#JavaScript (ES6) 52

A function returning the output as an array.

(y=(new Date).getYear())=>[(y+~(y/4)-13)/10,y*3-20]

Just for testing purpose, the function accepts an input equals to current year - 1900 (e.g. 105 for 2015)

That's in the line of the ETHproductions' answer (the math is the math) but avoding the evil trick it is more portable in different locales. And as a function it's 1 byte shorter.

Test snippet:

f=(y=(new Date).getYear())=>[(y+~(y/4)-13)/10,y*3-20]

o=[];
for(a=2000;a<2050;a++)o.push(`<td>${a}</td><td>${f(a-1900)}</td>`);
document.write(`<table><tr>${o.join`</tr><tr>`}</tr></table>`)

td { text-align:right; font-family:monospace }

f=(y=(new Date).getYear()=>[(y+~(y/4)-13)/10,y*3-20]
