Cash Receipts:

You should record cash receipts as income. Cash receipt includes actual receipts and constructive receipts. Cash receipts when you receive money in your hand. Constructive receipts mean amount credited to your bank account or available for you without restriction. IRS suggests you should include constructive receipt and actual receipts while filing your taxes.


Cash Expenses:

You can claim expense paid via cash or bank as deductions. However, expense paid in advance cannot be deducted in the current year. The amount should be capitalised. However, you can use 12-month rule in certain cases.


Expense paid in advance and 12 month rule:


You are required to follow 12-month rule when you pay some expense in advance and benefit of expense does not extend beyond the earlier of following:

  1. 12 month from the date of benefit begins
  2. Last date of the tax year after the tax year when payment is made.

As per 12 month rule, you can deduct 100% amount in the year of payment of expense.



  1. Alex pays $15000 as advertising expense on 28 February 2016. His tax year is the calendar year. The benefit of advertising extends up to 31 January 2017. In above case, Alex can claim $15000 as an expense as 12-month rule applies.
  2. In above case, if benefit extends up to 30 April 2017, Alex can claim $12000 as an advertising expense for 2016 and $3000 for 2017 tax year.


Accrual accounting:

Accrual accounting is the most reliable method of accounting. It shows you the true picture of profitability of business. Under accrual accounting, income is reported when it is earned and related expense should be deducted from the income. There are certain rules under US taxes about accrual method.

Let’s understand how to treat transactions as per US laws using accrual accounting.


Treatment of income:

In this method, transactions have been recorded on the earliest  of the following:

  1. when payment is received by you.

Treatment of advance received for services:

You should treat an advance as income in the year you receive the payment. However, using deferral rule, you can report this income in next tax year.


Advance received for sales:

  2. The Year when you report advance as income while preparing accounts for financial reporting.

There is some exception to above rule for inventory goods.


Please note that you should attach following statements while following alternative reporting method:

Accrual Accounting:


  1. In accrual accounting, the transaction is important. There is valid sale transaction in December month. It does not matter whether he receives money or not. So he should record $1200 sale in December month.
  2. He should record sale $1500 in December.
  3. Ben should record $2200 as income in the tax year, 2016.




There are two options to treat expense as per accrual accounting:

  5. Vacation pay can be deducted in the same year when an employee takes a vacation. You should pay this amount not later than 2.5 months after the end of the tax year.
  6. Other liabilities such as the penalty for violation of laws, refunds, rebates, the warranty should be deducted in the year of payment.

  1. The all events test is met.
  2. Items are not material or using recurring item concept, the expense match revenue in a better way following GAAP principle.
  3. The items are recurring in nature and you follow all events test for these items.
