+6 oxidation state
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
The oxidation state of sulfur in SO3 is +6. Each oxygen atom has an oxidation state of -2, and since the overall charge of SO3 is 0, the oxidation state of sulfur must be +6 to balance out the charges.
The oxidation number of Na in Na2SO3 is +1, the oxidation number for S in SO3 is +4, and the oxidation number for O in SO3 is -2.
In SO3, sulfur has an oxidation number of +6 and each oxygen atom has an oxidation number of -2.
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.

Sulfur has an oxidation state of +4 in SO3^2-. Each oxygen atom has an oxidation state of -2.
The oxidation number of Na in Na2SO3 is +1, the oxidation number for S in SO3 is +4, and the oxidation number for O in SO3 is -2.
In SO3, sulfur has an oxidation number of +6 and each oxygen atom has an oxidation number of -2.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
In SO3^2-, sulfur has an oxidation state of +4 (Sulfur's typical oxidation state is +6 and each oxygen has an oxidation state of -2, so the total charge of the ion of -2 corresponds to sulfur being in a +4 oxidation state).
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
S has an oxidation state of +4 in a sulfite anion as stated. In oxyanions, oxygen always has an oxidation state of -2. Therefore, three oxygen atoms will have total oxidation number of -6, requiring an oxidation number of +4 for sulfur to sum to the charge of -2 on the anion as a whole.

When calculating oxidation numbers, use '-2' (oxygen) as the 'yardstick'(standard). Since SO3 has three oxygens, then the oxygen moiety is 3 x -2 = -6 Since SO3 is a neutrally charged molecule, overall oxidation is '0'. Hence S + -6 = 0 Hence S = 6 is the oxudation number for sulphur. NB Sulphur exhibits different oxidation states in different molecules. S = 0 SO2 = 4 SO3 = 6 ( as above) H2SO4) = 6 H2S2O7 (Oleum) = 6
SO3 is a covalent compound, not ionic. It is called sulfur trioxide.
