The column answers questions most frequently asked by taxpayers. a dependent and he did not Q) My son earned nearly $2,000 last year. Does he have to file a Federal income tax return? A) If your son is single, you are not claiming him as have self-employment earn­ ings of $400 or more, he does not have to file a return be­ cause his gross income is less than $2050. However, if you or someone else could claim your son as a dependent and he had income from dividends, interest or other types of un­ earned income, he must file a return if his" gross income was at least $750. He must also file a return if he had net self-employment earnings of $400 or more. Of course, he should file a return to claim any refund due him for income tax with­ held. Q) I have all my tax rec­ ords. Can I file without my Form W-2? A) No. A withholding state­ ment, Form W-2, for each job held during 1972 must be at­ tached to your return. Failure to do so delayed the refunds of many taxpayers last year. Q) I plan to go to a com­ mercial tax preparer to hare my 1972 return filled out. Is he responsible for any errors on the^return? A) No. Each taxpayer is responsible for the accuracy of his Federal income tax re­ turn, no matter who fills it out. If you do use the services of a tax preparer this year, be sure he signs your return and enters on the form his social security number or employer identification number. Q) Is it true that this year taxpayers can designate $1 of their tax to go to a presiden­ tial election campaign fund? A) Yes. This year, taxpay­ ers, at their option, may des­ ignate $1 0f their taxes ($2 if a joint return) to go to the political party of their choice or to a nonpartisan general fund. The "check-off" is made on a separate form--IRS Form 4875--which is included in your tax forms package, and not on the Form 1040 itself. If you want to designate a dollar for the fund, complete the Form 4875 and attach it to your Form 1040. If you do not wish to earmark money for this purpose, do not file Form 4875. Q) Will the IRS still figure out a person's tax, if he wants them to? A) Yes. The Internal Rev­ enue Service will figure out your tax if your adjusted gross income is $20,000 or less and was only from wages, sal­ ary and tips, dividends, inter­ est, pensions and annuities, and if you claim the standard deduction. For more details, see your tax form instruc­ tions. Q) What do you mean by "adjusted gross income"? NEW LOCATION: 4610 W.

Adjusted gross income is arrived at by subtracting business expenses and certain employee ex­ penses, such as sick pay, mov­ ing expenses, etc. from your gross income. For most tax­ payers, however, adjusted gross income is equivalent to their total income. This year, your Form 1040 instructions contain a glos­ sary of frequently used tax terms to make it easier for you to fill out your return. Q) Are medical insurance premiums deductible in full? A) If you itemize deduc­ tions, you may deduct in full one-half of the amount you paid for medical insurance, up to $150. The balance of your premiums is added to your other medical expenses. Only your medical expenses in excess of three percent of your adjusted gToss income are deductible.

SPACE AERONAUTICS^ SKYLAB WASHINGTON -- The number of experiments to. be carried aboard Skylalb, the nation's first space sta­ tion, continues to grow as its spring launch day ap­ proaches. The number of experi­ ments and investigations have risen sharply in the last several months and their ini­ tiators include 19 U.S. high school students as well as scientists and engineers from every section of this country and 20 other nations. Altogether, the score stands at about 290 separate scientific and technical in­ vestigations for Skylab with 212 principal investigators and 383 co-investigators. Most will be analyzing Earth observations. Since last June, the number of investigations has increased by about 20 and the ranks of the investi­ gators has swelled by 165. In terms of actual on­ board experiment hardware items, Skylab is close to its limit largely because of weight constraints, the time it takes to develop and qual­ ify equipment, and the short time left for astronaut training. The 54 items of experi­ mental equipment already selected by NASA for the big manned spacecraft will gen­ erate voluminous raw data about Earth resources, solar and stellar physics, life sciences, and materials proc­ essing in zero gravity. It is anticipated large amounts of available data from space that keeps gener­ ating new ideas on ways it can be applied to Earth- bound interests and adds to the number of approved Sky­ lab data-use investigators. For example, Earth re­ sources data from five sen­ sors will go to 146 principal investigators and 366 co- investigators. Additional experiments are not limited to finding new uses of data. Innovative de­ sign and engineering that substituted one metal proc­ essing piece of equipment for another will allow the per­ formance of 10 additional experiments without any penalty in weight, cost, or size. Skylab will be operational for about eight months in Earth orbit and will be visited three times by crews of three astronauts. The spacecraft cluster is due to be launched April 30. The first manned visit will last up to 28 days, the others up to 56 days. Todo/s Heolth News Published by the American Medical Association Look, Ma! No cavities . . . Im­ possible? Not according to a band of dental enthusiasts who are preaching the new gospel of pre­ ventive dentistry. They claim: "You can keep all your teeth all your life. You don't have to suffer from cavities or bleeding gums." The secret is a technique known as "plaque control." And recent research has proved it can stop gum diseases--and save teeth. Plaque is a transparent, sticky coating formed by the mixture of saliva with the accumulated mi­ croscopic germs on the teeth and gums present even in healthy mouths. These germs infect the gums and make acids which at­ tack the teeth. Often they are the cause of bad breath. Plaque takes about 24 hours to build up on clean teeth, so the solution seems obvious: Remove the plaque once a day. Easier said than done, however. Plaque is transparent, hard to see. It's possible to brush and brush and still leave traces of plaque on the sides and backs of the teeth. Many of the plaque control den­ tists are teaching their patients how to remove plaque. Some ad­ vocate use of a red food-coloring dye which, when chewed, leaves a red stain on plaque and food particles, but not on clean teeth. Others show patients how to clean the surfaces of their teeth with wiggly motions ot a special soft- bristle brush. Some use small mirrors with long handles that help the patient see the backs of his teeth. Others show patients how to clean the sides of the teeth with dental floss. Techniques vary. But many dentists are skeptical about the entire approach. In fact, only some 15 percent of dentists in the U.S. advocate this form of preventive dentistry as the end- all. Viron Diefenbach, the assist­ ant executive director of the American Dental Association, for one, worries that plaque control will overshadow other practices considered part of preventive den­ tistry--including fluoridation and proper diet. And John Green, D.M.D., who directs the dental division of the U.S. Public Health Service, says, "There is a limit to how much you can manage plaque --it's not going to completely solve the decay problem." Still, a recent survey of dentists showed that while the great ma­ jority are not giving their patients instructions in plaque control, many are interested in starting such programs. The problem, then: convincing the American public -- twenty million of whom have lost all their natural teeth -- that spending five minutes a day for clean teeth is worth the trouble.
