# Impact of income tax on capital budgeting decisions

The income tax usually have a significant effect on the cash flow of a company and should be taken into account while making capital budgeting decisions. An investment that looks desirable without considering income tax may become unacceptable after considering income tax. Before explaining the impact of income tax on capital budgeting using a net present value example, we need to understand three concepts. These are **after-tax benefit**, **after-tax cost** and **depreciation tax shield**. A brief explanation of each is given below:

## After-tax benefit or cash inflow:

Taxable revenues or cash inflows, when reduced by the income tax, are known as * after-tax benefit* or

*. When income tax is considered in capital budgeting decisions, after-tax cash inflow is used. An example of taxable cash inflow is cash generated by a company from its operations.*

**after-tax cash inflow**After tax benefit or after tax cash inflow can be easily computed using the following formula:

**After-tax benefit or after-tax cash inflow = (1 – Tax rate) × Taxable cash receipt**

### Example 1:

XYZ company generated $10,000 cash from its operations. The tax rate of the company is 30%. Compute after-tax cash inflow.

#### Solution:

After-tax benefit or after-tax cash inflow = (1 – Tax rate) × Taxable cash receipt

= (1 – 0.3) × $10,000

= 0.7 × $10,000

= $7,000

## After-tax cost:

Tax deductible costs reduce taxable income and help save income tax. A cost net of its tax effect is known as * after-tax cost*. After-tax cost can be computed using the following formula:

**After-tax cost or after tax cash outflow = (1 – Tax rate) × Tax deductible cash expense**

### Example 2:

A company wants to start a training program that will cost $50,000. The training program is a tax deductible cost for the company. Compute after-tax cost of training program if tax rate of the company is 30%.

#### Solution:

After-tax cost or after tax cash outflow = (1 – Tax rate) × Tax deductible cash expense

= (1 – 0.3) × $50,000

= 0.7 × $50,000

= $35,000

## Depreciation tax shield:

Depreciation is a non-cash tax deductible expense that saves income tax by reducing taxable income. The amount of tax that is saved by depreciation is known as * depreciation tax shield*. The formula to compute depreciation tax shield is as follows:

**Depreciation tax shield = Tax rate × Depreciation deduction**

### Example 3:

The annual tax deductible depreciation of a company is $25,000 and tax rate is 30%. Compute tax savings from depreciation (depreciation tax shield).

#### Solution:

Depreciation tax shield = Tax rate × Depreciation deduction

= 0.3 × $25,000

= $7,500

## Capital budgeting with income tax:

As the after-tax cash inflow, after-tax cost and depreciation tax shield have been discussed, We can explain the impact of income tax on capital budgeting with the help of a comprehensive example.

### Example 4:

A company is considering the purchase of an equipment to save its costs. The relevant data for net present value analysis of the equipment is given below:

- Cost of the equipment: $240,000
- Expected annual cash savings before tax to be provided by the equipment: $100,000
- Useful life of the equipment: 6 years
- Expected residual or salvage value of the equipment at the end of 6 year period: $30,000
- Tax rate: 40%
- Discount rate: 12%

The equipment is to be depreciated using straight line method of depreciation. The company does not deduct salvage value from the cost of the equipment for computing depreciation for tax purpose.

**Required:** Determine net present value of the investment.

#### Solution:

Depreciation = $240,000/6 years

= $40,000

* Value from present value of an annuity of $1 in arrears table.

** Value from present value of $1 table.

Residual value (salvage value) is taxable because it has not been considered while computing depreciation. At the end of the useful life, the equipment will have a book value of zero.

Depreciation = $240,000/6 years

@Matt It is depreciation.

Cost/Useful life of the equipment

240,000/6

=40,000

Shouldn’t SL depreciation equal purchase cost – estimated salvage value, then divided by useful life?

($240,000 – $30,000)/6 yrs? Which equals depreciation of $35,000 per year.

Yes that’s right. However, the problem explicitly stated that “The company does not deduct salvage value from the cost of equipment for computing depreciation…” which is still fine since this scope falls more on under managerial accounting rather than financial accounting.

how do we arrived at 4.111 ( present value factor )using 1-6 years

because when look into present value of annuity you find the factor of 12% in 6 years it is same thing whether you use annuity or just present value for consecutive 6 years, on summations of 6 you will find 4.11

1/1.12. = .8929

.8929 /1.12 =.7972

.7972/1.12 =.7118

.7118/1.12 =.6355

.6355/1.12 =.5674

.5674/1.12 =.5066

Total. =4.111

clear working but derivation of 4.111 should be explained

Hi,

Can I side-track and ask if there is a requirement in increased inventory and additional sales and administrative personnel costs, do we have to deduct tax too?

where are the tax factors of 0.6,0.4 and 0.6 from

how do we treat investment tax credit in capital budgeting?

Hello,

Why is the discount rate used not after-tax also? When do we use after-tax discount rate in capital budgeting?

Thank you
