Maximising interest income from investments
S. R. Balachandran
When we deposit money in Treasury Bills, Banks and Financial
Institutes, we receive interest. With effect from 2002/2003 withholding
Tax of 10 percent was introduced on the interest income. Several
amendments have been subsequently effected to rectify certain anomalies.
At present the Withholding Tax procedure is as follows:
a. If an individual gives a declaration to a bank or financial
institute, that his total annual income (employment, deposits, other
sources etc) is less than Rs 300,000 no tax is deducted.
b. If the income exceeds Rs 300,000 up to the limit of one
million a withholding Tax of 2.5 percent will be deducted on the
interest.
c. If the total income interest exceeds one million tax will
be deducted at the rate of 10 percent.
The following factors should be considered:
1. The interest on which Withholding Tax has been deducted is tax free.
2. Income from Treasury Bills is also tax free and it is not counted
when computing total income for withholding Tax purpose by a Bank or
Finance Institutes.
3. If a person is 59 years old on April 1 of any year of assessment he
is entitled to an additional exemption for Rs 200,000 provided he makes
deposits in selected Government banks.
Individuals should carefully allocate their funds to enjoy tax
exemptions. For example if a person's interest from a bank is Rs 600,000
per year the withholding Tax would be Rs 15,000 (2.5 percent). If he
receives the entire Rs 600,000 from Treasury Bills it is tax free.
If he receives Rs 300,000 Treasury Bill income and Rs 300,000 from
Bank deposits again it is tax free. If his income is Rs 1,100,000 the
withholding Tax would be Rs 110,000.
If he receives the entire income from the Treasury Bills it is tax
free. If he receives One Million from a Bank as interest and the balance
from the Treasury Bills only Rs 25,000 would be deducted.
Therefore if allocation is made professionally tax benefit could be
maximized. At present the income from Treasury Bills is low (8 percent).
A Bank may offer interest rate more than 8 percent. I quote below the
following cases:
1. Treasury Bill income and Bank interest are same
2. Treasury Bill income is more than Bank interest
3. Bank interest is more than Treasury Bills income but within the range
of 2.5641 percent. i.e. if the Treasury Bill income is 8 percent the
Bank interest is within 8.205 percent.
4. Bank interest is more than Treasury Bill income but within the limit
of IT. 11 percent i.e. if the Treasury Bill income is 8 percent the bank
interest is more than 8.205 percent (say 8.5 percent) but within 8.89
percent.
5. Bank interest is more than Treasury Bill income by 11.11 percent i.e.
Treasury Bill is 8 percent Bank Interest is more than 8.89 percent.
Now deposit allocation is as follows:
a. In the first case mentioned in the above deposit all your funds
in Treasury Bill
b. In the second case mentioned in the above deposit all your
funds in Treasury Bill
c. In the third case
Up to Rs 300,000 income deposit in Bank
If it exceeds Rs 300,000
First Rs 300,000 income from Bank
Balance from Treasury Bills
Even if the income exceeds one million this procedure is applicable.
X = 8.00 percent (say)
Y = 8.20 percent (say)
d. In the fourth case where the bank interest is more than
102.564 percent of Treasury Bills income you have to compute Break Even
Interest using Mathematical formula details of which are quoted
separately.
Up to first Rs 300,000 place it in the bank. When it exceeds Rs
300,000 but within Break Even Interest place the excess investment in
Treasury Bills.
If the interest is more than Break Even Interest up to Rs one million
place the entire
deposit in the bank (No Treasury Bills)
If the income exceeds Rs One Million
Up to Rs one million place it in bank
Balance in Treasury Bills
Now I quote below the method of computing Break Even Interest
Treasury Bills income X% - 8.00% (say)
Bank Interest Break Y% - 8.50% (say)
Even Interest 1% - 521,740* (see the computation below)
I (100 - 2.5) - 300,000 x 100
----- --
Y Y - X Y
e. In the Fifth case Bank Interest is more than 11.11 percent of
Treasury Bills new Break Even Interest has to be computed using new
formula in addition to old formula.
I
"100 - 7.5
-- -- 1,000,000 X 100
Y 97.5 Y-X --
----- Y
100
X = 8.00% (say)
Y = 9.00% (say)
I = 7749955 (See the computation above) and 387096 (old formula)
Up to Break Even Interest - Bank interest 300,000 and balance in
Treasury Bills only Above Break Even Interest to 1,000,000 - Bank
interest only (No Treasury Bills) Above 1,000,000 up to second Break
Even Interest - Bank Interest up to 1,000,000 Balance Treasury Bills
only.
Above second Break Even Interest Bank Interest only.
Now we have to consider the case where the investor is having other
income as well (employment and other sources). Let this be called "A".
The following allocations have to be made:
1. In the case One no change - entire deposit in Treasury Bills
2. In the case Two no change - entire deposit in Treasury Bills
3. In the case Three there is no Break Even Interest. (A would be more
than 300,000) (see the formula below)
I (100 - 2.5 = (300,000 -A) x 100
-- -- --
Y Y-X Y
Up to total interest of 300,000 Bank Deposits only. Beyond which the
balance in Treasury Bills only.
4. In the case Four new Break Even Interest has to be computed
according to the same formula (A would be less than 300,000)
X = 8.00 (say) Y =
8.50 (say) A =
200,000 (say)
1 = 173,913 - I 100 - 2.5 = (300,000 - 200,000) x 100
-- -- --
8.50 8.50 - 8.00 8.5
Up to the total income of 300,000 (employment, deposits and other
sources) only bank deposits are possible.
From 300,000 to the total income of Break Even Interest and other
income place Excess Investment in Treasury Bills.
Thereafter up to one million (total income) entire deposits in Bank.
Balance over and above one million in Treasury Bills.
5. In the case of Five, Break Even Interest should be computed using
second formula
I 100 - 7.5 = (1,000,000 - A) X 100
-- -- --
Y 97.5Y - X Y
---
100
X = 8% (say)
Y = 9% (say)
A = 700,000 and 200,000
I = 2324986 (see the computation above) and 129032 (Old formula)
6201392 (New formula)
