For taxable years beginning in 1971, the standard deduction shall be 13% of gross income or $1,500.00, whichever is less; for taxable years beginning in 1972, the standard deduction shall be 14% or $2,000.00, whichever is less; for taxable years beginning in 1973 the standard deduction shall be 15% or $2,000.00, whichever is less; for taxable years beginning in 1978 the standard deduction shall be 16% or $2,400.00, whichever is less; and for taxable years beginning in 1981 and thereafter the standard deduction shall be 17% or $2,500.00, whichever is less.
A husband and wife shall not be entitled to a standard deduction in an amount greater than one computed on their aggregate gross income, whether they file separate or joint returns. If they file separate returns, neither may elect the standard deduction unless the other also so elects. If both so elect, either may take such deduction, or they may divide it; except that for taxable years beginning in 1971 the standard deduction shall be 13% of gross income or $1,500.00, whichever is less: for taxable years beginning in 1972 the standard deduction shall be 14% or $2,000.00, whichever is less; for taxable years beginning in 1973 the standard deduction shall be 15% or $2,000.00, whichever is less; for taxable years beginning in 1978 the standard deduction shall be 16% or $2,400.00, whichever is less; and for taxable years beginning in 1981 and thereafter the standard deduction shall be 17% or $2,500.00, whichever is less.
Such election may be changed for a taxable year after the filing of the return, subject to regulations issued under this act. If a taxpayer wishing to make such change has a spouse who filed a separate return, the change shall not be allowed unless (1) such spouse also makes a change consistent with the change desired by the taxpayer and (2) both consent in writing to the assessment of any additional tax resulting from such change without regard to time limits otherwise preventing such assessment.
