs/p334-008.htm#en_us_publink1000313278

Valuing inventory.(p15)

For Use in Tax Year 2013
rule
You must value your inventory at the beginning and end of each tax year to determine your cost of goods sold (Schedule C, line 42). To determine the value of your inventory, you need a method for identifying the items in your inventory and a method for valuing these items.
Inventory valuation rules cannot be the same for all kinds of businesses. The method you use to value your inventory must conform to generally accepted accounting principles for similar businesses and must clearly reflect income. Your inventory practices must be consistent from year to year.
taxmap/pubs/p334-008.htm#en_us_publink1000313279

More information.(p15)

For Use in Tax Year 2013
rule
For more information about inventories, see Publication 538.
taxmap/pubs/p334-008.htm#en_us_publink1000313280

Uniform Capitalization Rules(p15)

For Use in Tax Year 2013
rule
Under the uniform capitalization rules, you must capitalize the direct costs and part of the indirect costs for production or resale activities. Include these costs in the basis of property you produce or acquire for resale, rather than claiming them as a current deduction. You recover the costs through depreciation, amortization, or cost of goods sold when you use, sell, or otherwise dispose of the property.
taxmap/pubs/p334-008.htm#en_us_publink1000313281

Activities subject to the uniform capitalization rules.(p15)

For Use in Tax Year 2013
rule
You may be subject to the uniform capitalization rules if you do any of the following, unless the property is produced for your use other than in a business or an activity carried on for profit.
taxmap/pubs/p334-008.htm#en_us_publink1000313282
Exceptions.(p15)
These rules do not apply to the following property.
  1. Personal property you acquire for resale if your average annual gross receipts are $10 million or less.
  2. Property you produce if you meet either of the following conditions.
    1. Your indirect costs of producing the property are $200,000 or less.
    2. You use the cash method of accounting and do not account for inventories. For more information, see Inventories, earlier.

taxmap/pubs/p334-008.htm#en_us_publink1000313285

Change in
Accounting Method(p16)

For Use in Tax Year 2013
rule
Once you have set up your accounting method, you must generally get IRS approval before you can change to another method. A change in your accounting method includes a change in:
  1. Your overall method, such as from cash to an accrual method, and
  2. Your treatment of any material item.
To get approval, you must file Form 3115, Application for Change in Accounting Method. You can get IRS approval to change an accounting method under either the automatic change procedures or the advance consent request procedures. You may have to pay a user fee. For more information, see the form instructions.
taxmap/pubs/p334-008.htm#en_us_publink1000313286

Automatic change procedures.(p16)

For Use in Tax Year 2013
rule
Certain taxpayers can presume to have IRS approval to change their method of accounting. The approval is granted for the tax year for which the taxpayer requests a change (year of change), if the taxpayer complies with the provisions of the automatic change procedures. No user fee is required for an application filed under an automatic change procedure generally covered in Revenue Procedure 2002-9.
Generally, you must use Form 3115 to request an automatic change. For more information, see the Instructions for Form 3115.
